1.1 The Teaching Approach as the Result of Lesson Study
Stigler and Hiebert [1999] explained the Japanese teaching approach as follows:
Teachers begin by presenting students with a mathematics problem employing principles they have not yet learned. They then work alone or in small groups to devise a solution. After a few minutes, students are called on to present their answers; the whole class works through the problems and solutions, uncovering the related mathematical concepts and reasoning.
