The purpose of this research is to minimize the learning deficiency on science subject in changeover from the 7th education curriculum to the next curriculum which was noticed in 2007. We investigated the contents overlapped or omitted in science contents organization between the two curriculums; moved contents to upper or lower grade, deleted contents, enlarged contents and reduced contents. Also we found that the deficiency will be occurred for the students who entered school in 2006 and 2007 in elementary school. To minimize the learning deficiency in the changeover, we must consider the following points. (1) We need to promote the teachers' comprehension about the learning deficiency and supplementary instruction through the teacher training program before carrying out the next curriculum. (2) We must add the measures minimizing the learning deficiency to the teachers' guide and resources which are used in encouragement of learning and teachers' training. (3) We must develop the instructing materials to supplement the learning deficiency for the students who entered school in 2006 and 2007. As practicing above points, we will be able to reduce time loss in studying and teaching the same contents and to supplement the omitted contents.

This study details a researcher's self-study journey in advancing from a computational thinking (CT) novice to an expert. The researcher went through a four-stage process, with a preliminary literature review preceding the four stages. From the literature review, the computational thinking analysis (CT_AT) tool was developed for use in stage one to analyze science, technology, engineering, art, and mathematic (STEAM) modules. Although no discernable patterns were found in analyzing the five science and five engineering-based modules, the analysis revealed which CT practices were missing or weakly exposed. In stage two activities were suggested to promote these missing or weakly exposed practices. Stage three required the researcher to develop his own STEAM module from the viewpoint of exposing students to CT. The fourth stage was to validate the CT_AT through interviews with pre-service and in-service teachers. These interviews led to changes in the CT_AT tool and, as a result, the researcher produced a guidebook that could be used by teachers in their own CT studies. This guidebook can be used by teachers to develop and become competent in CT skills.

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.

This study aims to determine the implications of the efficient and effective implementation of science core competency (ScC) education by examining the state of science core competencies derived from the 2015 revised elementary school science curriculum and analyzing teachers' and students' perceptions. To this end, this paper investigated the reality of reflecting the science core competencies of science textbooks in a group of third and fourth graders from seven elementary schools who passed the test. In addition, in-depth interviews were conducted with four elementary school teachers who participated in qualification textbook selection, and 156 elementary school students were surveyed to determine their perceptions of science core competencies. Findings showed that, first, 1,586 science core competencies were reflected throughout the textbooks, with an average of 227 per textbook and biology being the most salient area. Second, teachers did not understand the difference between previous inquiry activities in textbooks and ScC education. Third, no statistically significant differences were observed in the perceptions of male and female students on science core competencies, the highest average of perceptions being those of scientific thinking ability. From these results, this study concluded that for ScC education to be realized as a curriculum, textbooks must be organized according to the purpose of core competency education, implementing practical changes, and efforts must be directed toward changing the perceptions of individuals who deliver education.

The purpose of this study was to explore the manners in which models are used in secondary science classrooms. A total of thirteen video-recordings of science lessons dealing with the domains of atmospheric and oceanic earth sciences and their verbatim transcripts were analysed both quantitatively and qualitatively. Interviews with three inservice science teachers were also conducted. Six interrelated assertions were generated as the result of the study: 1) The most frequently used models in secondary earth science classrooms include two-dimensional pictorial, symbolic, iconic, and diagrammatic ones; 2) Science teachers employ models as a mode of representation to make the subject matter available to students; 3) In earth science classrooms, teachers use typical forms of models in intensive manners; 4) Students themselves deal with models on a few occasions, but they just follow similar procedures with the same models; 5) Teachers talk rarely about the nature of scientific models and provide few opportunities for students to think about it; and, 6) Teachers in practice think that the value of using models should be appraised in consideration of the pedagogical intentions of the teacher. Implications for science education and science education research were discussed.

The purpose of this research is to investigate ways to improve science teacher education in order to subsequently develop students' key competencies. Since the OECD redefined key competencies as 'what people should know and be able to do in order to lead a successful life in a well-functioning society, many countries have emphasized competency-based curriculum. In this research, we collected and analyzed foreign and domestic classroom cases that have implemented competency-based curriculum in science teaching. Through open-ended interviews with the teachers and principals we explored ways to improve science teacher education to develop students' key competencies. According to the results, the competency-based curriculum necessitates a shift in teachers' roles including teachers as role models for their students, multifaceted roles of teachers, and teachers as researchers. In light of the teacher's community, teachers need to form a professional learning community, increase practice-based professional development opportunities, build the teacher's knowledge base, put various experts into the classroom, and build a partnership with the local community and other experts. In the conclusion section, we also discussed institutional and political supports necessary for the competency based education.

In this study, KTOP (Korean Teaching Observation Protocol) was applied to teaching practicum for improving pre-service teachers' science teaching. To do this, four pre-service teachers and supervisor teacher observed and analyzed the lessons using the KTOP, and tried to improve he succeeding lessons through collaboration activities. As a result, the pre-service teachers conducted the collaboration activities based on the lesson analysis using the KTOP, therefore it was concluded that the KTOP took a practical role of guidance for improving pre-service science teachers' teaching. And it was found that the collaboration activities using the KTOP helped the improvement of the succeeding lesson, however, more iterative application is necessary for more effective improvement of teaching. Based on the analysis of questionnaire, observation, and interview, it was found that pre-service teachers need to be confident about the use of the KTOP and strive to become a student-centered lesson. And, the KTOP needs to be modified by reducing the number of items and as a more convenient form. Finally, it was inferred that we need to give an effort to help students recognize that learning should be self-directed.

In most classrooms, teachers talk more than students. Teachers have been thought to be knowledge-donors and students have been thought to be knowledge-acceptors, so teacher-talks were thought to be more important than student-talks. But student-talks are very important to the students: not only to the students who speak out their opinions or answer to the questions given to them, but also to the others who say nothing in the class. Many students in Korea are not so fond of speaking out something to all the class, so some teachers are using a strategy: to say something as if he for she) is a student in the classroom. What teachers talk are not the words of the teacher-talks. They are only talked by the teachers, but they function like student-talks. To study this type of talks are needed to help both teachers and students but there are not much research about this. So in this paper we a) name it Pseudo Student Talk (PST), b) define it as 'a kind of talks that are not talked by students of the class but its functions are very similar to the student-talks', c) classify PST in 'EBS 2005 science class for 7th grade' according to types of student talks (categorized by Lemke, 1990), and d) show the usage of each kind of PST.

The purpose of this study is to analyze verbal interaction between teachers and students in order to collect qualitative data on the characteristics of the interaction to enhance teaching efficacy. Total of 12 classes of eight science teachers were observed and were interviewed. The classes were video taped and all the verbal interactions were transcribed. The transcribed content and interviews were further analyzed to draw any conclusions on the verbal interaction between teachers and students. Analysis criteria for the data on the class and interview were developed based on the literature review and applied to analyze the collected content. The analyzed data showed that verbal interactions composed of confirmation questions for memorization, students' short responses and teacher's immediate feedbacks. The results of the study also suggested that there needs to be further studies on the interactional techniques for teacher in utilizing the class materials and activities. The teachers should acknowledge the importance of the questions and feedbacks of teachers for students to stimulate their sound learning through literatures.
