본 연구에서는 개념도를 활용한 새로운 수업모형을 개발하고 이를 지구과학 I의 지각변동 단원에 적용하였다. 이를 통해 전통적 수업 방식에 비해 학생들의 학업성취도, 개념도 작성 능력, 개념도 수업에 대한 태도 변화에 어떤 효과가 나타나는지를 분석하였다. 자료는 경기도에 소재하는 한 남자고등학교에서 2학년 학생 128명을 선정하여 실험 처치 후 수집하였다. 그 결과 통계적으로 유의하지는 않았지만 새로운 수업모형은 전통적 수업방식에 비해 학생들의 학업성취도가 향상되었다. 그리고 새로운 수업모형은 전통적 수업방식에 비해 학생들의 개념도 작성 능력과 개념도에 대한 태도에서 유의미하고 긍정적인 차이를 보였다.

우리나라의 2007개정 수학과 교육과정에서는 의사소통 능력의 신장을 수학과 교육 목표의 중요한 부분으로 설정하고 있다. 수학적 의사소통은 학생들이 자신의 사고 과정을 재정립하고, 다른 사람과 상호작용하면서 지식을 구성해 나가는데 중요한 수단이 된다. 이 논문에서는 수학 교실에서 수학적 의사소통 능력을 신장시키기 위한 방안으로 수학적 의사소통 모형을 개발하고, 개발된 의사소통 모형에 따른 수업과 전통적인 교사 중심의 설명식 수업에서 지식의 형성 과정을 비교 분석하였다. 개발된 교수-학습 모형에 따른 수업에서는 전통적인 교사 중심의 설명식 수업에 비해 자신의 문제 해결 방법을 모둠원들과 의사소통을 통해 상호 비교하고, 자신의 의견을 수정하여 가장 적절한 해결 방법을 찾고 합의하였다. 이런 과정을 통해 학생들은 주관적 지식을 객관적 지식으로 구성해 나갔다.

Background: miRNAs are relatively recently discovered cancer biomarkers which have important implications for cancer early diagnosis, treatment and estimation of prognosis. Here we focussed on expression of mir-196a-5p in gastric cancer tissues and cell lines so as to analyse its significance for clinicopathologic characteristics and generate enriched KEGG pathways clustered by target genes for exploring its potential roles as a biomarker in gastric cancer. Materials and Methods: The expression of mir-196a-5p in poorly, moderate and well differentiated gastric cancer cell lines compared with GES-1 was detected by RT-qPCR, and the expression of mir-196a-5p in gastric cancer tissues comparing with adjacent non cancer tissues of 58 cases were also assessed by RT-qPCR. Subsequently, an analysis of clinical significance of mir-196a-5p in gastric cancer and enriched KEGG pathways was executed based on the miRWalk prediction database combined with bioinformatics tools DAVID 6.7 and Mirfocus 3.0. Results: RT-qPCR showed that mir-196a-5p was up-regulated in 6 poorly and moderate differentiated gastric cancer cell lines SGC-7901, MKN-45, MKN-28, MGC-803, BGC-823, HGC-27 compared with GES-1, but down-regulated in the highly differentiated gastric cancer cell line AGS. Clinical data indicated mir-196a-5p to beup-regulated in gastric cancer tissues (47/58). Overexpression of mir-196a-5p was associated with more extensive degree of lymph node metastasis and clinical stage (P < 0.05; x2 test). Enriched KEGG pathway analyses of predicted and validated targets in miRWalk combined with DAVID 6.7 and Mirfocus 3.0 showed that the targeted genes regulated by mir-196a-5p were involved in malignancy associated biology. Conclusions: Overexpression of mir-196a-5p is associated with lymph node metastasis and clinical stage, and enriched KEGG pathway analyses showed that targeted genes regulated by mir-196a-5p may contribute to tumorgenesis, suggesting roles as an oncogenic miRNA biomarker in gastric cancer.

