One way to teach and assess students understanding of math concepts and procedures is to create a cognitive conflict. Here is one way you can create cognitive conflict in solving inequalities: To solve the inequality x – 7 > 5, the process usually involve adding 7 to both sides of the inequality. There is no change in the inequality sign since the same quantity is added on both sides. x – 7 > 5 x – 7 + 7 > [...]

According to Piaget, knowledge is constructed when a learner encounters input from the environment and incorporates the new experiences to his/her existing schemes and mental structures (assimilation). When this new assimilated information conflicts with previously formed mental structures, the result is called disequilibrium – a cognitive conflict. This state of disequilibrium motivates the learner to seek equilibrium. The cognitive conflict approach to teaching is based on this assumption – that learners will seek this equilibrium. Cognitive conflict approach to teaching [...]
