This study aimed to investigate the characteristics of pre-service elementary teachers' understanding about scientific inquiry in terms of designing exploration and reasoning that is used to formulate explanations based on evidence. The research context was an open inquiry with using the Science Writing Heuristic (SWH) template in which participant students were not provided with inquiry questions. As data, lab. 39 pre-service elementary teachers participated in this study while taking their science methods course. Analyses of the reports were framed by the cognitive processes of inquiry (Chinn and Malhotra, 2002) and each report was coded and analyzed by the framework of inquiry (Tytler and Peterson, 2004). Results showed that groups' works that utilized the SWH template encouraged the participants to interact each other about scientific inquiry. They came up with more relevant and testable questions for their scientific inquiry. It implicates that children will be able to have chances of testing their own questions more properly by using the SWH template in science classes just as the participants did in this study. The use of the SWH template would help pre-service teachers to teach appropriately how to test inquiry questions to their students in the future. Discussion was made to figure out the characteristics or Korean pre-service elementary teachers' understanding about scientific inquiry.
This study examined the effect on the education of scientific attitude in the process of primary school education by application of STS teaching-learning method with an unit of 6th grade in primary school "environmental pollution and nature conservation". The attitude relating science education, on the other side, is classified into 4 parts; attitude for science, social meaning of science, attitude for science subject and scientific attitude. The study of sexual difference on the above points was examined too. The results was taken as follows. 1. STS Teaching-learning method gives positive effect on the education of scientific attitude more than traditional teaching method, especially on the point of the attitude of science lesson and scientific attitude. 2. STS education has an great influence on the social meaning of the scientific attitude relating science education , investment in science, relation with society, solving social problem, contribution to development of society and technology 3. STS teaching-teaming is thought to be the learning that is more effective for boy than girl. In conclusion The STS Teaching-loaming method is preferable in order to increase the scientific attitude of the Elementary school students. students.

The high school students' problem solving patterns and their features in scientific inquiry, especially on controlling variables and stating hypothesis have been investigated. The 8 problems on controlling variables and stating hypothesis were selected out of the scientific inquiry area in the experimental tryout of Aptitude Assessment for College Education, and had been used to find the patterns and their features. The results of findings are as follows: There were seven patterns in the process of solving problems. Five of seven patterns were found in right answers and four patterns in wrong answers. Two patterns were found in both right and wrong answers. Some students could solve the problems even though they did not understand the elements of the scientific inquiry, controlling variables and stating hypothesis. The false application of physics concepts, misunderstanding about the elements of the scientific inquiry and using unrelated experience and conjectures were the features of students' wrong answers. On the other hand, the right application of physics concepts, understanding and applying the elements right, infering answers from the tables and figures on statements of suggested problems were the features of right answers. The further studies on this kind may helpful to find the higher mental abilities related to scientific inquiry and to develop tools for testing students' scientific inquiry thinking skills.

Scientific communication is an information exchange activity between scientists. Scientific communication is carried out in a variety of informal and formal ways. Basically, informal communication takes place by word of mouth, whereas formal communication occurs via the written word. Science is a highly interdependent activity in which each scientist builds upon the work of colleagues past and present. Consequently, science depends heavily on scientific communication. In this study, three mathematical models, namly Brillouin measure, logistic equation, and Markov chain are examined. These models provide one with a means of describing and predicting the behavior of scientific communication process. These mathematical models can be applied to construct quality filtering algorithms for subject literature which identify synthesized elements (authors, papers, and journals). Each suggests a different type of application. Quality filtering for authors can be useful to funding agencies in terms of identifying individuals doing the best work in a given area or subarea. Quality filtering with respect to papers can be useful in constructing information retrieval and dissemination systems for the community of scientists interested m the field. The quality filtering of journals can be a basis for the establishment of small quality libraries based on local interests in a variety of situations, ranging from the collection of an individual scientist or physician to research centers to developing countries. The objective of this study is to establish the theoretical framework for informetrics which is defined as the quantitative analysis of scientific communication, by investigating mathematical models of scientific communication.
This study explores how elementary school students construct food pyramid prediction models using scientific reasoning. Thirty small groups of sixth-grade students in the Kyoungki province (n=138) participated in this study; each small group constructed a food pyramid prediction model based on scientific reasoning, utilizing prior knowledge on topics such as biotic and abiotic factors, food chains, food webs, and food pyramid concepts. To understand the scientific reasoning applied by the students during the modeling process, three forms of qualitative data were collected and analyzed: each small group's discourse, their representation, and the researcher's field notes. Based on this data, the researcher categorized the students' model patterns into three categories and identified how the students used scientific reasoning in their model patterns. The study found that the model patterns consisted of the population number variation model, the biological and abiotic factors change model, and the equilibrium model. In the population number variation model, students used phenomenon-based reasoning and relation-based reasoning to predict variations in the number of producers and consumers. In the biotic and abiotic factors change model, students used relation-based reasoning to predict the effects on producers and consumers as well as on decomposers and abiotic factors. In the equilibrium model, students predicted that "the food pyramid would reach equilibrium," using relation-based reasoning and model-based reasoning. This study demonstrates that elementary school students can systematically elaborate on complicated ecology concepts using scientific reasoning and modeling processes.
The purpose of this study is to develop a student-led instructional strategy that is central to the teaching-learning process and to investigate its effects. For this study, we analyzed the learner-centered learning types (discovery learning, problem-based learning, inquiry learning) and extracted elements applicable to newly developed teaching-learning. Based on this, a student-led class strategy was established using pre-learning, teacher collaboration, small group composition, and limited open data and product presentation, and then science classes were conducted. As a result of the post-tests of the five science core competencies of the experimental group using the student-led instructional strategy and the comparative group conducting lecture-based classes, the experimental group showed higher scores than the comparative group in the scientific thinking, scientific communication, and scientific attitudes (p<.05). Based on these results, it was confirmed that the student-led class, in which the student self-adjusts the entire process of designing, exploring, and presenting learning, can help the student's scientific ability. In addition, I would like to discuss the implications of teachers' teaching-learning composition.

This study is intended to investigate the frequency of scientific writing tasks in Korean and American science textbooks, to compare the differences in types of posing the writing tasks according to the level of the children's scientific cognition, and to analyze the differences in the organization and development of writing ones of each chapter and thus to propose an effective way of presenting scientific writing in science textbooks. Korean 'Science' and 'Experiment Observation Workbook'and Macmillan Mcgraw-Hill(MMH) Science for fourth graders were analyzed for the purpose. The results are as follows: First, Korean textbooks contain more science writing tasks per pages, and less per chapters than MMH one. Both text books provide balanced amount of science writing tasks, yet MMH especially does systematic exercises for each chapter. Second, the qualitative analysis of the textbooks' scientific writing shows that both textbooks contain a significant amount of "understanding" and "explanatory" writing, which reflects that the purpose of writing in science textbooks is leaning towards acquiring and verifying scientific concepts. In American textbooks, however, writings utilizing extensive cognition process and materials are also present. It is necessary for textbooks to present diverse and expressive writing assignments including personal opinions. Third, there are differences in organization and development of science writing tasks. Science writing tasks in Korean textbooks are present independently with lesson objectives of the chapters and practices, while those in MMH are systematically developed. Based on these results, it is necessary to systemize the textbooks' way of presenting writing tasks for effective teaching and learning. By organizing the writing materials and thus developing diverse materials, and by implementing extensive cognitive process in the writing activities, textbooks will be able to contribute in attracting the students' interests and in improving their scientific knowledge.
