  • 본 연구에서는 국내 정보 교사가 가지고 있는 교사 전문성의 특성에 대해 고찰하였다. 교사가 가져야 하는 전문성의 여러 종류 중 인지적 영역의 전문성은 학생 성취에 중요한 역할을 담당하기 때문에 가장 중요한 부분으로 볼 수 있다. 교사가 가지고 있는 인지적 영역의 전문성을 교과에 대한 지식, 일반적 교육학 지식, 교수 내용 지식으로 나누어 생각할 때 정보 교사는 세 가지의 전문성을 가지고 있다. 먼저 교과의 내용이 빠르게 변하기 때문의 지식의 개정이 빠르고, 교수내용지식의 많은 부분이 컴퓨팅 도구의 활용과 이에서 발생하는 오류에 대한 내용으로 구성된다는 점이다. 또한 이러한 이유 때문에 정보 교사의 교수내용지식 또한 꾸준히 변화하게 된다.

  • This study was to investigate novice teachers' Specialized Content Knowledge for Teaching in High School Calculus Lessons. The lessons of two novice teachers in Kyunggi Do were observed from July, 2011 to Feb. 2012. All observed lessons were audeotaped and transcribed into word files. Their calculus lessons were analyzed into three kinds of knowledge consisting of SCKT. Their SCKT just copied the contents of the textbook and other additional SCKT were not found for teaching. Even though students asked a question that they did not understand, the teacher just repeated the previous contents that already he used. But this study included possible contents of SCKT within the areas these teachers covered so that teachers in school may use for teaching of Calculus. The novice teacher do not have sufficient experience, the program of the college of education and the contents of the teacher certificate-examination should include multi-dimensional approaches in SCKT to pre-service teachers in order to raise better specialized teachers in mathematics.

  • This study investigated the components of science teacher professionalism, the meaning of PCK (Pedagogical Content Knowledge), examples of science PCK, and complementary measures that should be taken to improve teacher professionalism. Six science teachers recommended by their colleagues explained that the science teacher's professionalism (or professional knowledge) consists of science content knowledge, knowledge about teaching, knowledge about learners, and improvement efforts. Science teachers' definition of PCK, which is the professional knowledge that members of the wider society expect teachers to possess, is the teacher's materialized knowledge that aims at students' understanding and PCK is the accumulated know-how of teachers as they strive to make their teaching comprehensible by students. Science teachers also contended that teachers as professionals need to complement an accountability system, acknowledgement of continuous self-developmental efforts, collegiality, and securing validity in the teacher employment test. The teachers argued that the societal recognition of teaching professionalism is essential for a high quality teaching. Suggestions for how to improve science teaching professionalism are also discussed.

  • 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.

  • The purpose of this study is to look into practical knowledge of geography teacher that lead the teacher's conduct in performance assessment situation. In Classroom all activity of teachers is their unique creature and the behavior which express teacher's knowledge and competency as expert. Practical knowledge can be seen as a system of understanding that guides the teacher s decision, which involves the construction of contents to teach, methods of instruction, resources to use etc. Therefore if we fully read the teacher's instruction, we have to understand the practical knowledge of teacher. As an ordinary activity of teaming and teaching, performance assessment is conducted on active learning and teaching situation and has intention to advance learning. Thus All evaluating behavior conducted by teacher can be understood through the practical knowledge of teacher. For this purpose a series of performance assessment scenes conducted by teacher were selected observed and captured the imagery, principles and rules of practical knowledge through the qualitative research method. The result supposed that practical knowledge influence the whole process of geography teacher's performance assessment activity.

