The purpose of this study is to analyze how a mathematics teacher and a high school student make the meaning in a graph and how aspects of the interpretation of a graph are interacted during the signification process, and to suggest considerations for teaching and learning of a graph. The findings of a case study have led to conclusions as follows: All of them have a difficulty in making the meaning in a graph and construct the meaning as a nested signification model. In the process which they make the meaning, they interrelate cognitive, contextual, and affective aspects and construct interpretants. In this process, a teacher focuses on cognitive aspect, based on a qualitative approach. But a student considers contextual aspect more, based on a quantitative approach. This study suggests three considerations for teaching and learning of a graph.

In this study, we investigated the characteristics of planning lessons using analogies by pre-service science teachers. Eight pre-service teachers at a college of education in Seoul participated in this study. After the workshop of instructional analogies in science education, they planned lessons using analogies. We also conducted semi-structured interviews. For the analyses, we used a revised framework from a previous work which characterized the dimensions of teaching through analogies. The analyses of the results revealed that most pre-service teachers planned to use analogies in beginning or developing lesson and to present analogs before target concepts. The degree of activity allowed for students was not high. Many did not recognize the necessity of assessment and did not include assessment in planning lessons. They planned clarified mapping strategies which are teacher-centered and also not to cover unshared attributes and multiple analogies, because they thought that students could misunderstand mapping and unshared attributes could make students confused. Most planned to use figures, pictures, and videos to help students understand analogies that they presented. Educational implications of these findings are discussed.

During the period of rapid industrial growth, specialized high schools were important vocational education institutions trained specialists and technicians. But now, specialized high schools turned into high schools where the low-ranking students who were pushed out of the competition for admission due to a decline in the education population, changes mostly in labor demand in the labor market, and discrimination against skilled workers. In order to solve this problem, the middle school 3rd grade teachers in charge of the middle school can provide early career guidance, so that they can decide to go to the specialized high school according to their aptitude and talent rather than their grades. The purpose of this study is to investigate the relationship between general characteristics and perception of middle school 3rd grade teachers, and the rate of decision to enter specialized high school. In 2018, The middle school 3rd grade teachers in charge in Daejeon metropolitan city were selected. The results of this study were as follows: When 3rd grade teachers in charge are the male teachers 21.01%(M=.2101) of their students go to specialized high schools. When they are teachers who have not graduated from college of education(M=.2110), with doctoral degree(M=0.3064), of their students go to specialized hight schools. Finally, there was a significant positive relationship between perceptions of high school teachers (β1 = .245, p = .000) and high school graduates (β2 = .149, p = .027). The regression equation derived from this is y = -0.56 + 0.037 * β1 + 0.025 * β2 10.1% (R² = 0.101).

The purpose of this study is to develop a 'Healthy Couple Relationship' curriculum(plan) for high school home economics based on backward design. In this study, the content elements of 'Healthy Couple Relationship' were extracted through literature analysis, and the need for contents of 'Healthy Couple Relationship' was surveyed in 197 families of home economics teachers and 154 high school students. Based on this, the 'Healthy Couple Relationship' curriculum(plan) of high school home economics curriculum was developed as the backward design, and it was verified by the expert group. The results are as follows: First, when measured on a 5-point Likert scale, the mean scores of the need for content elements of 'Healthy Couple Relationship' was 4.39 for teachers, and 4.02 for students, respectively. The content elements of 'understanding dating violence' was 4.70 for teachers and 4.19 for students. Second, the developed 'Healthy Couple Relationship' curriculum consists of two templates, one for each unit, including curriculum goals, unit composition and unit goals, 8 learning subjects and content elements, evaluation plans including 24 lesson plans. In this study, it is meaningful to propose a "Healthy Couple Relationship" curriculum as an elective course in high school home economics curriculum in preparation for the high school credit system, and to lay the foundations for opening elective courses.

This study focuses on the application of the data mining technique logistic regression analysis and decision tree analysis to the domestic public database called Korean Children Youth Panel Survey (KCYPS) to derive a series of important factors affecting the enhancement of life satisfaction of domestic youth. As a result, the general impact factors on life satisfaction for each grade were derived from logistic regression. Using decision tree analysis, we came to conclusions that those factors such as depression, overall grade satisfaction, household economic level, and school adaptation play crucial roles in affecting high school adolesscents' life satisfaction.

