  • The aim of this qualitative case study is twofold: 1) to analyze how an eleventh-grader, Min-Seon, conceive and represent a pattern of change between two varying quantities in a quadratic functional situation, and 2) further to help her form a concept of 'derivative' as a tool to express the relationship with employing a concept of 'rate of change.' The result indicates that Min-Seon was able to construct graphs of piecewise functions that take average rates of change as range of the functions, and managed to conjecture the derivative of a quadratic function, $y=x^2$. In conclusion, we argue that covariational approach could not only facilitate students' construction of an initial function concept, but also support their understanding of the concept of 'derivative.'

  • This students ideas in science are diverse and unique It is realized that children's preconceptions and misconceptions established before lessoning hgve a crucial in fluence on the following education. so it is meaningful to analyse the children's concept of temperature for the better teaching strategy in this study. This survey of the Elementary school children's concept is designed for the subtopics of temperature as the relation between heat and temperature, He relation between volume(size) and temperature, the temperature of change of state on water, the temperature of substances in the condition of thermal equilibrium. Using Clinical method, this research was executed to 306 children at elementary school. The network method or the analyse of questionnaires were used to analyse the children's response. Findings of this survey are as follow. Students are already familiar with such concept as this increase of temperature by geating, but they think every substance is not the case. Many students appears to believe that the temperature of an object(substance) is related to its size(vloume) Qualitative tasks are difficult than qualitative ones. This trend appear highly in the low grade students. Don't know the temperature of change of state on water and it's stability They think that the temperature is determined by the heating time(period) and the temperature of heating source. Students think, in general that temperature of substance in the condition of thermal equilibrium is different.

  • The effects of three teaching models were compared in this research. One of those is concept change model, another is concept change model based on students learning motivations, the other is traditional teaching method based on science textbooks. The subjects of this research were the 8th grade students of Korean middle school. They were divided into three groups, and tested learning motivations. All of the three groups improved their learning motivations and concept understanding by the classes. Especially, the group of concept change model based on students learning motivations represented most effective improvement of learning motivations. The concept change teaching model and concept change teaching model based on students learning motivations are more effective in concept understanding than traditional teaching method based on textbooks. The students who have high learning motivations improved their concept understanding by the classes of concept change model based on students learning motivations. The students who have low learning motivations improved their learning motivations by the classes of concept change model based on students learning motivations also.

  • Although many studies have investigated the effectiveness of concept mapping and the learning cycle, in Korea none have explored the effectiveness of concept mapping and the learning cycle combined. This study explored the effectiveness of concept mapping, the learning cycle, and a combination of concept mapping/learning cycle(CL) in high school biology class. Students' science achievement, the science related attitudes and scientific inquiry ability was measured. The results indicated that concept mapping, the learning cycle, and CL treatment were significantly different from the traditional one in science achievement(p< .05). However, the three treatments were not significantly different from each other. No significant difference exists among different learnings in high and average-ability students. But, concept mapping was the most effective in low-ability students. For the students' scientific inquiry ability, CL and learning cycle were more effective than concept mapping and traditional learning. No significant difference exists among different learnings in high-ability students. CL and learning cycle were more effective than concept mapping and traditional learning in average and low-ability students. For the students' science related attitudes, concept mapping, the learning cycle, and CL were more effective than the traditional learning. But, there was no significant difference among these three groups.

  • The purpose of this study is to analyze the effectiveness of secondary school SMART education. In order to achieve this, the paper separated the high school which implements the smart education for the high school and the high school which did not apply the smart education concept, then figuring out the answer about what school is more effective, the influence of the smart education concept on the students' emotions and academic achievement. This paper analyzed the effectiveness of SMART Education between Hansol high school in SeJong city and Jungang high school in Gwachen city by using 'schoolinfo (www.schoolinfor.go.kr) SMART education.' This study first presented the SMART Education's concept and characteristics through reviewing some literature, and then categorized the characteristics by using the items included academic achievement and emotional effect. These items consist of the 'students academic scores' for the academic achievement, 'the number of students dropped out' and 'the damage rate of school violence' for the emotional items. The conclusion of this study is that Hansol high school indicates lower school violence rate than Gwachen high schools with the two school's violence rate decreasing. Moreover, students' score of Hansol high school is higher than high schools in Gwachen city. The SMART education school budget structure is 'Common type', which requires a lot of investment to 'Basic education activities', 'educational activities support', 'School general operating expenses' among education budget items.

  • Failure is an important part of engineering practice. Engineers utilize all of their competences and resources in order for their products or processes to meet the initial intention and purpose, and not to fail. However, the technological products sometimes end up with failure. The failure, in many cases, is related to non-technological factors or systems, not just limited to technological factors. Moreover, the evaluation of failure is performed by a variety of agents, including consumers, civic groups, government as well as professional groups. Thus, this study raises an issue that the existing concept of failure, which focuses on the operation of function, is not sufficient enough to properly cover the success or failure of technology required by the modern society. In the recent trends of engineering, new concepts and methods have been developed by expanding the traditional concept or introducing a new perspective of failure, so that engineering failure can be better understood in the mutual relationship between technology and society. This research attempts to suggest a methodology of how the failure of engineering can be utilized and properly combined in the major education, design education and engineering ethics education. Also, it aims to contribute to the quality improvement of engineering education to train engineers who can lead the society with responsibility as well as professional competence.

  • Physicians should be able to address health-related issues of patients and populations from a multidimensional perspective. Therefore, medical schools have a social responsibility to develop and implement curricula that enable trainees to acquire the competencies needed to improve all aspects of patient care and healthcare delivery. This study explored the concept of health systems science concept as the third pillar of medical education (the other two are basic science and clinical medicine) in the Korean context, as well as related educational needs. The theoretical foundation of health systems science is the biopsychosocial conceptual model, which emphasizes the biological, psychological, and social factors surrounding patients. We concluded that the three domains (core functional, foundational, linking) and 12 subcategories of health systems science proposed by the Association of American Medical Colleges could be applied to Korean medical education. Health systems science education must be emphasized to solve the various healthcare problems facing Korea today and to train physicians to provide medical services in line with society's needs. Introducing a health systems science curriculum will be challenging in the Korean medical environment, which has traditionally emphasized basic science and clinical medical education. Health systems science education should begin in the basic medical education phase, where physicians' professional identity is formed, and continue through graduate medical education. It is essential to understand related educational needs, develop curricular content, conduct faculty development programs, and provide financial resources for the development of an integrated curriculum.
