  • The purpose of this study is to investigate the effect of environmental classes using EBS program on the environmental sensitivity and environmentally responsible behavior of 6th grade elementary school students. To this end, the 2015 revised elementary school curriculum was reconstructed for 6th grade students, and subject-centered environmental classes were planned, and EBS educational broadcasting environmental contents suitable for each class were applied and utilized. The conclusion of this study is as follows. First, this study analyzed the 2015 revised curriculum and reorganized the 6th grade curriculum and creative experience activities to plan the 22nd environmental class, specifying environmental sensitivity and environmentally responsible behavior that can have a positive impact on learners in each class. EBS educational broadcasting environmental contents that can be utilized were selected and environmental classes were conducted using them. Second, it was found that environmental classes using EBS educational broadcasting had a significant effect on improving the environmental sensitivity of elementary school students. The fact that environmental classes using EBS educational broadcasting goes beyond the spatial limitations of schools and informs that global citizens are interested in environmental problems and are working to solve environmental problems. Third, it was found that environmental classes using EBS educational broadcasting had a significant effect on elementary school students' environmentally responsible behavior. This is because environmental classes using EBS educational broadcasting do not stop at imparting knowledge, but suggest learning that leads to civic behavior, educational behavior, economic behavior, physical behavior, and persuasive behavior related to the environment.

  • This study aims to investigate the impact of science classes employing creative science drama on elementary school students' academic achievement and attitudes toward science during the final step of elementary science classes. The creative science drama used in this study is a class-closing activity wherein the teacher provides a basic script for the learning topic and then allows students to complete the rest of the story using their assignment. It devised a creative science drama class based on the research of Yoon (2016), and the contents of this study were centered on the use of magnets and the appearance of the Earth in the first semester of third grade. Students in their third year at H Elementary School in Gyeonggi-do were the subject of this study. The results showed that scientific achievement through science drama in the experimental class was improved, with a statistically significant difference. However, ANCOVA analysis revealed no statistically significant differences in attitudes toward science. Moreover, there was no statistically significant difference in scientific drama perception. Interviews with students in the experimental class applying science drama revealed that students found difficulty in writing science drama scripts and that coordinating and reaching a mutually acceptable opinion in group activities required the most discussion and cooperation. However, many of them stated that the experience of scientific drama was enjoyable and informative, and since what they learned was transformed into a scientific drama, they remembered the lessons longer.

  • Recently, with the introduction of drones, a core technology of the 4th industrial revolution, various convergence education using drones is being conducted in school education sites. In particular, drone theory and practice education is being conducted in connection with free semester classes and career exploration. The drone convergence education program has higher learner satisfaction than simple demonstration and practice education, and the learning effect is high due to direct practical experience. However, since practical education is being conducted for a large number of learners, it is impossible to restrict and control the flight of a large number of drones in a limited place. In this paper, we propose a monitoring system that allows the instructor to monitor multiple drones in real time and learners to recognize collisions between drones in advance when multiple drones are operated, focusing on education operated in schools. The communication module used in the experiment was equipped with GPS in Murata LoRa, and the server and client were configured to enable monitoring based on the location data received in real time. The performance of the proposed system was evaluated in an open space, and it was confirmed that the communication signal was good up to a distance of about 120m. In other words, it was confirmed that 25 educational drones can be controlled within a range of 240m and the instructor can monitor them.

  • This study aims to present implications for the appropriate establishment and development of a science-authorized textbook system through an understanding of the process of selecting science-authorized textbooks and analyzing the perception of teachers. Toward this end, this study conducted interviews with five elementary school teachers who participated in the science textbook selection process, surveys on 32 teachers, and analysis on the authors of the textbooks. The result demonstrated, first, that the "opinion gathering" stage was the most important one, and a council was formed in consideration of career and major. Moreover, the evaluation standard was reorganized and used according to the situation of the school. Second, in the process of opinion gathering, the teachers used a method for reviewing the entire textbook for each teacher. Inquiry activities and textbook composition (readability) were crucially considered as internal factors, and teaching and learning materials, such as videos, were deemed extremely important as external factors. The variable of the author, which is an indicator of the reliability and expertise of textbooks, was also recognized as vital. Third, the deliberation by the School Committee and the report by the principal were recognized as the administrative final step after selection. Finally, selecting the most suitable textbooks for each grade group was recognized as more important than arbitrarily unifying textbooks for the third and fourth grades and for the fifth and sixth grades.

  • This study investigated the level of academic passion for pre-service elementary teachers' science pedagogical content knowledge (PCK) and the factors that influence the passion. To this end, 182 first to fourth grade students in advanced non-science majors who were taking science-related courses in the second semester were selected, and two tests were then administered to evaluate their academic passions for science subject matter knowledge and science pedagogical knowledge. Individual in-depth interviews were also conducted with some of the participants. It was found that the factors such as "importance" and "harmonious passion" for learning science subject matter knowledge and science pedagogical knowledge were found at a high level. On the other hand, the factors such as "like" and "investment of time and energy" were slightly higher than normal, and the factor such as "obsessive passion" was slightly lower than normal. The differences in academic passion for science subject matter knowledge and science pedagogical knowledge were greater according to the high school track than the grade. The pre-service elementary teachers selected more often the factors such as "individual interests", "high school track", "contents of science-related courses at the university of education", "characteristics of professor in charge of science-related courses at the university of education", and "experience in teaching practicum" as the factors that influenced their academic passion for science subject matter knowledge and science pedagogical knowledge. However, there was a slight difference in the selection ratio depending on the high school track.

