  • The revised curriculum in 2007 adds an open inquiry approach to increase students' creativity and interest in science. Because it is the first time for elementary students to perform the open inquiry due to the national curriculum, it is essential that teachers give students' successful experiences in order to build a positive impression about inquiry activity. The purpose of this research is to develop and apply the open inquiry program. The research findings are as follows: First, we analyzed the students' traits of open inquiry ability during the program. The third and fourth grade students showed weakness in operating and inquiring abilities. They also feared failure and were unable to concentrate in classes which were based on explanation or discussion. When students had unexpected results, however, their inquiring abilities and creativeness increased considerably. Additionally there were some students who were stressed during the science-inquiry activity, due to no interest in science and an inability to think scientifically. Second, we developed an open inquiry program for elementary students. The program was modified, reflected upon the students' traits during open inquiry in class. Through repeated feedback like this, we completed the program. Third, for those who studied in the lessons there was a meaningful change in students' science inquiry abilities and abilities to perform 'formulating a hypothesis' and 'the control of variables'. These students' level of self-inquiry performance improved steadily. Moreover, they obtained a strong attachment to their inquiry and understood the method of quantitative experiments.

  • Scientific literacy has long been as one of the key goals of science education, and using scientific inquiry in school science has became an important objective to be achieved. The processes of scientific inquiry consist of proposing/developing inquiry question, designing and conducting investigation, collecting, analyzing and interpreting data, and communicating the results. However, most students experience mainly collecting and transforming data in inquiry processes in science class and they are barely exposed to the opportunities of proposing/developing inquiry questions. Middle school earth science preservice teachers participated in this study (N=36) and their abilities of developing inquiry questions were surveyed. Participants' abilities of developing inquiry questions were investigated whether they were enhanced with activities using the Inquiry Questions Development Guide (IQDG). Also, this study was interested in whether there was any relationship between abilities of developing inquiry questions and designing inquiry investigation. The results of this study were as follows; first, the level and preciseness of inquiry questions and its preciseness developed by participating teachers were enhanced after experiencing IQDG. In addition, teachers' dominating inquiry question-types were two: one is a 'relationship-inquiry question' in which students could discover the relationship between results found in the given experimental situations and the other one is a 'why-how inquiry problem' in which students could explore a cause or a process that results in the outcomes. Finally, the higher level of and preciseness the of inquiry questions were identified as an important factor the determined teachers' abilities of designing more logical investigation. A process of proposing/developing inquiry question was identified as one of the most important processes contributing to a success of scientific inquiry investigation.
