In this research, there was an investigation about the objective and content domains concerning marine education in the Fish and Marine High School. Also, validity and guidance level on the classification were analyzed. According to the analysis, analyzing guidance level of Marine related contents which are included in school marine education is as follows. There are 971 information and knowledge domains, 710 skill domains, 5 value and attitude domains and 8 behavior and participation domains in the objective domain in school marine education. The number of the knowledge domains was most while attitude domains was least. Content domain of school marine education consists of 774 ocean human and marine ecology domains, 461 artificial marine environment and facility domains, 290 marine resource domains, 76 marine pollution domains, 123 marine conservation and measure domains. So, ocean human and marine ecology domains were most while ethics of marine conservation domains were not included.

Textbooks are important resources in support of teaching and learning mathematics competencies which are emphasized in the most recently revised mathematics curriculum. This study analyzed how six mathematics competencies and their sub-elements are implemented in the mathematics textbooks for the fifth and sixth grades. A total of 465 activities or items in the targeted textbooks were analyzed. The findings of this study showed that both the communication competence and the reasoning competence were the most frequent competencies, followed by the problem solving competence. In contrast, the other three competences (i.e., creativity and integration, attitude and practice, and information processing) were less popular. Detailed analyses of sub-elements according to each competence revealed that one or two specific sub-elements were emphasized within a competence. Whereas "expressing one's idea" was the most prevalent sub-element in the communication competence, both "analyzing mathematical facts" and "observation and conjecture" were the most frequent in the reasoning practice. Specific sub-elements were jointly implemented within or across competences. "External connections of mathematics and integration" in the creativity and integration competence was carried out in relation to "recognition of values" in the attitude and practice competence. This paper also included some examples of activities or items showing how specific sub-elements of each competence were reflected on. This study is expected to provide implications on how to implement mathematics competencies throughout the textbooks.

학습자는 교수 학습 상황에서 대부분 배운 내용을 잉킹을 통해 정리한다. 교수자와 학습자 사이에서 잉킹을 통한 상호작용은 매우 중요하며 이와 관련된 다양한 연구가 진행되고 있다. 디지털교과서가 점점 보급되고 있는 상황에서 서책형교과서와 디지털교과서가 공존하는 현재의 과도기적인 교육환경은 일반적인 잉킹과 디지털 잉킹이 공유하고 있다. 이에 디지털 교과서를 활용한 협력적인 학습상황에서 과제를 제시한 후, 일반적인 잉킹과 디지털 잉킹을 학생들에게 그룹별로 각각 적용하도록 환경을 구성하였다. 본 논문에서는 일반적인 잉킹환경과 디지털 잉킹환경이라는 두가지 잉킹 방식을 적용한 후에 학생의 태도 및 판단, 문제 해결의 정확성, 학생의 선호도에 어떤 영향을 미치는지 분석하였다.

This research is aimed to analyze the causes of junior high school students' problems that was showed in a poor way at learning mathematics. So this is for the purpose of providing the basic data for searching for a means of teaching-learning to understand stagnant students. 5 male junior high students in teaming-stagnation were targets of this research, and we used two kinds of questionnaire in the field to find out the causes of learning-stagnation. We searched these students for the causes from a different standpoint of learning habits and self-possessed manners in mathematics.

