In a first course in general relativity, the Schwarzschild spacetime is the most discussed analytic solution to Einstein's field equations. Unfortunately, there is rarely enough time to study the optical consequences of the bending of light for some advanced examples. In this paper, we present how the visual appearance of a thin disc around a…

The collaborative design of technology-enhanced learning is seen as a practical and effective professional development strategy, especially because teachers learn from each other as they share and apply knowledge. But how teacher design team participants draw on and develop their knowledge has not yet been investigated. This qualitative…

This article summarizes an investigation into how Flash-based cartoon video tutorials featuring molecular visualizations affect students' mental models of acetic acid and hydrochloric acid solutions and how the acids respond when tested for electrical conductance. Variation theory served as the theoretical framework for examining how students…

Computer-based simulations can help students visualize chemical representations and understand chemistry concepts, but simulations at different levels of representation may vary in effectiveness on student learning. This study investigated the influence of computer activities that simulate chemical reactions at different levels of representation…

Within the context of the telecom industry, this teaching case is an active learning analytics exercise to help students build hands-on expertise on how to utilize Big Data to solve a business problem. Particularly, the case utilizes an analytics method to help develop a customer retention strategy to mitigate against an increasing customer churn…

The current tendency to integrate Information and Communication Technology (ICT) into teaching challenges teachers to both develop and convey Technological Pedagogical Knowledge (TPK). This study examines the extent to which science teachers who have integrated ICT into their practice really demonstrate awareness of the aspects of meaningful…

This paper advocates the teaching of photo elicitation in higher education as a valuable data collection technique and draws on our experience of teaching this visual method across two consecutive postgraduate cohorts. Building on previous work (Watt & Wakefield, 2014) and based on a former concern regarding student duty of care, a…

Karina Wilkie discusses functional thinking in the primary classroom. She provides a useful learning progression with sample responses to a growing pattern task.

PowerPoint knowledge presentation as a digital genre has established itself as the main software by which the findings of theses are disseminated in the academic settings. Although the importance of PowerPoint presentations is typically realized in academic settings like lectures, conferences, and seminars, the study of the visual features of…

The topic of sorting algorithms is a pleasant subject of informatics education. Not only is it so because the notion of sorting is well known from our everyday life, but also because as an algorithm task, whether we expect naive or practical solutions, it is easy to define and demonstrate. In my paper I will present some of the possible methods…

Over the last two decades, a sense of awareness has arisen that universities are facing important challenges. This article focuses on the challenge that could be broadly termed as "the digitisation of academic work", yet without assuming that this digitisation would be an explanatory factor clarifying the precise nature of contemporary…

A quasi experimental study was done to determine significant positive effects among three different types of visual models and to identify whether any individual type or combination contributed towards a positive increase of spatial visualization ability for students in engineering technology courses. In particular, the study compared the use of…

The present study explored the problem-solving strategies of high- and low-spatial visualization ability learners on a novel spatial anatomy task to determine whether differences in strategies contribute to differences in task performance. The results of this study provide further insights into the processing commonalities and differences among…

Amongst important and under-researched questions are how introductory lessons can be designed for teaching initial proofs to junior high school students, and how such lessons enrich students' understanding of proofs. With a view to improving the learning situation in the classroom, in this paper we report on the various functions of introductory…

In this study we examined two prospective secondary mathematics teachers' constructions of box plots and their understanding of the distribution they were representing. The participants constructed box plots with paper-and-pencil, graphic calculator and TinkerPlots during clinical interviews. The study indicated that prospective mathematics…
