The purpose of this study was to identify elementary school students' alternative conceptual types of the movement of the moon and to find out how these types change when confronted with cognitive conflict situations. To find out alternative conceptual types, 206 sixth graders were sampled, and to investigate how the alternative conceptual types were changed by cognitive conflict situations, and 30 students were systematically resampled by alternative conceptual types. Data were collected through the pre- and post-test instruments, including five items that were used for testing the students' alternative conceptual types and changes after conflict situations. After the pre-test, students were instructed to determine the change of the alternative preconceptions using conflict situations. We found that a majority of students had various kinds of alternative preconceptions formed from their early years of elementary school. The cognitive conflict situations were effective for the conceptual change of the movement of the moon. Specifically, in all groups, the subjects' understanding of "the movement of the early evening crescent moon" changed scientifically.

The present study aims to develop animation module-based teaching-learning materials for a unit of middle school 3rd grade science, which contains the movement of the solar system, through the utilization of various forms of multimedia elements. The developed materials consist of 12 in total flash animation modules covering ‘movement of the Earth,’ ‘movement of the Moon,’ movement of the Planets,‘ etc. To analyze the student responses to the science classes to which the developed animation modules were to be applied, the researcher selected for subjects two third-grade classes that were made up of 60 students and later divided for an experimental group and a control group in a middle school located in Jeonju. The experimental group was treated with the animation module-based lessons developed in the present study while the control group was taught in the traditional teacher-centered ways. Tests for the science-related attitudes of the two groups were administered and the results showed that the mean score of the experimental group was significantly higher than the mean score of the control group (p<0.05) in the categories of ‘interest’ and ‘scientific attitude’. It was thus believed that the animation module-based teaching has a positive effect on the categories of ‘interest’ and ‘scientific attitude’. To assess the qualitative dimension of the developed materials, the researcher subjected them to the utilization of the 30 local science teachers and afterwards a survey was done with the 8 crucial items taken from the WBI evaluation test developed by Multimedia Education Support Center in 1998. The result was broadly positive in terms of lesson design and from a technological point of view.

The objective of this study was to develop a scientific approach for investigating Korean dance in detail, and to examine the intense expressions and various movements, which are based on Danjeon breathing. For the purpose, we analyzed the movement changes and distribution of forces resulting from the switch in movement between exhalation and inhalation while bending, which is the most basic movement in Korean dance. The following conclusions were drawn from this study. In Korean dance, bending with breathing involves less back-and-forth-movement and more up-and-down movement, as compared to bending without breathing; this indicates greater body stability and a wider range of movements while bending with breathing. In addition, less time is required for bending with breathing at the point of switching from exhalation to inhalation, and it involves less movement of the supporting leg; thus, vending with breathing involves faster switching from bending movements to extending movements. While bending, the raised leg goes through a less smooth curve while breathing, which indicates stronger movement of the toes. Bending with breathing requires a greater braking force than bending without breathing, and the vertical force, generated by switching from exhalation to inhalation, is transferred to extending movements using the ground load. The results of this study can be potentially employed to investigate the expressions used in Korean dance on th basis of its principle of forces. Korean dance has evolved into various creative forms, and basic analytical studies of these diverse forms and related breathing methods re required in the future.

Objective : The purpose of this study was to give the basic data for the cutting movement with the various angels on the poly urethane. Method : Ten healthy men voluntarily participated in this study. A three-dimensional motion analysis system (VICON) and force plates were used to analyze the movements of the joints for the lower extremities. For the statistical analysis the IBM SPSS 21.0 was used to perform repeated measured ANOVA and post-hoc comparison result was used to perform the Scheffe and the level of significance was set up at ${\alpha}=.05$. Results : There were significant differences for the time required for the increasing angles of the cutting movement(p<.05). In addition, there were significant differences for the maximum dorsiflexion, plantarflexion of ankle joint, maximum flexion of knee joint and hip joint with the increasing the angles of cutting movement(p<.05). Also, there were significant differences for the maximum adduction and abduction angle of the hip joint with the increasing of the angles of cutting movement. There was signigicant difference for the resultant utilized coefficient of friction(RuCOF) for the increasing angles of cutting movement(p<.05). Conclusion : There was a pattern to increase the coefficient friction with the angle of cutting direction. Also, it would be possible to use the poly urethane for the outdoor floor with the results of this study.

Movement is everything in life and music is with our whole lives. Based on movement and sound, art has developed and reflected the times with close ties to technology and is creating new cultural content in the digital age. The absence of experts and research institutes with academic knowledge and experience in various fields compared to the frequency with which music and body movements are interwoven in the intermedia art and education of convergence is a real problem. Introducing the Rhythmik that studied the most basic principles of music and exercise through the precedent of foreign universities, we raise the need to introduce music physiology, musicians' Medicine and music performance science, the areas we studied together. It presents a new direction in the convergence era and education in pioneering research areas in which the only "I myself" systematically recognizes the movement to become the subject through physiology and medicine and scientifically moves and expresses music as a medium.

The purpose of this study is to investigate various mathematics education improvement or reform movements of Western Europe countries (United Kingdom, Germany, etc.) and the United States of America, to see the effects of those movements on Korean mathematics education circle, and to find a direction of Korean mathematics curriculum design. The third Korean mathematics curriculum was most affected by the new mathematics movement of the United States of America. This movement was emphasizing abstract structure, logical rigorousness and discovery learning of mathematics, which was fired from late fifties. Korean mathematics education circle imported the new mathematics early seventies from USA, but serious problems had been found at that time in USA. This study has pointed out that new math oriented Korean mathematics curriculum was not proper and the new mathematics itself was disastrous for most Korean students' learning. The study also points out that they hurried too much introducing the new mathematics and publishing new mathematics oriented textbooks but they had not sufficient teacher training programs. In our future mathematics curriculum reform, we have to remember such a historical lesson.

In accordance with the rapid industrialization in Korea, there have been remarkable changes in the health environment. The major changes are ; the change of disease structure, the aging of population structure, the diversification of health needs and the increase of health care costs. Because most of health problems stems from the environment, national health policy should be conducted according to the environmental changes. It is necessary for the voluntary organizations as well as the government ones to plan and participate the national health promotion movement on a national level so as to make the people form the attitude that health promotion is better than cure. Also, it is desirable that national health promotion movement be implemented gradually especially by four steps, 1) preparation step; 2) enlightenment step: 3) implementation step: 4) evaluation step.

With an emphasis on scientific literary, science education has again became closer to the interests and needs of people and sometimes expands its scope beyond the boundaries of school and the curriculum. Science educators often claim that its historical roots can be traced back to the movements of General Science and Science and Citizenship during the 1920s-40s. This study attempts to re-interpret the historical meanings of the Mechanics' Institute Movement (MIM) from the perspectives of science education. In doing so, this study first introduces the process of the emergence of MIM with a focus on its founder, George Birkbeck, and the Andersonian Institute where evening science classes began to be open to skilled workers. Then the overview of MIM is described, with examples drawn from the London Mechanics' Institute and the Manchester Mechanics' Institute. In discussing science teaching of MIM, the details taken from various mechanics' institutions are examined in terms of why, what, and how to teach sciences. This study argues that the MIM was a unique social phenomenon in which science could respond to the needs of skilled workers through education, providing science learning opportunities which were otherwise unavailable and that the MIM shared many similarities with current practice of science education, moving towards a wider career perspectives, cross-subject, community-based, and informed citizenship.
