This article provides robust empirical evidence for the association between science teachers' pedagogical content knowledge (PCK) and student achievement. Unlike previous studies, we employed two approaches (text-based vs. video-based tests) to assess if, and to what extent, teachers' PCK assessed by these two approaches are related to student…

It is widely assumed that teachers play a key role in providing high-quality learning opportunities to students and fostering students' learning. Yet it is still unclear how specific teacher knowledge facets as part of their professional competence contribute to classroom processes and learning outcomes. Focusing on mathematics education at the…

Schools experienced unprecedented disruptions to instruction during the COVID-19 pandemic, largely driven by the abrupt transition to online learning in the spring of 2020. Often, this shift created a "black box" around remote learning and instruction. However, data generated by educational technology platforms can provide a window into…

Pedagogical content knowledge (PCK) is one of the most important research topics in science teacher education. The purpose of this study was to investigate the PCK of science teachers with different teaching experiences and examine the effects of teachers' PCK on students' achievement and attitudes toward science. A mixed methods research design…

Scalable and accessible professional development programs have the potential to address the opportunity gap many teachers experience. Yet many asynchronous online programs lack interaction with and timely feedback to teachers. We addressed this problem by developing a virtual, interactive program that uses intelligent tutoring systems to provide…

Though wrought with challenges, the COVID-19 Pandemic, which led to the closure of schools worldwide and forced educators into a rapid transition from traditional to Emergency Remote Teaching (ERT), held some promise for furthering the integration of digital technology in schools. But now, years following the crisis, policymakers, administrators,…

This qualitative multiple case study explores the collaborations between three STEM middle school teachers and three STEM undergraduate mentors of color in an urban school district. Drawing on sociocultural theories and literature on culturally relevant education, we used a comparative thematic approach to explore how mentors contributed to…

This study aimed to explore Ethiopian middle school physics teachers' content knowledge (CK) and their implementation of Dialogic teaching (DT). A qualitative method, case study design, and purposive and convenient sampling employed in the study. Data collected using Classroom observation and Questionnaire from nine physics teachers. The…

Measuring teachers' skills and competencies is necessary to ensure teacher quality and contribute to education quality. Research has shown teachers competencies and skills influence students' performances. Previous studies explored teachers' knowledge through testing. Teachers' knowledge of the topic of area-perimeter and teaching strategies has…

Instructional quality is a research topic that has received increased attention over the past decades. However, despite evidence for its importance to student learning, few studies are designed to examine patterns of prevalent instruction. The present study aimed to enhance the understanding of instructional quality in Swedish lower secondary…

The purpose of this quantitative study was to investigate the perceptions of sixth, seventh, and eighth grade teachers in Tuscaloosa City Schools in relation to technology-enhanced practices and student engagement as a result of the "Digital Transformation Initiative". The Pre-service Teacher's Knowledge of Teaching and Technology TPACK…

This paper advances the conceptualization of STEM teacher professional knowledge reflecting the specialized knowledge needed to support English learner (EL) language development during science and mathematics instruction. What distinguishes this model is the integration of conceptual understanding, a key feature of subject matter knowledge, with…

Fractions are perceived as one of the most difficult areas in school mathematics to learn and teach. The most frequently mentioned factors contributing to the complexity are fractions having five interrelated constructs (part-whole, ratio, operator, quotient and measure) and teachers' pedagogical approaches to address these constructs. The present…

The purpose of this study is to examine how teachers' PCK is expressed in science teaching practice, both from a teacher's and a student's perspective. It is a qualitative study of three teachers' physics classroom lectures in grades 7 and 8. International research has highlighted the impact of teachers on students' achievement in general and in…

Diane Relf was concerned by what felt like an unbridgeable gulf between Year 7's vocabulary and comprehension, and her aspirations both for their inclusion in history and their later academic success. As a subject leader without the benefit of any history-specific training at the start of her career, she embarked on a journey of intensive reading…
