The purpose of this study was to explore the characteristics of elementary science gifted students' modification of scientific explanations based on evidences. For this study, sixteen $6^{th}$ elementary students were participated. The subjects of this study were enrolled in the program for the science gifted. Students were asked to generate initial hypotheses before experiment, and to modify and revise their scientific explanations based on the experiments about water rising in burning candle(s). All the processes of small group discussion during the inquiry were audio-recorded. Students' modification of their scientific explanations were appeared in three types: 1) appropriate connections among evidences, reasoning, and claims, 2) disconnections among evidences, reasoning, and claims and/or use of inappropriate reasoning, 3) scientific explanations without their own understanding. Other problems that students encountered in the processes of modification of their explanations were also discussed.

In this study, we investigated preservice elementary school teachers' awareness of students' misconceptions about several science topics, and the variables influencing their awareness. Seniors (N=106) from an university of education were asked to predict elementary school students' misconceptions on science topics such as phase changes and dissolution. Their conceptions about teaching and learning were also measured. The results indicated that the preservice teachers' predictions about the kinds and/or the ratios of students' misconceptions were different from those reported in previous studies. The low level preservice teachers in terms of the degrees of possessing traditional conception about teaching and learning predicted more students' common misconceptions. The degrees of preservice teachers' constructivist conception about teaching and learning and their major, however, did not significantly influence the numbers of common misconceptions predicted.

For assessing classroom environment, numerous instruments were developed and reported the survey results for science students in science education. In this study I translated Constructivist Learning Environment Scales (CLES) were into Korean versions for elementary school teachers, and measured the reliability. The subjects were randomly selected from three departments of an University of Education in a metropolitan city. All of them were 110 students, who would be elementary school teachers. According to the survey results, pre-service teachers for elementary school have recognized constructivistly for learning environments in an actual forms. In a scale of student negotiation they have most constructivistly recognized learning environment, and moderately in scales of relevance, uncertainty and critical view while they have seldom constructivistly recognized in a scale of shared control. Also Korean version CLES would be an reliable instruments for constructivist assessing learning environments.

The purpose of this study was to investigate the effect of scientific argumentation on argument tasks with incorrect alternative ideas in elementary science classes. The subjects were 41 fourth graders of 2 classes in an elementary school. In the experimental group, argument tasks with pictures including incorrect alternative ideas were suggested in order to facilitate argumentation. Students were asked to perform argumentation with the component of claim, evidence, and reasoning. In the control group, textbook-based traditional instruction was used. The results showed that scientific argumentation activities on argument tasks with incorrect alternative ideas had positive effects on students' science achievement and science-related affective domains. The analyses of students' argumentation revealed that argument tasks with incorrect alternative ideas could facilitate students' participation and exposure of their preconceptions. It also led students to find and connect evidence to support their claims. In some cases, students had difficulty in making appropriate argumentation because of unclear experimental data and/or invalid reasoning. Educational implications were discussed.

In this study, we aimed to look at what dilemmas of science teaching elementary school teachers experience and how they cope with their dilemmas in everyday science classes. Three elementary school teachers participated and qualitative data such as class log, class video, and interview materials were analyzed in inductive ways. The main findings are as follows. First, the dilemmas were classified based on the four factors that make up the science class; teacher, student, learning content, environment. However the dilemmas appeared to be not only one factor involved, but the rest of the factors intertwined. Thus, it was interpreted how the main factors causing the dilemmas conflicted with other factors. Second, the types of teachers' coping strategies to the dilemmas could be largely divided into 'give-up', 'stick to' and 'modified'. In some cases, teachers gave up on what they valued and did not take active action ('give-up'), teachers chose what they valued and made decisions to actively realize it ('stick to'), and in others, conflicts were adjusted by introducing new methods or elements to their classes ('modified'). Based on these results, we discussed that the teacher's dilemmas could facilitate the teacher's learning or professional development.

