Powerful tasks: A contribution to a high level of acting and reflecting in mathematics instruction

Abstract

Mathematics instruction contains two conflicting demands: on the one hand, the demand for economical efficiency and for well-developed “motorways” and, on the other hand, the demand that pupils should investigate and discover for themselves and have the freedom to “pave” their own ways. It is argued that tasks with a certain richness and quality offer some steps towards a constructive handling of this dilemma. The author tries to develop some properties of powerful tasks and to sketch the structure and philosophy of one concrete system of powerful tasks for the concept of angle. The main part of this paper presents seven examples of powerful tasks: five from the system of tasks and two with regard to pupils' working with 2-D-graphic systems. The construction of powerful tasks is viewed as a valuable contribution to bringing the theory and practice of mathematics education closer together.
