이 연구는 테크놀로지를 통합한 교사 교육 프로그램을 통하여 예비교사들이 TPCK 개발을 그리고 테크놀로지를 이용하여 학생들을 가르치는 동안 어떻게 그들이 실제교실에서 성공적이었는가를 묘사하였다. 다양한 자료들이 연구 문제를 해결하는데 정보를 제공하기 위해 사용되었다. 결국, 이 연구에서 교사교육 프로그램의 예비교사들이 TPCK를 이해하도록 돕는 것을 강조하는 것이 TPCK의 네 가지 요인에 의해 설명되어지는 예비교사들의 이해로 전이되었다. 하지만 신념, 교수, 테크놀로지 배경 다양성은 프로그램을 통하여 TPCK의 그들의 이해와 개발에 영향을 주었다.

With the rapid advancement of educational technology, recent studies have connected teachers' professional noticing with the use of digital resources in mathematical instructions. In this study, I examined elementary mathematics preservice teachers' attending and interpreting a mathematical software, ST Math, in the exploring and implementing phases. The findings indicate that preservice teachers paid attention to visual representations and manipulation prior to interactions with children and further took into consideration on task structures and situated context after interactions. They interpreted the events based on connected mathematical knowledge of prior interactions and further reflected on the progression of problem-solving strategies and sequence of tasks. In addition, four distinctive profiles of transitioning of evaluation on ST Math activities were identified with illustrations. Implications for noticing and teacher education were discussed.

이 연구는 논의 기반 일반화학 실험과정에서 나타나는 예비과학교사들의 모델링 능력 및 이의 변화과정을 알아보는 것을 목적으로 하였다. 이를 위해 일반화학을 수강하는 사범대학 1학년 학생 21명을 대상으로 6개 주제에 대한 논의 기반 일반화학 실험 수업을 진행하였으며, 예비과학교사의 모델링 능력을 알아보기 위해 논의 기반 일반화학 실험에서 작성하는 보고서의 모델링 단계를 분석하였다. 그 결과 모델의 요소에 대한 이해를 바탕으로 자신만의 모델링 전략을 가지고 있는 학생이 제시하는 모델의 수준이 높게 나타났으며, 논의 기반 일반화학 실험활동이 거듭되면서 모델링 능력이 향상되는 것으로 나타났다.

This study investigated the characteristics of preservice elementary teachers' science PCK through a mentoring program. Their perceptions of the mentoring program were also examined. The participants of this study were 33 preservice elementary teachers who prepared science lessons in small groups. A mentoring program was implemented in the processes of science lessons planning and evaluation to support their professional development. The characteristics of the preservice elementary teachers' science PCK exhibited through the mentoring program were as follows: They showed poor understanding of instructional models and logical connections of each instructional step. They also had problem in setting a clear learning goal for their science lessons. This was related with their poor understanding of the curriculum. They seldom considered students' misconceptions, and their perceptions of assessment were quite restricted. The analyses on their perceptions of the mentoring program revealed that the preservice teachers thought it was helpful for their professional development in several aspects. Mentoring could play an important role to examine and improve preservice elementary teachers' science PCK.

The purpose of this study was to investigate elementary student teachers' conceptions about the mechanism of the greenhouse effect, the greenhouse gases, the global warming, and their learning experiences of the greenhouse effect and the global warming. Participants were 82 student teachers in their second year of studies (science education: n=28, not science education: n=27) and in their fourth year of studies (science education: n=27). The open-ended questionnaire was used to examine the teachers' spontaneous ideas depicted by their drawings and/or writings. The results of this study are as follows: First, the student teachers' scientific response rate about key concepts related to the mechanism of the greenhouse effect was low (6.1%~28.0%); Second, although there are various greenhouse gases, it was only carbon dioxide that the student teacher's response rate was more than 80%; Third, only 17.1% of the student teachers clearly distinguished the greenhouse effect and the global warming; Fourth, there was a tendency that the student teacher group in the fourth year of studies and science education showed higher scientific response rate about the concepts than the other two groups.

This study examined what questions posed, and for arranging the matters, what decisions made, what practices put into by elementary preservice teachers during his or her enacting and reflecting mathematics teaching. Analysis of the study focused on the mathematics instructions practiced by four participants in practicum for senior students. Their own questions raised by each one in the instructional designs, performances, and reflections were picked out and categorized by five dimensions of mathematics instruction; the nature of classroom tasks, the role of the teacher, the social culture of the classroom, mathematical tools as learning supports, and equity and accessibility. Their instructional decision-makings and action-takings for answering to these questions were analised.

