Mathematical knowledge is not exact definition but the supposition. Considering the nature of mathematics, realization of mathematics teaching which pursues critical thinking and rationality would be our problems. Accordingly, I set the subject of this study whether learning of constructivist discussion, which induces reflective thinking through communicating with others by expression with language of mathematical thinking in discussion, is effective against attitude on Mathematics and Mathematics achievement and study themes are as follows; A. Is learning of constructivist discussion effective against attitude on Mathematics? A-1. Is there any difference of self-conception on the subject between experimental group applied to learning of constructivist discussion and comparative group? A-2. Is there any difference of attitude on the subject between experimental group applied to learning of constructivist discussion and comparative group? A-3. Is there any difference of learning habits on the subject between experimental group applied to learning of constructivist discussion and comparative group? B. Is learning of constructivist discussion effective against mathematics achievement? The objects of study are 30 children of one class in the third grade of elementary school in Seoul for experimental group, and another one class with 30 children is comparative group. Study results and conclusion based on those results are as follows; First, students make reflective thinking through communication each other, therefore, instructor should create discussion environment for communication to express and form their mathematical thinking. Next, adaptability in student's mathematics activities and mathematical ideas should be permissible, and those should become divergent thinking. However, this study analyzed comparative results from only two each class having enrollment of thirty in the third grade. Accordingly, results from students in various grades and environment that are required to get more significant conclusion statistically.

우리나라는 그동안 세계가 놀랄만큼 빠른 경제발전을 이룩하였는데 그렇게 된데에는 무엇보다도 교육을 통해서 싸고 질좋은 노동력을 확보할 수 있었기 때문이라고 보아진다. 그런데 다가오는 21C의 변화는 인류사회의 관심이 산업 사회적특징에서 정보 사회적특징으로 전환되고, 가치관과 지식관도 근대 사회적 기준에서 초근대 사회적 기준으로 바뀌면서 새로운 전환기를 맞이하는 디자인 교육에도 많은 영향을 주고 있다.(중략)

This study investigated whether a song psychotherapy based on the change stages of alcohol addiction impacted the change readiness of alcoholics. The song psychotherapy intervention consists of six activities (listening to a song, singing, songwriting, song sharing, lyrics analysis, and discussion and analysis of a song), which considers the change stages of alcohol addiction. A total of 64 inpatients diagnosed with alcoholism were randomly assigned to either the control (n = 33) or experimental group (n = 31). The experimental group took part in the intervention program for 45 minutes twice a week for 6 weeks (total of 12 sessions). The intervention effect was evaluated with SOCRATES-K. The results showed that the SOCRATES-K score significantly increased by 14.6% (p < .001) for the experimental group, whereas it remained almost unchanged (0.8% increase, p = .141) in the control group. For subcategory scales, the experimental group showed the highest increase in the ambivalence factor, followed by the recognition and taking-steps factors. Meanwhile, no significant changes in all three scales were found in the control group. Therefore, the song psychotherapy intervention based on the change stages of alcohol addiction was found to significantly increase the change readiness of alcoholics.

SSI instruction can be an effective tool to promote key competencies for future citizens. Our assumption of the study is that applying the concept of collective intelligence in the context of SSI learning would facilitate the learning. Thus, we designed and implemented Collective Intelligence-based SSI instruction over almost a year and observed the effects of the instruction on enhancing students' collaboration, information management, critical thinking, and communication skills. Twenty 9th grade students enrolled in a science-gifted program voluntarily participated. Data was collected by administering a questionnaire to examine the skills before, in the middle of, and after the instruction, and by conducting classroom observations and focus student group interviews. The results indicated some degree of improvement in their targeted skills. First, they experienced the expansion of their thoughts by actively sharing information and ideas using the web platform. Second, they became more flexible and open to different points of views in order to accomplish a common goal. Third, they appreciated having independent time and space to explore their own positions on the issues and to search necessary information, and believed that the process encouraged them to more pro-actively participate and communicate in the group debates. Lastly, they positively perceived the values that collaboration with diverse group members could produce.

In this study, a TPACK-based STEAM program was developed and applied under the theme of excretory organs in the 'Structure and Function of Our Body' of the elementary science curriculum. The program was produced and conducted through curriculum analysis and learning goal detailing, learning environment analysis, teaching·learning method and technology selection, TPACK elements arrangement and teaching·learning material development, application and effectiveness verification. Teacher's TPACK considered in STEAM program design process is content knowledge (appearance and work of excretory organs), pedagogical knowledge (STEAM, problem-based learning, research learning, discussion learning, cooperative learning, scientific writing) and technology knowledge (3D printer and smart device application technology). The program consisted of a total of 8 hours of project learning activities and was applied to 29 students in the fifth grade as an experimental group. A program of the same theme developed mainly from textbooks was applied to 27 students in the fifth grade of a comparison group. As a result of the application of the program, the experimental group showed significant improvement in creative problem-solving ability and scientific attitude compared to the comparison group, and the class satisfaction with the STEAM program was also high. However, there was no significant difference in academic achievement ability.

This study aimed to reveal factors that contribute to the creation of collective intelligence (CI) and to provide a cornerstone for future studies on this subject. We hypothesized that effects of the complexity and meaningfulness of the task, diversity, openness to experience, independence, decentralization, and the use of information and communication technology (ICT) are preconditions for the creation of CI. To investigate these hypotheses, we surveyed 200 individuals in the research and development-based manufacturing industry and collected a total of 185 valid responses. The results of the analysis showed that the meaningfulness of the task, openness to experience, independence, decentralization, and the use of ICT had positive effects on CI. Both perceived dissimilarity and value diversity had negative effects on CI. When all variables were included, their significance for the creation of CI showed the following order: use of ICT, the meaningfulness of the task, openness to experience, perceived dissimilarity, and value difference. The theoretical and empirical implications of these results were discussed.

A major concern in the area of moral education is to find an effective educational method capable of supporting maturity of moral reasoning in young children. The purpose of the present study was to evaluate the effects of distributive dilemma discussion on children's distributive justice reasoning. The subjects were fifty 5-year-olds selected from a kindergarten in the city of Kumi. 26 children participated in a 10 week discussion intervention; another 24 children constituted the control group. The experimental procedure consisted of 3 parts; a pre-test to determine the experimental and control groups, moral discussions on dilemma situations based on 10 stories for the experimental group, and a post-test for both groups. The moral discussions were audio-taped. The results showed that children in the experimental group used more varied and elaborate distributive justice reasoning as the discussions proceeded. Moral discussions facilitated distributive justice reasoning.

This study aims to uncover sources of environmental learning from a student perspective using the previously unstudied case of South Korea. literature from other countries credits many sources of learning, including: media, school, personal sources, and non-governmental organizations. This analysis is based on focus group and questionnaire data collected during in-country field work. Results from South Korea are then compared with other studies carried out in the Asia-Pacific and the Western developed world. The results show that, similar to other countries including Australia, China, and India; South Korean students learn about the environment mainly through the media and schools. Television, schools, and domestic internet web pages were found to be some of the most-used sources of environmental information in South Korea, while more personal sources, such as community, family, and friends, were found to play an overall lesser instructive role. When compared internationally, South Korean students often exhibited less trust in the reliability of various sources, especially business, community, and foreign sources of information.
