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

One thing that became clear – a lightbulb moment
One thing that you want to make sure not to forget that you learned today
One thing that could be made better
One thing you still have a question about
