Documentation is a typical method that helps students to understand a program for implementation and execute error correction and maintenance cost-effectively. Guidelines for components that organize documentation should be provided to enable to express computational thinking and such components also should be linked to coding process. In this paper, we focused on the documentation format to guide elementary school students, who were beginners in computational thinking, to express computational thinking. The improvement in the expression of computational thinking was analyzed based on the documentation format applied to the class, and practical tips on the importance of components organizing the documentation format were proposed.

In this study, we analyzed the characteristics of Pedagogical Content knowledge(PCK)'s components through actual course of teachers of science gifted students in the middle school. For this study, four middle school science teachers of gifted students belonging to the gifted education professional organizations in a metropolis were selected, each of them was physics, chemistry, biology, and earth science teacher. Two of them were full-time teachers to teach only gifted students and two were part-time teachers who had taught general students in ordinary time and specially had taught the gifted students once a week. Qualitative data were collected through classroom observations, interviews, and documents. As a result, some unique characteristics of PCK's components were identified. The teachers' orientations to teaching science were closely correlated with PCK's components. The teachers' knowledges of science curriculum were different individually. But the decisions about type of teaching(acceleration or enrichment) were connected with the objectives of gifted education and lesson objectives. Also, the teachers' knowledges of science curriculum were influenced by the knowledge of students' understanding. Teachers used different instructional strategies according to the knowledge of science curriculum and the knowledge of students' understanding. We found that PCK's components were so closely connected and could show the direction of relationships among those PCK's components. We suggested teachers' PCK model which was named "Tetrahedron Model of PCK", to explain the characteristics and relationships of PCK's components.

This research defined professionality of science teacher from the perspective of PCK. An teaching strategy in the in-service teacher training for the gifted education was proposed based on the definition and implemented at an in-service teacher training program for the gifted education in order to explore about the teaching strategy and suggest practical implications that could improve the program. The in-service teacher training teaching strategy proposed in this research consists of three components: 'crafting activity materials', 'conducting inquiry-based experiment', 'developing rubric for identification of giftedness'. The survey carried out for the participants of the teacher training program showed that teachers perceived the importance of the need for the rubric for gifted identification, developing activity materials for the gifted education in science, and developing the rubric of gifted identification as properties for in-service teacher training programs fur the gifted education. However, the insufficiency of time and opportunities for being fully engaged in such a program made teachers feel lack of self-confidence in developing activity materials for the gifted education in science and rubric for gifted identification. Therefore, teacher training programs reflecting real features of the gifted education should be constantly developed and provided to enhance the effectiveness of in-service teacher training programs.

This research attempts to establish a strategy through which to secure the introduction of the KEM 2.0 system. Another aim of this research is to eventually establish a service system which can be used to automatically generate and provide the metadata information contained in the Cylearn system. in order to facilitate Korean vocational high school students access to teaching-learning materials. The main research tasks associated with this research were: 1) To establish the components of the file server system while taking into consideration the environment in which each educational organization operates; 2) To utilize the KEM 2.0 in order to optimize the configuration of the Cylearn system and the related software. To do so, the KEM 2.0. should be applied in close coordination with Edunet: The results of this research can be summarized as follows: First, a strategy to introduce the KEM 2.0 was established. To achieve this, the researcher analyzed the characteristics of the sequencing and presentation methods and suggested teaching-learning materials based on the KEM 2.0.s sequencing system. Second, the file server was constructed using the KEM 2.0. The established file server took into account the environmental conditions in which the Edunet system operates so as to facilitate the creation of a network system with Edunet. Third, the Cylearn service system was linked to Edunet. The researcher developed a module using the KEM 2.0. that could be used to transmit the metadata related to teaching-learning materials to Edunet. To achieve this, an input device and a databank which could be used to transfer the generated metadata to Edunet were developed. The input device and databank developed using the KEM 2.0. were used to transfer the metadata to Edunet by linking the Cylearn system to the Edunet system.

