What distinguishes a misconception from a mistake or misapplication is the root of the error; it is a student’s understanding of the concept or relationship that is incomplete. In other words, it is a conceptual misunderstanding, not an error in calculation or notation.

Misconceptions Are Part of the Learning Process

“. . . erroneous understandings are termed

alternative conceptions or misconceptions (or

intuitive theories). Alternative conceptions

(misconceptions) are not unusual. In fact, they are

a normal part of the learning process.”

(Lucariello, J., & Naff, D., 2014)

The Mathematical Practices Are All about LEARNING WITH UNDERSTANDING

Mathematically proficient students . . .

Make sense of problems and perseverein solving them.

Reason abstractly and quantitatively.

Construct viable arguments and critiquethe reasoning of others.

Model with mathematics.

Use appropriate tools strategically.

Attend to precision.

Look for and make use of structure.

Look for and express regularity in repeated reasoning.

• Mathematics ability is primarily a function of opportunity, experience, and effort—not innate intelligence. • All students think mathematically.• Effective mathematics teaching cultivates students’ mathematical identities.

Things Adults Do/Say That Create or Reinforce Students’ Misconceptions: EQUAL SIGN

Two strategies to reinforce the correct meaning of the equal sign:

A. Placing the missing expression to the left rather than the right

of the equal sign (e.g., ____ = 3 x 7).

B. Posing True/False statements that students must evaluate and

explain. For example: True or False? 3 x 7 = 7 + 7 + 7

For early learners, it is natural and common to read a number like 14 as “one four.”

What is the conceptual issue here?

Counting past 10 requires learners to understand place value. Reading 14 as “one four” tells us that there is not a good understanding of place value.

What sort of supports will help students to revise their understanding?

➢ Similar to what is done with early versions of a writing assignment in English or history classes, students’ rough draft thinking in mathematics offers a place to begin exploring, sense making, and revising their understanding.

➢ Such an approach communicates to students that learning mathematics is a generative process of developing, refining, and extending understanding rather than a static state of knowing or not knowing.

validate–that pupil’s attempts to join in

• Look for and value students’ ideas and assetsrather than seeing deficits.

• Look for ways to invite students into mathematics rather than diminishing their mathematical identities.

• Look for students’ brilliance rather than seeing the results of the failure to recognize and value this!
