In an effort to apply IT to practices of learning, universities are trying to implement e-Learning systems and expanding the extent of their usage. Nowadays, e-Learning systems are not only used for conducting web-based distance learning, but also used for supporting traditional classes education by encouraging communication and information sharing between instructors and learners or among the learners. There is relatively lack of studies on the exploitation of e-Learning systems in the traditional classes, in comparison with a distance education. Specifically, howe-Learning systems could support the traditional class and/or which benefits e-Learning systems could offer in the classes are among the important issues. In this study, we suggest that e-Learning systems would be the rich media to communicate and exchange information among people who participate in a class. We derive key variables like media richness and media experience from Media Richness Theory and from Channel Expansion Theory. Moreover, Media usefulness and Satisfaction of a learner with e-Learning system is drawn from the literature on IS success. We examine the effects of perceived media richness, media usefulness, and media experience on leaner's satisfaction with e-Learning systems. In addition, we also investigate learner's media usefulness perception which is positively related to media richness and media experience. Finally, learner's experience with e-Learning systems affects perceived media richness. Based on the results of an empirical test. we first suggest that perceived media richness with e-Learning systems contributes to increase media usefulness and satisfaction of a learner. Second, media experience is an important predictor of media richness and media usefulness perception. Consequently, the result can support Channel Expansion Theory. Finally, media usefulness perception affects learner's satisfaction with e-Learning systems.

In this study, science teachers' perception and attitude toward nanotechnology are examined through questionnaires gathered from 134 secondary science teachers. As a result, the study shows that science teachers have high perceptiveness. However, they do not understand specific information on nanotechnology correctly. Science teachers have positive attitudes toward nanotechnology and they have perceived risks of nanotechnology as well as benefits of nanotechnology. Science teachers show positive attitudes toward the application of nanotechnology, whereas they show negative attitudes toward personal information chip and nano-taste enhancer. Science teachers are exposed to nanotechnology via various sources such as TV and internet, whereas teachers rarely get information on nanotechnology-related concepts in textbooks and teaching resources. Science teachers have perceived many textbooks do not introduce enough nanotechnology-related concepts. Many teachers try to explain the nanotechnology when textbooks include nanotechnology-related concepts, whereas quite a few of teachers do not introduce the nanotechnology-related concepts in class.

It is commonly known that upper class house in Chosun Dynasty has characteristics of connecting space in combination with 'Chae' and 'Madang'. But living territory of traditional residence is connected each other by means of the necessity of dwelling life. So, it can be a fragmentary understanding about traditional houses to consider it as connecting space only from the viewpoint of visual perception. Residential space in later Chosun Dynasty is affected by practical life-style rather than building principle of 'Confucianism' due to the erosion of the caste system and the spread of the modern residential culture. So, it is necessary to consider dwelling life at that time in order to understand spatial characteristics of the residences. Researcher made an assumption that these characteristics were observed in the emerging upper class houses which appear in the process of change of the caste system rather than the traditional upper class houses. The researcher investigated connecting space from 'Bakat-ma-dang' to An-ma-dang of the emerging upper class houses in Gyong-gi province. The goal of this study is to find the properties of connecting space related to dwelling life of the emerging upper class houses in Gyong-gi Province. With this study, the followings are the characteristics of connecting space in emerging upper class houses in later Chosun Dynasty. First, 'An-ma-dang(Courtyard)' comes into close contact with 'Bakat-chae(Outer quarters)' which accommodate the complex functions, 'An-ma-dang' plays an mediating role between 'An-chae' and 'Bakat-chae' Second, 'Bakat-chae' generally encases 'An-ma-dang' which is central territories of dwelling life, and the men's area of 'Bakat-chae' considerably has opening space towards the outside. Third, 'Anmadang' plays an mediating role of male's and female's living territory, and it plays an important role in connecting space where labor forces are concentrated.

In this study, we suggested a strategy about a discussion class using Twitter, and experimented it inside an elementary school classroom. Elementary students participated in a panel discussion and the others discussed as audience using Twitter. After the discussion, we investigated the effectiveness of our strategy using the Technology Acceptance Model and verified students' satisfaction and ability to collaborate through giving them a questionnaire. As a result, the perceived ease of use positively effected the perceived usefulness and the perceived usefulness influenced the attitude and the attitude affect on intention to use. Also, students were satisfied with the discussion class on Twitter and had a positive perception about collaboration with it. As a result of regression, perception of collaboration among the students influenced the perceived usefulness positively. The results in this study show the effectiveness of using the discussion class strategy on Twitter.

