Currently, general educational science experiment teaching aids cannot be accurately measured, and even MBL experiment teaching aids consist of sensor-oriented programs that is difficult to actively design experiments by focusing only on securing data. This study envisioned a science experiment parish system capable of software convergence experiment design through curriculum analysis, and designed the entire system architecture, frame, and mechanism of MBL-based science experiment parish system by supplementing the limitations of the existing experiment.

Lately, as the importance of software and the software education has been emphasized, the studies on ways of teaching programming to elementary students have been actively progressed. However, most of undergraduates as prospective elementary teachers who will be in charge of teaching programming at the elementary schools have a lack of interest in programming education as well as of the understanding of basic programming principles. Therefore, this study investigated how programming education using hands-on robot and scratch affected learning motivation and academic achievement of preliminary teachers. The comparison of results of two programming educations shows that the programming education using hands-on robot revealed statistically significant difference in learning motivation and academic achievement.

As the importance of software education is emphasized, various educations for improve the computational thinking of elementary school students are being provided. However, there are many limitations that apply to the school at preceding studies. because they were invented for specific environment or students. Therefore, in this study, software education was conducted by constructing teaching-learning activities in consideration of the characteristics of students such as teaching aids and level of computational thinking ability, which can influence students based on the contents of textbooks. Through the comparison about computational thinking improvements, this study tried to suggest the direction of effective software education method. As a result, there are differences in computational thinking improvements according to the student's level and used teaching aids. Specifically, visual programming and unplugged type teaching-learning activities were more effective in teaching aids, and according to the level of students, students with low level of computing thinking in pre-inspection showed relatively high improvement. This tendency suggests that it is necessary to consider various learning factors in designing teaching-learning activities in elementary software education.

The purpose of this study is to compare and analyze the effects of physical manipulative and exploratory geometry software on the spatial sense for 5^th grade elementary school students in learning nets. For this purpose, ton experimental group used Geofix, an operational learning tool, and the experimental group used Cabri 3D, an exploratory geometry software to learn the nets of solids. The comparison group was learned by worksheet only without any manipulative or software. Spatial sense tests were conducted before and after to determine the level, and eye tracking were used to analyze the strategies of students in solving nets problems. As a result, it was confirmed that the using Geofix group was the most effective for the spatial sense, and Cabri 3D could also be a good tool for learning the nets of solids. In addition, after learning the nets of solids, the analytical strategy, which was the most effective strategy for students' solving strategies, increased. In the process of solving spatial tasks such as the spatial sense tasks, eye tracking technology become a very useful tool for exploring students' strategies, so it is expected that objective and useful data will be collected through more active use in the future.

인공지능 기술의 발달과 함께, 4차 산업 혁명에 관한 사회적 논의가 이슈화됨에 따라 교육 학계도 변화의 목소리를 높이고 있다. 지식기반 사회에서 컴퓨터 활용 역량이 강조되면서, 코딩/소프트웨어 교육 등 테크놀로지 기반 교수학습이 교과목과 관계없이 주목받고 있다. 최근에는 오픈소스를 만드는 사람들에 대한 긍정적 인식이 생겨나면서부터, 그들을 메이커라 지칭하고 메이커를 양성하기 위한 운동이 확산되기 시작하였다. 학계에서도 이 운동을 수용하려고 시도하였으나, 관련 연구에서는 기존 테크놀로지 기반 교수학습과 구분되는 특성을 명백하게 보여주지 못했다. 본 연구는 메이커 교육의 시론적 연구로서, 이재호와 장준형(2017)이 제안한 메이킹 역량을 중심으로 이를 키워줄 수 있는 피지컬 컴퓨팅 교구를 조사하였고, 동시에 활용 가능성을 제안하였다. 초기에 제안된 교구의 활용방안은 현장 교사 3인의 전문가 검토를 받았으며, 그들이 제공한 조언을 참고하여 수정하였다. 보완된 활용방안은 메이킹 역량을 구성하는 분석역량, 설계역량, 구현역량으로 구분하여 제시하였다. 이를 통해 메이커 교육의 이론적 발전과 확산에 기여하고자 하였다.

