In the current era of mathematics education, constructivism is a core theory of learning. For teachers, understanding and applying constructivism to their teaching practices are crucial for student centered teaching. However, some mathematics educators understand Constructivism in a different way. For example, some future teachers view Constructivism as making mathematics 'fun' by creating game without considering conceptual understanding. In this paper, the original articles of Constructivism were revisited and investigated to understand and to search for their meanings. Also several types and sources of Constructivism were identified; Radical Constructivism, Vygotsky's social-cultural theory of development, Social Constructionism, and Social Constructivism. This paper investigated arguments of the several types of Constructivism and discussed their implications for mathematics teaching.

Purpose of this study is understanding of group modeling process focusing on constraints with geological field trip applied on social-construction of scientific model. This study was carried out on 12 students of 3 groups who participate in the study 'S' gifted education center. Students were conducted to theme of 'How was formation of Mt. Gwanak?' on 2 field trip classes and 3 modeling classes. Semi-structured interviews, all discourse of field trip and modeling classes, records of personal and group activity were analyzed to constraints based on theoretical background proposed by Nersessian (2008). Results as follows. First, sources of constraints are scientific knowledge, contents observed by students during field trips and additional materials things to be explained by model during modeling class with geological field trip applied on social-construction of scientific model. Second, there are 3 types of constraints to affect making group modeling. It is that shared constraint which used commonly by all the group members. It called selected constraint that used during the initial modeling and later were reflected on for use in the group modeling. And it is that generated constraints, which were not in the initial modeling but were used later in the group modeling. This study suggests that not only the constraints can help to understand of making group model through how they used but also show that example of learning with geological field trip on social-construction of scientific model to contribute school science.

The purpose of this study is to identify the relationship between the employees' perception of organizational justice and their prosocial behaviors, focusing on the moderating effect of employees' individualism and collectivism. The survey has been conducted for 200 participants working in Korean companies. The results show that the perception of organizational justice is positively related with their prosocial behaviors. Also, employees' individualism and collectivism is significantly related with their prosocial behaviors. Specifically, individuals who are more collectivistic or less individualistic performed more prosocial behaviors than those who are less collectivistic or more individualistic. Finally, employees' individualism/collectivism has moderated the relationship between the perception of organizational justice and prosocial behaviors. When employees have strong sense of collectivism, they performed prosocial behaviors consistently regardless of the perception of organizational justice. That is, even though they perceive organizational justice as low, they perform prosocial behaviors in some degree. However, when employees have strong sense of individualism, their prosocial behaviors have been significantly determined by the perception of organizational justice. That is, when they perceive organizational justice as low, they rarely performed prosocial behaviors. But, as they perceive more organizational justice, their prosocial behaviors have been dramatically increased. The implication of those results and future research questions have been discussed.

The purpose of this study is to figure out the characteristics of teacher's scaffolding that can promote the social construction of scientific models by analyzing a teacher's scaffolding that actually promoted the social construction in a real classroom context, so that we can better understand the teacher's scaffolding. For this study, a total of 32 middle school students and their science teacher in Seoul were observed and videotaped. The level of social construction were categorized in four stages. We divided the teacher's scaffolding by whether the level of social construction has changed or not, and analyzed teacher's scaffolding in each group. Teacher's scaffolding were categorized based on its object, purpose and means. The object were categorized into two types; small-group and individual. The purpose were categorized into two types; process-help and product-help. The means were coded into Diagnostic strategies(Reading, Listening, Questioning), Checking diagnosis and Intervention strategy(Instruct, Explain, Hint, Confirm). The result show that teacher's scaffolding is helpful in the social construction of scientific models when it supports small-groups more than individuals, and process-help more than product-help. It also shows that in diagnostic strategies, questioning and listening are effective. Finally, using checking diagnosis promoted interactions among students and a 'confirm' intervention strategy should be avoided because it has no positive effect on changes in the level of social construction. This study provides the features of the teacher's scaffolding that promotes social construction of scientific models in middle school classes.

The purpose of this article is to examine and assess the main issues in social constructivism with reference to the history of technology. Social constructivism, as an alternative explanation to technological change, has developed its points actively responding to various criticisms. Historians of technology have joined in dialogues with social constructivists through controversies about narrative vs theory, reliability vs performance, and evolution of bicycle. Social constructivists tend to use new jargons excessively, don't deal historical materials rigorously, and don't consider content-dependency sufficiently. To apply social constructivism to Korean cases many problems should be identified including the deficiency of historical materials, the importance of technological learning, and the peculiarity of relevant social group.

Study explores the effect of the member's social enterpreneurship at nonprofit organizations on cooperative behavior and proved the mediator effect of value congruency among individuals at those organizations. Examined on a nationwide scale with members at nonprofit organizations, this study indicated followings: 1. Innovativeness, Risk Management, and Social Mission. are valid 2. Innovativeness and Social Mission are related to cooperative behavior, 3. Value congruency with each other at an institution exerts positive effect on cooperative behavior, 4. Value congruency over social enterpreneurship and cooperative behavior partially, yet still positively, mediate social enterpreneurship to cooperative behavior. In other words, the higher the social enterpreneurship in each indivisual is, the higher the degree of value congruency among individuals is, leading to more frequent cooperative behavior. This study also suggests that enhancement of social enterpreureship in each individual at work through education should be considered.

The purposes of the study are to describe the feature of the program components, and to identify their changes in the process of designing the social work programs in the community service agencies in Korea. In order to achieve these purposes, the researchers constructed an analytical framework including 24 program components derived from the related literatures. Data was collected by questionnaires answered by the social workers who were in charge of the program development and implementation. Descriptive statistics analysis and factor analysis were applied to exam the features of the program components in 195 social service programs developed by the funds from the Community Chest of Korea and a private funding foundation. As the result of the analysis, the three noticeable features are found; (1) the agencies have very actively involved in the designing work in the process of developing practice guideline, however they have less involved in the designing work in the process of implementing program; (2) program components which are low level in design activities are intervention models, staff education, and practical ethics; (3) 8 categories of components derived from the theoretical perspective are reduced to 6 categories in the process for developing practice guidelines, finally to 4 categories in the process for implementing the programs. The implications of major findings were discussed in academic and practical perspectives in Korea, including future research works in the area.
