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