In this study, the perception and demands on the use of realistic content were analyzed through in-depth interviews with elementary school teachers experienced in using realistic content in science classes. Specifically, the following questions were investigated: (1) What kind of realistic content and how do elementary school teachers use it in science classes? (2) What are the perceptions and difficulties of elementary school teachers regarding the use of realistic content in science classes? (3) What are the needs of elementary school teachers related to the professional development program for the use of realistic content in science classes? The study revealed the following results. First, elementary school teachers mainly used digital textbooks and realistic content provided by the "Science Level Up" site, and the content types could be classified into "exploration type," "visit type," and "production type," according to the purpose of use. Second, elementary school teachers mentioned the educational advantages of using realistic content to help students understand scientific content, induce interest and curiosity, and become immersed in a sense of reality. Several difficulties related to the use of realistic content were mentioned. Among them, the lack of high-quality educational content suitable for science classes and a lack of examples of specific class cases that use realistic content stood out. Thirdly, regarding the development of teacher expertise to use realistic content, elementary school teachers emphasized the need for information on quality realistic content; teacher training centered on specific class cases; instructional models that can be applied by realistic content type; and information on the purchase, use, management, and operation of necessary devices. Reflecting on these research results, implications for more effective use of realistic content in elementary science classes were discussed.

The purpose of this research is to explore types of pedagogical content knowledge (PCK, hereafter) for effective science teaching. In this research, we explored three science teachers' PCK on light, who were effective in teaching the topic with particular students. The data analysis consisted of identifying the three teachers' unique PCK and ways to improve each teaching episode through the teacher meetings. These analyses, which consisted of verbal exchanges among the participants, were identified on the basis of our understanding. Using grounded theory methods, the types of science PCK drawn from this research are: (1) teaching through curriculum reconstruction, (2) teaching to help students build their own explanation models about surrounding nature, (3) teaching for learning the social language of science, (4) teaching to motivate students' learning needs based on relevance of science to students, (5) teaching through lowering students' learning demand by providing scaffolding, (6) teaching based on the teacher's understanding of students, (7) teaching through inquiry with argumentation, (8) teaching through reification of abstract science concepts, and (9) teaching none marginalized science. Common features of science teachers with quality PCK and their professionalism in teaching are discussed.

Textbooks used in Information Society need to use many illustrations and pictures which have positive effect in motivating and triggering students to study. "Pictures mean more than thousands of the word" says that it is significant to use media in class through visual materials. To meet the needs of the times, I examined one of the units, "IV Understanding Humans and Cultural Phenomena", among 7 authorized 'Society Culture' textbooks, so that there are 123 illustrations and 342 pictures that the percentage of them was 35.65% totally in the unit. On the examination of the frequency of using contents in each category, the illustrations are used 59 times (47.96%) in the research activity and the pictures 145 times (42.4%) in the context, which are most frequently used. Also on the examination into the actual states using contents among 'Society Culture' teachers by in-depth interviewing, they often use them when their class starts. And they require more increase in the illustrations than the pictures for easy and clear understanding and need more contents offering in the research activity to help students to study more interesting. Finally, on the result of the analysis of contents used in textbooks, exemplary cases were available to convey enough information without reading the context in the textbook because the proposed illustrations expressed the research activity's subject and the context's subject effectively. Even more, one illustration was able to indicate the sub-unit's subject while also presenting the content to be learned in the unit. However, improper cases included illustrations which are somewhat unrealistic or difficult to understand. Further, there are also some illustrations which are not related to the context. If these points are revised in the future, textbooks would be better.

This study was intended to determine PCK of the middle school science teachers on Mendelian genetics and factors influenced to form their PCKs. Two science teachers with biology major with a teaching experience over 5 years were chosen as the subject. Data were collected by class observation, semi-structured interview, teacher questionnaire survey, Content Representation and Pedagogical and Professional-experience Repertoire. The collected data were analyzed based on Magnusson's PCK for science teaching consisting of five components: (a) the orientation toward teaching science, (b) the knowledge of science curriculum, (c) the knowledge of students' understanding, (d) the knowledge of assessment, and (e) the knowledge and belief in the instructional strategies to teach science. Teachers could have the orientation toward teaching science served as an assisting role to support students' abilities. Both subject teachers seemed to focus on giving lectures. Their efforts to improve students' exploration methods and abilities were not expressed enough in their real classes and they found that students struggled to understand Mendelian genetics. Therefore, they should have explained them in an easier way and worked harder to make their students understood accurately and applied basic and advanced concepts of Mendelian genetics. They found students' preconception and misconception regarding Mendelian genetics and wished to enhance their learning effects by various teaching strategies such as correcting misconception, adding the history of science and simply assessing students' affirmative domains. It was also found that factors influenced to form PCK regarding Mendelian genetics by both teachers were as follows: teacher's personality and endeavor, textbooks and guidance books, schools and their circumstances, teaching experience, experience as a learner, interaction with their colleagues, and university curriculum. Both teachers said that it was important for teachers to make every efforts to give better classes.

