Cho, Hee-Hyung ; Ko, Young-Ja ;
Journal of The Korean Association For Science Education, volume 28, issue 4, 2008, Pages 269~281
In Korea, the criteria for the requirements of a secondary school science teacher's certificate are based entirely on the subjects and/or areas as prescribed in laws for the teacher's licensure examination. However, the criteria do not account for the specific competencies or qualities that a good science teacher should possess. The objective of the research was to explore and suggest the three lists of the image of an ideal science teacher, science teacher's role and science teacher's competency that might be used to establish the criteria for science teachers' certificate and the curricular content for science teacher education in Korea. In order to achieve this objective, the study used such research methods as literature analysis, status survey in combination with on-line workshop, in-depth interview, and professional consultation. The participants in the research comprised of a group of 258 students (186 middle school students and 72 high school students) and 13 in-service science teachers (8 middle school science teachers, 5 high school science teachers) for questionnaire survey and on-line workshop, and 4 science teachers for in-depth interview. The list of the image of ideal science teacher, science teacher's role, science teacher's competency contains 44, 32, and 75 statements, respectively. Based on the results of the research, this paper suggested that the criteria for the Korean secondary school science teacher's certificate requirements be selected and organized in consideration of the teachers' competencies rather than the courses and/or subject areas. It is also implied in the paper that further research over a period of time is necessary for using the competencies for curricular contents and/or science teacher's certificate standards.

The Research and Education (R&E) program was a year-long, apprenticeship and research-based program that was guided by mentors who are scientists or science teachers. The objective of the R&E program was to help scientifically gifted students in Korea Science Academy (KSA) and Science High Schools (SHS) to enhance abilities in creative thinking, scientific inquiry, problem solving, positive attitude towards scientists, and promoting cooperative research and interests in science and technology. In this study, the impact of the R&E program on the goals of 182 gifted college students in KAIST was evaluated using Likert-type items and multiple-choice method approach that provided a more comprehensive evaluation of the program's impact on science attitudes, creative thinking, scientific inquiry, and interests in science and technology. The results indicated a positive impact on cooperative research, gaining knowledge on the research topic, attitude towards scientists, interest in science and technology, scientific inquiry, and creative thinking in that order. There were rather remarkable and meaningful differences in science inquiry (p<.05), and scientific knowledge (p<.01), between the two groups of KAIST freshmen who came from SHS and KSA in 2006. Implications for science apprenticeship or a research-based mentorship program and their respective evaluations are also discussed.

The purpose of this study was to investigate explanations of high school chemistry II textbooks and the diversity of chemistry major teachers' thinking types related to dilute solution properties for finding the sources of students' difficulties. Eight kinds of textbooks were analyzed, and the teachers' thoughts were searched by a questionnaire developed for inquiring teachers' preference of explanation types. We analyzed teachers' responses from individual interviews after the questionnaire to discern their deeper thoughts. From the results, it was found that the explanations of the textbooks were not clear enough to have scientific conceptions. The figures and explanations of the textbooks do not match either. It was also found that chemistry major teachers' thoughts were not solid when they suffered cognitive confliction by different situation with their thoughts.

Circular motion has been one of the most difficult concepts for students to understand. To facilitate for students to form scientific mental models about circular motion, this study developed 4M learning cycle teaching model based on the integrated mental model theory and strategies. For this study, fifty-three eleventh graders at a technical high school in Inchon were taught for 3 class hours. We conducted tests of basic physics concept and mental model of circular motion before, after, and two months after instruction. In results, we found that there were statistically significant improvement in the test of basic physics concept and mental model related with circular motion after instruction. Especially, this teaching model affected learning effectiveness of Correctness and Coherence of mental model.

During the past two decades or so, science (or scientific or scientific & technological) culture has become one of the main themes not only of policy makers but also of science educators. Although, the idea of science culture has been taken as a desirable goal, there is little agreement about what it means and how to measure it. Particularly in Korea, there has been a rapid growth of science culture projects and programs, either by governmental or non-governmental, but with little systemic monitoring and evaluation for its practice. The purpose of this study is, thus, to explore a model of measuring science culture and develop a comprehensive indicator system for it. We reviewed many literatures on definitions of science culture and the surveys for related terms, particularly, of recent national and international surveys (e.g. US Science and Engineering Indicators, Eurobarometer, Japanese Science and Technology Indicators). Based on this review, a model for science culture is proposed and then used to define the Science Culture Indicators (SCI). This model encompasses two dimensions(i.e. individual and social), which are further divided into two aspects (i.e. potential and practice). Each dimension is expected to represent citizen literacy of and national infrastructure of science culture respectively. Each category in this
matrix is further divided into several sub-categories. The discussion concerning how the model and the indicators can be used to check the states of science culture at social as well as individual levels will be given with some concrete examples, such as indicators particularly related to science education.

The aim of this study was to compare the effectiveness of microcomputer-based laboratory (MBL) with the traditional laboratory experiment on science classes in middle school. MBL tools were developed and applied for five experiment subjects chosen from middle school science textbook for MBL experiment classes, while usual experiment methods suggested in the textbook were used in traditional experiment classes. In order to evaluate the effects of MBL experiment class, achievement, graphic ability, science process skills, affective aspect related to science were tested before and after applying the MBL experiment. The result revealed that MBL experiment class was more effective than traditional experiment class in improving student's science achievement, science process skills, and graphic ability. The result also indicated that there was a significant difference between experiment and control group with regards to the effect on affective aspect related to science. From the above result, we can find the positive implication of applicability of MBL experiment as a new experiment tool at the early stage of introduction in a real context.

This study investigated the mapping errors induced in learning the concept of reaction rate with analogies, and compared these mapping errors by the analogy presentation types. Tenth graders (N=418) at a high school were assigned to the four groups by the target concepts and the analogy presentation types. The target concepts were 'concentration and reaction rate' and 'temperature and reaction rate'. In presenting analogy, the verbal and the verbal/pictorial analogs were used. After the students learned one of the analogs, a mapping test was administered. From the analysis, eight types of mapping errors were identified: overmapping, artificial mapping, failure to map, rash mapping, mismapping, mapping of a superficial feature, retention of a base feature, and impossible mapping. According to the analogy presentation types and the features of the target concepts, there were some differences in the frequencies of mapping errors. Educational implications of these findings are discussed.

The purpose of this study was to investigate the effects of interview with a scientist and engineer on service performance assessment on science career orientation and image of scientists. Science track students in the 11th grade carried out the interviews and made powerpoint presentations. After the students' presentation in the chemistry class, the teacher made comments on the contents of the interviews. Students gave presentation in each class for a year. Before starting this assessment, students took science career orientation questionnaire and DAST (draw-a-scientist-test). These two tests were conducted again at the end of the year. The results of this study showed that there was no significant difference between pre- and post-test score for the science career orientation. However, a significant difference was observed in the 'preference for science learning' category. These results showed that the career decision of a high school student has already been fixed rigidly. On the other hand, there was a significant difference (p < 0.01) between pre- and post-test on the image of scientists. This demonstrated that the stereotypic image for a scientist was reduced by the interview performance assessment and that, students came to have an affirmative perception of scientists on service.
