  • The purpose of this study is to quantitatively and qualitatively analyze the science journals written by pre-service elementary school teachers, and to categorize the view on the nature of science and the process of their change. For this purpose, 112 science journals written by 13 pre-service elementary school teachers were analyzed. The frequency of each area was analyzed using the research framework of the four areas of the nature of science, and the pattern of change in perspective on the nature of science was inductively derived and classified using the VNOS-C test analysis framework. As a result, The nature of scientific thinking, nature of scientific knowledge, nature of STS, and nature of scientific inquiry were described in relatively similar proportions, but among them, The nature of scientific thinking appeared in the largest percentage, and the nature of scientific inquiry was described in the smallest percentage. The variability of scientific knowledge, the importance of empirical evidence, and the positive and negative effects of science were especially intensively addressed. In addition, the changing aspects of pre-service elementary school teachers' perspectives on the nature of science could be categorized into 'naive view maintenance type', 'informed view maintenance type', 'regression type', 'development type', and 'mixed type'. The element of 'the empirical nature of scientific knowledge' showed various patterns of change depending on the students, and most of the students maintained a informed view on the tentativeness of scientific knowledge for several sessions.

  • We studied what kind of science-contents problems can also give information on one's creativity for use in the selection of scientifically gifted. 383 7th and 8th graders as subjects, we first analyzed the corelation between the results of creative thinking, scientific attitude, science inquiry, logical thinking and the scientific creativity problem solving skill test. The corelation analysis indicated that science inquiry test could represent other tests except TTCT. We then tested 532 6th graders with TTCT and science inquiry tests concomitantly with the contents- related problems made in such types as naming 20 scientists, writing about a scientist, imagination to overcome a problem, understanding of theory and application and understanding of science laws and application. The results indicated that writing and imagination were most efficient in assessing both the contents and the creativity.

  • The purpose of this study is to analyze the variation in pupil size as shown in the scientific hypothesis generation process of students in Elementary School. The subjects for research consisted of 20 fifth-year students at Seoul B elementary school who agreed to participate in the research. The task consisted of four scientific hypothesis-generating tasks. SMI's Eye Tracker(iView $X^{TM}$ RED) was used to collect eye movement data. Experiment 3.6 and BeGaze 3.6 softwares were used to plan experiment and analyzed the task performance process and eye movement data. The findings of this study are twofold. First, there were four types that generate hypothesis about the tasks. Second, in the moment of generating hypothesis, participants' pupils have grown bigger. And while thinking of generating hypothesis or elaborating hypothesis, there were no big changes. These results show the moment of generating hypothesis is affected by emotional factors besides cognitive factors.

  • This study analyzed the kinds and frequencies of descriptors in 154 articles in ERIC data base on the 4th day of January in 2010. The titles of the articles includes the words, 'scientific literacy'. As each descriptor is constituted of two words and over, in this study the first word in the descriptor was defined as 'restrictive word' and the rest word(s) as 'target word(s)'. The results are as follows. First, the descriptors which show high frequencies of target words are the traditionally important themes of scientific literacy education. Target words which show relatively high frequency are 'education', 'literacy', 'instruction' and 'countries'. Low frequency word is 'curriculum', which has various restrictive words and represents wide differentiation. Second, among the descriptors which show low frequencies of target words, relatively high frequency descriptors are '(and)society', 'change', 'secondary education', 'concepts', and 'biology', which have been given more attention in scientific literacy research than the rest descriptors. Third, the number of the descriptors that shows largely distributed pattern A, which happens over 15 years continuously, is over the half of all analyzed descriptors, which shows that they have been the major objectives in researches about scientific literacy. Most descriptors of pattern A shows normal distribution of frequency or the trends of increasing frequency as the time is nearer. Fourth, The descriptors are divided into four groups according to the time span. Each research trends are as follows. In later 80s, the research which emphasizes the importance of the sociality and technology in all level school science curriculum. In later 90s the research for educational change of inquiry-centered science curriculum which considers technological literacy in social contexts. In earlier 2000s the research that scientists and science teachers develop science curricula mostly related to scientific principles and thinking in chemistry and biology especially. In later 2000s case studies which relates teaching methods and science process activities to students' attitudes, scientific concepts and curricula.

