Since elementary students are in the concrete operational stages, they have to learn mathematics using intuitive methods such as visualization, observation, operation, experiment instead of formal approach. For this, we should present the various intuitive methods in curriculum and textbook. It is because that curriculum and textbook are important tools to students when they study mathematics. So, this paper intended to analyze the instructional content by intuitive principle in elementary mathematics curriculum, textbook and curriculum guide. The results are as follows: there is an intuitive principle in only character of mathematics in curriculum. I can't find the intuitive principle in other areas in curriculum. There are 12 intuitive principles in figures area, 1 in measurement area, and 2 in probability and statistics area in curriculum guide. But intuitive principles which are used are inclined to restricted to intuitive principle via representation obtained in the usual experience. Finally, I suggest some implications about teaching via intuitive principles, curriculum, and writing textbook based on the this findings.

This study classified the visualization's materials presented in two types of middle school science textbooks to data visualization and infographics, thereafter characteristics of infographics according to science content's domains were analyzed using an analytical framework for infopraphics. The results of this study are as follows : First, visualization materials in middle school science textbooks had more data visualization (23.2%) than infographics (76.8%). Second, there were many differences in information content's category among the science subject's domains. The relationship type of information content in the domain of energy and matter, the function type in life domain, and the location type in the earth domain were prominent. In visual representation's category, the illustration type and comparative analysis type were the most dominant in the all science domains. The horizontal type in layout category occupied the largest proportion in all science domains. Therefore, it is necessary to present the visualization materials with the infographics conveying many informations than the data visualization in middle school science textbooks. And the infographics need to be developed and distributed in various formats in each science domain.

국가 교육과정에서 컴퓨터 하드웨어만을 교과 내용으로 하는 최초의 과목은 4차 교육과정 시기 중공업 계열 고등학교에 신설된 '전자 계산기 구조' 과목으로 현재의 '컴퓨터 구조' 과목에 해당된다. 컴퓨터 구조 과목의 교과 목표는 학습자가 컴퓨터의 구조와 동작 원리를 바르게 이해하고 컴퓨터를 효율적으로 활용할 수 있도록 하는데 있다. 교과 목표를 위해서는 교과서의 내용이 정확해야 하고 현재의 컴퓨터 구조를 바르게 반영하고 있어야 한다. 본 연구에서는 공업 계열 고등학교의 컴퓨터 구조 과목에 제시된 연산 장치 영역 내용의 문제점을 컴퓨터 구조 전문 서적과의 비교를 통해 파악해 보고자 하였다. 연구 결과, 교과서의 연산 장치 영역에는 정확성과 일관성이 결여된 개념 정의와 현재의 CPU 구조를 반영하지 못한 내용이 포함되어 있었다. ALU와 연산 장치에 대한 설명이 교과서별 상이하였고, 연산 장치의 구성 요소들은 현재 사용되고 있는 CPU 구조를 바르게 나타내고 있지 않았다. 이러한 문제점들은 컴퓨터 과학의 역사적, 기술적 고찰을 통해 개선될 필요가 있다.

This study aims to develop the content structure of healthy dietary education for multicultural family parents who guides their children to the correct and desirable applications at home. This study is an exploratory study intended to establish the contents of healthy dietary education for multicultural family parents. For the methodology we investigated dietary behaviors of children of multicultural families. As a result of examining closely the necessity and contents of healthy dietary education for the multicultural families parents including food safety, nutrition, and food culture. Based upon the above findings, the goals of healthy dietary education for parents were set up, its content area and sub-area(education topics) were composed and fixed, and finally, topic-specific goals and 12 content elements were extracted, detailed and systematized for pre schoolers and elementary school children.

Growing in its size, the contents of the teaching-learning programs for mathematically gifted children from A program in Seoul Metropolitan Office of Education were examined in terms of the individual subjects provided through the courses of gifted education programs, and it was evaluated based on the revised version of the existing module. As a result, the educational objectives of teaching-learning program were clear, differentiated and obtainable. Among the program, the advanced parts were more than the selective parts, which mainly consisted of numbers and calculation, shapes, regularity and problem solving parts and had latest contents of research in balance. Additionally, every part of the program needs mathematical and creative thinking and approach and has proper evaluation index for problem solving. The presented materials in the programs are specific and appropriate, though some of them did not suggest the evaluation index for cultivating personality and value clearly and the reference books. The teaching-learning programs were focusing on problem-based learning and cooperative learning and using performance assessment for evaluation.

The purpose of the study was to investigate the professional level of the Korean non-physics major middle-school science teachers in 'force and motion' content knowledge. For the study, nine science teachers who majored in chemistry, biology, or earth science were sampled from middle-schools in a big city in Korea. The physics concept test-tool (subjective type), which the authors developed, were administered, and then followed by in-depth interviews. The research findings are as follows: Firstly, non-physics major science teachers' correct answer rate in physics knowledge test of secondary school level was not so high that they may have difficulty in teaching correct concepts in physics to middle-school students. Secondly, some teachers show that they can not apply some physics concepts from one to another situation. That means that they may have difficulty in teaching physics conceptual application in various situations to students.

This study aimed to investigate technological pedagogical and content knowledge(TPACK) model, and to apply this model to preservice education. To perform this study, TPACK survey instrument was distributed to 142 preservice teachers who took technology integration course. The result showed that technology and content knowledge improved significantly, and pedagogical and pedagogical content knowledge did not show meaningful differences among 7 sub-categories. Based on the result of this study, we discussed the improvement of technological and content knowledge, and pedagogical knowledge. Also, we suggested that (preservice) teacher education should consider the combination of technological, pedagogical, and content knowledge in Korea.

The STS contents, emphasized in the 6th curriculum, in the chemistry textbooks(II) were analyzed. The STS contents in textbooks showed average value of 2.7%. The chapter of ‘chemical bond and compound' were included 3.8% of STS contents. And the chapter of ‘atomic structure and periodic table', ‘state of material and solution', ‘science of material', and ‘chemical reaction' contained 3.2%, 2.2%, 1.9%, and 1.9% of STS contents, respectively. When the STS contents were analyzed by STS topics of Piel, the results are as follows; 33.7% on effect of technological developments, 27.5% on environmental quality and utilization of natural source, 19.6% on human engineering, 13.8% on energy, and 5.4% on sociality of science. However, there were no topics on population, space research and national defense. When the STS contents were analyzed by student activities of SATIS, most of the activities were research and case study. There were few field activities of practical investigation, problem solving and decision making, research design and stimulation. There were no activities of role play.

The goal of this study is to investigate the features of Korean eighth graders' achievement and its trend in Chemistry in TIMSS 2011 and TIMSS 2015, and to explore its implications for Korean science curriculum and in teaching science. With three science educators and six science teachers, we analyzed the characteristics of Korean eighth graders' achievement in Chemistry by test-curriculum matching analysis. According to the trend analysis of science topics with released items for Chemistry in TIMSS 2015, Korean students' percentage for correct answers has dropped in topics such as regularities in chemical reactions, oxidation-reduction, etc. since these topics are covered after the ninth grade in the 2009 revised curriculum. For science cognitive domains, Korean students showed weaknesses in 'applying' domain in TIMSS 2015. Based on the results, we suggested implications for improvement in middle school chemistry curriculum and how to improve science teaching and learning for students' better science competencies and real-world application of science knowledge.
