Lecture Is Dead
Long Live Lecture
How and why to make class time more exciting and rewarding for your students

Ten and Two Hike 10 minute lecture 2 minutes to chew on it
Similar to commercial breaks
BUT you engage the students
Think of a TV program

Brain Rules The brain seems to rely partly
on past experience in deciding how to learn new things
Make sure they understand what is new each time
Our senses evolved to work together
We learn best if we stimulate several senses at once
Patterns and Connections We are better at seeing
patterns and abstracting the meaning of an event than we are at recording detail
Emotional arousal helps the brain learn
So make it emotional
Memory and Brain Rules Most memories disappear
within minutes
How do we make sure it gets into long-term memory
Incorporate new information gradually
Repeat it in timed intervals
Brain RulesBabies are the model of how we learn
observation

Darn Kids these days
This is not just about ldquokids these daysrdquo this research is decades old
Brains more wired for linear bursts than deep thinking (always on etc)

Problem SolvingDONrsquoT Just Tell Them What to Do

Exercises vs Problems
ExercisePractice a rule or procedure
Factor this polynomial
Solve this equation
Find the distance between these two points
Differentiate these functions
The student is told exactly what to do
ProblemA problem usually requires more thinking and analysis In most cases there is no formula that immediately gives the answer
Find a point on a given line which is equidistant from two given points

Ever Heard This
ldquoOnce I know what to do itrsquos easy My trouble is knowing where to startrdquo
ldquoDonrsquot make me try to understand this just tell me what to dordquo
73
In the ldquoreal worldrdquohellip
1 Whose job is it to ldquounderstand the problemrdquo(Usually company officers and executives)
2 Whose job is it to ldquodevise a plan or strategyrdquo(Usually the managers and engineers)
74
In the ldquoreal worldrdquohellip
3 Whose job is it to ldquocarry out the planrdquo(Usually the assistants clerks and laborers)
4 Whose job is it to ldquolook backrdquo and see if a satisfactory outcome has been achieved(Usually the officers and executives again)
75
Who are the lowest paid
1 Company officers and executives
2 Managers and engineers
3 Assistants clerks and laborers
4 Company officers and executives
Who are most likely to be replaced by automation outsourcing or a computer1 Company officers or executives
2 Managers or engineers
3 Assistants clerks or laborers
4 Company officers or executives
77
So if we focus almost entirely on step 3 ldquocarry out the planrdquo what are we preparing our students for
78
A thorough knowledge of what skills techniques and procedures are possible is necessary especially to those who ldquodevise a planrdquo
But this is not sufficient
79
To fully prepare our students for a productive (and well paying) career we must emphasize all facets of problem solving

OTHER Important Tidbits Optional The use of FB is optional but I
always strongly recommend it For those who are FB-haters I tell them that they can create an account with their school email and only use it for this purpose Once in a blue moon I have someone who is adamantly against FB so I just tell them that its their responsibility to get info from a classmate or myself

How Math is Like Golf
Laurie K McManus PhDProfessor of MathematicsSt Louis CC ndash Meramec
lmcmanusstlcceduwwwmcmathprofcom
There are rules that must be followed
You must use the proper equipment
Your skills improve with regular practice
Sometimes itrsquos necessary to consult an expert
Your skills do not improve by watching someone else play the
game
Patience hellip
Persistence may be rewarded
Sometimes you have to calculate
You must be prepared to interpret the result of your
calculations
A good score can be very satisfying
It can be a social activity
Sometimes itrsquos fun
And now for something completely different hellip

Dear Math
I am sick and tired of finding
your ldquoxrdquo Just accept the fact
she is gone Move on Dude
314 of sailors are Pi Rates
Q Why cant you say 288 in publicA Its two gross
Very Bad Math JokesQ What did the zero say to the
eightA Nice belt
Q How does a cow add
A It adds one udder to an udder
Q Why is the snake so good at math
A Because hersquos an adder
Even Worse Math JokesQ Why is the math book so upsetA Because it has lots of problems
Q What did the math plan grow
A Square roots
Q How do you make seven evenA Take away the ldquosrdquo
Q What did the dollar say to the 4
quartersA Yoursquove changed
There are 10 kinds of mathematicians Those who can think binarily and those who cant
Whats your favorite thing about
mathematics Knot theory
Yeah me neither
In Alaska where it gets very cold pi is only 300 As you know everything shrinks in the cold They call it Eskimo
pi
Q What does the little
mermaid wear A An Alge-bra

Discovering the Art of Mathematics Project
Julian Fleron Phil Hotchkiss Volker Ecke Christine von Renesse Westfield State University Massachusetts
This project is based upon work currently supported by the National Science Foundation under NSF1225915 (TUES) and previously supported by NSF0836943 (CCLI) and a gift
from Mr Harry Lucas
Our Vision
Mathematics for Liberal Arts students will be actively involved in authentic mathematical experiences that
are both challenging and intellectually stimulating
provide meaningful cognitive and metacognitive gains and
nurture healthy and informed perceptions of mathematics mathematical ways of thinking and the ongoing impact of mathematics not only on STEM fields but also on the liberal arts and humanities

Brain Rules The brain seems to rely partly
on past experience in deciding how to learn new things
Make sure they understand what is new each time
Our senses evolved to work together
We learn best if we stimulate several senses at once
Patterns and Connections We are better at seeing
patterns and abstracting the meaning of an event than we are at recording detail
Emotional arousal helps the brain learn
So make it emotional
Memory and Brain Rules Most memories disappear
within minutes
How do we make sure it gets into long-term memory
Incorporate new information gradually
Repeat it in timed intervals
Brain RulesBabies are the model of how we learn
observation
hypothesis
experiment
conclusion
Darn Kids these days
This is not just about ldquokids these daysrdquo this research is decades old
Brains more wired for linear bursts than deep thinking (always on etc)

Ever Heard This
ldquoOnce I know what to do itrsquos easy My trouble is knowing where to startrdquo
ldquoDonrsquot make me try to understand this just tell me what to dordquo

