In this study, we examined the relationships among years of teaching experience, professional rank, number of courses taken, and knowledge of algebra for teaching (KAT). 338 in-service and 376 pre-service secondary mathematics teachers in China completed a KAT questionnaire. Various statistical techniques were employed to examine these relationships. The pre-service participants teachers performed statistically significantly higher in advanced mathematics knowledge than their in-service counterparts. Among the inservice teachers, senior teachers had scored higher in school mathematics and teaching mathematics, compared with junior teachers. Yet participants' advanced mathematics knowledge decreased as their professional rank advanced or their teaching experience increased. The number of courses taken has significantly positive correlation with school mathematics knowledge and advanced mathematics knowledge. The implications of these findings for mathematics teacher education are discussed.

With the recent advancement of technology, there has been an increase in professional development activities, including teachers using blogs to share practical knowledge and reflect on teaching and learning. This study was conducted to identify the contents of practical knowledge shared through the K-12 teachers' blogs. To achieve the research objective, 70,571 blog posts were collected from 329 blogs of K-12 teachers in Korean and analyzed using text mining techniques. The results of the study are as follows. First, practical knowledge sharing activities using teacher blogs have increased. Teachers posted a lot of blogs during the semester. Second, primary school teachers share various curriculum activities, reflections on project classes, class management, opinions related to education, and personal. Third, secondary school teachers share summaries and reviews of curriculum, materials related to college entrance exams, various instructional materials, opinions related to education, and personal experiences on their blogs. This study suggested that blogs are widely used as a venue for sharing practical knowledge of teachers, and that blogs can be a useful way to develop professionalism.

컴퓨터교육의 영역을 교과내용학, 교과교육학, 그리고 컴퓨터활용교육으로 나눈다면, 컴퓨터교사의 지식은 교과내용에 대한 전문지식, 교과교육의 이해와 활용방법에 대한 지식을 주로 말한다. 그 중 교과교육학은 교수-학습을 위한 설계 및 운영과 평가를 말하는데, 본 논문에서는 교과교육학을 더 특성화된 지식으로 과목의 특성을 고려한 교과교육방법(PCK)을 살펴보자 한다. 교사교육에 대한 연구에 의하면 PCK에 대한 이해 정도와 교수능력은 학습자들의 학습효과와 밀접한 관계가 있다. 그러나 아직까지 우리나라의 컴퓨터교사의 지식과 PCK에 대한 연구는 아직 많지 않다. 수학교육과 음악교육이 효과적이기 위해서는 과목이 서로 다르게 접근되어야 하듯이 컴퓨터교육에서도 컴퓨터교과목의 특성과 방법적*상황적 지식을 포함하는 컴퓨터 교과교육방법적 지식(C-PCK)이 매우 중요하다고 본다. 본 논문에서는 컴퓨터교사의 전문지식의 하나로 C-PCK를 포함한 것을 제안하며, 앞으로 이어질 C-PCK에 대한 연구결과는 컴퓨터교육방법을 개선하고 컴퓨터교육의 정체성을 확보하는데 구심점이 되며, 예비교사양성과정에서 이론과 실제의 격차를 줄이는데 도움이 될 것으로 기대된다.

본 연구는 첨단과학 교사연수센터에서 실시한 교사연구경험(Research Experience for Teachers, RET) 프로그램에 참여한 세 명의 과학 교사들을 대상으로 한 사례 연구이다. 교사들은 RET 프로그램이 진행되는 6개월 동안 과학자의 연구실에서 실험 수행 경험을 하였으며, 이 경험을 토대로 학교에서 적용할 수 있는 교수 자료를 개발하였다. 교수법적 내용 지식(Pedagogical Content Knowledge, PCK)을 교사가 전문성을 갖추기 위해 가져야 할 지식으로 규정하고, RET 프로그램을 경험한 후에 나타난 교사들의 전문성의 변화와 그들의 전문성 발달에 영향을 미치는 요인을 탐색하였다. 3명의 참여 교사들은 RET 프로그램에 참여함으로써 과학 교수 지향, 과학 지식, 학생 지식, 교수 지식, 그리고 자원 지식과 같은 PCK 요소들의 통합된 발달을 보였다. RET 프로그램을 통해서 발달한 PCK 요소들은 학교에서의 교수 실행에 반영되었으며, 시간이 지날수록 교사들이 자신의 PCK 발달을 더욱 명확히 인식하는 것으로 나타났다. 이는 참여 교사들이 RET 프로그램을 통해서 진정한 맥락인 과학자의 연구실에서 ‘합법적인 주변 참여’를 통해서 학습했기 때문에 실제 과학의 과정을 알 수 있었으며, 교수 자료를 개발하는 동안에 새롭게 발달한 PCK요소들과 교사가 이미 가지고 있던 PCK의 통합으로 그들의 PCK가 학교 현장의 실행으로 이어지도록 발달하였기 때문이다. 한편 참여 교사들에 따라서 전문성 발달 요소와 양상에 차이가 있었는데, 이는 RET프로그램에 참여할 때 교사들이 가진 목적이나 그들이 가지고 이미 가지고 있던 PCK의 차이에 기인한 것으로 파악되었다. 본 연구는 연구 경험 제공을 통한과학 교사들의 전문성 발달 프로그램 개발에 의미 있는 시사점을 제공할 수 있을 것으로 보인다.

