This study used a cluster randomized controlled trial to investigate the effectiveness of two approaches to increasing middle school students' science learning when using an inquiry-based science curriculum. Eighty-nine schools, with 253 teachers and 20,591 students, were randomly assigned into one of three conditions: (a) a treatment condition in…

This paper presents Irish-medium immersion (IMI) teachers' perceptions of their development of content knowledge of language (CK-L) and pedagogical content knowledge of language (PCK-L) as a result of engaging in form-focused professional development (PD) which combined both content knowledge and pedagogical learning outcomes. An intervention,…

What do teachers know regarding word problem-solving in middle school? How confident are they in their knowledge? What do they believe is essential for them to know to teach word problem-solving? These three questions led to the current study in which 57 teachers who teach word problem-solving in middle school were examined regarding three factors…

Open discussion of text promotes students' reading achievement, yet classroom discussion is rare. The present study investigates whether teachers' knowledge for literacy teaching relates to their enactment of class discussion in the context of a high-quality literacy curriculum. Two sixth grade teachers (one who demonstrated high levels of…

We report on the differences in mathematics learning environments in classes taught by certified Elementary Math Specialists (EMSs) (n = 28) and their peers (n = 33) as determined by observations of instruction. We used path analysis to examine how variables such as mathematical knowledge for teaching, beliefs, and background characteristics were…

This study examined a cohort of middle school pre-service mathematics teachers' understanding of the rate of change as they engaged in a model development sequence. By adopting a design-based research perspective, a model development sequence on the concept of rate of change has been designed and implemented as part of a mathematical modeling…

This study explores the changing landscape of technology teacher education, in relation to the increasing integration of digital content, especially programming, in teacher education for grades 4-6 (pupils 10-12 years old) and how student teachers in Sweden perceive this content. Limited research exists on student teachers in technology,…

The present study is aimed to investigate in-service bilingual teachers' perceptions of training needs in the competences and knowledge required to implement bilingual curricula in Taiwan. To this end, this study used mixed methods consisting of questionnaires and individual interviews to collect data from the intended cohort, that is, in-service…

This mixed methods study explored the development of elementary and middle school preservice teachers' (PSTs) learning to assess student thinking through analysis of students' written work. Six sections of the first mathematics content course for teaching implemented two writing assignments focused on analysis of student work aligned to the…

Background: Renewable energy curriculum reflects research, standards, and policy documents that emphasize both environmental literacy and engineering, technology, and science concepts. Students' science achievement in this and other areas have been found to be predicted by their teachers' content knowledge. Therefore, this study examined whether,…

Purpose: This paper aims to explore developments over the past 25 years in the knowledge base on instruction-oriented middle leadership in schools. The authors document the trends in the literature since middle leadership began to attract scholarly interest in the late 1990s and explore the shifting structural and content patterns in the knowledge…

Online and blended learning (OBL) brings unique advantages to K-12 teachers and students. Thus, it is essential to prepare preservice teachers (PSTs) for designing effective K-12 OBL lessons in educator preparation programs (EPPs) so they can utilize OBL's distinctive characteristics to benefit their students immediately when they have their own…

This article describes specific components of each common content knowledge and specialized content knowledge within the pickleball context. In addition, it provides possible examples of each element aligning with the national grade-level outcomes associated with net games for 6--8th graders. This article allows teachers who are seeking meaningful…

Preparing teachers to teach science consistent with current reforms in science education is a daunting enterprise given a lack of high-quality science professional development (PD) adaptable across various contexts (Wilson 2013). This study examines the impact of a comprehensive professional development program on middle school teachers'…

This paper sought to explore the Knowledge of Algebra for Teaching and the algebra difficulties of In-field and Out-of-field Junior High School mathematics teachers using the expanded KAT framework. The study employed the descriptive survey design and involved the participation of 374 mathematics teachers using an achievement test instrument. The…
