오늘날 교육현장에서는 교육 환경의 변화에 따라 수많은 교구들이 보급, 사용되고 있다. 특히 과학 교구의 경우 실험 실습의 중요성이 강조되면서 과학과에서 큰 비중을 차지하고 있고, 그 종류 및 수량 또한 다른 교구에 비해 많기 때문에 효율적이고 편리한 관리 도구가 필요한 실정이다. 본 논문에서는 이러한 요구에 따라 좀 더 편리하고 활용성이 높은 과학 교구 관리 시스템에 관하여 연구한다. 본 연구를 통해 현재 웹 표준으로 자리 잡고 있는 XML을 이용하여 누구나 쉽게 활용하고 공유할 수 있도록 하며, 이식성이 좋은 JAVA 언어를 통해 어느 환경에서든 이용할 수 있도록 하는 과학 교구 관리 시스템을 개발한다.

This study derived optimized teaching aids that use the physical computing method as the solution for effective software education at the elementary level. We set standard for selecting physical computing teaching aids in elementary-level by gathering the opinions from previous studies and think tanks and then applied the standard to some aids and choose one. We also made lesson plan and tried it to the experimental group. Subsequently, students' logical thinking skills showed a statistically significant improvement in terms of the t-test. Also, in the analysis of the effect size, it was shown to have a positive influence on the improvement of the students' logical thinking skills. Additionally, survey of satisfaction evaluation from the students showed that the teaching aid selection standard was effective in selecting suitable teaching aids for elementary students and that the classroom activities utilizing physical computing teaching aids were at a suitable level for elementary students.

대부분의 수학 수업이 알고리즘을 숙달시키고, 기계적으로 익힌 절차에 의해 정답을 맞추는 것에 중점을 두어 왔기 때문에, 학생들은 수학은 딱딱하고 어렵고 재미없는 과목이라는 인식을 많이 하고 있다. 그러나, 수학 수업에서 수학 교구의 조작 활동을 한다면 수학적인 흥미를 유발할 수 있을 뿐만 아니라 추상과 형식적인 수학으로의 발달을 돕고 학생들이 활동적으로 수업에 참여할 수 있게 된다. 이러한 맥락에서 제 7차 교육과정의 '도형'영역에서는 조작 활동을 통한 자기 학습능력 개발에 중점을 두고 주위의 실제 생활에서 볼 수 있는 사물을 관찰하여 그 성질을 추상해 낼 수 있도록 구체적인 교구를 이용하는 조작 활동을 강조하고 있다. 본 연구에서는 이러한 관점에서 정규 수학 수업이 아닌 일선학교의 클럽 활동 시간을 이용하여 학생들이 수학 교구를 충분히 조작하고 활용할 시간을 제공하며, 학생들이 수학 교구의 조작 활동을 통한 클럽활동이 학생들의 수학적 성향 및 능력 수준에 따른 도형 학습능력에 어떠한 변화를 미치는 지를 사례를 중심으로 논의하고자 한다.

The purpose of this study was to analyze the effects of using the geometric manipulative for the development of spatial sense and thus to find out a better mathematics teaching and learning method that could help develop students' spatial senses. The two fifth grade classes were randomly chosen as an experimental group (31 students) and a control group (32 students), respectively. This study implemented nonequivalent control group pretest-posttest design of quasi-experimental design. The test instrument used in this study was a spatial sense test. The pretest and posttest were implemented with the same instrument. In addition, their classes were observed and videotaped, and the data and their study activities were analyzed. In conclusion, first, the geometric manipulative-aided activities contributes to developing students' spatial senses and their two sub-factors involves perceptual consistency and perception of spatial relationship. Second, the activities of grasping the components of solid figures, sketches and development figures by using the geometric manipulative contribute to boost students' perceptual consistencies and their perceptions of spatial relationship.

