Pre-service teachers' understandings on magnet was investigated through the questionnaire method. The questionnaire was composed of 17 questions about the strength of magnet, the magnetized object and the direction of magnetic field around magnet. In this investigation study, 225 pre-service teachers were selected through random sampling method, who were sophomores in a National University of Education. The formation rate of the scientific conceptions on the strength of magnet was 30.3% and that on the direction of magnetic field around magnet was 53.9%. The average formation rate of scientific conception of all questions on magnet was 44.13%, which doesn't seem to be high as expected. It shows that many of subjects of the questionnaire don't understand fully the concept of moleclar magnet model and the superposition effects of magnetic field around magnet. The formation rate of the scientific conception on magnet of females who took courses in sciences in high school were higher than that of females who took courses in arts in high school, which had meaningful difference (p<.05).

After pre-service teachers become teachers, traditional patterns of classroom discourse which they had experienced as students affect their classroom discourse implicitly. For this reason, it is needed to get a new insight for evaluating and reflecting a teacher's classroom discourse. In this study, I analyzed the information flow of science classes of pre-service elementary school teachers. The finding showed that teachers' organizational skills for students' information made advanced science classes by maintaining discourse cohesions. And the findings also showed a way how to analyze, evaluate or reflect science classroom discourse. This trial could contribute to find out the characteristics of teachers' science classroom discourse and show the directions to them how to change their classes beyond impressionable evaluations for their science classes.

The purpose of this study was to investigate the nature of pre-service elementary teachers' metaphors on mathematics textbooks. Their metaphors describe individual and collective patterns of thinking and action on mathematics teaching and learning. To analyze their metaphors, qualitative analysis method based on Lakoff and Johnson's theory of metaphor (1980) was adopted. Metaphors on mathematics textbooks were elicited from 161 pre-service elementary school teachers through writing prompts. The writing prompt responses revealed three types and thirteen categories: As Type I, there were (1) 'Principles', (2) 'Summary', (3) 'Manual', (4) 'Encyclopedia', (5) 'Code', (6) 'Guidelines', and (7) 'Example'. As TypeII, there were (9) 'Assistant', (10) 'Friend', (11) 'Scale', and (12) 'Ongoing'. As TypeIII, there was (13) 'Trap'. Among these categories, 'Guidelines', 'Assistant', and 'Ongoing' were the most frequently revealed. These results indicate that the relations of mathematics curriculum, textbooks, and classrooms are not a unilateral way but should communicate with each other.

According to instruction of standard-based assessment system, teachers with higher level of competence in student assessment are required. The purpose of this study is to offer the basic data to enhance pre-service physics teachers' competency in student assessment. 17 pre-service physics teachers, who are sophomore in department of physics education, participated in the study for a whole semester. To do this, we gave the assignment of multiple choice question construction in physics conceptest for formative assessment to pre-service teachers and observed review questions constructed by them. We also analyzed multiple choice questions of 17 pre-service teachers. They had 5 classes for the review process of the question and improved their questions through it. 16 of 17 pre-service teachers completed test design. Our results show that pre-service teachers had a little low competence in test design for classroom assessment. In addition to, constructing and revising questions, almost of them didn't have various perspectives and didn't consider to get information about the pre-conceptions of students. These findings indicate that they have difficulties with constructing multiple choice question and more specific plan needs to enhance the overall student-assessment competency levels of pre-service teachers for successful settlement of the standard-based assessment system.

The purpose this research was to develop the practicum-affiliated coursework for pre-service chemistry teachers to enhance their instructional professionalism. The researchers developed the syllabus and the materials of the practicum-affiliated coursework and opened the class 'Practice of Chemistry Lesson' for the pre-service chemistry teachers who were expected to participate in the practicum. Semi-constructed individual interviews revealed that pre-service chemistry teachers thought the developed coursework, which linked science education theory and practice, helped them to develop educational connoisseurship about good science class and to be prepared practically to the practicum, and as the result, they could enhance their teaching ability. The result identified that the reconstruction of the practicum experience through the process of 5 steps of the curriculum could develop the instructional professionalism of pre-service chemistry teachers.

