Two novel proofs show that the sum of a specific pair of normal random variables is not normal are established in this note. This is one of the most often misunderstood facts by first-year students in probability theory and statistics. The first proof is concise using the moment generating function. The second proof checks whether the moments of…

This chapter discusses the history of source evaluation methods within the ever-changing field of information literacy, including a critical assessment of one popular approach, the CRAAP Test. The author then endorses an alternative approach, lateral reading, which encourages students to engage more deeply when evaluating digital resources in an…

In this article Antti Moilanen assesses criticisms of Wolfgang Klafki's model of exemplary teaching made by Meinert Meyer and Hilbert Meyer and by Chi-Hua Chu. "Exemplary teaching" is a style of discovery-based teaching in which students study concrete examples of general principles in such a way that they acquire transferable knowledge…

This paper scrutinizes the increasing trend of using international large-scale assessment (ILSA) data for causal inferences in educational research, arguing that such inferences are often tenuous. We explore the complexities of causality within ILSAs, highlighting the methodological constraints that challenge the validity of causal claims derived…

This editorial explores the intersection of equity and validity in language assessment, focusing on language-minoritized test-takers. Recognizing that tests often perpetuate inequitable power dynamics, our special issue, 'Equity Orientations for Validity Frameworks: Exploring the Intersections of Language and Assessment for Language-Minoritized…

I consider recent attempts to establish standards, principles, and goals for artificial intelligence (AI) through the lens of educational measurement. Distinctions are made between generative AI and AI-adjacent methods and applications of AI in formative versus summative assessment contexts. While expressing optimism about its possibilities, I…

Embodied cognition--the idea that mental states and processes should be understood in relation to one's bodily constitution and interactions with the world--remains a controversial topic within cognitive science. Recently, however, increasing interest in predictive processing theories among proponents and critics of embodiment alike has raised…

Adventure sports coaches must make sound judgements and effective decisions to ensure they can manage the significant risks present in an operating environment that is hyper-dynamic and has significant environmental complexity (Collins & Collins, 2013). High-level stakeholders in adventure sports require coaches demonstrate competency to…

In response to considerable critique of its rigour and relevance, the field of educational research has sought to prove its validity, both in terms of its scientific legitimacy and its relevance to policy and practice. One result of this has been a heightened concern with methodology, to the extent that a form of methodolatry has developed. In…

Since 1983, the Instructional Theory Framework (ITF) (and its subsequent improvements) has guided instructional designers and researchers in designing and developing useful learner experiences (LX). For the past 40 years, the ITF was laser-focused on the selection of instructional methods, downplaying delivery methods (media) and management…

Recent usage of virtual reality (VR) technology in surgical training has emerged because of its cost-effectiveness, time savings, and cognition-based feedback generation. However, the quantitative evaluation of its effectiveness in training is still not thoroughly studied. This article demonstrates the effectiveness of a VR-based surgical training…

Proof comprehension is an important skill for students to develop in their proof-based courses, yet students are rarely afforded opportunities to develop this skill. In this paper, we describe two implementations of an activity structure that was developed to give students the opportunity to engage with complex proofs and to develop their proof…

The introduction of generative artificial intelligence (GenAI) tools like ChatGPT has raised many challenging questions about the nature of teaching, learning, and assessment in every subject area, including science. Unlike other disciplines, natural science is unique because the ontological and epistemological understanding of nature is…

Museums operate and communicate ethically, professionally, and with the participation of their constituents, offering varied experiences for edutaintment and knowledge sharing. Today's museums ensure relevance in national and universal development by considering, first and foremost, educational functions. Museums work in harmony with people in…

Categorical growth models describe examinee growth in terms of performance-level category transitions, which implies that some percentage of examinees will be misclassified. This paper introduces a new procedure for estimating the classification accuracy of categorical growth models, based on Rudner's classification accuracy index for item…
