摘要：This study aim to improve student achievement and attitudes toward mathematics through heu ristic problem solving to solve math story problems. This was a collaborative classroom action research (CAR). The research collaborator was the fourth grade math teacher as the action doer. The data were collected through student achievement test, questionnaire students attitudes toward mathe_x005f?matics, and observation. The instrument included student achievement test, questionnaire attitudes toward mathematics, and observation sheets. The data were analyzed by quantitative descriptive ana?lysis. The results of the study showed that students' achievement and attitudes toward mathematics improved after the learning actions using the heuristic problem solving in solving mathematical word problems. Achievement test before the action was 59.5%, and increased 72.9% in cycle I, and increased again to 91.8% in cycle II. Results of students' attitudes toward mathematics questionnaire also increased, from 48.7 on pre-action, increased to 81.1 with the positive criteria in cycle I and increased again to 86.5 with the positive criteria in cycle II.