There are many studies that intrinsic learning motivation and social support play an important role in the study of children and adolescents. However, studies examining the effects of intrinsic learning motivation and social support by measuring the actual academic performance of elementary school students are rare. This study attempted to verify the effect of intrinsic learning motivation on Korean language performance and moderating effect of social support in 5th and 6th graders in elementary school. 122 elementary school students in local county-level areas participated in this study. The Korean language test was conducted about 5 months after intrinsic learning motivation and social support of families and teachers were measured. The results revealed that Korean language performance showed a significant positive correlation with intrinsic learning motivation and social support, and also showed a significant correlation between learning motivation and social support. In the regression analysis with control variables, it was found that intrinsic learning motivation had a significant effect on Korean language performance. The moderating effect of social support was analyzed by dividing it into family support and teacher support. The interaction effect of learning motivation and social support was significant only in teacher support, not in family support. In specific, when teacher support was high, Korean language performance was high regardless of the student's learning motivation level, but when teacher support was low, the student's learning motivation mattered in the performance. Based on the results of this study, implications and limitations were discussed.

Together with the development of ubiquitous computing technology and robot technology, intelligent type robots are being utilized in many areas and the range is expected to become wider and wider. Among many service robots, the educational robots are being diversely studied in the field with the concept of r-Learning. Presently, teaching assistant robots require a lot of HRI studies prior to their practical use in the very near future and are not sufficient yet. Especially, the reactions of students based of the styles of robots (e.g. serious robot, playful robot) are very important in producing robot contents but there has been no case study on them. Therefore, in this study, the appearance of the IROBI was changed to become a teaching assistant robot and was used to test and compare elementary school students' interest, achievement and concentration depending on the styles of robot (playful, serious). The results showed that the interest was high in the group that had studied with the playful robot. The achievement however, did not show significant relations with the style of robot and that the concentration was high in the group that had studied with the serious robot.

The purpose of this study is to scrutinize the characteristics of a teacher's discursive competence on the basis of mathematical competencies. For this purpose, we observed all semester-long classes of a middle school teacher, who changed her own teaching methods for the last 20 years, collected video clips on them, and analyzed classroom discourse. Data analysis shows that in problem solving competency, she helped students focus on mathematically important components for problem understanding, and in reasoning competency, there was a discursive competence which articulated thinking processes for understanding the needs of mathematical justification. And in creativity and confluence competency, there was a discursive competence which developed class discussions by sharing peers' problem solving methods and encouraging students to apply alternative problem solving methods, whereas in communication competency, there was a discursive competency which explored mathematical relationships through the need for multiple mathematical representations and discussions about their differences. These results can provide concrete directions to developing curricula for future teacher education by suggesting ideas about how to combine practices with PCK needed for mathematics teaching.

최근 교사들의 잇단 극단적 선택으로 학교의 변화와 상황에 대한 문제의식이 사회적으로 날로 높아지고 있다. 교직에 대한 선호도가 급격히 떨어지고 교직 이직 비율도 빠르게 높아지고 있어 교육의 질을 걱정하기에 이르렀다. 드러난 문제가 원인의 하나일 수 있으나 많은 연구에서 교사들의 직무스트레스가 심각한 수준임을 밝히고 있고, 학교교육 현장에는 교사들이 조직에 몰입하기 어려운 다양한 문제들이 있음을 밝히고 있다. 그럼에도 교육현장에서는 학생, 교사들이 함께 성장할 수 있고 모두가 만족하는 교육 활동을 실현시키고 변화와 혁신을 통해 교육역량을 높이고자 지속적으로 노력하고 있다. 본 연구는 초등학교 교사의 직무스트레스와 감정 노동이 조직몰입에 미치는 영향을 조사 분석하고 두 변인 즉 직무스트레스와 감정 노동이 직무몰입에 미치는 영향에서 긍정심리자본의 매개 효과를 알아보는데 그 목적이 있다. 교사 직무스트레스 실태를 종합적으로 파악하고자 관계 요인, 업무요인, 정책 요인으로 나누어 분석(김종민 외, 2018. 경기도교육연구원)하고 특히 스트레스 요인 중 가장 비중 있는 감정 노동 부분은 분리하여 더 상세히 분석하고자 한다. 이를 위해 경기도, 경기도, 서울, 전라남도 소재 초등학교교사 500명을 대상으로 자료를 수집하여 SPSS 20.0 프로그램을 활용하여 변인들의 기술통계치를 산출하고자 한다. 초등교사의 인구통계학적 변인간에 유의한 차이가 있는지 확인하기 위해 t-검정과 일원배치 분산분석(ANOVA)을 실시한다. 그리고 연구에 포함된 변인들간의 상관계수를 산출하고 Baron과 Kenny(1986)의 절차에 따른 3단계 회귀분석과 부트스트래핑(bootstrapping) 기법을 적용하여 매개효과의 유의성을 검증하고자한다.
