The purpose of this study is to suggest a new direction in using LOGO as a gifted education program and to seek an effective approach for LOGO teaching and learning, by analyzing the strategic thinking of mathematically gifted elementary students. This research is exploratory and inquisitive qualitative inquiry, involving observations and analyses of the LOGO Project learning process. Four elementary students were selected and over 12 periods utilizing LOGO programming, data were collected, including screen captures from real learning situations, audio recordings, observation data from lessons involving experiments, and interviews with students. The findings from this research are as follows: First, in LOGO Project Learning, the mathematically gifted elementary students were found to utilize such strategic ways of thinking as inferential thinking in use of prior knowledge and thinking procedures, generalization in use of variables, integrated thinking in use of the integration of various commands, critical thinking involving evaluation of prior commands for problem-solving, progressive thinking involving understanding, and applying the current situation with new viewpoints, and flexible thinking involving the devising of various problem solving skills. Second, the students' debugging in LOGO programming included comparing and constrasting grammatical information of commands, graphic and procedures according to programming types and students' abilities, analytical thinking by breaking down procedures, geometry-analysis reasoning involving analyzing diagrams with errors, visualizing diagrams drawn following procedures, and the empirical reasoning on the relationships between the whole and specifics. In conclusion, the LOGO Project Learning was found to be a program for gifted students set apart from other programs, and an effective way to promote gifted students' higher-level thinking abilities.
This study analyzed achievement standards in the 2015 Science Education Standards as well as activities and assessment items in the Integrated Science, Chemistry I, and Chemistry II textbooks using science core competencies and subcomponents. All five scientific core competencies, in order of scientific thinking capacity, scientific inquiry capacity, scientific communication capacity, scientific problem solving capacity, and scientific participation and lifelong learning capacity, were included in the achievement standards of Integrated Science. Scientific thinking capacity, scientific inquiry capacity, and scientific communication capacity were included in the achievement standards of Chemistry I. The achievement standards of Chemistry II only included scientific thinking capacity. All five scientific core competencies were involved in activities of Integrated Science, Chemistry I, and Chemistry II textbooks and the highest propotion was scientific thinking capacity and scientific inquiry capacity. All five scientific core competencies were involved in assessment items of Integrated Science, Chemistry I, and Chemistry II textbooks and the highest proportion was scientific thinking capacity.
The purpose of this study was to develop inquiry modules for learning straight propagation of light, to verify their efficiency, and to acquire implications. this study proposes teaching modules for improvements of light experiments, which were developed in this work. Inquiry modules were applied to 75 school teachers(8 elementary school teachers, 67 middle school and high school teachers) for examining that the modules make teachers have the scientific concepts. Then, conception changes were analyzed except 5 teachers who responded poorly. The pre-test result shows that most teachers have alternative conceptions, which is that they thought the bright shape on apparatus's bottom panel itself shown in the textbook as evidence for the path of light's straight propagation. The post-test result shows this alternative conception was changed into scientific conception. Unlikely pretest, most teachers' conception was changed into the scientific conception that the light come from a light source. Teachers are able to express that the light beam comes from a miniature electric bulb. Further more, most teachers can draw light's path correctly; from the miniature electric bulb, through vertical panel having a hole, to the apparatus bottom.

The purpose of this study was to examine the science writing and perception of students who experienced the argument-based claim and evidence writing approach. One hundred and eight grade 11 students were assigned to an experimental group, while 99 grade 12 students were assigned to a comparative group in their earth science classes. Students' science writings on two science topics were scored using an analytic rubric developed in this study. The comparison of experimental and comparative groups in science writing was carried out using an independent two samples t-test. Students' perception on the instruction was examined using an open-ended survey. Science writing by the experimental group scored significantly higher than that by the comparative group, except for the big idea of 'green energy'. For six concepts in 'green energy' and four concepts in 'plate tectonics, there were more students in the experimental group than the comparative group who indicated them in their science writing. Students' perception on the instruction was positive in that they mentioned planning and conducting inquiry, citing of claims and evidence, and developing inquiry questions were helpful in science learning. The results of this study imply that the argument-based claim and evidence writing approach should be implemented in science classrooms for students to develop a conceptual framework for science.

Students are exposed to many visual representations in various visual cultures. Infographics combining visual representations and writing can effectively convey information. Also it can be efficient ways for teachers to focus on important contents. Students can use infographics as a method directly to organize information. Therefore, the infographics that students use both writings and images directly and visually will be more effective on elementary school science classes than the workbook. Classes are guided with the same scientific inquiry and experiment written on the science textbook. The experimental group students organized scientific inquiry by infographics, while the comparison group students still used the workbook. First, the types of infographics are determined by what students want to explain. Based on learning objectives, students used the right type of infographics to effectively convey their focus on information. Second, the infographics organizing activities used in the classes had a significant effect on students' academic achievement. Also, the infographics organizing classes are positively associated to science-related attitudes, including such+ as 'Leisure Interest in Science', 'Adoption of Scientific Attitudes', and 'Attitude to Scientific Inquiry'. Third, visual tendency and classroom treatments had no interactions, but the experimental group had a positive impact regardless of student's characteristics. Fourth, experimental group showed positive attitudes toward to students' perception of infographics. Since some of students had difficulties organizing information in infographics, further research is required to enable students to reduce their burden in application of infographics.
The purpose of this study was to find out the validation of instructional strategies using the Advanced Laboratory Equipment (ALE class) by investigating science high school students’ perception on ALE in chemistry classrooms and to consider the need for development of teaching materials on ALE class. 7 sessions of ALE including experiments with innovative equipment were developed and applied to 21 students in D Science High School. At the end of the sessions, questionnaire was given to the students. We also collected qualitative data by interviewing 9 students who participated in the questionnaire. We analyzed the data collected by In-depth interviews and students’ experimental reports. The result showed that ALE class was effective to enhance students’ understanding of learning concepts because the experimental time was shortened in real time data processing. Some students showed creative performance on solving scientific problems by using everyday materials in experimental process and developed perceptions of practical inquiry. Through this process, students’ positive attitudes and interests in science and heuristic inquiry skills were also enhanced. Developing ALE lesson materials will be helpful for students to understand science and technology and the domain of science in broader contexts.

