In the context of Korean educational research, the number of qualitative research studies has gradually increased since 2000. It has become one of the most important research methods today. The field of math education is no exception to this trend, and qualitative approaches are now becoming one of the main research methods. This increase in qualitative research has contributed to the provision of detailed information about educational practice, but at the same time, the overall level of credibility in the results of qualitative research seems to be lower than that of quantitative research. This study started with the problem consciousness that the number of qualitative studies is increasing in the field of mathematical education, but there is a lack of discussion on the methodology of applying qualitative research methods. In this study, among the papers published in the journal related to mathematical education, papers using a qualitative approach are analyzed focusing on cross-case analysis. Based on the analysis results, the tendency to use qualitative approaches is diagnosed, ways of improving the validity and trustworthiness of qualitative research results in the field of mathematical education are examined, and implications and suggestions are presented.

The purpose of this paper is to review the trend of research in geographical education since the launching of the Korean Geographical Society in 1945 and to suggest the areas and directions for future oriented research in geographical education. 422 articles (including 12 books) were reviewed and analized for this paper. The outputs of research in geographical education contributed in developing and improving the geographical education in primary and secondary school geography. But to achieve stable and desirable status as a subject in the school curriculum, research in geographical education has to be changed in its target areas and methods. The results and the suggestions of this study are summarized as follows: First, research in geographical education in diverse areas, especially in the areas of significance, aims and objectives, and psychology of geographical education should be preceded the revision of the school curriclum so that the results could be used as the basis information and evidences in decision making about the curriculum. Second, research in geographical education for affective domain and skill development should be implemented more actively in accordance to the trend of integration centering around the dicipline-inquiry skill and citizenship skill. More close relationship between the circles of geographical education and geography would be one of the ways to satisfy the social needs. Third, the linkage between primary and secondary school geography is crucial to the research in geographical education. Considering the sequence in human development research in geographical education for two levels of school should be conducted in more wide school-year span. Fourth, critical and prescriptive research in geographical education focusing on the individual, diciplinary, and social relevancy of the content of geographical education may be recommended. Finally, the outputs of the research in geographical education should be publicized more widely so that the rationale for justification of subject geography and geographical education may be shared with among the researchers, educational administrators, and practioners.

Objectives: This literature review was conducted to understand overall research trend and change in school health education during the past 20 years and to identify major outcomes and future directions of research. Methods: Descriptive literature review was conducted for school health education in Korea. A total of 117 peer-reviewed journal articles and thesis published between 1900 and 2008 (for 19 years) conducted in school were finally included in this review process. The research setting should be elementary, middle, or high schools and the major topic of the research should health education for students. Results: Research in elementary school was 38.0% which was greater than research in middle or high school setting. Surveyor intervention research was slightly increased in 2000s. General health and other review were the most frequently employed topics in 1990s' research and general health, smoking, and safety were in 2000's research, which implied that recently research specified its topics more than 1990s' research. Recently research was developed in intervention model comparing with 1990s' research. Research using experimental or quasi -experimental design seems having less intervention effects than the research using nonexperimental design. Conclusions: It is necessary that health education research in school focuses more in students' interest, participation, and factors related to intervention effects from now on.

The purpose of this study is to investigate research trends about elementary environmental education through the analysis of theses published from January, 1991 to June, 2011 in the scientific journals. For the analysis of theses, we set standards of analysis including the number of theses, research topics, research methods, the designs of study and the objects of study. The number of theses used for the analysis was 186 volumes by limiting as Journal of KOSEE (The Korean Society for Environmental Education), Journal of KASE (The Korean Association for Science Education) and Journal of KESES (The Korean Society of Elementary Science Education). The results of study are as follows. First, in the analysis of theses according to the published year, we discovered that the volumes of theses related elementary environmental education were more than 50% of theses published in the Journal of KOSEE since mid-2000s. Second, the theses about environmental education curriculum were most common topic in the research topics, and the next things were status and actual condition, environmental perspective, and theory and policy. Third, as the most common things in research methods and the designs of study, 38.6% of theses have focused on the 'development and application' as research methods and 50.5% of theses have used 'quantitative research' as the designs of study. Fourth, the most common study in the theses was to target elementary school students, then it was literatures, then teachers, and environmental facility. On the basis of the results of this research, we suggest that various studies and environmental education programs can develop student's right environmental perspective and teacher's recognition about environmental education must be presented.
