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…

Estimating and accounting for statistical uncertainty have become essential in today's information age, and crucial for cultivating a sound decision making citizenry. Engaging with statistical uncertainty early on can support the gradual development of uncertainty-related considerations that are often challenging to foster at any age. Statistical…

Peer ideas can be valuable contributions to scientific inquiry. Divergent peer ideas can enrich students' thinking and encourage curiosity. Meanwhile, similar peer ideas can promote convergent thinking that can reinforce understanding. However, students need guidance in critically evaluating peer ideas in relation to their own, and in recognizing…

This study examined whether learning with heuristic worked examples can improve students' competency in solving reality-based tasks in mathematics (mathematical modeling competency). We randomly assigned 134 students in Grade 5 and 180 students in Grade 7 to one of three conditions: control condition (students worked on reality-based tasks),…

Models and modeling are central to both scientific literacy and practices as demonstrated by the Next Generation Science Standards. Through a design-based research framework, we developed a model-based assessment (MBA) and associated rubric as tools for teachers to understand and support students in their conceptualization of the flow of energy…

We investigate an interactive teacher-generated drawing strategy in which the teacher constructs a drawing with the help of the students. The students contribute their ideas on how to visualize to-be-drawn concepts, embedded in an interactive process. The present study explored whether learning from a scientific text on plate tectonics could be…

Teacher learning is a huge challenge in instructional change, but relatively little work has carefully examined the mechanisms by which teachers learn, in contrast to the extensive work on programs that help teachers learn and the high-leverage instructional practices that are strong predictors of student learning. Specifically, relatively little…

The aim of the study was to investigate students' views of model evaluation through the lens of personal epistemology. We developed an integrated analytical framework by combining a developmental framework, including absolutist, multiplist, and evaluatist, with a multi-dimensional framework, including limits of knowing, certainty of knowing, and…

Proportional reasoning failures seem to constitute most errors in probabilistic reasoning, yet there is little empirical evidence about its role for attaining probabilistic knowledge and how to effectively intervene with students who have less proportional reasoning skills. We examined the contributions of students' proportional reasoning skill…

While previous classroom studies of status hierarchies tell us who has low status and how to increase those learners' participation in small group contexts via teacher-led interventions, we know little about how one becomes low status, or the role peers play in legitimating or delegitimating inequitable relations. This study used the sociocultural…

Conditions under which group work leads to learning have been studied in collaborative settings. Little is known, however, about whether and how the interplay between collaboration and cooperation impinges on group learning. In this paper, we study this interplay in the context of mathematical problem-solving. We focus on how training students to…

Collaborative learning involves the collaborative regulation of cognitive activities to establish common ground for the coordination of content. Drawing on research on cognitive scripts to embed collaboration in learning, this study examines the effect of the quality of the grounding and testing processes on the quality of the inquiry processes…

Comparing contrasting cases is a promising means to prepare learners for future learning from related direct instruction. The most prevalent type of preparation intervention used in this "case comparison approach" is providing contrasting cases together with comparison prompts. However, if the contrasting cases are complex learners might…

In the present study we investigate what problems adolescents in year-nine compulsory school face when trying to learn to play a song together, how they take on these, and how their teacher responds to these problems. The studied practice, where students are to form a band and learn to play a song together in music class, is an example of…

The mentor's background in educational roles has been presented as a moderator of School-Based Mentoring (SBM). However, the analysis of overlapping mentoring and teaching roles has been underemphasized in the literature. The aim of this study is to test whether the combination of mentoring and teaching roles influences the mentees' school…
