Song, Jin-Woong ; Kwon, Sung-Gi ;
Journal of The Korean Association For Science Education, volume 12, issue 1, 1992, Pages 1~9
This study investigated 15 Postgraduate students' conception toward the nature of science and the changes of those conceptions through the course called 'Philosophy of Science and Science Education', And another 8 postgrauate students who took the course called 'Mathematical Physics' were also investigated for comparison. A survey questionnaire involving 9 items was developed and administered before and after the course to both groups. Individual interviews with students taking 'Philosophy of Science and Science Education' were carried out in a small scale for obtaining additional information about their background knowledge. The results of this study showed that the students' traditional views of philosophy of science including the objective observation and the inductive method were reduced after the course, 'Philosophy of Science and Science Education'. On the other hand. views of modem philosophy of science including the theory-laden observation, the tentativeness of scientific knowledge and science as human activities became more popular. It was also found that their conceptions towards Science were different according to their previous knowledges on the philosophy of science and their majors.

Journal of The Korean Association For Science Education, volume 12, issue 1, 1992, Pages 11~21
This study tried to find out the effect to types of test items upon the momentum effect. The previous studies showed that the momentum effect is influenced by stduents' congnitive levels and the abstractness of test items. In this study focused on the types of test items The test items are divided into 4 different types of quantitative and qualitative, verbal and image. The result showed that qualitative items showed a longer momentum effect than quantitative ones. The image items and verbal items did not show significant difference in the duration of momentum effect. The interpretation of this would need a careful psychological analysis. Anyhow, this result reconfirmed the existence of the momentum effect and showed that the study on the momentum effect could be a Significant research paradigm.

Journal of The Korean Association For Science Education, volume 12, issue 1, 1992, Pages 23~33
For the purpose of identifying alternative conceptions in biology held by both elementary and secondary school students, an open-ended questionnaire in the six areas of biology was devised and administered to both 21 elementary school science teachers and 32 secondary biology teachers. Results have Shown that 65 and 183 items were introduced by elementary and secondary school teachers respectively Our findings will be useful to many researchers who have concerned about the issus of misconceptions in biology as well as many biology teachers who have had difficulties in biology teaching due to students' preconceptions.
The Comparative Study on the Effects of Three kinds of Teaching Model (Deductive, Inductive and Analogical Teaching Models) in Boiling Point Elevation
Kim, Do-Wook ;
Journal of The Korean Association For Science Education, volume 12, issue 1, 1992, Pages 35~46
The purpose of this study was to investigate the most effective teaching model in the study of boiling point elevation. The teaching models were classified into three group-deductive, inductive and analogical teaching models. Learning materials, based on three teaching models respectively, were applied to 11th grade students, and the effect of teaching models were investigated and analyzed. The average achievement score(4.24) of the group treated with the analogical teaching model was higher than those(3.06 respectively) of each group treated with inductive or deductive teaching model(p<0.001). Most students answered that the analogical teaching model was helpful and interesting one for the comprehension of scientific concept.

Jeong, Jin-Woo ;
Journal of The Korean Association For Science Education, volume 12, issue 1, 1992, Pages 47~60
The purpose of this study was to investigate studesnts' attitudes toward computers and science subject using CAI(Computer-Assisted Instruction) as an instructional strategy in the elementary school level of science and computer literacy course. The influence of CAI programs on learner's attitudes toward computers and science varied according to the variables of,(l)sex (2)experience by computer learning, (3)learner's attitudes toward computers and science. Eighty nine samples were divided into the two groups.One group(48 studesnts)which is in the experimental group took a science instruction using CAI programs and computer literacy course, another group which is in the control group took only a science instruction using CAI programs. Data were collected and compared the experimental group with the control group. The results indicate as follows:(l) studesnts took science instruction using the CAI programs appeared a positive attitudes toward science. (2) the science attitudes of science instruction using the CAI programs was more effective in the lower group than in the upper group. (3) computer literacy course produced the positive attitude toward computers regardless of the experience by computer learning. (4) students using CAI programs with computer literacy course were more effective than students using CAI program only. (5) science instruction using the CAI programs was not found a meaningful difference by sex.
An Analysis of the Nature of Scientific Inquiry and a Study on the Instructional Method for Promoting Inquiry Competence
Cho, Hee-Hyung ;
Journal of The Korean Association For Science Education, volume 12, issue 1, 1992, Pages 61~73
In response to epoch-making development in science and technology, the innovative curricular materials have been begun to develop since the late 1950s and early 1960s. However, the new inquiry-centered materials have failed to be successfully used in teaching/learning practices of science. Among the various reasons for the failure, the very nature of the inquiry approach has been identified as the most critical problem. Nevertheless, fostering inquiry faculties on the part of the students has been emphasized as one of the most important objectives of science instruction. Therefore this study was conducted for the purpose of developing a practical inquiry-oriented instructional method. In order to obtain this goal the nature of scientific inquiry was analyzed and the status quo of science education in which inquiry-oriented instructional strategies were applied was examined. The results of the study are described in this paper.

