This study analyzed characteristics which emerged while 38 secondary school teachers observed a video clip about a centroid of triangles instruction. The aim of this study based on the analysis was to deduce implications in terms of the various means which would enhance teachers' knowledge in teaching mathematics and assist in designing mathematics education programs for teachers and professional development initiatives. To achieve this goal, this research firstly reviewed previous studies relevant to the 'Knowledge Quartet' as a framework of analyzing teachers' knowledge in mathematics instructions. Secondly, this study probed the observation results from the teachers in the light of the KQ. Therefore, some issues in the teacher education program for teaching mathematics were thirdly identified in the categories of 'Foundation', 'Transformation', 'Connection', and 'Contingency' based on the analysis. This research inspires the elaboration of what features have with regard to effective teachers' knowledge in teaching mathematics through the analyzing process and additionally the elucidation of essential matters related to mathematics education on the basis of the analyzed results.

This study seeks to examine current status and issues on primary education environment and teachers in Cambodia, a country that has a poor education environment and low educational achievement I analysed the features and limitation of education. Major findings revealed the primary school students' low accessibility on education and poor competencies and qualification of primary school teachers, which have hindered a quality of education in Cambodia. Central implications were produced to improve the quality of education and training system for primary school teachers. First, sustainability should be embedded from the initial design to the performance evaluation of the projects. Second, we should carry forward a customized training project that can meet the needs of primary school teachers in Cambodia. Third, the Education ODA project should be institutionalized into the national mechanism of the credit accreditation system, including the incentives of participating. Fourth, in-service training should ensure the inclusiveness and accessibility for the disadvantaged in remote areas. Fifth, short-term workshops for teachers should be avoided, but intensive programs including mentoring should be expanded. Finally, we should support the establishment of autonomous teacher- learning communities based on school level across the Cambodia, which could establish the social capital of the teaching profession in a long term.

The aim of this study was to deduce implications of the growth of mathematics teachers' specialty for effective instruction about the formulae of exponentiation with rational exponents by analyzing teachers' understanding of the definition of rational exponent. In order to accomplish the aim, this study ascertained the nature of the definition of rational exponent through examining previous literature and established specific research questions with reference to the results of the examination. A questionnaire regarding the nature of the definition was developed in order to solve the questions and was taken to 50 in-service high school teachers. By analysing the data from the written responses by the teachers, this study delineated four characteristics of the teachers' understanding with regard to the definition of rational exponent. Firstly, the teachers did not explicitly use the condition of the bases with rational exponents while proving f'(x)=rxr-1. Secondly, few teachers explained the reason why the bases with rational exponents must be positive. Thirdly, there were some teachers who misunderstood the formulae of exponentiation with rational exponents. Lastly, the majority of teachers thought that $(-8)^{\frac{1}{3}}$ equals to -2. Additionally, several issues were discussed related to teacher education for enhancing teachers' knowledge about the definition, features of effective instruction on the formulae of exponentiation and improvement points to explanation methods about the definition and formulae on the current high school textbooks.

According to the presentation of the new national curriculum, this study aims to analyze teacher's perceptions of the information education for lower grade students in elementary school. Before conducting survey, analyzing overseas and domestic researches were preceded. The questionnaires were collected by an online survey of 166 incumbent elementary school teachers after verification by an expert group. As a result, contrary to the basis of the information education curriculum to be strengthened, teacher's stagnant negative perceptions could be confirmed through various measurement variables. Before the introduction of a new national curriculum in 2024, it is a time when efforts to improve teacher's perceptions of information education for lower graders are particularly necessary.

논술 수업은 글쓰기 수업이나 독서 감상 같은 국어과 과제의 하나로 인식됨으로써 학생들이 흥미를 잃고 자칫 거부감을 느끼게 할 수 있다는 데 현직 교사들이 논술 교육을 어려워하는 요인으로 작용하고 있다. 따라서 본 연구에서는 초등학교 학생들의 글쓰기 교수 학습 방법에 적합한 인지적 도제 이론을 논술 교육에 적용시켜 학습자들이 모델화를 통해 쉽게 이해할 수 있도록 하였고 동시에 동시적 비동시적 의사소통이 가능한 웹상에서 논술 학습을 실시하는 논술 시스템을 설계하고 구현하였다.

