이 연구는 전하 이동을 강조한 튜토리얼을 통하여 초등 교사의 전기 개념 변화를 분석하고, 초등 교사 교육을 위한 시사점을 얻는데 있다. 튜토리얼은 사전검사, 워크시트, 사후검사로 구성되었고, 내용은 두 개의 대범주인 정전기 영역과 전류 영역으로 이루어졌다. 현직 초등 교사 68명에게 튜토리얼을 적용하고 선택형 질문지, 사전 검사, 사후 검사, 워크 시트, 튜토리얼 과정 녹화 전사본 및 면담을 통하여 초등 교사의 전기 개념 변화를 분석하였다. 연구 결과, 교사들은 도체와 부도체의 전기적 특성에 대해 이해하게 되었는데, 마찰과 유도, 접촉에서 전하들의 움직임을 고려하고 설명할 수 있게 되었다. 그러므로 대전과 전류를 혼동하는 어려움이 해소되었다. 열린 회로에서는 전압을 전하가 받는 힘을 고려하여 이해할 수 있게 되었고, 축전기를 통해 일시적 전하의 이동을 설명할 수 있었다. 이것은 전압이 전류의 결과라는 오개념을 과학적 개념으로 바꾸는데 중요한 역할을 하였다. 닫힌 회로에서는 전구 양단에 쌓이는 전하들의 분포를 강조함으로써 회로에서 전류가 소모되지 않고 일정함을 이해하게 되었고, 직렬과 병렬에서도 각 회로에서 전구 양단의 전하들의 분포를 고려함으로써 회로에 따라 전지의 역할이 달라짐을 이해할 수 있게 되었다.

In this study, we investigated the characteristics of elementary school teachers' self-images of science teaching by using Draw-A-Science-Teacher-Test Checklist (DASTT-C). A survey was administered to 178 elementary school teachers in Seoul, Gyeonggi province, and Gangwon Province. It was found that elementary school teachers' self-images of science teaching for four science subjects (physics, chemistry, biology, and earth science) were more 'teacher-centered' than 'student-centered'. The results may imply that elementary school teachers' beliefs of science teaching tend to be more traditional than constructive. Therefore, there is a need to develop an effective education system for pre- and in-service elementary school teachers based on constructivism.

The purpose of this study was to provide fundamental data and implication for forming desirable viewpoint of mathematics lesson critique and for improvement of expertise in lesson by compare and analyze the viewpoint of mathematics lesson critique of pre-service and in-service teachers. For the achievement of the purpose, The lesson critique materials of each 25 pre-service and in-service mathematics teachers were collected and arranged, and compare and analyze the viewpoint of mathematics lesson critique of pre-service and in-service teachers by using the standard for analyzing viewpoint of lesson critique composed of two categories, five main codes and 18 sub codes. The results of this study, both pre-service and in-service teachers have tendency for criticising lesson focusing on the practice rather than plan of lesson and both pre-service and in-service teachers showed evaluative reaction in most of critical statements and used positive ones rather than negative ones. The only pre-service teachers, though minor of them, showed non-evaluative reaction in criticising class and most of the statements were just description and explanation without any their own judgement for the scenes and activities of lessons and most of pre-service teachers have tendency to include reflection and introspection for their own class in lesson critique.

The purpose of this study was to analyze the perceptions of creativity in mathematics of preservice elementary school teachers. Creativity in Mathematics is one of the most important components in mathematics teaching and learning, which has been emphasized in the Principles and Standards for School Mathematics and the 2009 Revised Mathematics Curriculum. For this study, the researcher analyzed reports of creativity in mathematics in mathematics lessons from the perspectives of 55 preservice elementary school teachers. The preservice teachers observed 55 mathematics lessons focusing on creativity in mathematics during their two-week-student-teaching period. The results showed the followings. First, the preservice teachers had a narrow perceptions on creativity in mathematics. Second, observational experiences of mathematics lessons led the preservice teachers to reconsideration of creativity in mathematics. Third, the preservice teachers provided a various strategies to enhance students' creativity in mathematics. The researcher suggested the followings. First, definitions and practices of creativity in mathematics should be included in the teacher education programs. Second, mathematics textbooks should include creativity in mathematics in a sophisticated manner. Third, creativity-rich materials should be developed and distributed to teachers. Finally, well-designed teacher training programs should be necessary.

The purpose of this study is to examine teachers' stages of concern and levels of use about SW education based on Concerns-Based Adoption Model and to provide implications for teacher education. For this purpose, 152 survey responses were collected from elementary school teachers in South Korea. The result indicated that elementary school teachers' concerns about SW education showed the nonuser pattern in that teachers score highest in stage 0(awareness) to stage 2(personal) and in stage 6(refocusing). Additionally, teachers who are currently implementing SW education showed a tendency to be in the level of mechanical use or routine, and more than half of the teachers who are not implementing SW education showed no motivation to change current practices. There were statistically significant differences in the stages of concern depending on gender, teaching experience, SW training experience, SW teaching experience, and there were differences in the levels of use depending on the teachers' grade level in charge, SW training experience, and SW teaching experience. Based on the results of the research, various SW related programs as well as successful SW education experience for teachers need to be provided for teacher education in order to promote SW education.

Students' interest and motivation of a lesson can be deeply influenced by how their teacher starts his or her lesson. So the introduction part of math classes should be very carefully and thoughtfully designed. The goal of this study is to serve the foundation for developing the practical types of introduction part of math classes and to draw the implications for planning and teaching math classes. For these, 19 lesson plans titled by 'volume of cylinders' composed by elementary teachers and 2 lesson videos on the internet are analyzed. Finally, seven types of introduction parts of math class are probed and several implications are suggested.

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.

Data science is a discipline comprised of the academic fields of statistics, computer science, information technology, and domain knowledge. It analyzes data and derives meaningful results using complex technologies. Data science, along with artificial intelligence, is a core technology of the 4th industrial revolution; consequently, universities and companies worldwide are actively developing programs to develop data scientists who require high levels of expertise. In line with this undertaking, the field of elementary education has recognized the importance of data science education and so various studies have been conducted to develop curricula designed to help students understand how to use data. This paper proposes a curriculum for the purpose of educating elementary school teachers who are mostly non-majors in the computer field about data science. Satisfaction analysis was conducted based on questionnaires collected from students to analyze the effectiveness of the data science education proposed in this paper.