본 연구는 지능정보기술을 천문교육에 활용하여 어떻게 천문교육에 활용할 것인가에 대한 방안을 모색해보았다. 3D프린터, 레이저커팅기, 빅데이터, 인공지능, 드론 등 지능정보기술을 확보한 메이커스페이스 공간에서 이들 기술을 활용하여 천문교육 프로그램을 개발해보는 일은 4차산업혁명시대의 핵심역량을 함양하는데 크게 기여할 것으로 판단된다. 또한 2021년 8월에 중기부 사업으로 선정된 충북대 Pro 메이커스 센터를 중심으로 메이커스페이스 환경에서 다양한 천문교구 개발 및 개발된 천문교구를 활용한 프로그램이 개발되어 형식교육의 현장 뿐만 아니라 비형식 교육의 현장에 다양하게 적용될 계획이다. 이에 향후 메이커스페이스 환경에서 대중천문프로그램이 어떻게 발전될 것인가에 대한 견해 및 토론도 발표될 예정이다.

The object of this study is to analyze manipulative materials in the Pattern & Algebra field of Maths300-Maths with Attitude, Australian school mathematics program with manipulative materials to search meaningful ways for school mathematics. To accomplish these projects, 20 manipulative materials in the Pattern & Algebra field of the Maths with Attitude are introduced and each manipulative materials can be used are searched according to grades and fields of Korean educational course. And 4 mathematics classes for 3rd and 5th grades(two for each grades) with manipulative materials are performed and effect of these classes are examined by recorded data and students' opinions are inquired by questionnaire. First, We analyze Pattern & Algebra of the Maths with Attitude 20 manipulative materials such as 4ARM SHAPES, ADDITION TOTALS, ICE CREAM FLAVOURS, THE LAND OF ET, etc. In this analysis, plans for utilizing the manipulative materials are categorized in 9 types. Second, by students' handling these kinds of manipulative materials in classes, their interest in mathematics is increased and voluntary and creative classes out of the conventional ones can be made. Also, students' self-confidence in mathematics and active participation is animated. This kind of manipulative materials are introduced in the educational field of elementary schools, plans for utilizing the teaching aids in the field are analyzed, the teaching aids are practically applied to classes, and the effect and meanings for mathematics classes are examined. With this research, another researches about the introduction and utilization of other various manipulative materials for motivating students to efficiently understand what they learn in mathematics class of elementary schools are required.

This study aimed to confirm that the lateral lines of fish indicate water temperature, water pressure, water flow, and sound waves by conducting a direct experiment. To confirm the superiority of fish lateral lines to detect material stimuli after the experimental study of the fish lateral line's sensation function, the lateral line's tissue was expanded and the shape of the lateral side of the fish was created using a 3-D printer to realize the lateral stripe parity. The amplification effect was confirmed by measuring the sound waves, which was the material stimulus of the lateral diagonal parabola. This proved that fish lateral lines are biotechnologically superior sensory organs.

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.

Although education using teaching tools is important to both students and teachers, the quality problem of distributed teaching tools is constantly being raised. Therefore, the purpose of this study is to analyze the teaching tools by classifying them into three quality factors, and to confirm the satisfaction and repurchase intentions of elementary school teachers. This study was conducted by dividing the first CIT survey and the second survey targeting incumbent elementary school teachers, and the PLS statistical program was used as an analysis tool. Through empirical analysis, it was analyzed that product quality, educational quality, and service quality had a positive (+) effect on teacher satisfaction, and that teacher satisfaction had a positive (+) effect on repurchase intention. Through this, it gives teachers insight into what they should focus on when purchasing or evaluating teaching tools and how to use them usefully for education, and for researchers, it provides an important clue to research for product quality improvement, and for companies that produce and distribute teaching tools, it gives to effective guidelines for the development of new products and contents. In the future, in addition to the relationship between the teaching tools and teachers, additional research on the organic relationship between the teaching tools and various objects is needed, and this is suggested as a future study.