  • This study examines the effects of the introduction of artistic and technological factors on science problems for the activation of creative and integrated thinking. We developed problems consisting of STA(problems that introduced technological and artistic factors on the College Scholastic Ability Test) and TA(problems that introduced artistic factors in a technological context). Subjects of the study included 60 high school senior students in Daegu. Their problem solving processes for STA were examined. Four students were interviewed using the retrospective interview method. Also, after finishing TA, the problem solving processes of four students were examined. The results of the study are as follows. First, students selected scientific context more than artistic and technological contexts. It was found that students preferred short length problem in order to solve problems in a short time. Second, students were more interested in artistic and technological contexts of STA than scientific context, but felt that they were more difficult. Moreover, students were more interested about the context of TA than scientific context. Third, irrespective of the given contexts in STA, students have a tendency to solve problems through relatively brief ways by using core scientific knowledge. This can seem to mean that there is a possibility to stereotype the problem solving process through repeated learning. Logical thinking and elaboration were observed, but creativity was not conspicuous. In addition, integrated thinking was not observed in all contexts of STA. Fourth, science related problems of TA showed similar results. However, in problems related to everyday life, students made original descriptions that they based on their daily lives. Particularly, in creative design, original ideas and integrated thinking were observed.

  • The purpose of this study was to find the effect of intuitive free association and systematic free association on the creativity of high school students group in the conceptual design process. Based on this study result, the conclusion can be summarized as follows. 1. There was meaningful relation between intuitive free association and creativity factor of high school students. Mean value of experimental group A 's creativity and it's factor originality, practicality, elaboration, and fluency which treated intuitive free association was increased. 2. There was meaningful relation between systematic free association and creativity factor of high school students. Mean value of experimental group B 's creativity and it's sub factors: originality, problem solving, elaboration, and fluency which was treated systematic free association was increased. 3. It was found that two different divergent thinking does not show any meaningful difference in creativities of two groups. However, the meaningful difference was found in post creativity test in each groups sub-factors. There was meaningful difference in practicality factor, though there was no meaningful difference in originality, elaboration, fluency factors. Using the obtained results, it was concluded that intuitive thinking and systematic thinking play different roles in practicality which is one of sub-factors of the creativity of high school students. Consequently, it can be concluded that systematic thinking which leads students to take a step to solve a given problem can elicit more scientific thinking, and helps students create more practical solution in problem solving than intuitive thinking that emphasize the quantitative aspect of ideas.

  • An inquiry approach in teaching science has been advocated by many science educators for the past few decades, and most elementary and secondary science curricula have incorporated it in varying degrees. It has been proven in recent studies, however, that there exists considerable discrepancy between the expectation of outcomes of the inquiry approach and the actuality. This in part implies that there is a somewhat urgent need for the systematic evaluation of the approach in teaching science. The purpose of this study is to develop a comprehensive instrument for evaluating inquiry teaching approaches embedded in science curricular materials. To develop a more valid and reliable instrument a set of empirical data was used in the developmental procedure, and most of the previous studies regarding inquiry teaching method and inquiry evaluation were consulted. The inquiry evaluation method developed in this study, called the Scientific Inquiry Evaluation Inventory (SIEI), is composed of three parts: (1) analyzing and coding each science process task of inquiry activity; (2) evaluating each inquiry activity as a whole; and (3) evaluating each science laboratory curriculum as a whole. The first part of the instrument consists of twenty science process categories and thirty subcategories grouped into four sections: (1) gathering and organizing data; (2) interpreting and analyzing data; (3) synthesizing results and evaluation; and (4) hypothesizing and designing an experiment. The science process categories are arranged according to the level of difficulty, psychological level of thinking, degree of creativity demand, and the model of the process of scientific inquiry, which is also developed in the study. The second part of the instrument contains four evaluation scales of inquiry activity: (1) competition/cooperation scale; (2) discussion scale; (3) openness scale; and (4) inquiry scope scale. And the last part consists of three methods for evaluating a science laboratory curriculum as a whole: (1) inquiry pyramid; (2) inquiry index; and (3) difficulty index. The instrument is designed to be used by teachers, science curriculum developers and science education evaluators for the purpose of diagnosing the nature and appropriateness of scientific inquiry introduced in secondary science curricular materials, especailly in laboratory work and field work.

