The purpose of this study was to compare the science philosophical views and instruction strategies for open-inquiry between teachers of science-gifted and teachers of general students. The subjects were 45 teachers of science-gifted and 45 teachers of general students. The major results of this study were as follows: First, there was no differences on the science philosophical views between teachers of science-gifted and teachers of general students by chi-square tests (p<.05). Second, there were no differences on how task assignments, how to guide exploration data, and how to write reports between teachers of science-gifted and teachers of general students (p<.05). But there was meaningful differences on how to proceed with exploration activities between teachers of science-gifted and teachers of general students (p<.05). It is implied that this the results of this investigation will help the focus of future efforts to promote more adequate the science philosophical views and instruction strategies for open-inquiry in teachers of science-gifted.

The purpose of this study was to investigate elementary school students' views on the nature of science and to compare their views by gender. Participants were 159 sixth graders in Seoul. An instrument consisting of five multiple-choice items were developed on the bases of previous studies. At the end of each item, students were also asked to write their reason in details for selecting a specific option. The results indicated that the students' views on the nature of science, on the whole, were neither accurate nor adequate from the viewpoints of modern epistemology. On comparing their views by gender, however, no significant differences were found except the item concerning the 'nature of model'.

The purpose of this study was to examine philosophical views on science of two influential curriculum documents, AAAS' s Benchmarks for Scientific Literacy (Benchmark) and NRC's National Science Education Standards (Standard), and to get educational implications about a desired philosophical view on science at a school science level. In order to determine the philosophical views on science explicitly suggested in the documents, Soh's Philosophical Perspectives Probe (PPP) was used as a framework for analysis. Forty preservice teachers reviewed the documents, extracting paragraphs with which statements of the PPP' s questions would agree. The results of the study were as follows: First, the Benchmark's philosophical view on science corresponds to the borderline between inductivism and eclecticism, or eclecticism close to falsificationism. The philosophical positions by the PPP' s themes are very different. Second, the Standard's philosophical position on science corresponds to inductivism close to eclecticism. Its philosophical position by the themes of the PPP is very different like the Benchmark. These results indicate that philosophical positions of the documents are more complex than popular conceptions would have it. That is to say, the results suggest that the science curriculum documents hold not only a contemporary philosophical view on science but also a traditional view on science, and that the philosophical positions on science are different from each other by documents and even by the PPP's themes in the same document. The results suggest that the philosophical views on science in school science contexts need to be adjusted and presented to K-12 students according to topics related to philosophy of science.

This study aims to find out science talented students' percentage of cognition about the views of nature of science and science inquiry which are essential for having a good understanding with science concepts. Each group of 40 science gifted students and 35 ordinary students was tested with a test of views of nature of science and science inquiry which consisted of 19 items with index of content validity 97% and reliability index 0.86, then its results being compared and analyzed. A group of science gifted students' percentage of cognition about the views of nature of science ranges from 20% to 97.5% -although it differs according to detailed views-showing its mean of 67% (50% in a group of ordinary students). Especially, the percentage of cognition about the sub view that there can be different opinions among scientists was high among woman science gifted students. A group of science gifted students' percentage of cognition about the views of science inquiry ranges from 27.5% to 77.5% -although it differs according to detailed views- showing 53% in their mean (41.8% in a group of ordinary students). Especially, the percentage of cognition about the sub view that scientists can have different research methods was high among woman science gifted students. The percentage of mistaken cognition by science gifted students about views of nature of science and about views of science inquiry was 33%, 47% respectively.

The purpose of this study is to investigate the elementary pre-service teachers' views about "the purpose of science experiments". For the study, the views about the purposes of scientists' experiments and school science experiments were surveyed from 227 pre-service teachers. And the responses were analyzed based on their gender, intensive majors and school science test scores. The main results of the study are as follows. First, in relation to the purpose of scientists' experiments, the pre-service teachers considered internal values of doing experiments were more worthy than the external values of it. In particular, the pre-service teachers responded that the most important purpose of the science experiments is 'to get the evidences for the theories and arguments'. On the other hand, the views from the women and social studies major pre-service teachers were more diverse than those of the man and science major pre-service teachers. Second, in relation to the purpose of school science experiments, the pre-service teachers excessively considered that the internal values of school science experiments were more worthy than the external values. In particular, only few pre-service teachers were aware of social and personal aspects of the experiments, though they considered well that the experiments are useful tools for the school science study. Third, there were quite different aspects of pre-service teachers' views between the purposes of scientists' experiments and school science experiments. For example, the views about the scientist's experiments were relatively broad concerning the nature of scientific experiments, but the school science experiments were just regarded as an educational tool for the science study. Based on the results from the study, some science educational implication were discussed.