The purpose of this study was to understand the influence of the inclusive leader on group interactions in scientific inquiry experiments emphasizing group interactions. For this purpose, the students' verbal interaction patterns in groups with inclusive leaders were compared with those of groups with normal leaders and the inclusive leaders' influence on the progress of group interactions was analyzed extensively. This study focused on interactions of four small groups of seventh graders, with two having inclusive leaders and two having normal leaders. Students were involved in seven science classes for three weeks and students' interactions in each class were observed and recorded using video/audio. The data recorded was transcribed. Analysis of verbal interaction patterns showed that the small group with the inclusive leader had a more positive atmosphere and highly structured interactions. Results of the study showed that interactions of small groups with inclusive leaders were sustained for longer times, since the inclusive leaders initiated and expanded interactions. The inclusive leaders behaved with consideration of the feelings of other members in sharing their roles or facing critical situations. In addition, although they sometimes gave pressured other members to get them to participate, the pressure did not discourage their interaction as opposed to the emotional pressure that normal leaders would exert. The inclusive leaders were pleased with small-group interactions and activities. They considered the feelings of the other members and respected others' opinions. Such characteristics of inclusive leaders preserved a positive atmosphere and produced more high-level interactions. Thus, the groups that inclusive leaders had influenced had a pleasant and significant learning experience. Educational implications of characteristics of the inclusive leader and the organization of groupings were drawn.
In this study, science teachers' NOS lessons were observed and the characteristics of the lessons were analyzed. Three science teachers who taught NOS in the 'Science Inquiry Experiment' developed under the 2015 revised curriculum participated in the study. Their NOS lessons were observed and interviews were conducted before and after lessons. The collected data were analyzed using analytical induction and constant comparative method. The analyses of the result revealed the teachers' naive views on NOS were also revealed during the lessons. There were some cases where they showed naive views during the lessons even if they showed informed views in the interviews. Although the domains of NOS taught by them were diverse, all of them taught 'tentativeness' and considered this an important goal. They tended to teach NOS with content related with their major, and teaching NOS was found to be deeply related to their major. In the activity where students learn NOS by inferring the unknown object, teachers disclosed the unknown object, which is unlike the rule of the activity. They thought that could help students' learning. At last, although they emphasized teaching NOS, they either did not assess NOS or assessed NOS in a limited way. Based on the results, some directions for teacher education and follow-up study are suggested.
Considering the importance of spatial thinking in the process of learning astronomy, it is necessary to educate pre-service teachers on teaching methods that consider spatial thinking from the teacher training program stage. Accordingly, after providing education on spatial thinking to pre-service science teachers, problems and improvement plans perceived by them were explored for the images and inquiry activities of astronomy textbook units. In this study, spatial thinking in the astronomical domain was defined as the amalgam of the concepts of space, representation tools, and reasoning processes. The juniors attending the University of Education in the metropolitan area were educated on spatial thinking for two weeks in October 2021. They were then asked to voluntarily select one of the astronomy units to analyze problems in the textbooks and present modification plans to address those problems. Finally, 33 cases presented by 22 pre-service science teachers were analyzed, and the results of the study were as follows. Pre-service teachers recognized the problems in textbooks in terms of the concepts of space and reasoning processes, and proposed improvement plans to supplement them. However, in some cases, even if pre-service teachers properly recognized a problem, the improvement plan was not appropriate, or they were not able to analyze the images or inquiry activities in terms of spatial thinking. This study is significant in that it shows that pre-service teachers have the potential to properly reorganize and revise textbooks by participating in teacher training programs on spatial thinking. Furthermore, based on the results of this study, the direction of the teacher training program concerning spatial thinking was discussed.
The purpose of this study is to examine the anxiety arising from the budgetary and mental problems of graduate school students. Three graduate students majoring in Earth science examined conflict situations by using a narrative inquiry technique. First, participants become psychologically unstable due to a lack of knowledge in the field of Earth science, lack of mentors, lack of information related to academic schedules, late start compared to others, financial difficulties, and discrimination in the scholarship system. Second, participants felt hope from the perception that their lives are valuable, that they can change students for the better, and that they are developing themselves. Third, with their hope, the study participants bore the previously mentioned inferior situation mentioned above. They are, however, torn between becoming secondary school teachers and attempting to reroute their career path due to certain circumstances. Based on the results of the examination, the following conclusions were drawn. First, there should be improvements from graduate school management based on collecting and scrutinizing the demands of students in the to fulfill their needs. Second, providing psychological counseling for students who have problems overcoming their anxieties. This study expects graduate schools to not only emphasize training of incumbent teachers, but also suggest ways that can satisfy students to make better learning environment for all its members.
