Traditionally, the engineering field has been dominated by face-to-face education focused on experimental practice, but demand for online learning has soared due to the rapid development of IT technology and Internet communication networks and recent changes in the social environment such as COVID-19. In order for efficient online education to be conducted in the engineering field, where the proportion of experimental practice is relatively high compared to other fields, virtual laboratory practice content that can replace actual experimental practice is very necessary. In this study, we developed a line tracer model and a virtual experimental software to simulate it for efficient online learning of microprocessor applications that are essential not only in the electric and electronic field but also in the overall engineering field where IT convergence takes place. In the developed line tracer model, the user can set various hardware parameter values in the desired form and write the software in assembly language or C language to test the operation on the computer. The developed line tracer virtual experimental software has been used in actual classes to verify its operation, and is expected to be an efficient virtual experimental practice tool in online non-face-to-face classes.

The purpose of this study was to analyze pre-service chemistry teachers' view of learning focused on the influence of science education courses that pre-service chemistry teachers had learned. Three pre-service chemistry teachers were selected for this study. Documents related to science education courses, survey data about their view of learning and interview data were collected, transcribed and analyzed. According to this study, pre-service chemistry teachers had changed, modified, maintained and strengthened their view of learning while they took the science education courses. Pre-service teacher K and P had changed their traditional view to the constructive view and then had modified their view by adding the reality. And pre-service teacher H had modified his constructive view with some traditional view. All Pre-service teachers had modified their own view of learning because of the science education course that emphasized the real field situation. As discussed above, science education courses focused on the applying the theory to real teaching situation gave the opportunity to modify pre-service teachers' own view of learning. It implied that the science education courses learned in the teachers college have to include contents based on real teaching situation and pre-service teachers' reflective thinking processes for establishing their view of learning and customized teaching activities.

The purpose of this study was to develop a dietary life education program for adolescents and evaluate its effectiveness. The program was divided into three areas: 'Natam' (taste education), 'Wetam' (traditional dietary life education), and 'Gitam' (sustainable dietary life education), consisting of a total of 10 units primarily focused on cooking activities. For participants aged 14~17 years, face-to-face pilot education was conducted by a trained instructor once a week for 10 weeks. A questionnaire survey was performed to evaluate the educational effect(n=72) and satisfaction(n=82) during education period. Significant improvements were observed in knowledge levels for the 'traditional dietary life education', and 'sustainable dietary life education' which were identified as insufficient in the preliminary survey. Attitude and behavior levels were significantly improved across all areas. Satisfaction was high with a score of 4 out of 5 points for all areas. In conclusion, this program was found to be effective, and further emphasis should be placed on traditional and sustainable dietary life education to enhance its impact.

Compared with traditional face-to-face instruction, online learning causes learners to experience more severe feeling of isolation and results in higher dropout rate. This is due to the lack of interaction, sense of belonging, membership, interdependency, cooperation among members and social environment that enables persistence in online learning. Therefore, it is very important for grouping e-learning community to lower the dropout rate and eliminate feeling of isolation. In this paper, the research has been done on the inclination test list to be applied for grouping the desirable learning community. And on the basis of this research, the grouping system for e-learning community(GSE) based on intelligent multi agents for an inclination test using homogeneous and heterogeneous items has been developed. GSE system has such properties that construct a personalized user profile by an agent, and then make groupings according to users' inclination. When this system was evaluated, about 88% of learners were satisfied, and they wanted the group not to be disorganized but to be maintained.

Although many studies have analyzed and identified the importance of intrinsic motivation in the acceptance of information technology (IT), especially hedonic systems such as online game and online shopping, the acceptance of programming languages such as Java were not studied in a view of intrinsic motivations. The objective of this study was to investigate the effects of intrinsic motivation on the acceptance of programming language by the longitudinal analysis. In the service of the objective, we suggested the research model which included both intrinsic and extrinsic motivations and longitudinally extended by belief updating theory. For the validation of this model, the university students who participated Java class were surveyed twice, and the suggested research were analyzed by partial least square (PLS). In result, most of the suggested hypotheses were supported.
