The purpose of this study was to quantitatively evaluate the effectiveness of learning management systems (LMS) in the physical geography class. The study adopted the experimental design and three classes participated in this study. The first class was controlled using only classroom lectures, the second class used PPT slides along with the classroom lectures, and the third class used online video clips along with the lectures. The experiments were conducted from the Spring Semester 2007 to the Spring Semester 2008 for the introductory physical geography course. The study results showed that online learning tools help students improve academic performance and their attitudes towards the class and the instructor. Compared to simple PowerPoint slides, voice recording attached to the visual lecture slide materials enhanced students' motivation. Class lectures with lecture slides did not improve students' scores. However, when the visual materials were combined with voice recording, the number of internet access to online class materials increased, and class attendance and students' final grades were improved. Based on the results, the instructional design model that combines classroom and online learning was suggested.

The aim of this study was to analyze the levels of learners' participation and interactions both quantitatively and qualitatively based on the learners' choices of topic patterns in a process of online debate of a general subject and to explore the effects in order to suggest the ways for activating online debates. For this, it quantitatively analyzed the messages and the patterns in the online debate boards and supplementally implemented a post survey in order to investigate the participants' recognition on the factors of the learners' interactions and the effects. The given topic patterns were 'the presentation of one's opinion' and 'the presentation of pros and cons.' As a result of the analysis, the participating degree was higher in the pattern of 'the presentation of one's opinion' apart from the previous study. This study surveyed and, based on the result, it proposed the teachers should refer to the participants' tendency in advance. Also, it presented the deeper meanings on the interactions extracted by the results of the survey. The learners showed the strong dependence on the teacher' lectures or his materials and a variety of interactions with diverse objects. Besides, it is revealed that debates are helpful factors for enhancing learners' argumentative thinking, writing skills, and the knowledge about the subject in terms of the participants' recognition. Based on the findings, this study emphasized the teachers' educational roles and suggested the educational effects of the online debates in each class should be activated in this era of distance education.

Recently, Metaverse technology has emerged as an important topic in various fields. Metaverse refers to a three-dimensional virtual space in which social and economic activities similar to the real world are possible. Among the 235 third-year students who applied the Metaversity app in the radiology department of this university from September to December 2023, 200 participated in a survey to determine the difference in student response and satisfaction when applying the Metaversity app. analyzed. First, the most satisfactory VOD viewing method was viewing through the Metaversity app, followed by viewing through the LMS. Second, 'I think online videos are appropriate for holiday reinforcement.' showed the highest score at 4.35±0.60, 'I want face-to-face classes and online classes to be held simultaneously.' was 4.25±0.87, and 'I think meta. 'I watched it well through the Metaversity app' was the lowest at 4.10±0.30, and 'VOD viewing through the Metaversity app was used appropriately in class' was the lowest at 3.99±0.75. Also, there was no significant difference in the response to the teaching method (p>0.05). Third, in terms of satisfaction with VOD viewing using the Metaversity app, 'Applying the Metaversity app was interesting and fun' ranked the highest at 4.24±0.88. The score was high, with 'Better improvement is needed to actively utilize the metaversity app' at 4.00±0.45, and 'I hope the metaversity app is implemented in other remote classes' at 3.77±0.88. appear. 'VOD classes through the Metaversity app are better than the existing LMS method.' was found to be 3.44±0.66. Additionally, there was no significant difference in satisfaction with classes according to age and gender (p>0.05). The correlation between response and satisfaction with the metaversity app is 0.601, which can be considered very significant (p>0.001). As a limitation of this study, although we surveyed students' satisfaction with using the Metaversity app, we were unable to investigate the satisfaction of instructors who interact with students. In the future, we did not consider the instructor's satisfaction in classes using the Metaversity app. Research must be conducted, and universities must have institutional support and continued interest until metaversity apps are selected and used to prepare for distance learning.

In this study, we examined elementary school teachers' needs for environmental education (EE) in order to effectively implement EE in the elementary school. The participants were 113 elementary school teachers in Chungcheongnam-Do. Twenty items were adapted from the Environmental Education Needs test, and the teachers were asked to respond to each item on a 5-point Likert scale. For the items of the subcategory of EE training, teachers' preferences between the on-site and the online training were also asked. Although the teachers showed relatively strong needs for most items of both the subcategories of EE service and EE training, they exhibited stronger needs for the items related to the services and/or the content of training readily applicable to EE classes. Teachers preferred the online training to the on-site training in most items whereas their preferences to the on-site training tended to be relatively high in the items such as the use of local nonformal EE site, the development and the use of outdoor EE site, and the EE teaching strategies. Educational implications for the effective EE are discussed.

This study analyzed the expression of hanbok in online fashion styling games, and examined the main themes of and user reactions to hanbok fashion styling games through semantic network analysis and sentiment analysis. KrKwic, Textom, and NodeXL were used for data collection and analysis. The findings of the study are as follows: First, depending on the designer's expressive method, hanbok fashion styling games provide typical traditional hanbok, modern hanbok, and dress-like fusion hanbok, demonstrating contents with various themes for different sexes, classes, and situations. Second, as a result of analyzing the themes of hanbok-related styling game contents, it turned out that the main themes are tradition, color, historical drama, fusion hanbok, holiday, and love. Most of them produce modernized hanbok that reflect the situation and utility rather than strictly traditional ones. Third, as a result of analyzing user reviews of hanbok styling game contents, positive factors mostly turned out to be the satisfaction of the hanbok contents, with the users also showing positive intent to wear hanbok. Through this, it was found out that hanboks portrayed in game contents could potentially cause the user's positive intent to wear hanbok. Negative factors turned out to be the discordance between the intrinsic image of hanbok and the game character's image.

The main purpose of this paper is to examine the efficacy and future potential of a newly-emerging concept of a metaverse in online education environment. In order to achieve this goal, this paper showcases various scenes that happened in the metaverse classes using the ifland app. Through an in-depth analysis of theoretical grounds and preliminary survey findings of 32 university students, this study suggests that as students in a metaverse space are engaged in the interactive learning process and environment with an avatar that projects oneself, it can be an effective educational platform coming from the benefits of gamification and edutainment. In addition, a metaverse space provides existential encounters and hands-on experiences, which in turn increases the level of 3D learning immersion. It may overcome the shortcomings of online live streaming platforms such as Zoom or Webex that provide 2D experiences. Based on the findings, this paper further suggests a blueprint for online education suitable for the transition to a digital society.

This study is investigating the effectiveness of a blended learning for English listening and reading class by analyzing students' learning behavior. To this end, two surveys were conducted on a total of 75 students from the two different classes of Academic English Listening and Reading course. The research results showed that in the online class, the students built undesirable learning behavior such as solving listening quizzes by reading listening scripts or watching the instructor's lectures about the scripts and completing the assignment of summary of the scripts by referring to the Korean versions. In the offline class, the students' participation in group activities and attention to lectures was good. Therefore, it can be concluded that because of the students' poor online learning behavior, this blended learning was rather not effective. So the suggestions are discussed to enhance the effectiveness of the blended learning for English listening and reading.
