본 연구에서는 데이터 분석도구인 R을 활용하여 튜터링 학습법 참여 학생의 성취도를 검증하였다. 분석도구 R은 대용량 데이터의 고급 분석과 통계 계산을 위한 스크립트 언어로 빅데이터의 자료 분석에 다양하게 활용되고 있다. 대학의 학습 활동 측면에서의 튜터링 학습법은 학습 능력이 우수한 선배 또는 동료인 튜터와 학습 받고자하는 튜티가 1:1 또는 1:N의 관계를 이루고 학습 활동을 진행해 나가는 과정이다. 튜터링 학습법 운영 후 실시하는 참여 학생 만족도 조사 결과에 의하여 튜터링 학습법이 학력 수준 차이를 극복하는데 도움이 되고 있다는 정성적인 근거는 있으나 정량적인 분석 연구는 부족한 실정이다. 이에 본 연구에서는 튜터링 학습법에 참여한 공학정보학부 튜티들의 성적 결과를 분석도구 R을 활용하여 분석하여 튜터링 학습법이 학업성취도에 긍정적 영향을 미치는 것을 검증하였다.

Individual studying that compose knowledge and improve efficiency of studying through collection of information by various class strategy which takes advantage of web, and Cooperative learning that can elevate sense of responsibility and solve the problem through communication with another person have been developed actively. But, individuation tutoring materials that is developed present doesn't fit of causing learner's interest, and stimulating curiosity about problem because mostly studying is gone in presentation form. Also, cooperative learning materials are lacking connection with actual course of education, application is difficult in real class spot. So, this research has applied self-directed learning, centered with interested operation activity, aimed at improvement in various thought. Also, we have developed social studies tuition-learning system, purpose to the management is possible with on-line project studying which could improve mind-decision ability and ICT application ability. This system is developed for flexible management could be possible in various class circumstance, and level learning could be done through accomplishment-test and the result could be applied by feedback process.

To generate a deep learning model with high performance, a large training dataset should be required. However, it requires a lot of time and cost to generate a large training dataset in remote sensing. Therefore, the importance of transfer learning of deep learning model using a small dataset have been increased. In this paper, we performed transfer learning of trained model based on open datasets by using orthoimages and digital maps to detect changes of building objects in multitemporal orthoimages. For this, an initial training was performed on open dataset for change detection through the HRNet-v2 model, and transfer learning was performed on dataset by orthoimages and digital maps. To analyze the effect of transfer learning, change detection results of various deep learning models including deep learning model by transfer learning were evaluated at two test sites. In the experiments, results by transfer learning represented best accuracy, compared to those by other deep learning models. Therefore, it was confirmed that the problem of insufficient training dataset could be solved by using transfer learning, and the change detection algorithm could be effectively applied to various remote sensed imagery.

국내외 창업 교육 및 창업 현장에 있어 창업자 개인이 아닌 팀 단위의 역량을 중요시하고 있다. 다양한 창업지원 사업에서 팀의 구성에 따라 당락을 결정할 정도로 팀은 창업 초기에 빠르게 나아가기 위한 원동력이자 시너지를 낼 수 있는 중요한 역할을 한다. 또한 창업팀의 활동을 통해 구성원들의 역량이 성장하고 발전할 수 있다고 믿기 때문에 실패를 용인하고 재도전할 기회를 주는 등 사회 분위기도 개선되고 있다. 이러한 시대적 변화에 따라 기존의 창업가(entrepreneur) 중심에서 창업팀(entrepreneurial team) 단위의 연구로 흐름이 변화하고 있으나 이에 대한 연구는 매우 부족한 실정이다. 더욱이 국내 연구에 있어 창업팀에 대한 연구는 초기 단계로 해외의 연구 결과에 의존하고 있어 한국의 창업환경에 맞는 창업팀의 연구가 필요하다. 이러한 연구의 부족은 창업팀이라는 연구 대상이 한정되어있다는 점, 시간의 부족을 겪고 있는 창업 팀원들에게 의미 있는 자료를 끌어내기 어려운 점 등도 애로사항으로 작용하고 있다. 이에 본 연구에서는 창업팀의 특성 중 학습 행동을 유발하는 요인을 찾기 위해 창업팀의 지각된 다양성과 그 다양성을 수용하는 태도에 관하여 연구를 진행하였다. 본 연구의 결과는 다음과 같다. 첫째, 팀원들의 지각된 사회범주 다양성과 지각된 정보다양성이 높을수록 다양성을 수용하고자 하는 의지가 높게 나타났다. 둘째, 정보 다양성과 가치 다양성을 수용하는 태도가 좋을수록 자발적인 학습 행동이 더 많이 발생했다. 셋째, 단순히 다양한 사람들을 섞어 팀을 구성하는 것 자체로만은 학습 행동을 유발하지 않음을 확인하였다. 지각된 사회범주다양성은 정보다양성의 수용태도를 매개로 자발적인 학습 행동에 영향을 미쳤으며, 지각된 정보다양성은 정보다양성과 가치다양성 수용태도를 매개로 학습행동에 유의미한 영향을 주었다. 팀은 긍정적인 영향과 함께 부정적인 영향을 주기도하여 구성원간의 갈등을 야기시키며 창업실패의 요인이 되기도 한다. 본연구는 이러한 팀의 특성을 살펴봄으로서 향 후 창업팀의 육성과 지원 시 팀의 구성원간의 문제에 대한 관심을 유도하고 팀의 특성과 관련한 연구의 확산에 기여할 것으로 보인다.