In this study, we investigated the influences of Integrated Science and Science Inquiry Experiment developed under 2015 Revised National Science Curriculum on students' interest in science, scientific attitude, views on STS, and the nature of science (NOS). 223 tenth graders in Seoul metropolitan area participated in this study. We conducted the survey prior to and after the Integrated Science and Science Inquiry Experiment course using same instruments and compared the results of the pre-test and post-test. The analyses of the results reveal that there were significant improvements in the scores of the pre- and post-test on the interest in science and scientific attitude. In the case of views on STS, there were significant improvements in items related to science research ethics, however there were no significant differences in the remaining items. Also, there were no significant differences in the scores of the pre- and post-test on views on NOS. On the bases of the results, we discuss educational implications and suggest further studies.

This study was conducted to assess any change in students' views on the nature of science (NOS) after lessons through the activities of model construction and pattern identification. The instrument used to examine NOS views was the Views of Nature of Science questionnaire (VNOS). Four students' responses on VNOS before and after instruction were analyzed. The two levels of their views, novice and expert, were judged by the authors based on criteria set by several science educators. The instruction consisted of six hours of the so-called black box and cube activities developed for model construction and pattern identification, respectively. Students' views were at the novice level in definition of scientific theory, tentativeness of scientific knowledge, difference of hypotheses, theories and laws, model construction, and creativity and imagination in experiments and investigations. Students' views on NOS knowledge such as model and theory have improved for two students after instruction. The improvement seemed to be due to an explicit approach using the activities of model construction and pattern identification. The factors of changes and no-changes of views on NOS were identified and discussed in terms of improvement of the views.

Secondary school students' conceptions about the phenomena of evaporating, condensing, boiling and melting of ice using a modified questionare-about-events method. The specific views at each grade level were also studied. The results of investigation were as following. 1) Students' understanding on the sciencific concepts and terms is superficial and nonscientific. 2) Even though upper grade students have exposed to a considerable science teaching, their views are similar to lower grade students. 3) Certain views on the change of state of water can change with the advanced science teaching. However, some nonscientific views are more popular with the older students than with the younger students.

In order to acquire a precise and quick response to an analytical query, proper selection of the views to materialize in the data warehouse is crucial. In traditional view selection algorithms, all relations are considered for selection as materialized views. However, materializing all relations rather than a part results in much worse performance in terms of time and space costs. Therefore, we present an improved algorithm for selection of views to materialize using the clustering method to overcome the problem resulting from conventional view selection algorithms. In the presented algorithm, ASVMRT (Algorithm for Selection of Views to Materialize using Reduced Table), we first generate reduced tables in the data warehouse using clustering based on attribute-values density, and then we consider the combination of reduced tables as materialized views instead of a combination of the original base relations. For the justification of the proposed algorithm, we reveal the experimental results in which both time and space costs are approximately 1.8 times better than conventional algorithms.

The purpose of this study is to identify how primary students make decision in an anomalous situation of discrepancy between the observation result and their prior knowledge and what is the relationship between their decision and views on science. In this study, the researchers have observed a science class of fifth graders for two months and collected qualitative data such as field note, audio transcript, video-recording, photo and interviews. It is shown that participants experienced three types of subjective observation as listed: expectation-related, theory-dependent and dilemmatic observation. The questionnaire of the students to the views on science reveals that most of them thought highly of empiricism and utility of science. With this result, it is found that they took into account the limitation and provision of experiments while making judgment in an anomalous situation. That is to say, their assessment of experiments and observation is crucial in judgment in the situation that their observation is incompatible with their prior knowledge. The researchers conclude that their views on science may influence their observation and suggest the ways to promote students' ability linked to observation.
