The aims of this research are to analyze elementary preservice teacher's conception and causes of their misconceptions on biological reproduction and inheritance. In future, it would be also to provide useful data for the effective teaching-teaming method in the elementary school as well as opportunities to correct their misconceptions, which help elementary preservice teachers have the appropriate scientific conceptions. Thirty kinds of test questions were designed in science curriculum for elementary students and biology textbook for university students in order to develop reproduction and inheritance's concepts. The questionnaire was given to 166 junior students of university of education in a local city. All statistical analysis was performed using SPSS version 10.0 program. The major results are as follows: Among 30 test questions, 2 questions in plants, 5 questions in animals and 2 questions in gene were appeared as misconceptions over $50\%$. The major reason to hold the misconceptions was influenced by 'learning up to now' category. The selection reasons of response were significantly different between scientific conceptions and misconceptions in 10 questions by analysis of variance. The gender also showed statistically significant differences between scientific conception and misconception in 3 questions by $\chi^2$ test. The selection reasons according to gender were significantly different between male and female students in 5 questions. For the reasons in forming misconceptions, they may cause by stereotype, conscious priority, differences of experiences, interest or attention, lack of professional Knowledge, and so on. Therefore, it was concluded that this research may help elementary preservice teachers to reconsider their conception for reproduction and inheritance and to be successful in science instructions fur elementary students.

Korean Ministry of Education Science, and Technology(MEST) has recommended the introduction of mathematics textbooks based on storytelling to improve the teaching and learning of mathematics in school. As part of the mathematics textbooks based on storytelling development, this research has investigated school mathematics teachers' perspectives on mathematics textbooks based on storytelling in order to identify implications for the development and the implementation of it. For the purpose, we have developed survey questionnaire and administered it to 113 high school mathematics teachers. The survey asked the teachers to address their conception of mathematics textbooks based on storytelling, its contribution to school mathematics, challenges and obstacles for the implementation. The survey shows that the mathematics teachers' conception of mathematics textbooks based on storytelling was not clear or limited. Most of them replied that they received information about mathematics textbooks based on storytelling from the materials provided by workshop or materials of school district office. While the teachers heard about that school will implement mathematics textbooks based on storytelling, they rarely had idea of how to use them in class. In the survey, the teachers identified which type of storytelling is effective for which purpose of mathematics education. They also identified the positive effect and the difficulties in the implementation of mathematics textbooks based on storytelling. The mathematics teachers pointed out that textbook is not enough. They urged that the implementation of mathematics textbooks based on storytelling should be integrated into classroom teaching and assessment to make a significant change in the educational practice of mathematics in school. Thus, mathematics teachers need support to implement mathematics textbooks based on storytelling into their teaching practice. Teacher workshop and teacher manuals need to be developed to help teachers understand educational visions and values of mathematics textbooks based on storytelling. These results of the survey would form the worthwhile base information for the development and the implementation of mathematics textbooks based on storytelling.

The purpose of this study was to analyze the elementary teachers' conceptions on the inquiry activity about 'make a fossil model' focusing the 6th, 7th, 2007 revised, and 2009 revised elementary science textbook. This study is intended to find causes of teachers' conceptions and to derive educational implications. We have analyzed questionnaires which were collected from 77 elementary school teachers. It was carried out about comparisons actual fossil with fossil model in each step of the inquiry activity, the lesson goal, the thought for changes of the inquiry activity, the improvement of the inquiry and conception related fossil. Teachers have a general understanding about the contents of the inquiry activity but some of them have partially incorrect understanding. And they emphasize the understanding of the concept on lesson goal. It is necessary to improve inquiry activity reflecting teachers' thinking about the merit and weaknesses. There was not statistically difference in understanding of fossil related concepts according to teachers' career, teaching or training experience. Through this research, there is a need to improve a textbook, a guide book, a teachers' training. So, teachers who have professionalism about science textbook be able to teach students.

The aims of this study are to find the evel of the conception of 'Water Displacement', and to suggest some educational impications from the findings of the study. The result are as follows; Firstly, About 20% of 12 year children among the subjects of this study are aware of the conception of Water Displacement' which is lower than the finding of the study conducted by J. Piaget and Elkind. Secondarly. Most of the subjects in this study are in the transitional level, so this finding suggests that curricular developers should provide the material needed for the educational activities to make children develop the conception of 'Water Displacement'.

Elementary school teachers' understandings about buoyancy were investigated through the questionnaire method. The questionnaire was composed of 4 questions on hydraulic pressure and 8 questions on buoyancy. The questions on buoyancy asked about the correlation of buoyancy with following basic concepts, density of liquid, volume of submerged object and so forth. 295 teachers on the 22 elementary schools in Busan, Yangsan and Gimhae were selected through random sampling method. The results of this study were summarized as follows: On the correlation of the magnitude and direction of hydraulic pressure with the depth of water, a large portion of the respondents had a scientific conception. But on the correlation of hydraulic pressure with density, the relatively small portion of them appeared to have a scientific conception. The respondents, on the whole, had a scientific conception about the correlation of buoyancy with density of liquid. But they seemed to have naive conceptions about the correlation of buoyancy with the volume of a submerged object and with the depth of water, the amount of water in container and the reduced amount of water by the object from container. We found that the respondents were context dependent and tended to search for solutions for the questions of buoyancy using the concept of pressure in the water. From above results, we suggested that in the would-be revised elementary science text book, the contents of pressure in the water should be introduced after the concept of weight in the water was gained.

Many studies on the professional development of science teachers demonstrated that induction teachers' conceptions of teaching science are important factors in developing their professionalism. The present study was conducted to describe in detail the progress of two science induction teachers, June and Mike, towards conceptual change teaching, and to investigate secondary induction science teachers' conceptions of teaching science by analysing their conceptual ecologies. The study was interpretive, using multiple data sources to achieve a triangulation of data. Both June and Mike held strongly positive learning in their views of knowledge and science. Holding positivist views of knowledge and of science is likely to be a major obstacle for anyone coming to understand constructivism and its implications in teaching for conceptual change. This argument resonates in several key ways with the teachers' cases, even though I recognize differences between scenario and teachers, and between teachers themselves.

This study investigated elementary school teachers' understanding of the image formation by converging lens, pinholes camera, mirror and water. In each case teachers were asked to draw the ray diagram to indicate the position of the image. Teachers' ray diagrams were analyzed in accordance with the scientific process of image formation. Results of analysis showed that teacher's conceptions were classified into five levels for each situation. And most of the teachers were in level 3 and level 4 in each case. Because they had difficulties in the appling scientific conception(propagating path of light, diffused reflection from each object point, role of the eye, ray tracing) to finding location of image. Also most of teachers didn't know how to apply the law of reflection and refraction to each situation. The study finally discussed the teacher training program of the optical image.
