This study is aimed to determine whether there is any meaningful correlation between predictors and is intended to examine the relative influences that the pedagogical content knowledge of science teaching, scientific attitudes, science teaching intentions have on their science teaching efficacy. The results, showed that the childcare center teachers' pedagogical content knowledge of science teaching, scientific attitudes, science teaching intentions, and science teaching efficacy are all correlated with each other. The teachers' science teaching efficacy are predicted by their scientific attitudes, science teaching intentions, and pedagogical content knowledge of science teaching-learning methods. Specifically, for teachers of 0 to 2-year-olds, their science teaching efficacy is predicted by their science teaching intentions and scientific attitudes. For teachers of 3 to 5-year-olds, their science teaching is affected by their scientific attitudes and their pedagogical content knowledge.

The purpose of this study was to examine interactions among components of pedagogical content knowledge of middle school science teachers in a teacher learning community targeting science practice-based instruction. Data collection consisted of pre and post questionnaire and interview with each of five science teachers, audio-recording of teacher discussion in a teacher learning community, lesson plans, teacher written reflection, and video-recording of teaching practice. Qualitative data analysis revealed that there were two types of interactions, i.e., one-way interaction and two-ways interaction among components of pedagogical content knowledge of science teachers in a teacher learning community. There were also consecutive interactions as well as one-shot interaction. For two-ways interaction there were synchronous two-ways interaction in a teacher learning community meeting as well as consecutive two-ways interaction along with several meetings. This study provides implications that collaborative learning context in a teacher learning community should stimulate various types interactions among components of pedagogical content knowledge.

The purpose of this study is to analyze pre-service science teachers' pedagogical content knowledge. For this study, two senior education students were selected. The data of this study were collected through interviews, CoRe questionnaire, and classroom observation recordings during the period of student-teacher practice. Data were analyzed using the constant comparative method. The results indicated that the two pre-service science teachers had low level pedagogical content knowledge. Two pre-service science teachers' knowledges of science curriculum were different from each other. Orientations toward teaching science shifted to undesirable direction after the experience of a student-teacher's practice-teaching. Their subject matter knowledges were imperfect. They also had low levels of knowledge of students' understanding.

The purpose of this study is to obtain the basic data as a part of the knowledge-base to improve the expertise of the informatics teacher in the secondary school by investigating the perception level of the Pedagogical content knowledge (PCK) of the incumbent informatics teacher in the secondary school. For achieving this purpose, the subcategory of the Pedagogical content knowledge(PCK) was divided into 6 fields based on its theoretical background and the developed questions were modified to 31 questions by the experts'checking their contents validity, the survey was carried out targeting 34 incumbent informatics teachers in the secondary school and the result was analyzed. As a result of the measurement of the perception level of the Pedagogical content knowledge of the informatics teacher in the secondary school, the average score in the whole range of PCK was 3.87. Additionally, between two groups of under 10-year-experienced teachers and over 10-year-experienced teachers, the difference about the perception level of the Pedagogical content knowledge of the informatics teacher in the secondary school by work experience was came out as a 0.05 significance level in the educational process knowledge.

This research elaborated five components for pre-service mathematics teacher training: 1) Mathematical content knowledge, 2) Pedagogical content knowledge, 3) Pedagogical reasoning, 4) System of training, and 5) Mathematics teachers' beliefs. For the effect teaching, mathematics teacher program should be reformed. The key to improvement should be concerntrated on developing knowledge about effective teaching and translating it into algorithms those teachses can learn and incorporate in their planning prior to teaching. A theory of instruction should specify the most effective sequences in which to present the materials to be learned.

The article theoretically analyzed and specified definitions such as: "professional development of personality, competence, professional competence of a teacher". Structural components of professional competence are defined, namely: theoretical involves deep knowledge in the field of special pedagogy, special psychology; technological involves the use of acquired knowledge in practical activities and personal in which important personal characteristics of a special teacher are noted. Criteria and levels of development of professional competence of future special teachers are determined. The article analyzes the peculiarities of the professional activity of a teacher in the conditions of an inclusive educational space, in particular, the special training of a teacher as an integral component of this process. Emphasis is placed on the cooperation of teachers in an inclusive educational institution for the socialization of a child with special needs and her preparation for independent life.

The purpose of this study was to elucidate elementary school teachers' pedagogical content knowledge regarding the subject of "weight and pressure in water". 6 elementary teachers in charge of the 6th grade were selected for this study. The 7 hour lessons were observed over $15{\sim}20$ days, and a variety of data including scenarios, questionnaires for teachers, interviews of teachers were analyzed. As a result of this study, teachers who had long career histories thought that the purpose of teaching science was to teach the use of science principles, and teachers who had only taught for a relatively short time thought the purpose was satisfying students' curiosity. Most of the teachers felt that the science content knowledge related to buoyancy was insufficient. They had acquired most of the science content knowledge from teaming experiences in middle and high schools. The pre-service teacher education programs didn't help them to satisfactorily acquire the science content knowledge under analysis here. Most of the teachers taught the science lessons according to the order of sequence as shown in the science textbook. They didn't teach the contents that they thought were needed if they were not already included in the science textbook. Only one teacher who had taken science courses in high school managed the science classes freely according to his own thoughts and opinions. From the results of this research, it could be concluded that most elementary school teachers did not have enough pedagogical content knowledge to teach their students effectively.

Recent reform movement in mathematics education has focused not only on the curriculum development but also on teachers' learning or professional development. Whereas various theoretical paradigms call for different programs of professional development for teachers, one of the common emphases is on the pedagogical content knowledge [PCK] which encompasses contents and methods to teach. Against this background, this study developed comprehensive instructional materials for the purpose of fostering PCK in mathematics for elementary school teachers with 17 essential learning themes such as fraction, plane geometry, and area. Each loaming theme was first summarized on the basis of literature reviews and surveys in terms of knowledge in mathematics contents, knowledge in teaching methods, and knowledge in students' mathematical understanding and learning. Each theme was then analyzed in detail on how it was represented in the national curriculum and its concomitant textbooks along with workbooks. Finally, this report included a reconstruction of one unit in textbooks per each learning theme, followed by teaching notes and suggestions from classroom implementation. This was intended for teachers to apply what they might loam from this material to their actual mathematics instruction. Given the page limit, this paper dealt only with the learning theme of ratio.

It is the development of a mathematics teachers' teaching knowledge that manifests a mathematics teacher's professional knowledge growth. It is becoming a direct and effective approach of conversion of mathematical knowledge into the knowledge of mathematics teaching. Through the investigation, the study revealed that the knowledge conversion process of mathematics teachers in middle school is restricted by three aspects including eight factors. From this point, the authors have structured the path and model on influencing factors of middle school Mathematics Teaching Knowledge Conversion (MPCK), and discuss the mechanism of the transformation process.
