초록
The purpose of this study was to investigate explanations of high school chemistryⅡ textbooks and the diversity of chemistry major teachers' thinking types related to dilute solution properties for finding the sources of students' difficulties. Eight kinds of textbooks were analyzed, and the teachers' thoughts were searched by a questionnaire developed for inquiring teachers' preference of explanation types. We analyzed teachers' responses from individual interviews after the questionnaire to discern their deeper thoughts. From the results, it was found that the explanations of the textbooks were not clear enough to have scientific conceptions. The figures and explanations of the textbooks do not match either. It was also found that chemistry major teachers' thoughts were not solid when they suffered cognitive confliction by different situation with their thoughts.
