The purpose of this study was to explore the process of scientific thinking as it is revealed through the cases of constructive play for young children. For this purpose, the researcher observed and interviewed six four-year-olds in the Jaemi Class while recording them with a camcorder during a free choice activity class in the morning from April 23 to June 25, 2012. The observations were analyzed in chronological order according to the changes of theories and structure as presented by the children themselves. The process of scientific thinking in constructive play for young children can be divided into presentation of naive theories, the abandonment of naive theories according to repetitive experiences and the discovery of inconsistency, the representation of alternative theories, and the abandonment of alternative theories according to repetitive experiences and the discovery of contradictions. On the basis of the results, constructive play has proved to serve a valuable educational function by inducing scientific thinking processes in children. On the basis of this finding, the researcher suggests the need to provide appropriate educational support to teachers.

National park, as a natural park, has a dual purpose, to promote both protection and enjoyment. The educational activities of the national park can be partly understood as one of the appropriate means to balance its double purposes. This study provides a review of environmental education in the US National Parks according to social transition. Taking historical perspective and case studies, environmental education has played roles in helping the balance between preservation and enjoyment. Since the environmental movement, environmental education goals, particularly understanding the natural processes observable at national parks, has become more a part of the interpretation and education missions of the parks. Also non-governmental and non-profit partners have played important educational-based roles in support of both the National Parks Service and environmental education goals. The two different models also differ in the public's perception of them. Federal employees are resented in some rural areas in the U.S., but the general population automatically attributes authority, friendliness, and national-interestedness to NPS Rangers. This may in turn limit how strongly such staff could serve as strong advocates for the environment. On the other hand, the non-profit may be seen by some as strongly liberally biased and associated with urban wealth. It is also not as universally recognized as the NPS. It can, however, go far to develop new partnerships and undertake public relations. Non-profits vary greatly in quality, also affecting public perception.

While the affective aspects are emphasized in the current mathematics curriculum in Korea, it is just indicated a superficial degree. Therefore in this study, based on consideration for internal representational system theories, a dynamic viewpoints of self-system processes, socio-constructivist perspectives, and motivation theories, we discuss the meaning of affective competency, the motive of mathematics learning, mathematical identity of students, social environments and affective experiences, then we suggest an affective frame in mathematical learning. Hereby, we suggest what should be considered in affect instructions and the alternative goal of mathematical education in affective aspects.

In the present study, we analyze four seventh grade students' recognition of geometric properties and the following justification processes while their adopting different construction approaches in GSP(Geometer's Sketchpad). As the students recognized dependency and level-1 invariants by dragging activities, they determined their own construction approaches. Two students, who preferred robust construction, immediately recognized the path of a draggable point and provided step-1 justification. The other students attempted soft construction followed by their recognition of level-2 invariants and the path, and came to step-2 justification.

The purpose of this study is developing the manifestation process model of group creativity among mathematically gifted students. Therefore, I designed the manifestation process model of group creativity by researching the existing literatures on group creativity and mathematical creativity. The manifestation process model of group creativity was applied to mathematically gifted students' class. By analyzing students' response, the manifestation process model of group creativity was improved and concretized. In conclusion, the process of a combination of contributions was concretized and the major variables on group creativity such as a diversity, conflict, emotionally supportive environment and social comparison were verified. In addition, some reflective processes was discovered from a case study.

This paper is to make strides toward an enriched understanding of mathematics teacher learning and professional development. Different theoretical frameworks in understanding mathematics teacher learning are reviewed, followed by a discussion of the relationships of knowledge and teaching practice. This paper then analyses contemporary conceptions about effective professional development and, in particular, deals with teacher learning in inquiry communities. This paper introduces a research project describing transition processes from teacher- centered mathematics classroom culture to student-centered culture and analyzing teacher learning in communities and its concomitant change in teaching practice. On the basis of the emerging problems in doing the project, this paper finally addresses some crucial issues on teacher learning and professional development, including the management of an inquiry community, the description of teaching practice from the researcher's perspective, and the analysis of teacher learning in communities.

A new way of teaching on the Internet can be called Web Based Instruction (WBI). WBI goes far above and beyond teaching in the school. It will have an impact on overall educational activity that will dramatically change many existing educational processes and persuade most teachers to change their conventional teaching methods. The main purposes of this research were to make a comparative study of academic achievement between expository lecture and web-based instruction, and to identify the difference in academic achievement of learning tasks in pre- and post- experiments of WBI. The conclusions of this study were as follows. First. there are no differences in academic achievement between expository lecture and teacher- directed web based instruction. Second, there are no differences in academic achievement between expository lecture and teacher-assisted web based instruction. Third, there is difference in academic achievement between teacher-assisted web based instruction and teacher-directed web based instruction. Fourth, there are no differences in academic achievement of reading tasks in pre- or post- experiments of teacher-directed web based instruction. On the basis of the research results and discussion, we finally present a Web-Application-Model (WAM) to encourage the usage of Internet as a useful teaching channel.

This paper aims to propose the educational concept and design model of a Smart Board Game appropriate for lower elementary grade students. The Smart Board Game refers to a hybrid, or 'convergent', game format based on the offline format of the conventional board game augmented through the use of smart devices. The substantive aspects of this game format utilize the procedural deduction and problem-solving skills applicable in storytelling methodologies and games, in order to generate and propose contents ideal for the educational environment. The development of the Smart Board Game is conducted through the following stages. First, the study analyzes a number of Smart Board Games currently popular in Korea and abroad, based on identification of the key components and processes of the board game format. The subsequent review of the science curriculum for lower elementary grades aims to determine the aspects conducive for application to Smart Board Games. Lastly, the theoretical framework outlined through the previous stages is used as the basis for the proposal of a detailed model of contents for the smart board game concept.
