More flexible learning models are needed, and learning environments that operate through mobile technologies such as portable multimedia players(PMP) provide useful tools in implementing these learning models. The main attractant of PMP is often their versatility: being able to load and play different formats of video, audio, digital images, and interactive media. In this paper, we investigate the factors influencing the usage and acceptance of the PMP for study, based on the extended version of the Technology Acceptance Model (TAM). Based on data collected from online survey, we show that perceived usefulness, perceived ease of use, flow and perceived enjoyment are the major determinants for users to play PMP for study purpose. Factors, including ease of use, contents-credibility are shown to determine the level of perceived usefulness; additionally, perceived usefulness, ease of use and perceived enjoyment are shown to directly affect the level of flow. Based upon the statistical results, some useful guidelines for developing learning contents are also provided.

This study is a study of factors affecting pre-service teachers' learning immersion in online science classes. The results of a survey on the responses of 88 pre-primary teachers to online science classes were interpreted. In online science class, independent variables were set as ease, usefulness, and social presence, and dependent variables were set as learning immersion. Online science classes were conducted based on the university's LMS system. The results of the study were interpreted by regression analysis for t-test, correlation between factors, and multicollinearity test in pre-post-responses of pre-service teachers for ease, usefulness, and social presence. The results of this study are as follows. First, there was a significant effect in the before-and-after tests of factors in the online science class. Second, the correlation coefficient between factors in online science class is .306 for sense of community and mutual support and concentration at the significance level of .01, and .354 for learning immersion and open communication, indicating that there is a correlation. Third, considering the effective results of the pre-post test of each factor in the online science class, it cannot be interpreted that a particular factor had an effect, but it is interpreted that learning was immersed in ease, usefulness, and a sense of social presence.

The purpose of this study was to identify the variables that influence the intention of students to continue participating in SW education. Based on the TAM and reference to existing research on IT introduction, subjective norms, activity promotion conditions, programming related self-efficacy, perceived easy of use, and perceived usefulness were set as factors. We also tried to identify the structural causality between these factors and the intention to continue learning. The samples of this study were 204 elementary students participating in SW education. We collected our data by conducting web survey with these students for 1 month. Among the eight hypotheses set out in this study, the two hypotheses 'subjective norms will have a positive (+) effect on perceived ease of use' and 'perceived ease of use will have a positive (+) effect on Learning continuation intention' were rejected. The characteristics of the results are as follows. First, perceived ease of use indirectly influences learning intention through mediation of perceived usefulness. Second, in order to increase the intention of continuing learning, programming self-efficacy proved to be the most significant factor. The results of this study suggest that the usefulness of SW education and the programming self-efficacy of students should be improved for effective support of elementary school students' SW education.

인터넷은 학교 교육은 물론 기업의 교육을 변화시키고 있다. 인터넷을 학습에 활용하는 이러닝(electronic learning)은 1990년대 말에 도입되어 7년 이상 경과되었다. 이러닝은 오프라인교육(집체교육)에 비해 시간과 공간의 제약을 받지 않고 비용이 저렴하며 반복학습이 가능하다는 장점이 있다. 이러한 특성 때문에 이러닝은 지역간, 계층간 교육 불평등을 해소하면서 사회 구성원의 학습욕구를 충족시킬 수 있다. 이러닝은 평생교육의 일환으로 학교 교육은 물론 기업 교육과 사회 교육을 변화시키면서 점차 확산되고 있다. 지금까지 이러닝에 대해 연구된 논문들은 주로 이러닝을 사용하게 하는 주요 요인에 대해 초점이 맞춰져 있었다. 그러나 아쉽게도 이러닝은 초기에 기대했던 만큼 크게 확산되지는 않은 실정이다. 따라서 확산되지 않은 요인을 확인하고 이러닝 보급을 확산시킬 방안을 찾는 것이 매우 중요하게 부각되고 있다. 따라서 향후에는 이러닝에 대한 연구의 초점이 이러닝을 왜 채택하지 않고 있는가에 맞춰져야 한다. 이와 같은 연구의 필요성에 따라 본 연구에서는 이러닝을 왜 사용하지 않는가라는 기존의 입장과는 정반대의 관점에서 이러닝을 연구하였다. 본 연구에서 규명하고자 하는 주요 가설은 다음과 같다. 가설1: 이러닝 단점은 채택의도에 부의 영향을 미친다. 가설2-1: 이러닝장점은 채택의도에 정의 영향을 미친다. 가설2-2: 이러닝장점은 용이성을 통해 채택의도에 정의 영향을 미친다. 가설2-3: 이러닝장점은 유용성을 통해 채택의도에 정의 영향을 미친다. 가설3-1: 재미는 채택의도에 정의 영향을 미친다. 가설3-2: 재미는 유용성을 통해 채택의도에 정의 영향을 미친다. 가설3-3: 재미는 용이성을 통해 채택의도에 정의 영향을 미친다. 가설4: 유용성은 채택의도에 정의 영향을 미친다. 가설5: 용이성은 채택의도에 정의 영향을 미친다. 가설6: 용이성은 유용성에 정의 영향을 미친다. 본 연구의 대상은 자발적으로 이러닝을 채택할 수 있는 대학생을 대상으로 하였고, 설문 데이터 분석을 통한 실증연구를 수행하였다. 분석방법으로는 PLS 분석도구를 사용하였다. 분석결과 가설6을 제외하고는 모두 유용한 것으로 입증되었다.

The purpose of this paper is to investigate the effectiveness of Google Classroom (GC) and to examine the satisfaction of professors using GC as an online environment at a Mongolian University. Fourteen professors designed the lecture model and provided lessons using GC at D University for four weeks. GC provides new learning opportunities that are more efficient than face-to-face learning, because it can overcome the limitations of time and space. The results of the survey conducted with the professors who participated in the class to explore the effectiveness of GC show that the system provides: cooperation: 100% (strongly agree=7, Agree=7), personal learning opportunity: 100% (strongly agree=10, Agree=4), ease in learning: 100% (strongly agree=11, Agree=3), suitability: 100% (strongly agree=8, Agree=6), feedback opportunities: 100% (strongly agree=7, Agree=7), connection: 100% (strongly agree=7, Agree=7), accessibility: 100% (strongly agree=7, Agree=7), learning effectiveness: 100% (strongly agree=9, Agree=5), paperless experience: 100% (strongly agree=8, Agree=6). The professors who attended the class reacted positively to the use of GC, proving that the application of GC at this Mongolian University was appropriate and efficient. The use of GC is expected to help educational institutions strengthen and improve online learning, especially by breaking from traditional learning, and opening new paths for professors and students in Mongolia.

The purpose of this study is to understand students' use intentions of Web Based Collaborative Learning (WBCL) system. To meet this purpose, we developed a research model based on the Decomposed TPB. This model contains 5 influencing factors: Explicit social influence(EXSI) and Implicit social influence(IMSI), Perceived Usefulness (PU), Perceived easy of use(PEOU), Perceived Playfulness(PP). Data was collected 254 university students from two different institutions. Also, the analysis is conducted to do the hypothesis testing by using PLS 3.0. The result shows that influence factors except PEOU have a important and significant impact on user Behavior Intention(BI). Using WBCL system and learning tool, team leader(that is referent) and members can be a good interaction. For these same reasons, We found that especialy Explicit social influence(EXSI) and Implicit social influence(IMSI) are special influence factors in reference group.