이 연구에서는 경북 지역의 사범대학에 개설된 화학교육론 강좌에 클리커로 알려진 교실 응답 시스템을 적용한 뒤 이에 대한 예비 화학교사들의 인식을 조사하였다. 강의 첫 시간에 클리커의 교육적 활용 방법과 사용법에 대해 소개한 뒤, 수업 중 평균 4-5개의 질문을 제시하였다. 이 질문에 대한 답을 예비교사들에게 클리커로 입력하게 한 뒤, 응답 분포를 확인하고 이에 대한 피드백을 제공하였다. 예비교사들에게 제시된 질문은 학습 내용을 회상하는 질문, 관련 내용에 대한 이해정도를 점검하는 질문, 어떤 사안에 대한 견해를 확인하는 질문, 이해가 어려운 내용에 대한 질문이 다양하게 포함되었다. 학기 말에 클리커 활용에 대한 예비교사들의 인식을 리커트 형식과 에세이 형식으로 조사한 결과, 예비 화학교사들은 클리커 활용의 인지적 효과, 정의적 효과, 그리고 매체 특성 측면 모두에서 긍정적으로 인식하였다. 8가지 클리커 질문 유형 중 예비교사들이 선호하는 유형은 개념 이해 질문과 학습 점검 질문이었다. 클리커를 활용한 구체적인 사례와 연구 결과에 대한 교육학적 함의도 포함되었다.

The purpose of this study is to investigate preservice secondary mathematics teachers' knowledge about graphical representation and provide implications for better mathematics teaching and learning in our schools. For this purpose, sixty-three preservice teachers were selected and given diverse graphical representation problems of y=1, y=x, x=0, $x^2+y^2=1$. All preservice teachers completed two types of questionnaires. First type is about constructing the graphs of the above each equation, and the second one is to make them find the appropriate graphs from given examples of the each equation. The results indicated that all the participant pre service teachers were unable to construct graphs in terms of various dimensions and various direction of coordinate axis. All of the participants represented the graph of each equation on only two-dimensional coordinate system. In addition, some preservice teachers believed that the axis of coordinates have to be x-axis on horizontal line and y-axis on vertical line. From this study, it is implicated that pre service teacher education program needs to provide the experience of representing the graphs of equation in terms of various dimensions and various direction of coordinate axis so as to develop their future students the flexibility and creativity in mathematical thinking especially in the area of space perception.

교육실습을 통해 교사자질에 어떤 변화가 있는 지 알아보고자 중 고등학교에서 교육실습에 참여한 교육실습생 98명(사범계열 40명, 일반 교직이수자 58명)을 대상으로 4주간에 걸쳐 교육 실습 전, 후에 따른 조사를 실시하였다. 연구결과, 교육실습 전 예비중등교사는 유능한 교사자질 5가지 영역에 대하여 교직관 영역에 대하여 가장 높은 점수를 보였으며, 사범계열 전공자들의 경우, 전반적으로 일반 교직 이수자들에 비해 유의적으로 높은 경향을 보였다(p<.001) 나타냈다. 교육실습 후 교사자질에 대한 5가지영역(교직전문능력, 교과지도능력, 학급관리능력, 교사인성, 교사태도)에서 모두 유의적으로 증가한 것으로 나타났다(p<.001). 사범계열 전공자의 경우, 교사자질에 대한 5가지 영역에서 모두 실습 후 유의적으로 증가한(p<.001) 반면, 일반 교직이수자는 교사로서의 태도 영역에서는 유의적인 차이를 보이지 않았다. 그러므로 예비 증등교원의 교사 자질 함양을 위하여서는 교육실습을 통한 교사교육 과정의 내실화가 요구되며 특히 일반 교직이수자들의 경우는 교사로서의 태도에 관한 영역의 강화가 필요함을 제시할 수 있다.

The purpose of this study was to examine teacher's perception, practices about the multicultural education. The subjects were 382 kindergarten teachers in G province. Kim A Young(1996)'s questionnaire which is modified and improved after preliminary research was used to measure teacher's perception and practices about the multicultural education. The data were analyzed by the descriptive statistics, t-test, one-way ANOVA, Scheffe test. The results of this study were as follows. First, Kindergarten teacher's perception about multicultural education were significantly different by teacher's teaching careers, teacher's kindergarten types, children's age, learning experience in preservice curriculum. Second, Kindergarten teacher's practices about multicultural education were significantly different by teacher's teaching careers and kindergarten types.