The purpose of this study is to research on the professional development of pre-service chemistry teachers in terms of personal practical knowledge(PPK), and draw a discussion for pre-chemistry teacher education. A reflective discussion through a Community of Practice(CoP) activity has been conducted with 5 pre-service chemistry teachers studying in a college of education located in Seoul. The analysis of the results reveals that 'Subject-matter knowledge' is leaning toward massive chemical contents, 'Curriculum knowledge' is below the level of selecting, analyzing, and applying curriculum materials. 'Instruction knowledge', especially the knowledge of chemistry experiment and research, is not enough to lead secondary students' scientific experiment. 'Milieu of school knowledge' is stunted in growth for the reason of communication-deficiency between a college of education and a community, and among education- related groups. 'Self-knowledge' has been diminished not only because there is a bad influence from college classmates not wanting to be a teacher, but also a lack of communication in the chemistry-education department which can make pre-teachers' belief strong. In conclusion, it is especially needed for the chemistry-education department to strengthen pre-teachers' 'Self-knowledge' in order to develop PPK. This study suggests operating 'a professional community' that has a periodic meeting with pre-service teachers, teachers, professors, community people, education practitioners, and researchers. In addition, it would be effective for increasing pre-teachers' PPK to reconsider depth and direction of 'Subject-matter knowledge', to give an opportunity to examine curriculum materials critically and reorganize them, to improve the course of chemistry experimental subject to the way of improving pre-teachers' leadership in chemistry inquiry experiment, and to raise the quality of educational service activities.

This study aims to make a research on the secondary school education of geography and the system of teacher training in Belgium, focused on the case of Francophone Community. What has been made clear by this research can be summed up as follows. The first two years of the secondary school offer two hours of 'environment education', per week, which can be categorized into the learning of living geography, in that at this stage students learn how to observe the geographic phenomena in their daily life and pigeonhole them. The two years of the second stage of the secondary school offer one hour of 'world geography' which actually is focused on the district of Europe and Russia. The two years of the third stage of the secondary school offer an advanced course of geography which aims to teach systematically the physical geography and the human geography. A remarkable change in geographic education in Belgium is that in the wake of the Revision Act of the secondary school education, textbooks were replaced by other teaching manuals adapted to the regional condition by the teachers. This may result in a wide gap of achievements in geography according to the conditions of educational establishments. Another notable change is that the stress of geographic education tends to be placed on the ability of acquiring practical geographic knowledge rather than the geographic information itself. And it is also another marked tendency that most learning activities in geography class are conducted on the basis of student-centered and the method of investigation. Teachers of the lower secondary schools in Belgium are trained in the School of Education as multi-major teachers, such as a teacher for biology-chemistry-geography or a teacher for history-sociology-geography. Teachers of the higher secondary school education are trained in the Department of Teacher Education in universities as solo-major teachers in that they are required to know more deeply to teach an advanced course of geography in the higher secondary schools. To improve the teacher education many folds of policies are adopted. One is that many in-service teachers are officially put into services of guiding and teaching teacher training. Another is that faculty members in charge of teacher training course are trying to level up the qualifications of teachers by rigorous disciplining.

The purpose of this study was to investigate inservice elementary teachers' view and the change of preservice elementary teachers' view on the nature of science by the science education course. The subjects were 386 junior preservice teachers in a National University of Education and 257 inservice teachers working in a metropolitan city. An instrument consisting of fifty eight items were developed on the bases of previous studies. Before entering the course, preservice teachers view was compared by gender with T-test and no significant differences were found except the category 'role of a scientist'. Preservice teachers view was also compared by major with ANOVA and significant differences were found on the categories 'scientific method' and 'scientific law'. After the course, on comparing their view by gender, significant differences were found on the categories 'scientific theory', 'scientific knowledge', and 'scientific law'. The result of ANOVA by major, significant differences were found except the category 'role of a scientist'. Inservice teachers view was compared by gender and major and the differences were no significant, the significant differences, however, were founded in comparing by career and ability.
