  • This study has been performed in order to achieve three objectives. They are as follows: To analyze, based on the research literatures, the nature of scientific inquiry ability and the characteristics of its constitutive elements. To identify inquiry skills and techniques essential to such areas as physics, chemistry, biology. and earth science. To develop instructional models and materials for enhancing inquiry ability on the part of high school students. It was found in the study that the scientific inquiry was interpreted in terms of different meanings according to the viewpoint of the person who are interested in the nature of science. The scientific inquiry has been viewed as the process of knowledge formation, scientific method, inquiry process or process skills depending on the epistemological, methodological, educational perspectives, respectively. It was also identified that certain kind of skills or techniques would be used for inquiry in only one specific area of the science. This study drew a conclusion based on the findings that the skills and techniques will effectively be learned when those are taught with specific knowledge in each area of the science. Reported in this paper are the materials developed, for fostering scienctific inquiry skills on the part of the high school students. The materials were developed, using two themes of a theoretical-abstract chemistry topic and a conceptual-concrete biology topic. Those materals were designed for an experiment and an observation, respectively.

  • Indexing allows converting raw document collection into easily searchable representation. Web searching by Google or Yahoo provides subsecond response time which is made possible by efficient indexing of web-pages over the entire Web. Indexing process gets challenging when the scale gets bigger. Parallel techniques, such as MapReduce framework can assist in efficient large-scale indexing process. In this paper we propose PDFindexer, system for indexing scientific papers in PDF using MapReduce programming model. Unlike Web search engines, our target domain is scientific papers, which has pre-defined structure, such as title, abstract, sections, references. Our proposed system enables parsing scientific papers in PDF recreating their structure and performing efficient distributed indexing with MapReduce framework in a cluster of nodes. We provide the overview of the system, their components and interactions among them. We discuss some issues related with the design of the system and usage of MapReduce in parsing and indexing of large document collection.

  • A study was performed for combination active process between the academical theory and practical design process based on creative thinking process in interior desigv. At first, it was investigated the concepts and characteristics of creativity combined with creativite process of thinking, and also scientific and art characteristics on interior design to be educated together with logical and esthetical concepts required for creative thinking process. In reference with above process, it was systematically established stepwise process of interior design with creative thinking system. As a resualt, creativity in interior design could develop a unique design process combined informations about knowledge and experiences with actual acquirements by individual's experiences. So interior design could be approachable and developed with open-mind and consistently scientific methodology. Also creativity power of interior design could be solved by strategic knowledge acquired by practical experiences and problem solving capability in special branches. Like this, all design activities, including interior design, would be accomplished theoretical background and actual design process under the concepts of practical intension and use. So it would be made creative products by means of detail adapation process based on the theoretical atmosphere, therefore it'll be strongly based on the hardnessing of theoretical value and power. Theory for design process referred to environmental concepts, so including interior design, would not be terminated as for theoretical concepts but be responsible for future of well-developed design by accomplishment of various design adaption method for practical purpose and objectives.

  • In this paper, an Online Scientific Inquiry Learning System was developed with the aim of improving student's scientific literacy and scientific inquiry ability. It was determined that there should be 4 distinct principles applicable to the design of the Learning system. First, it should enrich learner's motivation. Second, it should provide students with the chance for reflecting on the inquiry process. Third, it should emphasize multi-dimensional forms of interaction. Fourth, students should be able to create new information through it. The server system including the database, equation editor, reporting tool, search engine were all utilized for developing the learning system. In addition, the authors produced 24 web-based projects which were guided inquiry activities in which various inquiry abilities (reasoning, prediction, experiment design) could be developed. An Online Scientific Inquiry Learning System is not the only program which could be utilized in improving scientific inquiry abilities, but at the very least, such a system can serve as the prototype for developing an online learning system.
