This study investigated the perceptions of beginning teachers about teacher knowledge. Reflections and improvement of their class knowledge have been perceived as the most important factors by beginning teachers. In terms of utilization of actual classes, teacher knowledge, mathematical concepts and correlations such as connection linked to class contents and hierarchy have been used the most. Among the needed teachers knowledge, knowledge of student understanding and mathematics content knowledge was the most essential knowledge that could be mainly formed through classroom experience and teacher training program. On the other hand, knowledge about technology and assessment was not necessary or useful factor for beginning teachers. To facilitate formation of beginning teachers' knowledge, teacher introductory program, mentoring program, interactive relationship with teacher education institutes, curriculum improvement for teacher education institute and the development and dissemination of various teachers training program would be required.

The purpose of this study was to investigate beginning teachers' views of scientific inquiry envisioned in science education reform, which is the main goal of science education at schools. Teachers' views about scientific inquiry influence their students' learning in the classroom, so it is significant to investigate teachers' views about the scientific inquiry. 126 beginning science teachers participated in this study. The survey asking teachers' view of general scientific inquiry, nature of science (NOS) and the relationship of science, technology, and society (STS), was developed and implemented for 30 minutes. Alternative views of scientific inquiry including NOS and STS were emerged through data analysis with open coding system. The reliability and validity of data collection and data analysis were constructed through the discussion with experts in science education. The results of this study were as follows. Participants defined scientific inquiry as opportunities of 'Hands-On' and 'Minds-On' or its combination rather than 'Hearts-On'. However, teachers demonstrated the view of 'Hands-On' for the purpose of scientific inquiry and for teachers' roles in its implementation. The view of 'Hearts-On' about scientific inquiry was not identified. The naive view of NOS were identified more than informative one. More positive attitude about the relationship of STS was released. The implication was made in teacher education, especially structured induction program for beginning teachers.

The purpose of this study is to investigate beginner and experienced Korean science teachers' perceptions about the science teacher preparation courses from which they graduated, and to compare them. The study was conducted as a qualitative study using in-depth interviews. For the study, interview questions were developed by the authors based on the questionnaire of 'The IMPPACT project' that was being conducted in America. The interview tool includes questions about their experience of science subject matter content knowledge, science pedagogical content knowledge, and general pedagogical content knowledge in their preparation courses. For the interview, seven beginning science teachers, less than five years of teaching experience, and five experienced science teachers, more than five years of teaching experience, were sampled from secondary schools in Korea. The research results are as follows: First, most of the beginner and experienced science teachers perceived that the teaching methods in the classes of science subject matter were not good model for teaching science in their secondary school, because they were not diverse enough and entailed mostly knowledge transfer just through lecture without teacher-student interaction. Second, most of the beginner science teachers perceived that they were affected positively by the teaching strategies and evaluation methods in the classes for science pedagogical subject matter and they could apply those strategies and methods in their current science teaching. Lastly, most of the beginner and experienced science teachers perceived that general pedagogical subject matter is important and prerequisite for science teaching in their schools, but the courses that they experienced at their university were not appropriate for their current teaching.

The purpose of this research is to investigate the characteristics of beginning science teachers' subject matter knowledge (SMK) as revealed in their classroom teaching methods. In this research, we explored six beginning teachers' classroom teaching episodes on the 'work and energy' unit. Using open-ended interviews with the teachers and group discussions taking place on a regular basis to analyze and compare the classes of six beginning teachers, we extracted the features of beginning science teachers' SMK. Using grounded theory methods, the characteristics of beginning science teachers' SMK drawn from this research are: (1) beginning teachers' positivistic epistemology on science, (2) claiming the teacher's authority based on rich subject content knowledge, and (3) beginning teachers' science elitism. These epistemological characteristics are realized such PCK as (1) representational errors caused by the teacher's own science misconception, (2) doing harm to students with too much content knowledge, (3) sporadic content presentation lacking a focus, and (4) surplus class hours with lack of effective science teaching explanations. Suggestions for alternative perspectives on science SMK are presented by experienced teachers. In conclusion, science teachers' SMK is necessary, but not sufficient, for effective teaching. Science teachers' SMK does have an effect on science teaching, mediated by other types of teacher knowledge. The beginning teachers need a systematic support to transform their SMK into a viable PCK.

