Using Qualitative Data to Test Computer Models of Children’s Word Problem Solving

Abstract

Over the past few years a considerable number of studies have been undertaken that try to assess and to get a better understanding of young children’s problem solving with respect to simple addition and subtraction word problems. This research has resulted in the construction of models of children’s problem-solving processes, and some of these models have been translated in computer programs. These programs simulate the knowledge and actions that are required to understand and solve addition and subtraction word problems. On the basis of such a computer model predictions can be made concerning the level of difficulty of different types of word problems, the strategies applied to solve them and the errors that one can expect as a consequence of specific shortcomings in children’s knowledge and actions.
