  • This study examined factors influencing college science learning from the perspectives of college students and high school science teachers. Using a survey created based on focus group interviews, college science majors and high school science teachers rated various factors of high school learning that positively influenced college science learning. Findings suggested that the perceptions differed by college major: the physics major students considered math proficiency and logical thinking skills as the important factors; chemistry major students and biology major students considered English proficiency and basic scientific knowledge as the most important factors. Both college students and science teachers emphasized basic science knowledge and math proficiency. However, differences between the two groups were also found in that the students perceived more need to learn about experimentation than the teachers whereas the teachers had a priority in increasing advanced science content.

  • Although over - 600 students in Incheon has been participated in the gifted education programs under the colleges and Office of Education Department every year, it is reported that the number of teachers have insufficient teaching abilities in primary, advanced, and after-advanced gifted classes. The Gifted Education Research Institute in Incheon University introduced R&E activities for the improvement of teachers' abilities in science research and student guiding. Professors in science department conducted the R & E activities to select the research thesis. The professors and the guidance teachers decided the directions of the research, and the guidance teachers who learned from the professors taught 3-5 students to practice the research. Five professor-teacher-student research teams in math, physics, chemistry and biology conducted the research after school and during the vacation for 7 months. The results of the research were submitted to the journals of research activities and the result papers were presented to the seminar. On this research, the possibilities and the difficulties of the R&E activities based of the journals of research activities, oral presentation and the research results reports were analyzed with a purpose of improving the professionalism of the science gifted teachers. Although the professors proposed many difficulties or problems about the R&E activities, the teachers reported that the R & E activities he1ped them to improve their research activities and student guiding techniques. The teachers acquired more knowledge on the principles of the science related areas than before. Moreover, they thought it was very meaningful experience in using the science related instruments, guiding the students' research and writing the research reports. The students also gave the positive responses with the increased interests in new science studies and with the experience of learning the way of research.

  • Many science teachers can be able to miswrite the vocabularies for seven kinds of experimental tool names on blackboard of secondary school in Korean language. The diagnosis test for the miswriting possibility was carried out by science teachers in secondary school. We questioned "How can you write each of Korean vocabulary for seven experimental tools?" to each of one hundred and fourty science teachers in three class of physics, chemistry, and biology during inservice training course of Gyeongsang National University on August in 1997. First of all, for the investigation we showed the real things of seven tools to the teachers and they wrote each vocabulary for each tool name on blackboard in English. In addition we explained the general use of each tool name. And then the teachers answered the vocabularies of them on one written paper. The miswriting results for seven tools were as follows. There appeared various miswriting vocabularies for each tool name. For examples, meas cylinder was miswritten two kinds of Korean name and the miswriting ratio of 4%, Mortar & pestle was miswritten four kinds of name and the ratio of 12%, Beaker & desiccator were miswritten one kind of name and the ratio of 51% and 36%, separately. Separatory funnel & spuit were miswritten two kinds of name and the ratio of 54% and 58%, separately. Schale was miswritten four kinds of name and the ratio of 51%. We might conclude that the cause of miswriting vocabularies for the tool name could be due to the original miswriting in Korean-English or English-Korean dictionaries as well as the seience teachers by themselves.

  • The purpose of this study was to find out the difficulties of teaching the chapter on 'ight', experience of learning, teaching methods, and thinking types of 10 science teachers of the master's course in chemistry education. Discussion course for abduction thinking was carried out during 12 hours after the interview. Data were collected from individual interviews of 4 teachers among the 10 subjects and from the reports of the science teachers after the discussion course. From the data, it was found that most of the science teachers had suffered difficulty in teaching the chapter on light before the discussion course. Most of them had tried to teach drawing the path of light, but there was little teaching effect. Their teaching methods were similar to the method of what they had learned. During the course, the teachers recognized they could not see the path of light directly, and it needed inferring from image. From the abduction thinking, the teachers recognized the meaning of image and gained concrete methods in teaching students.

  • High school common science is introduced by the sixth national curriculum. It consists of physics, chemistry, biology and earth science like the secondary school science. In this paper, textbooks are analyzed by the science teachers and the status of the present teaching and learning methods is reported. The detailed results are as follows; 1. Almost high school teachers choose textbook that included little the STS material. More than two teachers are teaching the high school common science and when they are chosen, they are independent with their major. 2. According to the national curriculum, they evaluated the textbooks as it is below the middle level. This evaluations are not dependent on teachers' comparement and textbook's class except the several matters based on STS (science-technology-society). 3. The teacher teaching the high school common science thought that teaching the textbook in school is worse than analysizing it. they must have emphasised on learning of inquire method than system of knowledge, introduction to material connected with real life and STS in the high school common science.

