This study investigates teachers' perspectives on the use of a mathematical argumentation teaching strategy in elementary mathematics in which students disprove mathematical statements they already know to be false. Mathematical argumentation is a process through which students develop an argument about a mathematical concept and rationalize its…

Moral pride is a key component of virtue development. This study provides developmental insight into children's moral pride across cultures, and the potential for moral pride to underlie prosocial behavior. Participants included children and adolescents ages 6, 9, and 12 years from Canada (n = 186; 50% girls; ethnically diverse sample), Japan (n =…

How does a person make decisions across perceptual boundaries? Here, we test the account that confidence constitutes a common currency for perceptual decisions even in childhood by examining whether confidence can be compared across distinct perceptual dimensions. We conducted a strict test of domain-generality in confidence reasoning by asking 6-…

Problem and Objective: Transition to adulthood for young people with (IDD) is challenging for both youth and parents. Prospection, an important human adaptive tool and critical for independent living, involves constructing, encoding, and remembering the future. It may be jointly enacted between parents and young people as they discuss the future.…

With the rapid advancement of generative artificial intelligence (GAI), its application in educational settings has increasingly become a focal point, particularly in enhancing students' analytical capabilities. This study examines the effectiveness of the ChatGPT prompt framework in improving text analysis skills among students, specifically…

Our ability to shift from current to alternative (e.g., past and future) perspectives (i.e., "self-projection") plays a fundamental role in accurate decision-making. We investigated 3-, 4-, and 5-year-olds' ability to shift perspective to reason about their future and past preferences. In Experiment 1 (N = 96), children were presented…

Beta-adrenergic receptors ([beta]-ARs) prime hippocampal synapses to stabilize long-term potentiation (LTP). This "metaplasticity" can persist for 1-2 h after pharmacologic activation of [beta]-ARs. It requires activation of PKA (cAMP-dependent protein kinase) during [beta]-AR priming. A-kinase anchoring proteins (AKAPs) tether PKA to…

The development and evaluation of valid assessments of scientific reasoning are an integral part of research in science education. In the present study, we used the linear logistic test model (LLTM) to analyze how item features related to text complexity and the presence of visual representations influence the overall item difficulty of an…

This article examines the mathematics learning experiences in proportional reasoning I created for pre-service teachers in my teacher education course in Canada. The approach aimed to enable pre-service teachers to work on and with their prior mathematics understandings, make connections that were particular to what emerged during group work, and…

There has been a recent increase in research interest in the ways that visual representation is used to facilitate students' understanding in science classrooms. Yet while many studies have explored individual students' drawing, few studies have looked into drawing as a collective tool to engage students in thinking and talking together in science…

In two experiments (N = 64), we told 6- to 7-year-olds about improbable or impossible outcomes (Experiment 1) and about impossible outcomes concerning ordinary or magical agents (Experiment 2). In both experiments, children claimed that the outcomes were impossible and could not happen, but nonetheless generated realistic and natural explanations…

In this study, a research team made up of Métis artists and knowledge keepers, Anishinaabe and non-Indigenous educators, and a non-Indigenous university mathematics education researcher co-designed and delivered an Indigenous cultural mathematical inquiry in a Grade 5 classroom. We explored the connections between loom bead designs and…

Background: The current interest in models-based practice (MBP) as an innovation and framework has necessitated deeper understanding of both what MBP is and how teacher educators teach pre-service teachers about innovative approaches such as MBP. Despite several studies of individual teacher educators enacting MBP, there are few examples of how…

It is commonly assumed that belief-based reasoning is fast and automatic, whereas rule-based reasoning is slower and more effortful. Dual-Process theories of reasoning rely on this speed-asymmetry explanation to account for a number of reasoning phenomena, such as base-rate neglect and belief-bias. The goal of the current study was to test this…

Mathematical reasoning features in curriculum documents around the world, but is understood and enacted poorly by teachers in classrooms. We explore teachers' noticing of reasoning during observed lessons. Two teams of primary teachers in Canada and Australia worked to plan, deliver, and observe lessons intended to include reasoning. They observed…
