This study aims to discover how self-esteem and social competence in early childhood affect school adjustment in elementary school. This study used the 7th year (2014) and 10th year (2017) of the panel study on Korean children, which are longitudinal research data from the Korea Institute of Child Care and Education (KICCE). Pearson's correlation analysis and hierarchical regression analysis were used as the main statistical analysis methods. The analysis was performed using the the Spss 21.0 program. As a result of this study, peer acceptance among early childhood's self-esteem, assertion, cooperation, and self-control among social competence have influences on adjustment to elementary school life. This study is meaningful in that it is a longitudinal study conducted with a time difference for 3 years with the same subjects in order to investigate the influence of the inner factors of early childhood on school adjustment in elementary school.

The cam is used to a main component in a variety of automatic machines and instruments. To meet the demand of a complicated operation and of reducing weight for automatic machine, Curve Blending Technology, in which each of the basic curves suitable for individual interval is connected, is used for the cam design. In the curve blending, it is necessary to select appropriate elementary curve for each interval and to confirm the dynamic continuity at connecting points between adjoining elementary curves. This paper represented the elementary curve selection method to select an appropriate curve for each interval, and executed computation for the follower displacement and angular displacement of each interval. The paper made an analysis and examine closely for elementary curves to synthesizing curve blending, and it performed dynamic conditions clearly at every points on the cam motions. Therefore the curve blending technology presented by the paper turned into easier work.

With the development of science and technology, an effort to investigate the current research trend of elementary science education will lead to future directions for elementary science education. This study set out to analyze papers published in Elementary Science Education by quantity, subject and methodology for the last ten years. The results were as follows: First, the number of papers has continuously increased for the last 30 years. Second, as for categorization by the functions of elementary science education, the number of papers was mainly published in the field of teacher education, which was followed by learning processes and teaching methods in the order. Third, in the field of the research subjects of elementary science education, many researches were conducted on scientific inquiries and concepts traditionally emphasized in elementary science education, and on gifted education recently implemented as part of national policy. Fourth, as for categorization by the methodologies of elementary science education, a survey study was the most popular, being followed by experimental study and literature study in the order. In recent years, researches based on the case study methodology have visibly grown in numbers, which seems to part of efforts to find implications with new methodologies among researchers facing limitations with the old ones in the middle of uniqueness called education.

The purpose of this study is to provide basic data and guideline to STEM(Science, Technology, Engineering, Mathematics) educators who prepare engineering education in elementary and secondary school. For this, this study develops a composition model for engineering education program of elementary and secondary school. To do this, a literature research, experts interview and Delphi survey were conducted. Through the literature research, we extracted the components of model for engineering education program of elementary and secondary school and then made a first draft of the model. The draft was revised by experts while Delphi survey was used to validate the model based on Delphi panels' opinions. The panels for the Delphi survey consisted of 51 experts in the STEM education field. The survey was conducted three different times and importance survey was included in the third stage. The conclusions of this study were as follows: First, the model consist of definition, 4 directions, 4 characteristics, 3 educational goals according to school level, educational contents area and element, teaching and learning method and evaluation method. The educational contents area and element consist of 2 major areas, 7 areas and 18 elements. Second, all components of the developed model were valid in most of the statistics such as mean, standard deviation, the degree of consensus and convergence, and CVR(Content Validity Ratio). Third, importance for education contents area and element according to the school level are analyzed.

본 연구는 AI를 수학 수업에 사용하려는 초등학교 교사의 의도에 미치는 요인들에 대해 살펴보고 수학 수업에서 AI가 효과적으로 사용되기 위해 선행되어야할 요인을 제시하고자 하였다. 이를 위해 기술수용모델(Technology Acceptance Model)을 사용하여 초등학교 교사의 TPACK과 TAM 사이의 구조적 관계를 조사하였다. 그 결과, 초등학교 교사들의 TPACK은 인지된 사용 용이성과 유용성에 유의미한 영향을 미쳤다. 또한 인지된 사용 용이성과 인지된 유용성은 수학 수업에서 AI 활용에 대한 태도에 유의미한 영향을 미쳤다. 인지된 사용 용이성, 인지된 유용성, 태도는 수학 수업에서의 AI 사용 의도에 유의미한 영향을 미치는 것으로 나타났다. 이러한 결과는 초등학교 교사들이 수학 수업에서 AI에 대한 TPACK 역량이 높다고 인식할수록 수학 수업에서 AI를 사용하기가 더 쉽고 AI가 학생의 수학 학습 향상에 도움이 되는 유용한 도구로 인식할 수 있음을 의미한다. 또한 수학 수업에서 AI가 쉽게 사용할 수 있고 유용하다고 인식할수록 AI 사용 의도가 높아질 수 있다. 따라서 초등학교 교사들이 수학 수업에서 AI의 활용하려면 TPACK에 관한 지식 교육이 선행되어야하며, 수학 수업에서 AI 사용의 이점과 편리성에 대한 인식 개선이 함께 이루어져야 한다.

The purpose of this study is to investigate the features of inquiry activities using technology in the 2015 revised elementary science digital textbooks. For this, we analyzed the features of inquiry context and inquiry method presented in inquiry activities using three kinds of technology: Virtual experiment, virtual reality and augmented reality. As a result, firstly, the most common types of 77 inquiry activities were realistic type which shows the phenomenon actually and vividly as possible and realistic-abstract type which shows the phenomena with the abstract concepts. Second, the ways of using three technologies were different depending on the processes of inquiry and the sub-domains of science. For example, virtual experiment technologies were mostly used in the contents of physics and chemistry with the inquiry context of realistic-abstract type for investigating the relationship between variables of experiments and describing the phenomena mechanically. On the other hand, virtual reality and augmented reality techniques tended to be used more frequently in biology and earth science contents with the inquiry context of realistic type for observing and describing the phenomena. Finally, we discussed educational implications in terms of developing and applying technology-based inquiry activities.

In this study, we investigated the elementary school students' perceptions of the scientific and technological professions by using the 'drawing scientific and technological workplaces'. The subjects were 401 students of 4th and 6th grades at three elementary schools in Seoul. The results revealed that many students drew the interiors of laboratories or factories as scientific and technological workplaces, and explained the nature of the work- place, but students' images were superficial and general. Most students' drawings also exhibited the stereotypical images of science and technology as androcentric and negative perceptions. Students were mainly inclined to perceive that the works relevant to science were experiments, and the works relevant to technology were productions and repairs. Most students answered more than two examples of scientific and technological professions, but their responses were not various and were biased toward basic scientists, blue-collar workers, and repairers. Educational implications of these findings were discussed.

2005년 12월에 정보통신기술교육 운영지침의 개정안이 발표되었으나 아직도 학교 현장에서는 이와 같은 개정안의 내용에 따라 제대로 교육이 실시되고 있지 않다. 그것은 개정안의 내용을 담고 있는 교과서의 내용이 충실하지 못한 것도 하나의 원인이라고 할 수 있다. 본 논문에서는 2006년 6월 이후에 출판된 초등학교 컴퓨터 교과서를 분석하였다. 분석한 결과 많은 교과서가 정보통신기술교육 운영지침 개정안의 내용을 제대로 반영하지 않은 것으로 나타났다. 특히, "정보 처리의 이해"와 "종합 활동" 영역의 내용이 상대적으로 부실한 것으로 나타났다. 따라서 초등 컴퓨터 교육의 활성화를 위해서는 교과서 검정의 충실화, 컴퓨터 교육 전문가의 참여, 상세한 교육과정의 개발, 교사 연수의 실시 등이 꼭 필요하다.