Journal of The Korean Association For Science Education, volume 12, issue 1, 1992, Pages 75~92
The purpose of this study was to point out the problems of the competency exam for college education, a new college entrance exam, and to suggest the improvement ideas for it For this purpose, the test items of science inquiry were taken from the first, the second and the third pilot studies of the competency exam for college education which National Institute of Educational Evaluation had done. These tests were administered to 1,223 students of the general high school(422 for the 1st 400 for the 2nd, and 401 for the 3rd test). Also, those students' and the high school science teacher's opinions about the tests and the new college entrance exam were surveyed. The evaluation objectives of those test items were analyzed and the test item analyses were done. The results were as follows; (1) The evaluation objective analysis showed that most of the test The purpose of this study was to point out the problems of the competency exam for college education, a new college entrance exam, and to suggest the improvement ideas for it For this purpose, the test items of science inquiry were taken from the first, the second and the third pilot studies of the competency exam for college education which National Institute of Educational Evaluation had done. These tests were administered to 1,223 students of the general high school(422 for the 1st, 400 for the 2nd, and 401 for the 3rd test). Also, those students' and the high school science teacher's opinions about the tests and the new college entrance exam were surveyed. The evaluation objectives of those test items were analyzed and the test item analyses were done. The results were as follows; (1) The evaluation objective analysis showed that most of the test items were constructed based on the evaluation framework which was composed of scientific inquiry thinking ability, science concept, and scientific inquiry context dimensions. But, those items were unevenly distributed into a few areas of the evaluation framework. (2) The boys had higher mean scores than the girls in all of the tests, but these differences were not statistically significant. The natural science course students had significantly higher mean than the humanities course students in all of the test:(1st, F=12.643, p=0.0004 ; 2nd, F=45.757, p=0.0001 ; 3rd, F=36.162, p=0.0001). A significant interaction of sex and course was found in only 1st test( F=11.352. p=0.0008). (3) Most students answered the test was difficult and they needed more time to finish it Also, they added they had to study in a different way from the traditional one in order to prepare the new college entrance exam. Science teachers answered that those evaluation objectives of the tests corresponded well with the educational objectives of high school science and that the tests were suitable as measuring instruments of the scientific thinking abilities. But they pointed out it would be very difficult for them to teach students for preparing the exam under the exsting educational conditions. To carry out successfully the competency exam for college education, the following improvements were suggested. (1) Good evaluation methodology should be developed. (2) In-service science teacher training models on evaluation should be put in force. (3) Effective teaching models and strategies should be developed.(4) The high school science curriculum should be revised.

The purposes of this study were; 1) to apply the network analysis to evaluation of students' laboratory reports, 2) to test the applicability of the systematic network analysis. For this purposes, 7th grade 88 students from 22 middle schools in Inchon city of Korea were selected and their laboratory reports were evaluated by a evaluation criterion network developed in this study. The evaluation criterion consisted of 4 categories and 10 subcategories. The results of this study suggested that the network analysis approach was suitable one for the evaluation of students' laboratory reports. This was supported by total score distribution, means/weight, Cronbach's
coefficient(0.70), and the subcategories' reliabilities. The resluts of the factor analysis indicated that the evaluation criterion network of this study had two factors.

Park, Yune-Bae ;
Journal of The Korean Association For Science Education, volume 12, issue 1, 1992, Pages 103~118
Quality control of science teachers seems to be one of the most important tasks to improve the quality of science education in Korea. The purposes of this study, as a survey, were to identify characteristics of good science teachers and to make an outline of preservice teacher education curriculum for cultivating the characteristics from inserivce secondary science teachers. A questionnaire was developed for this study and distributed to 176 inservice teachers. It had three parts: 1) characteristics of good science teachers, 2) weights of preservice curriclum areas, and 3) weights of college courses. The means and standard deviations of teachers' responses were calculated. To test the differences between teacher variables, t-tests were executed. The inservice teachers perceived that the junior-high school teacher's characteristics should be different from the senior-high school teacher's. Characteristics, such as enthusiasm toward teaching or students, subject knowledge, content selection and organizing skill, teaching techniques, and scientific worldview were ranked within top five of good science teacher's chracteristics. The teachers' perception about preservice curriculum were as follows: 1) present weight of liberal arts area should be reduced: 2) weight of content area for junior-high school teachers should be different from that for senior-high school teachers: 3) present weight of pedagogy area should be increased: 4) present weight of science education area should be increased: and 5) many courses in pedagogy and sciencd education areas need to be changed, Based on the data and disussion, a conceptual model for preservice teacher education curriculum was proposed.

Journal of The Korean Association For Science Education, volume 12, issue 1, 1992, Pages 119~127
The purpose of this study is to show the way of teaching the scietific talent in Japan. This study was conducted only by the printed matters. The results of the investigation are as follows: 1. Japan at present has neither systems nor laws for offical scientific talent education. 2. Japanese's scientific knowledge and way of rational thinking had been widespread among the general public by elementary education from one hundred ten years or so ago. 3. In addition, the instrument subjects such as foreign language and mathematics were well educated in the elementary and secondary school level and the preparatory courses of college. 4. Especially, the third and the first preparatory courses of a college(Daisan Koukou and Daiitchi Koukou) and Kyoto University have contributed greatly to the cultivation of liberal spirit in education, which turned out to be one of the essential elements for scientific talent education.
