The effects of revised problem based instruction on raising achievement of mathematics underachievers

문제중심보완수업이 수학과 문제해결력 및 학업성취에 미치는 영향

This study is based on the observation of preceded research that problem based instruction is effective in acquiring advanced mathematical knowledge but is not effective for raising mathematical achievement. The treatment of this experimental research is named 'revised problem based instruction' because it adds an expository session to the original problem based instruction. Then the purpose of this study is to make sure that revised problem based instruction is effective in raising mathematical achievement of underachievers.
