The purposes of this study were to evaluate the level of PCK which middle school science teachers have on the concept of density and to analyze the characteristics of science teachers' content representation on the concept of density by their PCK level. For that purpose, 20 science teachers were selected and asked to answer the questionnaire on the eight aspects of CoRe. Results of this study indicated that the science teachers' PCK levels were low in general and evaluated as below average. The differences among the characteristics of science teachers' content representation by their PCK level were high in seven aspects of CoRe but the one aspect of the understanding of learner's preconception. These differences were analyzed and the patterns shown by the science teachers in eight aspects of CoRe were drawn in this study. It was also found that the characteristics drawn in eight aspects of content representation shown by the teachers whose PCK level was medium were close to those whose PCK level was low rather than high in most aspects of CoRe.

This study is aimed at development of pedagogical content knowledge on fraction in the elementary school mathematics. Elementary students regard fraction as the difficult topic in school mathematics. Furthermore, fraction is the fundamentally important concept in studying mathematics. So it is important to develop the pedagogical content knowledge on fraction. The reason of attention to the pedagogical content knowledge is that improving the quality of teaching is the central focus of a high quality mathematics education. Shulman suggested that various knowledges are required for teacher to improve their classes. Of course, pedagogical content knowledge is the most valuable in teaching mathematics. Pedagogical content knowledge is related to the promotion of students' understanding about the learning. Pedagogical content knowledges are categorized by five factors in this study. These are understanding about curriculum, understanding about students and students' knowledge, understanding about teachers and teachers' knowledge, understanding about the methods, contents, and management of class, and understanding about methods of assessments. I develop the pedagogical content knowledge on fraction according to the these categories. I concentrate on the two types of pedagogical content knowledges in developing. That is, I present knowledges which teachers have to know for teaching fraction effectively and materials which teachers can use during the teaching fraction. Pedagogical content knowledges guarantee teachers as the professionalists. Teachers should not teach only content knowledges but teach various knowledges including the meta-knowledges which have relation to fraction.

The aim of this study was to measure preservice teachers' perceptions of Technological Pedagogical Content Knowledge (TPACK). The researcher analyzed responses on the TPACK scale of 307 students in A University located in Chungcheongbuk-do. During the statistical analysis, IBM SPSS 21 program was used to implement Independent Samples T-test, One-way Analysis of Variance, and Multiple Regression Analysis (Enter method). The results are as follows. First, for the mean difference by gender, the mean of female students was higher than that of male students in Pedagogical Knowledge, Pedagogical Content Knowledge, Technological Pedagogical Knowledge, and Technological Pedagogical Content Knowledge. Second, for the mean difference by grade level, the mean of the 1^st, 3^rd and 4^th graders was higher than that of the 2^nd graders in the Content Knowledge at a statistically significant level. Third, toward Technological Pedagogical Content Knowledge, Pedagogical Knowledge of .11 beta value, Pedagogical Content Knowledge of .11 beta value, and Technological Pedagogical Knowledge of .715 beta value were found to be statistically significant predictors. Finally, the researcher discussed development of the TPACK implementation manual and workbook and provision of various technology practice opportunities.

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 is for developing a programming education course to improve pre-service teachers' pedagogical content knowledge(PCK) of programming education. A 40-hour training course was designed with App Inventor, a block-based mobile programming environment, and with problem-based learning method and project-based learning method. After the curriculum was adopted to 12 undergraduate students, the effect of education was tested with a programming PCK questionnaire. As a result, after a 20-hour problem-based learning class, overall score and teaching method score were enhanced significantly. After another 20-hour project-based learning class, content knowledge, teaching method, and curriculum score were improved.

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.

수학 교사의 지식은 교과내용 지식, 일반 교육학 지식, 교육학 내용 지식, 교육과정 지식, 학습자에 대한 지식, 교육적 내용에 관한 지식, 수학 교육 목표, 목적, 가치에 대한 지식으로 분류될 수 있다. 지금까지 이러한 수학 교사에 대한 지식 종류에 대한 학문적 연구는 뚜렷하게 체계적으로 연구되어지지 못하고 주로 저학년 학생 및 학습자 위주로 산발적인 연구가 진행되어 왔다. 수학교사가 지녀야할 지식은 수학 학습자인 학생들을 어떻게 효과적으로 가르치느냐에 가장 직접적인 영향을 미치는 것이므로 이에 따른 구체적인 조사 연구가 필요할 뿐만 아니라 교사교육 프로그램에 반영되어 효과적으로 능력있는 교사를 양성할 수 있도록 하여야겠다.

The purpose of this paper was to investigate the pedagogical content knowledge of a middle school mathematics teacher manifested in his mathematics instruction by identifying the components of the pedagogical content knowledge of the teacher. For the purpose of the study, I conducted an interpretive case study by collecting qualitative data. The results showed that the pedagogical content knowledge of the teacher was characterized by: (a) knowledge of mathematics including connection among topics and various ways of solving problems; (b) knowledge of students' understanding involving students' misconceptions, common errors, difficulties, and confusions; and (c) knowledge of pedagogy consisting of his efforts to motivate his students by providing realistic applications of mathematical topics and his use of materials.
