The purpose of this study is to present a practical class design model that applies the problem-based learning (PBL) method to the subject of home economics. To begin with, a specific class model example was developed by conducting thorough document research and expert consulting. Two modules, named "Click! Global Leisure Environment" and "Happy Leisure Product Launching" were presented as the PBL questions. The case study focused upon in this research is an elective course called "Leisure Culture and Life Management". The 21 students enrolled in this course were considered in this study. Two teaching methods, namely a face-to-face teaching method and a web-based system "Snowboard" teaching method, were used to run the class. The research results are as follows: first, theoretical research and program development and demonstration were practiced with five different age groups: childhood, adolescence, university student, middle age, and senescence. Then, selfevaluation, peer evaluation, and group evaluation were conducted to motivate the students. Finally, a class evaluation was conducted by questioning the lecturer, who ranked well, scoring higher than or equal to 4.0 points out of 5.0 on all the questions. Through the PBL method, students showed an improved study attitude with more proactive participation in the class, they strengthened their communication skills and created a synergy with their team members. This study has significant meaning because it is the first research to apply the PBL method to home economics. Therefore, we expect other curricula to apply PBL and fully utilize this teaching method as well in the future.

This study aims to identify prospective elementary school teachers' perception of mathematical modeling in elementary class. Forty elementary school teachers participated in this study. Each teacher analysed the previous case studies about mathematical modeling in elementary class, developed a hypothetical learning trajectory, applied the hypothetical learning trajectory to his/her class, reflected students' learning and his/her teaching, and made reflective journals. These journals contained teachers' perception of mathematical modeling and the difficulties that teachers experienced in teaching mathematics as mathematical modeling. These journals were analyzed to identify teachers' perception of mathematical modeling in elementary class. This study shows that teachers have common features of mathematical modeling but their perspectives are little bit different, are classified into four kinds. And the difficulties that teachers experienced in teaching mathematics as mathematical modeling are classified into 5 categories; Task, Students' cognitive demand, Teacher' monitering, All students' participation, and Classroom culture. At last, suggestions for mathematical modeling in elementary class are done according to the result of this study.

This study aims to empirically structure the patterns of consumption and their effects on depression among the employed baby-boomers who were born in 1955 to in 1963. We used the 5th wave of Korea Retirement and Income Study(KReIS) in 2013 (n=2,585). The Latent Profile Analysis(LPA) estimated the empirical patterns of consumption and then a multiple regression analyzed the effect of consumption patterns on depression. The LPA results showed that the consumption patterns consist of four groups: Basic life-oriented class, Social life-oriented class, Home-based lifestyle class, and Advanced consumption-oriented class. The working baby boomers' depression was associated with their consumption patterns. Specifically, the social life-oriented class showed significantly lower depression than the basic life-oriented class and advanced consumption-oriented class. Other associates with higher levels of depression were found as lower education, having no spouse, lower self-rated health, higher levels of physical limitation, having a diagnosed disability, lower satisfaction with leisure activities, lower income, and lower subjective economic status in this study. Based on the results of this study, we propose the need for specialized financial intervention better for baby-boomers' retirement preparation in Korea.

The purpose of this study is to explore the current status and effects of online discussion classes in universities. To this end, a survey was conducted on university students attending a total of four universities in Seoul and Gyeonggi Province to diagnose their perceptions of the operation of online discussion classes and their effects. The collected data were analyzed using frequency analysis, descriptive statistical analysis, cross-analysis, F-test, T-test, and Scheffe test by applying SPSS program. As a result of the study, first, it was found that 'non-real-time recorded lessons' and 'real-time interactive video lessons' were mainly conducted at universities after the COVID19 crisis. Second, in the online class method, 'real-time interactive video class' had a positive effect on 'debate class preference' and was found to be more meaningful. Third, college students recognized participation in online discussion classes as a foundation for expanding creative thinking skills, suggesting that strengthening through smooth communication and exchanges based on learners' sufficient cognitive processes on discussion methods and procedures is more helpful.

