The purpose of this paper is to investigate a new method for activating the metacognitive abilities that play a key role in the Mathematical Problem Solving Process (MPSP). The proposed research question is as follows: Can the MPSP activate metacognitive abilities of high school students in the pencil-and-paper environment using guidance material for metacognitive activities\ulcorner To solve this question, two case studies have been carried out. Two students for the study were selected via informal interview. They voluntarily took part in 13 experimental lectures. The activating paths of their metacognitive abilities in the MPSP were chronically described and analyzed. All the activating processes of the students focusing on the aspects of metacognitive behaviors were analyzed by means of interview, observation, self-report, and activity data. The two high school students participating in the MPSP voluntarily recognized and reflected their deficiencies in metacognitive abilities, and therefore maximized their own performance. They made quite significant progress in the course of activating their metacognitive abilities through voluntary participation and gained greater confidence in the MPSP. Hence they have become good problem solvers. They expressed not only the factors influencing their behavior but also their self-awareness during the metacognitive activities. In the long run, this experiment will increase possibilities for the internalization of the metacognitive process.

The study is a preliminary study of the effectiveness of the structured cognitive behavioral arbitration program targeting elementary school students who perform high risk problems based on schools for convergence with local communities. The program is designed to be practiced by semi-trained professionals. To screen high-risk students, total 102 students were tested K-CBCL and those who scored over 60T on problem behavior syndrome scale were recruited. 32 students were selected and devided into intervention group and control group. Intervention group was received 90-minutes-sessions per week, for nine weeks. The program was done by graduate students and undergraduate students majoring counseling and supervised by school psychologist. The internalization group showed significantly lower score in Internalization, anxiety/depression, and externalization group showed externalization, aggressive behavior. but mixed group didn't showed significantly lower score. Implications of the results, limitations and suggestions for future study were mentioned.

Tar Baby, Toni Morrison's fourth novel re examines the problem that black characters face in negotiatiating a place for themselves within a dominant culture, with respect to their own history and culture. The novel critiques the dominant socio economic and commodifying cultural space from which the black woman seems to have no escape. Jadine is a colonized subject, for as a fashion model she has surrendered to an aesthetics of commodification, and as a student of art history, she has internalized the capitalist ethic of the white culture industry. Though she has ensured her freedom, Morrison's critique of her separation from her family and culture is unmistakable. Interwoven with her narrative is Son's predicament, the stereotype of a black racist and her 'lover'. The novel ends with him at the crossroads of culture, yet signaling his passage to freedom through resistance. The paper arguments how Toni Morrison has envisioned the welfare of African American community by reconstructing the role of new black generation, as represented by Jadine and Son, whose new journey towards their self fulfillment just not only bring their personal freedom but also regenerates African American community by resisting dominant commodifying cultural.

The present waste problems require a change of thinking with regard to conventional economics. It has been generally believed that competitive markets maximize social welfare. But, the other hand, a few economists argue that "the competitive markets cannot always be relied on to provide all goods in the efficient amount." One of the best examples of the latter contention is the environmental problem. What is the basic thinking of the conventional economics that causes this problems \ulcorner What is the present problem that requires the change of conventional economic thinking \ulcorner The environmental problem result from the conventional economic thinking such as pursuing the limitless of the Gross National Product(GNP), believing the increasing returns in economics of scale and the efficiency of competitive market. This economic principles, howe- ver, does not apply currently to public goods, especially environmental amenity and natural resource because the price of markets does not reflect the natural goods of services. We call this eternality. Externalizes are no considered by either buyers or sellers of goods of which production or use results in an eternality. This leads to market failure are causes an waste problem in the economic activities. Today, it is almost impossible to say in a word what the solution for waste problems is because they are by-products complicated and entangled human activities. In this paper, I have introduced the causes of environmental problems only from the economic point of view. I have also described the needs of conversion of conventional economic thinking. Firstly, sustainable development, maintaining the natural resources, should be the basis of the economic growth rather that pursuing the limitless growth of GNP. Secondly, an appropriate scale of human's production activity should be taken into account to reduce the impact to the natural environment. Thirdly, internalization of eternality is asked to correct the market failure. This requires the public policy such as imposing a talsubsidy, assigning a property right or implement a more detailed environmental quality standard through, because use of the natural resources can be. allocated optimally by the intervention of government or social associations.

