  • Many elementary school students have misconception related to dissolution and solution. Moreover, they usually fail to apply the results of the experiments in their science classes to their everyday life, and also have low science achievement. Therefore, they are not interested in science, and sometimes some of them are even afraid of it. The purposes of this study is to investigate the effects of concept mapping activity on science achievement and attitude. In addition, this study also aims at presenting the teaching and learning method of utilizing concept maps in order to have the students form correct concepts. The subjects were classified into two groups one group is composed of thirty-seven students (experimental group) who were participated in concept mapping activity, and the other is composed of thirty-eight students (comparison group) who were participated in the traditional teaching method. The major findings of this study are as follows: First, the concept mapping activity has a positive effect on improving students' science achievement. Second, the classes using concept maps have a good influence on forming students' science attitude. Third, the concept mapping activity is more effective in improving science achievement of mid and low level students. In conclusion, the loaming by concept mapping activity positively influence students' science achievement and attitude.

  • Conceptual teaming has been one of the important issue in science education, and its theory and method has been interacted with the studies of philosophy of science, cognitive science, and cognitive psychology. The last two decades have witnessed a remarkable growth of the study on brain-style computation, i.e. connectionism. This study aimed to investigate the properties of the connectionist views of the concept and its implications in the conceptual learning of science. In connectionist views, a concept was represented as a pattern of activity distributed over many connected units, and a kind of network composed of many sub-concept units. And the 'distributed representation' had the features of the constructivity, the automatically generalization, and the tunability. On the base of these views, it was suggested that (ⅰ) 'Typically-Perceived-Situation', a kind of mental representation rising spontaneously in an individual mind when someone is thinking about any object, should be highlighted, and (ⅱ) the roles of the sub-concept units in formation of concept and the resolution of concept into the sub-concept units should be highlighted. Finally the meanings of these implications in conceptual teaming of science are discussed.

  • The purpose of this study is to look into self-concept and teaching anxiety of elementary school teachers about inquiry instruction in science class, and investigate correlations among them. For this study, the survey was carried out on 338 elementary school teachers, and the interview was conducted with 5 of them. The results of this study are as follows; Self-concept of elementary school teachers about inquiry instruction in science class was more positive than usual. And the teachers who were male, older and majored in science education showed more affirmative self-concept about inquiry instruction in science class. Teaching anxiety of elementary school teachers about inquiry instruction in science class was less than usual. And the teachers who were male, older and majored in science education showed less teaching anxiety about inquiry instruction in science class. The correlation of self-concept and teaching anxiety of elementary school teachers about inquiry instruction in science class was an negative interrelation. This presents that the teachers, who have more positive self-concept about inquiry instruction in science class, have less teaching anxiety than those who have more negative one. Consequently, teacher training and retraining programs should be developed and conducted by grasping teachers' self-concept and their anxiety, to reduce anxiety about inquiry instruction in science class.

  • This descriptive study was designed to find out the relation between self concept and ethical concept of nurses. The data were collected from 224 staff nurses in a tertiary hospital located in Suwon city during February 24 to March 7, 2001. Self concept was measured with questionnaire developed by chung (1965) and ethical concept was measured with the questionnaire developed by the researcher. The 5 point Likert scale questionnaire had 95 items. The results were summarized as follows: 1) The mean score of self concept was 3.11. The ethical concept were measured in 4 areas and mean scores were : accountability, 3,93; collaboration, 3.70; caring, 3.63; an advocacy, 3.15. So accountability was the area with the highest score in ethical concept. 2) Nurses' self concept was significantly related to ethical concept (collaboration, r=.34, p<.001; advocacy, r=.32, p<.001; caring, r=.28, p<.001; and responsibility, r=.23, p<.001). 3) The self concept was significant in age(F=3.28, p=.000) and the ethical concept was significant in age(F=15.88, p=.000), education level(t=2.16, p=0.03), career(F=5.16, p=.001) In conclusion, there was a significant relationship between self concept and ethical concept of nurses. High score in accountability may be related to high level of legal responsibility of nurses. This finding suggests that it is the length of nursing career is significantly related to both self-concept and ethical concept. Thus, it is important to improve self concept in order to improve ethical concept of nurses from early the beginning of their career.

  • The purpose of this study was to find some suggestions for reorganization of contents about particle concept of matter in Korean science curriculum. For the purpose of this study, authors analyzed features of Korean science curriculum and compared science curricula of Korea, USA, UK, Japan and Finland. From the result of this study, authors find some features and important suggestions about reorganization of contents about particle in science curriculum. First, the sequence of contents about particle concepts in 2009 Revised National Curriculum was similar to that in the 6th National Science Curriculum. And the feature of 2009 Revised National Curriculum showed the articulation of contents about particle concept. If contents about particle concept is increased in elementary science curriculum, the total articulation would be increased. Second, the presenting sequence of atomic structure-first and laws about atom-later should be changed to laws about atomic-first and atomic structure-later. This presenting sequence is grounded by science curricula of other countries, history of science and developmental psychology. And science curriculum of Korea was required specific extended concept statement like science curricula of USA or UK. Also, Korean science curriculum could benchmark Finnish science curriculum if we want to develop some integrated learning activities such as those in STS or STEAM program.

  • The purpose of this study is to examine the effects of utilizing concept maps in a rock-related unit. To do this, two groups composed of 73 sixth grade students engaged in this study. One group (experimental group) participated in utilizing concept maps in the unit, the other (control group) took part in traditional instruction in the same unit. The results of this study are as follows, after seventeen sessions: First, the achievement between the two groups showed significant difference. It indicates that utilizing concept maps as an instructional method is effective. Second, in the examination of the experimental group's attitudes toward concept maps, the students showed more affirmative responses on cognitive items than on affective items. Third, the students showed that they have difficulty in the method and the procedure of drawing up the concept maps. It indicates that the method and the procedure are sufficiently learned before instruction begins.

  • The purpose of this study was to apply a concept map to the first-year students of radiologic science and report its effects. The concept map is a visual representation of a major concept and related linking statements. Concept maps are useful tools for students to construct and organize content they have learned. The subjects of this study were first-year grade and at one university in Chungbuk, Korea. They were divided into active and passive participant groups in the class. And they were evaluated the educational effects such as satisfaction, fidelity, learning achievement, and interest before and after using the concept map. As a result, the passive participant group significantly increased the educational effect except for satisfaction, and the active participant group significantly increased the educational effect in all variables (p<0.05). These results showed that concept mapping, which induces first-year grade students to participate in class, could be helpful in radiologic education. It is expected to be used as basic data in various radiologic educational methodology studies in the future.
