A Learning Environment for Solution-based Problem-Posing in Multi-Digit Subtraction

Abstract

In this paper, we describe developing and evaluation of a learning environment for Solution-based Problem-Posing in the case of multi-digit subtraction. One of the ways to learn by problem-posing is to make learners pose problems which can be solved by a solution. We call the type of problem posing Solution-based Problem-osing. The Solution-based Problem-Posing helps the learners understand the solution. In the case of multi-digit subtraction, however, it is difficult to provide the solutions directly because the solutions in the multi-digit subtraction are complex for learners who are elementary school students when they learn them. We suggest a method they are required to solve problems to be conscious the solution of the problems and then pose problems based on the solution.
