This study investigated the sustainability effects of the schema-based instruction (SBI) program and corresponding PD on the instructional practices of two cohorts of teachers (i.e., SBI experienced-teacher implementers and SBI novice-teacher implementers) and on students' ability to reason with proportions and overall mathematics performance. SBI…

This narrative qualitative study aimed to explore the perceptions of using Twitter as an effective professional learning tool for public school secondary-level teachers in Missouri. In addition, the researcher sought to find the perceptions of teachers who used Twitter for professional use, what they found to be valuable in developing a…

While there is widespread agreement that one-size-fits-all professional development (PD) initiatives have limited potential to foster teacher learning, much existing PD is still designed without attention to teachers' motivations and needs. This paper shows that the strengths and weaknesses of middle school mathematics teachers that engage in PD…

Background: Lack of content knowledge (CK) is problematic in teaching in classroom subject areas and in physical education. There is a dearth of data-based research on interventions aimed at helping teachers acquire CK and, in turn, on the effects of CK on student learning. Aim: To investigate the effect of professional development, in the form of…

Calls to advance students' ability to engage in mathematical reasoning practices including conjecturing, generalising and justifying (CGJ) place significant new demands on teachers. This case study examines how Mathematics Studio provided opportunities for a team of U.S. middle school teachers to learn about these practices and ways to promote…

While much is known about K-12 teachers' participation in professional development (PD) on inquiry-based science instruction, how professors facilitate such PD is not as well documented. This reflective, descriptive study documents the pedagogical practices of three professors during a two-week summer PD program on inquiry-based science…

This paper presents the findings of a study that examined the preparation and teaching practice of ten teachers of grades 7-12 from the Shandong province in China. This study revealed that a multi-dimensional training system has been developed to help the teachers gradually build up their knowledge base for teaching. The findings of this study…

The aim of this study is to study learning the positional ten base notation by the increase of students' test scores during the learning study process. Five teachers, one researcher and 53 students participated. Three research lessons in three different groups of students were conducted. The improvement in the third lesson (C) correlates with the…

Two related case studies of secondary mathematics teachers examine the roles and conditions helpful in initiating, directing, and/or supporting teachers' own professional development. Using multiple data sources from school-based and professional settings, we applied analytic induction to identify patterns of similarities and differences in…

Research has proven that teachers have a fundamental influence on student results. Moreover, effective teacher professional development is one of the key mechanisms for improving student achievement. By the most recent OECD (Organisation for Economic Cooperation and Development) definition, "Professional development is defined as activities…

Study aim: To determine if pupil physical activity and Body Mass Index classifications maintained or improved after a one-year professional development program involving both classroom and physical education teachers. Guskey's model of teacher change guided this study. Material and methods: Indigenous children from ten schools (N = 320) in grades…

This paper explores teacher beliefs that influence the ways Information and Communications Technologies (ICT) are used in learning contexts. Much has been written about the impact of teachers' beliefs and attitudes to ICT as "barriers" to ICT integration (Ertmer, Ottenbreit-Leftwich, & York, 2007; Higgins & Moseley, 2001;…

This article focused on a deeper analysis of pre-service teachers' observations of video lessons based on the authentic classrooms across three stages in eight sessions in order to reveal their changes in the abilities to understand pedagogical content knowledge and the effects of specific observation frameworks introduced in the observation…

English language learner (ELL) mathematics students at a California middle school did not meet Adequate Yearly Progress (AYP) toward state standards in 2010. The purpose of this project study was to examine 6th and 7th grade mathematics teachers' perceptions regarding differentiated instruction for ELL students' specific academic needs and to…

A challenge for educational employing authorities is the provision of high-quality, sustainable professional development opportunities that will lead to positive growth in teachers' pedagogical practices. The study reported here sought to devise and implement a model of teacher professional development that would result in such growth by…