The purpose of this study was to investigate whether group play therapy is effective in reducing problem behaviors of children with developmental disabilities. The subjects of study were in special schools and 5 children with disabilities using short-term care centers for the disabled, The research period was 12 sessions of 40 minutes twice a week using winter vacation from January 2, 2018 to January 28, The measuring tool, K-CBCL, was used to observe behavioral changes qualitatively. The summary of this study is as follows. First, children with disabilities significantly reduced their aggressiveness, atrophy, depression, and anxiety, and increased their activity during each session. Second, problem behaviors decreased after the intervention of group play therapy, and there were more decreases in internalization problems than externalization problems. The results of this study suggest that group play therapy is meaningful in reducing problem behavior according to the individual characteristics of children with disabilities.

This study examined an instruction method for the improvement of information processing abilities in elementary school students. Current elementary students are required to develop information processing abilities to create new knowledge from this information flooded age; however, there is a shortage of instruction strategies for these information processing abilities. This research proposes a method for information processing ability based Barrow's problem-based learning model, and was applied to real elementary students. Students developed an improved ability to create new knowledge and to present relationships with information through the process of problem solving. This study performed experimental research by comparing pre- and post-tests for twenty-three fifth grade elementary students over the course of eight months. This study produced a remarkable improvement in information selection, information reliability, information classification, information analysis, information comparison, and information internalization.

Since the problem-based learning (PBL) shows the effectiveness of self-directed learning ability and internalization of learning motivation in the process of solving real problems, studies on PBL and application cases are actively pursued in the university education. This study analyzed the effects of PBL on the academic achievement and computational thinking in a non-SW major students' programming course. The programing course was divided into the PBL class and non-PBL class, and at the end of the classes, the scores of the exams and the results of questionnaires about the educational effectiveness and computational thinking were analyzed. As a result, the students in the PBL class, compared to those in the non-PBL class, showed significantly higher scores in the areas of the algorithm implementing skill, self-directed learning, problem solving ability, and continuous learning motivation.

The purpose of this study was to examine the mediating effect of young children's self-control in the relationship between mother's affectionate parenting psychological behavioral control and young children's problem behaviors. The subjects of this study were 368 mothers whose young children were 3 to 5years old and attending to 3 private kindergartens and 2 child-care centers located in Chunkbuk. Data were analyzed by frequency, percentage, Primary factor analysis, Cronbach's ${\alpha}$, t-test, F-test, Pearson's correlation, and hierarchical regression, using the SPSS 12.0 program. The results of this study were as follows: First, young children's self control partially mediated when mother's affectionate parenting affected young children's internalizing and externalizing problem behaviors. Second, young children's self control partially mediated when mother's psychological control affected young children's internalizing and externalizing problem behaviors. Third, young children's self control did not show a mediating effect on the relationship between mother's behavioral control and young children's internalizing and externalizing problem behaviors. In conclusion, young children's internalization of mother's psychological control and behavioral control as well as affectionate parenting have its effect on problem behaviors.

Programming is excellent tool on realizing ideas. However students often complain of difficulties due to requiring the strict programming grammar and the highly thinking. Although various researches have been conducted to teach the programming easily for students, it should precede the analysis of what and why programming concept is difficult for learners. In this study, we analyzed what and why the programming concept is difficult for novice learners in basic programming education. Based on the results, we suggested: improving problem-solving skills based on accurate understanding and internalization on the programming concept, on reducing error between thought and execution results through the creation of sophisticated algorithms and on offering a variety of troubleshooting experience, establishing strategies to think freely for problem-solving process, and promoting the effectiveness of the learning through the learning procedure design.

Objectives ： The purpose of this study was to evaluate gender differences with respect to the internalization or externalization of symptoms according to the amount of time spent engaged in extracurricular education. Methods ： The study included a community sample of 755 boys and girls (mean age, 6.6 years), collected from five elementary schools in Gunpo, South Korea. Primary caregivers completed a questionnaire which included information on demographics, the amounts of time children spent in extracurricular education and with other activities, and an adapted form of the Behavior Assessment System for Children (BASC-2). Gender differences regarding externalizing and internalizing behavior problems were examined according to extracurricular education. Results ： With respect to the boys, there was a difference in the frequency of those who had externalizing behavior problems according to their time spent in extracurricular education. In contrast, the girls exhibited no difference. With respect to those children who spent a lot of time engaged in extracurricular education, there was a gender-specific difference only with respect to externalizing behavior problems. Conclusion ： A gender-specific difference exists only in terms of externalizing behavior problems according to time spent engaged in extracurricular education.
