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 study describes a novel measure of children's Theory of Mind (ToM) development--called the Comprehensive Assessment of ToM (CAT)--that addresses limitations in existing ToM measures. This behavioral measure includes three-six items each about diverse desires, diverse beliefs, knowledge access, knowledge expertise, false belief, and visual…

Purpose: Abstract thought builds the basis for problem-solving and knowledge consolidation across the disciplines of science, technology, engineering, and mathematics (STEM). Scientists across these fields acknowledge its significance and have approached the topic from their distinct perspectives, and yet, in STEM, there is a lack of a unified…

When students learn with--and from--other students, it is called peer-assisted learning (PAL). How undergraduate medical students use their peers for their clinical-reasoning learning process remains unclear, although literature suggests that it is a promising learning strategy at this stage. This research therefore explores the question: 'How is…

The goal of the present study is to illuminate students' proportional reasoning using the theory of units coordination as an explanatory tool. We chose two seventh-grade students, Hyun and Junwoo, who demonstrated distinct levels of units coordination and analyzed their units-coordinating activities under proportion problem situations with respect…

Teaching to support students' sense-making is challenging. It requires continuous, context-dependent decision-making about which student ideas to pursue, when, how, and why. This paper presents a single case study of an experienced teacher, Nadine, as an illustrative case in order to provide a rich description of this teacher's decisional…

Definitions are an integral aspect of mathematics. In particular, they form the backbone of deductive reasoning and facilitate precision in mathematical communication. However, when multiple non-equivalent definitions for the same term exist, their ability to serve these purposes can be called into question. While ambiguity can be productive, the…

In this paper Michael Vazquez and Dustin Webster consider the practice of deliberating about ethical case studies as a means to contribute to the professional development of educators. An ongoing debate is whether or not the study of ethical theory should be included in this practice. Vazquez and Webster argue that a popular strategy, known as the…

The present work refers to a study of 10-12-year-old students' ideas on the self- or hetero-luminosity of the Moon. To check the validity of students' reasoning on this question, we also examined their ideas on the lunar phases and how we see hetero-luminous objects. Students supported their ideas on the self- or hetero-luminosity of the Moon by…

Abstraction is essential to learning mathematics because the mathematical concepts obtained through abstraction will be more meaningful than directly receiving these concepts. This study aims to describe the pre-service teachers' abstraction in constructing relationships among quadrilaterals. This research method was explorative qualitative…

Although actual experiences of upward social mobility are historically low, many adolescents and adults express a "belief" in social mobility (e.g., that social status can change). Although a belief in upward mobility (e.g., that status can improve) can be helpful for economically disadvantaged adolescents and adults, a belief in upward…

Inequalities in access to important resources and opportunities between social groups persist throughout societies worldwide. Social psychological research has shown that adults often use meritocratic beliefs to justify the existence of such inequalities. Yet, the developmental origins of meritocratic beliefs have yet to be fully explored. This…

The ideas of measurement and measurement comparisons (e.g., fractions, ratios, quotients) are introduced to students in elementary school. However, studies report that students of all ages have difficulty comparing two quantities in terms of their relative size. Students often understand fractions such as 3/7 as part-whole relationships or…

In order to learn more about student understanding of the structure of proofs, we generated a novel genre of tasks called "Proof Without Claim" (PWC). Our work can be viewed as an extension of Selden and Selden's (1995) construct of "proof framework"; while Selden and Selden discuss how the structure of a proof can be discerned…
