  • The purpose of this study was to examine how the career maturity of high school students was affected directly or indirectly by psychological separation from their mothers and through the mediation of self-concept. The subjects in this study were 496 juniors from regular high school in the city of Daegu, who included 243 boys and 253 girls. The measurements of this study were a career-maturity inventory, psychological separation inventory (PSI), and self-concept scale. The major findings of this study were as follows: First, career maturity had significantly positive correlation to conflictual independence from mothers for them. Second, as for the influence of psychological separation, and self-concept on career maturity, three variables, including competence self-concept, home self-concept, attitudinal independence from mothers, classroom self-concept, had significantly explanation of career maturity. Third, as a result of making a path analysis of the impact of psychological separation from mothers on career maturity through the medium of self-concept, conflictual independence gave a direct impact only, and its indirect effect was insignificant. The attitudinal independence showed both direct and indirect influences, for mothers had a significantly indirect impact only.

  • A concept is a building block of a theory. The purpose of a concept analysis is to clarify the critical attributes of a concept and identify its real meaning, particularly if the concept is not understood in a clear and accurate manner. This study was conducted to analyze the concept of support, which has been adopted from another discipline and unclearly used in nursing science. For concept analysis of this study, Walker and Avant's method was used. Support is defined as a domain with emotional. informational. material and evaluative aspects. Critical attributes of the concept of support included (1) an experience of support between a support provider and a client, (2) communication, (3) a relationship of mutual interchange of emotional, informational, material, evaluative support, and (4) intention, Cases related to the concept of support included model cases and appendix cases (against. boundary, and related). Antecedents of support were anxiety, depression, and loss of self-esteem, and consequences of support were comfort, increase of self-esteem, and trust. Based on these results, a nursing intervention that can provide a better quality of life for the prevention of diseases, health management, and health promotion may be developed in the future.

  • 이 연구에서는 이미 해결한 단일개념으로만 구성된 복합개념상황에서 학생들의 문제해결력과 정신용량의 관계를 알아보았다. 과학적 개념이나 원리 하나만 알면 풀 수 있는 문제를 단일개념상황으로 정의하였고 단일개념상황을 2개 이상 결합하여 만든 문제를 복합개념상황으로 정의하였다. 청주시 소재 일반계 고등학교 2학년 학생 152명을 대상으로 정신용량에는 유의미한 차이가 나타나지 않았다. 그러나 이미 해결한 단일개념상황들의 결합으로 만들어 전 복합개념상황의 문제해결에 있어서는 정신용량이 작은 집단에서만 실패한 학생들이 나타났으며 문제해결에 실패한 학생들의 정신용량이 문제해결에 성공한 학생들의 정신용량보다 낮았다. 이러한 연구 결과 단일개념상황은 해결할 수 있으면서 이와 관련된 복합개념상황의 해결에 실패한 이유의 하나를 문제해결자의 정신용량이 작기 때문이라고 볼 수 있다.

  • Knowledge is composed through the interaction between the concept structure already held by students and their experience, and learning can be said to be the active process of solving the cognitive conflict caused by this interaction. Therefore, this study consists in showing the effective learning method and finding out the elements which the teacher has to own, through examining several forms of pre-conception or mis-conception of the inertia, the force-equilibrium, the action and reaction, the heat, and the electric current, and then finding out their solution and studying student's change in science concepts. For this study, the types of concept on the five above-mentioned materials which students have were examined through the concept-classifying question paper, and the classes to which the class mode for the change of concepts applied, were practised in each different classroom by each different instructor - a professor, a scientist, a teacher, and two students, respectively. And the effect of the teaching strategy based on these classes, and each different instructor' influence on the change of concept in students. were examined. The result of my study is as follows; 1. Students have various types of pre-conception which are different from science concept, and these types of pre-conception tend to last even after learning in class. 2. The thoughts on the correct science concept of the high school third-grade students who learned the physics in the traditional teaching method, and the second grade students who don't learn the physics yet, were nearly equal those of the second grade students by receiving the physics class through the cognitive conflict course were greatly changed especially that students showed the distinct change on mechanics and electric current. 3. Students didn't show the remarkable change of the science concept on the five materials in the four kinds of experimental classes by each different instructor but in the part of mechanics, there was the distinct change between the class by professor and those by the students. This was due to the difference of the authority and the attitude of the concept demonstrator. 1) The authority, the kind attitude, and the responsibility of the expert played an important role in the correct concept-formation of mechanics part - especially in the case of the mis-conception caused by the intuitive belief. 2) In the class by instructor with the democratic teaching method, the change of concept took place more easily, because in his class students could discuss the subject freely, so that they might experience the thought course to give them the confidence on the science concept.

  • The purposes of this study were grasping the degree of students' understanding for course contents through the concept mapping strategy as meaningful learning in science and measuring the effect for change of conception and changing the misconception. The results of the study were as follows: 1. Before the lesson, only 10.7% of students had scientific conception of molecular motion. Other students had various kinds of misconceptions. 2. The extent of concept formation after lesson through the using concept mapping strategy was tested. As a result, compared with the controlled group, the experimental group showed higher extent of sound concept formation (statistical significance level 0.05). 3. The differences between the experimental group and the control group were analyzed into quantitative and qualitative points of view. The results of the comparison showed that the maps of the students were well configured in the categories of the relationship, the hierarchy and the examples; while students showed lower abilities in the category of the cross-links. 4. The student's attitudes to ward concept mapping was positive. Most of the students answered that teaching strategy of concept mapping benefits them in meaningful learning outcomes.

  • The purpose of this study is to examine the effects of background knowledge on problem solving. To achieve this aim, I proposed the model which shows problem solving process centering around background knowledge, conducted the lessons concerning the concept 'weightlessness' on pre-service elementary teachers, and then classified the pre-service elementary teachers into several groups by the difference of the results presented in the process of solving the problems on weightlessness. And I examined qualitatively the effects of background knowledge on problem solving through the interview with 11 volunteers. On the cause of the failing the problem solving, the failure of acquiring or activating the background knowledge related to the learning concept was most frequently, secondly the use of the background knowledge unrelated to the learning concept, and thirdly the failure of understanding the teaming concept. To acquire or activate the background knowledge related to the teaming concept was more difficult than to understand the new teaming concept, and the cases that use the background knowledge unrelated to the learning concept failed to solve problem. The result of interview, all interviewee understood the learning concept correctly, but all of them who fail to acquire or activate the background knowledge related to the learning concept, or use the background knowledge unrelated to the learning concept, could not solve the problem.
