  • In this study, we investigated how 'Scientific Inquiry Experiment,' a newly introduced subject under the 2015 revised curriculum, was implemented to identify the difficulties that science teachers face in the process of teaching the subject and to explore how to support them through online survey and interview methods. A questionnaire of the survey, which consisted of environmental factors of class, preparation and execution of class, teacher self-evaluation of class, and direction for the subject, was developed, and the online survey was requested with a response from one teacher per school from 1674 high schools nationwide. We analyzed the results from 814 teachers who answered all required questions, and we also conducted interviews and online advisory discussions to ensure the validity of our analysis. In the results of the study, teachers complained of lack of time for preparation and execution of the subject, and they demanded laboratory assistants and quality teaching materials. In addition, in order to achieve the goal of the subject, they agreed the necessity of using the 'block scheduling' though they also agreed the difficulties of its implementation. Meanwhile, the alteration of guidelines for evaluation, which was changed from 9-grade system to 3-grade system, was positively recognized by teachers. As a result of this change, the percentage of performance assessment increased in 2019 compared to 2018, but there were no significant changes in the number of 'hands-on activity.' Finally, we proposed ways to support 'scientific inquiry experiment'.

  • This study aims to investigate the effect of inquiry-based biology program of pre-service science teachers' perceptions on the nature of science and their affective domain of science. For the study, sixty-seven pre-service science teachers were sampled from students who enrolled in the 'Biology Laboratory', Spring semester, 2011. The experimental group taught by inquiry-based experiment and control group by observation-based experiment were composed. At the beginning and end of semester, pre- and post-tests on the nature of science and affective domain of science were administered. The average scores of experimental group were higher than those of control group in the post-test of the nature of science, but there were no significant differences between both groups (p>.05). For the post-test results of both groups' affective domain of science, the experimental group showed significantly higher scores than the control group in self-efficacy in science, importance of science, and importance of science for careers (p<.01). The inquiry-based biology program did not influence pre-service science teachers' perception on the nature of science, while it was effective for positive changes on pre-service science teachers' affective domain of science.

  • The purpose of this study was to explore changes of elementary science class in student oriented group inquiry activities using a Science Writing Heuristic (SWH) template that enhance scaffolding of inquiry. The changes focused on students' written reports and perceptions of their learning environment as well as discourse patterns. One fourth-grade class of 29 students participated in this study, and a developed work sheet of science writing was utilized to scaffold student's inquiry activities. Four units in the first-semester text book for fourth grade of the-, 2007 Educational Curriculum Revision were chosen for scaffolding inquiry, and sixteen lessons of instruction were all videotaped. For investigating students' written reports, a framework based on the aspects of science inquiry by Millar (2010) was used to evaluate the coherence between student inquiry activities and their claims. Secondly, a regular fourth-grade class was selected as the control group and was compared with the experiment group using the pre- and post-test of the survey on the perception of science class and science. Lastly, students' discourse patterns of the beginning science lesson were compared with those of the closing lesson. We found that the coherence in the last class increased significantly in students' written reports compared to the first one. Findings also indicated that students' perceptions on their learning environment moved toward student-centered. Based on our discourse patterns analysis, the last class was more student-centered from being teacher-centered than the first one.
