Today’s Focus…Today’s mathematics requires more than getting the answer. We must… expand our understanding of

various questioning processes. develop an understanding of

the nature and function of questions related to increasing mathematical content knowledge

Page 3: NUMBERS Mathematics Professional Development © NUMBERS MPD tt

Today’s Focus…

learn to write effective questions self assess questions become aware of research in

thinking, metacognition, and higher-order cognitive processing

Purposes of questioning strategies for instructors…

They help you to: effectively plan class participation activities, design homework assignments, write exams, and match your goals or objectives for

an assignment with the actual components of the assignment.

You have 10 minutes.

Page 30: NUMBERS Mathematics Professional Development © NUMBERS MPD tt

Crafting an Effective Question-Task 1: page 4

Ask yourself.... Is the question directly related to a curriculum

objective? Is the question expressed as clearly, concisely,

and as unambiguously as possible? Does the question actively engage learners'

mental energies? Does the question generate critical thought? …

Page 31: NUMBERS Mathematics Professional Development © NUMBERS MPD tt

Task 2: Think-Pair-Share…page 5

With a partner-1. Identify and evaluate each question you

have written according to Blooms level.

Page 32: NUMBERS Mathematics Professional Development © NUMBERS MPD tt

Bloom’s Levels

Level 1: Knowledge Level 2: Comprehension Level 3: Application Level 4: Analysis Level 5: Synthesis Level 6: Evaluation

Page 33: NUMBERS Mathematics Professional Development © NUMBERS MPD tt

The main value of the Taxonomy is twofold: (1) it can stimulate teachers to help students acquire skills at all of these various levels, laying the proper foundation for higher levels by first assuring mastery of lower-level objectives; and (2) it provides a basis for developing measurement strategies to assess student performance at all these levels of learning.

Page 34: NUMBERS Mathematics Professional Development © NUMBERS MPD tt

By writing objectives and planning lessons with questions at the appropriate levels, you should be able to develop both objectives and assessment strategies that cover the full range of expectations within each TEK’s Student Expectation you will teach.

Page 35: NUMBERS Mathematics Professional Development © NUMBERS MPD tt

Convergent thinking questions are those which represent the analysis and integration of given or remembered information. Theylead you to an expected end result or answer.

Page 36: NUMBERS Mathematics Professional Development © NUMBERS MPD tt

Divergent

Divergent thinking questions are those which represent intellectual operations wherein you are free to generate independently your ownideas, or to take a new direction or perspective on a given topic.

Page 37: NUMBERS Mathematics Professional Development © NUMBERS MPD tt

Task 4: Think-Pair-Share…

Are some of your questions convergent?

Are others divergent?

Page 38: NUMBERS Mathematics Professional Development © NUMBERS MPD tt

Task 5:

Are your questions closed or opened?

The most important questions of all arethose asked by students as they try to make sense out of data and information. These are the

questions which enable students to Make Up Their Own Minds.

Page 65: NUMBERS Mathematics Professional Development © NUMBERS MPD tt

Social values are revealed through questioning

who can learn and who can teach

learning flows only from a teacher

or whether it can come from other students.

Page 66: NUMBERS Mathematics Professional Development © NUMBERS MPD tt

Create the climate for inquiry… How do teachers respond to the answers

their questions provoke? "uh-huh“, “that’s right”, “good” responses can

stop inquiry dead in its tracks. In place of such dead-end situations, you may

pursue an investigation in which simple factual inquiries give way to increasingly interpretive questions until new insights emerge.

Keep questions alive through long stretches of time, coming back to them days, even weeks, after they have first been asked.

Page 67: NUMBERS Mathematics Professional Development © NUMBERS MPD tt

Closing thoughts…

What new insights have you gained? What will you implement

immediately? What has been validated? What will you differently as a result of this training?

Page 68: NUMBERS Mathematics Professional Development © NUMBERS MPD tt

Ask a man a question and he inquiresfor a day; teach a man to question andhe inquires for life. Adapted from an old Chinese proverb

Page 69: NUMBERS Mathematics Professional Development © NUMBERS MPD tt

Remember… There’s More to Questioning than simply Asking!
