The purpose of this study is to analyze the characteristics and specific elements of successful science classes that pre-service elementary school teachers think. For the study, 61 pre-service elementary school teachers (47 females, 14 males) were recruited as research participants. The data used in the study are mutual evaluation papers prepared during class performances by group and individual. The amount of data was a vast amount of qualitative data with a total of 150 pages, and the research results were derived by inductively categorizing this data through qualitative analysis. The summary of the research results is as follows. First, the factors constituting a successful science class were analyzed into 7 categories (14 sub-categories, 33 sub-elements). The elements that make up a successful science class in detail were analyzed as science subject contents, class management, selection of teaching and learning methods and organization of class contents, teaching and learning materials, understanding of students, understanding of teaching situations, and class-related efforts. Second, it was possible to describe the practical classes of pre-service teachers by collecting the details of the elements that make up a successful science class recognized by pre-service teachers. As seen in the above research results, the characteristics and specific elements of successful science classes recognized by pre-service teachers were identified, and based on this, pre-service teachers will be able to develop support for effective science class operation, and continuous analysis should be conducted.

Pre-service teachers have established and developed their own teaching strategies and professional language teaching skills based on their pedagogical and learning experiences. In this regard, it is conceivable that pre-service teachers' feedback may have distinct viewpoints and focuses. Therefore, the purpose of this study is to analyze pre-service teachers' feedback to microteaching demonstrations. Participants in the study were 40 prospective elementary school teachers. They were invited to offer feedback on microteachings video-recorded by their peers. According to the findings, we identified a total of 708 comments. The majority of feedback was categorized as teacher talk(40.1%) , followed by teaching and learning activity (20.9%), interaction (12.6%), teaching materials (11.4%), classroom atmosphere and learning environment (8.9%), lesson flow (3.7%), review and evaluation (1.3%), and introduction and objectives (1.1%). The most frequent types of feedback were the teacher's use of appropriate speaking rate, tone, and intonation. This finding reflects the fact that English teachers realize the importance of the teacher's English proficiency, therefore we suggest that teacher education institutions need raise awareness not just of teachers' English skills but also of their diverse perspectives.

The purpose of this study was to develop science essay writing activities for developing elementary pre-service teacher's scientific thinking ability and scientific emotion and to analyze its effects. For the study, 60 first grade students attending teacher training institutes in the G region of Korea were selected. All 60 elementary pre-service teachers were students who selected a liberal arts lecture related to 'science inquiry'. As a result of the study, we confirmed that the preliminary teacher uses the scientific method of 'induction' in the article related to scientific thinking and the description related to the past time, agency, and purpose of the story is included in the essay related to scientific emotion. In addition, it was confirmed that elementary school teachers' writing ability was improved as the writing was repeated, and that the image of 'science' changed positively in many areas. This study suggests that a various and interesting scientific inquiry activities are needed to improve the science writing skills.

The purpose of this study is to investigate the environmental perceptions of pre-service secondary school teachers about the global environment. The Subjects are 133 pre-service secondary school teachers. As an indicator of environmental perceptions, the modified New Environmental Paradigm (NEP) instrument was used. This modified NEP instrument consists of four dimensions: the negative results of growth and technology, relation of humankind and nature, quality of life, and limits of biosphere. The results of this study suggested that a majority of pre-service secondary teachers held ecological environmental perceptions. They also had a similar environmental perception to education major. However, there were significant differences in environmental perceptions and the variables of education experience on environment-related subjects. Based on the findings of this study, it is recommended that environment-related subjects. Based on the findings of this study, it is recommended that environmental education be a mandatory course in education programs.

This study analyzed the characteristics of prospective teachers' Horizon Content Knowledge(HCK) related to understandings of an inverse function symbol. This study aimed to deduce implications of developing HCK in terms of the means which would enhance mathematics teachers' professional development. In order to achieve the aim, this study identified features of HCK by examining the previous literature on HCK, which has conformed Ball & Bass(2009) and exploring the research in AMT, including Zazkis & Leikin(2010) which has emphasized cultivating AMT through university mathematics education. In addition, a questionnaire was developed regarding the features of HCK and taken by 57 prospective teachers. By analyzing the data obtained from the written responses the participants presented, this study delineated the specific characteristics of the teachers' HCK with regard to an inverse function symbol. Additionally, several issues in the teacher education for improving HCK were discussed, and the results of this research could inspire designing and implementing a teacher education program relevant to HCK.

