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.

Citizens should be sensitive to the complex and controversial SSIs (Socioscientific Issues), be able to make a responsible decision with evidence and empathy, and furthermore take political action for the larger welfare. The premise of this research is that understanding the nature of science (NOS) takes an important role when students and adults participate in the discourse on SSIs because SSI reasoning requires individuals to examine information and counter-information with skepticism. We therefore designed SSI programs that were incorporated with NOS by adapting a contextualized-reflective approach. The leading research question was to what extent SSI contexts contributed to promoting students' understanding of NOS. A total of 71 11th grade students participated in this program. The school was located in an urban city near the capital city of Seoul, South Korea. We designed SSI programs to cover the issues of genetically modified organisms, climate change, and nuclear energy. Each issue required four to six class periods to complete. We conducted pre- and post-program tests using the revised VNOS-C, recorded group discussions or debates and collected student worksheets to observe the increase of student NOS understanding. As a result of this program, students showed moderate improvement in their understanding of NOS.

This paper explains how the basic and instinctive emotion "joy" is verbally expressed in Russian and Korean. In particular, the main concern of this pater is on the cultural context with which the emotion "joy" is related and the ways in which the emotion "joy" has a wide range of uses. The semantic and pragmatic characteristics of the uses of the expression "joy" can be explained through the cultural and historical backgrounds in both languages. In Russian, joy has two variants, radost' and udovol'stvie. It is very difficult to distinguish a significant difference between them; however, the former is mainly connected with more mental, spiritual, cultural, and religious contexts, whereas the latter is mainly related with more concrete, instantaneous contexts and daily life. The former produces an impression that has a more wide, spiritual, and macroscopic attitude toward a situation, whereas the latter produces an impression that has a microscopic and instantaneous attitude toward a situation. Compared with the Russian expressions, the Korean equivalents, 기쁨 and 즐거움, have a very similar opposition like that of the Russian. The former is based on a more logical and causal relation between an anticipation or desire and the current situations, whereas the latter is based on the participation of speakers in a situation and has a very instantaneous characteristic, like a udovol'stvie in Russian. Thus, it can be reasonable argued that the Russian udovol'stvie and the Korean 즐거움 share many similar semantic properties. In brief summary, in both languages there exists two distinctive variants that show a privative opposition to express the emotional concept of joy.

This study examines fourth graders engaged in three concrete activities involving sampling from finite populations. The first included a survey of popular foods for school meals. The second had them take samples from a box containing white and black marbles to predict how many white and black marbles were in the box. The final activity required them to predict how many times the Korean letter '가' would appear in a Korean story book. The results show that the participants can experience and notice different ideas related to samples and sampling in different activities. In the first activity, they acknowledged that samples are useful for obtaining the information about populations. A population survey is difficult and is not overly useful. In the second activity, they recognized that samples cannot be identical to their population but that the information from a group of samples is similar to the information of the population. In the last activity, they devised some ideas about random sampling even though the ideas were immature.

캐나다의 통신시장 자유화 및 경쟁도입은 비교적 늦게 시작되었지만, 지금은 세계 어느 나라보다 경쟁적 환경이 각 분야에서 전개되고 있다. 이는 정부의 정책과 산업계의 활동이 경쟁 강화와 시장확대에 초점을 맞추고 있기 때문이다. 따라서, 캐나다 통신서비스 산업을 이해하기 위해서는 그 근간이 되는 규제측면에서의 이해가 전제되어야 하며, 본 고는 이런 맥락에서 규제기관의 주요 경쟁도입 결정과 그 후속조치로서의 경쟁환경 조성 제반조치 등을 중심으로 최근 10년간의 캐나다 통신서비스 산업 전반을 분석하였다.

The purpose of this study is to explore qualitatively what kind of coping strategy the Korean older adults use when they are depressed and why. Participants were users, older than 60, of an elderly welfare center in Seoul, and answers of 34 respondents who experienced depression were included in the analysis. The collected data were analyzed through content analysis. The results of the analysis showed that strategies to cope with depression used by participants were composed of 6 domains and 11 sub-domains: health behavior (medical approach / exercise and diet), family and social contact (social interaction / going out and going on a trip / communication with family), Religious activities (Religious activities), lifelong education (hobbies / educational activities), productive activities (labor), health risk behaviors (drinking and gambling / resignation). The depression coping strategies of the older adults and their characteristics are as follows. First, older adults used diverse problem-focused coping strategies to cope with depression. Second, older adults considered various coping strategies together and used them simultaneously. Third, the facility space for older adults functions as a shelter. Fourth, although there were cases where medical approach was used, the intention to reuse was very low. Through this study, the following suggestions were made to help older adults cope with depression more successfully. First, access to various coping strategies should be promoted. Second, more places where older adults can spend their time comfortably need to be provided. Third, resistance to mental health care should be resolved.

In this study, we explored the characteristics of instrumental genesis in high school students' scientific inquiries. Twenty-three 10th to 11th graders in a science research club participated in this study. The students in 6 groups autonomously planned and performed their own scientific inquiries for one semester. Their activities were videotaped and recorded. Semi-structured interviews were conducted. Material request papers and group worksheets were also collected for analysis. The results of the study suggested that students' practices were categorized as instrument genesis. When instrument genesis did not occur, the cases at the beginning of and during the practice were described respectively. Instrumental genesis was found to appear in three categories: instrumentation; instrumentation and instrumentalization; and instrumentalization. The characteristics and details of case represented in each category were described and discussed related to affordance as the results of the study. On the bases of the results, the implications for the reconsideration of the instruments in school science inquiries are discussed.

While growing interest about university education and quality enhancement, learner's scholastic achievement, learning process, various of learning activity work variable performance of university education. In this context, for quality enhancement of engineering education, it is necessary to pay attention not only learning achievement, educational conditions and environment, but also how students learn. The purpose of this study is checking learning activity in class of Engineering college students and proposing teaching and learning support for promoting learning activity in class. The result of this study is engineering college students were participate in highly only activity is called to professor, but self-directed learning engagements was less than. Activity of promoted thinking about task execution implemented frequently, but activity of critical thinking and applied everyday life were less than. In class students cooperated with colleague learner actively, they had sincere attitude about class. Based on these results, in order to promote learning activity in class, it is necessary sufficient teaching-learning support for learner's self-directed learning and enhancing thinking skills.

Nowadays there are presented various educational methods based on Constructivism which is regarded as newest epistemological paradigm about Knowledge and knowing, but none which is dramatically new. The educational methods proposed by the advocates of Constructivism are already put in practice by the teachers that are interested. Following this, we will interpret R. Skemp's theory about educational methods based on Constructivism. Here we will introduce various play activities for building number concepts.
