The purpose of this study was to analyze physics problem solving processes according to students' cognitive style in the area of 'Force and Motion' at high school level. Students who have already learned t e area of 'Force and Motion' during the first semester of the 10th grade have taken physics test and cognitive style test to choose students who have basic knowledge of physics and reflective or impulsive style. Four students who got over 19 points in the cognitive style test were selected as reflective students, and another four students who got below 12 points were selected as impulsive students. After explaining the purpose and procedure of this study, think-aloud method was introduced to the students, and the students practiced it. After that, the students solved three quantitative and qualitative problems each. Then, the questionnaire on the belief system on physics and physics problem solving and prerequisite knowledge test were also administered. By recording the students' problem solving processes, protocol was made and analyzed. After solving the problems, the students expressed their confidence, intimacy, and preference on each problem by the five point Likert scale. Impulsive students tended to succeed in solving more problems, less intimate, and more spontaneous and positive in seeking alternative solution when confronted with unacquainted problems. On the other hand, reflective students used more time in executing the problems even without planning, and used more time in solving problems and verification. Whether making effective plan or not was important rather than how much time they used in the planning step. In addition, repeating steps were more likely shown to impulsive students; they tended to be attached to their first idea.

This study aimed to investigate the role of scientific empathy in influencing students' productive disciplinary engagement in scientific activities and analyze the key factors of scientific empathy that manifest during this process. Twelve fifth-grade students were divided into three subgroups based on their general empathic abilities. Lessons promoting productive disciplinary engagement, integrating design thinking processes, were conducted. Subgroup discourse analysis during idea generation and prototype stages, two of five problem-solving steps, enabled observation of scientific empathy and practice aspects. The results showed that applying scientific empathy effectively through design thinking facilitated students' productive disciplinary engagement in science. In the idea generation stage, we observed an initial increase followed by a decrease in scientific empathy and practice utterances, while during the prototyping stage, utterance frequency increased, particularly in the later part. However, subgroups with lower empathic abilities displayed decreased discourse frequency in scientific empathy and practice during the prototype stage due to a lack of collaborative communication. Across all empathic ability levels, the students articulated all five key factors of scientific empathy through their utterances in situations involving productive science engagement. In the high empathic ability subgroup, empathic understanding and concern were emphasized, whereas in the low empathic ability subgroup, sensitivity, scientific imagination, and situational interest, factors of empathizing with the research object, were prominent. These results indicate that experiences of scientific empathy with research objects, beyond general empathetic abilities, serve as a distinct and crucial factor in stimulating diverse participation and sustaining students' productive engagement in scientific activities during science classes. By suggesting the potential multidimensional impact of scientific empathy on productive disciplinary engagement, this study contributes to discussions on the theoretical structure and stability of scientific empathy in science education.

Because of the gap between the cognitive levels of the students and the curricular materials for the students to understand, the secondary school students feel science difficult and they get to avoid science as they go up to the higher grade. So it is absolutely needed to take the active measures to improve the cognitive development of the students through some special programs stimulating their cognitive process. This study investigated the effects of thinking science activity program devised for cognitive acceleration of the students. After implementing thinking science program to 181 7th grade students, the effectiveness of this program was examined through the analysis of covariance of both experimental and control groups. The result of the study showed that the cognitive level of the students in experiment group dealt with thinking science program was more accelerated than that of the students in control group who were just taught regular science curriculum. Especially, the effect was clear to the students in stages 1 and 2B. It was also found that the percentage of the students who promoted from concrete operational stage to formal operational stage was higher in experimental group than in control group. The results of the study implied that cognitive acceleration of the students might be possible through the specially designed materials such as thinking science program.

As the spatial analysis paradigm was established in the discipline during the 1960s, the regional geography became regrded as a nonscientific enterprise. However, school geography has remained an old fashioned regional paradigm. Since then, regional framework which characterized geography curricula in education has been attacked and replaced by more scientific and systematic content. But recently, globalization and localization has rapidly transformed the everyday life of ordinary people. This social change requires regional awareness in school. The purpose of this study is to find relevant learning theories for geography in deucation and to suggest principles of constructing content for regional geography. We must transform the logic of regional concepts into educational content with reference to the learning process. We must examine various propositions for the leaming process. According to the Atomic view of knowledge, the learning process is cumulative, but this can't be applied to sophisticated knowledge. In the Organic view, the learning process is regarded as gradual differentiation. But the learning process is reciprocal, and socially constructed. Applied to geography in education, this view regard "meaningful learning" as social interaction between student's private geographies and content based on public (or academic) geographies.