The goal of this study were to look into the elementary school teacher's experience in the self-review of science class and analyze the changes of reflection level revealed in it. This study was a qualitative example research where two elementary school teachers participated and performed self-review via reflective writings regarding their science classes. Both teachers showed changes in aspect and frequency of review to a certain extend by reflective writings based on their class experience and the educational settings they are at. They all revealed a high level of changes on reflection by the feedback from the class reviews. Affirmative changes of cognition on science class and the perception of factors affecting the practice of the class such as understanding students, class observation of the peer teachers et al. contributed to the elevation of reflection level by continuously adjusting and complementing the practical knowledge through the reflection during or after the class.

The purpose of this study is to provide basic data for implementing library collaborative instruction (LCI) through investigating the effects of high school teachers' perceptions and experiences of school libraries on the recognition of LCI. To accomplish it, a questrionnaire survey of 198 teachers in 14 high schools in Seoul was conducted. As a result, teachers' perceptions of school libraries and school library experience had significant effects on the their willingness to implement LCI, which consisted of educational effect(EE), necessity and implementation plan(IP). In short, teachers' perception of school libraries influenced most variables in EE and did not influence necessity. All independent variables had significant effects on IP. This can be interpreted as that teachers recognize the need of LCI, but the perception of EE is influenced by conveying tool for the knowledge of LCI, such as education, promotion, and experience.

The purpose of this study is to analyze the effect of group co-learning on English reading ability and motivation and the change in group co-learning perception after planning and applying a group co-study class program that can be applied in university liberal arts English class. In order to achieve this goal, the experiment team (34 students) conducted the class from September 2 to December 13, 2019 for 62 freshmen who participated in the compulsory liberal arts English class at the four-year university in North Chungcheong Province, and the control team (28 students) conducted the class as a typical lecture class based on the basis of cooperative learning. The English proficiency of the learners was approached by dividing the area of academic proficiency into English reading skills and the area of justice into English reading motivations. The pre-experimental learners' English reading skills were measured by excerpting the national level educational achievement assessment (high 2). The research results are as follows. First, it was shown that the English reading ability score of a group that applied group cooperative learning and the English reading ability score of a group that did not apply group cooperative learning were statistically significant differences. Second, there was a difference between the English reading motivation score of the group applying the convocation group cooperative learning and the English reading motivation score of the group not applied. Third, the change in the perception of groups applying the convocation group cooperative learning occurred before and after the experiment. This study found that the awareness of English reading, English reading motivation, and cooperative learning increased through cooperative learning among university students during liberal arts English classes, which has a positive effect on self-identity and so on.

The purpose of this study was to find an implication for a direction to improve professional development in mathematics by exploring elementary school teachers' perception of the need for professional development in mathematics. To this end, 4 elementary school teachers were organized into one focus group, and group discussion materials were collected and analyzed based on cases of mathematics professional development needs. As a result of the study, the elementary school teachers' perception that the need for professional development in mathematics is both unnecessary and necessary. The perception of unnecessary was influenced by the easy level of elementary school mathematics content and the ease of teaching. Also, the perception of necessary factors were considering various aspects of mathematics teaching, changing the accumulation of failures in mathematics classes, maintaining authority of students, demand for class improvement due to social change, the impact of school work, the influence of the community of professional development and peers in school, and efforts to grow as teachers. Based on these results, the author discussed ways to promote teachers' participation in mathematics professional development by considering elementary school teachers' perceptions of the need of mathematics professional development.

Risk communication can be defined as the exchange of information about the nature, magnitude, significance, acceptability, and management of risk. The effect of risk communication on the perception and knowledge towards risk of environmental pollutants and it's related factors were investigated in this study. To investigate perception and knowledge of students and teachers towards risk of environmental pollutants, we conducted the survey using self-administrated questionnaire. The subjects were 574 for the first survey and 465 for the seconds survey from May to June, 2000. The main methods of transmission used in this study- through video tape, visual materials, question and answer, and participation in measuring pollutants - were not a one - way street. But an interactive process where information and opinions were exchanged among individuals, groups, and institutions. Environmental pollutants measured with participation of study subjects was Radon in the class room. The concentration of Radon was measured using E -PERM Device by installing it at each site for about 5 days. Subjects showed much interest in environmental pollution. Also, more than 98％ of total subjects were perceived as Korea is seriously contaminated at present. By risk communication activity, risk perception of all subjects about Radon was increased, on the other hand, risk perception of Dioxin was decreased except for elementary student. Moreover, knowledge of all subjects about environmental risk was significantly increased (p =0.0001) and effort of reducing environmental pollution was more increased (p<0.05). There is need to further develop, refine, and integrate these approaches environmental risk communication study, there is an even more pressing need to accelerate the diffusion of environmental risk communication practice into government and organizations.