Purpose - This study was conducted to identify the impact of teachers' professional development on students' performance. It examines the nature of association between teachers' professional development and students' performance, and analyzes how students can be affected by different factors of teachers' professional development. Research design, data, and methodology - In order to obtain the required goals, Data were randomly collected from 100 students and 45 teachers from three different institutes that are affiliated with KPK Agriculture University, Peshawar. To test the association between teachers' professional development and students' performance, the Chi-square test was applied. Gamma measurement was computed to check the direction of association. Results - The results of the study supported the statement that there exists a positive relationship between teachers' professional development and students' performance. Conclusion - Based on the findings it is surmised that, in order to create a clear learning relationship between teachers and students, management must support the teachers through peer group discussions and training opportunities, and should choose-teachers who can make students pursue the learning of subject knowledge with practical implementation.

In this study, we examined the prompted reflections of four middle school mathematics teachers after their lessons. We used Cohen and Ball's instructional triangle (1999) to investigate teachers' reflections. With this framework, we addressed questions of what characteristics in reflections the participant teachers have and how the reflections differ over time. Findings indicated that the teachers showed differences in the instances of assessing and changes over time in the ways they gained more insights about students' understanding.

This qualitative study investigated two preservice teachers' conceptual ecologies in professional development during the science teacher preparation program. The notion of a conceptual ecology contains nature of knowledge, science and science teaching, learning, and content knowledge and comfort level. The data were collected during the participants' preservice year and their practicum experience. Both data collections and analyzing were from the various sources of interviews, teaching observations, journals, and information and profiles by the participants' supervisor. Two preservice teachers serve as cases representative of this study. Results show that problems preventing the preservice teachers from moving closer to conceptual change teaching were their understandings of the nature of science and the nature of knowledge. The preservice teachers' views about knowledge come from, and what knowledge is, are largely shaped by the nature of science and learning drive pedagogy and classroom practice. Knowledge of and comfort with the subject matter are also important.

Many studies on the professional development of science teachers demonstrated that induction teachers' conceptions of teaching science are important factors in developing their professionalism. The present study was conducted to describe in detail the progress of two science induction teachers, June and Mike, towards conceptual change teaching, and to investigate secondary induction science teachers' conceptions of teaching science by analysing their conceptual ecologies. The study was interpretive, using multiple data sources to achieve a triangulation of data. Both June and Mike held strongly positive learning in their views of knowledge and science. Holding positivist views of knowledge and of science is likely to be a major obstacle for anyone coming to understand constructivism and its implications in teaching for conceptual change. This argument resonates in several key ways with the teachers' cases, even though I recognize differences between scenario and teachers, and between teachers themselves.

Recently, increasing demand for teacher professional development and significant advances in information and communication technologies has led to a proliferation of online professional development. In spite of online professional development's popularity and advantages, research indicates that there is a concern of considerably high dropout rates of online learners. Therefore, to reduce the dropout rates of the learners, this paper is designed to help teachers identify professional development opportunities that are tailored to their needs as well as successfully complete these learning experiences. To achieve the purpose of the study, the paper explores the considerations for evaluating the characteristics of online learners and online professional development. Using these evaluations, this paper provides practical strategies for helping elementary and secondary education teachers successfully complete online professional development without dropping out an online course.

Investigating mathematics teachers in middle schools by questionnaire and interview, we find some problems of internal professional structure of mathematics teachers in middle schools. These are reflected in five aspects: professional theory, professional knowledge, professional ability, professional morality, reflection and innovative consciousness.
