This study aims to develop biology teachers' education program based on argumentation activity about core concepts of evolution and to analyze the characteristics of core concepts of evolution learned during the program. The eight core concepts of evolution in this study were variation, heritability of variation, competition, natural selection, adaptation, differential reproductive rate of individuals, changes in genetic pool within a population, and macroevolution. The performances of teachers participating in the program were compared before and after argumentation activities; consisting of seven sessions on the eight core concepts of evolution. The process of the program was specially designed by learning cycle model for teacher education, consisting of seven phases: identification of the task, production of a tentative argument, small group's written argument, share arguments with the other groups, reflective discussion, final written argument, and organization by an instructor. Participants in the study were two pre-service biology teachers and four in-service biology teachers. The results suggest that biology teachers reduced the teleological explanation for biological evolution and improve its adequacy after the intervention. Teachers lacked the opportunity to discuss variation, heritability of variation, competition, and macroevolution because science textbooks lack information on the concepts of biological evolution. The results of this study suggest that because the argumentation program developed for teachers helps to improve understanding the concepts of evolution and to reduce inadequate conceptions in biology, teacher education programs using argumentation activity and eight core concepts of evolution will play a role for efficient evolution education for biology teachers.

This study aims to develop the NABI program, which can be applied to science education in school, to realize 'Science Education through Nature' for today's students. The first NABI program was developed based on the viewpoints of education and teaching methods of Nature-Study, and it was revised as the second NABI program through experts' workshop. The second NABI program was applied to 24 third-grade students of an elementary school. The possibility of applying the program to school science education was explored through the analysis of students' qualitative data, along with surveys that were completed by 24 students and 79 current teachers. As a result of applying the program, students were curious about and communed with nature. The program could also realize the learner-centered education and integration of subjects, science with literature and art. The students were interested and wanted to continually participate in the NABI program. The teachers' evaluation of the program deduced that the relationship between the program presenting Nature-Study ideologies could be applied to science education in school. In conclusion, it was found that the NABI program was well reflected in the scope of the Nature-Study, and it can be applied to science education in school. The NABI program proceeds in nine steps: 'Accepting - Choosing - Selecting the common subject - Ice Breaking - Making relationship - Observing - Scaffolding - Expressing - Sharing'. The NABI program is a good way to realize the essence of science education, 'Science Education through Nature', for today's students.

A Calculator-Based Laboratory (CBL) system was introduced to science teachers and their perceptions to its classroom application was assessed. A CBL survey instrument was responded by 54 middle and high school science teachers who undertook a three-hour workshop of science experiments with CBL system. There were significant differences in teachers perceptions to CBL system among gender, school level, school location, teacher's degree, and years of teaching in terms of learning CBL system, applicability of CBL system for science classrooms, and effects on science achievement. Male teachers showed significantly (p<.05) higher agreement to learning of CBL system and applicability for science classrooms than female teachers. Compared to middle school teachers, high school teachers showed significantly (p<.05) high interests in CBL applicability for science classrooms and perceptions that there will be an increase of science achievement. Teachers with 4-8 years of teaching experience also showed significantly (p<.05) higher interest toward learning CBL system and its applicability. It was concluded that science teachers perceived CBL system as a promising science teaching method in Korean middle and high schools. However, a science teacher inservice training program for CBL system should be developed in consideration of gender, school level, school location, and years of teaching.

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.

In this study, we propose a way to improve science teacher expertise through infographics creation teacher training program by analyzing the infographics types focusing on the Earth Science subject of the 2015 revised curriculum, and inspecting the teachers' utilization of graphic tools. The data visualization characteristics of Earth Science textbooks were analyzed, the execution results of the infographics creation teacher training program were presented, and a survey on science teachers' change in perception and competency of infographics. As a result of the Earth Science textbook analysis, diagram-type, map-type, and comparative analysis-type infographics were frequently used, and were mainly presented as text-assisted-type infographics. The infographics creation teacher training program was conducted five times for 112 science teachers to create the complete, text-assisted, incomplete, and gradient-type infographics. Incomplete infographics for development of evaluation questions were most needed. Although many science teachers recognize the importance of infographics, they lacked the competency to create high-quality infographics because there were no training opportunities for infographics creation. After completing the training, 74.1% of teachers felt that the quality of developments of supplementary textbooks and evaluation questions had improved, and answered that it was helpful in re-educating knowledge and improving teaching-learning methods. Based on the research results, ways to improve science teacher expertise through infographics creation teacher training program were suggested.