현재 과학교육의 목표는 과학적 소양의 함양이며 이를 구현하기 위해서는 교실에서의 과학탐구의 실현을 필수로 하고 있다. 과학자들이 경험하는 과학탐구는 "실질적 과학탐구(ASI)"라고 하여 필수적인 5가지 탐구요소(문제제기, 자료수집, 설명형성, 설명평가, 발표 및 정당화)를 포함하고 있다. 현재 사용하고 있는 지구과학내용의 교과서를 이 ASI 관점으로 분석하여 5가지 탐구요소의 분포도를 분석하고 이를 이용하여 지구과학탐구를 가르치는 초임교사를 대상으로 탐구에 대한 인식 및 교수실천을 같은 ASI관점으로 분석하였다. 탐구요소 2,3,4 에 해당하는 '증거수집', '설명형성' 그리고 '설명평가'는 빈번하게 나타났으나 탐구요소 1에 해당하는 '문제제기'나 5에 해당하는 '발표 및 정당화'의 기회는 나타나지 않았다. 특히 다른 과학(화학)과목 경우에 '증거수집'이 가장 빈번한 것에 비해 지구과학의 경우에는 '설명형성'이 주를 이루는 것은 지구과학탐구의 특징이라 할 수 있겠다. 또한 교과서 탐구기능은 SAPA로 분석한 결과 일반화, 의사소통, 예상, 그래프작성, 자료해석이 주를 이루었다. 과학적 소양을 함양을 위한 실질적인 과학탐구의 실현하기 위해서는 자유탐구와 같은 부차적인 기회를 통해서 경험하지 못한 ASI의 탐구요소의 기회를 학생들에게 부여해야 할 것이다. 또한 이 연구에 참여한 지구과학 초임교사의 과학탐구 인식 및 교수실천 또한 ASI로 분석한 결과 탐구요소 2번째에 치우친 경향을 보여주고 있었다. 실질적인 과학탐구의 실현을 위해서는 교과서에서 강조되는 탐구요소뿐만 아니라 다른 탐구요소를 경험할 수 있는 자유탐구를 개발하여 실용화해야 할 것이며, 관련 초임교사연수를 통해 초임교사들의 과학탐구에 대한 인식 및 교수실천의 반영 및 이들의 새로운 형성이 추진되어야 할 것이다.

This study is to explore the Pedagogical Content Knowledge of beginning earth science teachers about the porphyritic texture of igneous rocks, and to suggest the teaching device that can prevent a trial and error of students in earth science instruction. We developed an interview guideline concerned with basic perception on the porphyritic texture, formation condition and formation process of porphyritic rocks, teaching and learning on porphyritic rocks for it. And data was collected from 5 beginning earth science teachers (3 high schools, 2 middle schools) through a group discussion method. In result, despite the porphyritic texture can be found at hypabyssal rocks as well as volcano rocks and plutonic rocks, most beginning earth science teachers cognized that it could be found at hypabyssal rocks only by focusing the formation depth of hypabyssal rocks. Also, the formation of porphyritic texture should be considered the factors such as cooling rate, nucleation density, growth rate, growth time, etc. However they mainly reflected the formation temperature and growth rate as it's parameter. Participants have wrongly perceived that a phenocryst necessarily differs from a groundmass on chemical composition. And they are inclined to discriminate phenocryst from groundmass through their chemical differences, instead of grain size.

This study examined the meaning of creativity of children and teachers from two novice early childhood teachers' perspectives. Each novice early childhood teacher implemented a creative education program in her classroom for 16 weeks after getting a teacher training about children's creativity. At the end of each session of creative education program, each teacher had an evaluation time and wrote their reflective journals. Date sources were reflective journals, in-depth interviews, and several artifacts. The findings were as follows; 1) The meaning of children's creativity related to children's personal characteristics, such as thinking and acting differently as well as engaging fully in their current play. 2) The meaning of teachers' creativity related to teacher's personal characteristics, such as escaping from task-oriented tendencies as well as implementing with inventive flexibility.

The purpose of this research was to investigate the relationship between the change of beginning teachers' beliefs about a lesson and that of teaching practice and argument-based inquiry using science writing. Participants were three science teachers (A, B, and C) from different middle schools. Classroom observation and interview data were collected and transcribed for analysis. A Summary Writing test was also administered to examine whether there was an improvement in students' learning. The results indicated that the interaction between the teachers and their students developed, which is concluded as an improvement in the teaching practice. Teacher A and B also reported that teacher-student interaction had improved. Teacher A and C came to understand that argument-based inquiry using science writing classes constituted learner-centered instruction. The result from the Summary Writing Test showed the impact of the changes in teaching practice and in teachers' awareness of students' learning as well as produced meaningfully higher scores than compared groups on the rhetorical structure of all the specific areas in teacher A's school and on the scientific concept at B and C's schools.

The purpose of this study was to analyse beginning science teachers' PCK. For the purpose of this study, two beginning science teachers were chosen in public middle school. Qualitative data were collected through classroom observation recording, semi-structured interviews, and other document data. Data were analysed using the constant comparative method. The results indicated that the two beginning science teachers' PCK had little differences; both have insufficient knowledge of science curriculum and assessment, and their PCK had quite differences in the instructional strategies and the orientations toward teaching science. Though they were aware of students' various levels, their common teaching method focused on delivery of science text knowledge for poor understanding about student. In conclusion, the two beginning teachers' PCK were still similar with preservice teachers. To develop beginning teachers' PCK, it needs to change the paradigm of pre-service teachers education program and to expand in-service teachers training and supporting program.
