This study aimed to develop and implement a home economics education program with a travel theme for middle school students and investigate whether it improves their subjective well-being. The ADDIE design model was used to develop and implement the home economics education program titled 'Happiness Travel with You and I'. The program consisted of six sessions focusing on time management, dietary life, and housing life. The 'Happiness Travel with You and I' program was implemented for first-year male and female students at middle school B in Cheongju City. The results revealed that the program reduced negative emotions in adolescents and positively influenced their perception of the value of life. Students rated the program highly in terms of satisfaction with class content, class interest, and recognition of the importance of the class. This study is significant as it is the first attempt to test the effect of a travel-themed home economics education program and suggests the expansion and promotion of travel and leisure education in the field of home economics education.

One of useful strategies to change students' misconceptions into scientific conceptions in physics is the cognitive conflict strategy, the main point of which is to arouse cognitive conflicts by presenting anomalous phenomena to students. However, it has been reported that students experienced cognitive conflicts while expecting or reasoning results of an experiment before confronting an anomalous phenomenon. Therefore, we have examined how much students' cognitive conflicts were aroused before presenting an anomalous phenomenon. Then, we investigated the effects of the cognitive conflicts aroused prior to the students' confrontation with an anomalous phenomenon, both on the cognitive conflicts occurring after the students' confrontation with it, and on the students' conceptual changes. This study was performed during regular classes about light-source and weightlessness concepts. Subjects from two different middle schools in Pusan took part in the study. Preconceptions, degrees of cognitive conflicts before and after confronting anomalies, and postconceptions were checked during the classes. Then, delayed postconceptions were also checked in 3 weeks. As a result, the degree of cognitive conflicts before confronting an anomaly was as much as the degree of cognitive conflicts after it. There was significant correlation between both conflicts. Also the degree of cognitive conflicts before confronting an anomaly was a main factor in predicting the conceptual changes, while both conflicts had been related separately to the conceptual changes.

The purpose of the study is to investigate the effects of problem solving models and middle school students' recognition inproblem solving activities and to get implications of problem solving activities in science education. We took the position of problem solving as consisting of four sequential stages: search of problems, performance of the plan, presentation of results, and evaluation of the presentation. Taking into account thechosen activity factors for each stage of problem solving, we developed detailed activity tools that are supposed to guide the stage. Recognition of problem solving activities in 7th grade middle school students were positive. Students felt that problem solvingactivities made them engage more and interested in science classes, and that they were helpful in solving problems in everyday life. Even though they found real problems in everyday life, they preferred problem solving activities to deal with real problems rather than simple minded ones.

The purpose of this study is to investigate the effect of students' formation of evolutionary concept and learning on the development of digital teaching materials. The explanation of biological evolution, which explains the changes that living organisms undergo over a long period of time, can provide various contents for use in a book. The production and editing of images in digital textbooks would provide explanation of difficult concepts in a fun way. For this study, we designed instructional materials consisting of four class hours using iBooks Author, an electronic book authoring tool based on the 5E learning cycle model. In order to verify the effectiveness of the developed digital textbooks, we compared instructions by the general textbooks to those using digital textbooks. Both teaching through general textbook form and teaching using digital textbook materials had a significant effect on the formation of the concept of evolution, but interest in biological science and evolution increased significantly only in the group taught using digital textbooks. As a result of testing the instruction effect by the digital textbooks by classifying the students by type, the group that is familiar with smart devices was more active and interesting in class depending on digital literacy. The satisfaction of the developed digital textbooks also showed a positive score in the group with high digital literacy. The results of this study suggest that the development of digital textbooks in the unit of evolution can be an instructional material for easy and interesting approach to difficult concepts in the teaching of evolution.

The purpose of this study was to develop and implement a home economics convergence education program applying problem-based learning method focusing on the middle school food and nutrition life unit, and verify the effect of this class on the problem-solving ability of students. For this, the study set up the theme of 'sustainable life' by examining the relationship with other subjects, and set the key question as 'what is the relationship with the environment of food resources, the influence of individual level, and the solution method?' was postulated. And developed the problem and the total of 8 classes. As a result of conducting the convergence education program with home economics applying problem-based learning method, the pre-test and post-test scores were 3,54 and 3.96, respectively, which showed a significant increase in problem-solving ability (p<.001). There were significant differences in the dimensions of problem-solving ability, except for problem clarification. Therefore, it was confirmed that the home economics and convergence education program applying problem-based learning method is an effective class for improving students' problem-solving ability.

In this study, we examined the effect of socioscientific issue (SSI) based science lessons on underachieving 9th-grade students. A total of seven lessons centered on two SSIs related to the national science curriculum were developed and implemented during the first semester of 2021. Data were collected from 185 9th-grade students in one middle school in a mid-sized city of South Korea. Among them, 37 were identified as achieving far below the standards (underachieving students hereafter). Quantitative data were collected from pre- and post-tests on basic science content and attitudes and competency measures. To supplement quantitative data, lesson observation notes were recorded, and student interviews with a selected number of students were conducted. The analysis of quantitative data was conducted through the Wilcoxon Signed Rank Test and paired t-tests. Qualitative data were analyzed to find reasons for changing attitudes. The findings showed that the SSI-based lessons were more effective on underachieving students than the others in enhancing basic academic achievement, while there was no significant effect on all in attitudes and competency. Lesson observation data showed that underachieving students were more engaged in SSI-based lessons than before. Student interviews demonstrated several reasons why they were engaged, suggesting the aspects of SSI-based lessons that facilitated underachieving students' learning. Further research topics are suggested.

The aim of this study was to compare the effectiveness of microcomputer-based laboratory (MBL) with the traditional laboratory experiment on science classes in middle school. MBL tools were developed and applied for five experiment subjects chosen from middle school science textbook for MBL experiment classes, while usual experiment methods suggested in the textbook were used in traditional experiment classes. In order to evaluate the effects of MBL experiment class, achievement, graphic ability, science process skills, affective aspect related to science were tested before and after applying the MBL experiment. The result revealed that MBL experiment class was more effective than traditional experiment class in improving student's science achievement, science process skills, and graphic ability. The result also indicated that there was a significant difference between experiment and control group with regards to the effect on affective aspect related to science. From the above result, we can find the positive implication of applicability of MBL experiment as a new experiment tool at the early stage of introduction in a real context.

This study analyses the effects of the major educational policies, focusing on the private tutoring prohibition policy(PTPP), on the intergenerational class mobility(ICM) by using Korea Labor and Income Panel Study(KLIPS) 1st-12th surveys. Because private tutoring(shadow education) can be effective for academic achievement of children of above middle classes that spend most private tutoring expenditure and have more information on education, the private tutoring prohibition policy can increase the intergenerational mobility. This study confirms this possibility. Even when the overlapping effect of the middle school equalization polity is controlled for, there is still high effect of the PTPP. We think that we still need to examine the level of intergenerational mobility with PTPP cohort with that of later cohorts in the future. We also emphasize the compositive effect of the several consistent policies such as middle school and high school equalization polices and the PTPP and length and continuity of the policies for the higher mobility.
