  • The dissemination of scientific information in Society involves interactions among a number of publics and many kinds of information channels. There is a need for examining the the entire process of information dissemination for the solving many problems which scientific many problems which scientific communication is now confronted with, This paper is an attempt to identify the functions of a scientific journal as one of major inf. transfer media, to clarify the problems in performing the functions, and to synthesize various on-going efforts toward the improvement and solution of such problems. Some conclusions derived from this study are as follows; (1) a scientific journal was, is and will be the valuable primary source for the recording and controlling scientific in formation which plays a role as a main energy source in the scientific activities. (2) Traditional built-in delays involved in the communication by a scientific journal should be improved by way of some new methods and techniques such as, of establishing a publishing center, controlling vocabularies in the scientific papers, distributing pre-publication materials, etc. (3) There should be a organized special committe for scientific communication for the assuming the responsibilities of educating, planning and carrying out activities relating to scientific information. (4) To improve the function of a scientific journal as information transfer media, other informal primary media such as report, preprint, etc, and secondary media such as abstracts and indexes should be studied which will result in the clarification of unigue functions, and advantages and disadvantages of each media. as an information dissemination media. (5) Each government should pay attention to the national information system as a changing social system and should recognize the gap in speed between technological development and the change of a social system Technological development should be made a contribution to the improvement of social system.

  • The purpose of this study was to develop performance assessment materials of scientific inquiry skills on sixty scientific activities in elementary science textbook for fifth and sixth grades. For this study, a total of 500 elementary teachers were sampled and surveys were carried out to examine the status of performance assessment of scientific inquiry skills in school. The classification system of assessment methods by Hart(1994) was also analyzed to create' assessment strategy of scientific inquiry skills' for elementary school students. Based on the quantitative data analysis and literature study, performance assessment materials were developed and applied to science classes for fifth and sixth grades. Teachers and students were interviewed after the classes for asking about merits and improvements and the performance assessment materials were revised. This study can provide elementary school teachers with reliable sources for performance assessment of scientific inquiry skills utilized in their science classes.

  • Nowadays users spend more time and effort to find what they want because of information overload. To solve the problem, scientific article recommendation system analyse users' needs and recommend them proper articles. However, most of the scientific article recommendation systems neglected the core part, user profile. Therefore, in this paper, instead of mean which applied in user profile in previous studies, New TPIPF (Topic Proportion-Inverse Paper Frequency) was applied to scientific article recommendation system. Moreover, the accuracy of two scientific article recommendation systems with above different methods was compared with experiments of public dataset from online reference manager, CiteULike. As a result, the proposed scientific article recommendation system with TPIPF was proven to be better.

  • 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 research suggests science inquiry play of analogy as a teaming method to help the students in concrete operational stage to develop scientific thinking skills and to understand abstract science conceptions. The research focuses on/considers the characteristics and merits of the science inquiry plays, and the learning method by analogical reasoning. This learning through the science inquiry play of analogy can be considered as a meta-model for scientific thinking skill. The learning has the following processes: 1) Students analogize the abstract science conceptions and facts into play-type activities including the concrete contents such as students themselves, their physical-sensory motions, concrete objects, play methods, and play rules. 2) Students as analogized objects play a role physically and sensuously according to the methods and rules analogized in the play. 3) Students find out the concrete contents included in the science inquiry play of analogy, draw the results, and deduce the new conceptions from the results by reflective thinking and analogical reasoning.

  • In this investigation of the effectiveness of the Project Approach Method the 32 4-to 5-year-old subjects (16 each in the experimental and comparative groups) were pre-tested before the Project Approach Method was applied (23 times over 7 weeks) in the experimental group while the comparative group had science activities using standard unit methods of instruction. Then, all the children had a posr-test. Data were analyzed by t-test and ANCOVA. Results showed differences between the experimental group and the comparative group in their scientific problem solving ability. Specifically, effects were found on 14 sub-factors, but no difference were found on 3 sub-factors.

  • Looking at the understanding of scientific concepts from a linguistic perspective, it is very important for students to develop a deep and sophisticated understanding of words used in scientific concept as well as the ability to use them correctly. This study intends to provide the basis for productive knowledge education of scientific words by noting that the foundation of productive knowledge teaching on scientific words is not well established, and by exploring ways to teach the relationship among words that constitute scientific concept in a productive and effective manner. To this end, we extracted the relationship among the words that make up the scientific concept from the text of science textbook by using quantitative text analysis methods, second, qualitatively examined the meaning of the word relationship extracted as a result of each method, and third, we proposed a writing activity method to help improve the productive knowledge of scientific concept words. We analyzed the text of the "Force and motion" unit on first grade science textbook by using four methods of quantitative linguistic analysis: word cluster, co-occurrence, text network analysis, and word-embedding. As results, this study suggests four writing activities, completing sentence activity by using the result of word cluster analysis, filling the blanks activity by using the result of co-occurrence analysis, material-oriented writing activities by using the result of text network analysis, and finally we made a list of important words by using the result of word embedding.
