In this paper, Atanassov's intuitionistic fuzzy set theory is used to handle the uncertainty of students' knowledgeon domain concepts in an E-learning system. Their knowledge on these domain concepts has been collected from tests that were conducted during their learning phase. Atanassov's intuitionistic fuzzy user model is proposed to deal with vagueness in the user's knowledge description in domain concepts. The user model uses Atanassov's intuitionistic fuzzy sets for knowledge representation and linguistic rules for updating the user model. The scores obtained by each student were collected in this model and the decision about the students' knowledge acquisition for each concept whether completely learned, completely known, partially known or completely unknown were placed into the information table. Finally, it has been found that the proposed scheme is more appropriate than the fuzzy scheme.

In the early 2020, COVID-19 changed the traditional way of teaching and learning. This paper aimed to explore the impact of college students' perception of course quality on their online learning satisfaction. A total of 4,812 valid samples were extracted, and the difference analysis and hierarchical regression analysis were used to make an empirical analysis of college students' online learning satisfaction. The research results were as follows. Firstly, there was no difference in online learning satisfaction among students by gender and grade. Secondly, learning assessment, course materials, course activities and learner interaction, and course production had a significant positive impact on online learning satisfaction. Course overview and course objectives had an insignificant correlation with online learning satisfaction. Thirdly, the total effect of online learning satisfaction was as follows. Course production had the greatest effect, followed by course activities and student-student interactions, followed by course materials. It was the learning evaluation that showed the least effect. This study can provide empirical reference for college teachers on how to continuously improve online teaching and increase students' satisfaction with online learning.

A number of research studies focus on the efficacy of using such as scenario based learning. However, desirable methods have not been introduced to assess the scenario based learning. This article is to suggest a fuzzy logic based framework for scenario base learning in which more reasonable learning effects are measured. It can be solved uncertain problems of linguistic variables. Also, we suggest three measures of accuracy, comprehensibility and completeness in order to evaluate accurate effects of scenario based learning. This assessment provides the scenario to the learner in which the scenario is presented in an authentic context, and enable the learner to reach an outcome through an adequate sequence and choices. This approach enables the system to present new scenarios and outcomes based on what a user selects. In particular, the application of fuzzy logic in scenario based learning can be easily pursued certain successful path or wrong path all the way through to reach major outcome in real situation.

This study is to point out importance of narrative as a way of learning values and interests for learners. Thus, geography value instruction models with narrative was developed and applied to teaching model. The results are as follows: First, narrative is useful to value education. Because narrative includes the contextual information, leaners are able to make a moral decision in respect of socio-cultural approach and to reach more truthful and practical decision with empathic understanding. Second, comparing with an expository text, the narrative text is more interesting, understandable, and preferred. Third, Web of meaning, one of scaffolding skills, is helpful to expand the scope of learner's thinking and group activity. Fourth, learner's awareness toward the topic changes. However, it is required to develop a practical method for elaborate assessment tool and for learners' active participation.

The purpose of this study was to design an interactive multimedia nutrition education program for preschoolers. Computer technology provides the opportunity to explore new and creative methods of delivering nutrition education to pre-schoolers. If this method is effective, more preschoolers can be reached with accurate and consistent nutrition education with less time and teaching staff. This program is a computer-based multimedia nutrition education program for pre-schoolers based on the Dick and Carey (Dick & Carey 2001) model of instructional design which includes analysis, design, development, and evaluation. The overall instructional goal was based on the needs of the target population. The needs assessment was a self-administered survey distributed to 1,426 parents of preschoolers, focusing on the need for preschoolers' nutrition education. The results of the survey indicated that parents wanted their children to learn reasons for eating nutritious food. Therefore, a program titled 'Nutrition Exploration' was developed with the instructional goal of teaching preschoolers the 5 Food Groups. To achieve this goal, the preschoolers were engaged in a game. They could earn colored jewels by completing the game in five sessions. The story line was that people living in a peaceful kingdom become sick after they lose the jewels. The learner takes an adventurous journey through five different countries to retrieve the jewels. These countries are 'Giwoon nahrah' (foods containing carbohydrates, such as rice and potatoes), 'Sangsang nahrah' (foods that are rich in vitamins and minerals, such as vegetables and fruits), 'Sooksook nahrah' (calcium-con-taming products such as milk), 'Teunteun nahrah' (protein-containing foods such as meat and fish) , and 'Gakeum nahrah' (products with high sugar and fat content, such as instant foods and soda). The learner who obtains five jewels in five different countries can save the kingdom. For the program to be effective and efficient, the multimedia had to be easy for the preschooler to enter, use, and exit. The verbal instructions enhanced child autonomy, and the program was developmentally appropriate so that the young child could easily manipulate the software. This research provides the basis for the continued development of computer-based nutrition education materials.

This paper proposes an item based learning system using e-mail in order to motivate learners effectively and avoid the bottleneck problem under highly competitive access situations such as the traditional web based learning. The proposed system has th ree features as follows: first, through e-mail, a learner receives test items depending on his/her level, submit an answer sheet, and then identify an assessment with help messages. Secondly, on the web, an instructor easily constructs item database without any other tools and monitors the status of each learner by identifying the learners' record. Finally, an easy-to-use interaction mechanism enhances the inter-activity between learners and instructors, and the usability of Q&A(Question and Answer) service by incorporating e-mail into the web bulletin board.

Purpose: The purpose of this study was to identify the relationship between the satisfaction with clinical practice and clinical performance ability by types of self-directed learning ability of nursing students. Methods: This was a triangular study that was conducted to understand clinical performance ability. The subjects were 260 junior and senior students from a university in P city. The data were collected from April 22 to December 30, 2015. Data were collected by Q-card, Q-block an assessment tool, a structured self-reporting survey and a questionnaire. Results: We classified the self-directed learning abilities into four types: Type 1: a self-reflective person; Type 2: a person who prepares for the future; Type 3: a person with a sense of responsibility and obligation; and Type 4: an enthusiastic learner. We found that clinical performance ability was higher for Type 4 than Type 3. We found that clinical performance satisfaction with clinical practice was also higher for the Type 4 individual than a Type 3 person. Conclusion: To improve students' clinical performance ability, we need plans and support to lead students toward becoming an 'enthusiastic learner' type of person with self-directed learning ability. It is necessary to increase students' satisfaction with clinical practice.
