  • Whats the big deal?

    Cant any good elementary school teacher teach children elementary school mathematics?

  • What is so difficult about the preparation of mathematics teachers?Our universities do not adequately prepare mathematics teachers for their mathematical needs in the school classroom. Most teachers cannot bridge the gap between what we teach them in the undergraduate curriculum and what they teach in schools.We have not done nearly enough to help teachers understand the essential characteristics of mathematics: its precision, the ubiquity of logical reasoning, and its coherence as a discipline.The goal is not to help future teachers learn mathematics but to make them better teachers. H. Wu

  • What is so difficult .?For most future elementary school teachers the level of need is so basic, that what a mathematician might envision as an appropriate course is likely to be hopelessly over the heads of most of the students.

    Forget what seems like a good thing to do in some idealized world, and get real: adapt the courses to the actual level and needs of the students.

    The mathematics taught should be connected as directly as possible to the classroom. This is more important, the more abstract and powerful the principles are. Teachers cannot be expected to make the links on their own.

  • Get teacher candidates to believe, that mathematics is something you think about - that validity comes from inner conviction that things make sense, that mathematical situations can be reasoned about on the basis of a few basic principles.

    The goal is to have them develop some flexibility in their thinking, to be able to reason about elementary mathematics.Roger Howe

  • Adding it Up argues that mathematical proficiency has five strands:Conceptual understandingComprehension of mathematical concepts, operations, and relationsProcedural fluencySkill in carrying out procedures flexibly, accurately, efficiently, and appropriately

  • mathematical proficiency Strategic competenceAbility to formulate, represent, and solve mathematical problemsAdaptive reasoningCapacity for logical thought, reflection, explanation, and justificationProductive dispositionHabitual inclination to see mathematics as sensible, useful, worthwhile, coupled with a belief in diligence and ones on efficacy.

  • Educating Teachers of Science, Mathematics, and TechnologyNew Practices for the New Millennium

    A report of the National Research CouncilsCommittee on Science and Mathematics Teacher Preparation

  • Educating Teachers argues:1) Many teachers are not adequately prepared to teach science and mathematics, in ways that bolster student learning and achievement. 2) The preparation of teachers does not meet the needs of the modern classroom.3) Professional development for teachers may do little to enhance teachers content knowledge or the techniques and skills they need to teach science and mathematics effectively.

    and recommends:a new partnership between K-12 schools and the higher education community designed to ensure high-quality teacher education and professional development for teachers.

  • The Mathematical Education of TeachersIs guided by two general themes:

    the intellectual substance in school mathematics; and

    the special nature of the mathematical knowledge needed for teaching.

  • The MET recommends:Prospective teachers need mathematics courses that develop a deep understanding of the mathematics they will teach.Prospective elementary grade teachers (K-4) should take at least 9 semester-hours on fundamental ideas of elementary school mathematics.

  • Mathematics courses should focus on a thorough development of basic mathematical ideas. develop careful reasoning and mathematical common sense in analyzing conceptual relationships and in solving problems. develop the habits of mind of a mathematical thinker and demonstrate flexible, interactive styles of teaching.

  • The mathematical education of teachers should be based onpartnerships between mathematics and mathematics education faculty.collaboration between mathematics faculty and school mathematics teachers.

  • The Math Matters VisionCreate a mathematician mathematics educator partnership with the goal of improving the mathematics education of future elementary school teachersLink field experiences, pedagogy and mathematics instruction Create math classes that are both accessible and useful for future elementary school teachers

  • MATH MATTERS Timeline Project began 01/01/2000 with NSF support.AY 2000/2001, first Math Matters cohort (16 students) participated in a year-long, 18-hour block of courses. Each semester had a math class, a pedagogy class, and a field experience.Significant progress in learning mathematics and in developing a positive attitude towards teaching mathSignificant growth in potential to be an outstanding teacherStrong bonding between students and faculty

  • MATH MATTERS Timeline Math Matters was repeated with a second cohort (16 students) during AY2001/2002Findings similar to first cohort AY 2002/2003 Two experiments with a one-semester, 12 hour block of courses (28 students, 19 students)Fall 2003 The Mathematics Semester beginsCurrent program is a one-semester, 10-hour, math, pedagogy, & field experience program.

