The purpose of this study was to investigate the effects of epistemological beliefs(EB) and
self regulated learning(SRL) on problem solving achievement while subjects of 154
pre-service teachers solved well-structured and ill-structured problems. For this purpose,
participants had to fill-out a questionnaire concerning EB and SRL, and then conducting the
well-structured problem and ill-structured problem solving. The results of the study are as
follows: First, on the well-structured problem, the higher group of rigid learning, ability to
learn, and speed of knowledge showed more advanced problem solving achievement.
Especially, they showed excellent performance and high score in solution development and
selection. On the ill-structured problem, the higher group of the nature of knowledge
(certainty of knowledge, source of knowledge) and the nature of knowing(rigid learning,
ability to learn, speed of knowledge) showed more advanced problem solving achievement.
Especially, they showed excellent performance and high score in problem representation,
solution development & selection, solution justification, and monitoring & evaluation. Second,
there were no a significant difference between well-structured problem solving and SRL
level. But, there were a significant difference between ill-structured problem solving and SRL
level. Especially, the higher group of cognitive strategies showed excellent performance and
high score in solution monitoring and evaluation. These results would provide the necessity
of educational program to understand and to improve their EB in teacher education.