  • In this study, we analyzed the change of teacher knowledge through task design in the teacher-researcher community focused on knowledge of students in the area of derivatives application. The following subjects were studied. First, we have analyzed the focus of the discussion related to teacher knowledge of students within the teacher-researcher community. Second, we have analyzed the change of teacher knowledge of students according to the focus. The results of this study are as follows. First, community member' different knowledge of students led the discussion on the task solving paths. The main focus of the discussion was the possibility in inducing responses and motivation. Second, the process of reviewing and evaluating task solving paths and reaching consensus led the improvement of teacher knowledge. Teachers and researchers led changes of teacher knowledge by sharing the knowledge based on previous research and experience, respectively. This ultimately shows the necessity of co-learning between teachers and researchers in teacher education.

  • The purpose of study was to investigate practicing elementary teachers' pedagogical content knowledge and the significant predictors of their pedagogical content knowledge in science teaching. The PCK instrument was used to measure elementary teachers' pedagogical content knowledge. It consists of 6 factors to measure teachers' pedagogical content knowledge of 1)instructional methods, 2)representations, 3)contents, 4)evaluations, 5)students, and 6)curriculum. A questionnaire that consists of 7 questions regarding the teachers' degree, their number of years of teaching their choice of teaching science, their personal science teaching efficacy, their science teaching outcome expectation, their science instructional methods, and their attitudes toward teaching science, was also used to identify the information as to significant predictors of teachers' pedagogical content knowledge. A sample of 332 practicing elementary teachers participated in this study. To determine statistically significant predictors, Pearson's correlation coefficient and multiple regression methods were used to analyze the results. The results showed that the significant predictors of practicing elementary teachers' pedagogical content knowledge were their number of years of teaching, their science instructional methods, their personal science teaching efficacy and their attitudes toward teaching science. Further research of how teachers develop and construct their pedagogical content knowledge is recommended especially through the use of varied research methodologies that include qualitative methods.

  • Teacher knowledge needed for teaching is bound to be revealed in teaching the subject matter in relation to the given instructional context. Given this, recent studies on mathematics teacher knowledge tend to analyze actual Mathematical Knowledge in Teaching [MKiT]. This study focused on the dimension of transformation and its related codes in Knowledge Quartet, which has been recognized as a MKiT framework, and analyzed a Korean teacher's transformation knowledge revealed in her elementary mathematics teaching. The analysis showed that the codes related to the dimension of transformation were useful in analyzing teacher knowledge in the Korean context. However, a few codes need to be revised or added for more suitability. On the basis of these results, this paper closes with implications for analyzing teacher knowledge in mathematics teaching.

  • Since the importance of teacher knowledge in teaching mathematics has been emphasized, there have been many studies exploring the nature or characteristics of such knowledge. However, there has been lack of research on the tools of investigating teacher knowledge. Given this background, this study explored teachers' knowledge of fraction lessons using classroom video analysis. The analyses of this study showed that knowledge of teaching methods was activated better than that of student thinking or mathematical content. Knowledge of fraction operation was activated better than that of fraction concept. The degree by which teacher knowledge was activated depended on the characteristics of the video clips used in the study. This paper raised some issues about teachers' knowledge of fraction lessons and suggested classroom video analysis as an alternative tool to measure teacher knowledge in the Korean context.

  • There is no doubt about the importance of teacher knowledge for good teaching. Many researches attempted to conceptualize elements and features of teacher knowledge for teaching in a quantitative way. Unlike existing researches, this article suggests an interpretation of preservice teacher knowledge in the field of geometry using the Shulman - Fischbein framework in a qualitative way. Seven female preservice teachers voluntarily participated in this research and they performed a series of written tasks that asked their subject matter knowledge (SMK) and pedagogical content knowledge (PCK). Their responses were analyzed according to mathematical algorithmic -, formal -, and intuitive - SMK and PCK. The interpretation revealed that preservice teachers had overally strong SMK, their deeply rooted SMK did not change, their SMK affected their PCK, they had appropriate PCK with regard to knowledge of student, and they tended to less focus on mathematical intuitive - PCK when they considered instructional strategies. The understanding of preservice teachers' knowledge throughout the analysis using Shulman-Fischbein framework will be able to help design teacher preparation programs.
