A mixed methods randomized control trial (RCT) was employed to investigate the social validity ratings (i.e., acceptability, appropriateness, and feasibility) of middle-school students using an innovative program of virtual social scenarios called VOISS (Virtual reality (VR) Opportunities to Integrate Social Skills) compared to an evidence-based,…

Teacher enthusiasm is known to affect students' learning in traditional classroom environments, but it is unclear how displayed teacher enthusiasm can optimize learning of chemistry procedural knowledge in multimedia learning environments. In this context, the present study used eye-tracking technology and quantitative analysis to examine how…

Video magazines can make students' learning experience more effective by adding a different dimension to the learning process. This learning experience can create changes in students' attitudes and behaviors. This study aimed to investigate the impact of video magazines in the experimental group. It printed magazines in the control group on middle…

In this study, we investigated the impact of prompting on young students' source consideration when watching videos with conflicting information. 262 French 7th graders were shown a series of videos in which two speakers (varying in credibility) took opposite stances on the topic of organic farming. The students were either given no prompts…

Empirical studies demonstrate that students have some difficulties with the mathematical modeling process. Studies contain various applications for developing students' modeling competencies. This study investigated video-based modeling tasks' impact on modeling competencies with a descriptive design. In this context, it aims to compare…

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 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…

While video feedback is a commonly used intervention in both professional and educational sports settings, empirical evidence on the effectiveness of training with augmented video feedback in physical education at the K12 level is quite scarce. For this reason, this study aims to investigate the effect of the training with augmented video feedback…

This mixed-methods study explored the impact of cinematic virtual reality (CVR) on seventh-grade students (n = 66) in a school library. The research was comprised of two phases, integrating data from questionnaires and student/teacher interviews. The study focused on "The Displaced," a documentary about child refugees, presented in two…

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…

The purpose of this study was to assess the impact of young students' prior attitude on source consideration when watching videos on controversial topics. Two hundred seventy-one seventh graders watched a series of videos in which two interviewees (one expert in the field, one layperson) expressed divergent positions on a socioscientific issue…

This study developed a teacher education program for teacher education students (TESs), incorporating collaborative inquiry and panoramic cameras to guide them in observing young students' learning performances during teaching, with the goals of enhancing instructional design capability for diagnosing student learning problems and investigating…

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…

Cognitive demand is a crucial dimension of instructional quality. Its heterogenous operationalizations call for refined investigations, with respect to discursive richness (generic conceptualizations) and conceptual richness (subject-related conceptualizations). Considering not only teachers' intended cognitive activation (operationalized, e.g.,…

Many researchers have studied who and what teachers notice from video and some have focused on the analytic stance of teachers, meaning how noticing occurs. We complement existing work with a focus on analytic stance in a particular mathematics domain, proportional reasoning. We engaged 30 practicing teachers in an online course that included…
