- Over the past decade, many students have been losing their
interest in physics. One of the essential reasons why students look
away from physics is the fact that they face difficulty in solving
physics problems. Since mechanics is a fundamental subject in physics,
many researchers have studied how students learn mechanics and solve
problems related to mechanics. However, there is little research focusing
on the students' specific difficulties in the process of problem solving.
This study investigated students specific difficulties (with the degree of
difficulties) and the core sources of these difficulties. 24 university
students who majored in physics education participated in this study.
We have developed a framework, the House Model (HM), for helping
and analyzing students' problem solving. We found that students felt
greater difficulty in planning and executing steps than in visualizing,
knowing and finding steps. As the problems grew in difficulty, this
pattern became more distinct. We found the sources of the students
difficulties and tried to suggest method of helping the students who
experience difficulties in problem solving.