In the ldquoreal worldrdquohellip
1 Whose job is it to ldquounderstand the problemrdquo(Usually company officers and executives)
2 Whose job is it to ldquodevise a plan or strategyrdquo(Usually the managers and engineers)
74
In the ldquoreal worldrdquohellip
3 Whose job is it to ldquocarry out the planrdquo(Usually the assistants clerks and laborers)
4 Whose job is it to ldquolook backrdquo and see if a satisfactory outcome has been achieved(Usually the officers and executives again)
75
Who are the lowest paid
1 Company officers and executives
2 Managers and engineers
3 Assistants clerks and laborers
4 Company officers and executives
Who are most likely to be replaced by automation outsourcing or a computer1 Company officers or executives
2 Managers or engineers
3 Assistants clerks or laborers
4 Company officers or executives
77
So if we focus almost entirely on step 3 ldquocarry out the planrdquo what are we preparing our students for
78
A thorough knowledge of what skills techniques and procedures are possible is necessary especially to those who ldquodevise a planrdquo
But this is not sufficient
79
To fully prepare our students for a productive (and well paying) career we must emphasize all facets of problem solving

OTHER Important Tidbits Policy I have a very clear written policy
on the use of this forum stated on the About section of the class FB page I warn them that any inappropriate use of the forum results in immediate removal from the group (although this has never been an issue)
OTHER Important Tidbits Optional The use of FB is optional but I
always strongly recommend it For those who are FB-haters I tell them that they can create an account with their school email and only use it for this purpose Once in a blue moon I have someone who is adamantly against FB so I just tell them that its their responsibility to get info from a classmate or myself

There are rules that must be followed
You must use the proper equipment
Your skills improve with regular practice
Sometimes itrsquos necessary to consult an expert
Your skills do not improve by watching someone else play the
game
Patience hellip
Persistence may be rewarded
Sometimes you have to calculate
You must be prepared to interpret the result of your
calculations
A good score can be very satisfying
It can be a social activity
Sometimes itrsquos fun
And now for something completely different hellip

Brain Rules The brain seems to rely partly
on past experience in deciding how to learn new things
Make sure they understand what is new each time
Our senses evolved to work together
We learn best if we stimulate several senses at once
Patterns and Connections We are better at seeing
patterns and abstracting the meaning of an event than we are at recording detail
Emotional arousal helps the brain learn
So make it emotional
Memory and Brain Rules Most memories disappear
within minutes
How do we make sure it gets into long-term memory
Incorporate new information gradually
Repeat it in timed intervals
Brain RulesBabies are the model of how we learn

Brain Rules The brain seems to rely partly
on past experience in deciding how to learn new things
Make sure they understand what is new each time
Our senses evolved to work together
We learn best if we stimulate several senses at once
Patterns and Connections We are better at seeing
patterns and abstracting the meaning of an event than we are at recording detail
Emotional arousal helps the brain learn
So make it emotional

How do we make sure it gets into long-term memory
Incorporate new information gradually

Ever Heard This
ldquoOnce I know what to do itrsquos easy My trouble is knowing where to startrdquo
ldquoDonrsquot make me try to understand this just tell me what to dordquo
73
In the ldquoreal worldrdquohellip
1 Whose job is it to ldquounderstand the problemrdquo(Usually company officers and executives)
2 Whose job is it to ldquodevise a plan or strategyrdquo(Usually the managers and engineers)
74
In the ldquoreal worldrdquohellip
3 Whose job is it to ldquocarry out the planrdquo(Usually the assistants clerks and laborers)
4 Whose job is it to ldquolook backrdquo and see if a satisfactory outcome has been achieved(Usually the officers and executives again)
75
Who are the lowest paid
1 Company officers and executives
2 Managers and engineers
3 Assistants clerks and laborers
4 Company officers and executives
Who are most likely to be replaced by automation outsourcing or a computer1 Company officers or executives
2 Managers or engineers
3 Assistants clerks or laborers
4 Company officers or executives
77
So if we focus almost entirely on step 3 ldquocarry out the planrdquo what are we preparing our students for
78
A thorough knowledge of what skills techniques and procedures are possible is necessary especially to those who ldquodevise a planrdquo
But this is not sufficient
79
To fully prepare our students for a productive (and well paying) career we must emphasize all facets of problem solving

OTHER Important Tidbits Policy I have a very clear written policy
on the use of this forum stated on the About section of the class FB page I warn them that any inappropriate use of the forum results in immediate removal from the group (although this has never been an issue)
OTHER Important Tidbits Optional The use of FB is optional but I
always strongly recommend it For those who are FB-haters I tell them that they can create an account with their school email and only use it for this purpose Once in a blue moon I have someone who is adamantly against FB so I just tell them that its their responsibility to get info from a classmate or myself

There are rules that must be followed
You must use the proper equipment
Your skills improve with regular practice
Sometimes itrsquos necessary to consult an expert
Your skills do not improve by watching someone else play the
game
Patience hellip
Persistence may be rewarded
Sometimes you have to calculate
You must be prepared to interpret the result of your
calculations
A good score can be very satisfying
It can be a social activity
Sometimes itrsquos fun

Ever Heard This
ldquoOnce I know what to do itrsquos easy My trouble is knowing where to startrdquo
ldquoDonrsquot make me try to understand this just tell me what to dordquo
73
In the ldquoreal worldrdquohellip
1 Whose job is it to ldquounderstand the problemrdquo(Usually company officers and executives)
2 Whose job is it to ldquodevise a plan or strategyrdquo(Usually the managers and engineers)
74
In the ldquoreal worldrdquohellip
3 Whose job is it to ldquocarry out the planrdquo(Usually the assistants clerks and laborers)
4 Whose job is it to ldquolook backrdquo and see if a satisfactory outcome has been achieved(Usually the officers and executives again)
75
Who are the lowest paid
1 Company officers and executives
2 Managers and engineers
3 Assistants clerks and laborers
4 Company officers and executives
Who are most likely to be replaced by automation outsourcing or a computer1 Company officers or executives
2 Managers or engineers
3 Assistants clerks or laborers
4 Company officers or executives
77
So if we focus almost entirely on step 3 ldquocarry out the planrdquo what are we preparing our students for
78
A thorough knowledge of what skills techniques and procedures are possible is necessary especially to those who ldquodevise a planrdquo
But this is not sufficient
79
To fully prepare our students for a productive (and well paying) career we must emphasize all facets of problem solving

OTHER Important Tidbits Optional The use of FB is optional but I
always strongly recommend it For those who are FB-haters I tell them that they can create an account with their school email and only use it for this purpose Once in a blue moon I have someone who is adamantly against FB so I just tell them that its their responsibility to get info from a classmate or myself

