In this paper, we demonstrate the fruitfulness of a theoretical framework called "Commognition," developed in the context of mathematics education research, for conceptualizing and analyzing a professional development (PD) process on measurement uncertainty for secondary physics teachers. Evaluating measurement uncertainty is an…

Background: Dealing with uncertainties is inherent in the engineering design process and often poses challenges for young learners. This necessitates providing learners with adequate support to navigate their uncertainties effectively. However, achieving this requires a deeper understanding of the factors influencing learners' uncertainty…

Cross-situational word learning, the ability to decipher word-referent links over multiple ambiguous learning events, has been documented across development and proposed to be key to vocabulary acquisition. However, this work has largely focused on learning from one-to-one structure, where each referent is consistently linked with a single label.…

Purpose: The purpose of this paper is to explore the phenomenon of organizational unlearning with a focus on challenging path dependence and its implications on the organizational change field. By generating a taxonomy of unlearning definitions and examining the dimensions, actors and processes involved, the authors aim to offer a holistic…

It is often asserted that to facilitate student engagement, encourage participation and create optimal learning environments, the classroom should be a safe space. In this paper, we explore the idea that 'safety' is at odds with the very nature of academic enquiry. Using data from a qualitative study with staff at a UK University, we illustrate…