  • The purpose of this study was to investigate characteristics of interaction in mentoring conversations and to examine how the interaction features change as mentor teachers have more mentoring experiences. Participants of this study were three mentor who have over 17 years' teaching experience and six beginning science teachers. For this study, one-to-one mentoring dialogue recordings and transcripts were collected and the dialogues were analyzed by utilizing an analytical framework of interaction. the result of analyzing characteristics of mentors' interaction shows that mentors used simple questions and support the most when they started mentoring conversation. the change of characteristics of mentor's interactions indicates three mentors tended to use more thought-provoking questions in the $2^{nd}$ year mentoring than in the $1^{st}$ year and as a result of it mentee's reflection and reflective practices were increased. Through mentors' interview, the mentors could have the opportunity to reflect their own mentoring and this means mentors' self reflection was provoked by means of the mentoring program.

  • The purpose of this study is to examine implications of pre-service science teacher training by analyzing science field integration and connection between learning content presented in 'Integrated Science' for high school students based on the 2015 revised science curriculum, and in pre-service science learning materials (textbooks) of the college of education. For this study, the 2015 revised 'Integrated Science' curriculum and 11 types of pre-service science teachers' learning materials related to physics, chemistry, biological science, and earth science were selected. The results were as follows. Most of the learning content presented in the 2015 revised 'Integrated Science' curriculum had integrated two or more science fields. Also, almost all learning content presented in the 2015 revised 'Integrated Science' curriculum were included in pre-service science teachers' education content, with educational content for chemistry introduced at the highest rate. The textbooks for pre-service science teachers had the most learning contents of 'Energy and Environment' domain of 'Integrated Science' for high school students. Accordingly, these results suggest that 'integrated science materials' should be developed for proper the curriculum implementation. Also, training courses for science teachers responsible for 'Integrated Science' are required. Furthermore, a revised curriculum for the college of education and a method to link with certification examinations for secondary school teachers are needed.

  • The purpose of this study was to investigate explanations of science textbooks and science teachers' conceptions related to freezing point depression phenomenon. Seven kinds of middle school science textbooks and five kinds of high school chemistryII textbooks were analyzed for the purpose. The teachers' conceptions were searched by a questionnaire developed in this study. The subjects were 146 science teachers. The explanation types of science textbooks were divided into two; 'Description of the phenomenon' and 'Vapor pressure lowering'. The explanations in most of middle school science textbooks and high school chemistryII textbooks belong to 'Description of the phenomenon' and there was no explanation of the reason. The graphs related to depression of freezing point were diverse, too. Most of the science teachers also did not have scientific conception. The percentage of the teachers who thought that the cause of freezing point depression was blocking of solute in solution was high. But the teacher could not find meaningful relation the 'Blocking of solute' explanation represented for elevation of boiling point with depression of freezing point. It is insisted that entropy concept is need to explain depression of freezing point phenomenon in this study.

  • In this study, we investigated pre-service secondary chemistry teachers' use of teacher's guide in planning lessons. Eleven pre-service teachers at a college of education in Seoul participated in this study. Textbooks and teacher's guide books including various teaching materials were provided. Pre-service teachers used teacher's guide while they planned two lessons, which were a lecture and an instruction using science teaching model. A semi-structured interview was conducted. All of the teaching-learning materials and interviews were analyzed. The analyses of the results revealed that most pre-service teachers followed each lesson presented in teacher's guide, but they did not consider the structure of the whole unit and science curriculum. There were some cases that the exemplary lesson planning in teacher's guide helped them to select science teaching model. They modified the questions of textbook activity in planning their lecture. On the other hand, they modified the activity to fit each stage of the model in planning their instruction using science teaching models. Most pre-service teachers constructed their own worksheets by applying the materials of the teacher's guide. They recognized the components of assessment by considering exemplary lesson planning from the teacher's guide, and created questions by modifying the content of textbooks and teacher's guide books including various teaching materials. However, the questions which they made were limited in context of knowledge. They evaluated that introductory questions were not of interest to students, and modified or added new materials. Educational implications of these findings are discussed.

  • The purpose of this study is to draw implication for scientific inquiry study by investigating level of understanding and actual state regarding the elementary school teachers' scientific inquiry. The survey was conducted toward 42 elementary school teachers who work at the D city by using questionnaire of Views About Scientific Inquiry. Actual state of understanding of scientific inquiry was investigated by categorized the responses to the level of understanding of the eight aspects of scientific inquiry in three levels (informed, mixed, naive) based on analysis criteria. And analyze whether the characteristic of the subjects affect to level of understanding about aspect of scientific inquiry. As a result of the analysis, the two aspects among the eights aspects of scientific inquiry; 'Inquiry procedures are guided by the question asked' and 'Research conclusions must be consistent with the data collected' were appeared to have high rates of informed level of understanding. In the remaining six perspectives, most of elementary school teachers had naive and mixed level of understanding, so informed level of understanding took a relatively low proportion. It implies that elementary school teachers who teach inquiry in the field have limit to understand about scientific inquiry. These results indicated that experiences that have taught students and science related training courses that open sofar have a little influence to increase comprehension about scientific inquiry. Therefore, it is required to reinforce the teachers' understanding about scientific inquiry and to formulate different form of plan unlike existing way of teaching for teaching scientific inquiry.
