Abstract
The purpose of this study is to examine the structure of factors that affect attitude toward thinking activities during experiments. Extracted from previous studies, the study hypothesized that attitude is influenced by three factors: (1) understanding the purpose, (2) thinking skills, and (3) perseverance. The 11-item questionnaire, which measured these three factors in addition to attitudes, was administered to 134 junior high school students. The study revealed that the questionnaire had research validity. In addition, the analysis in the Structural Equation Modeling indicated that the effects of understanding the experimental purposes and thinking skills are influential factors on the attitude towards thinking activities. On the other hand, the direct effect of perseverance is relatively small.