This study investigates the effectiveness of computer programming with KODU on problem-solving abilities of elementary school students. Diverse tools were developed for novice programmers to become more easy and comfort in learning a computer programming. Among them, KODU has focused on facilitating the programming of various multimedia applications to create games, animations and music videos etc. It is expected that KODU will help elementary school students to improve their problem-solving abilities through creating their own games, animation, and music etc. In this paper, we developed the educational program using KODU for teaching the elementary school students. The developed programming course was offered at the 5th grade students of a elementary school in Seoul and a total of 27 elementary school students were participated in our programming courses. Most of the students stated that the course was interesting, and their problem-solving ablilities were improved after the course from March 2014 through May 2014.

The purpose of this study was to find out the learner's characteristics of students of Korea Science Academy by comparing general high school students and science high school students to Korea Science Academy students in terms of scientific attitude, learning styles, preferred teaching style, and learning environment, and to find out the differences of the learner's characteristics by gnender and school number, and to establish teaching strategies based on the findings. First, scientific attitude level of Korea Science Academy students was similar with science high school students and was high level comparing with general high students. Second, for learning style, the students of Korea Science Academy had many independent, collaborative and participatory types, Third, for the prefered science teaching style, the students of Korea Science Academy had high demands for diversification and thinking at higher levels girl students had open-mindedness and cooperation and voluntariness of higher level in scientific attitude, had more independent types in leraning style, and had higher preference of teacher's support, subject convergence and permissive atmosphere than boy students. there were no difference of student's characteristics and preferences by school number. Based on the findings, we proposed 4 teaching strategies.

The purpose of this study is to explore characteristics and limitations of a novice teachers's responsive teaching practice, who framed argumentation productively. One novice teacher and two eighth-grade classes participated in this study. Two of the small student groups with active teacher intervention were selected as focus groups. Students engaged in argumentation activity where they built an argument for hearing if the eardrum was torn. We recorded the class and interviews with the teacher and the students, which were transcribed for use in the analysis of the teacher's responsive teaching practices and epistemological, positional framing. We discovered that teacher thought that he should position himself as a facilitator to encourage students to present ideas clearly and to reach consensus. His framing was consistent in responsive teaching practices. Positioning himself as a facilitator, after he framed the discussion as idea sharing discussion by eliciting and probing students' idea, he framed the discussion as argumentative discussion by taking up students' idea and pointing out disagreement between them. As a result, members of small group 1 engaged in argumentative discussion and reached consensus. However, the teacher's productive framing did not guarantee students' productive argumentation practice. In small group 2, he did not elicit and probe students' ideas successfully. As a result, members of small group 2 did not engaged in argumentative discussions. He responded limitedly to the lack of students' conceptions because of lack of understanding about learners. Also, he mainly attended to students' reasoning, and not to students' framing about argumentation because he considered argumentation only as a tool for conceptual learning. The result of this study will contribute to the establishment of responsive teaching in science classrooms.

The present study applied cognitive continuum theory to university environment in order to demonstrate that students' cognitive modes move along the continuum to be adaptive to the certain situation. This study also compared students' cognitive modes and the generally required modes in the university. The results showed that the students used corresponding cognitive modes to each subject even though they had different cognitive styles in general. It means that the students are adaptive to various tasks. And, the comparisons of the students' cognitive modes with the require4 modes in the university showed that the university tended to induce the students to use analytical cognitive modes. Therefore, the university faculty should be aware that they usually induce the analytical modes, and that they need to use various kinds of cognitive modes in order for the students to have adaptability and flexibility. However, the study did not demonstrate that the students would perform better when they fitted their cognitive modes into each subject.

We analyze the admission test problems used in 1998 at the Science Education Center for Gifted Youth at Kyungpook National University (SECGY, KNU). The test consists of two parts, an evaluation of the scientific thinking skills and an evaluation of the achievement for Mathematics and Sciences, the former of which includes evaluations of scientific process skills and logical thinking skills. The problems for the test of scientific thinking skills were developed and standardized by the Korea Education Development Center, while those of the achievement for Mathematics and Sciences were made at SECGY. We calculate the indices of the difficulty and discrimination for each problem to determine whether or not the test is appropriate to apply for selecting number of gifted students among the recommended students from 389 middle schools in Taegu-city and Kyungsang-pook-do Province. We find that both indices of most problems for the test of scientific thinking skills were out range of the appropriate level and. moreover, even those problems which fall into the appropriate range showed very low efficiencies for distractors. We, thus, conclude that the problems of the test of scientific thinking skills are inappropriate to use as a test for admission to SECGY. On the other hand, the problems of the achievement test showed extreme results; the Mathematics problems appeared to be too difficult, whereas the Physics problems appeared too easy. However, overall scores showed a normal distribution, indicating that those problems played crucial role in selecting gifted students. We finally propose several suggestions in developing the test problems and in selecting students at the SECGY.
