  • 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.

  • Creativity is always important in science gifted education. There are many research results about enhancing the creativity. One of the ways of enhancing students scientific' creativity is to let them think and research like scientists so that they can follow how scientists find problems and solve them. So in this study, scientific creative elements were extracted from the Pauling's detailed examples of research process by using many documents. Abductive reasoning, paradox, changing the perspective, modeling, simplifying, converging thinking, diverging thinking, and metaphorical thinking are thinking methods that were extracted from the Pauling's research process. Repeated experiment, co-experiment, using both theories and experiments, and social obligation as a scientist are research methods. Scientific creative elements that were extracted suggest some direction that have more scientific creativity, more ability to find problems, and more ability to form theories in science education or in science gifted education.

  • In this study we have developed programs to enhance the scientific creativity by reviewing literature on the creativity and analyzing the theoretical models related to gifted education. The scientific creativity is regarded as the process of problem solving and problem finding, in particular, solving and finding the ill-defined but significant problems. In general, the important components of the scientific creativity are considered as the scientific knowledge, process skill, divergent/critical thinking, ill-defined problem, and problem finding. The program developed for the purpose of the study is composed of three stages based on Renzulli's model : general exploratory activities, group training activities and individual and small group investigations of real problems. The developed program in this study consists of 4 themes, 15 school hours in the earth science area. The process and products of the program development as well as the background of the present research are described and discussed in detail.

  • 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.

  • In the process of establishing the principle of genetics, Mendel discovered problems based on various observations. Mendel's scientific thinking ability can be effective if this ability is embedded in gifted science education programs. The study aims to develop a science gifted education program utilizing Mendel's scientific thinking ability shown in the principles of genetics and examine students' changes in scientific thinking ability before and after the program implementation. For the program development, first, the characteristics of Mendel's scientific thinking ability in the process of establishing the principle of genetics were investigated and extracted the major elements of inquiry. Second, the science gifted education programs was developed by applying the inquiry elements from the Mendel's Law. The program was implemented with 19 students of $7^{th}$, $8^{th}$ graders who attend the science gifted education center affiliated with university during July 2011. The Mendel's scientific thinking ability was classified into induction, deduction, and integration. The elements of inquiry extracted from the Mendel's scientific thinking include making observation, puzzling observation, proposing causal questions, generating hypothesis, drawing inference, designing experiment, gathering and analyzing data, drawing conclusions, and making generalization. With applying these elements, the program was developed with four phases: $1^{st}$ - problem finding; $2^{nd}$ - hypothesis generating; $3^{rs}$ - hypothesis testing and $4^{th}$ - problem solving. After implementation, students' changes in scientific thinking ability were measured. The findings from the study are as follows: First, students' abilities of problem finding is significantly (p<.05) increased. Second, students' abilities of hypothesis generating is significantly (pp<.05) increased.

  • 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.

  • The purpose of this study was to explore science teacher's epistemological understanding of science and science teaching and learning, from the perspective of inquiry as the process of scientific knowledge building. Three science teachers participated in this study. The data were collected from individual in-depth interviews and classroom videotaping. The results show a case involving coherent and consistent data. It showed that the teacher's epistemological understanding of science and science teaching and learning consisted of five categories: scientists doing science with scientific thinking; scientific thinking as the process of knowing; science learner in the learning process of scientific thinking; science teacher as a man/woman with good understandings of science; and teaching and learning as the process of knowing science. Based on the results, discussions and implications about science education and science teacher education were presented.

  • 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.
