Teaching less can mean learning more. Students struggle with the problem. Various students present ideas or solutions to the class. Class discusses the various solution methods. The teacher summarizes the class' conclusions.
Students practice similar problems.
Teacher solves example problems with class. Students practice on their own while the teacher assists individual students. Students are actively involved in solution approaches and formulation with alternative solution ideas discussed extensively. These are not, however, student directed situations. The classrooms are very teacher directed.
