The purpose of this study is to derive ways to support Integrated Science curriculum implementation by evaluating the results of Integrated Science teacher training programs conducted by the Ministry of Education to support the settlement of 2015 revised Integrated Science curriculum. Teachers' output from the teacher training programs and interviews with training instructors in the 2017 Integrated Science Leading Teacher Training program were analyzed to derive the features of the Integrated Science curriculum and support plans for the implementation of Integrated Science in schools. Teachers who participated in the 2017 Integrated Science Leading Teacher Training program developed teaching, & learning and evaluation plans through participatory training sessions, where the achievement standards most selected by teachers were [10IS08-03] and [10IS09-04]. Through the text mining analysis of these achievement standards, we explored the implementation realities such as reconstruction of achievement standards, teaching and learning methods, learning materials, evaluation methods, and subject competencies. In addition, we analyzed exemplary reconstruction models of achievement standards in light of best integrated instruction, student-participatory instruction, and developing science competencies. Based on the results, we propose teacher training support plans and further studies for the implementation and settlement of the Integrated Science curriculum.

The purpose of this study is to obtain implications for the improvement direction of astronomical education methods and development of educational materials or software. In connection with the 5th grade 1st semester elementary science 'Solar System and Stars' unit, elementary pre-service teachers were given a reorganization task to compare the relative distances from the sun to the planets, and then this was analyzed. Pre-service teachers are 11 male and 19 female students in the second year of the music education department at the elementary school teacher training university in B city. The implications of the study results are as follows. First, the 'distance comparison activity using a roll of tissue paper' is suitable for simply comparing the distances from the sun to the planet, but it has limitations in allowing students to experience the vastness of the solar system or inducing student participation-centered classes. Second, it is necessary to develop software materials for elementary school students that can simultaneously reflect the size of the planet and the distance to the planet that can be applied indoors, and also experience the vastness of the solar system, as well as a wide learning space. Third, textbook materials for students have an important influence on the class design of pre-service teachers.

대전국립중앙과학관의 천문영역 전시가 Booth et al(2008)의 논증을 기초로 한 과학철학 측면에서 얼마나 잘 부합되는지 확인하는 것이 이 연구의 목적이다. 과학관은 비형식 교육기관 중 하나이다. 과학관의 전시물들은 관람자들에게 정보를 전달하고, 관람자들은 전시물들을 통하여 지식을 탐구한다. 그러므로 교육적 상호작용을 뒷받침하는 이론적인 기준이 필요하다. Booth et al(2008)이 주장한 논증모형은 관람객의 심리적인 진행과정을 고려한 과학철학이다. 그렇기 때문에 과학관 전시에 Booth et al(2008)의 논증이 적용된다면, 관람객들은 전시물들이 의도한 지식을 스스로 탐구 할 수 있다. 김정엽(2011)은 Booth et al(2008)의 논증을 이용하여 과학관 천문영역 전시형태를 재구성하였고, 대학생들을 상대로 설문 조사와 SPSS 통계 분석을 수행하여, 재구성한 전시형태가 정보전달과 지식 탐구 관점에서 기존보다 더 설득력 있음을 보인 바 있다. 최근 대전국립중앙과학관은 천문영역 전시를 개선하였다. 그러므로 개선된 전시가 Booth et al(2008)의 논증을 기반으로 한 기준에 적합한지를 재분석할 필요가 있다. 분석 결과, 거시적인 전시형태는 이전에 비해 큰 변화를 보이지 않았으나, 미시적인 전시내용은 상당히 많은 부분에서 개선이 있음을 확인하였다. 그 자세한 분석 내용과 결과를 논의한다.

This paper compared and contrasted the views of effective mathematics instruction by 223 elementary school teachers and 151 middle school mathematics teachers using a questionnaire with 4 main domains (i.e., curriculum and content, teaching and learning, classroom environment and atmosphere, and assessment) and a total of 48 sub-elements. The analysis of results showed that elementary school teachers put their priority on the curriculum and content domain, while middle school counterparts did on the teaching and learning domain. The teachers commonly agreed with instruction which fosters students' self-directed learning ability, reconstructs the curriculum tailored to students' diverse levels, and establishes appropriate interaction between the teacher and students. However, elementary school teachers agreed more than middle school teachers with regard to the 23 elements related to effective mathematics instruction. In contrast, middle school teachers agreed more than their counterparts as for only 2 elements (instruction fostering mathematical representation and instruction eliciting students' learning motivation). This paper includes suggestions and implications related to Korean teachers' perception of effective mathematics instruction.

The purpose of this research was analyzing pre-post change of concept recognition structure about happiness and activity in which medical school students feel happiness, in order to develop such curriculum accordingly. Research subjects included a total of 36 sophomores attending medical school, and a day reconstruction method and network analysis were applied. According to the research finding, while medical school students were experiencing a lot of happiness while eating/talking and doing leisure activities, the frequency of feeling happiness through learning activities was shown to be low. Words that expressed happiness before and after were similar in many parts and 'economy' showed the highest degree centrality before and 'work' showed the highest degree centrality after. Because the structure of the concept about happiness was divided from 1 group into 4 groups including one's work, positive self, health of family, value about life etc., perception of the concept about happiness was changed from the concept about superficial happiness to the concept about actual happiness. Therefore, in order for prospective doctors who will treat human health to establish the concept and value about happiness properly, education about happiness is necessary and for this, curriculum related to happiness must be developed systematically.

This study investigates the effect of play-based software education instruction strategy for improving computational thinking as a method of software education. The play-based instruction strategy is a teaching-learning strategy in which the presented code is navigated through play, and the functions are revised and newly reconstructed. We designed an education program with the play-based instruction strategy and applied the program to elementary students. In order to verify the effectiveness of the research, we examined the competence of computing thinking concept and computing thinking practice. As a result, the computing thinking concept and computational thinking practice were that the proposed teaching-learning model is higher than the direct teaching method.

The 2015 Revised National Curriculum emphasizes software education to develop creative and convergent talents in preparation of the Fourth Industrial Revolution. Accordingly, it is necessary to develop competency-based training programs for informatics teachers in a rapidly changing educational environment. In this background, this study selects a framework to analyze the content of in-service training for informatics teachers through review of previous studies. By analyzing the current training programs to strengthen competencies required for informatics teachers in secondary schools, the study aims to develop implications for future in-service training programs. To this end, the study conducted a questionnaire survey of experts who participated in the development of in-service training textbooks and consulted them, then analyzed the elements of competency-based training program content and the relative importance of each competency element using the analytical hierarchy process (AHP). According to the results of the analysis, the content was relatively concentrated on the competency of "Understanding and Reconstructing the National Curriculum" required for general and informatics teachers as well, which accounted for 47% of all, or 7 hours out of the total 15 hours. In contrast, the content structure lacked the competency of highly relative importance by competency element "Establishing and Using Teaching-Learning Strategies for Informatics," which took up the highest portion of 27%. These findings will be used as basic data for understanding and reflecting the areas that fall short of the development of in-service training programs for informatics teachers.