How Math is Like Golf
Laurie K McManus PhDProfessor of MathematicsSt Louis CC ndash Meramec
lmcmanusstlcceduwwwmcmathprofcom
There are rules that must be followed
You must use the proper equipment
Your skills improve with regular practice
Sometimes itrsquos necessary to consult an expert
Your skills do not improve by watching someone else play the
game
Patience hellip
Persistence may be rewarded
Sometimes you have to calculate
You must be prepared to interpret the result of your
calculations
A good score can be very satisfying
It can be a social activity
Sometimes itrsquos fun
And now for something completely different hellip

Brain Rules The brain seems to rely partly
on past experience in deciding how to learn new things
Make sure they understand what is new each time
Our senses evolved to work together
We learn best if we stimulate several senses at once
Patterns and Connections We are better at seeing
patterns and abstracting the meaning of an event than we are at recording detail
Emotional arousal helps the brain learn
So make it emotional
Memory and Brain Rules Most memories disappear
within minutes
How do we make sure it gets into long-term memory
Incorporate new information gradually
Repeat it in timed intervals
Brain RulesBabies are the model of how we learn
observation
hypothesis
experiment
conclusion
Darn Kids these days
This is not just about ldquokids these daysrdquo this research is decades old
Brains more wired for linear bursts than deep thinking (always on etc)

Our Vision
Mathematics for Liberal Arts students will be actively involved in authentic mathematical experiences that
are both challenging and intellectually stimulating
provide meaningful cognitive and metacognitive gains and
nurture healthy and informed perceptions of mathematics mathematical ways of thinking and the ongoing impact of mathematics not only on STEM fields but also on the liberal arts and humanities

Brain Rules The brain seems to rely partly
on past experience in deciding how to learn new things
Make sure they understand what is new each time
Our senses evolved to work together
We learn best if we stimulate several senses at once
Patterns and Connections We are better at seeing
patterns and abstracting the meaning of an event than we are at recording detail
Emotional arousal helps the brain learn
So make it emotional
Memory and Brain Rules Most memories disappear
within minutes
How do we make sure it gets into long-term memory
Incorporate new information gradually
Repeat it in timed intervals
Brain RulesBabies are the model of how we learn

Darn Kids these days
This is not just about ldquokids these daysrdquo this research is decades old
Brains more wired for linear bursts than deep thinking (always on etc)

ldquoDonrsquot make me try to understand this just tell me what to dordquo
73
In the ldquoreal worldrdquohellip
1 Whose job is it to ldquounderstand the problemrdquo(Usually company officers and executives)
2 Whose job is it to ldquodevise a plan or strategyrdquo(Usually the managers and engineers)
74
In the ldquoreal worldrdquohellip
3 Whose job is it to ldquocarry out the planrdquo(Usually the assistants clerks and laborers)
4 Whose job is it to ldquolook backrdquo and see if a satisfactory outcome has been achieved(Usually the officers and executives again)
75
Who are the lowest paid
1 Company officers and executives
2 Managers and engineers
3 Assistants clerks and laborers
4 Company officers and executives
Who are most likely to be replaced by automation outsourcing or a computer1 Company officers or executives
2 Managers or engineers
3 Assistants clerks or laborers
4 Company officers or executives
77
So if we focus almost entirely on step 3 ldquocarry out the planrdquo what are we preparing our students for
78
A thorough knowledge of what skills techniques and procedures are possible is necessary especially to those who ldquodevise a planrdquo
But this is not sufficient
79
To fully prepare our students for a productive (and well paying) career we must emphasize all facets of problem solving

Brain Rules The brain seems to rely partly
on past experience in deciding how to learn new things
Make sure they understand what is new each time
Our senses evolved to work together
We learn best if we stimulate several senses at once
Patterns and Connections We are better at seeing
patterns and abstracting the meaning of an event than we are at recording detail
Emotional arousal helps the brain learn
So make it emotional
Memory and Brain Rules Most memories disappear
within minutes
How do we make sure it gets into long-term memory
Incorporate new information gradually
Repeat it in timed intervals
Brain RulesBabies are the model of how we learn

Ever Heard This
ldquoOnce I know what to do itrsquos easy My trouble is knowing where to startrdquo
ldquoDonrsquot make me try to understand this just tell me what to dordquo
73
In the ldquoreal worldrdquohellip
1 Whose job is it to ldquounderstand the problemrdquo(Usually company officers and executives)
2 Whose job is it to ldquodevise a plan or strategyrdquo(Usually the managers and engineers)
74
In the ldquoreal worldrdquohellip
3 Whose job is it to ldquocarry out the planrdquo(Usually the assistants clerks and laborers)
4 Whose job is it to ldquolook backrdquo and see if a satisfactory outcome has been achieved(Usually the officers and executives again)
75
Who are the lowest paid
1 Company officers and executives
2 Managers and engineers
3 Assistants clerks and laborers
4 Company officers and executives
Who are most likely to be replaced by automation outsourcing or a computer1 Company officers or executives
2 Managers or engineers
3 Assistants clerks or laborers
4 Company officers or executives
77
So if we focus almost entirely on step 3 ldquocarry out the planrdquo what are we preparing our students for
78
A thorough knowledge of what skills techniques and procedures are possible is necessary especially to those who ldquodevise a planrdquo
But this is not sufficient
79
To fully prepare our students for a productive (and well paying) career we must emphasize all facets of problem solving

on the use of this forum stated on the About section of the class FB page I warn them that any inappropriate use of the forum results in immediate removal from the group (although this has never been an issue)
OTHER Important Tidbits Optional The use of FB is optional but I
always strongly recommend it For those who are FB-haters I tell them that they can create an account with their school email and only use it for this purpose Once in a blue moon I have someone who is adamantly against FB so I just tell them that its their responsibility to get info from a classmate or myself

There are rules that must be followed

Your skills improve with regular practice
Sometimes itrsquos necessary to consult an expert
Your skills do not improve by watching someone else play the
game
Patience hellip
Persistence may be rewarded
Sometimes you have to calculate
You must be prepared to interpret the result of your

A good score can be very satisfying
It can be a social activity

Problem SolvingDONrsquoT Just Tell Them What to Do

Exercises vs Problems
ExercisePractice a rule or procedure
Factor this polynomial
Solve this equation
Find the distance between these two points
Differentiate these functions
The student is told exactly what to do
ProblemA problem usually requires more thinking and analysis In most cases there is no formula that immediately gives the answer
Find a point on a given line which is equidistant from two given points