The purpose of this study is to investigate pre-service science teachers' difficulties in the 'inquiry mentoring' program, which was developed to improve pre-service science teachers' inquiry teaching ability. For this study, I developed the 'inquiry mentoring' program in which pre-service science teachers taught high school students. This program was adapted for 2.5 months, and 45 pre-service science teachers participated and taught 44 high school students. During this program, pre-service science teachers kept 'mentor diaries' and wrote 'mentoring reports' at the end of the program. Interviews were conducted with all pre-service science teachers. Results are as follows: first, pre-service science teachers thought that the difficulties in inquiry mentoring resulted from their inadequacy (mentor factor) than students' inadequacy (mentee factor). Second, pre-service science teachers perceived their lack of cognitive ability, inquiry ability and teaching ability as a mentor factor. Third, pre-service science teachers thought that they had difficulties in students' differences and lack of activity as a mentee factor. Fourth, they described difficulties caused by emotional distance as well as physical distance as an interaction factor. They also mentioned the difficulties related to teaching range and online interaction. Fifth, pre-service science teachers expressed a sense of frustration with the inquiry environment. Additionally, some implications were discussed for pre-service science teacher education through the 'inquiry mentoring' program.

The purpose of this study is to investigate the effect of science-centered convergence class program using realistic contents such as virtual reality and augmented reality on class satisfaction, scientific attitudes and the perception of the gifted students in middle school. After developing the convergence class program including realistic contents using smart devices, we applied it to the gifted students. We analyzed the class satisfaction, scientific attitude and perception of the gifted students through questionnaires. In addition, a survey was conducted on the pre-teachers to investigate and analyze the class satisfaction, scientific attitude of the science class program to students and the perception of science classes using realistic contents. As a result, both students and pre-teachers were positively aware of class satisfaction by science class program using realistic contents. In particular, it was positive in that the class can induce learning motivation and interest. On the other hand, it was pointed out that the low-quality App and lack of infra for smart devices were disadvantages. In addition, pre-teachers lack confidence and information about class using the realistic contents, but they recognize the need of classes using realistic contents for students and education for pre-teachers. Based on this, it obtained suggestions on the preparation of facilities and equipment in schools for future education, development of contents that can be used for convergence class, development of programs and teaching·learning materials using realistic contents, and education for pre-teachers.

In this study, we implemented an education program to improve the responsive teaching ability of pre-service science teachers, and analyzed the responsive teaching practices revealed during the program process. Through this, we derived the types and characteristics of responsive teaching practice, identified factors that made it difficult for pre-service teachers to practice, and obtained empirical data on under what conditions the responsive teaching capacity of pre-service teachers was developed. For this purpose, a practice-based teacher education program was designed and carried out for 14 pre-service teachers who had no experience in responsive teaching. The program consists of four steps; observation of class, practice through rehearsal, application in practicum, and post-reflection on educational practice. In particular, qualitative analysis was conducted on the types of responsive teaching and their detrimental factors revealed during application in practicum. As a result of the analysis, four types were derived; discriminator type, communicator type, guide type, and facilitator type. Each type was identified as having a common responsive teaching step element. The education program implemented in this study was effective for pre-service teachers to recognize the importance of student-participation class and the educational effect of responsive teaching. However, three barriers that prevented pre-service teachers from responsive teaching practice were also analyzed. First was the pressure to achieve specific learning goals within a given class time. Second was the rigid belief of the fixed curriculum. Third was the obsession that the teacher should lead the class. Based on these results, it was suggested that in order to improve the responsive teaching ability of pre-service teachers, it is necessary to support the recognition of breaking out of the thinking the time constraint, the flexibility of the curriculum, and the role of teacher as a class supporter.