초, 중, 고 정규 교육과정에 피지컬컴퓨팅 단원이 포함 되었고 교구 지향적인 특성을 갖는다. 피지컬 단원을 위해 매우 다양한 교구가 출시 되고 있으나 학생들의 창의적인 아이디어를 모두 수용 가능하며 저렴한 교구는 찾기 힘들다. 저렴하고 막강한 기능을 가진 아두이노가 최적의 보드이지만 어려운 하드웨어 세팅과 텍스트 코딩 기반이라 외면 받고 있다. 또한 블록코딩이 가능하긴 하나 단순한 디지털, 아날로그 센서 제어 명령만 제공하다 보니 다른 보드와 기능적인 차이는 없으면서 하드웨어 세팅만 어렵게 느껴진다. 아두이노가 가진 다양한 입, 출력 모듈을 제한 없이 사용 가능한 장점을 훼손하지 않으며, 코딩이 쉬우려면 센서 제한 없는 블록코딩이 되어야 한다. 만약 아두이노가 하드웨어 세팅이 쉬우면서 거의 모든 입출력장치를 블록명령으로 제어가능하다면 초중고 학생들이 자신의 아이디어를 제한 없이 구현하여 창의적인 작품을 만들 수 있을 것이다. 따라서 블록코딩으로 아두이노의 막강한 기능을 제한 없이 사용하기 위한 방법을 연구하고, 해결책을 찾아 제시한다.

교구로봇' 교육은 영재교육과 경진대회를 통하여 초등학생과, 학부모, 교사에게 기대와 인식이 매우 보편화 되었다. 또한 창의성과 통섭교육에 대한 관심이 높아짐에 따라 초등학교 방과후 교실의 로봇교육은 더욱 증가할 것으로 보인다. 그러나 방과후 로봇 교실 운영에 대한 초등현장의 교구로봇 교실 운영 실태조사가 이루어지지 않고 있을 뿐만 아니라 지도교사 양성이나 체계적인 프로그램 운영 관리가 부족한 상황이다. 따라서 본 연구에서는 초등학교의 방과후 '교구로봇' 교실 운영실태 및 교사의 인식을 조사하여 문제점을 파악하고, 보다 바람직하고 효율적인 방향으로 방과후학교 로봇교실이 정착될 수 있도록 시사점을 제공하고자 한다.

The purpose of this study is to investigate the effect of observing material on the phase change of moon considering the orbits of earth and moon for elementary school students. For this study, the material which shows the orbit of moon tilted at $5^{\circ}$ with the orbit of earth is developed. 110 6th grade students in an elementary school are sampled. They are divided into the experimental group and the control group. The lessons using the material developed in this study are implemented to the experimental group, and the lessons using the material proposed in ordinary textbook are implemented to the control group. The pre, post, delayed concept tests on the phase change of moon are administered to the students of the experimental group and the control group, and semi-structured interviews are conducted for each concept level. According to students' responses, the concept levels are divided into 'Phase recognition', 'Space viewpoint', 'Earth viewpoint', and 'No recognition'. The experimental group and the control group are homogeneous in the pre-test. The result of this study shows that the experimental group gains significantly more scores than the control group in the post and delayed tests. Also, in the post and delayed tests, more students of the experimental group are in the highest level 'Phase recognition' than the control group. Finally, students of the experimental group who were in the 'Phase recognition' and 'Space viewpoint' explain more scientifically than the students of the control group. Therefore the results of this study show that the observing material on the phase change of moon considering the orbits of earth and moon is effective.

In this study, I investigated prospective mathematics teachers' perceptions of activities using Wax-paper, a hands-on material (manipulatives), and GeoGebra, a technological tool, in teaching quadratic curves. Twenty prospective mathematics teachers in the Mathematics Education Department of a local university participated in a survey on their perception of the use of hands-on materials and technological tools in teaching quadratic curves. According to the results of this study, prospective mathematics teachers generally preferred the use of technological tools for learning and teaching quadratic curves. Additionally, mathematics teachers thought that the tool helped students develop intuitive thinking through visualizing quadratic curves, enabling the exploration of various mathematical properties, assisting the comprehension of various concepts, and increasing students' interest levels. However, they were concerned about the immature use of technological tools by students or teachers, and recognized that the advantages and disadvantages of using hands-on material and technological tools were complementary. Based on these findings, it is suggested that hands-on material and technological tools should be used complementally in mathematics classes, and the development and dissemination of class materials that are not affected by students' or teachers' ability to use technological tools is important.

저학년 학생에게도 적절한 표상이 제공되기만 하면 고등 지식을 수용할 수 있다는 사실은 브루너(J.S. Bruner)의 EIS 이론에 의하여 뒷받침 될 수 있다. 이를 위해서는 구체적인 조작이나 시각적인 표상이 제공되어야 한다. 그러나, 실물로써 교구를 제시하는 것은 현실적으로 많은 제약이 따르므로 그 대안으로 컴퓨터 환경에서 제공되는 조작 도구들을 고려해 볼 수 있다. 인터넷 환경은 접근에 있어 용이하며 별도의 비용이 필요 없고 업데이트가 용이하다는 장점을 가지고 있으므로 교구로써의 장점을 갖고 있다. 이에 따라 인터넷 상의 조작 도구를 통한 수학교육 프로그램을 개발하고자 한다.
