A flipped learning class was held in an attempt to overcome the limits of lecture-type classes in pre-service science teacher training and to provide a student-oriented education suitable for digital native generation. The principles of teaching-learning in flipped learning were applied to the general ADDIE model to design the class; learning materials were developed accordingly. The developed flipped learning materials and class design were verified for their validity using an expert panel's Delphi method and validity test, in which the validity was verified with 0.75 CVR. The developed flipped learning materials were applied to the theory of science education and the instructional effectiveness was analyzed. The results suggest that the students' motivation to study, interest, and confidence in learning increased; however, their satisfaction in class decreased by 30% as compared to the lecture-type class and their self-confidence in the improvement of their academic achievement was not sufficient. In order for a flipped learning class to be successful, the class should be small in size, which would ensure appropriate teacher-student communication and individualized learning; also, the students' burden of learning should be reduced and accessibility to video materials for pre-class learning should be reinforced.

This study aimed to analyze the appropriateness of chemistry teaching-learning programs for the gifted in science in middle school gifted classes and to propose improvements. For this study, 5 chemistry teaching-learning 4-6 hour programs developed for science gifted classes by Korea Education Development Institute (KEDI) and 3 chemistry teaching-learning programs developed for science gifted classes by three middle schools in K province were selected. A standard model for gifted education programs was used as tool for analyzing the program targets, program contents, teaching-learning methods, and assessment items. The results showed that all chemistry teaching-learning programs for the gifted in science presented well attainable objectives in the program targets. However, most program targets did not offer differentiated objectives from the general education. Program contents of KEDI stresses intensified education, and also presented a high ratio of sub-elements of creativity, which can enhance gifted creativity. On the other hand, program contents developed by three middle schools focused on acceleration in advancement, and presented low ratio of creativity sub-elements, which could be insufficient in enhancing gifted creativity. Differentiated and personalized, integrated science and interscience, updated research contents were hardly found in programs developed by KEDI and three middle schools. However, teaching-learning methods were composed to fit the learning objectives in the teaching process and the procedures, and were made to self-directed learning. There were no assessment for the feedback after class. Therefore, teaching-learning programs for the gifted in science should be developed further in order to fulfill the objectives of gifted education and gifted characteristics. Also, it is necessary to construct infrastructure to carry out the developed teaching-learning programs.

The purpose of this study is to extract the factors that compose the image of science teacher desired by elementary school students in inquiry-based instruction and analyze the structural associations between them. Factors that compose the image of science teacher desired by elementary school students in inquiry-based instruction were extracted through exploratory factor analysis (EFA). Based on the findings of EFA, the questionnaire has been further analyzed using confirmatory factor analysis (CFA). In addition, based on the factor structure identified through factor analysis, we comprehensively analyzed the image of science teacher desired by elementary school students in inquiry-based instruction. As a result of EFA, five factors were identified which compose the image of science teacher desired by elementary school students in inquiry-based instruction: namely, teaching strategy, assessment strategy, prior guidance, understanding students, learning development. The CFA results showed a relatively strong correlation between teaching strategy and learning development, teaching strategy and understanding students. As a result of a comprehensive review of students' perception of the image of science teachers in inquiry-based instruction based on the extracted factor structure, students perceived that it is important for science teachers to run inquiry-based instruction by reflecting their understanding of students. Students also perceived importantly that science teachers run inquiry-based instruction using effective teaching strategies and proper evaluation strategies.

Teaching-learning activities in a school class is influenced by the development of a information science in the 21 century. Recently, the instruction in a school class use a multimedia teaching-learning contents chiefly. A great number of teachers don't recognize a foundation of the effects on teaching-learning contents utilizing multimedia. In this paper, I propose to analyze and verify the foundation of effects on cognitive psychology of multimedia teaching-learning contents. The principal method of this study is to synthesize and analyze researches of scholars or literature study largely. In this paper, the foundations of effects on multimedia teaching-learning contents are following: the dual encoding of information process, the skill on direction and speed-regulation of learning, and the others educational strength. The theoretical conviction in multimedia teaching-learning contents is operated as the confidence of education contents & media utilized by teachers and learners, and is anticipated as the growth of the quantitative and qualitative learning activities.

Teachers are the most important factor contributing to determining the quality of education. Therefore, the quality of teachers should be improved to enhance the quality of education. Teacher's competencies are defined as the skills required for teaching profession, that is, the ability to perform not only in teaching activities, but also in guidance and class management. The purpose of this study is to analyze the competencies of science teachers that elementary, middle and high school students want. To this end, 332 elementary, middle and high school students were asked to describe their preferred science teacher's competencies and avoiding science teacher's competencies as an open questionnaire. The resulting concepts were analyzed by semantic network analysis (SNA). The results of this study are as follows: 1) The competencies of science teachers that students prefer varied. This suggests that most students think positively about science teachers. In addition, it is possible to show students the positive or preferred competencies of teachers in various ways. 2) The students wanted teachers to explain the theories and concepts related to scientific phenomena through experiments. They also preferred hands-on activities and experience in science class. 3) The students put emphasis on the class-related contents in the competencies of science teachers. Accordingly, the image of science teachers and science itself should be enhanced through the improvement of science teaching methods and positive attitudes toward students. It is expected that further research on the image according to specific teaching methods of science teachers will be conducted based on the findings of this study.