Ever Heard This
ldquoOnce I know what to do itrsquos easy My trouble is knowing where to startrdquo
ldquoDonrsquot make me try to understand this just tell me what to dordquo
73
In the ldquoreal worldrdquohellip
1 Whose job is it to ldquounderstand the problemrdquo(Usually company officers and executives)
2 Whose job is it to ldquodevise a plan or strategyrdquo(Usually the managers and engineers)
74
In the ldquoreal worldrdquohellip
3 Whose job is it to ldquocarry out the planrdquo(Usually the assistants clerks and laborers)
4 Whose job is it to ldquolook backrdquo and see if a satisfactory outcome has been achieved(Usually the officers and executives again)
75
Who are the lowest paid
1 Company officers and executives
2 Managers and engineers
3 Assistants clerks and laborers
4 Company officers and executives
Who are most likely to be replaced by automation outsourcing or a computer1 Company officers or executives
2 Managers or engineers
3 Assistants clerks or laborers
4 Company officers or executives
77
So if we focus almost entirely on step 3 ldquocarry out the planrdquo what are we preparing our students for
78
A thorough knowledge of what skills techniques and procedures are possible is necessary especially to those who ldquodevise a planrdquo
But this is not sufficient
79
To fully prepare our students for a productive (and well paying) career we must emphasize all facets of problem solving

There are rules that must be followed
You must use the proper equipment
Your skills improve with regular practice
Sometimes itrsquos necessary to consult an expert
Your skills do not improve by watching someone else play the
game
Patience hellip
Persistence may be rewarded
Sometimes you have to calculate
You must be prepared to interpret the result of your
calculations
A good score can be very satisfying
It can be a social activity
Sometimes itrsquos fun

Our Vision
Mathematics for Liberal Arts students will be actively involved in authentic mathematical experiences that
are both challenging and intellectually stimulating
provide meaningful cognitive and metacognitive gains and
nurture healthy and informed perceptions of mathematics mathematical ways of thinking and the ongoing impact of mathematics not only on STEM fields but also on the liberal arts and humanities

Brain Rules The brain seems to rely partly
on past experience in deciding how to learn new things
Make sure they understand what is new each time
Our senses evolved to work together
We learn best if we stimulate several senses at once
Patterns and Connections We are better at seeing
patterns and abstracting the meaning of an event than we are at recording detail
Emotional arousal helps the brain learn
So make it emotional
Memory and Brain Rules Most memories disappear
within minutes
How do we make sure it gets into long-term memory
Incorporate new information gradually
Repeat it in timed intervals
Brain RulesBabies are the model of how we learn
observation
hypothesis
experiment
conclusion
Darn Kids these days
This is not just about ldquokids these daysrdquo this research is decades old
Brains more wired for linear bursts than deep thinking (always on etc)

Our Vision
Mathematics for Liberal Arts students will be actively involved in authentic mathematical experiences that
are both challenging and intellectually stimulating
provide meaningful cognitive and metacognitive gains and
nurture healthy and informed perceptions of mathematics mathematical ways of thinking and the ongoing impact of mathematics not only on STEM fields but also on the liberal arts and humanities

Brain Rules The brain seems to rely partly
on past experience in deciding how to learn new things
Make sure they understand what is new each time
Our senses evolved to work together
We learn best if we stimulate several senses at once
Patterns and Connections We are better at seeing
patterns and abstracting the meaning of an event than we are at recording detail
Emotional arousal helps the brain learn
So make it emotional
Memory and Brain Rules Most memories disappear
within minutes
How do we make sure it gets into long-term memory
Incorporate new information gradually
Repeat it in timed intervals
Brain RulesBabies are the model of how we learn
observation
hypothesis
experiment
conclusion
Darn Kids these days
This is not just about ldquokids these daysrdquo this research is decades old
Brains more wired for linear bursts than deep thinking (always on etc)

Ever Heard This
ldquoOnce I know what to do itrsquos easy My trouble is knowing where to startrdquo
ldquoDonrsquot make me try to understand this just tell me what to dordquo
73
In the ldquoreal worldrdquohellip
1 Whose job is it to ldquounderstand the problemrdquo(Usually company officers and executives)
2 Whose job is it to ldquodevise a plan or strategyrdquo(Usually the managers and engineers)
74
In the ldquoreal worldrdquohellip
3 Whose job is it to ldquocarry out the planrdquo(Usually the assistants clerks and laborers)
4 Whose job is it to ldquolook backrdquo and see if a satisfactory outcome has been achieved(Usually the officers and executives again)
75
Who are the lowest paid
1 Company officers and executives
2 Managers and engineers
3 Assistants clerks and laborers
4 Company officers and executives
Who are most likely to be replaced by automation outsourcing or a computer1 Company officers or executives
2 Managers or engineers
3 Assistants clerks or laborers
4 Company officers or executives
77
So if we focus almost entirely on step 3 ldquocarry out the planrdquo what are we preparing our students for
78
A thorough knowledge of what skills techniques and procedures are possible is necessary especially to those who ldquodevise a planrdquo
But this is not sufficient
79
To fully prepare our students for a productive (and well paying) career we must emphasize all facets of problem solving

OTHER Important Tidbits Optional The use of FB is optional but I
always strongly recommend it For those who are FB-haters I tell them that they can create an account with their school email and only use it for this purpose Once in a blue moon I have someone who is adamantly against FB so I just tell them that its their responsibility to get info from a classmate or myself

Sometimes itrsquos necessary to consult an expert
Your skills do not improve by watching someone else play the

Ever Heard This
ldquoOnce I know what to do itrsquos easy My trouble is knowing where to startrdquo
ldquoDonrsquot make me try to understand this just tell me what to dordquo
73
In the ldquoreal worldrdquohellip
1 Whose job is it to ldquounderstand the problemrdquo(Usually company officers and executives)
2 Whose job is it to ldquodevise a plan or strategyrdquo(Usually the managers and engineers)
74
In the ldquoreal worldrdquohellip
3 Whose job is it to ldquocarry out the planrdquo(Usually the assistants clerks and laborers)
4 Whose job is it to ldquolook backrdquo and see if a satisfactory outcome has been achieved(Usually the officers and executives again)
75
Who are the lowest paid
1 Company officers and executives
2 Managers and engineers
3 Assistants clerks and laborers
4 Company officers and executives
Who are most likely to be replaced by automation outsourcing or a computer1 Company officers or executives
2 Managers or engineers
3 Assistants clerks or laborers
4 Company officers or executives
77
So if we focus almost entirely on step 3 ldquocarry out the planrdquo what are we preparing our students for
78
A thorough knowledge of what skills techniques and procedures are possible is necessary especially to those who ldquodevise a planrdquo
But this is not sufficient
79
To fully prepare our students for a productive (and well paying) career we must emphasize all facets of problem solving

on the use of this forum stated on the About section of the class FB page I warn them that any inappropriate use of the forum results in immediate removal from the group (although this has never been an issue)
OTHER Important Tidbits Optional The use of FB is optional but I
always strongly recommend it For those who are FB-haters I tell them that they can create an account with their school email and only use it for this purpose Once in a blue moon I have someone who is adamantly against FB so I just tell them that its their responsibility to get info from a classmate or myself