  • Barriers to a Successful Partnership Math expectations seem to overwhelm students in Elementary EducationStudent evaluations critical of math facultyType of Course Faculty GPA#StudentsHonors class 3.20 1,367All faculty courses 3.0416,693Large Lectures2.88 6,060Education Majors2.48 726

  • Comments from a math class for elementary school teachers: (the course GPA was 2.93)This wasn't a course where we learn to teach math. Why do we have to explain our answers.I did not like getting a 0 on problems that I attempted. I could have just of left the problem blank then. tests are invalid. They ask questions we have never seen before. It would help if we knew more about the questions on the exams - If examples in class were used on the exams.

  • Comments from a math class for elementary school teachers: (the course GPA was 2.93)Her way of assessing her class aren't fair.

    there was never partial credit. When 20 people drop a class ... there is an obvious problem. [Note: Only 3 of 33 students dropped the class.]

    Test materials were not consistent or reliable with the material covered in class. Grading was very biased.

  • Comments from a Contemporary Math class (She) does a good job making the subject matter interesting. She always seems very enthusiastic about the class and and actual work. More teachers should be like her.(She) is a great teacher with a love for her subject that becomes addictive. It has really been my lucky pick to have gotten her as an instructor.(She) made the class exciting. It is obvious she enjoys math and teaching. She was always clear in her expectations and directions.

  • Comments from a Contemporary Math classThis was a very useful class. I also think that (she) is a great teacher.(She) was one of the best teachers I have had here at UNL. She was always available for questions!This was a very good class. I failed the class last semester with a different teacher but (she) did a much better job and I am doing great in the class!

  • What is the typical ability of a future elementary school teacher at UNL?How would our students do on two famous problems?1) How do you solve the problem 1 / ?Imagine you are teaching division with fractions. Teachers need to write story-problems to show the application of some particular piece of content. What would be a good problem for 1/ ?

  • In Knowing and Teaching Elementary Mathematics this question was asked of 23 US teachers. Liping Ma reports:9 of 23 US teachers could perform the calculation using a correct algorithm and provide a complete answer.Only 1 of 23 US teachers could create a valid story problem for the computation. It was pedagogically problematic in that the answer involved 3 children.

  • Surely our teachers and future teachers can do better? In the summer of 2002, Ruth interviewed a group of Lincoln Public School teachers who were participating in a summer workshop Jim had organized.14 of 17 (elem and middle level) LPS teachers tested could perform the division of fractions algorithm correctly.Only 4 out of 17 could create a valid word problem. 3 of these 4 were middle school teachersWe also asked our students to work this problem.AlgorithmWord ProblemFall 2003 Students23 of 25 8 of 25Year 2 (early in sem)10 of 16 6 of 16Year 1 (mid year)12 of 1610 of 16

  • Sample solutions from our class last Fall:Among the better answers we received were these:Bobby only ran the distance that he hoped to run in practice. If Bobby ran 1 miles and that was only of the amount he wanted to run, what was his original goal?Bill is running a race that is 1 miles. The director of the race wants to put markers every mile. How many markers does he need?

  • Sample solutions from our class this Fall:Other solutions included the following:Suzie has one and pies. Ed is hungry and decides he is going to eat of what Suzie has. When Ed is finished, how many halves of the pie does Suzie have left?Jane has 7 quarters. She wants to put the quarters into groups of 2 quarters each. How many groups can she make?You have 1 of a pie! That is not enough. You want more of what they started with. How much more will you need? Mom baked 2 pies and divided the pies in quarters. After giving away one slice shes left with 1 pies. She then divides each left over piece into halves. How many pieces does she have now?

  • Perimeter and Area2) A student comes to class excited. She tells you she has figured out a theory you never told the class. She says she has discovered that as the perimeter of a closed figure increases, the area also increases. She shows you a picture to prove what she is doing.

    The square is 4 by 4Perimeter = 16Area = 16

    The rectangle is 4 by 8Perimeter = 24Area = 32

  • The first day of our Fall 2002 class, we asked our (geometry) students to respond to the area perimeter question. 24 of 32 future elementary teachers believed the childs theory was correct and indicated that they would congratulate the child.Eight of 32 future elementary teachers questioned the child's theory about area and perimeter. Only six of the eight explained that the theory was definitely not true.