We incorporated cooperative learning focusing on the 'Crustal Deformation' in five classes of second grade students, at an all-girls' middle school of Gimje city. The groups of cooperative learning were composed of four members of students each, according to the heterogeneous level. We conducted a pretest on the students' preference before incorporating the cooperative learning. After ten weeks of cooperative school work, the students took a post test with the same questions as the pretest. The result of this method greatly impacted the change on the students' scientific preference. It means that the students showed a positive change in their awareness of and participation in science classes, compared to before. However it is difficult to distinguish the differences in their scientific attitude on the recognition about scientists and habits which make them think scientifically. This resulted from the short period of ten weeks which is not sufficient to carry out the study strategy effectively. Surveys of the students on cooperative learning indicates that the middle level students prefer this method unlike the higher or lower level students. we are convinced that they can learn from the students of higher level and are able to help the lower level with the interaction through cooperative learning. According to the result of the survey, the method has some weaknesses; it arouses the high noise levels and consequent disturbance due to verbal interaction and of conflicts due to disagreements when they discuss the process. On the contrary, advantages are developing the students's interest in science class, helping them to learn, creating positive participation in class, and fostering mutual collaboration with other students through cooperative learning.

Due to the decrease in the school-age population, the number of freshmen at local college who lack basic learning skills is increasing. Thus, C college has been running a basic learning ability improvement clinic program. This paper is a case study that investigates the effect of basic learning ability improvement clinic programs on major class immersion, efficacy, and major class satisfaction. In 2022, a total of 459 students were surveyed, including 238 students who participated in online and offline classes for basic learning ability improvement clinics and 221 students who did not participate in classes. Data processing was performed using SPSS Ver. 26.0 was used. The results of this study are as follows. First, among the sub-factors of academic self-efficacy, the group participating in the basic learning ability improvement clinic showed significant differences in task difficulty preference and confidence. Second, the class participation group showed a significant difference in learning immersion in major classes. Third, the class participation group showed significant differences in all sub-factors of major satisfaction. In conclusion, it was found that the basic learning ability improvement clinic class had a significant effect on academic self-efficacy, learning immersion, and major satisfaction.

The purpose of this study is to investigate the effect of science writing heuristic class on 'seasonal change' on elementary school students' science learning motivation and scientific attitude. In order to carry out this study, 49 students from 6 grade of elementary school in P metropolitan city were selected and 24 students in one class were selected as experimental group and 25 students in the other class were selected as the comparative group. The experimental group was taught science writing heuristic in 10 times classes related to the 'seasonal change' and the general classes related to the 'seasonal change' were conducted in the comparative group. Based on the results of this study, the conclusions are as follows. First, the science writing heuristic class about 'seasonal change' showed a significant effect on elementary school students' science learning motivation for science class. This is analyzed as a result of the students being more familiar with their science class through science writing heuristic class. Second, the science writing heuristic class about 'seasonal changes' showed a significant effect on elementary school students' scientific attitude. This is because the science writing heuristic class offered elementary school students an opportunity to combine their experiences in daily life with the contents of the class. Third, students' participation, satisfaction, and interest in the science writing heuristic class applied in this study were high. Therefore, it seems to be effective if the science writing heuristic class is used for science class for elementary school students.

The purpose of this study was to provide the basic data for development of consulting model in elementary science class. For this, some questions on the teachers' perception for science instruction were surveyed to teachers : 13-item-questionnaires were given to 233 teachers in elementary school. The results of this study were as follows: Most of teachers were little understanding and experience of the science instruction consulting. They sensed that their science instruction were difficult, especially experimental activity in science class. They desired consulting mightly in their teaching methods for experimental activity. And it was found that most of them had a mind of consulting participation. Thus it is necessary to inform them the need of the instructional consulting. And in case of the development for the consulting manual, it should be consider the above results.

This paper recommends flipped learning as a method to improve the learning abilities and the level of software utilization when it comes to using computers in children education institutes. Flipped learning enables a class fully making use of the up-to-date multimedia-related technology. Especially, flipped learning leads a participation-oriented class rather than lecture-based ones. Young child's teachers can, not only improve their capabilities to utilize multimedia, but also manage classes that follow the trend of the fourth industrial revolution. Therefore, this paper introduces the importance of media education when it comes to training preliminary teachers and suggests a flipped learning curriculum. This paper finds significance in future efficient education for raising creative and integrated thinking children.
