The purpose of this study was to investigate changes in geological contents knowledge and self-confidence before and after the geological field trips. Fifty seven undergraduate students at a national university of education participated in this study. The questionnaires were developed by the researcher to serve the purpose. Findings were as follows. First, before and after the geological field trip, there was no significant difference in changes of geological content knowledge (p<.05). However, participants' self-confidence about the geological field trip changed significantly (p<.01). Second, there were no significant differences in changes of both variables in terms of gender (p<.05). And in this study, participants were grouped into two: science track that selected science areas and non-science track with social study selected in the college scholastic ability test. There were also no significant differences in changes of geological contents knowledge and self-confidence in terms of science or non-science track (p<.05). Third, in terms of the geological content knowledge, 24 pre-service teachers showed an increase, 12 students unchanged, and the 21 participants decreased. In contrast, per participants' self-confidence about the geological field trip, fifty three students indicated an increase with only one participant unchanged, and three preservice teachers decreased on the score. Finally, after the geological field trip, participants' comments indicated that they could feel the mystery of nature with the mind of a great experience. As a result, data showed that pre-service teachers became interested in geology, and motivated more in learning geological area than ever.

University teacher education programs have sought for ways of how to improve student teaching in order to supply mathematics teachers with practical theory to achieve the goals of the current educational reform in school mathematics. In this context, the purpose of this research is to investigate the effect of student teachers' teaching experience in the after-school mathematics programs and the ways of how to develop the after-school learning programs as an effective site for learning to teach based on the inquiry into student teachers' own teaching experience. For the purpose, data were collected through the interviews with the student teachers who had taught after-school mathematics class. In addition, data were collected through survey, class observation, and seminal meetings with the student teachers in order to supplement the findings from the interview analysis. Data analysis focused on the student teachers' experience with teaching in after-school mathematics classes, that is, what and how they had learned as teachers, what kinds of difficulties they encountered in their teaching and supports that they expect to improve their learning through teaching. The analysis shows that the teaching experience in the after-school programs had positively contributed to their development as future mathematics teachers. Specifically, the after-school programs provide the site for learning through teaching at the early stage of teacher education program. The after-school programs provided the students teachers for the opportunity to participate peripherally in educational practice of school. Through the participation, the student teachers developed positive attitudes toward teaching career and became to have more solid ideas about how to teach mathematics. Based on the analysis, this research provides following suggestions concerning how to improve student teaching. First, it is necessary to provide student teachers to participate into the practice of teaching at the early stage of teacher education programs. Second, it is important to give students teacher opportunity to participate in teaching at peripheral and legitimate positions. Finally, it is necessary to construct mentoring networks to support student teachers to move from a peripheral position toward a center of teaching practice.

이 연구에서는 기체 분자의 운동 방식에 관한 예비 화학 교사들의 오개념을 조사하기 위해 교재 분석 및 개념 검사를 실시하였다. 연구 결과, 일반화학 교재는 간단한 모형과 기본적인 개념 설명을 통해 기체 분자 운동을 다루고 접근 방식에서 차이를 보일 뿐 아니라 회전 운동에서 무게 중심에 대한 언급이 없는 교재가 상당 수 있었다. 이에 비해 물리화학 교재는 주로 분광학적인 측면에서 접근하였고 심화된 내용을 다양한 모형을 통해 제시하였으며 조사한 모든 교재에서 회전 운동의 무게 중심을 언급했다. 한편, 예비 교사들은 기체 분자의 운동 방식에 대한 이해 정도 및 자신감이 상당히 낮았으며, 많은 오개념을 지니고 있었다. 이는 예비 화학 교사들이 자신의 선개념에 근거한 직관 및 교재에서 제시한 시각 자료에 의존하는 경향이 크기 때문으로 생각된다.

Teacher quality is a topic of international concern, as it impacts student learning and teacher preparation. This study compared the undergraduate secondary science teacher preparation programs from two universities in Korea with those of Oregon, USA. We examined the programs' structural curricular coherence, conceptual curricular coherence, and curricular balance. Structural curricular coherence was determined by examining the overarching goals of the institutions' programs, the organization of the programs of study in terms of meeting those goals, and outside bodies of evidence. All universities were in structural coherence for various reasons. Conceptual curricular coherence was determined by examining students' perceptions of the connection between their preparation and their clinical practice. In case of Korea, most students from both universities were not satisfied with their practical preparation. In the US, the students from both institutions felt well prepared to transition to inservice teaching. To determine curricular balance, we examined the institutions' preparation programs looking at the credit hours taken in the four main areas of the teacher knowledge base: GPK (General Pedagogical Knowledge), SMK (Subject Matter Knowledge), PCK (Pedagogical Content Knowledge), and CK (Contextual Knowledge). The total credit hours taken in each category was very similar by country but the application and field component in the USA was far greater than those of Korea where the focus was heavily on SMK and PCK. The main reason for these may be the nations' licensing and employment processes.