In this study the description patterns of chemistry textbooks on the boiling point elevation phenomenon and the understanding patterns of high school students, pre-service teachers and chemistry teachers were investigated. High school chemistry II textbooks developed in the 6th and 7th national curricula were analyzed and the conception patterns of subjects on this phenomenon were categorized using a questionnaire developed for this study. The description patterns of science textbooks were classified into three: 'decreasing of surface solvent molecules', 'attraction force between solvent and solute molecules' and 'decreasing of surface solvent molecules and attraction force between solvent and solute molecules'. In the result of the conception analysis, the ratio of 'attraction force between solvent and solute molecules' was high among students, pre-service teachers, and chemistry teachers. There was a propensity that they would like to explain the boiling point elevation in terms of enthalpy rather than entropy, and in order to analyze this propensity, follow-up interviews were carried out.

The purpose of this study is to identify the mediating effect of team efficacy between interpersonal competence and perceived learning in project learning for pre-service early childhood teachers. Based on a literature review, team efficacy and interpersonal competence were identified as variables having an effect on project learning. The data were collected from 172 students who participated in a project learning course offered by a university located in Seoul, Korea, and were analyzed by Baron & Kenny's (1986) framework. As a result, team efficacy was found to act as a partial mediator between the two variables, understanding of and consideration for other people and perceived learning. This study suggests that team efficacy and understanding of and consideration for other people should be facilitated in project learning courses. The possibility that some teaching strategies could enhance the project learning effect for learners and pre-service teachers is discussed.

This study intended to analyze pre-service elementary teachers' perceptions of teacher knowledge based on the Technological, Pedagogical, and Content Knowledge (TPACK) framework. Seventy-four pre-service elementary teachers who were enrolled at an University of Education located in mid-continent of Korea participated in a survey. Results of the survey was analyzed using Importance-Performance Analysis (IPA) method. It was found that perception of importance was significantly higher than that of performance at all seven domains of the TPACK. IPA matrix extracted from the survey indicates that Technological Content Knowledge (TCK), Technological Pedagogical Knowledge (TPK), and TPACK which are related to technology especially need to develop. Results of this study also show the necessity to support pre-service teachers so that they can have opportunities to develop and use technology-related knowledge and skills. This study especially implies that technological knowledge needs to be integrated with content and pedagogical knowledge when implementing curriculum and educational programs for pre-servie elementary teachers.

This study is an investigation regarding the understanding of the nature of science among pre-service science teachers majoring in science education. We interviewed 22 senior students in science education who finished their internship courses. Students were interviewed individually for approximately 20 minutes each. Data from semi-structured interview were audio-recorded and transcribed for the analysis. Findings indicated that participants held more complete understanding of the nature of scientific knowledge than the nature of scientific enterprise. Their understandings of the nature of scientific method was that hypothetical-deductive method is more scientific than descriptive-narrative method and there is a single stepwise scientific method to solve problems. These results showed that they have a narrow view of the nature of science. Thus, teacher education programs need to integrate the understanding of the nature of science throughout.

This study examined the process, difficulties and understanding of making teaching materials by investigating the pre-service early childhood teachers' experience of making such materials. The results of the study would help in the design direction and methods of education for pre-service teachers in how to make materials. A total of 30 university students, who took the course of 'Early Childhood Educational Materials and Research Method' in B university, participated in the study. At the exploration stage, the pre-service teachers utilized the teacher guidance of Nuri curriculum, major books, internet materials, and their observation experiences in kindergartens. At the planning stage, they considered chiefly the children's interest and level, explored materials sufficiently, and selected the production method carefully. At the production stage, they performed basic hard work to prevent rework and tended to stick to the basics beyond their initial ambition as the work progressed. The difficulties that they faced, feeling pressured, were making materials based on their imagination without experiencing much from the infants, feeling embarrassed when things did not progress as planned, and feeling a sense of loss when comparing with other friends. Through these difficulties, the importance of precise planning, executing the process thoroughly, and repeatedly checking and reviewing the entire process of making textbooks and materials were realized. In addition, there is a need to search for a better development direction for the effective development of teaching textbooks and materials.
