This study aims to analyze statistical tasks in Korean and Singaporean textbooks with the mathematical modeling perspective and compare the learning contents and experiences of students from both countries. I analyzed mathematical modeling tasks in the textbooks based on five aspects: (1) the mathematical modeling process, (2) the data type, (3) the expression type, (4) the context, and (5) the mathematical activity. The results of this study show that Korean and Singaporean textbooks provide the highest percentage of the "working-with-mathematics" task, the highest percentage of the "matching task," and the highest percentage of the "picture" task. The real-world context and mathematical activities used in Korean and Singaporean textbooks differed in percentage. This study provides implications for the development of textbook tasks to support future mathematical modeling activities. This includes providing a balanced experience in mathematical modeling processes and presenting tasks in various forms of expression to raise students' cognitive level and expand the opportunity to experience meaningful mathematizing. In addition, it is necessary to present a contextually realistic task for students' interest in mathematical modeling activities or motivation for learning.

The purpose of this study was to understand the substance of the reflective inquiry of students and obtain educational suggestion to the inquiry class for the promotion of the reflective inquiry, by checking out which characteristics the reflective inquiry showed according to the modes of interaction of small group in highschool earth science inquiry class. The result of study is shown as follows. At the stage of developmentand conclusion, the reflective inquiry relating the task context to data context was often appeared on the group of the modes of comfort interaction, but it was very rare on the group of modes of confrontation interaction. And the reflective inquiry scale value of the latter was two times lower than the former, The comfort group showed much more reflective inquiry statements quantitatively and performed much more meaningful reflective inquiry relating the task context to the data context. The heterogeneous group in the inquiry ability and the cognitive style showed confrontation interaction modes in the affective domain, having the most negative influence on the reflective inquiry. The homogeneous group both in the cognitive style and the inquiry ability showed the comfort interaction mode, having positive int1uence on the reflective inquiry.

수학 교육에서 수학 지식의 추상적 특성으로 인하여 수학 학습에 중요한 발생적 측면으로서 “concrete“ 에 대한 학습론적인 연구가 부족하였다. 또한 구체적 감각 조작 단계에서 형식적 추상적 조작 단계로의 아동의 인지 발달을 강조하다보니 ”concrete“와 ”abstract“의 통상적인 의미가 이분화 됨으로서 수학 학습에서 모든 연령과 수준에 무관한 상보적이고 상호 작용하는 가치를 수학 교육 연구에서 잊고 있었다. 본 논문은 발생적인 그리고 구성주의적 수학 학습에서 ”concrete”가 가져야 할 새로운 의미를 제안하였다. 새로운 의미의 “concrete“는 다양한 경험과 사물 그리고 지식과의 관계 맺음을 의미하는 ”connected“와 같은 맥락을 갖는다고 보고 몇 가지 수학교육에 관련된 의의와 중요성을 제시하였다.

The purpose of this study was to look into whether this mathematising learning utilizing realistic context has an effect on the mathematical thinking. To solve the above problem, two 5th grade classes of D Elementary School in Seoul were selected for performing necessary experiments with one class designated as an experimental group and the other class as a comparative group. Throughout 17 times for six weeks, the comparative group was educated with general mathematics learning by mathematics and "mathematics practices," while the experimental group was taught mainly with mathematising learning using realistic context. As a result, to start with, in case of the experimental group that conducted the mathematising learning utilizing realistic coherence, in the analogical and developmental thoughts which are mathematical thoughts related to the methods of mathematics, in the thinking of expression and the one of basic character which are mathematical thoughts related to the contents of mathematics, and in the thinking of operation, the average points were improved more than the comparative group, also having statistically significant differences. The study suggested that it is necessary to conduct subsequent studies that can verify by expanding to each grade, sex and region, develop teaching methods suitably to the other content domains and purposes of figures, and demonstrate the effects. In addition to those, evaluation tools which can evaluate the mathematical thinking processes of children appropriately and in more diversified methods will have to be developed. Furthermore, in order to maximize mathematising for each group in each mathematising process, it would be necessary to make efforts for further developing realistic problem situations, works and work sheets, which are adequate to the characteristics of the upper and lower groups.

The purpose of this study was to examine the need of the ideal human being and to establish ideal desirable state of affairs in the ideal portrait of a human being for pursuing in the home economics education. This study analyzed the deducted issue from the discussion about the human being in the educational research through the national curriculum and literature review. The desirable state of affairs established in this research are (1) it needs to reflect the feasibility aspect for actual implementation, (2) it needs to consider the contextual subject aspect, and (3) the curriculum view containing the philosophy of the subject, that is, critical science perspective shall be reflected on the desirable human being. The ideal portrait of a human being was stated, in the individual family, society nation, cultur e world according to subcategories. In addition, the stated ideal portrait of a human being was modified through expert consultations. The proposal was reexamined for the validity of the statement and restated as a comprehensive statement of an ideal portrait of a human being that included a restatement of the three areas. An ideal portrait of a human being pursuing in home economics education from a core value of curriculum stated as 'a person who has solved the practical problem actively'.

New Recently introduced to domestic market, MMA(Mixed Martial Arts) is growing very rapidly, thereby acquiring the property of sub-culture. With its proper function of providing dynamism and vitality, it also becomes the target of apprehension for its social dysfunction due to excessive violence. However, it is important to recognize MMA as a phenomenon and to understand the cultural flow inside MMA. It is required that the space where MMA is held should provide new experience in each contest. It is necessary to prepare very diverse productions for this purpose. While comprehension on this cultural and spatial phenomenon could mean one of starting point of space creation of space designer, it is necessary to study in the contextual aspect including historic and psychological approach. Thus, this study aims to understand one of the diverse meanings of modem space by investigating the space inherent in the phenomenon of MMA.

Diversification of college admission system has recently brought up the problem of system fairness. Studies on fairness of college admission system mainly focused on policy proposal or investigation of teacher's perception. Different from previous works, this study aims to analyze college students' perceptions of fairness of the current college admission system. This study used grounded theory and interviews from eleven students. Results of analysis are as follows. Causal condition proved to be frequent change in admission system happened in the course of diversifying admission criteria. The core phenomenon is fundamental unfairness in both procedural and substantive aspects of admission system. Contextual condition is information and infrastructure asymmetry among students which has a root in regional gap in Korea. Mediatory condition is advance of information technology and individual or group effort to overcome disadvantages. In conclusion, students consider that unfairness in college admission system reflects social structural problems that cannot be solved in a one-time prescription.
