Making sense of algebraic expressions in context is multifaceted and extends beyond representing real-world situations using algebra. As part of Project MathTalk, the authors created videos that feature a pair of Grade 9 algebra 1 students coming to understand algebraic expressions in context. The students found three aspects of making sense of…

This paper explores what happens when animal slaughter is addressed in upper secondary school from a position of open solidarity with the animals themselves, i.e. "an animal standpoint." Drawing upon ethnographic fieldwork from a collaborative project with teachers, students, activists, and scholars, the paper explores what happens when…

This article reports on the design and implementation of a didactic sequence in the frame of a design-based research study. The research aim is to test the hypothesis that affordances of dynamic geometry may support students' awareness of logical relationships between geometrical properties of constructed figures. We elaborate on the task design…

This research investigated the potential of learning analytics (LA) as a tool for identifying and evaluating K-12 student behaviors associated with active learning when using video learning objects within an online learning environment (OLE). The study focused on the application of LA for evaluating K-12 student engagement in videobased…

This comparative study investigated the effect of supplementing problem-based learning (PBL) with video resources on students' academic achievement in physics, a unit of simple machines. It was carried out in the Ugandan Government and private lower secondary schools. The quasi-experimental design employed a cluster sampling design with 947…

On the basis of a substantial, robust, and well-replicated cognitive science research literature, interleaving has been recommended across a range of professional pedagogical works as an evidence-based strategy for mathematics teachers. This report first notes the conflation of interleaving and spacing effects underpinning those recommendations…

Video instruction has been widely studied and is generally considered as effective as live instruction for teaching scientific concepts and procedures. However, there is limited research on the effectiveness of prerecorded videos for teaching more challenging content. This study conducted a controlled experiment on over 300 high school students to…

This study was prompted by a desire to understand the relationship between reflective practice using classroom instructional video observations and teacher perception of effectiveness. This was a mixed methods study in which quantitative data were collected from a pre- and post-survey using a Likert scale and qualitative data from weekly pre- and…

Though text formats still dominate in educational contexts, the use of student-produced videos in the classroom is gaining popularity. Here the authors analyse how high school teachers in Catalonia, Spain, implemented video production tasks in their classrooms and the various challenges they faced during the process. The main data collection…

This article reports on analyses of the instructional practices of six middle- and high-school science teachers in the United States who participated in a research-practice partnership that aims to support reform science education goals at scale. All six teachers were well qualified, experienced, and locally successful--respected by students,…

Mathematics Preservice Teachers' (M-PSTs) conceptions of Mathematical Knowledge for Teaching (MKT) enhance their reflective skills because they utilize such conceptions to reflect on how to contextualize content knowledge during secondary mathematics teaching. While previous studies suggested M-PSTs develop MKT, including pedagogical content…

This study examined how preservice teachers (PSTs) develop adaptive competence in teaching peers in an introductory physical education pedagogy course underpinned by a pedagogical cycle designed to promote adaptive teaching competence. Two guiding research questions were: (a) what was the total number of adaptations that PSTs made in their peer…

Streaming is a divisive pedagogy in New Zealand due to the varied definitions of streaming, the ways streaming is perceived to influence the educational experience of young people, and the complexity of teaching students at a range of achievement levels. This article aims to gain an understanding of secondary school mathematics teachers'…

The utilization of instructional scaffolding is a crucial element in the process of imparting novel knowledge or skills to students. This approach involves the teacher providing and modifying support for students in order to optimize their classroom participation and academic outcomes. The present study offers an examination of a seventh-grade…

This study analysed how students' mobile phones and Snapchat are adapted to and participate in the classroom. Insights from the actor network theory were used to discuss the interconnections between students, mobile phones, Snapchat, desks, and plenary teaching. We applied video analysis to examine the minute details of unfolding sociomaterial…