It is necessary that at any rate we try to decrease underachievers by learning deficiency in mathematics to extreme limits under circumstances that mathematics becomes more requisite daily in the 21st century's informative society. However, the traditional teaching method causes a lot of problems in elevating the needed ability for the newly changing society. Accordingly, for the purpose of letting underachievers by learning deficiency have much interest in mathematics, seek the qualitative elevation, have the feelings of self-confidence and accomplishments, escape from desperation, and also teachers choose the activities of small groups, design teaching plans, apply those to teaching-learning activities and finally verify the effect, this researcher sets up a hypothesis as follows: 1. The teaching method through small groups will be effective for the accomplishments of underachievers in mathematics. 2. Its method will bring out the meaningful change in the emotional areas of mathematics. Therefore, so as to prove the above hypothesis, the results through the theoretical approach and practicing teaming by small groups have turned out to be positive.

Since 'teaching coding' or 'programming' classes for computational thinking (CT) education in K-12 are renowned around the world, a pre-service teachers' readiness for integrating CT into their teaching subjects is important due to the fact that CT is considered to be another 'R' from algoRitm for 21st century literacy, in addition to the traditional 3R (Reading, Writhing, and Arithmetic) [2] and CT roles to other disciplines. With this rationale, we designed a guided instruction based CT course for pre-service teachers. We show the effectiveness of the program with respect to the teachers' attitude toward combining CT into their teaching subjects, and mindset changes of learning computing connected with the career development of the teacher themselves. The research focused on the instructional methodology of teaching programing for non-Computer Science Education (CSE) majors who are not familiar with computer science for alleviating the cognitive load of first exposure to programming course under the CT concepts.

The engineering design is very important to make the building of engineering mind in many industry companies because most of companies require commonly the talents for engineering design in order to have originality, reliability and responsibility for university students. But, it can be thought that most of students studying engineering fields in Korea can not have their talents for engineering design in major fields of university sufficiently due to traditional engineering education method. In this paper, a case study of the teaching method for the 'esearch problem' that means capstone design in engineering education is suggested to improve the teaching skills for various engineering based fields. In this paper, a case study of teaching method in research problem for engineering design is shown in order to improve the teaching method for the design in engineering fields.

The aim of this study was to explore teachers' values about teaching mathematics in the classrooms which implemented Lesson Study and Open Approach as a teaching approach. The targeted group was 83 school teachers from 4 schools participating in a teacher professional development project. The data was gathered through teacher questionnaires, lesson observations and interviews. Data analysis is based on Bishop's (1988; 2003; 2007) and Komin's (1990) frameworks. The results from the implementation of Lesson Study and Open Approach in Thai classroom found the different of the roles and behaviors of teachers and students in classroom. The results revealed 3 kinds of values about teaching: Mathematical values, General educational values, Mathematics educational values and also found that most of the teachers valued problem solving as an innovative teaching approach as against traditional approaches they were familiar with.

중학교 생물의 광합성과 호흡단원에 대해 개인별 또는 협동 학습개념도를 적용한 수업결과를 전통적 강의식 수업결과와 비교하였다. 그 결과 개념도를 적용한 학습이 전통적 강의식 수업보다 효과적이었다. 공분산분석을 실시하여 개인별 개념도 작성그룹과 협동 개념도 작성그룹간(p<.008), 협동개념도 작성그룹과 전통적 강의식 학습그룹간(p<.0001)에 유의성있는 결과를 얻었다. 또한 협동개념도작성그룹이 개인별 개념도 작성그룹보다 효과적이었다(p<.04). 따라서 협동개념도 학습방법이 생물학습에 있어 가장 효과적이었다.

The research of combining virtual reality technology with the design elements of children's picture book education is a relatively new topic in virtual reality technology in recent years. Based on the combination of picture book design elements with virtual reality technology and the development of a children's picture book teaching game, this article analyzes the effectiveness of the application of virtual reality technology in children's teaching, and explores the usability of picture book design elements in teaching [1]. Through literature research methods, practical research methods and investigation research methods, this paper lucubrates the application of virtual reality technology in the design elements of children's picture book education so as to provide adequate theoretical and practical support for the research theme. The spatial positioning, vision, sound, and functional requirements of children's picture book games play a leading role in teaching. Practical statistics have proved that it is easier to promote children's mastery of teaching knowledge in a virtual environment. Moreover, use VR's game management function and setting function to solve the boringness of traditional education methods and the limitations of the teaching environment. The feasibility of game operation provides a virtual teaching platform system for children's education, and the teaching effect is remarkable.
