Currently, reflective teaching has been actively studied in terms of teachers' professional development relating to classroom instruction. The present study looked at, using the method of a case study, the differences between a novice and an experienced elementary school mathematics teachers' beliefs demonstrated during their reflective teaching. The findings of the study show that at the intial stage of reflective teaching, the novice teacher identified few errors during class and was not enthusiastic about applying the results of her reflective teaching due to lack of confidence. By contrast, the experienced teacher identified more errors during class than the novice teacher and had fewer reflections due to a sense of confidence. As the teachers' engagement in reflective teaching increased with time, they both felt the need for advice from experts on mathematics teaching and directed their attention to interactions with their students away from teacher-centered instruction. Further, the novice teacher engaged in more teacher-student interactions than the experienced teacher, and the experienced teacher increased the frequency of teaching reflection. Based on the findings, the article suggests a number of implications for the cooperative reflective teaching between novice and experienced teachers and the improvement of classroom instruction.

This study analyzed the difficulties and mathematical modeling knowledge improvement that an elementary school teacher experienced in modifying a mathematics textbook task to a mathematical modeling task. To this end, an elementary school teacher with 10 years of experience participated in teacher-researcher community's repeated discussions and modified the average task in the data and pattern domain of the 5th grade. The results are as followings. First, in the process of task modification, the teacher had difficulties in reflecting reality, setting the appropriate cognitive level of mathematical modeling tasks, and presenting detailed tasks according to the mathematical modeling process. Second, through repeated task modifications, the teacher was able to develop realistic tasks considering the mathematical content knowledge and students' cognitive level, set the cognitive level of the task by adjusting the complexity and openness of the task, and present detailed tasks through thought experiments on students' task-solving process, which shows that teachers' mathematical modeling knowledge, including the concept of mathematical modeling and the characteristics of the mathematical modeling task, has improved. The findings of this study suggest that, in terms of the mathematical modeling teacher education, it is necessary to provide teachers with opportunities to improve their mathematical modeling task development competency through textbook task modification rather than direct provision of mathematical modeling tasks, experience mathematical modeling theory and practice together, and participate in teacher-researcher communities.

Modern society has become a key factor in determining software competitiveness. Therefore, Korea has required more than 17 hours of software education per year in the actual course subject to the 2015 revised curriculum. In this paper, we analyzed the software related units in 6 kinds of textbooks of elementary school published based on '2015 revised curriculum' and tried to provide basic data for selection of textbooks related to software education in elementary school. As a result of the analysis, the 6 revised textbooks of 2015 appropriately reflected both 'understanding of software', 'procedural problem solving', 'contents of programming element and structure', and I was suggesting appropriate activities. Unit support materials use comics and illustrations to stimulate interest, supplement text, and deepen learning. Four kinds of textbooks provide additional information by presenting reading materials. However, in most textbooks, the proportion of learning using the appendix was low. Although it consists of units focused on knowledge understanding and practice, it can be a textbook that enhances students' interest and participation if they are made of software in daily life, problem solving by procedural thinking, and so on.

The purpose of this study was to examine the effectiveness of problem-based learning(PBL) of information communication ethics on the problem-solving skills of fifth- and sixth-grade elementary school students about information communication ethics and their attitude. The findings of the study were as follows: First, the PBL-based teaching materials for information communication ethics could serve to stir up the interest of students by letting them face problem situations caused by the disfunction of the information society. Second, a wide variety of teaching-learning activities including cooperative learning and discussion were implemented while the selected students performed the given problem-solving tasks, and the activities had a very good effect on PBL-based information communication ethics education. Third, PBL-based information communication ethics education could be one of effective ways to boost not only the problem-solving skills of students but the teaching interest and capability of teachers.

The purpose of this study is to investigate trends in research studies on scientific argument and writing in Korea. 118 research studies published from 2004 to 2013 have been collected and analyzed. Many of the research studies focused on developing teaching strategies, analyzing contents of scientific argument and writing, and effects on student learning. More than half of the studies were conducted with elementary and middle school students while studies with pre-service, in-service teachers or high school students were relatively rare. Most research studies were conducted within regular school hour context and participants were given relevant information/education prior to argument and writing activities. Many research have analyzed student growth in scientific attitudes and we would suggest that further studies should investigate student growth in scientific concepts, scientific inquiry, and critical thinking. The structure and process of argument or the content and form of writing have been analyzed. The quality of argument and scientific concepts embedded in argument and writing should be investigated more in future researches.

Purpose: This study examined the effects of nutritional education related to sugar in elementary school children on nutritional knowledge, attitude, and dietary behavior. Methods: A questionnaire survey on the knowledge, attitudes, and intake related to sugar was conducted on 572 students in grades 4-5, who were attending five elementary schools in Seoul and Gyeonggi-do. Results: Among the survey subjects, 270 (49.8%) were cognitive in education, and 302 (50.2%) were non-cognitive. The sugar-related knowledge score was 3.67 points in the cognitive education group, which was significantly higher than the 3.55 points in the non-cognitive group. The rate of checking the sugar content in the nutrition label was 31.2% in the cognitive education group, which was significantly higher than in the non-cognitive group, 15.4%. The cognitive education group had a higher intake frequency of unsweetened candy, jelly, and raw fruits, and higher sugar intake of unsweetened bread, white milk, and raw fruits than the non-cognitive group. In the case of the cognitive education group, the total knowledge score showed a positive correlation with the food behavior scores, and a negative correlation with the frequency of purchasing snacks after school, and the average sugar intake per day. In the cognitive education group only, the education of nutrition teachers was analyzed as a factor to reduce the total sugar intake. The cognitive group of sugar education tried to eat foods with a lower sugar content than the non-cognitive group, and nutrition education was an important factor affecting the sugar intake. Conclusion: To reduce the sugar intake of elementary school students, it will be necessary to practice oriented-nutrition education by nutrition teachers continuously. In addition, it is important to develop and disseminate various types of nutrition education materials related to sugar that can be utilized easily by nutrition teachers.

This study examines the employment conditions and labour experience of elementary after-school care teachers in South Korea. Based on the empirical data collected through in-depth interviews with after-school care teachers in Gwangju Metropolitan City, the study considers multifaceted problems faced by after-school care teachers in their workplace. The after-school care class is part of educational policies initiated and rapidly expanded by the Ministry of Education, resulting in the substantial increase of non-regular school workers. The irregularization of after-school care teachers illustrates that the common problems faced by female non-regular workers, such as social discrimination, exclusion and inequality, are also transplanted into the typical public sector. In the case of Gwangju Metropolitan City, during the past two years there have been evident increases both in under 15-hour short time contract care teachers and outsourcing of care classes. Temporary part-time contract care teachers suffer relentless job insecurity and experience poor working conditions, exclusion and discrimination within the workplace and labour alienation. In order to minimize the organized resistance of care teachers, school authorities implicitly individualize and isolate care teachers through hierarchization, the division of labour and the spatial division of classes between indefinite and temporary contract teachers.
