Let me introduce a teaching method to improve practice capacity in dental laboratary work. I applied theories of layers of modeling and reflection constituting cognitive apprenticeship and peer tutoring to my class. At internet uploading a file showing a practice procedure a week before the class of a course, I let students preview it. During the class I demonstrated the practice procedure in front of students. A superior student and an inferior student paired according to the previous practice grade and a feedback between a peer tutor and a peer tutee was activated. Late in the class, a student self-evaluated his own practice result and had a check of a professor. Finally he compared his own practice result with that in the file uploaded at internet and reflected. This teaching method led to improvement in students' satisfaction and efficiency of learning.

This paper studies VPBL(Various PBL) models, applies them to classes, and analyzes results so that students of various majors can design and implement problems according to the characteristics of their majors in order to improve problem solving in education. VPBL performs the process of designing and implementing problems that reflect the characteristics of the major by applying constraints to the professor's programming language. The professor performs mini_class in the process of solving the designed problem and then shares it throughout. VPBL model apply results, The traditional teaching method was 3.51 points and the application of the VPBL model was 4.52 points, and "interaction, understanding of learning contents, and acquiring knowledge related to curriculum" were improved. In addition, VPBL has the advantage of expanding the learning range in the solving process as it is based on various problem solving, which has the effect of expanding the learning range compared to existing class models. Research on the expanded application of various SW liberal education in the future is required.

To train the model of the deep learning-based single-speaker TTS system, a speech DB of tens of hours and a lot of training time are required. This is an inefficient method in terms of time and cost to train multi-speaker or personalized TTS models. The voice cloning method uses a speaker encoder model to make the TTS model of a new speaker. Through the trained speaker encoder model, a speaker embedding vector representing the timbre of the new speaker is created from the small speech data of the new speaker that is not used for training. In this paper, we propose a multi-speaker TTS system to which voice cloning is applied. The proposed TTS system consists of a speaker encoder, synthesizer and vocoder. The speaker encoder applies the d-vector technique used in the speaker recognition field. The timbre of the new speaker is expressed by adding the d-vector derived from the trained speaker encoder as an input to the synthesizer. It can be seen that the performance of the proposed TTS system is excellent from the experimental results derived by the MOS and timbre similarity listening tests.

For the wide spread of cyber education, it is important to understand the instructional characteristics of cyber education and its applications in the educational sites which help to cope with the practical needs and problems. This study was conducted to analyze the experience of cyber classes(working hours, tasks and evaluation, satisfaction level and instructional effectiveness, suggestions for cyber education) and use of instructional methodology (instructional activities, interaction frequencies, cooperative learning activities, instructional activities toward knowledge building). The data was collected from pre-service teachers(403) and in-service teachers(318) in June 2004. The results were that pre-service and in-service teachers all consider the satisfaction level and academic achievement level of cyber classes lower than that of FTF classes. Particularly the boring presentation of instructional materials and the inadequate instructional strategies for cyber classes were the biggest complains, and lack of interaction among peer groups and with instructors, lack of learning opportunity for cyber instructional strategies, limited group activities, lack of interaction with experts were followed. Limited types of evaluation also showed that cyber classes focus on results more than the process of students' academic achievement.

Sports climbing requires repeated movements within a limited space, which may cause climbers to lose their constant interest in it. Furthermore, it is important that coaches should give lessons focusing on demonstrations to make sure that learners can understand the movements on their own, However, in traditional sports climbing lessons, they give instructions on almost every movement of learners' hands and feet. Hence, there have been constant calls for replacing these existing sports climbing lessons and presenting new methods to ensure that learners can observe their coaches' demonstrations in real time and emulate them. An introduction of the image training using spatial augmented reality techniques to solve these problems may have a positive effect on the improvement of learners' motor skills and attitudes toward lessons. This study aims to verify the effectiveness of the Climbing Character Animation (CCA) as a learning tool for sports climbing. To achieve this research objective, it applied it to actual sports climbing to verify its utility. As a result, it was shown that the lessons using spatial augmented reality-based CCA had a higher effectiveness than traditional sports climbing lessons in the degree of interest inducement, emersion and learning effects.

The purpose of this study was to examine the impact of a sense of classroom community and social presence on learning satisfaction in a cyber learning setting. The subjects in this study were 172 sixth graders in M elementary school in the city of D, who studied in a cyber setting at home. A survey was conducted to gather data, and multiple regression analysis were carried out to determine the influence of a sense of classroom community and social presence on learning satisfaction. As a result, it is found that a sense of classroom community and social presence had a significant correlation to learning satisfaction. A sense of classroom community turned out to affect learning satisfaction. A sense of classroom community are a major variable that should seriously be taken into account in an elementary cyber learning setting in order to boost the learning satisfaction of learners. In the future, the kinds of instructional design that could foster a sense of classroom community is required when cyber learning environments are prepared.
