The purpose of this study is to explore the factors that affect the intention to run remote classes after COVID-19 with university professors have fully experienced remote classes due to COVID-19. The research questions are what are the factors and the combinations of factors that affect the intention to run remote classes in the post-COVID-19. Data were collected through a survey of 311 remote classes at S Univ. in Seoul in fall 2020, and individuals and combinations of factors were confirmed through logistic regression analysis and decision tree analysis. As a result, individual factors were quality management, online office hours, quizzes midterm oral exams, video development, and student-student and instructor-student Q&A type between face-to-face and remote class. As combinations of factors, it was found that quality management×quiz×student Q&A and quality management×quiz×voting type had an effect on whether to run remote classes. Based on the results, we proposed to run and support remote classes in the post-COVID-19 era.

The purpose of this study is to compare and analyze the perceptions of TPACK for mathematics teachers who practice the technology-using lessons. In addition, by looking at the part where the perception is expressed in the actual class and the part where the difference of recognition can be revealed, it is possible to provide the direction to teachers who want to practice the technology-using lessons in the future. To do this, two mathematics teachers were selected using purposeful sampling. And we conducted research study and interview in order to analyze the characteristics of the teacher's general background and TPACK recognition, and we analyzed the video, the class materials, and the interview contents for teaching practices from the perspective of TPACK. As a result, the two mathematics teachers practicing the technology-using lessons were connected with the actual class situation focusing on the sub-knowledges of TPACK recognizes as having a lot of them. In addition, technology-based lessons were able to confirm that the functional capabilities of technology alone were not sufficient conditions to lead effective instruction. Finally, teaching method using technology has been confirmed that experience-based field practice can be more important than simply knowing mathematics content, technology, teaching method. Based on the results of this study, it is possible not only to provide methodological guidance to teachers who practice the technology-based instruction, but also to suggest the direction of TPACK research or the development of teacher training program in the future.

In this study, we investigated pre-service teachers' reflection of questions during science instruction in teaching practicum from the perspective of productive reflection. The productive reflection used in this analysis has four aspects of learners and learning, subject matter knowledge, instruction, and assessment. Five pre-service teachers participated in this study. They reflected on their questions with one class video by using think-aloud method. Semi-constructed interviews were also conducted. The analyses of the results reveal that the aspect of 'instruction' and the 'learners and learning' were frequently included in their reflections. 'subject matter knowledge' was often included in their reflection while 'assessment' was hardly included. The integrations of the two aspects appear most often, those of three aspects appear only sometimes. However, four aspects appear very rarely. The integrations of 'learners and learning' and 'instruction' with the other aspects were most frequent, and the integrations of 'content knowledge' with the other aspects were often. However, the integration of 'assessment' was very few. There were more productive reflections from pre-service teachers who reflect on several questions in context than who reflected on questions one by one. In addition, they exhibited some difficulties in suggesting alternatives to improve their questions. They tried to modify the teaching method related to the questions rather than revise the form of questions. Based on the results, practical implications to improve expertise related to the questions of pre-service teachers were discussed.

As a case study on the use of mentoring as a method of improving novice teachers' teaching professionalism in secondary science-gifted education, this study investigated the characteristics of mentoring science instructions for science-gifted students at the plan, performance, evaluation, and post-mentoring stages of the classes. One mentor and two mentees were selected, and mentoring in each mentee's instructions was conducted during nine classes over three times. We observed the total classes, and analyzed taped videos, the materials, the transcripts for mentoring and in-depth interviews, and field notes. The analyses of the results indicated that the characteristics of mentoring instructions, at the planning stage of the classes, exhibited the construction of more systematic classes, the escape from the schema that science instructions for science-gifted students were instructions using somewhat difficult experiments and the uses of diverse teaching strategies, the influence of the psychological burdens on developing science-gifted education programs, and the increase of the time preparing the classes. At the performance stage of the classes, the characteristics included the improvement in the quality of the classes, the influence of the psychological burdens on teaching the classes, and the inducements of some confusion on performing them. At the evaluation stage of the classes, the characteristics included the provision of the opportunities in deeply reflecting my own classes, and the provision of the practical power for improving the classes. Finally, the characteristics at the postmentoring stage could be attributed to the increase of mentees' self-confidence about their instructions and some development of mentors' teaching professionalism/mentoring skills.

