Abstract
The purpose of this study was grouping students' perception types on the unexpected results in experiments, and looking into how the problem-solving experiment affected the change of these perception types. In order to answer this, interview data were analyzed in terms of perception types, and through analysis of questionnaires carried out at the beginning and the end of the semester, the change of perception types was researched. As a result, perception types of students divided into 'the difference between theory and practice,' 'inexperience of experiment skill,' and 'No reading between lines in manual.' After performing the problem-solving experiment for one semester, the perception of 'the difference between theory and practice' declined, and the desire for 'reading between lines' increased, so the problem-solving experiment influenced on the change of perception positively.
