This research examines empirically the relationship between two measures of teacher quality: one based on professional standards and a second one using teacher value-added estimates. It also studies the extent to which teacher observable characteristics, such as teacher training variables, are associated to better performance on either of these…

This study examines how system-wide (i.e., region, district, and school) mechanisms such as leadership support, training requirements, structure, collaboration, and education affect the use of evidence-based practices (EBPs) in schools and how this affects the outcomes for students with autism spectrum disorder (ASD). Despite growing evidence for…

The purpose of this replication study was to examine the impact of the Teacher Study Group (TSG) professional development in vocabulary on first-grade teachers' knowledge of vocabulary instruction and observed teaching practice, and on students' vocabulary knowledge. Sixty-two schools from 16 districts in four states were randomly assigned to…

A continuing challenge for the education system is how to evaluate the wider outcomes of schools. Wider measures of success--such as citizenship or lifelong learning--influence each other and emerge over time from complex interactions between students, teachers and leaders, and the wider community. Unless methods are found to evaluate these…

Systematic studies on effectiveness of in-service teacher professional development (PD) are important for science education research and practice. Previous studies mostly focus on one certain aspect of the entire program, for example, effectiveness of PD on improvement of teachers' knowledge or students' learning outcomes. This study, however,…

The continuous professional development of teachers is crucial in our current knowledge-based society, yet empirical research on experienced teachers' learning outcomes is scarce. In this study, we examine perceived changes in classroom practices and in competence as outcomes. By making these outcomes measurable, we can relate them to several…

The present study examined the extent to which preschool classroom supports--relational support (RS) and instructional support (IS)--are associated with children's language development and whether these associations vary as a function of children's language ability. The language skills of 360 children within 95 classrooms were assessed using an…

Teachers can be seen as emotional workers often needing to be sensitive to the demands that their work makes on their emotions, and skilful in regulating their feelings, but few quantitative studies have examined this issue systematically. Using hierarchical regression analysis to examine this issue, this study investigates teachers' perceptions…

Teacher evaluation systems play an important role in teachers' professional development. This study examines which components of an evaluation system are related to the effects of the evaluation system on professional development from a teachers' perspective. Components such as leadership characteristics, the purpose of evaluation and features of…

Background/Context: Most reforms in elementary education rely on teacher learning and improved instruction to increase student learning. This study increases our understanding of which types of professional development effectively change teaching practice in ways that boost student achievement. Purpose/Objective/Research Question/Focus of Study:…

A multi-cohort cluster randomized trial was conducted to estimate effects of rich vocabulary classroom instruction on vocabulary and reading comprehension. A total of 1,232 fourth- and fifth-grade students from 61 classrooms in 24 schools completed the study. Students received instruction in 140 Tier Two vocabulary words featured in two…

School principals have a small to moderate influence on student achievement; however, this influence is largely indirect via the behaviors, beliefs, knowledge, practices, and competencies of their teachers. Despite a growing number of studies examining the indirect influence of school principals on student achievement, there is still much to know…

It is well reported in the literature that professional development activities have great potential to increase teachers' competencies in different areas, resulting in greater learning opportunities for students. In Turkey, however, teachers' participation in professional development activities is significantly lower compared to almost all…

This study used data from the Head Start Family and Child Experiences Survey (FACES) 2009 4-year-old cohort to examine associations among family characteristics, home and classroom environments, and the emergent literacy skills of Head Start children. Results from hierarchical linear models suggest that both family and classroom contexts play a…

This paper reports on secondary analysis of TIMSS 2003 data with the aim of explaining the difference in science achievement of Korean and South African learners. The question asked by this research, i.e. which factors at various educational levels influence science achievement in Korea and South Africa respectively, is addressed from the…