  • The purpose of this study was to develop forensic science program for the improvement of scientific creative problem-solving abilities in gifted elementary-school students. A program that consists of six sessions (18 hours) is developed in accordance with the CPS model, which has been already proven effective for the improvement of creative problem-solving abilities. This program was applied to sixth-grade 18 gifted students in an elementary school in Gyeonggi province. Examinations of scientific creative problem-solving abilities were performed before and after applying the program in order to determine its effect on gifted elementary students. A qualitative analysis of students' activity sheets, peer assessment and teacher's class journal was made in order to examine the process of improvement of students' scientific creative problem-solving abilities. The results of this study are as follows: First, forensic science program to enhance the scientific creative problem-solving abilities of gifted students was developed. Second, forensic science program is significantly effective in the improvement of scientific creative problem-solving abilities of gifted children of elementary school (p<.05). Third, in early stage of the class, a student, who showed the highest range of change in pre and post tests, revealed the trend of responding in a short answer type. In the late stage of the class, he revealed the capability of producing various creative ideas promptly. On the other hand, students belonging to the upper group of both pre and post test revealed the improvement of divergent thinking skills such as fluency, flexibility, and originality. Fourth, after class, the students responded that the forensic science program developed in this study intrigued the interests and curiosities, and helped them break away from fixed ideas.

  • This study was to examine the differences of behavioral characteristics between scientifically gifted students and ordinary students. The subjects were 40 scientifically gifted students (27 males and 13 females) and 38 ordinary students (21 males and 17 females). The study specifically analyzed the several characteristics including logical thinking, science process skills, creativity, earth science creativity, self-directed learning, and cognitive style. The results were as follows; First, while 94.74% of scientifically gifted students reached the formal stage, only 36.36% of ordinary students reached it in logical thinking. Second, scientifically gifted students gained higher scores than ordinary students did in science process skills (average 8.11), creativity (average 8.27), earth science creativity (average 6.73), scientific attitude (average 10.79), self-directed learning (average 21.60). Third, 70% of scientifically gifted students and 60.53% of ordinary students showed to have the characteristics of field independent thinking. These results implied that the behavioral characteristics of scientifically gifted students should be included in science gifted education for the pursuit of the essential gifted education and maximization of its efficiency.

  • The purpose of this study was to develop instructional strategy for newspaper-based science writing and to examine the effect of its application. The target unit was 'change of weather' and 'a variety of gas' in the sixth grade of elementary school, and the teaching strategy was composed of 3 stages-writing including realistic, interpretative and comprehensive writing. The result of applying this strategy into actual classrooms was as follows. First, it was proven that the science writing strategy using newspaper articles actually helped improving science process skills of learners, in particular, integrated process skills. Second, this strategy for science writing changed the scientific attitude of learners positively. While they read the newspaper articles, their thinking became more elaborate and systemized, which seemed to serve to foster their openness, criticism, and perseverance. Third, the science writing strategy did not contribute to the improvement of learners' science study achievement. To improve the understanding of scientific concepts and principles of learners, it is needed that teaching program combines with argument-based activity organically. The above-mentioned findings show that this instructional strategy using newspaper articles can be applicable as one of effective methods in science writing.