  • A RAM-based Neural Net(RBNN) which has multi-discriminators is more effective than RBNN with a discriminator. Experience Sensitive Cumulative Neural Network and 3-D Neuro System(3DNS) that accumulate the features point improved the performance of BNN, which were enabled to train additional and repeated patterns and extract a generalized pattern. In recognition process of Neural Net with multi-discriminator, the selection of class was decided by the value of MRD which calculates the accumulated sum of each class. But they had a saturation problem of its memory cells caused by learning volume increment. Therefore, the decision of MRD has a low performance because recognition rate is decreased by saturation. In this paper, we propose the method which improve the MRD ability. The method consists of the optimum MRD and the matching ratio prototype to generalized image, the cumulative filter ratio, the gap of prototype response MRD. We experimented the performance using NIST database of NIST without preprocessor, and compared this model with 3DNS. The proposed MRD method has more performance of recognition rate and more stable system for distortion of input pattern than 3DNS.

  • This study aims to investigate the online class preference depending on students' gender and school level. To achieve this aim, the study conducted a survey on 4,803 elementary, middle, and high school students in 17 regions nationwide. The valid data of 4,524 were then analyzed using the Apriori algorithm to discern the associated patterns of the online class preference corresponding to their gender and school level. As a result, a total of 16 rules, including 7 from elementary school students, 4 from middle school students, and 5 from high school students were derived. To be specific, elementary school male students preferred software-based classes whereas elementary female students preferred maker-based classes. In the case of middle school, both male and female students preferred virtual experience-based classes. On the other hand, high school students had a higher preference for subject-specific lecture-based classes. The study findings can serve as empirical evidence for explaining the needs of online classes perceived by K-12 students. In addition, this study can be used as basic research to present and suggest areas of improvement for diversifying online classes. Future studies can further conduct in-depth analysis on the development of various online class activities and models, the design of online class platforms, and the female students' career motivation in the field of science and technology.

  • 'Thinking and Expression' develops comprehensive problem-solving ability to solve various problems in life and society by cultivating thinking skills such as creative, logical, reflective thinking, and connected thinking and communication ability to communicate one's thoughts through writing and speaking. This is a college basic liberal arts course established to improve students. The purpose of this study is to introduce the case of rewriting of literature reading and healing performed as an extension of storytelling learning in 'Thinking and Expression' class. In class, we read Michel Tournier's short story "Let Joy Remain in Me" and shared our feelings about the final scene of the work. Then, we each presented a question that came to mind as we read the work, and we shared our thoughts with the members of the group. Next, the students created the content that will follow the last scene of the work with the direction of healing. Through this, we tried to read the work carefully and deeply appreciate its contents, and we had time to feel the creative experience of the reader re-creating the meaning of the work and the effect of healing rewriting. Then, we turned the direction of reflection to the realm of the reader's own life and expressed their desired future self in writing, imagining that it had already been realized. Through this, we tried to discover the meaning of practical rewriting towards self-actualization.

  • Concerns related to diversity are important throughout society, especially in the context of expansive globalization. In education, diversity-related issues require careful consideration to ensure social groups that have historically been marginalized benefit from educational opportunities. In this study, we investigated a case from within the United States aimed at addressing diversity issues in schools and discuss the implications of this study in relation to diversity issues in Korea. More specifically, we examined the features of the professional development program designed and implemented by the Smithsonian Science Education Center, as well as survey results from teachers who participated between 2019-2020. Our findings revealed that the program provided participants context specific experiences, space and time to develop an in-depth understandings of the causes of diversity issues and supports to attend to the various perspectives needed to set specific goals and action plans and to examine, refine, and revise their plans. Further, features of the professional development program had meaningful effects on participants' learning experience as they were supported to identify useful proposals and take action to solve their specific diversity issues. The findings from this study offer important implications for designing professional development and organizing supports to address varied current and future diversity issues in Korean school contexts.

  • In relation to differentiated mathematics education, Russia has a longer experience in research and practice than Korea. The mathematics curriculum for 10-11 grades currently in use in Russia is a level-specific curriculum and consists of a basic level and an advanced level. And in Russia mathematics textbooks for 10-11 grades are also textbooks for each level. In this study, we analyzed basic level textbook and advanced level textbook written by the same author group among the textbooks 'Algebra and Introduction of Mathematical Analysis' of the 10th grade in Russia. To analyze the main learning contents and textbook descriptions that were added in advanced level the 'real numbers' and 'complex numbers' sections were studied. The main contents of basic and advanced level textbooks for 'functions', 'trigonometric functions', 'trigonometric equations', 'conversions of trigonometric expressions', and 'derivatives', which are included in both basic and advanced textbooks were compared and analyzed, and the descriptive characteristics of the definitions and theorems presented in the two levels of textbooks were also compared and analyzed. From the results of this study, it is expected that various information on the contents of various level textbooks of mathematics, the differences between textbooks for each level, and strategies for the composition of textbooks for various level can be accumulated.