The purpose of this study was to investigate the interaction of science PCK between two elementary school teachers by the teacher collaboration within the school. We chose the case that two teachers collaborated spontaneously in the 5th-grade science classes. Even though they had similar teaching experiences, one of them had the science PCK while the other did not. As a result of this study, two teachers began to collaborate to avoid comparisons of science classes between them. They shared the same teaching plan but practiced science teaching individually. During they taught science, they usually collaborated on the instructional sequences, student's activities, and the content of assessments. They had an in-depth collaboration when the teacher who lacked the science PCK asked help to teach problem-centered learning by science inquiry. During the collaboration, their science PCK components, especially the knowledge of instructional strategies for teaching science, shared and it affected the teacher's science practices who lacked the science PCK. However, they did not usually share the knowledge of teaching for their everyday science classes because two teachers had the perception of noninterference about their science classes. This case has the limitation that it is hard to generalize the results but teacher collaboration shows the possibility to develop the elementary school teachers' science professionalism by having peers in the school who can help them in science classes.

Under the assumptions that teachers' beliefs toward mathematics education play a role of a filter between teachers' knowledge and teaching practices, this study surveyed and analyzed elementary teachers' beliefs toward mathematics education: helping students to understand mathematics concepts, addressing students' mathematical misconceptions, engaging students in mathematics classroom, and improving students' mathematical thinking. From the analysis of survey results of the study, I found that there were dominant components in elementary teachers' beliefs system regarding teaching mathematics. In addition, there are some constructs affected by teachers' characteristics such as gender and educational backgrounds. In this study, I presented a representative model of elementary teachers' beliefs system toward mathematics education.

The study was designed to describe the pre service teachers' development of their TPCK throughout the teacher preparation program that integrated technology throughout the program and how they succeeded in teaching with technology in the actual classroom during student teaching. Multiple data sources were used to obtain information toward answering the research questions. Overall, the emphasis of the teacher preparation program in this study in helping preservice teachers to acquire TPCK transformed the preservice teachers' understanding described by the four components of TPCK. However, the diversity of beliefs, teaching, and technology background affected their understanding and development of TPCK throughout the program.

Recent developments and integration of IT are expanding the possibility of various instructional learning methods in education environments. Contemporary learning theory such as open education, self-directed learning, student's centered learning describes the students as an active and engaged information user and underscores the importance of information literacy. Therefore, school library today focus on the process of learning-teaching process rather than dissemination information, and emphasized the focus of the school electronic library as information center. The purpose of this study is examined physical components of School Electronic Library, design a model of information system and suggests a strategy for implementing teaching-learning process support services based on school electronic library and information system.

In this study, we analyzed the PCK components in the materials units of the third and fourth grades of the Korean government-authorized teacher's guides for elementary school, developed in the 2015 revised national curriculum. The results showed that the PCK components were presented in a relatively balanced manner compared to the teacher's guides for middle school. Knowledge of the subject matter accounted for the highest proportion, and knowledge of instructional strategies in science accounted for a higher proportion than knowledge of the science curriculum. The knowledge of assessment in science showed the greatest deviation among publishers, and knowledge of students tended to show the lowest. By subcomponents, experiments and inquiries had a higher proportion than concepts and theories. The ratio of horizontal articulation was lower than that of vertical articulation or lesson objectives, and lesson objectives were presented in various ways, such as in core competencies and achievement standards for science. As questioning was emphasized, teaching strategies and questioning appeared at a similar rate. Motivation and interest, misconceptions were linked to teaching strategies and questioning. In some cases, assessment items and assessment criteria were presented at each level, and various PCK components were linked to these two components. Components with relatively large differences among publishers were supplementary or in-depth concepts, inquiry in textbooks, instruction sequence and method, subject-specific strategies, and assessment items. From the results, the implications for the development of teacher's guides were discussed.

In this paper, we analyze what the components of mathematics teacher` knowledge are, and find that mathematics teacher need knowledge of three areas: subject matter knowledge, pedagogical knowledge, and pedagogical content knowledge. Studies of practicing teachers suggest that When teachers lack understanding in their respective disciplines, it inhibits them from providing students the best learning opportunities, but that a teacher possessing pedagogical content knowledge provides learners with multiple approaches into learning. Some teachers having sound knowledge of mathematics and students were able to respond appropriately to students' questions, design appropriate learning activities involving a variety of mathematical representations, and orchestrate mathematical discourse in the classroom. Thus, it appears that mathematics teachers' knowledge positively affect teaching and student learning..
