Nowadays, Web-based bulletin board system is widely used for e-learning because of its effectiveness in communicating and information sharing. But harmful or irrelevant contents are frequently posted and these affect students in learning community based on Web-boards and the ill effect of Web-board is revealed. Some Web-boards provide features that allow users can filter specific words to resolve this problem but those features have shortcomings. Using these features the content that contains harmful words is always removed even if the whole meaning of it isn't harm and user who uses harmful words habitually cannot have an opportunity of having his/her bad habit be corrected. In this paper, we proposed new way of dealing with harmful words that overcomes those shortcomings.

This study examined the effect of the SSI argumentation program based on social and emotional learning(SEL). The program consisted of 3 stages: (1) express their own feelings about SSI, identify the issues of SSI, and define a goal; (2) think of many possible solutions and envision results through argumentation; (3) select the best solution and make a decision based on warrants, data, and rebuttals. In each stage, the social-emotional strategies of self-awareness, self-management, social-awareness, relationship-management, and responsible decision making were used. Seventeen preservice biology teachers participated in this study during one semester dealing with four socioscientific issues. The results indicated that the preservice teachers, as time went on, became accustomed to expressing identifiable rebuttals, dispute talk, and asking questions. At the first SSI argumentation, argumentation mainly consisted of cumulative talk with no rebuttals, representing level 2 argumentation. Level 3 argumentation represented rebuttals that were implicit and weak, with cumulative talk. In level 2 and 3 argumentation, the preservice teachers represented understanding of others and compassion for self and others. Level 4 argumentation had rebuttals that were explicit, asking critical questions of the opposite sides. In addition, level 5 argumentation represented more than two controversial points with several instances of dispute talk. In levels 4 and 5, the preservice teachers became actively engaged in communication, inquiry self with others, managing vulnerability and negotiation.

The purpose of this study was to develop Home Economics(HE) teaching and learning process plans applied Problem Based Learning(PBL) focusing on 'food and nutrition' unit for students with intellectual disability and to evaluate the effects of the HE instruction on their food choice·management knowledge and problem-solving skills after implementing the instruction for students with intellectual disability. To develop HE teaching and learning process plans applied PBL focusing on 'food and nutrition' unit for students with intellectual disability, problems that arise in daily life to trigger interest of students were firstly developed. The selected problems and teaching and learning process plans were reviewed for validity by one home economics education professor and three teachers who are experts in special education. This study used the one group pretest and posttest design, sampling 6 students who are in special-education middle school with the intellectual disability. After HE instruction of 6 sessions applied PBL method, this study tested the effects of the instruction. The first three sessions taught how to choose and keep food. The fourth session taught purchasing food ingredients and keeping them for sandwiches. The fifth and sixth sessions let the students make sandwiches and give them to others. The instruments of the study comprised of tools for food choice and management knowledge, tools for problem-solving skills evaluation, self-evaluation sheets, evaluation form of course satisfaction for students, evaluation form of behavior in class for teachers, and daily observation journal and all tools. These instruments were proved to have reliability and validity. The results of this study are as follows. First, all six students who took HE instruction applied PBL method focusing on 'food and nutrition' unit scored 30 points higher out of 100 points after taking the instruction in food choice and management knowledge and scored 5 points higher out of 14 points in problem-solving skills on average. Therefore, it was interpreted that HE instruction applied PBL affected the food choice·management knowledge and the problem solving skills of students with intellectual disability. Secondly, the students with intellectual disability participated actively in HE instruction applied PBL focusing on 'food and nutrition' unit and expressed satisfaction. Three special education experts evaluated HE teaching·learning process plans applied PBL focusing on 'food and nutrition' unit to be well-developed. This study showed that HE instruction applied PBL focusing on 'food and nutrition' unit allowed the students with intellectual disability to acquire comprehensive skills in choosing, keeping, and making safe food and helped them solve problems of their life by themselves. Therefore I suggest that Home Economics should be adopted as a formal subject matter in special school curriculum for students with intellectual disability.

Recently, interest in Edu-Tech, which applies new technologies to the educational field, is growing. Edu-Tech is now being naturally used in schools, allowing both teachers and students to adapt to these changes. Particularly, there's significant attention on using Edu-Tech to bridge the educational gap through various teaching and learning strategies. This study focuses on the importance of self-directed task management by students for supplementary learning. It developed and utilized a math learning platform that enables teachers to easily provide and manage necessary tasks for students. Initially, the study developed "Sussam-MathTeacher" a problem-based learning application for middle school students, aimed at enhancing problem-solving abilities. This platform operates as a task management system, allowing teachers to assign or recommend problems to either the entire class or individual students. It aims to improve students' problem-solving abilities through a process that includes presenting necessary tasks, monitoring their own progress in solving problems, and self-assessing growth. Through this study, students demonstrated improved problem-solving skills by tackling tasks suited to their levels using "Sussam" highlighting the critical role of teachers in the digital educational environment.

In this paper, we propose an improved method of differentiated curriculum in social studies class that can be immediately used in the class. There are two major reasons that differentiated curriculum has not been applied to actual educational programs. One reason is the inefficient progress of differentiated curriculum derived from students' self-study based on individual projects and teacher's excessive investment of time in the development and management of individual researches. The other attribute is the difficulty in distinguishing students' academic level due to the lake of distinct criteria, because students are classified into merely two groups, in-depth group and supplementary class. To cope with these problems, we adopted a cooperative learning to enhance the educational effect of students of the similar level. Experimental results validate that the proposed method is effective in the course of social studies.

The idea that the mobile phone could be used in the education field recently comes from it's strengths. They have mobility, on-the-spot-study, portablity, immediacy and they are easy to connect to educational information. The application which I developed in this study is using Google-Map API and is based on GPS. It can share the information about the area where user is located like text data and pictures of geography, culture, and historical remains. This application makes the best use of the mobile phone's strengths. It's more effective and we can expect that users could manage resources of learning and do self-directed study in spite of being outside of the classroom or after regular classtime.

This study focuses on Social and Emotional Learning (SEL) as a theoretical perspective to provide education that enables adolescent students to understand themselves, establish healthy relationships with others, and form a healthy community. The meaning of learning and core competencies were analyzed. Results showed that the core competencies of SEL were all included in the nature, goals, subject competencies, core concepts, generalized knowledge, and achievement standards of the 2015 revised Home Economics Education (HEE) Curriculum. The implications for this are: First, the core competencies of SEL can be sufficiently cultivated through explicit education in HE classes without introducing a separate SEL program in the school field. Second, since HEE is a subject that emphasizes practice, the competencies of SEL can be applied in connection with actual life outside of school. Lastly, the effectiveness of SEL can be increased through HEE because the goals of SEL, which emphasize the connection between parents and the creation of healthy and safe community, are similar to the goals of HEE.

The purpose of this study is to identify the characteristics of school library services using the RGT (repertory grid technique), and to examine whether there are differences in the perceptions and internal experiences of school library services between human resources (librarian teachers, subject teachers, and librarians). I used indicators such as element intensity, construct extremity, discrepant constructs, and implicative dilemmas to analyze the characteristics of school library services. The elements of the repertory grid were set to 9, and 14 constructs were set through focus group interviews with 3 librarian-teachers. The GRIDCOR 6.0, which can be accessed online, was used to complete the repertory grid for 30 graduate students of the College of Education, and 6 of them were selected and analyzed, considering the demographic characteristics. From the perspective of element intensity, it was found that the following school library services are important and influential: resource management, teacher-librarian collaboration, and reading and information counseling services. The clarity of one's role, the actual performance, and self-regulatory ability were ranked high from the perspective of constructs intensity.