There are rules that must be followed
You must use the proper equipment
Your skills improve with regular practice
Sometimes itrsquos necessary to consult an expert
Your skills do not improve by watching someone else play the
game
Patience hellip
Persistence may be rewarded
Sometimes you have to calculate
You must be prepared to interpret the result of your
calculations
A good score can be very satisfying
It can be a social activity
Sometimes itrsquos fun

77
So if we focus almost entirely on step 3 ldquocarry out the planrdquo what are we preparing our students for
78
A thorough knowledge of what skills techniques and procedures are possible is necessary especially to those who ldquodevise a planrdquo
But this is not sufficient
79
To fully prepare our students for a productive (and well paying) career we must emphasize all facets of problem solving

Exercises vs Problems
ExercisePractice a rule or procedure
Factor this polynomial
Solve this equation
Find the distance between these two points

Ever Heard This
ldquoOnce I know what to do itrsquos easy My trouble is knowing where to startrdquo
ldquoDonrsquot make me try to understand this just tell me what to dordquo
73
In the ldquoreal worldrdquohellip
1 Whose job is it to ldquounderstand the problemrdquo(Usually company officers and executives)
2 Whose job is it to ldquodevise a plan or strategyrdquo(Usually the managers and engineers)
74
In the ldquoreal worldrdquohellip
3 Whose job is it to ldquocarry out the planrdquo(Usually the assistants clerks and laborers)
4 Whose job is it to ldquolook backrdquo and see if a satisfactory outcome has been achieved(Usually the officers and executives again)
75
Who are the lowest paid
1 Company officers and executives
2 Managers and engineers
3 Assistants clerks and laborers
4 Company officers and executives
Who are most likely to be replaced by automation outsourcing or a computer1 Company officers or executives
2 Managers or engineers
3 Assistants clerks or laborers
4 Company officers or executives
77
So if we focus almost entirely on step 3 ldquocarry out the planrdquo what are we preparing our students for
78
A thorough knowledge of what skills techniques and procedures are possible is necessary especially to those who ldquodevise a planrdquo
But this is not sufficient
79
To fully prepare our students for a productive (and well paying) career we must emphasize all facets of problem solving

Ever Heard This
ldquoOnce I know what to do itrsquos easy My trouble is knowing where to startrdquo
ldquoDonrsquot make me try to understand this just tell me what to dordquo
73
In the ldquoreal worldrdquohellip
1 Whose job is it to ldquounderstand the problemrdquo(Usually company officers and executives)
2 Whose job is it to ldquodevise a plan or strategyrdquo(Usually the managers and engineers)
74
In the ldquoreal worldrdquohellip
3 Whose job is it to ldquocarry out the planrdquo(Usually the assistants clerks and laborers)
4 Whose job is it to ldquolook backrdquo and see if a satisfactory outcome has been achieved(Usually the officers and executives again)
75
Who are the lowest paid
1 Company officers and executives
2 Managers and engineers
3 Assistants clerks and laborers
4 Company officers and executives
Who are most likely to be replaced by automation outsourcing or a computer1 Company officers or executives
2 Managers or engineers
3 Assistants clerks or laborers
4 Company officers or executives
77
So if we focus almost entirely on step 3 ldquocarry out the planrdquo what are we preparing our students for
78
A thorough knowledge of what skills techniques and procedures are possible is necessary especially to those who ldquodevise a planrdquo
But this is not sufficient
79
To fully prepare our students for a productive (and well paying) career we must emphasize all facets of problem solving

77
So if we focus almost entirely on step 3 ldquocarry out the planrdquo what are we preparing our students for
78
A thorough knowledge of what skills techniques and procedures are possible is necessary especially to those who ldquodevise a planrdquo
But this is not sufficient
79
To fully prepare our students for a productive (and well paying) career we must emphasize all facets of problem solving

Ever Heard This
ldquoOnce I know what to do itrsquos easy My trouble is knowing where to startrdquo
ldquoDonrsquot make me try to understand this just tell me what to dordquo

1 Whose job is it to ldquounderstand the problemrdquo(Usually company officers and executives)
2 Whose job is it to ldquodevise a plan or strategyrdquo(Usually the managers and engineers)
74
In the ldquoreal worldrdquohellip
3 Whose job is it to ldquocarry out the planrdquo(Usually the assistants clerks and laborers)
4 Whose job is it to ldquolook backrdquo and see if a satisfactory outcome has been achieved(Usually the officers and executives again)
75
Who are the lowest paid

4 Company officers and executives
Who are most likely to be replaced by automation outsourcing or a computer1 Company officers or executives

4 Company officers or executives
77
So if we focus almost entirely on step 3 ldquocarry out the planrdquo what are we preparing our students for
78
A thorough knowledge of what skills techniques and procedures are possible is necessary especially to those who ldquodevise a planrdquo
But this is not sufficient
79
To fully prepare our students for a productive (and well paying) career we must emphasize all facets of problem solving

OTHER Important Tidbits Policy I have a very clear written policy
on the use of this forum stated on the About section of the class FB page I warn them that any inappropriate use of the forum results in immediate removal from the group (although this has never been an issue)
OTHER Important Tidbits Optional The use of FB is optional but I
always strongly recommend it For those who are FB-haters I tell them that they can create an account with their school email and only use it for this purpose Once in a blue moon I have someone who is adamantly against FB so I just tell them that its their responsibility to get info from a classmate or myself

There are rules that must be followed
You must use the proper equipment
Your skills improve with regular practice
Sometimes itrsquos necessary to consult an expert
Your skills do not improve by watching someone else play the
game
Patience hellip
Persistence may be rewarded
Sometimes you have to calculate
You must be prepared to interpret the result of your
calculations
A good score can be very satisfying
It can be a social activity
Sometimes itrsquos fun
And now for something completely different hellip

