This study was to analyse the understanding of the concepts of science based on the 6th graders' levels of logical thinking in elementary schools. To achieve the goal of this study, logical thinking test was given to 108 6th graders of elementary school and 32 students were interviewed. The result of this study was as follows. First, 61.1% of students were in concrete operational period in their logical thinking, 27.8% were in their transitional period, and 11.1% were in their formal operational period. By using Flow-Map, 32 students were analyzed and their levels of logical thinking was significantly associated with their understanding of concept. Students' flexibility of cognitive structure was significantly associated with logical thinking and the levels of understanding concepts as well. However, misconception didn't show significant association with levels of logical thinking. Second, the characters of understanding of scientific concept by their levels of logical thinking was that as you get higher levels of logical thinking, their cognitive structure to understand concept was more systemized, in order and more logical. The result of this study suggested the followings in science experiment class. First, 6th graders of elementary schools had various levels of logical thinking and that affected to their understanding of scientific concepts. Therefore, lesson planning and class should be done by reflecting their different levels of logical thinking. Second, since they had different levels of logical thinking, various teaching methods should be utilized to make students understand scientific concepts more systematically.

Although ‘to understand mathematics’ is an important educational purpose, most student do not have a relational understanding of the basic concept of mathematics but have a instrumental understanding. This paper will investigate the possibility of using computers for enhancing relational understanding. In the ‘Qualitative case study’, three students who are in the first grade at E-High school took part in 7 activities during four weeks, and were later interviewed and engaged in informal discussion and were observed. This is the result of this study. 1. The three students were passive participants in mathematics problem solving situation at school. Therefore, student B just applied formulas which she had memorized, and student C would forgot the formulas occasionally. These common students needed to participate actively in doing mathematics. 2. The activities utilized two software healing with connection between graphs and function, giving the students the opportunity to plan, practice, and test by themselves. As a result, they understood the mathematical formulas and rules more deeply through their own trial and error, and then they gained thinking abilities necessary for doing mathematics. In addition, the activities boosted their confidence. 3. The understanding type of students was slightly different. Student A who received a high score, understood the most relationally, but student B who received a very high score, understood instrumentally and so couldn't app1y her knowledge to solving problems related to function concept. Student C who received a middle score lacked knowledge of mathematics but thought more creatively. The result is that students need an opportunity to think rotationally regardless of score. Therefore, this study concludes that using computer software will provide a positive effect for relational understanding in loaming function concept.

The purpose of this study is to identify students' alternative frameworks about tide concept, to investigate some characters of them and students' understanding types with increasing grade in secondary school earth science course. The objective questionnaire method was used, and the subjects of this study are 528 students selected randomly in secondary school. The results are as follow. 1) Thirteen alternative frameworks about tide concept, related to the phase change of the moon and the motion of the earth are identified. 2) The alternative frameworks needed mechanical and causal reasoning have the trend reinforced or sophisticated with increasing the grade. And alternative frameworks needed phenomenal and mechanical, phenomenal and causal reasoning are changed little but ones needed phenomenal, variative and basic reasoning change scientifically. The rates of the alternative frameworks needed definitional, empirical, phenomenal reasoning decrease at the learning grade of that concept but increase after that grade. 3) Middle school students have the definitional, phenomenal, empirical and qualitative understanding types but high school students have the causal, analytic, quantitative and mechanical ones on tide concept.

Two groups of students, who are the students in the natural science course of high school in Korea, learned the equation of figure in space (point, line, plane) to understand more effectively with two different textbooks. One group was taught with the textbook used now in most high schools and the other group was taught with the textbooks systematized by associating old concept with new concept. The results are as follows : 1) We need understand the basic concept of vector plainly and flexibly to apply it to the solution of problems. 2) It helps students understand new concepts how we should establish the concept about point, line and plane in space by applying the concept about those on XY plane, 3) It is very effective in understanding the new knowledge system more easily to analyze the existent concepts and to arrange them systematically for efficient understanding of new concepts. 4) The texts which consist of contents organized by basic concepts improve students' learning ability.

Purpose: This study was done to analyze and clarify the concept of empathy in nursing. Methods: Using the concept analysis framework of Walker & Avant 68 articles about empathy were selected for this study. Results: Defining attributes of empathy included recognizing others' perspective and thought, understanding others' emotion, and communicating with them. The antecedents of empathy included contact with patients, respect and trust for patients, a certain level of cognitive ability, and communication skills. Consequences of empathy were increasing patient self-understanding, self-awareness as a therapeutic subject and improving quality of nursing. The concept was clarified through presentation of model, borderline, related, and contrary cases. Conclusion: The results of this study are meaningful in that the concept and attributes of empathy are explored in the area of nursing. Also, based on results of this study, development of standardized tools to measure patient-perceived empathy and measure the three attributes of empathy is recommended as well as the development of educational programs to enhance empathy.

구분구적법에 대한 이해는 리만합의 극한으로 정의되는 정적분에 대한 이해의 기초가 된다. 그러나 선행연구는 구분구적법과 리만합의 극한으로서 정적분 개념에 대한 학생들의 이해에 여러 가지 한계가 있음을 지적하였다. 이 연구에서는 선행연구 분석을 통해 구분구적법의 개념 지도에 있어 크게 두 가지 어려움이 있음을 확인하였으며, 이를 개선하는데 기여할 만한 교수학적 시사점을 각각 기술하였다. 나아가 미국, 영국, 일본 교과서에 비추어 우리나라 교과서에서만 고유하게 다루어지는 정적분과 무한급수의 관계가 리만합의 극한이라는 정적분의 개념 지도에 있어 필수적인 내용 요소인지를 반성적으로 검토하였다.

이 연구에서는 고등학생을 대상으로 정적분 개념의 이해와 관련되는 특징을 살펴보기 위해 선행연구와 국내외 교과서에서 다루고 있는 정적분의 개념 정의를 알아보았다. 이를 토대로 지필형 검사지를 개발하여 고등학교 2학년 학생 108명을 대상으로 검사를 실시한 다음 그 결과를 선행연구와 교과서 분석 결과에 비추어 기술하였다. 이 연구에서 학생들은 리만합의 극한이라는 정적분의 정의에 대한 최소 아이디어조차도 거의 기억해내지 못하였다. 또한 적지 않은 학생들이 정적분 개념이 넓이와 부정적분보다 무한급수와 관련된다고 생각하였다. 리만합의 극한으로 정적분을 정의하는 방식과 정적분을 무한급수와 관련시키는 맥락에 대한 반성적인 검토가 필요하다.