The purpose of this study was to examine the questioning styles of $3rd{\sim}6th$ elementary science textbooks in terms of frequency, type, and placement of questions. This paper also sought to analyse and compare the kinds of scientific inquiry processes elicited by the questions in the content domains of textbooks. The instrument used was the Textbook Questioning Strategies Assessment Instrument (TQSAI). The average number of questions per book was 129 and the ratio of questions to sentences was 31.9%. The results were summarized as followings. First, many science textbook questions were used for the purposes of explanation or identifying levels of teaming. Second, process skills were located in each content domain, although it was not affected meaningfully. Third, the number of text question was below 3 in each elementary science class. Therefore, an effective questioning development framework is clearly needed for elementary science instruction.

In this study, the analogies on saturated solution generated by elementary school teachers were analyzed in their numbers, materials, and types aspects. The results were also compared with those of general and science-gifted elementary students. A test on the self-generating analogies on the target concept was administered to 111 elementary school teachers, 60 fifth graders at four science-gifted education institutes and 91 fifth graders at three elementary schools. The results revealed that the teachers made more analogies than the general and science-gifted students. In general, both the teachers and the students tended to make the analogies using the materials in family, riding, digestive, and school situations. However, there were a little difference between the teachers and the students in the cases of the analogies using other situations including body/physical activity. Similarly to the cases of the students, the teachers made more functional analogies than structural or structural/functional ones and did more concrete ones than abstract ones. However, they made more verbal, artificial, and enriched analogies than the students. They also made more highly systematic analogies than the general students, and did less ones than the science-gifted students. Educational implications of these findings are discussed.

This research examined the elementary students' level of motivation to learn science and analyzed correlation between scientific experiences and the motivations to learn science. 216 of elementary students in the 5th grade and 207 of elementary students in the 6th grade were surveyed with questionnaire composed of Likert criteria and scientific motivation questionnaire(SMQ), and the results were analyzed by SPSS 18.0 statistics program. The results of this research are as following : First, elementary school students' level of scientific experiences appeared quite low, and boys appeared to have more scientific experiences than girls. For more specific areas, the experiences were more from outside of school rather than inside, and experiences from science class. Second, elementary students' level of motivation to learn science stood relatively high, and boys showed higher level of motivation to learn science than girls. For more specific areas, the level of motivation from internal motivation area was the highest and the lowest was that from the area of anxiety about exams. Third, the scientific experiences and motivation to learn science showed highly static correlation. Experiences both from inside and outside of the school were significantly correlated to the motivation to learn science, and those from outside of the school had higher correlation with the motivation to learn science. Therefore, the scientific experiences should be recognized to play an important role for improvement of the level of motivation to learn science, and the efforts should be made to provide the elementary students with high-quality scientific experiences to develop their level of motivation to learn science.

The purpose of this study was to examine the status and science teachers' perceptions of classes for those gifted in science in elementary school. For this purpose, a number of questions were posed to teachers : 27-item-questionnaires were given to 38 teachers of students gifted in science in elementary schools located in Incheon province. The results of this study were as follows : 1. most elementary teachers were in charge of classes containing students gifted in science, but this was the case with only a few secondary teachers. Therefore, it appears to be more necessary to educate elementary teachers who majored in science content and gifted education. 2. In addition, most teachers had positive perceptions of the needs, attitudes and environments needed for gifted education. Most of them attended 60-hour training programs on gifted education. They thought that it was helpful in understanding the characteristics of gifted students, but they wanted to learn more about actual pedagogical methods through such programs. 3. The teaching methods used in classes for those gifted in science were mainly experimental activities, but there were few opportunities for creative problem solving and project learning. This may be due to limited class time of about one hour every two weeks in this class. 4. When the materials used in class were first developed, they mainly used materials made by the city board of education and selected the theme of interest by themselves. Therefore, there may be problems of duplication of materials or systems regarding the science contents for one year. 5. Furthermore, the themes of the materials used were mostly related in terms of the contents of textbooks than more generally. When planning and managing the classes for those gifted in science, the above points should be considered in order to improve the education of those students gifted in science.
