The necessity of computer science education has been increased in the society which has been changing rapidly by the development of information science. But most elementary school teachers don't realize its necessity and don't recognize the notion of computational thinking which is the fundamental principle of computer science. In this research, we designed and implemented an algorithm learning program based on computational thinking with using Logo, which was for pre-service elementary school teachers to be able to realize the necessity of computer science education and recognize computational thinking. As the findings analyzed between pre- and post-test, the averages of correlational reasoning, combinatorial reasoning and the sum of overall logical thinking increased significantly. Also, participants' awareness of computer science education and computational thinking changed positively.

This case study exemplifies science classroom observation and analysis. Data from two-day classroom observation, pre- and post-instruction interviews with the teacher and instructional materials were used to analyse the features of a science classroom. A teacher's classroom practices were examined in terms of the following six categories: (1)curriculum and science content, (2)teaching and learning methods, (3) teacher' s knowledge about learners, (4)classroom environment, (5)assessment, and (6)teacher's efforts for professional development. The teacher in this case study not only improved his own classroom practices, but also took an active role in teachers' in-service education to share his practical knowledge with others. Implications that valid evaluation(or observation) frameworks of classroom practices have on teacher education and teachers' inservice education are also discussed. These evaluation frameworks should provide teachers with a vision of highly accomplished practices.

In this study, we had tried to present a plan for improving the actual conditions of practical utilization of teaching material for 6th grade science developed by Ministry of Education & Human Resources Development and distributed to all elementary schools in Korea. Also we presented ways of better utilization of the teaching material after investigating the actual conditions of practical utilization. A survey was made to investigate and collect all data in the major metropolitan cities, the Kangwon, Chungcheong, Honam, and Kyeongsang area, respectively. We surveyed 316 6th grader teachers to investigate the actual conditions of distribution and utilization of teaching material as a general research. In addition, we surveyed 46 teachers to investigate the organization and content of teaching material as a particular research. The results are as follows. First, the teaching material was not approximately transmitted and kept to 6th grader teachers. Second, the utilization guide was not made. Third, it was reported that the thematic divisions of teaching material was a strong point, but the less detailed experiment manual was a weak point. Fourth, the consideration of content difficulties and simplicity was necessary to improve the material. Fifth, additional items should be included in the introductory presentation, convenience of reorganization, activity material causing learning interest, guidance of substitution experiment, and more concrete notice of experiment activity. Finally, there were positive responses of more than 4.0 point of Likert scale (1 to 5 point scale) in detail investigations of thematic items, which could have possibility that the teaching material was helpful to elementary school science field.

This study explored the factors influencing major satisfaction and academic satisfaction of science education major students at the College of Education using machine learning models, random forest, gradient boosting model, and SHAP. Analysis results showed that the performance of the gradient boosting model was better than that of the random forest, but the difference was not large. Factors influencing major satisfaction include 'satisfaction with science teachers in high school corresponding to the subject of one's major', 'motivation for teaching job', and 'age'. Through the SHAP value, the influence of variables was identified, and the results were derived for the group as a whole and for individual analysis. The comprehensive and individual results could be complementary with each other. Based on the research results, implications for ways to support pre-service science teachers' major and academic satisfaction were proposed.

This is a qualitative review of research literature on the expertise of science teachers. The study first identified a common point of view which the relevant literature shared about teacher expertise. Research methods employed in previous studies were then categorized into four groups, and the characteristics of each group of research methods were discussed. The groups of research methods included uses of questionnaires and interviews, visual representations, classroom observations and discourse analyses, and narrative inquiry. The study finally suggested what aspects of science teachers' expertise should be considered and what sorts of research methods could be employed for future research in this area.

This study quantitatively investigated the actual situations and perceptions of gifted students and their teachers during small group inquiry activities in Korea. Some 1,670 gifted math students and 1,732 gifted science students as well as 614 of their teachers were selected through random sampling to participate in this study. Data were collected by means of a survey developed by the researchers of this study, based on reviews of literature related to inquiry and small group cooperative learning. The results were as follows: (1) In Korean gifted education, small group inquiry activities were frequently used as teaching and learning strategies, and both the students and teachers perceived its effects to be very positive in terms of cognition and affection. (2) Gifted education teachers emphasized the development of students' procedural inquiry skills as well as logical thinking skills, whereas they were indifferent to the essential elements of small group cooperative learning and therefore the lessons did not surpass the level of traditional group activities. (3) The fact that the actual small group inquiry activities did not reflect the characteristics of well-organized small group activities is due to a lack of knowledge on the teacher's part as to effective teaching strategies concerning cooperative learning. This study implies that gifted education teachers require the opportunity to reflect on and develop their knowledge and understanding of small group inquiry activities through professionally developed programs in order to maximize the effectiveness of small group inquiry activities in gifted education.

