  • This study was aimed to explore the effect of the physical science activity based on the constructivism on young children's scientific process skills and scientific attitudes, cognitive self-esteem. The subjects consisted of 20 five-years-old children of experimental group and 20 children of control group. Children of experimental group conducted the physical science activity based on the constructivism for total six weeks. As a result of study, children who experimental group showed significant result in the scientific process skill, scientific attitude, cognitive self-esteem. The educational implications of these indicate that we need to actively develop programs to increase scientific process skills and scientific attitude, cognition self-esteem of young children through teacher's education.

  • 20 preservice teachers at college level participated in this study and interacted with students at elementary and middle school levels during science camp offered by science center in Taiwan. Preservice teachers displayed moderate (above the average, 4 point out of 5) understandings about scientific literacy and scientific views in all aspects of the nature of science before the camp. Then, the researchers designed science camp programs which were expected to promote students' scientific literacy; scientific knowledge, inquiry skills for experimentation as well as for argumentation, affective domain such as the attitude toward science and the understandings about nature of science and the relationship among STS (Science-Technology-Society), all of which were embedded in the programs. Preservice teachers seemed to perceive scientific literacy pretty well (over 4 point) before the camp, however, preservice teachers' understandings about scientific literacy were not much scored (around 3 point, but still moderate scores of average) as expected after concrete inquiry activities. The reasons why this happened could be that preservice teachers were not trained to employ theory into the context to be more practical or the researchers did not develop camp program which included the aspect of scientific literacy successfully. The discussion and implication were made in teacher education in that preservice teachers must be prepared how to bridge theory into practice, and informal science education in that educators at science centers must be trained to be experts in providing the envisioned educational programs to meet the goal of science education, scientific literacy.

  • The Interdisciplinary-Multistrategic Science Education Program(IMSEP) is designed as an efficient program for the education of the gifted in science. An example of the contents is developed, which encompasses mathematics, physics, chemistry, astronomy, and biology. In the program, the complexity(interdisicplinarity) of scientific contents and instructional strategies used to deliver the scientific contents are designed to be correlated to each other in such a way that as the scientific contents gets more complex, the scientific skill to be taught by the instructional strategy becomes deeper. Through the careful balance between the scientific contents and the instructional strategies student's scientific knowledge and scientific skill will develop balanced and the effectiveness of science education will be maximized.

  • Currently, in Korea the scientific diving activity is being conducted without any legal basis, thus confusions arise in work coverage, equipment usage, and wage calculation etc. In this paper, introduction of scientific diver certification system is suggested to clear such confusions and to enhance the safety of scientific divers. Also the codes and regulations of foreign countries were introduced, and from the analysis of scientific diving tasks and applying skills, the hostility of the scientific diver's working environment as well as requirement of high level diving skills are explained. Finally the necessity of establishment of scientific diving regulation and introduction of diver certification system were emphasized and the promotion plan was discussed.

  • The latest researchs show that students have their own preconceptions about scientific phenomena or theory before they learn about it in school. The preconceptions exert a great influence on the teaching and learning science. The purpose of this study is to find out the effect of intelligence and attitude to science on elementary school students were sampled from 4th and 6th grade. Data were obtained by IQ test and the questionnaires on scientific conception and attitude toward science. The result was analyzed by t-test, Correlation and ANOVA in the statistical packages SPSS/PC+. The major findings of this study are as follows : 1. The mean score of scientific conception of elementary school students was 12.89. The mean score of attitude to science was 247.29. The mean score of intelligence was 109.93. 2. The correlation coefficient between scientific conception and intelligence (r=.5098)was relatively high(p<.001). The correlation coefficient between attitude to science and scientific conception(r=.2364) was low(p<.001). 3. Significant difference on science conception was found among grade levels(p<.001). Significant difference on science conception was not found between sex (p>.05). 4. The subjects were divided into 4 groups by intelligence and attitude toward science. These 4 groups show the significant difference (p<.01) in the scientific conception. The groups of high of high intelligence showed high scientific conception.

  • Despite the continuing emphasis on the importance of scientific inquiry, research studies have commented that authentic scientific inquiry is not implemented in school science classroom due to a lack of understanding of scientific inquiry by the teacher. The purpose of this study is to investigate understanding of scientific inquiry developed by beginning teachers through open-ended questionnaire and semi-structured interview. They voluntarily set up the goal of inquiry-based classes, planned inquiry-based classes, shared and reflected their teaching experience in professional learning community for more than a year. It appeared that participant teachers understood scientific inquiry as 'what scientists do', 'process how students do science' and 'science teaching methods.' All teacher participants described scientific inquiry as 'what scientists do', and understood 'the process of doing scientific investigation to solve problems related to natural phenomenon' and 'the process of constructing scientific knowledge using scientific practice.' Two participant teachers seemed to understand scientific inquiry as a 'teaching method' based on the understanding of the process how scientists or students do science. Participant teachers had a limited understanding of scientific inquiry that it is the same as laboratory works or hands-on activities prior to engaging the professional learning community, but they developed an understanding of scientific inquiry that there are various ways to conduct scientific inquiry after engaging in professional learning community.

  • This study was to evaluate the suitability of scientific questions as qualification examination for high school graduation by content validity and item response with three examinees and two preliminary examinees. As a result, scientific questions were concentrated on two units of six units of total, and application appeared to be lacking problem area by 8% compared to understanding and application. Examinees and preliminary examinees chose correct answers most by hap or guess, sometimes by experience or common sense, and the least by scientific concept. In addition, they could chose correct answers by hap or guess because there were words that implied the correct answer in questions and answers, or because they could compared and/or analyzed questions and answers. With these results, two proposals were suggested as follows; (1) scientific questions of qualification examination for high school graduation should measure basic scientific literacy. (2) specific criteria for science literacy in qualification examination for high school graduation should be set.

  • The aims of this study are to investigate how Kepler found a scientific problem for the retinal image theory and to investigate how Korean middle-school students respond when the same situation is applied to them. Kepler found the scientific problem in the eye vision through the critical analysis of contemporary theories of vision, based on his relevant knowledge of optics. When the same situation was applied to the Korean middle-school students, only a few students found the same scientific problem as Kepler. From the results, it is suggested that in developing creativity teaching materials, situations like Kepler's problem finding need to be included in programs.
