This paper presents the results and gained experiences from the Project Based Learning (PBL) of magnetic component design within a Power Electronics Course. PBL was applied during the laboratory exercises through a design-project task based on a boost converter test board. The students were asked to calculate the main boost converter's circuit parameters' capacitor C and inductor L, and then additionally required to design and build-up the inductor L, in order to meet the project's goals. The whole PBL process relied on ideas from the CDIO (Conceive, Design, Implement, Operate), where the students are encouraged to consider the whole system's process, in order to obtain hands-on experience. PBL is known to be a motivating and problem-centered teaching method that gives students the ability to transfer their acquired scientific knowledge into industrial practice. It has the potential to help students cope with demanding complexities in the field, and those problems they will face in their future careers.

This study aims to apply the problem-based learning method to a college course on 'Consumer Studies' in a teacher education program. The participants of this study were 27 undergraduate students who were enrolled in the course. The PBL class was implemented for seven weeks using two problems: proposing special lectures on economic concepts and financial consulting. The effectiveness of PBL was analyzed through self-reflective journals, self-assessment, and a learning satisfaction survey of students. The result of this study was as follows. Students achieved the learning objectives and strengthened their collaboration and communication skills with team members during the PBL process. Moreover, students improved their self-directed learning and problem-solving ability through the PBL class. The results of self-assessment, in terms of learning task performance, active interaction, and self-directed learning were generally high at 4.63 points. In addition, the overall learning satisfaction level was very high, with a score of 4.75. The results will provide effective information on PBL classes to instructors and prospective teachers and will be used as data for learner-centered PBL classes.

This study aims to provide basic data for the development of teaching methods to improve the performance confidence of performing core basic nursing skills in nursing students while availing of online education owing to COVID-19. Data were collected from 146 students in the Department of Nursing at N University located in C city. The collected data was analyzed using descriptive statistics, difference, correlation analysis, and multiple regression by using SPSS 23.0 program.. The subjects' performance confidence of core basic nursing skills was dependent on self-directed learning readiness (r=.368, p<.001), intrinsic goal motivation (r=.232, p=.005), extrinsic goal motivation (r=.344, p<.001), task value (r=.237, p=<.001), control of learning beliefs (r=.262, p=<.001), and self-efficacy for learning and performance (r=.443), p<.001) with a significant positive correlation. The results indicate that the factors influencing the subjects' performance confidence of core basic nursing skills were the 4th grade (β=0.413, p<.001), extrinsic goal motivation (β=0.307, p<.001), and self-efficacy for learning and performance (β=0.316, p=.005), and the explanatory power was 35.8% (F=8.354, p<.001). The research results showed that it is necessary to develop and apply various online-centered teaching and learning methods to increase the extrinsic goal motivation and self-efficacy for learning and performance of nursing students to enhance their performance confidence of core basic nursing skills. This will serve as a basis for preparing effective online centered nursing education strategies to improve performance confidence of core basic nursing skills.

The paper is the principle of a curriculum, a recent method of teaching-learning in pedagogy, and intended for the exploration of the meaning of which reconstructs curriculum by narrative through practical exploration and narrative being discussed as the form of exploration. To date, Korean education showed an inclination of the traditional paradigm centered thinking and has emphasized the results by the method of scientific investigation. Even a curriculum reconstruction demonstrates documents that produce results without actually demonstrating the actual school setting. With communication one another is becoming increasingly important, we need the conversion of cognitive thinking that can express dilemma, contradictions, and complexities of the human world of which unexplainable by traditional paradigm mindset. Ultimately, the exploration of the direction that reflects a series of verbal, symbolic, and spiritual activities, which analyze lives of students, understanding and composing the meaning by using narrative, which talks about the experience of the human world in curriculums, is an important task for us.

While tools exist for blind people to understand shapes, these are not commercially available nor affordable and often require the assistance of sighted people. Thus, we designed two low-cost grid-based tactile tools using toggle buttons (TogGrid) and cotton balls (CottonGrid). To assess the potential of these as an educational tool, we conducted a user study with 12 people with visual impairments where they were asked to understand and reproduce shapes under different conditions. Although CottonGrid is relatively cheap and easy to make, findings show that TogGrid was perceived to be better in terms of perceived easiness, task completion time, accuracy, and preference in general. Particularly, participants valued TogGrid for enabling them to identify and correct errors. Based on the findings, we provide implications for utilizing toggle buttons for designing educational instruments for learning and expressing shapes for blind people.

This study is to present cooperative instructional concept framework for the library-based instruction of teacher-librarians, based on 'Information and the Library' curriculum and instructional design procedure. The development of cooperative instructional units has been initiated in the school libraries, but the research based on instructional theories, including instructional design, is lacking. In this aspect, instructional theories and methodologies for the cooperative instruction of teacher-librarians are important. The cooperative instructional units for teacher-librarians should be developed by 'Information and the Library' curriculum and instructional design procedures. The objectives of the curriculum emphasize information use process based on information task. This study is to present cooperative instructional concept framework, and to help teacher-librarians develop specific cooperative instructional units based on the framework.

It is very important for Academic purpose Korean leaner to understand main ideas and overall context of texts. In order to understand the overall context and mail ideas of text, learners need output task, ways to perform what they are learning, such as retelling. That would help them to realize that there is a gap between what they have understood and what they can actually speak or write. These out activities help learners comprehend the text more efficiently, while at the same time raising their confidence level. The purpose of this study was to develop an education plan to improve reading comprehension ability by using retelling activity. To achieve the purpose of the study, retelling activity, which makes it easier to take an integrated approach to language function and is considered to be relatively effective, was utilized because of the characteristics of retelling activity education instead of teacher-centered education methods.

This study examined how different types of remote video lectures, which universities are using in earnest now due to the COVID-19 pandemic, impact the academic achievement of learners. Zoom-based remote video lectures were divided into two types-general lecture-centered and group task-oriented-and experimental and control groups were set up accordingly. An achievement test and a questionnaire were conducted to determine how academic achievement differed between these two approaches. The achievement test revealed no significant differences in achievement scores between the two groups. Meanwhile, the questionnaire regarding satisfaction with Zoom-based video lectures indicated that both groups were highly satisfied. Participants in the general lecture-centered type group cited the effect of learning, their instructors' class preparation and attitudes towards the class, and the promotion of participation in learning activities as the causes of their satisfaction, while participants in the task-oriented type group highlighted communication and sharing, the efficiency of group discussions, and the moderate difficulty level of group tasks as the reasons for their satisfaction with the video lectures. Remote video lectures in the untact era are becoming increasingly common, and educators will need to develop various Zoom-based teaching strategies to maximize their efficiency.

The lecture is the main method of teaching, and the most common activity of students is 'listening.' Therefore, efficient and positive changes are expected if the researcher analyzes and uses students' listening styles to educate them. In addition, as the learner-centered education is emphasized, the learner's characteristics are becoming more important, and this flow increases the value of the listening styles of the student and that of the learning strategy, which is the student's self-directed learning. Therefore, this study examined whether there are differences in science achievement according to the listening styles and learning strategies by statistical analysis of the data obtained by conducting surveys for students in 5th, 7th, and 10th grades. The results of this study are as follows: First, students' listening styles and learning strategies show significant differences between men and women. Second, students' listening styles and learning strategies show significant differences between grade levels. Third, the level of task-oriented and critical listening types among listening styles produce meaningful differences in science achievement. Fourth, listening style, learning strategy, and science achievement have a significant correlation with each other. Finally, in terms of learning strategy-science achievement, it was shown that basic and complex cognitive strategy had a positive correlation with science achievement.
