In mathematics dialogic teaching can also be used to discover/challenge misconceptions, build new concepts where no current concept exists and aid pupils with problem solving.
Think about the following question. it relates to teaching pupils about representative sampling
Maths homework is set 3 times a week. A pupil does the homework each time it is set. The homework is marked in class. Then, just once, the pupil forgets to do the homework. This time the teacher collects the books then marks them him/herself. As the pupil has not done the homework a mark of zero is recorded. What deductions might the teacher make? Is this fair?
When this question is used in a lesson is this?
discovering challenging misconceptions
building new concepts where no current concept exists
aiding pupils with problem solving?
