Objectives: The aim of this study is to investigate extracurricular program needs according to the learning styles of dental hygiene students, and to develop and organize non-subject programs that strengthen student competencies. Methods: The subjects in this study were dental hygiene students from three colleges located in Chungbuk, Chungnam, and Ulsan, respectively. The survey tools were composed of learning style, a non-subject field, and non-subject teaching and learning methods. Lastly, 313 data points were analyzed. Results: Learning styles of subjects were as follows: assimilators, divergers, convergers, and accommodators, at 44.6%, 33.0%, 16.0%, and 6.4%, respectively. Preference of the non-subject field, according to learning style, showed that accommodators were higher than divergers on startup, and the difference was found to be statistically significant (p<0.05). Preference of non-subject teaching and learning methods, according to learning style, shows that both divergers and convergers prefer special lectures, while assimilators prefer tours, and convergers prefer experience/exercise. The results had achieved statistical significance (p<0.05). Conclusions: This study shows that dental hygiene students had different learning styles, and their learning methods varied depending on learning style. Therefore, a method should be identified to develop and run non-subject programs suitable for each learning style.

The knowledge-based society of the 21st century requires effective education and learning methods in each professional field because the development of human resource determines its competence more than any other factors. It is highly desirable to develop an intelligent tutoring system, which meets ever increasing demands of education and learning. Such a system should be adaptive to each individual learner's demands as well as the continuously changing state of the learning process, thus enabling the effective education. The development of a learning environment based on learner modeling is necessary in order to be adaptive to individual learning variants. An intelligent learning environment is being developed targeting the heritage education, which is able to provide a customized and refined learning guide by storing the content of interactions between the system and the learner, analyzing the correlations in learning situations, and inferring the learning preference from the learner's learning history. This paper proposes a heritage learning system of Bulguksa temple, integrating the ontology-based learner modeling and the learning preference which considers perception styles, input and processing methods, and understanding process of information.

The learning speed of the neural networks, the most important factor in applying to real problems, greatly depends on the learning rate of the networks, Three approaches-empirical, deterministic, and stochastic ones-have been proposed to date. We proposed a new learning-rate selection algorithm using an evolutionary programming search scheme. Even though the performance of our method showed better than those of the other methods, it was found that taking much time for selecting evolutionary learning rates made the performance of our method degrade. This was caused by using static intervals (called static windows) in order to update learning rates. Out algorithm with static windows updated the learning rates showed good performance or didn't update the learning rates even though previously updated learning rates shoved bad performance. This paper introduce a window control scheme to avoid such problems. With the window control scheme, our algorithm try to update the learning ra es only when the learning performance is continuously bad during a specified interval. If previously selected learning rates show good performance, new algorithm will not update the learning rates. This diminish the updating time of learning rates greatly. As a result, our algorithm with the window control scheme show better performance than that with static windows. In this paper, we will describe the previous and new algorithm and experimental results.

In this study we conducted a research regarding the effect on learning immersion and perception of the learning environment by learning presence of students in the Department of aeronautical science and flight operation in the context of non-face-to-face lectures caused by COVID-19. The relationship between learning presence (cognitive presence, emotional presence, and social presence) and learning commitment showed a high correlation. The learning immersion was also found to increase when cognitive presence, emotional presence, and social presence increased in multiple regression analysis to find out the effects of cognitive presence, emotional presence, and social presence, which are sub-factors of learning presence. The advantage of non-face-to-face classes was to be the ease of learning, and the disadvantage of non-face-to-face classes was the most difficulty of the learning process in the content analysis of the non-face-to-face class environment.

This study aimed to investigate how middle school teachers perceived major features of the 'Free Learning Semester'. In 2013, the Free Learning Semester has been proposed by Korean government to provide students with the educational programs which deals with various activities in classroom in order to increase student's learning ability. The Free Learning Semester helps students to figure out their dreams and develops their talents. The government plans to expand the Free Learning Semester to all middle schools by 2016. Since teacher's perception is an important matter in the application of the Free Learning Semester, this study seeks to document the changes in curriculum by observing the perception of teachers in the school that implemented the Free Learning Semesters and those that did not implemented the Free Learning Semesters. 172 teachers from nine middle schools in Busan that their school schedules allowed were surveyed. Two school which operated the Free Learning Semester were compared to seven schools which did not operate the Free Learning Semester. The results are summarized as follows: First, almost all (97.7%) teachers in the Free Learning Semester schools have completed a training whereas 74.6% of the teachers in the non-Free Learning Semester schools have not. The usefulness of the training was satisfactory, but the teachers in the Free Learning Semester Schools wanted more practical help with the curriculum. Second, the result, which was statistically significant(p<.05), revealed that the first grade second semester of middle school was the best time to implement the Free Learning Semester. In order for its successful establishment in schools, there needs to be a reliable and effective evaluation system. However, the results regarding the introduction and management of the new system were not statistically significant. Lastly, in the Free Learning Semester Schools, the changes in teachers' perception were statistically significant (p<.05). The results show that the teachers need the training and the teacher's community to implement the curriculum and set a basis for valuation.

개별화되고 적응화된 코스를 생성하기 위해서는 학습객체가 논리적 연관성을 가지고 연결되어 있는 기반구조를 갖추어야 한다. 이러한 학습객체간의 논리적 연관성, 그리고 개별 학습자를 고려한 다양한 링크를 통하여 학습의 각 시점에서 각각의 학습자는 서로 다른 학습경로를 제공받을 수 있게 된다. 본 연구는 학습과제 유형별 유의미 연결을 고려하여 학습객체 기반의 개별화 학습 시스템 구조를 설계하는데 목적이 있으며, 이를 위해 '관련성 요소 추출에 관한 연구', '학습목표 맵 구성에 관한 연구', '학습자의 인지상태 판단에 관한 연구'를 수행하였다. 학습객체 기반의 코스 설계가 단지 무의미한 객체들의 집합이라는 비판이 대두되는 시점에서, 본 연구의 학습객체간 관련성을 고려한 개별화학습 시스템 모형 연구는 e-Learning 안에 유의미한 학습과 진정한 교육을 담고자 하는 시도가 될 것이다.

The instructional influences of cooperative learning strategies, which emphasize mutual interdependency of learners, group goal, and individual accountability, upon students' achievement, the attitude toward science instruction and the perception of learning environment were investigated. Before instruction, the prior knowledge test about atoms and molecules, the test of attitudes toward science instruction, and the perception questionnaire of learning environment were administered, and the grade in the previous mathematics course was obtained. These scores were used as covariates. Mid-term examination score was used as blocking variable. For instruction, three different strategies-traditional individual learning, small group learning, and cooperative learning-were used and teaching materials for the units of mole and stoichiometry were also prepared. After instruction, the researcher-made achievement test, the test of attitudes toward science instruction, and the perception questionnaire of learning environment were administered. The perception questionnaire of group activities was also administered to the two treatment groups. In the quantitative subtest, the scores of cooperative learning group and small group learning group were significantly higher than those of traditional individual learning group. However, the cooperative learning group's scores in the achievement test and the qualitative subtest were significantly higher than those of small group learning group and traditional individual learning group. The students in the cooperative learning group were found to have the most positive perception of learning environment but to have similar attitudes toward science instruction. No interaction between the treatment and the level of the previous achievement was found in any of the analyses. In the perception questionnaire of group activities, students in both small group learning group and cooperative learning group exhibited positive perception of group activities. However, students in the cooperative learning group tended to think that their activities were related with their group's success. Educational implications are discussed.