Ever Heard This
ldquoOnce I know what to do itrsquos easy My trouble is knowing where to startrdquo
ldquoDonrsquot make me try to understand this just tell me what to dordquo
73
In the ldquoreal worldrdquohellip
1 Whose job is it to ldquounderstand the problemrdquo(Usually company officers and executives)
2 Whose job is it to ldquodevise a plan or strategyrdquo(Usually the managers and engineers)
74
In the ldquoreal worldrdquohellip
3 Whose job is it to ldquocarry out the planrdquo(Usually the assistants clerks and laborers)
4 Whose job is it to ldquolook backrdquo and see if a satisfactory outcome has been achieved(Usually the officers and executives again)
75
Who are the lowest paid
1 Company officers and executives
2 Managers and engineers
3 Assistants clerks and laborers
4 Company officers and executives
Who are most likely to be replaced by automation outsourcing or a computer1 Company officers or executives
2 Managers or engineers
3 Assistants clerks or laborers
4 Company officers or executives
77
So if we focus almost entirely on step 3 ldquocarry out the planrdquo what are we preparing our students for
78
A thorough knowledge of what skills techniques and procedures are possible is necessary especially to those who ldquodevise a planrdquo
But this is not sufficient
79
To fully prepare our students for a productive (and well paying) career we must emphasize all facets of problem solving

Ever Heard This
ldquoOnce I know what to do itrsquos easy My trouble is knowing where to startrdquo
ldquoDonrsquot make me try to understand this just tell me what to dordquo
73
In the ldquoreal worldrdquohellip
1 Whose job is it to ldquounderstand the problemrdquo(Usually company officers and executives)
2 Whose job is it to ldquodevise a plan or strategyrdquo(Usually the managers and engineers)
74
In the ldquoreal worldrdquohellip
3 Whose job is it to ldquocarry out the planrdquo(Usually the assistants clerks and laborers)
4 Whose job is it to ldquolook backrdquo and see if a satisfactory outcome has been achieved(Usually the officers and executives again)
75
Who are the lowest paid
1 Company officers and executives
2 Managers and engineers
3 Assistants clerks and laborers
4 Company officers and executives
Who are most likely to be replaced by automation outsourcing or a computer1 Company officers or executives
2 Managers or engineers
3 Assistants clerks or laborers
4 Company officers or executives
77
So if we focus almost entirely on step 3 ldquocarry out the planrdquo what are we preparing our students for
78
A thorough knowledge of what skills techniques and procedures are possible is necessary especially to those who ldquodevise a planrdquo
But this is not sufficient
79
To fully prepare our students for a productive (and well paying) career we must emphasize all facets of problem solving

Problem SolvingDONrsquoT Just Tell Them What to Do

Exercises vs Problems
ExercisePractice a rule or procedure
Factor this polynomial
Solve this equation
Find the distance between these two points
Differentiate these functions

Ever Heard This
ldquoOnce I know what to do itrsquos easy My trouble is knowing where to startrdquo
ldquoDonrsquot make me try to understand this just tell me what to dordquo
73
In the ldquoreal worldrdquohellip
1 Whose job is it to ldquounderstand the problemrdquo(Usually company officers and executives)
2 Whose job is it to ldquodevise a plan or strategyrdquo(Usually the managers and engineers)
74
In the ldquoreal worldrdquohellip
3 Whose job is it to ldquocarry out the planrdquo(Usually the assistants clerks and laborers)
4 Whose job is it to ldquolook backrdquo and see if a satisfactory outcome has been achieved(Usually the officers and executives again)
75
Who are the lowest paid
1 Company officers and executives
2 Managers and engineers
3 Assistants clerks and laborers
4 Company officers and executives
Who are most likely to be replaced by automation outsourcing or a computer1 Company officers or executives
2 Managers or engineers
3 Assistants clerks or laborers
4 Company officers or executives
77
So if we focus almost entirely on step 3 ldquocarry out the planrdquo what are we preparing our students for
78
A thorough knowledge of what skills techniques and procedures are possible is necessary especially to those who ldquodevise a planrdquo
But this is not sufficient
79
To fully prepare our students for a productive (and well paying) career we must emphasize all facets of problem solving

There are rules that must be followed
You must use the proper equipment
Your skills improve with regular practice
Sometimes itrsquos necessary to consult an expert
Your skills do not improve by watching someone else play the
game
Patience hellip
Persistence may be rewarded
Sometimes you have to calculate
You must be prepared to interpret the result of your
calculations
A good score can be very satisfying
It can be a social activity
Sometimes itrsquos fun

Ever Heard This
ldquoOnce I know what to do itrsquos easy My trouble is knowing where to startrdquo
ldquoDonrsquot make me try to understand this just tell me what to dordquo
73
In the ldquoreal worldrdquohellip
1 Whose job is it to ldquounderstand the problemrdquo(Usually company officers and executives)
2 Whose job is it to ldquodevise a plan or strategyrdquo(Usually the managers and engineers)
74
In the ldquoreal worldrdquohellip
3 Whose job is it to ldquocarry out the planrdquo(Usually the assistants clerks and laborers)
4 Whose job is it to ldquolook backrdquo and see if a satisfactory outcome has been achieved(Usually the officers and executives again)
75
Who are the lowest paid
1 Company officers and executives
2 Managers and engineers
3 Assistants clerks and laborers
4 Company officers and executives
Who are most likely to be replaced by automation outsourcing or a computer1 Company officers or executives
2 Managers or engineers
3 Assistants clerks or laborers
4 Company officers or executives
77
So if we focus almost entirely on step 3 ldquocarry out the planrdquo what are we preparing our students for
78
A thorough knowledge of what skills techniques and procedures are possible is necessary especially to those who ldquodevise a planrdquo
But this is not sufficient
79
To fully prepare our students for a productive (and well paying) career we must emphasize all facets of problem solving

OTHER Important Tidbits Policy I have a very clear written policy
on the use of this forum stated on the About section of the class FB page I warn them that any inappropriate use of the forum results in immediate removal from the group (although this has never been an issue)
OTHER Important Tidbits Optional The use of FB is optional but I
always strongly recommend it For those who are FB-haters I tell them that they can create an account with their school email and only use it for this purpose Once in a blue moon I have someone who is adamantly against FB so I just tell them that its their responsibility to get info from a classmate or myself

