The present study examined the justifications used by children, adolescents, and adults to justify eating animals. Children (n = 100, M[superscript age] = 9.82, SD = 0.77, female n = 49) as compared to adolescents (n = 76, M[superscript age] = 14.0, SD = 1.62, female n = 36) and adults (n = 113, M[superscript age] = 44.1, SD = 14.4, female n = 54)…

Play, in particular sex-typical play, is important for affective, cognitive, and social development. There is limited research on sex-typical play in autistic children. The few prior studies on this topic relied heavily on reports or involvement of caregivers/parents, did not assess cognitive abilities, and examined a limited number of sex-typical…

Solving organic chemistry reactions requires reasoning with multiple concepts and data (i.e., multivariate reasoning). However, studies have reported that organic chemistry students typically demonstrate univariate reasoning. Case comparisons, where students compare two or more tasks, have been reported to support students' multivariate reasoning.…

This study aims at elaborating a well-established theoretical framework that distinguishes three modes of thinking in linear algebra: the analytic-arithmetic, the synthetic-geometric, and the analytic-structural mode. It describes and analyzes the bundle of signs produced by an engineering student during an interview, where she was asked to recall…

This paper aims to shed light on an overlooked but essential aspect of informal reasoning and its radical implication to mathematics education research: Decentralising mathematics. We start to problematise that previous studies on informal reasoning implicitly overfocus on what students infer. Based on Walton's distinction between reasoning and…

Critical thinking is embedded in national university graduate outcomes and included in international bodies' statements on higher education. At the same time, there are tensions surrounding critical thinking in higher education, such as its commodification, Eurocentrism, and relationship to rapidly digitalising cultures. Drawing from the…

This study investigated students' critical reasoning about commercials, as an aspect of advertising literacy. Critical reasoning was examined under two different experimental conditions. That is, students were tasked with watching four different commercials with 1) brand information provided or not, and 2) asked to engage in critical reasoning or…

Emotion is essential for learning, but brain evidence shows how not all emotional engagement is equivalent. New research by Mary Helen Immordino-Yang and the research team at the USC Center for Affective Neuroscience, Development, Learning, and Education finds that adolescents' dispositions toward emotionally engaged "transcendent…

This paper investigates how mathematics teachers describe their ethical decision making related to instructional practices, drawing on frameworks that incorporate both rational and non-rational approaches. We employed a multiple-case study method, selecting three teachers as cases through criterion sampling. Data were collected via four…

This study aimed to determine which type of information source--providing either mathematical or relative data--children aged 5-11 would prefer. Additionally, the study examined how children justified their choices and whether differences existed in their justifications. A total of 837 children participated in the study. The children watched…

Coding think-aloud transcripts is time-consuming and labor-intensive. In this study, we examined the feasibility of predicting students' reasoning activities based on their think-aloud transcripts by leveraging the affordances of text mining and machine learning techniques. We collected the think-aloud data of 34 medical students as they diagnosed…

Recent calls by legislators to exclude "divisive concepts" and histories from our curricula pose a challenge to the development of students' epistemic responsibility and agency in classrooms. In this paper, Martha Perez-Mugg examines the classroom as a space for the development of epistemic responsibility, ultimately suggesting that…

This concise, digestible book shows how the cultivation of reason became the defining aim of western education, and critiques how this aim has been eclipsed in recent decades by the neoliberal system of mass schooling imposed by the state. Chapters outline succinctly the history of western education and its origins in Ancient Greece, demonstrating…

Moral decisions often involve dilemmas: cases of conflict between competing obligations. In two studies (N = 204), we ask whether children appreciate that reasoning through dilemmas involves acknowledging that there is no single, simple solution. In Study 1, 5- to 8-year-old US children were randomly assigned to a Moral Dilemma condition, in which…

Siegel claimed that teachers are obliged to provide grounds whenever demanded, as a result of which they must be able to subject to scrutiny whatever they teach. In this paper, however, and taking as a reference Wittgenstein's "On Certainty," it is shown that such a demand cannot work for second language teachers because their main task…
