The main purpose of this study isto explore the potential of affective computing (AC) platforms in education through two phases ofresearch: Phase I - platform analysis and Phase II - classification of academic emotions. In Phase I, the results indicate that the existing affective analysis platforms can be largely classified into four types according to the emotion detecting methods: (a) facial expression-based platforms, (b) biometric-based platforms, (c) text/verbal tone-based platforms, and (c) mixed methods platforms. In Phase II, we conducted an in-depth analysis of the emotional experience that a learner encounters in online video-based learning in order to establish the basis for a new classification system of online learner's emotions. Overall, positive emotions were shown more frequently and longer than negative emotions. We categorized positive emotions into three groups based on the facial expression data: (a) confidence; (b) excitement, enjoyment, and pleasure; and (c) aspiration, enthusiasm, and expectation. The same method was used to categorize negative emotions into four groups: (a) fear and anxiety, (b) embarrassment and shame, (c) frustration and alienation, and (d) boredom. Drawn from the results, we proposed a new classification scheme that can be used to measure and analyze how learners in online learning environments experience various positive and negative emotions with the indicators of facial expressions.

This paper describes an attempt to integrate flip teaching into a language classroom by adopting wikispaces as an online learning platform. The purpose of this study is to examine student perceptions of the effectiveness of using video lectures and wikispaces to foster active participation and collaborative learning. Flipped learning was implemented in an English writing class over one semester. Participants were 27 low intermediate level Korean university students. Data collection methods included background questionnaires at the beginning of the semester, learning experience questionnaires at the end of the semester, and semi-structured interviews with 6 focal participants. Because of the significance of video lectures in flip teaching, oCam was used for making weekly online lectures as a way of pre-class activities. Every week, online lectures were posted on the school LMS system (moodle). Every week, participants met in a computer room to perform in-class activities. Both in-class activities and post-class activities were managed by wikispaces. The results indicate that the flipped classroom facilitated student learning in the writing class. More than 53% of the respondents felt that it was useful to develop writing skills in a flipped classroom. Particularly, students felt that the video lectures prior to the class helped them improve their grammar skills. However, with respect to their satisfaction with collaborative works, about 44% of the participants responded positively. Similarly, 44% of the participants felt that in-class group work helped them interact with the other group members. Considering these results, this paper concludes with pedagogical suggestions and implications for further research.

중국 화장품 전체 교역중 약 67% 정도가 전자상거래로 이루어지고 있는데 특히 한국 화장품인 K-Beauty 제품의 인기가 높다. 기존 연구에 의하면 화장품 같은 소비재의 경우 소비자의 80%는 제품 구매 전 제품정보를 인터넷으로 검색하며 구전정보에 영향을 받는다. 대부분의 중국 소비자들은 화장품과 관련된 정보를 주요 SNS에 다른 소비자들이 올린 댓글을 통해 획득하며 최근에는 뷰티 관련 동영상 채널 정보를 이용하기도 한다. 기존의 온라인 구전 관련 연구는 대부분 Facebook, Twitter, 블로그 등의 매체 자체가 중심이었다. 본 연구에서는 온라인 구전정보의 전달 형태와 정보의 형태를 고려하여 정보유형을 동영상과 사진 및 텍스트로 나누어 연구하고자 한다. 중국의 SNS대표 플랫폼인 SINA Weibo와 동영상 플랫폼 Meipai의 비정형 데이터를 분석하고 온라인 구전정보를 양과 방향성으로 나누어 K-Beauty브랜드 매출액에 미치는 영향을 분석하고자 한다. Meipai에서는 총 약 33만개의 데이터를 수집하였고 SINA Weibo에서는 총 약 11만개의 데이터를 수집하여 화장품의 기본 속성도 고려하여 분석하였다. 본 연구의 의의는 온라인 매출은 K-Beauty화장품에 대해서도 구전에 영향을 받는다는 것을 기본적으로 입증함과 동시에 특히 정보 유형에 대한 구분을 시도 했다는 것이다. 두가지 매체 모두 기존 연구와 같이 양이 매출에 영향을 미치고 있으나 매체풍부성으로 인해 텍스트보다 동영상이 정보를 더 주고 영향이 크다는 것을 입증하였다. 또한, 정보 방향성 측면에서는 색조화장품의 경우 부정 댓글의 영향이 크게 나타났다. 실무적으로는 화장품 판매 전략 및 광고 전략에 기초 및 색조 화장품을 구분하여 중국 K-Beauty화장품 매출증대를 위한 마케팅전략을 구사하는데 도움이 될 것으로 기대된다.

This research is a case study about "Critical Thinking and Debate Education" class which was done for freshmen at the engineering college of "S" Women's University. Real time remote classes through LMS and ZOOM were the most effective tools under on-line circumstances, considering the fact that video lectures only cannot cultivate students' capabilities of critical thinking and communication. Throughout the analysis on students' self-reflection journals and lecture evaluations, this paper examined considerable future points and the pros and cons of "Critical Thinking and Debate Education" under online presentation and discussion situation. As research outputs, students told they could feel less nervousness and anxiety when they exercise and have a presentation because they could choose familiar space for them. In addition, students also told that they feel comfortable about both self-feedback and peer evaluation, repeatedly seeing the recorded video clip. However, on the contrary, sometimes students felt uncomfortable due to unstable internet connection through the online classes, and they also were regretful about the missing chances of interaction between a teacher and students and of intimate exchanges among students. They also told they had felt a kind of limit of enhancing their presentation skills just in front of the monitor. Considering these outcomes, this research paper points out that online education needs to be proceeded by strengthening multi layered feedback to students with the build-up of a non-face-to-face stable educational infrastructure, application of online instructional strategy, and utilization of YouTube platform and video contents. Through this research paper, I hope the new system of encompassing on/off line "Critical Thinking and Debate Education" and effective teaching and learning method can be developed soon by strengthening the strength of online education.

This study explored students' online fashion studio class experiences, and investigated the factors affecting their class satisfaction. An online survey of college students who were enrolled in online studio classes within apparel and fashion-related departments during the spring of 2020 was conducted in June 2020. Responses from a total of 213 participants were included in the final data. Respondents rated lecture clips as the most useful, followed by teacher demonstration and feedback, PowerPoint (PPT) supplements, and Q&As. Frequently mentioned areas of improvement were online platform stability and video quality. Many respondents also stated that more streamlined teacher-student communication channels, immediate and meticulous teacher feedback, the adoption of course contents developed specifically for an online environment, and provisions for equipment usage would be desirable. Student satisfaction of an online fashion design studio class was significantly affected by teaching presence, social presence, online learning system stability, perceived usefulness of teacher's demonstration, and affective response toward COVID-19. Students satisfaction of an online garment construction studio class was significantly affected by teaching and social presence, online learning system stability, and perceived usefulness of teacher's demonstration. Based on these findings, we recommend developing teaching contents and methods that allow students to feel included in class and establish an online system with various functions to enhance the sense of social connection that can enable two-way communication.