There are rules that must be followed
You must use the proper equipment
Your skills improve with regular practice
Sometimes itrsquos necessary to consult an expert
Your skills do not improve by watching someone else play the
game
Patience hellip
Persistence may be rewarded
Sometimes you have to calculate
You must be prepared to interpret the result of your
calculations
A good score can be very satisfying
It can be a social activity

Exercises vs Problems
ExercisePractice a rule or procedure
Factor this polynomial
Solve this equation
Find the distance between these two points
Differentiate these functions

ProblemA problem usually requires more thinking and analysis In most cases there is no formula that immediately gives the answer
Find a point on a given line which is equidistant from two given points

2 Whose job is it to ldquodevise a plan or strategyrdquo(Usually the managers and engineers)
74
In the ldquoreal worldrdquohellip
3 Whose job is it to ldquocarry out the planrdquo(Usually the assistants clerks and laborers)
4 Whose job is it to ldquolook backrdquo and see if a satisfactory outcome has been achieved(Usually the officers and executives again)
75
Who are the lowest paid

This project is based upon work currently supported by the National Science Foundation under NSF1225915 (TUES) and previously supported by NSF0836943 (CCLI) and a gift
from Mr Harry Lucas
Our Vision
Mathematics for Liberal Arts students will be actively involved in authentic mathematical experiences that
are both challenging and intellectually stimulating
provide meaningful cognitive and metacognitive gains and
nurture healthy and informed perceptions of mathematics mathematical ways of thinking and the ongoing impact of mathematics not only on STEM fields but also on the liberal arts and humanities

There are rules that must be followed
You must use the proper equipment
Your skills improve with regular practice
Sometimes itrsquos necessary to consult an expert
Your skills do not improve by watching someone else play the
game
Patience hellip
Persistence may be rewarded
Sometimes you have to calculate
You must be prepared to interpret the result of your
calculations
A good score can be very satisfying

Ever Heard This
ldquoOnce I know what to do itrsquos easy My trouble is knowing where to startrdquo
ldquoDonrsquot make me try to understand this just tell me what to dordquo
73
In the ldquoreal worldrdquohellip
1 Whose job is it to ldquounderstand the problemrdquo(Usually company officers and executives)
2 Whose job is it to ldquodevise a plan or strategyrdquo(Usually the managers and engineers)
74
In the ldquoreal worldrdquohellip
3 Whose job is it to ldquocarry out the planrdquo(Usually the assistants clerks and laborers)
4 Whose job is it to ldquolook backrdquo and see if a satisfactory outcome has been achieved(Usually the officers and executives again)
75
Who are the lowest paid
1 Company officers and executives
2 Managers and engineers
3 Assistants clerks and laborers
4 Company officers and executives
Who are most likely to be replaced by automation outsourcing or a computer1 Company officers or executives
2 Managers or engineers
3 Assistants clerks or laborers
4 Company officers or executives
77
So if we focus almost entirely on step 3 ldquocarry out the planrdquo what are we preparing our students for
78
A thorough knowledge of what skills techniques and procedures are possible is necessary especially to those who ldquodevise a planrdquo
But this is not sufficient
79
To fully prepare our students for a productive (and well paying) career we must emphasize all facets of problem solving

3 Whose job is it to ldquocarry out the planrdquo(Usually the assistants clerks and laborers)
4 Whose job is it to ldquolook backrdquo and see if a satisfactory outcome has been achieved(Usually the officers and executives again)
75
Who are the lowest paid

Who are most likely to be replaced by automation outsourcing or a computer1 Company officers or executives
2 Managers or engineers
3 Assistants clerks or laborers
4 Company officers or executives
77
So if we focus almost entirely on step 3 ldquocarry out the planrdquo what are we preparing our students for
78
A thorough knowledge of what skills techniques and procedures are possible is necessary especially to those who ldquodevise a planrdquo
But this is not sufficient
79
To fully prepare our students for a productive (and well paying) career we must emphasize all facets of problem solving

Mathematics for Liberal Arts students will be actively involved in authentic mathematical experiences that
are both challenging and intellectually stimulating
provide meaningful cognitive and metacognitive gains and
nurture healthy and informed perceptions of mathematics mathematical ways of thinking and the ongoing impact of mathematics not only on STEM fields but also on the liberal arts and humanities

3 Whose job is it to ldquocarry out the planrdquo(Usually the assistants clerks and laborers)
4 Whose job is it to ldquolook backrdquo and see if a satisfactory outcome has been achieved(Usually the officers and executives again)
75
Who are the lowest paid

3 Assistants clerks and laborers
4 Company officers and executives
Who are most likely to be replaced by automation outsourcing or a computer1 Company officers or executives
2 Managers or engineers
3 Assistants clerks or laborers
4 Company officers or executives
77
So if we focus almost entirely on step 3 ldquocarry out the planrdquo what are we preparing our students for
78
A thorough knowledge of what skills techniques and procedures are possible is necessary especially to those who ldquodevise a planrdquo
But this is not sufficient
79
To fully prepare our students for a productive (and well paying) career we must emphasize all facets of problem solving

Ever Heard This
ldquoOnce I know what to do itrsquos easy My trouble is knowing where to startrdquo
ldquoDonrsquot make me try to understand this just tell me what to dordquo
73
In the ldquoreal worldrdquohellip
1 Whose job is it to ldquounderstand the problemrdquo(Usually company officers and executives)
2 Whose job is it to ldquodevise a plan or strategyrdquo(Usually the managers and engineers)
74
In the ldquoreal worldrdquohellip
3 Whose job is it to ldquocarry out the planrdquo(Usually the assistants clerks and laborers)
4 Whose job is it to ldquolook backrdquo and see if a satisfactory outcome has been achieved(Usually the officers and executives again)
75
Who are the lowest paid
1 Company officers and executives
2 Managers and engineers
3 Assistants clerks and laborers
4 Company officers and executives
Who are most likely to be replaced by automation outsourcing or a computer1 Company officers or executives
2 Managers or engineers
3 Assistants clerks or laborers
4 Company officers or executives
77
So if we focus almost entirely on step 3 ldquocarry out the planrdquo what are we preparing our students for
78
A thorough knowledge of what skills techniques and procedures are possible is necessary especially to those who ldquodevise a planrdquo
But this is not sufficient
79
To fully prepare our students for a productive (and well paying) career we must emphasize all facets of problem solving

Your skills improve with regular practice
Sometimes itrsquos necessary to consult an expert
Your skills do not improve by watching someone else play the

