This study analyzed the information-seeking behavior of preservice science teachers by observing the process of seeking information needed in a Socioscientific issues (SSI) debate class. Twenty-four fourth-year preservice science teachers participated in the study, and the SSI debate was conducted on the topic of biofuels. The results of the study revealed that preservice teachers go through the process of 'Searching', 'Reviewing', 'Interpreting', and 'Evaluating and Reorganizing' stages when seeking information. The searching stage is divided into identifying topics, role division, and standard setting for a search. The reviewing stage is divided into reviewing sources and reviewing contents. The interpreting stage is divided into interpreting an information and interpreting information from an integrating aspect. In addition, the evaluating and reorganizing stage is divided into evaluating information and reorganizing information. It was found that preservice teachers have difficulty reviewing information and interpreting multiple sources of information in an integrated aspect. Also, it was found that evaluating information activity among preservice teachers' information-seeking behavior affects the level of argumentation in discussions.

This study is an action research aimed at improving the instruction of a teacher educator who teaches science teaching methods to elementary preservice teachers. After identifying the cause of their low levels of curiosity and interest in physics, teaching plans addressing this problem were explored, applied to classes, and reflected upon. Through this process, ways to improve teaching practice in science classes for elementary preservice teachers and pique their scientific curiosity and interest were proposed. A spiral implementation structure that repeats implementation and reflection a total of three times was designed for the prospective preservice teachers who participated in elementary science textbook research physics classes. Self-reports, student participation data, and results from both peer and self-evaluations were collected and analyzed. The reasons for the preservice teachers' low levels of curiosity and interest in science were identified as their inability to recognize and express information gaps and their low levels of willingness to resolve this. Practice expressing information gaps, raising the level of knowledge to be able to recognize information gaps, and a strategy to have the will to resolve information gaps were introduced into the class. To the extent that changes can be made by improving unit classes, elementary preservice teachers can express their curiosity and interest in science through this process.

This study investigated elementary preservice teachers' conceptions of a generating line, an ambiguous concept in school mathematics. The preservice teachers' conceptions of a generating line can be classified into four types: (a) only cones have generating lines, (b) only cones and cylinders have generating lines, (c) solids of revolution have generating lines, (d) straight lines on the lateral surface are generating lines. 22.1% of all preservice teachers believed that only cones have generating lines, and most of them followed the definition of a generating line presented in elementary mathematics textbooks. The conception that only cones and cylinders have generating lines was the least investigated. However, since there were instances where generating lines were defined with the use of a director curve, it became important to explore topics more thoroughly, such as generating lines of a truncated cone. 27.9% of all preservice teachers believed that solids of revolution have generating lines. This conception was marked by differing opinions on whether spheres also have generating lines. The conception that straight lines on the lateral surface are generating lines was the most frequently investigated. This conception differs from the traditional view in school mathematics because it suggests using a director curve to define generating lines. Based on these analysis results, the researcher developed specific teaching methods that considered both subject matter knowledge and pedagogical content knowledge for preservice teachers. In addition, the researcher proposed a consensus definition of a generating line in mathematics education.

Constructivism is defined in a variety of ways (e.g., constructivist research paradigm, sociological constructivism, and philosophical constructivism) and applied in vastly different contexts. Among the various usages and interpretations of constructivism, one is educational constructivism that embodies an epistemological view of knowledge and learning that is an alternative to naive empiricism or classical behaviorism. To represent the full range of stances taken by educational constructivists, three versions of educational constructivism were considered in this study: individual constructivism originating in the work of Piaget, the radical version of constructivism associated with von Glasersfeld, and the social constructivism of Vygotsky. I investigated preservice teachers' meaning construction about constructivist epistemology as they went through their preservice teacher education program using in-depth interviews. This preservice teacher education program employs constructivist aspects of teacher education and generates applications of constructivism to the practice of teaching. Features of preservice teachers' internalized meanings of educational constructivism include: (1)traditional pedagogy as the default, (2) Literal interpretation of constructivism, (3) Individual constructivism as conceptual change learning, (4) Radical constructivism as a strong individualistic philosophy, (5) Social constructivism as being too ideal to be practical. A compilation of the teachers' own statements about how to implement conceptual change learning and their projected role as constructivist teacher is also provided.

The quality of science teachers is one of the most important factors to improve the science education in secondary schools. In this study the current status of preservice education of secondary science teachers was surveyed and the directions for the improvement were suggested as follows: 1. The purposes of departments of science education have to be partially revised to include other education programs related to science education than preservice training courses of science teachers. 2. Training courses of integrated science teacher should be organized differently from those of physics, chemistry, biology or earth science teachers because their requirements are different. 3. Strict standards of curricula for training science teacher have to be established and applied practically. 4. The curricula of departments of science education have to reflect the contents and the changes of secondary science education. 5. More credits to subjects on the science education, the nature of science, and the laboratory experiments should be taken in the preservice courses of science teachers. 6. Professors at the department of science education have to use various methods to teach inquiry lab and evaluation techniques so that students can experience them at the training courses. 7. The number of professors majoring in science education at the department of sciece education should be increased. 8. Enough research funds have to be supported to activate the researches in science education.

The study was designed to describe the pre service teachers' development of their TPCK throughout the teacher preparation program that integrated technology throughout the program and how they succeeded in teaching with technology in the actual classroom during student teaching. Multiple data sources were used to obtain information toward answering the research questions. Overall, the emphasis of the teacher preparation program in this study in helping preservice teachers to acquire TPCK transformed the preservice teachers' understanding described by the four components of TPCK. However, the diversity of beliefs, teaching, and technology background affected their understanding and development of TPCK throughout the program.

The purpose of this study was to examine the impact of the emotional intelligence of preservice early childhood teachers on their self-concept and self-efficacy in an attempt to provide some information on the development of the emotional intelligence of preservice early childhood teachers. The subjects in this study were the freshmen, sophomores and juniors who were in the departments of early childhood education in private colleges and universities in Chungcheong, Kyonggi, Seoul, in Korea. After a survey was conducted, the following findings were given: First, the juniors had the best self-concept of the others, and the freshmen were ahead of the others in self-efficacy. The university students had a better self-concept than the college students. Second, emotional intelligence had a statistically significant positive correlation to self-concept and self-efficacy. Third, all the sub-factors of emotional intelligence exerted a statistically significant positive influence on self-concept. Among the sub-factors of emotional intelligence, emotional regulation and emotional utilization exerted a statistically significant positive influence on self-efficacy. The findings of the study illustrated that the preservice early childhood teachers had a better self-concept and a better self-efficacy when they were better at emotional intelligence.
