Undergraduate engineering students are commonly introduced to design in their first year and tackle a more authentic design challenge during senior year, with intervening courses focused on technical problem solving. Along this trajectory, students should acquire skills related to the development of engineering requirements, which are important to…

Over the past decade there has been a striking increase in the number of quantitative studies examining the effects of social mobility, with almost all based on the diagonal reference model (DRM). We make four main contributions to this rapidly expanding literature. First, we show that under plausible values of mobility effects, the DRM will, in…

The 21st century looks quite different in reality to the predictions made by science fiction writers. Instead of a world dominated by flying cars and androids, we have found ourselves living in the wake of a global pandemic, experiencing an increasing frequency of natural disasters, battling political turmoil and global refugee crises, all set…

Within education, we often encounter the urgent need to recruit teachers who possess subject-specific knowledges and who can pedagogically teach the students the right things. In this article, I turn to youth work and the statement "I have a plan to not have plan" to put forward another view of pedagogical work--one that views knowledge…

Knowledge tracing (KT) models predict how students will perform on future interactions, given a sequence of prior responses. Modern approaches to KT leverage "deep learning" techniques to produce more accurate predictions, potentially making personalized learning paths more efficacious for learners. Many papers on the topic of KT focus…

This article compares the Trump Organization's 2022 tax fraud conviction with a 50-year-old Canadian film "The Sloane Affair." The comparison yields timeless and timely insights into our tax system for business law students.

The recognition that researcher discretion coupled with unconscious biases and motivated reasoning sometimes leads to false findings ("p-hacking") led to the broad embrace of study preregistration and other open-science practices in experimental research. Paradoxically, the preregistration of quasi-experimental studies remains uncommon…

Community-based grassroots governance has been framed and endorsed as an exemplary model of social governance in China. This article explores how this governing philosophy is interpreted and appropriated within a migrant community in Yiwu, where language serves as a critical nexus between macro-level policy and micro language planning processes.…

Background/purpose: This study investigates the probabilistic thinking process in solving probability problems by prospective mathematics teachers with a field-independent cognitive style. The objective is to explore how individuals with this cognitive style approach problem-solving based on the three stages of Polya's framework: understanding the…

This case study used individual interviews to investigate graduate students' sensemaking in upper-level electrostatics in the context of problems that can be efficiently solved for the electric potential using Laplace's equation. Although there are many technical mathematical issues involved in solving Laplace's equation, the focus of this…

This research aimed to: (1) investigate the components and indicators of computational thinking learning experience management competency of early childhood teachers in educational institutions under the Office of the Basic Education Commission; and (2) examine the congruence of these components and indicators. The research was conducted in two…

In this paper, we have combined a pragmatic and a sociocultural perspective on how artifacts are used in technical problem-solving. With these perspectives we explore how three mechanical engineering students build a plastic spider together, using instructions they found on the internet. Ten hours of video recordings were selected for a detailed…

This article examines what constitutes a 'good' mathematical problem and proposes to conceptualize the notion of "collective mathematical problems" as phenomena that arise through and by way of the inter-actions enabled by the collective itself. The author examines how these collective mathematical problems can emerge in the classroom…

This qualitative empirical study uses interview data from 16 secondary school students in Austria, who experienced lessons in Critical Mathematics Education (CME), to understand how students perceive a CME approach. Despite the long theoretical tradition and the existence of practical reports from the teacher perspectives, there is a lack of…

The chromatographic separation of plant pigments is one of the most popular and visually appealing experiments encountered by young scientists when they are introduced to the principles of analytical chemistry. As such, it has found widespread application in schools, public engagement activities, and undergraduate laboratories. However, most of…