The aim of this study was to describe how a teacher used technologies to improve underserved student's learning in a low-resourced rural elementary classroom and provide implications for teachers' use of technology. The in-depth case study was conducted in a one-student classroom setting that isolated the fifth grader from social and collaborative learning opportunities. The qualitative data was collected in forms of classroom observation field notes, teacher interviews, student interviews and student's reflection journals. Findings are as follows: First, technology partakes an import role in a one-student classroom to support student's collaborative learning. Second, to overcome a digital divide, the teacher created a technology-enhanced environment with alternative methods of her own and supplemented teacher-created resources. Third, the teacher used technologies to support adaptive instruction based on student's needs.

For an effective listening to music, a repeated listening to music should be possible without any restriction of time and space as well as to music for a music class and the various multi-media learning materials for listening to music is required. However, an individualized and repeated listening is difficult and an individualized listening materials are lacking. To solve these problems, learning system for listening to music in elementary school sharing learning materials required for it and including learning factors of listening to music is required. Therefore, this study analyzes learning factors of listening to music in elementary school and the learning system for listening to music is designed and developed to make elementary students have their own active listening to music and feel achievement and confidence by teacher's evaluation of their writings after listening to music and experience a joyful musical activity. And it is applied to elementary school.

There has been increasing demand of hypermedia as computing and educational environment change. Most authoring tools developed recently have various built-in functions., but they are not enough to create hypermedia program or easy to learn. Even though teachers might try to develop hypermedia program with existing authoring tools, they usually come to face with the difficulties of creating new nodes, adding new data, or keeping user's activity records. Therefore, this study investigated to present a prototype of Educational Hypermedia Editor that can be conveniently used in hypermedia programs. According to the theories of courseware design, instructional design, learning theory, and hypertext and hyperemia, design strategies for the study were selected. Based on the analysis of the characteristics of domestic authoring tools as well as foreign authoring tools, the Educational Hypermedia Editor that has authoring and executing mode was designed and developed. Because the Educational Hypermedia Editor was designed for information retrieval CAI(Computer Assisted Instruction) materials, it is expected that the Educational Hypermedia Editor will be extensively used in the urea of social science classes, investigation studies, and information processing studies.

Chemical batteries are indispensable materials, and technologies related to chemical batteries are important as they are linked to various social problems; further, they directly affect our lives. Thus, the topic of chemical batteries is suitable for industrial education. However, there has not been sufficient educational use of chemical batteries in Korea, and existing research materials do not correspond with the present curriculum. The STS teaching-learning materials about chemical batteries in this study were developed by the curriculum development model (preparation, development, improvement) for chemical engineering students in specialized vocational high schools. In the preparation stage, the study topic and the learning objective were selected by analyzing previous research about the STS and chemical battery. At the development stage, STS class plan and teaching-learning materials were developed. In the improvement stage, The STS curriculum plan and the teaching-learning materials were verified by a group of specialists and a survey regarding student satisfaction was conducted. As a result of conducting the class with the teaching-learning materials developed in this study, a positive effect in terms of students' perceptions, understanding and interest.
