Video learning through YouTube has emerged as one of the most widely used instructional methods, yet relatively little research has been conducted on YouTube video users' willingness to use or behavior, so it is important to examine how to make and keep users' willingness to continue learning and to improve their retention rate for effective online learning. With reference to perceived value theory and utilizing an ECM perspective, the authors construct a model of YouTube video continuous learning intention and investigate the influence of perceived value and satisfaction on users' willingness to use YouTube videos for continuous learning.

The purpose of this study was to compare the differences between science teachers' preference and their students' awareness for teaching and learning methods according to classroom circumstance, with a focus on the 'Stimulus and Reaction' subject unit in middle school. A survey was given to teachers and students that concentrated mainly on the 8 grade 'stimulus and reaction' unit, it was followed by interviews with 5 students to and in the interpretation of the findings. The questionnaire participants consisted of 192 science teachers and 331 $8^{th}$ grade students. Lecturing was the teaching method which was most favored by teachers and mainly recognized by students followed by questioning, educational software and film/video. We could see difference of recognition between teachers and students from this result in application, review and attitude area. The teaching methods applied by teachers and recognized by students depended on the instructional situation. In addition, it was revealed that teachers were applying various teaching methods to classroom situations.

The purpose of this paper is to in vestigate a relative effectiveness of instruction among such three orienting methods as lecture, slide-tape and video-tape which the library of Duk Sung Women's University has applied for orienting the freshmen for the last three years. This research also carried out a sample survey by distributing uniform questinnaire to the three different groups of the students. Each group was oriented with lecture, slide-tape and Video-tape respectively. Finally, the empirical findings of this research are as follows: 1. All three orienting methods were useful for students to improve knowledge as to how to use the library, 2. There were a wide difference in effectiveness among three instructional methods, obviously, the slide-tape method was more effective in the orientation than the lecture method and, furthermore, the video-tape was more effective than the slide-tape one, Therefore, it seem safe to conclude that the media utilization effective in orientation program should be encouraged by the university libraries of Korea.

Although programming language is a core education area of software that is becoming increasingly important in the age of the fourth industrial revolution, as it requires logical thinking skills, it is recognized as a difficult subject even for SW major students. This difficulty occasionally causes SW major students to lose interest and confidence in their major during the introductory course of a programming language; making them change their majors, or give up their studies. In this study, we designed an instructional model using Scratch for educating C language which is a typical programming introductory language. To do this, we analyzed the concepts that can be trained by Scratch among the programming concepts supported by C language, and developed the examples of Scratch for exercising the concepts. The instructional model supports the progress model of learning first the programming concepts through Scratch and then expand the learning content into C language. We also conducted an experiment on the SW major freshman students of a local private university to verify the effectiveness of the model.

The purpose of this study is to develop contents and an instructional model that support children's dramatic play by integrating the robot and augmented reality technology. In order to support the dramatic play, the robot shows various facial expressions and actions, serves as a narrator and a sound manager, supports the simultaneous interaction by using the camera and recognizing the markers and children's motions, records children's activities as a photo and a video that can be used for further activities. The robot also uses a projector to allow children to directly interact with the video object. On the other hand, augmented reality offers a variety of character changes and props, and allows various effects of background and foreground. Also it allows natural interaction between the contents and children through the real-type interface, and provides the opportunities for the interaction between actors and audiences. Along with these, augmented reality provides an experience-based learning environment that induces a sensory immersion by allowing children to manipulate or choose the learning situation and experience the results. In addition, the instructional model supporting dramatic play consists of 4 stages(i.e., teachers' preparation, introducing and understanding a story, action plan and play, evaluation and wrapping up). At each stage, detailed activities to decide or proceed are suggested.

Background: Elderly patients visiting pain clinic may be at greater risk of misunderstanding the explanation because of age-related cognitive decline. Video instruction may provide a consistent from of teaching in a visual and realistic manner. We evaluated the effect of educational video on the patient understanding and satisfaction in a group of geriatric patients visiting pain clinic. Methods: Ninety two patients aged more than 60 years old who were scheduled for transforaminal epidural block were recruited. After exposure to either video or paper instruction process, each patient was asked 5-item comprehension questions, overall satisfaction and preference question. During follow-up period, number of outpatient referral-line call for further explanation was counted. Results: We observed significantly better comprehension in the video education compared with paper instruction (P < 0.001). Patient satisfaction was also higher in the video group (P = 0.015), and patients visiting pain clinic were more preferred video instruction (P < 0.001). Proportion of referral-line call for further explanation were similar (P = 0.302). Conclusions: Video approach to instruction process before consent improves treatment comprehension in geriatric patient visiting pain clinic.

This study explored the changes in the elementary science teaching expertise of teachers who participated in an in-school professional learning community for elementary science instructional research. Six elementary school teachers from grades 4, 5, and 6 at an 18-class S elementary school in a medium-sized city in Chungcheongbuk-do conducted collaborative instructional research on elementary science lessons as part of an in-school professional learning community, which was held 26 times over 7 months in 2020. During the professional learning community, video and audio recordings of the activities, research lessons, course materials, and professional learning community reflection activities were collected for analysis. The collected data were analyzed using qualitative research methods; data processing, reading, note-taking, description, classification, interpretation, reporting, and visualization; and the instructional professionalism elements were extracted based on the instructional professionalism framework. In the early professional learning community activity stages, the participating teachers first discussed their teaching perspectives, their experiences, and their goals for teaching science, which resulted in a selection of research questions. The teachers then collaboratively designed and implemented research lessons for each grade level, after which lesson reflections were conducted. The teachers' abilities to engage in qualitative reflection on the research questions improved after each reflection iteration. It was found that this professional learning community collaborative lesson study experience positively contributed to teaching expertise development. Based on the study findings, the implications for using professional learning communities to improve elementary teachers' science teaching expertise are given.
