In this paper, we propose a plan for prospective early childhood teachers to plan, design, and produce and the results of operating a teaching model. To this end, we will identify video content for each age and video content of various topics and video playback time required by early childhood education sites, actively collect opinions from workers currently in early childhood education institutions, and suggest ways to develop on-site video content in the university curriculum. This requires prospective early childhood teachers to improve their self-understanding capabilities, community capabilities, and creative convergence capabilities, including digital capabilities. Through this, we intend to contribute to fostering smart early childhood teachers and creating a kindergarten activity and environment applying the latest video technology.

In this study, the effects of pre-learning attitude on learning participation and academic achievement was analyzed when applying the flipped learning methodology to engineering subject education. The modified PARTN teaching and learning model was applied, and pre-class survey, assessment on learning in pre-class, and post-class survey were conducted to analyze the effectiveness of flipped learning. The results were analyzed for 24 students who took the applied thermodynamics lecture. They were asked to take the course with the videos provided in the pre-class stage, and a pre-learning assessment was conducted to measure the completeness and understanding of the learning. As a result of the study, it was found that students with relatively excellent learning ability had excellent pre-learning evaluation results and excellent final academic achievement. In addition, the lower the pre-learning completion rate within the pre-learning period or the higher the learning rate using mobile devices, the more difficult it was to faithfully complete pre-learning, leading to poor pre-learning evaluation results. Meanwhile, the survey revealed that conducting pre-learning assessments were helpful in encouraging individual learning. In addition, cases reflecting pre-learning evaluation results to course grades showed higher pre-learning evaluation results than cases not reflecting pre-learning evaluation results to course grades, and in flipped learning classes, pre-learning evaluations act as a factor that promotes pre-class learning.

The purpose of this study is to research the effect of using analogies in high school earth science classes. According to the usage of TWA model, three types of teaching strategies were developed: text developer-generated, teacher-generated, and student-generated analogies. The model described in this paper began with a task analysis of highschool science textbooks for grade 10 to identify how the textbook authors used analogies to explain plate tectonics concepts. In this study, 210 students were sampled from first graders of high school. After 7 classes, the consciousness of students was investigated with questionnaires. The results are as follows: 1. Many plate-tectonics analogies are used in high school science textbooks (total 25). Teachers and authors construct effective analogies to help students build on their relevant knowledge by applying it to new knowledge acquired from textbooks. 2. Analysis of the data indicate that instruction using student-generated analogies was more effective than others. But in the class in conveying complicated concepts (ex. transform fault), teacher-generated instruction was effective. Teachers need to be aware of the weakness of using analogies in order to select the most appropriate analogies. 3. Making analogies in general, as well as using analogies have systematic steps. Analogies should be used after considering student's preconception, teacher's consciousness and text author's intention to use analogies as powerful instructional tools.

The purpose of this study is to systematically develop an impression management education program for career women by applying the Educational System Development Model [ESD] (Kwon, 1997) based on the research results of Hwang and Lee(2019) on social attractiveness. Since the previous impression management education programs were generally developed by content experts, few of them were developed systematically by considering the learner characteristics, clearly setting the educational goals, and structuring the contents accordingly. In this study, 'social attractiveness' defined by Hwang and Lee (2019) was considered as the educational goal of the impression management education program. In particular, this study focused on the design stage of the ESD model, set teaching goals based on the components of social attractiveness derived from previous studies, and conducted an analysis of teaching activities, the establishment of the educational goals at the specific function level, allocation of time, and establishment of an evaluation plan. The research process was intended to improve the learners' social image directly related to success through a systematic educational program designed to enhance the social attractiveness of working women with various hands-on activities and information. The impression management education program designed in this study has the educational advantage of a learner-centered education program configured to meet the needs and goals of career women. In addition, based on the ESD model, the sub-factors necessary for impression management were identified, and the curriculum was configured to reflect them through mutual communication between the instructor and learners. Therefore, this education program meets the basic requirements of impression management education necessary for career women and is expected to contribute to enhancing the social attractiveness of working women.

Purpose: An emerging trend in Asian higher education is English-medium instruction (EMI), which uses English as the primary instructional language. EMI prepares domestic students for international leadership; however, students report difficulty in learning, and educators have raised questions concerning the effectiveness of EMI. The flipped learning model (FLM), in which lecture and homework activities for a course are reversed, was applied to an English-medium course offered by a college of nursing in Korea. The aims of this study were to: 1) revise an existing English-medium nursing course using the FLM; 2) explore students' learning experiences and their acceptance of the FLM; and 3) identify key factors in the success of FLM. Methods: We used a descriptive, cross-sectional, mixed-methods design and the participants were students at one nursing school in Korea. A series of course development meetings with faculties from the nursing school and the center for teaching and learning were used to develop the course format and content. We conducted course evaluations using the Flipped Course Evaluation Questionnaire with open-ended questions and focus group interviews. Results: Students (N=75) in a 15-week nursing course responded to a survey after completing the course. Among them, seven students participated in one of two focus groups. Overall, students accepted and favored the flipped learning strategy, and indicated that the method enhanced lecture content and their understanding of it. Factors associated with effective instruction included structured monitoring systems and motivational environments. Conclusion: The FLM requires sufficient preparation to facilitate student motivation and maximize learning outcomes.

In our technology-driven world, various methods for teaching in an educational venue or in a simulated environment have been suggested especially for computer and coding education. In particular, IoT related education has been made possible owing to the industrial developments that have occurred in various fields since the Fourth Industrial Revolution. The proposed model allows various IoT systems to be indirectly built; it provides an inexpensive learning method by applying a simulation system in a 3D environment. The model is implemented on Virtual Remote IO based on the Arduino platform, thereby reducing the cost of building an education system. In addition various education-related content can be provided to learners through such an indirectly developed system. Test code was written to check the consistency of an operation between the real system and the virtual system.

The aim of this study is to design Spudsville, an immersive game environment in Minecraft that can effectively help learners acquire the English language. To create a successful learning experience using Minecraft, the researchers adopted the Agile Model and the Design Thinking approach. The researchers first conducted an analysis through an extensive literature review in order to assess the learners' needs. Afterwards, they designed and developed a Minecraft world based on the data collected during the analysis phase. The researchers learned that implementing constructivist and behaviorist approaches has benefits, even though applying a cognitivist-learning model to Spudsville could have provided the researchers with more insight on how learner processes information. Making these adjustments could improve Spudsville's effectiveness and could potentially help the ways in which gamified learning aids with language acquisition.
