The National Competency Standard (NCS) is being implemented on the basis of a college of higher education. The college offers intensive education by organizing three areas of knowledge, skills and attitudes so that students can perform their full capacity at the same time as graduating in industrial field. Health Department at the College has been training for a variety of medical personnel, including medical technician regions. Especially, the medical technician and medical sector must be licensed to work in the medical field. Therefore, passing the national examination license is a prerequisite for employment. In this study, the health law scores of the third grade students (about 200 students) of the radiology department of D College were analyzed at weekly intervals. The weekly score acquisition can be predict the pattern of student class achievement of individual students. Furthermore, these results can predict the possibility of passing the radiation license examination for individual students.

The purpose of this study is to explore needs and the direction for the development of localization data in the geological field of elementary school. Many studies show that geology-related learning is highly effective in the form of direct learning, and It is reported that this learning has a positive effect on students' scientific attitudes. As such, the first-hand experience of the geological learning is outdoor geology learning and is the basis and core of the development of localization materials. However, the analysis of this study shows that the development of outdoor geology learning site is mainly conducted in some regions. In addition, considering that geological sites are distributed evenly throughout Korea, it is necessary to actively develop geological-related localization materials to learn elementary school geology-related units. In addition, some areas where outdoor geological study grounds were developed are composed only of learning places and no specific learning materials have been developed. In this regard, not only geological researchers but also field teachers working in the area need much effort. Development of localization material in the geological field needs to be developed at the level of material presented in the geology unit of the textbook. And in the actual class, it is desirable to use the textbook data and the developed localization data at the same time. In addition, the development of the outdoor geology field should be developed in consideration of the pre-experience-post activities so that learners can have various geological experiences.

The Natural Science High School is specialized in vocational education or training related to natural sciences such as biology or chemistry. Therefore, natural science high school students are expected to possess a high level of science learning motivation. This study aims to explore natural science high school students' level and structure of science learning motivation by comparing students in general high school. One hundred ninety three students from a natural science high school and 208 from a general high school participated in this study. We administered a questionnaire that consisted of seven science motivation components: 1) career motivation; 2) science grade motivation; 3) understanding the relevance of scientific knowledge; 4) need for learning science; 5) self-determination; 6) self-efficacy; and 7) attitudes toward science class. We employed independent t-test, path analysis, bivariate correlation, and stepwise multiple-regression for the statistical analyses. Our findings illustrated that the natural science high school students' levels on all seven variables were significantly lower than the general high school students.' The path analysis illustrated that career motivation and science grade motivation had relatively stronger influence on self-determination and self-efficacy in the natural science high school student sample than in the general high student sample. The explanatory powers of four independent variables (career motivation, science grade motivation, understanding the relevance of scientific knowledge, and need for learning science) predicting self-determination and self-efficacy were 30% higher in the natural science high school student sample than in the general science high student sample. These results suggested that natural science high school students' science learning motivation may be easier to change by extrinsic motivations such as career and science grade motivation.

In this study, we developed an analogy-generating strategy and applied this to a 7th grade science-gifted class. The types of analogies they generated, verbal interactions and analogy-generating patterns, and perceptions of five groups on the analogy-generating strategy were examined. The analyses of the results revealed that there was a higher proportion of the elaborated analogies in terms of quality generated by science-gifted students individually in the analogy-generating strategy than in general analogy-generating activity. After having small group activities, most small groups generated the elaborated analogies. The frequencies and percentages of verbal interactions of each sub-stage were found to be slightly different. Analogy-generating patterns in small groups were categorized into three types; selecting in-depth source, selecting inclusive source, and selecting surficial source. The elaborating patterns of mapping between a target concept and analogies were different among the types. Science-gifted students positively perceived in terms of its values and attitudes toward the analogy-generating strategy, and they responded that the analogy-generating strategy was helpful in generating more elaborated analogies and fostering creative thinking. Therefore the analogy-generating strategy is expected to generate positive impact on the creativity of science-gifted students.

The purpose of this study is to examine the effects of PBL (Problem-based Learning) strategy applied to the "Inorganic Chemistry Laboratory" class. Especially, the changes in 'self-directed learning ability' and 'attitudes toward science' of undergraduate students were examined. In addition, perception on PBL problem and the PBL classes were investigated. The results of this study were as follows: First, after the course, 'self-directed learning ability' and 'attitude toward science' of students were significantly improved (p < .05). There were significant improvements in every sub-categories except 'self-confidence as a learner' for 'self directed learning ability' and every sub-categories except 'usefulness of science' for 'attitude toward science'. Second, the students expressed that PBL strategy provided opportunities to learn self-directively and responsibly, but the process of defining the problem was difficult. Finally on the survey toward PBL strategy, the students responded that PBL problems were authentic and helpful to learn problem solving ability. In conclusion, PBL laboratory course is effective for developing self-directed learning ability and positive attitude toward science.

The purpose of this study is to design internet CEDA (Cross Examination Debate Association) debating model for the internet-based learning. Comparing to open discussion model that is widely spreaded in regular classes, the CEDA model can enhance learner's thinking skills, logicality, analytic skills, and judgement ability. In the first study, 196 students were provided the specific CEDA model guideline and participated debate activities through the internet. The results of the students' debate were analyzed based on the evaluation criteria. The results showed that the students' evaluation scores were high overall. They favored the CEDA model over the open discussion model, and showed positive attitudes and perceptions on the CEDA internet debate activity. In the second study, another 200 students were participated in two different tutor supporting CEDA debating groups, one is advanced tutor strategy group and the other is general tutor strategy group. The results showed that the advanced tutor supporting group had significantly high scores on the cross examination and providing evidence on debating. This study finally suggests the CEDA internet model for general use. In conclusion, this study also suggests the next steps to elaborate the CEDA internet model not oかy for the university settings, but also for general school settings. The user manuals should be developed to assist instructors, students, and tutors to guide better debate activities through the internet CEDA class. Also further research should be conducted to provide various debate models and applications for the variety of learning environments, and so the schools to use the CEDA model more widely in the internet classes.
