Objective Promote Mathematical conflict... ….by any means necessary. Resources and links at emergentmath.wordpress.com
A CONFLICT-CENTRIC APPROACH TO MATHEMATICS Malcolm Swan – Conflict and Discussion Approach to Mathematics
Evidence of “good” mathematical conflict. Students talking about math. A debate about why / what answer? Little teacher direction Relevance – being able to make connections between everyday experience Task offers multiple possible solutions Task links several mathematical concepts All student levels are engaged Emphasis on process Arguing different methods about solving the problem. Evidence of “bad” (or no) mathematical conflict. Sleeping Answers are on the board Notetaking No surprises Students are quiet little islands Computations Teachers’ throat hurts – they’re doing all the work Lack of words / word walls Students not helping each other No questions