The understanding of real-world application of scientific knowledge such as the evolutionary theory has been emphasized in science curriculum. Despite this, many students and biology educators misunderstand the use and practical application of the evolution theory. The purpose of this study is to explore variables related to the understanding of practical application of evolution. Methodologically, we employed large-scale survey that examined three independent variables (major, academic year, and religion) and five dependent variables (understanding of practical application of evolution, knowledge of, interest in, and acceptance of evolution, and religiosity). Two hundred and thirty three biology pre-service teachers and 405 non-biology pre-service teachers participated in the survey. The results demonstrate that the biology teacher education program does not help in increasing the understanding of the practical application of evolution. Rather, the understanding of practical application of evolution was associated with their religion. In addition, the understanding of the practical application of evolution was associated with the acceptance of and interest in evolution. The results of this study inform the development of new biology teacher education programs to improve their understanding of practical application of the evolution theory. We also suggest further areas of research for other scientific concepts that could be used to gauge teachers' understanding of the practical application of scientific knowledge.

The purpose of this study was to investigate the practice of nutrition education and perceptions for implementing nutrition education in elementary schools. In this survey, 833 dietitians, 808 principals and 3,141 teachers across the country were asked about the present status and problems as well as necessity, methods, education time, education subjects and the proper nutrition educator ratio. The results of the survey showed that only 4.2% of dietitians implemented nutrition education during regular school hours or through special activities. Many subjects responded that the reasons for not practicing nutrition education were systematic problems of lack of time due to too much food service work. Especially, many rural area dietitians responded that the reason was lack of time due to joint management and cooking. Many dietitians, principals and teachers responded that the placement of one nutrition teacher in every school is needed to resolve these problems. Other solutions suggested were the introduction of a dietitian internship, and the modernization of foodservice facilities for principals and teachers. Of those surveyed 98.4 percent of principals and 95.5 percent of teachers responded that nutrition education is urgently needed. Many subjects also responded that the first three years of elementary school are the most proper time for nutrition education and it is best that these lessons are reinforced at least once a month through discretional or special activities. Survey participants responded that the proper ratio for nutrition educators is 400-800 persons for dietitians compared to less than 400 persons for principals. In conclusion, it is hoped that this study will be able to provide a foundation of data for implementing a systematic nutrition education program by nutrition teachers in elementary school.

The purposes of the study are to investigate the experiences of major stakeholders (i.e. science teachers, program instructors, local experts, etc.) who participated in implementing Community-Based Socioscientific Issues Programs (SSI-COMM) and to provide educational implications for further implementation. SSI-COMM dealt with three issues (i.e. abandoned pets, fine dust, and recycling) that students often encountered in their local community. Each program, lasting over 16 class periods in a free semester, included in-school and out-of-school activities in order to promote their interest and participation in community. Four teachers, four program instructors, and six local experts joined the interviews to explain their experience of participating in the programs. As a result, school teachers, program instructors, and local experts positively appreciated their experiences of the program implementation and perceived educational potentials of SSI-COMM. All the stakeholders mentioned that they became more interested in local socioscientific issues and strongly perceived the need for the implementation of such programs linked to their own community. The science teachers appreciated the opportunities to identify students' potentials through SSI-COMM and believed that SSI-COMM would contribute to reducing the gap between learning and practice. The program instructors, observed that out-of-school activities contributed to enhancing students' self-confidence and fulfillment in learning. Finally, the local experts obtained a sense of belonging to their community and were very satisfied with their contribution. The SSI-COMM programs are expected to be one of the educational models that will help to encourage the participation of students and stakeholders in facilitating educational activities in relation to the community.

Cooperative program planning and teaching is a strategy for developing and implementing resource based learning. This approach combines the classroom teacher's subject expertise and knowledge of the students with the teacher­librarian's specialized knowledge of the availability and use of learning materials. And the purpose of cooperative program planning is to develop learning experiences or units of study that effectively integrate the student's resource center activities with other learning experiences. There are also some conditions that are conducive to effective planning sessions. First, the teacher-librarian must be prepared to initiate planning with teachers, rather than waiting for teachers to come to them. Second, the teacher-librarian must be prepared to present suggestions in such a way that the teacher can respond. The purpose of this study is (1) to investigate the planning process of cooperative program planning and teaching in the previous studies and (2) to find general problems when the cooperative program planning and teaching apply in actual situation. For these purposes, I chose a school library and a teacher-librarian in Seoul to observe how this cooperative program planning and teaching carry out in the school library. Main findings are summarized as follows: (1) A teacher who teaches alone for one grade is more proper to carry out the cooperative program planning and teaching. Young teachers are usually more active to change their teaching methods. (2) The cooperative program planning and teaching is a program what needs a lot of materials. When there is no right reference book in a school library, it would be good to access DB through PC telecommunication. It is also possile to contact lirarians who work in large public libraries or university libraries. (3) The cooerative program planning and teaching needs cooperative working between a teacher-librarian and a teacher. Thus a teacher-librarian should be in his school in the day time like the other teachers for the program's planning process. ( 4) There has to be a guide to change into resource based learning in teaching method. Thus the Korean Library Association or Korean Library and Information Science Society should offer a seminar or a workshop about cooperative program planning and teaching for the teacher-librarians. (5) It needs a system that a teacher-librarian can know about student's assignments so that he can prepare reference books for them. (6) The school library can be able to offer excellent service like cooperative program planning and teaching to the teachers and students according to a teacher-librarian's enthusiasm.
