  • This study aims to analyze middle school students' systemic thinking to express organic relations between different organ systems about the movement of food and air and teachers' reflective thinking about science teaching through their reflective journals after the lesson of digestion, circulation, respiration and excretion. Firstly, when investigating the moving route of hamburger eaten inside the body, students expressed the names, locations and forms of organs in the digestive system more than those in the circulatory system or the excretory system. When investigating the moving route of a painkiller taken inside the body, students seemed to have more difficulty in expressing the related organ systems than when investigating the moving route of other things, and they mostly drew pictures of organs in the digestive system as done for the moving route of hamburger. However, when investigating the moving route of water drunk inside the body, students mostly described organs in the digestive system but drew more pictures of organs in the excretory system, than when investigating the moving route of other things. When investigating the moving route of air inhaled inside the body, students mostly drew pictures of organs in the respiratory system, but the rate of their drawing pictures of circulatory organs was low. Secondly, this study analyzed one of the teachers' reflective journals, named Mr. Park. According to his journal, students showed different levels of understanding of organ names, depending on their degrees of familiarity with each organ, and in regard to the locations of organs, science teachers mostly aim to achieve learning objectives so much that they often forget to instruct the locations of organs in fact. As for the forms of organs, science teachers mostly spend so much time explaining the functions of organs that they often forget to describe the exact form of each organ.

  • This study analyzed the thinking types of pre-service chemical cell chemistry teachers according to grade and tried to find out how the education for pre-service teachers had influenced their thinking types. This study found that the pre-service education had failed to form scientific conceptions. Some pre-service teachers thought that college education couldn't help them understand the knowledge about chemical cell. In addition, they are lacking in scientific conception. Even some of them who thought college education was helpful had wrong conceptions. Most of the pre-service teachers' thoughts could not exceed the level of the high school chemistry textbooks. But, Juniors had more scientific conception than other grades through the group discussions about chemistry textbooks' contents in the course of "Theory of Science Teaching Materials". So, Pre-service education should include the pedagogical knowledge with content knowledge treated in secondary school science textbooks for educational effects.

  • This study presents a step-by-step analysis of the experiences and discussions of five elementary school teachers while developing the Augmented Reality (AR) science educational materials, using the Unity Physics Engine. In the preparation phase to develop the AR materials, the teachers explored the features of the AR technology and decided to create AR materials for experiments related to magnetic fields in the magnetism unit, based on discussions about the unit selection. In addition, they complained about difficulties arising out of the lack of background knowledge about the C# programming language in the preparation phase. During the material development stage, there were difficulties in operating the unfamiliar interface and other functions of the software. However, this was overcome through knowledge sharing and collaborative communication among the teachers. The final materials developed were marker-type AR materials to perform experimental activities by changing the position of the magnet and the compass markers. Based on the developed materials, the teachers discussed their smooth utilization during the classroom activities.

  • 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 goal of this study is to examine the Integrated Science and Science Laboratory Experiments of the 2015 revised curriculum applied since 2018, and to explore ways to improve these two subjects in preparation for the 2022 revised curriculum. A survey was conducted by randomly sampling high schools across the country, with a total of 192 science teachers participating. In addition, 12 high school science teachers were selected as focus group, and in-depth interviews were conducted to investigate ways to restructure common science courses for the next curriculum. Main research results include that most schools were operated in 6~8 units for Integrated Science, and the teachers in charge of Integrated Science per class averaged 2~3 over the three years. For Science Laboratory Experiments, it has operated for a total of two semesters, one unit per semester, and it was found that several science teachers are in charge of Science Laboratory Experiments to fill the insufficient number of hours regardless of major. In the in-depth interview, science teachers argued that Integrated Science should be reduced and restructured by strengthening key competencies in preparation for the high school credit system. Based on the research results, ways to reorganize Integrated Science focused on big ideas, ways to construct common science courses based on fundamental science concepts that can guide elective courses, the necessity of career guidance through common science courses, and the necessity of strengthening teacher professionalism for teaching interdisciplinary and multidisciplinary subjects were suggested.
