In this study, we comprehensively investigated the cases of science teachers who implemented NOS assessments in Science Inquiry Experiment. Two science teachers working at high schools located in Seoul who taught and assessed NOS in Science Inquiry Experiment according to the 2015 revised curriculum participated in the study. We collected lesson and assessment materials and observed NOS lessons and assessments. We also conducted interviews. Based on the collected data, we analyzed the processes of the teachers' NOS assessments. The analyses of the results revealed that the teachers constructed the assessments by themselves due to a lack of NOS assessment experience and related materials. They had difficulties in selecting an appropriate assessment method and constructing assessment questions and criteria. Both teachers found it difficult to assess an understanding of NOS because it concerns the subjective views of individual students. Therefore, they had difficulties in setting detailed assessment criteria, which also led to difficulties in the overall assessment process. There was a difference in the reflective level of the assessments between the two teachers. In the reflective activities of low levels, the assessments were not properly enacted because it was difficult to infer students' understanding. Orientation toward teaching NOS influenced the perceptions of NOS assessment and overall lessons, resulting in a difference in NOS assessments. Finally, the absolute evaluation of Science Inquiry Experiment also affected teachers' NOS assessments. Based on the above results, implications for effective NOS assessments in schools are discussed.

The purpose of this study was to develop a teaching-learning program for the unit 'youth sex and peer relationship' of middle school seventh - grade technology & home economics by applying Keller's ARCS model in five stages: analysis, design, development, implementation and evaluation. In the analysis stage, earlier studies of motivation were analyzed, and a survey was conducted to select ARCS strategies, in the design stage, in which way motivation strategies should be designed, in the development stage, a teaching-learning program for eight sessions was developed in accordance with the two practical problems. In the implementation stage, middle school seventh graders took six sessions according to the program, in the evaluation stage, the highly applicable teaching-learning program was finalized in response to the needs of the students. This study focused on revising ARCS strategies which provide in the teaching-learning programs by implementing and evaluating. Students desired for interesting instruction. It was necessary to develop new ARCS strategies can apply to Home Economics.

The purpose of this study was to explore middle school students' perceptions about earth systems in order to implement the 2009 revised national science curriculum effectively. A total of 1219 students participated in the survey and asked to determine their basic understandings about earth systems, self-reported knowledge level, and perceived significance level of the 23 earth systems concepts (contents). In relation to students' basic understandings about earth system, approximately 67% students reported that they didn't know about the term of the earth system. Atmosphere and hydrosphere were highly perceived as major component of earth system. However, cryoshere was perceived to be least familiar by the subjects. The findings also showed that students' self-reported knowledge level and significance level about major ESU#4, #5, #6 related concepts (contents) were significantly different by gender. Most of male students were more knowledgeable and perceived more significant than female students. Regarding the difference of the perceived significance level by grade, 10 out of 23 concepts were significantly different. Some implications for implementing the revised curriculum and school fields were discussed.

우리나라에서 공과 대학 학생들의 효율적인 교육을 위하여 유사학과의 계열별 통폐합이 추진되고 있는 바, 현 시점에서 미국에서 논란되어지고 있는 전기공학 교육과정의 내표하고 있는 많은 문제점이 미국 뿐만 아니라 한국에서도 공통적인 문제점들임을 감안할 때 미국의 여러 기관, 학교 등에서 연구, 계획, 실행되어가고 있는 교과과정에 대해 그 방향을 정리 검토하여 한국의 전기공학 교육발전에 참고하려 한다. 미국 대학에서 일반적으로 시행되고 있는 교과과정 및 제도는 한국과 거의 유사하다고 볼 수 있다. 그러므로 일상적인 제도에 관한 것을 포함시키지 않고 현재의 공통적인 문제점들을 개선하고자 하는 새롭고 창의 적인 개혁 방안들을 중심으로 정리하였다. 이 글에서는 한국 사회의 현실성이란 변수를 감안하지 않고 미국의 전기공학교육의 방향을 객관적으로 검토하는데 촛점을 두었다.

In this study, we carried out mathematics teacher-training course. The topic of this training course is the understanding of content area reading in school mathematics. The teacher-training course is planned to guide mathematics teachers can perform effectively the teaching of content area reading. In particular, we illustrated the pre-service mathematics teacher education practice. Mathematics teachers investigated various teaching strategies that can lead their students read reading materials related to mathematics effectively. In this training courses, teachers reflects on their own experience and they have an opportunity to learn the new strategies that improve their teaching methods. Teacher educator and in-service teachers share and discuss their practices, they have a meaningful learning experiences. In this study, we presented the processes of the teacher-training course and the results of practice. Furthermore, on the basis of the limitations of this study, we suggested recommendations for the future teacher training program.

In this study, we conducted mathematics teacher training courses for an applying of 'Socratic method' in school mathematics. Teacher training courses were conducted with a total of 3 hours for 68 secondary mathematics teachers. In these courses, we overviewed the characteristics of Socratic method. Moreover we examined the mathematics lessons by Socratic method. And we dealt with the educational examples of Socratic method identified in previous studies. In addition, the survey was conducted before and after the teacher training courses. Through the survey, teachers have an opportunity to check their knowledge on Socratic method and reflect on their mathematics class. Based on the survey response data, we analyzed mathematics teachers' knowledge on Socratic method and the changes in teachers' thinking on their mathematics class. Based on the findings of this study, we proposed three directions of teacher education.

It seems likely that the characteristics of future society will include an emphasis on diverse and expansive data sets and the use of AI technology. Because of this, school leaders within the traditional, textbook based educational framework there will be changes should meet the 2015 Revised National Curriculum and prepare students for future societies. The purpose of this research paper was to suggest the nature of and policies necessary for better educational processes in middle and high schools after they've been improved in accordance with the 2015 Revised National Curriculum. This paper implemented its survey and interview of school principals through the guidelines provided by UNESCO Bangkok's transversal competence research. Analysis results and research participants were practicing strengthened education in the course of their daily activities. The educators involved received positive evaluation from their students. Further, pedagogical opinions were suggested regarding the effects of school principals on various strengthened education elements. This paper's suggestions within the context of the 2015 Revised National Curriculum are expected to continue reinforcing the overall positive effect of the currently in practice strengthened education methods. Furthermore, it can contribute to the development of the next National Curriculum with empricial data.

인터넷의 발달로, 사이버 환경을 위한 C 프로그래밍 교육 컨텐츠가 많이 개발되고 있으나 적절한 실습 환경까지 제공되지 않고 있다. 그러나 프로그래밍 언어의 교육은 실습이 수반되지 않으면 그 효과가 상당히 떨어진다. 본 논문에서는 인터넷상에서 효과적으로 사용할 수 있는 C 프로그래밍의 실습환경을 구축한다. 특히, 학생들이 이해하기 어려운 함수 프로그램의 실행과정을 Java Applet을 사용하여 시각화 보여준다. 함수 프로그램 실행 시각화기가 설계되고, Java 환경에서 구현된다.
