Does a self-report questionnaire predict strategy use in mathematical problem solving among elementary school children? Importance of question format depending on the grade

Abstract

Predicting the actual performance of strategy use with self-report questionnaires is difficult, especially among elementary school children. Nevertheless, due to the simplicity of self-report questionnaires, it is desirable to identify one that can predict children’s performance of actual strategy use. This study investigated whether a self-report questionnaire on the frequency of using a diagram strategy in mathematical problem-solving can predict children’s actual diagram use by manipulating the question type (i.e., free description, multiple-choice, and Likert scale). We also examine the question types that can better predict the actual strategy use in elementary school children. Fourth- to sixth-grade children were asked to complete both a questionnaire, which asked about their daily use of a diagram strategy through three question types and a test consisting of math word problems. We found that when children were asked to self-report their strategy using a Likert scale, they were predicted to use diagrams during the test regardless of grades. Furthermore, the older the children became, the more effective it was to ask them to self-report in a free description type. These results suggest that appropriate question types can make it possible to measure actual strategy-use behaviors through self-report measures, even for elementary school children.