The purpose of this study was to analyze the pre-service teachers' perception for education paradigm and teacher's teaching competency in the fourth industrial revolution era. For this study 53 pre-service teachers participated in the discussion instruction during one semester. The study result was to analyze the discussion reports of pre-service students using the grounded theory approach. As a result, the pre-service students responded that the school needs to change the learner-centered education and assessment method in the fourth industrial revolution era. Secondly, the result of the teachers' teaching competencies was the integrated curriculum reconstruction, information processing, empathy and understanding, creative teaching and instructional design, collaboration and communication. This study is expected to contribute to the change of education paradigm for pre-service teachers in the fourth industrial revolution era.

Frequently, pre-service elementary teachers are asked to write reflective journals on their teaching during teacher education program. However, writing reflective journals can not guarantee pre-service teachers to learn from their experience. In this study, 44 reflective journals of pre-service elementary teachers on their science teaching were analyzed in terms of 'productive reflection', a concept suggested by Davis (2006). Productive reflection may help teachers' effective learning by considering interrelationships among aspects of teaching including learners and learning, subject matter knowledge, assessment, and instruction. The result showed what aspects of teaching were included, emphasized, and integrated in the pre-service elementary teachers' reflective journals. Implications for teacher education would be discussed.

The purpose of this study is to assess pre-service elementary teacher's conceptions of environmental issues. 141 pre-service elementary teachers from local college participated in this study. We discovered that most of participants understood the possibility of technological abuse that could lead to environmental destruction. They also well understood the crisis of the Earth's ecosystem. Nevertheless, it seemed most of participants were not ready to take action to save ti. In addition, they also showed stereo-typically biased opinions about science, technology and their relationship with environmental issues. It appeared to come from media-oriented environmental education. Since pre-service teacher's conceptions could directly effect future education, it is necessary to establish a more systematic educational system for environmental education, for both pre-service teachers and students.

This study is a basic research to apply ESD linked to SDGs to pre-service teachers majoring in earth science education. The purpose of this study is to evaluate carbon literacy by analyzing the awareness, attitude and knowledge, subjective norms, and behavioral control of the carbon footprint internalized by pre-service teachers. Pre-service teachers recognize the carbon footprint as their responsibility, but are not willing to pay the cost and accept inconveniences of the actions to reduce carbon footprint. They also support actions to reduce carbon footprint, but do not demand the actions from others. While they have sufficient knowledge about carbon mitigation actions, their conception of causes and effects of global warming is unstable. Pre-service teachers will go out to school sites and teach millions of students about global warming. It is essential to educate these teachers on the economic cost and social responsibility of reducing their carbon footprints. It is also important to find ways to bridge the gap between their thought and action. It is hoped that this study on pre-service teachers' carbon literacy will lead to realizing ESD.

This study is to consider the fundamental perceptions of pre-service elementary school teachers to natural environments. The recognition items of questionnaire for those environments include ones of water, atmospheric, soil, biologic and oceanic environments constituting of the earth system. From the results of the study, they affirmatively recognized biologic environment, but they showed highly negative recognitions to others. In other side, it is considered that their recognitions to natural environments were probably transferred by the things which involve press media, curricula and real lives. On the basis of the study results, systematic teaching-learning for natural environments is essential because the encouragement of eco-friendly attitude, one of main goal for environmental education, is budded from basic understandings to natural environments. Affirmatively environmental worldviews for elementary school students are important for reasons why teacher's quality and practice will is fundamental, and then teacher could change the views of the students for environmental education. So, preparing balanced attitudes, right concepts and connection to applicable knowledges for natural environments, pre-service elementary school teachers in environmental education must be pointed to organized education between human and natural environment.