This study examined the needs assessment of in-service education on teaching for school health teachers. The subjects of this study were 504 school health teachers, who were working in G-city and J-do. The data was collected from questionnaires of school health teacher's teaching from Nov. 9 to 23 2013. The data collected was analyzed by frequency analysis and a $x^2$-test. The conclusions were as follows. The first priority of the school health teacher's work is 'management of health problems' and the second is 'health education'. A difference was observed between the school levels (p< 0.01). The teaching methods mainly used on health care instruction were lecturing, discussion and practical training. The teaching materials of health care instruction mainly used were ppt, internet video, and textbooks. Most of health care teachers agreed to creativity education but they used creativity education less in practice. Most school health teachers want to in-service education on teaching and the contents of the course are creativity education or storytelling for new teaching.

In this study, as the viewing characteristics of users of YouTube video content related to science education, 'Inflow and Access' is analyzed to find out the interaction between learners and the system, and 'Reaction and Subscription' to find out the interaction between learners and contents. To this end, the YouTube channel "Elementary Science TV," was selected as the subject of research. The channel is mainly focused on the contents of elementary science textbooks, STEAM, and gifted education. The channel's data of YouTube studio was analyzed. The following results were obtained through data analysis: first, as a result of 'Inflow and Access' analysis, YouTube video content related to science education was most often introduced through external links, and the access device was mainly a computer. Second, as a result of the analysis of 'Reaction and Subscription,' 'like' and commenting performed as a reaction to the video were less than 1% of the number of views. Most users watch without a subscription, and watch for longer when using self-directed. Although this study was analyzed through a limited channel called 'Elementary Science TV,' we were able to discover a little about the users' viewing characteristics of YouTube video contents related to science education. In the future, it is expected that it can be used as a basic material for creating videos related to science education for remote classes, establishing a science education video platform.

In this paper, we describe a case study of a new lab. project that improves efficiency for education and interest on learning in image processing and pattern recognition related subjects by using LEGO Mindstorms. In addition we verify the validity with analysis of the practical application. LEGO Mindstorms is already used in many educational institution of several countries since about 10 years ago and various case studies have been published. The use of LEGO Mindstorms is generally positive but the negative comments about this exist. The main cause of negative opinion is from unpredictability. The unpredictability from mainly analog characteristics of robot can degrade the effective learning. The describing lab. project suppresses occurrence of unpredictability by minimizing dependence on robots. Students can concentrate on learning the related algorithms by minimizing the learning content and further consideration.

The advances in science technology brought about a new form of learning called flipped-learning: a combination of on-line and off-line learning. A flipped learning is a form of blended learning which has become quite popular, nowadays, in the field of education. Despite the emphasis on the importance of medical humanities in medical education program, there are no effective teaching and learning models to realize the purpose of medical humanities education. This study explores the possibility of flipped-learning to apply medical humanities classes. The class was designed based on the ADDIE model consisting of five stages, analysis - design - development - execution - evaluation. In order to do 'flipped-learning,' the instructor reconstructs the purpose of medical humanities education, instructional purpose and content, and analyzed learner. The contents of the medical humanities class were structured considering the purpose of the introduction to the medical humanities in the medical education program and the competencies that medical personnel should have in the developed health care environment. The instructor produces a video of the lecture and makes it possible to use LMS (Learning Management System) before and after classes, and conducts discussion activities so that learner-learner and learner-teacher interaction could actively occur during the class. The result of applying medical humanities lesson as flipped learning is as follows: First, it can realize the essence of medical humanities education. Second, it contributes to strengthening the competencies of health care provider. Third, flip learning can be used as a new teaching strategy for medical humanities education. The result of this study is expected to suggest new ways of introduction to teaching method in the traditional medical humanities class and contribute to the practice of designing and doing flipped learning of medical humanities class in the future.
