이 연구의 목적은 자기주도 초등교재의 조망인지기제 활용이 학업성취도 향상에 미치는 효과에 대해 살펴보고 학업성취도 향상에 영향을 주는 조망인지 하위 구성요소(계획, 점검, 평가)가 무엇인지 알아보고자 하는 데 있다. 연구목적을 달성하기 위해 실험집단(조망인지기제 활용 학습교재사용 집단)과 통제집단(기존 교재사용 집단)으로 구성된 초등학생 55명을 대상으로 실험을 실시하였다. 분석결과 첫째, 자기주도 초등교재의 조망인지기제 활용집단(M=70.38)과 전통식 학습집단 (M=60.84)의 학업성취도 평균은 통계적으로 유의미한 차이를 보였다. 둘째, 조망인지 하위 구성요소 중 '점검' 요소가 학업성취도 향상에 긍정적인 영향을 미치는 것으로 밝혀졌다.

In order to measure students' fun and the effectiveness of teaching materials related to computer science theory, this paper conducted an experiment lesson against middle school students using Timbel's 'Unplugged' textbook. A preliminary test was conducted and it revealed that the students' understanding of computer science theory was extremely poor. The learner's fun for the experimental lesson showed the positive reaction in the viewpoint of expectation, engagement, endurability. In post-test after one month, the students were able to recall most of the materials covered during the experiment lesson. In addition, they all showed sign of good understanding. In conclusion, Timbel's textbook proved effective in increasing students' fun and learning ability related to computer science theory. Furthermore, this paper would like to suggest a new type of Informatics science teaching material that might be essential for future computer science education.

Now, most of programs developed were presented as form of item pool by dividing problems by section and level for the level differentiated course, so the utilization is decreasing at the field caused by unconsidered school underachievement elements by achievement. Especially, the study on teaching materials and effective measures map for mid-low level students with low utilization is more urgent. Therefore, in this study we will promote teaching method for improving learning achievement at high school. The development teaching materials(the performance evaluation and diagnostic assessment, reconstruction of textbooks) will be applied to classes for the underachieving students directly, and the achievement in the experimental class was significantly improved compared to the comparative class and the meaningful conclusions could be drawn as results of conducting same assessment based on the experimental class and the comparative class.

본 논문에서는 로봇 매니퓰레이터의 순방향 기구학 학습에 있어서 로봇의 비용적인 측면으로 인하여 실재 로봇 매니퓰레이터를 교보재로 사용하여 실습을 하기에 제한되는 환경과 교재만으로 학습하는 제한된 환경에서 학생들이 이해하는 것 뿐만 아니라 검증이나 실험을 하기가 어려운 점을 개선하기 위해서 증강현실 기반의 시뮬레이터를 제안한다 로봇 기구학에서는 주로 교재를 사용하는데 실재로 존재하는 모델보다 회전 관절(revolute joint)과 병진 관절(prismatic joint) 모형의 조합으로 모델링한다 관절의 모형을 일종의 증강현실의 마커로 사용하여 교재에서 제안하는 모델에 더해서 개인이 조합한 모델 또한 실습이 가능하도록 하는 증강현실 시뮬레이터를 제안한다.

The purpose of this study is to analyze the perception and need of the early childhood education field on authentication of teaching materials and implements for young children. To achieve this, a survey was carried out on 350 teachers and directors in Daejeon-based kindergartens and child-care centers from September 21 to September 30, 2013. The results of the analysis are as follows. First, 59.4% of them thought that it needed the evaluation authentication of teaching materials and implements for young children. 32.9% of them had a high perception of the early childhood education field. 39.4% of them had high need of the early childhood education field. And 45.1% of them expected a high effect of introducing the evaluation authentication system of teaching materials and implements for young children. Second, most of them had the highest need of the evaluation authentication of teaching materials and implements for young children in terms of education, followed by function and field. And most of them placed the highest emphasis on social development, safety and language in terms of education, function and field, respectively. Consequently, the use of teaching materials and implements, which the social development and safety in terms of education and function are respectively evaluated and authenticated by the diversity of teaching materials and implements for young children, has need of the high evaluation and authentication of teaching materials and implements that can guarantee the quality when young children use a lot of experiment and observation implements such as block play, reading materials, manipulating materials, making implements.

In order to promote national competition on knowledge based-society in 21centuries, it is important for us to train talented people who have much creativity. Comparing curriculums and contents studied in SECG (Science Education Center for the Gifted) and other organizations is object of this thesis. Finding implications of proper GATE(gifted and talented education) by understanding the present conditions is also a part of this thesis. We select 5 Science Education Centers for the Gifted and devise framework for analysis in order to analyze chemical textbooks in GATE programs. The framework consists of 6 categories including the contents, the level of activities, the opening extent of experiments, and the ability to think creatively. In our study of textbooks, we have found that the contents of chapters are divided properly but lacked the field of frontier and convergence science. Their activity types will have to develop programs which consist of various activities such as lectures and experiments. Precedent studies and study activities to promote scientific thinking were rated highly in general ratio. The level of studies that we analyzed lacked creative activities very much. In the opening extent of experiments, activities in the level 2 and the level 3 were low-rate. And in our study of thinking creatively, activities of promotion for expanded and related-ability to think seemed to lack. In order to achieve specific education for the gifted children, developments of GATE program is required. In the in-depth analysis from the questionnaires of Likert's method's descriptions, narrations, and interviews, it is divided into two answers in depth: contents of program, management of program. These also divided into two answers by attitude: positive answer or negative answer. According to the responses of the contents of program, the result of analysis shows that most respondents have positive reactions to not only contents and the managing method of SECG programs, but also to individual enhancing-abilities overall.