This study examined the changes of preservice biology teachers' NOS pedagogical content knowledge through two consecutive science methods courses: NOS understandings; attitudes toward teaching science; difficulties of NOS teaching; NOS teaching strategies; and views of orientation of NOS teaching. During the science methods course I, the preservice teachers engaged in discussions and reflections on what science is and how scientific knowledge has produced, drawing NOS aspects from episodes of history of science, and planning the lessons cooperating NOS instructional objectives. Then the next semester, through the science methods course II, the preservice teachers had a chance of the simulated teaching by adopting NOS teaching and learning activities in the context of the secondary biology context. The preservice teachers, further, reflected on their NOS teaching. The results showed that the preservice teachers constructed the NOS pedagogical content knowledge. They significantly improved their views of NOS and its teaching(p<.05) after the science methods course I, and retained their understanding after the science methods course II(p>.05). The preservice teachers mentioned the difficulties of teaching NOS in the secondary biology context, and further suggested effective NOS teaching methods in their reflective journals.

In this study, we investigated secondary science teachers' internalization of constructivistic science teaching who participated in a collaborative program between teachers and researchers designed by researchers according to constructivist views. The program consisted of lecture, workshop, and small group activities. New trends in science education and framework for science teaching were introduced during lectures, and understanding about the framework were deepened by analyzing school science classes recorded during workshops. In small group activities, participating teachers and researchers cooperated to design science lesson plans using science teaching frameworks. Five secondary science teachers participated in collaborative workshops. Collaborative programs were video-taped. Semi-structured interviews were conducted before and after workshops. All data recorded were transcribed and analyzed. In the process of internalization, participating teachers attended on different parts. Various and discernable factors such as there own background, beliefs, values, and school context produced tensions with or facilitated internalization of constructivistic science teaching. Teaching experiences and student understanding affected teachers' lesson planning activities. Teachers also showed different understandings on inquiry, application, and model from the framework, and they interpret those concepts in the framework based on their prior understanding. They perceived that too much content should be dealt within relatively limited time. Therefore, they tended to separate science class into two parts when developing science lessons: explaining science content by lecture and science laboratory as a constructivistic activity. The results of the study provide meaningful implications to the constructivist teacher education and professional development.

The purpose of this study was to investigate the development and application of strategies using fairy tales in elementary school science. For this study, many fairy tales were searched in terms of various characteristics and educational value of the tales. Five fairy tales were selected and reconstructed to suit the 'mirrors and lenses' unit of 5th graders' school science, and teaching strategies using the fairy tales were developed to be used in six lessons. To investigate the effects of instruction using fairy tales, pre/post tests for scientific attitude were administered. To analyze students' perception of their classes, a simple survey was administered through questionnaires. We found from this study that the students related the fairy tales with their own experiences and took an active part in the class that used them. Also, instruction using fairy tales had positive effects on their scientific attitude. Many students said that the science classes were interesting, and the method using fairy tales encouraged students to study hard as well as helped them to understand the context. It was concluded that instruction using fairy tales was an effective method in terms of enhancing learning motivation, encouraging more inquiries, more opportunities to apply the scientific concept, and more positive scientific attitude. We discussed the strategies using fairy tales for implementation in elementary science classes as well.

The purpose of this study is to examine the problems in the teaching practice of beginning science teachers who participated in the collaborative mentoring program to improve their teaching expertise. The participants were six beginning science teachers and six mentors at middle and high school levels. From each beginning science teacher and mentor teacher, journals, one-to-one mentoring records and transcripts, interviews and questionnaires, and transcripts conducted at the beginning, middle and the end of the mentoring program were collected. Seven aspects of the beginning science teachers' problems in their teaching practice were identified. The result showed that mentee teachers didn't set up specific learning objectives and they organized and presented lesson contents without considering students' proficiency level. Also, they found it hard to prepare for the lessons irrelevant to their major field of study and they tended to use convergent questions more than divergent questions. Mentee teachers tend to give teacher-centered rather than student-centered teaching. Beginning teachers' recognition of their problems in their teaching practice tends to lead changes in their teaching practice. Some of the problems that mentee teachers showed could be overcome if they recognized the problem through the collaborative mentoring program, but if not, it tends to remain throughout mentoring program.This study also highlighted the importance of reflection on beginning science teachers' practice.

This study was to develop and to suggest a lesson plan for the area of‘Human Development and Family Relationship’in home economics for junior high school, based on Thelen’s Group Investigation Model’. Group investigation model by Thelen was developed from the theory that the education with special purpose such as societic knowledge is a method to lesson one’s conflict. This study further developed from three main concepts： inquiry, knowledge and activities of learning groups. This model can be used for any age and any subjects in order to solve the arised problems, rather than to accept pre-organized and pre-decided informations. This study is organized around activities for seeking and practicing the rages of action to create dispersal home. First, one unit ‘Understanding of Family’was chosen that concerns and suitable for group investigation model. Second, From the chosen chapter and problem were analyzed organized. Third, the chosen problem were re-analyzed, then a model lesson for group investigation was proposed.
