This study identified concepts of heat and temperature. The study was conducted by 200 pre-service elementary school teachers at J-university. The questionnaire consisted of 11 multiple choice questions regarding equilibrium of heat, amount of heat, conduction, and radiation. The questions were designed to provide reasons based on answers. The results showed a misconception about the direction of heat transfer. A large percentage of individuals surveyed believed temperature was a measure of heat and also thought heat to be an element. They were not able to distinguish between conceptions of heat and conceptions of temperature.

This study examined how pre-service elementary teachers' perceptions regarding the learning environment (learning focus/ability-meritocracy/cooperative climate) and achievement goals (mastery/performance-approach/performance-avoidance) in science education courses jointly contributed to their science teaching efficacy beliefs (personal science teaching efficacy belief/science teaching outcome expectancy). A path analysis supported a causal model in which the perception of the learning focus influenced the mastery goal, which in turn influenced the personal science teaching efficacy belief and science teaching outcome expectancy. The perception of learning focus also had a direct effect on science teaching outcome expectancy. The perception of ability-meritocracy influenced personal science teaching efficacy belief via the performance-approach (positively) or, conversely, the performance-avoidance goal (negatively). No link .was deduced from the perception of cooperative climate. The educational implications of these findings were also discussed.

Factors and causal structures of pre-service elementary teachers about the critical thinking and the scientific literacy competency were investigated in this study. The third grade university students and the first grade university students in the metropolitan city participated in this study. The factor analysis method and the structural equation modeling method were used for the data analysis, and the following results were obtained. First, the third grade university students and the first grade university students recognized 'inquisitive thinking' factor and 'reflective thinking' factor as factors of the critical thinking, and 'scientific explanation' factor and 'evidence-based conclusion' factor as factors of the scientific literacy competency respectively. Second, the third grade university students showed more the influence from 'reflective thinking' factor to 'scientific explanation' factor and from 'reflective thinking' factor to 'evidence-based conclusion' factor than the first grade university students.

The purpose of this study is to investigate the elementary pre-service teachers' conceptions on 'the freezing point depression' focusing on the survey from a National University of Education. Eighteen pre-service teachers who had completed high school Chemistry II coursework were selected to participate in the study. Participants answered a four question survey to measure their scientific knowledge and conceptions of this phenomenon. Each answer was qualitatively analyzed to determine whether they have 'scientific conceptions' or 'quasi-scientific conceptions' or 'misconceptions'. The results from the study are as follows: First, it was showed that none of the eighteen participants had 'scientific conceptions', six had 'quasi-scientific conceptions' and eight had 'misconceptions' about the caused effect when $CaCl_2$ is scattered on the ice. Second, it was found that three participants had 'scientific conceptions', eight had 'quasi-scientific conceptions' and two had 'misconceptions' for the second survey question. Third, ten out of eighteen participants demonstrated 'scientific conceptions' about the phenomenon of salt water freezing. Fourth, only three of eighteen participants illustrated appropriate 'scientific conceptions' for the fourth survey question. Fifth, of all participants, none answered more than three questions correctly, and only three participants answered any combination of two questions correctly. Based on the findings of this study, five explanatory models were developed. And the models were proposed for pre-service teachers to enhance their understanding of the freezing point depression phenomenon.

In this study, a scratch focused on data visualization was applied to 26 elementary school pre-service teachers to analyze the effect on improvement of creativity. Based on the results of the needs analysis conducted on 60 in-service elementary school teachers, the program using scratches according to the data visualization procedure was developed. With the developed educational program, 26 elementary school pre-service teachers were taught for 42 hours for a total of 4 months. In order to examine whether their creativity was improved, a creativity test was conducted and the effectiveness of the applied program was analyzed through a pre/post comparison tests. As a result of the analysis, it was found that the software education using scratch-oriented data visualization for elementary school pre-service teachers had significant effects on the fluency, sophistication, creativity average, and creativity index among the sub-elements of their creativity.

