AME-SMS Conference 2012 Secondary

  1. 1. Parallel Lecture strategies to incorporate reflection in the mathematics classroomYe a p B a n H a r  M a r s h a l l C a v e n d i s h I n s t i t u t e  P a t h l i g h t S c h o o lSlides are available at www.banhar.blogspot.com
  2. 2. Without reflection, learning ends"short of the re-organizationof thinking that deep learningrequires" (Ewell, 1997). Synopsis This lecture includes some examples of how teachers can use strategies to encourage reflection in mathematics lessons. The examples covers lessons which are more teacher-centric such as lectures as well as lessons which are more student-centric such as group work.