Our Vision
Mathematics for Liberal Arts students will be actively involved in authentic mathematical experiences that
are both challenging and intellectually stimulating
provide meaningful cognitive and metacognitive gains and
nurture healthy and informed perceptions of mathematics mathematical ways of thinking and the ongoing impact of mathematics not only on STEM fields but also on the liberal arts and humanities

Who are most likely to be replaced by automation outsourcing or a computer1 Company officers or executives

77
So if we focus almost entirely on step 3 ldquocarry out the planrdquo what are we preparing our students for
78
A thorough knowledge of what skills techniques and procedures are possible is necessary especially to those who ldquodevise a planrdquo
But this is not sufficient
79
To fully prepare our students for a productive (and well paying) career we must emphasize all facets of problem solving

There are rules that must be followed
You must use the proper equipment
Your skills improve with regular practice
Sometimes itrsquos necessary to consult an expert
Your skills do not improve by watching someone else play the
game
Patience hellip
Persistence may be rewarded
Sometimes you have to calculate

Our Vision
Mathematics for Liberal Arts students will be actively involved in authentic mathematical experiences that
are both challenging and intellectually stimulating
provide meaningful cognitive and metacognitive gains and
nurture healthy and informed perceptions of mathematics mathematical ways of thinking and the ongoing impact of mathematics not only on STEM fields but also on the liberal arts and humanities

In the ldquoreal worldrdquohellip
3 Whose job is it to ldquocarry out the planrdquo(Usually the assistants clerks and laborers)
4 Whose job is it to ldquolook backrdquo and see if a satisfactory outcome has been achieved(Usually the officers and executives again)

Who are the lowest paid
1 Company officers and executives
2 Managers and engineers
3 Assistants clerks and laborers
4 Company officers and executives
Who are most likely to be replaced by automation outsourcing or a computer1 Company officers or executives

4 Company officers or executives
77
So if we focus almost entirely on step 3 ldquocarry out the planrdquo what are we preparing our students for
78
A thorough knowledge of what skills techniques and procedures are possible is necessary especially to those who ldquodevise a planrdquo
But this is not sufficient
79
To fully prepare our students for a productive (and well paying) career we must emphasize all facets of problem solving

There are rules that must be followed
You must use the proper equipment
Your skills improve with regular practice
Sometimes itrsquos necessary to consult an expert
Your skills do not improve by watching someone else play the
game
Patience hellip
Persistence may be rewarded
Sometimes you have to calculate
You must be prepared to interpret the result of your
calculations
A good score can be very satisfying
It can be a social activity
Sometimes itrsquos fun

Our Vision
Mathematics for Liberal Arts students will be actively involved in authentic mathematical experiences that
are both challenging and intellectually stimulating
provide meaningful cognitive and metacognitive gains and
nurture healthy and informed perceptions of mathematics mathematical ways of thinking and the ongoing impact of mathematics not only on STEM fields but also on the liberal arts and humanities

A thorough knowledge of what skills techniques and procedures are possible is necessary especially to those who ldquodevise a planrdquo

OTHER Important Tidbits Optional The use of FB is optional but I
always strongly recommend it For those who are FB-haters I tell them that they can create an account with their school email and only use it for this purpose Once in a blue moon I have someone who is adamantly against FB so I just tell them that its their responsibility to get info from a classmate or myself

There are rules that must be followed
You must use the proper equipment
Your skills improve with regular practice
Sometimes itrsquos necessary to consult an expert
Your skills do not improve by watching someone else play the
game
Patience hellip
Persistence may be rewarded
Sometimes you have to calculate
You must be prepared to interpret the result of your
calculations
A good score can be very satisfying
It can be a social activity
Sometimes itrsquos fun
And now for something completely different hellip

There are rules that must be followed
You must use the proper equipment
Your skills improve with regular practice
Sometimes itrsquos necessary to consult an expert
Your skills do not improve by watching someone else play the
game
Patience hellip
Persistence may be rewarded
Sometimes you have to calculate
You must be prepared to interpret the result of your
calculations
A good score can be very satisfying
It can be a social activity
Sometimes itrsquos fun
And now for something completely different hellip

eightA Nice belt
Q How does a cow add
A It adds one udder to an udder
Q Why is the snake so good at math
A Because hersquos an adder
Even Worse Math JokesQ Why is the math book so upsetA Because it has lots of problems
Q What did the math plan grow
A Square roots

There are rules that must be followed
You must use the proper equipment
Your skills improve with regular practice
Sometimes itrsquos necessary to consult an expert
Your skills do not improve by watching someone else play the
game
Patience hellip
Persistence may be rewarded
Sometimes you have to calculate
You must be prepared to interpret the result of your
calculations
A good score can be very satisfying
It can be a social activity

There are rules that must be followed
You must use the proper equipment
Your skills improve with regular practice
Sometimes itrsquos necessary to consult an expert
Your skills do not improve by watching someone else play the
game
Patience hellip
Persistence may be rewarded
Sometimes you have to calculate
You must be prepared to interpret the result of your
calculations
A good score can be very satisfying
It can be a social activity
Sometimes itrsquos fun

There are rules that must be followed
You must use the proper equipment
Your skills improve with regular practice
Sometimes itrsquos necessary to consult an expert
Your skills do not improve by watching someone else play the
game
Patience hellip
Persistence may be rewarded
Sometimes you have to calculate
You must be prepared to interpret the result of your

A good score can be very satisfying

Your skills improve with regular practice
Sometimes itrsquos necessary to consult an expert
Your skills do not improve by watching someone else play the
game
Patience hellip
Persistence may be rewarded
Sometimes you have to calculate
You must be prepared to interpret the result of your

A good score can be very satisfying

OTHER Important Tidbits Policy I have a very clear written policy
on the use of this forum stated on the About section of the class FB page I warn them that any inappropriate use of the forum results in immediate removal from the group (although this has never been an issue)
OTHER Important Tidbits Optional The use of FB is optional but I
always strongly recommend it For those who are FB-haters I tell them that they can create an account with their school email and only use it for this purpose Once in a blue moon I have someone who is adamantly against FB so I just tell them that its their responsibility to get info from a classmate or myself

Your skills do not improve by watching someone else play the

Our Vision
Mathematics for Liberal Arts students will be actively involved in authentic mathematical experiences that
are both challenging and intellectually stimulating
provide meaningful cognitive and metacognitive gains and
nurture healthy and informed perceptions of mathematics mathematical ways of thinking and the ongoing impact of mathematics not only on STEM fields but also on the liberal arts and humanities