지구과학 분야에서 가장 어렵게 느껴지는 내용인 천문분야는 다른 과학 분야와 달리 탐구 대상이 천체들이 먼거리에 있고, 쉽게 관측하기 어려우며, 실험실에서 동일실험과 반복 실험이 불가능하여, 추상적이고 직접 관측하기 어려운 개념에 관한 연구들이 많다. 따라서 이 연구에서는 레이저 커팅기를 사용해 지구과학교과 중 별자리를 구성하는 별들의 상대적 거리를 수학적으로 계산하는 과정과 고등학교 물리교과 중 LED 광원의 원리를 알고 LED 모듈을 제작하여 최종적으로 아름답고 과학적으로 가치가 있는 입체 별자리 교구를 제작하는 형태의 STEAM 교육 프로그램을 개발하고 시범학교 적용을 하였다. 이에 지능정보화 사회에 발맞춰 천문학 지식을 창의 교육의 형태로 교육하는 새로운 교육법을 실현한 연구결과들을 발표하고자 한다. 또한 개발한 프로그램의 효과성을 검증하기 위해 STEAM 관련 태도 검사와 논리적 사고력 검사 및 만족도 검사를 실시하였다. 연구결과 개발된 프로그램이 STEAM 태도 검사와 논리적 사고력에 효과가 있는 것으로 나타났으며, 천문수업에 대한 학생들의 인식은 긍정적이었다. 따라서 후속 연구에서는 다양한 학년 및 위계에 맞는 프로그램의 개발과 다양한 지역 등의 현장 적용을 통한 연구가 진행되어야 할 것으로 판단된다.

This paper describes an in-depth study on the effect of students' writing of a reflection journal on academic achievement in Linux courses. For this purpose, students who took a Linux class were surveyed. Those participants were divided into two groups; an experimental group and a control group. Their academic achievement was compared and analyzed for this study and reflection journal was applied for 6 weeks after middle test. The results suggests that task achievement, expectation, learning persistence, self-efficacy, learning attitude, satisfaction in writing a reflection journal, and subject study were improved for the students who wrote a reflection journal. In addition to this, it suggests that the writing of a reflection journal has a significant effect on academic achievement in Linux subjects. It is meaningful for teaching skill of computer engineering education.

This study analyzes how statistical literacy is implemented along with the statistical problem-solving process as described in the Statistical Estimation Unit of the textbook by the 2015 revised mathematics curriculum. The analytical framework was developed from the literature, and consists of 'context', 'variability', 'mathematical and statistical knowledge', 'using of technological instruments', 'critical attitude', and 'communication'. From the perspective of the statistical problem-solving process, the analysis revealed that many tasks equivalent to 'Analyzing Data' but lacked tasks related to 'Interpreting Results' and 'Formulating Questions'. As a result of analyzing the reflection of each element of statistical literacy, 'mathematical and statistical knowledge' was the most common task, but 'critical attitude' and 'using of technological instruments' were rarely dealt with. Based on the results of this textbook analysis, it was intended to provide implications for improving the curriculum and the development of textbooks for the growth of statistical literacy.

In this study, we develop the mathematical modeling teaching materials focused function units of mathematics textbooks and establish the appropriate teaching and learning model. Using mathematical modeling materials and developed instructional materials for teaching high school students is aimed to improve the academic achievement, mathematical attitude and fear. The problem of this study is as follows : First, between the groups using mathematical modeling and a traditional textbook teaching academic achievement groups showed that there is a difference? Second, between the groups using mathematical modeling and a traditional textbook teaching mathematics between groups showed that there is a difference of mathematical attitude and fear? Third, what are the lessons for the students' responses using mathematical modeling?

This study evaluated middle school teachers' perceptions and demands for changing in Food and Nutrition sections of Home Economics and also identified variables related. Teachers expressed unfavorable attitudes to the usefulness of contents in real life, and clearly perceived the importance of a basic theory of nutrition in general and adolescency among 12 items related with Food and Nutrition section. Most of the teachers pointed the way in which textbooks are described and organized were heavily oriented into lectures, more than creative discussion and diverse activities. The insufficient materials for teaching-learning were also pointed as barriers in improving the level of quality of Food and Nutrition sections in middle school Home Economics textbooks. Teachers had strong beliefs that textbooks, based on 7th National Curriculum, should be changed and improved not only in contents but also in organizations. Cognition of teachers on the appropriateness, in terms of quantity of contents, competitiveness for developing students' capacity. level of quality, and interests among students and teachers, was consistent and independent indicator of their needs for changing. These results suggest that the next textbook should include more materials for teaching-learning designed to expand students' capacities and develop critical thinking skills. Effective educational curriculum should integrate sufficient activities together with detailed instructions. Creative activities may allow students to learn and connect these activities to the contents in Food and Nutrition section of Home Economics curriculum.
