Although the development of scientific thinking is one of the significant goals in science education in schools, there is a lack of empirical research on how science teachers conceptualize scientific thinking. This study explored how four pre-service secondary-level science teachers conceptualized scientific thinking and elaborated their conceptions through peer discussions. Results involved each pre-service teacher's conceptual spectrum of scientific thinking and showed the process of elaboration in their conceptions about three crucial issues in small-group or larger discussions. Three issues related to scientific thinking included everyday vs. scientific thinking, the relationship between science knowledge and scientific thinking, and the relationship between logical systems and evidence. Implications for pre-service science teacher education were discussed, and further research was suggested based on the results of this study.

In this study, 46 teaching materials for understanding the nature of science (NOS) were developed based on the 42 statements describing the NOS. Each teaching material involves scientific knowledge and scientific inquiry skills as well as NOS statements. Teaching materials consist of students' learning worksheets and teachers' guides. Among the materials, 11 materials for understanding the nature of scientific thinking (NOST) were applied to 3 scientifically gifted students. As results, the degree of difficulty was appropriate and students showed interests in scientific thinking rather than new concepts or inquiry activities involved in the materials. It was expected that understating the NOST would be helpful for conducting scientific inquiry in more authentic way. And similarly to the Park's (2007) theoretical discussions about the relationship between the NOS and scientific creativity, students actually responded that undertrading the NOST could help their creativity. Therefore, it was expected that teaching the NOST would be plausible elements for teaching scientific creativity.

This study explored the effect of using the inquiry-based science writing heuristic approach in class on metacognition and scientific creativity to enhance the ability of solving problems in science classrooms of elementary students. The results of this study were as follows. First, the science writing heuristic had a positive influence on the usage of metacognition necessary for learners to solve the problem with science. Second, the science writing heuristic contributed to the improvement of scientific creativity. In the process of inquiry-based approach, learners used scientific knowledge to come up with ideas and produce outcomes, therefore they could seek sanswers to scientific problems for themselves. Third, the science writing heuristic produced a positive awareness of science process skill because learners had more opportunities to think on their own than an existing passive class. In conclusion, this study found that the inquiry-based science writing heuristic approach encouraged learners to do inquiring activities in school classrooms, therefore contributing to the application of metacognition and the improvement of scientific creativity.

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.

Language skills in science education seem to have a great impact on student achievement. Most of the language skills affecting students' science learning can be accounted for an understanding of scientific terms. The ultimate goal of this study is selecting and grading the scientific terms for science education. As a basic research, we investigated scientific terms contained in science textbooks, because they are the most basic and selected terminologies. As a result of investigation of scientific terms in physics units of middle school science textbooks, we made a list of 556 scientific terms by grade level. This includes 249 words for grade 7, 170 words for grade 8, and 137 words for grade 9.

The purposes of this study were to investigate the creative science problem solving (CSPS) process amongst scientifically-gifted students and average students through the qualitative think-aloud research method, and to compare the differences in their CSP, scientific knowledge, scientific process skills, creative thinking, and finally, the affective domain used in their CSPS. For the purposes of this study, two scientifically-gifted 6th grade students and one average student were selected. The results show that one gifted student with good creative thinking skills exhibited better performance in CSPS than the other gifted student, who had the highest level of scientific knowledge. In the case of the average student, in spite of her high level of factual knowledge, she had difficulty in proceeding in CSPS due to her shallow scientific knowledge along with her low level of understanding of the given problem. This study highlights the importance of considering the factors which influence successful CSPS and which can play an important role in the education of scientifically-gifted children. These factors were identified as scientific knowledge, understanding of the scientific process, creative thinking, the affective domain, and science problem solving skills.

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.
