  • This study was to understand the components that influence preservice secondary teachers' conceptions about 'seasonal changes' We selected 74 university science education students among whom 23 were in the second, 23 in the third, and 28 in the fourth year. The data collected from the paper-pencil test and individual interview with students. The results of this study show that the students had considerable apparent alternative conceptions, and that the 'distance theory' had most important effects on their alternative conceptions. It can be said that preservice secondary teachers' initial models of the seasonal change have their origin in their belief sets (specific theory) related to 'seasonal change', on the basis of which they can interpret their observations and cultural information with the constraints of a naive frame-work of physics. The structures and possible sources of their alternative conceptions for overcoming these alternative conceptions were also discussed. Implications for preservice science teacher education related to the results were discussed.

  • This study investigated the current science teaching evaluation system implemented in schools and directions for improving teaching evaluation using literature review, survey, and teacher interview. The first part of this paper analyzed the types, roles, and major issues of the current science teaching evaluation. In-service teachers argued that the current teaching evaluation system was discredited because of the bureaucratic procedures of teacher performance review, showcase classrooms, teachers' views on classroom as their own personal space, low ratio of teaching component in the current teacher evaluation, untrained evaluators, and the absence of professional teaching standards. The second part of the paper investigated the need for a formative teaching assessment, an ideal type of teaching assessment, and the role of participants in the teaching evaluation processes. The way forward, therefore, is to start not at the level of the administrative superstructure but at the level of teachers who will assume responsibility for developing standards of practice as the basis for evaluating their own work and improving their own professional learning to provide quality assurance.

  • The purpose of the study was to establish a new view of textbook which may contribute to the abolishment of the instruction mainly based on the only textbook and to the promotion of creativities of students. We first reviewed science textbooks and related teaching-learning materials of foreign countries with emphasis on the relationship among textbook and teaching-learning materials and practical use of them. In western countries the roles of traditional textbook has been changed. That is, various kinds of materials such as reading book, work-book, worksheet, experimental guidebook, filmstrips are used to raise effect of instruction besides of traditional type of textbook. Secondary, we identified the problems related to the science textbook-view of textbook, textbook contents, practical use of textbook-through opinion survey administered to principals akd teachers of elementary schools. The results of the survey are as follows; Concerning the view of textbook, most teachers did not recognize textbook as an absolute materials. They thought that textbook contents could be taught reorganized according to their judgements. On the contrary, teachers responded to the question of whether or not they follow contents of textbook as they are presented in it were approximately 30%. Further, more than 75% of them have seldom used instructional materials except textbooks. In order to revise the problems of our present textbook as stated above, a new view of textbook should be established. We, above all, established 4 basic premises for searching a new view of textbook. 1) Textbook should not be considered as the only material but as being at the center of various teaching -learning materials. 2) The importance of textbook should be illustrated Among Curriculum, textbook and related teaching-learning materials, instruction and evaluation. 3. Textbook contents should not be regarded as definitely fixed or absolute ones. 4. Human being can understand environment more fully by commanding his swnsory organ multilaterally. Under these premises we disscussed about curriculum and textbook, textbook, and instruction, akd evaluation method.

  • This study analyzed the problem associated with inquiry centered science education and formulated some improvement Strategies for inquiry learning in the standard Korean high school course. In order to attain the goals of questionaire survey methods were used. To examine the current status of biology education, seperate questionaires were developed through an educational research and development procedure used for tearchers and student. The questionaires were developed to ask about instruction and evaluation methods, the level of inquiry learing and abstacles to it. Here are some of our results: 1) Biology instruction and learning is more knowledge-orinted than inquiry-orinted, 2) Inquiry approach in science teaching is hard to be applied because of crowed classroom conditions. 3) The material is too broad in range and too difficult in content. There is virtually nothing that can be related to everyday life. The material focusing on inquiry activities is unsatisfactorily selected and organized. 4) Effective methods of inquiry-based instruction and evaluation are not available. 5) Biology teachers are burdened with too many class hour a week and too many varieties of additional works. 6) 91.1% of biology teachers and 90.3% of students recognize that lab and field works are needed to enhance inquiry learning. However, in reality, such inquiry activities are lacking. 7) 73.3% of schools have no lab assistants. 8) The university entrance examination is the greatest factor against inquiry learning. 9) There are very few chances of in-service education for biology teachers to learn more about biology curriculum and science education theory.

  • The research reported in this study focused on an analysis of argumentation in the inquiry discourse among pre-service science teachers. For about 3 months, 7 groups of 24 pre-service science teachers participated in an open-ended inquiry and performed 10 inquiry discourses. All discourses were collected by video-recording and transcribed. To analyze features of argumentation discourse, analytic tools derived from Toulmin's argument pattern and cognitive argumentation scheme were applied to discussion transcripts. The results were as follows: First, the order of frequency in the analysis of 'meaning unit' was 'claim-warrant-data-rebuttal-backing.' Second, the order of frequency in the analysis of 'dialogue unit' was 'CW-CD-CDW-CWR-CR'. Third, more rebuttals were found than other discussions. Fourth, the second argumentative discussion showed a higher level than the first.

  • This study investigates the types of teacher feedback in the process-centered assessment for scientific argumentation. The process-centered assessment visualizes the process of developing scientific argumentation at a group level. Four teachers and 353 high school students participated in this study. We analyzed video recordings, the collaborative modeling-argumentation papers, and teachers' interviews. The findings indicate that the teachers provided feedback on scientific concepts and the development of small group argumentation. We presented a representative case for each category in detail. The study suggests that teachers' efficient use of feedback leads to improvement in students' self-regulation. This study contributes to providing specific and useful guidelines on the use of process-centered assessment for enhancing students' scientific argumentation.

  • The aim of this study is to analyze the effect and limitation of teacher librarians' self-reported appraisals and suggest it's activation plans about school library based instruction (SLBI). According to results of analyses, the SLBI begin with subject teachers' demand for learning materials and teacher librarians play their educational role in Information search & access and representation & synthesis of information during the instruction. Compared with previous studies, the limitations of SLBI we can see in this study are restricted role of teacher librarians, exclusive attitude and antipathy to classroom opening of subject teachers under the SLBI. The bars of promoting the SLBI are also the difficulty of collaborative working with several same subject teachers and subject classroom system. The ways of activating the SLBI suggested in their self-reported appraisals are building intimacy with subject teachers and participating actively curriculum council, peer-supervision and demonstration classes.

  • The purpose of this study was to analyze the differences in the understanding level of the Korean traditional seasonal customs during summer (i.e. Buddha's birthday, Dano festival, Yudu festival and Chilseok) before and after the execution of a educational program concerning seasonal customs and determine if elementary school teachers recognize a need for this kind of educational program. The subjects of this study were 168 students in the 4th grade at two elementary schools (84 students each for the experiment group and the control group) and 249 teachers at the elementary schools in Yangju city. The major results of this study are as follows : First, it was shown that there is no significant difference in the understanding level of seasonal customs between the experiment group and the control group in the pre-test, but after carrying out the educational program, it was indicated that there is a statistically significant difference between the experiment group and the control group in the post-test. Second, in addition to strongly pointing out the necessity of seasonal customs education, the teachers recognized that it is desirable to teach seasonal customs to students through the discretionary activity class corresponding to the seasonal divisions in the year and that it is especially important to perform the educational activity through traditional plays and to utilize audio-visual media. Also, teachers hoped that a seasonal customs program suitable for elementary school students would be required, along with the development of instructional materials, and finally that the schools need to further develop teacher training through field inspections and practice.