The purpose of this study was to investigate the process and the effect of pre-service teacher's scaffolding in environmental camp program about global climate change. For this study, developed the environmental camp program based pre-service teacher's scaffolding and applied to 78 $5^{th}$ students. We analyzed the role of pre-service teacher in the process of scaffolding. In the result, the pre-service teachers conducted cognitive scaffolding like as "Focus", "Hint", "Tell or Summarize" and "Technical Help". They carried out the emotional scaffolding like as "Create Cheerful Atmosphere", "Encourage", and "Help in Living". Teaching and learning about global climate change, the theme of the camp, was regarded uncertain and complex. So, pre-service teacher's scaffolding was effective to promote environmental literacy about climate change of primary students (<0.05). The student teachers understanded the characteristics of the children through emotionally close relationships. The primary students were learned easier about global climate change through cognitive and emotional scaffolding. They experienced environmental practice with communal living in camp.

This research analyzed elementary pre-service teachers' perception on the importance and performance of major factors that constitute good instruction, and attempted to find ways to improve pre-service teacher education. A survey was conducted to 157 pre-service teachers who were senior students at a university. The questionnaire consisted of four main areas of good instruction and major factors for each area, and the importance and performance of each factor were answered on a 5-point scale. As the result of the t-test on the difference between importance and performance, significant differences were found between the importance and performance of all 24 factors. In addition, the importance-performance analysis showed that there were 3 factors to be concentrated for the improvement, 9 factors to be kept up because of their good work, 9 factors to have low priority, and 3 factors to avoid excessive effort. Based on the results, the research proposed issues to be considered in organizing and operating the elementary pre-service teacher education program.

In this study, we developed an efficient in-service teachers training program, which could help the professional development of science gifted teachers. The characteristic feature of this in-service training program was to put great emphasis on interaction between fellow teachers. With this program, teachers could share their experiences and informations about gifted education. The program consisted of 4 interaction modules: 'the module of interaction at the pre-planning', 'the module of interaction in the small group', 'the module of interaction at the plan of application', 'the module of interaction at the practical exercise'. In this study, we analyzed the interaction between science gifted education teachers in 'the module of interaction at the pre-planning'. We analyzed the interaction between science gifted education teachers in 'the module of interaction at the pre-planning'. Each teachers got 17.2 correction opinions from peer teachers. They accepted 79.2% opinions among them and refused the other opinions (20.8% opinions). In the analysis of 'program process', the interactions for the improvement about 'the acquirements of knowledge and function' step were 41.9% and the interactions for the improvement about 'plan and exploration' step were 30.5%. In the analysis of 'program domain', the interactions about 'method of teaching and learning' were 41.9%. The interactions about 'program step' were 28.6% and the interactions about 'learning contentsh were 24.8%. With these results, we discussed the features of interaction between science gifted education teachers and proposed the improvement of in-service training program for elementary science gifted teachers.

This study is designed to help pre-service teachers to improve their teaching skills in elementary math class. For this, the consulting program with 5-steps was planned and applied to three elementary pre-service teachers. Each class the teachers performed was analyzed by both Flanders's Interaction Analysis Category System and participant observation. As results of consulting, the common characteristics of three pre-service teachers are shown. Firstly their teaching style is non directive, but they fail to induce their students spontaneously respond. They often ignore or don't use their students' respond they think incorrect to develop the next ideas. Simply saying, their classes are typically teacher-oriented but they are not authoritative. It is proved that consulting program is effective for improving developing non directive teaching skills, but is not much effective decreasing teachers' comment and increasing students' rolls in a math class.

The present study explored whether the implementation of focused activities (intervention programme) can enhance 22 pre-service mathematics teachers' proficiency in solid geometry thinking level as well as change for the better their feelings in this discipline. Over a period of 6 weeks the pre-service teachers participated in activities and diversified experiences with 3D shapes, using illustration aids and actual experience of building 3D shapes in relation to the various spatial thinking levels. The research objectives were to investigate whether the intervention programme, comprising task-oriented activities of solid geometry, enhance mathematics pre-service teachers' mastery of their geometric thinking levels as well as examine their feelings towards this discipline before and after the intervention programme. The findings illustrate that learners' levels of geometric thinking can be promoted, entailing control on higher thinking levels as well as a more positive attitude towards this field.
