  2. Alaska is an island?

  3. Why is it hotter in the summer? Is it because we are closer to the sun?

  4. Honey I shrunk the airplane!

  5. Misconceptions in Math An error in mathematics can be the result of • Not being careful enough – the student knows the idea, but just did not execute it correctly this time • A fundamental misunderstanding of the mathematical content, symbol or process

  6. Misconception (definition) Certain conceptual relations that are acquired may be inappropriate within a certain context. We terms such relations as "misconceptions." A misconception does not exist independently, but is contingent upon a certain existing conceptual framework. Misconceptions can change or disappear with the framework changes

  7. Example 1 Example 1: Simplify:

  9. Terms and factors • From the text our campus currently uses • Factors are two or more signed numbers, variables or expressions being multiplied • A term is a signed number, variable or expression begin added or subtracted

  10. Example 2 • Example 2: Solve

  24. Helping Students overcome Misconceptions • Most research suggests that we should fundamentally change the way we teach math and what we teach, that this would result in better conceptual understanding of the material BUT…..

  25. Helping Students overcome misconceptions • There may be political or structural reasons at your campus that makes it hard for you to do this • Change is slow (sometimes painfully ) on college campuses and systems • What can you do in the meantime? • Help identify misconceptions and the student thinking behind them
