  • The purpose of this study is to identify rural research topics, differences in research topics over time, and key mediators through the analysis of academic research trends using topic modeling. This study analyzed a total of 1,183 articles published in the Journal of Rural Planning and Rural Society over a 23-year period (2000-2022). We categorized rural research topics into 30, examined the proportion of research in each topic, and identified major changes in research topics over time. We also identified key words that mediate between research topics. The study found that, first, rural research trends can be categorized into five types (resources and utilization, area/space, people, ecosystem/environment, and tourism), with area/space being the most studied. Subtopics include rural amenities, rural disappearance/village miniaturization, and rural landscape management. Second, the research topics for each period were different. In the first period(2003-2007), the main research topics were rural amenities and Agricultural production- based climate vulnerability assessment. In the second period(2008-2012), the main research topics were Rural extinction and village depopulation, and rural landscape management, and in the third period(2013-2017), the main research topics were rural sixth industrialization and rural ecotourism. In the fourth period(2018-2022), rural development planning and rural life services(life SOC) were the main research topics. The significance of this study is that it extends the existing method of analyzing research trends and provides basic data to enhance comprehensive insights and understanding of rural research.

  • This study aimed to analyze the learning contents related to biotechnology in life science II and general engineering based on the 2015 revised national curriculum and discuss pedagogical implications for biotechnology education. The main findings were as follows: First, while the learning topics of life science II focused on the ethical aspects related to biotechnology, the learning topics of general engineering focused on the industrial aspects of biotechnology. Second, there were types of overlapping biotechnologies in the life science II textbooks and general engineering textbooks. However, the life science II textbooks provided more scientific and professional descriptions of biotechnology principles than the general engineering textbooks. Also, the life science II textbooks provided more specific overall explanations than the general engineering textbooks. There was a lack of ethical considerations concerning biotechnology in the general engineering textbooks. These findings imply that it is necessary to reorganize biotechnology content based on each school's curriculum and student characteristics.

  • The purpose of this study is to investigate how $3^{rd}$ and $4^{th}$ grade elementary students view about 'Science story', which is recently inserted in the new version of science text books. For the study, four hundred $4^{th}$ graders at four schools were considered in the area of Cheonan city, Chungnam province. The degree of student's preference, preferable science topics from the 'Science story', the reason for their preference, and their attitudes toward general science were examined. The study was initiated after student's reading of the 'Science story' (Advanced science, Science in the life, Science in the history, and Future science directions). The student attitudes toward general science were examined using questionnaire survey prior to others. The results of the study are summarized: First, the students who have more interests and affirmative attitudes about science subjects with high scores are more favored about 'Science story'. Second, generally the students prefer reading topics in the order of 1) Science in the life, 2) Advanced science, 3) Science in the history, and 4) Future science directions. However the order was flexible depending on student's gender, preference, and attitudes. Third, the student's interests about 'Science story' was mostly raised from the new scientific topics in the book. And it was also raised partly from their personal interests and usefulness for science learning. Based on the results of our study, we included some suggestions for the improved 'Science story' and their utilizations.

  • In this study, we analyzed the proportions of STS content, components, topics, and types of the activities of STS content in the elementary science textbooks developed under the 2007 Revised National Curriculum. The analyses of the results revealed that the percentage of STS content included was 15.9% by the number of pages, and 13.5% by the lesson hour. By the components of the STS content, the proportion of 'application of science', 'science-technology and our life' and 'social problems and issues' were large. Most STS topics were related to the 'effects of technological developments' and 'environmental issue', and the topics of 'family and population' and 'human engineering' were few. By the types of the activities, reading was the most, and investigation and writing were also found. Compared with those of the science textbooks developed under the 7th National Curriculum, the variety of components of the STS content increased, but the proportion of STS content and the variety of activities of STS content decreased in the science textbooks developed under the 2007 Revised National Curriculum.
