The 7th national curriculum requires the paradigmatic shift in education from teacher-centered to student-centered instruction. But, teachers beliefs on instruction have not been changed during implementing of the mathematics textbooks based on the curriculum. More exactly speaking, they are changed very slowly. Therefore, some beliefs they should establish in order for them to implement it were discussed: Perspectives of students' intelligent ability, learning goal for the every lesson, the passibility of teaching contents involved in the national curriculum, the size of classroom, and students' achievements.

지금의 수학교육현장은 결과적인 완성된 지식을 교사 주도하에 연역적으로 지도하는 것에 대해 문제가 있는 것으로 지적되어 그에 대한 대안으로 본 논문은 인지갈등을 통한 수학과 학습 모형을 이용한 교수-학습 방법을 제시하고자 한다. 인지 갈등을 유발하여 학습동기를 부여한 후 학생과 교사가 함께 그 갈등을 풀어 나감으로서 동기유발과 수학적 능력을 길러 줄 수 있을 것이다. 특히, 보편화된 컴퓨터 환경은 이러한 수업을 더욱 용이하게 함에 주목하고 또 문제 설정 등 다양한 기법을 통한 수업 모형을 효과적으로 활용할 수 있으며 주제에 따라서는 수학사적 내용을 첨가하여 흥미 있는 수업을 할 수 있다. 이러한 수업방법은 학생들의 흥미와 참여를 유도하게 되어 효과적일 것이다.

The purpose of this study was to investigate the perceptions and practices of secondary science teachers who participated in an Earth science teachers' research roup about teaching geologic field trips. Four Earth science teachers participated in this study. Data included field trip observations, semi-structured interviews with teachers and students, and analysis of instructional materials and students' reports from the field trip. Field trip observations and interviews were video- and audio-taped and transcribed. Results indicated that teacher participants focused more on aesthetic objectives for geologic field trip. The participants' instruction tended to show rather teacher-centered explanation due to limited time at each field site though various teaching strategies were used at times to engage students in a scientific inquiry. This group of teachers strived to develop their professional ability to guide geologic field trip by working with a small study group with colleagues, participating geologic field trips, and enrolling graduate programs.

The purpose of this study was to compare the composition of the government guidelines for the educational curriculum of Japan announced in 2016 with the outline of the 2015 revised educational curriculum of Korea. To compare the composition of the national level curricula of the two countries, the composition systems and content details were analyzed along with the trends of emphasis placed on informatics education. The analysis indicated that as for the Japanese government's guidelines, it was suggested that the causes of revisions, and purposes and methods of fulfilling goals be added, and thus the appropriateness of the guidelines was emphasized. As for Korea's revised curriculum, a gap caused by segmental development of the outline and details of the curriculum were found in addition to errors in curricular composition and direction setting which were carried out without consideration to the transition time required or changes of subjects. To ensure sufficiency of the curricular contents and education reflecting the situations of each time phase, the necessity to improve the overall curricular framework was suggested. This study holds significance as it provides the introspective insight that the goals and directions of education cannot be set properly when the curricular framework is established without recognition of the contents.

The purpose of this study was to analyze the structural relationships between adult educators' instructional leadership, learners' motivation and performance among those participants in education for urban-rural migration. The survey was conducted among 22 agricultural educational institutions in South Korea, and a total number of 1,109 learners responded to a questionnaire. In order to verify the hypothesized research model, the collected data were analyzed with structural equation modeling. The major findings of this study were as follows. First, adult educators' instructional leadership had a direct effect and an indirect effect on learners' performance. Second, adult educators' instructional leadership had a direct effect on learners' motivation. Third, learners' motivation had a direct effect on learners' performance.

소셜미디어를 통한 여론분석과 브랜드 모니터링에 대한 요구가 증가하면서, 빅데이터로부터 감성을 분석하는 기술에 대한 필요가 늘고 있다. 이를 위해, 본 논문에서는 단순 긍/부정 감성이 아닌 20종류의 세분화된 감성을 분석하기 위한 감성어휘 구축 알고리즘을 제시한다. 감성어휘 구축을 위해서는 준지도학습을 사용하였으며, 도메인에 특화되지 않은 일반 감성어휘를 구축하도록 학습되었다. 학습된 감성어휘를 인물, 스마트기기, 정책 등 다양한 도메인의 트위터 데이터에 적용하여 세부감성을 분석한 결과, 알고리즘의 특성상 재현율이 낮다는 한계를 가지고 있었으나, 대부분의 감성에 대해 높은 정확도를 지닌 감성어휘를 구축할 수 있었고, 감성을 직간접적으로 나타내는 표현들을 학습할 수 있었다.

The aim of this study is to develop and suggest a reading strategy to learn for integrating reading and writing. The reading and writing strategy could be divided in directed strategies related to the cognitive process and indirected strategies to carry out the process successfully. Therefore, its strategies are constructed of the indirected strategy corresponding with the instructional design model and the direct strategy containing specific action plans of the model's progressive stages. When considering the reading to learn could be run as a program in the school, in this study, the basic model of the indirected strategy is devised with four steps of 'preparing-designing-implementing-evaluating'. And the implementing stage of the read to learn combining reading and writing is consisted of six steps as 'selecting subjects-considering contents-searching-writing-correcting-publishing'. Also, proper indirected strategies such as graphic organization and checklists are suggested in order to assist reading and writing activities in the implementing stage.

오늘날 우리의 교육은 교육과정에 나와 있는 내용의 구성에 대해서는 어떤 부분을 강조해야 하는가? 그리고 왜 강조해야 하는가?에 대해서 학생들에게 잘 전달하지 않은 채, 어려운 공식 ${\cdot}$ 원리 ${\cdot}$ 법칙 등의 유도와 문제풀이 등으로 인해 학생들은 점점 수학에 대해 흥미를 잃고 있다. 본 연구에서는 현행 고등학교 수학에서의 미분과 적분 단원의 내용 구성에 있어서 문제점을 살펴보고, 수학 학습이 학습자에게 좀더 의미 있는 활동이 되도록 미분과 적분 단원의 내용에 대한 바람직한 지도계열에 대해서 살펴보고, 지도시 특히 강조해야 할 점들을 대학수학에서의 이론적 배경을 토대로 살펴본다.
