The advanced visualisation and interactive capabilities make immersive virtual reality (IVR) attractive for educators to investigate its educational benefits. This research reviewed 64 studies published in 2016-2020 to understand how science educators designed, implemented, and evaluated IVR-based learning. The immersive design features (sensory,…

Tasker, Roy – Teaching Science, 2014
Why is chemistry so difficult? A seminal paper by Johnstone (1982) offered an explanation for why science in general, and chemistry in particular, is so difficult to learn. He proposed that an expert in chemistry thinks at three levels; the macro (referred to as the observational level in this article), the sub-micro (referred to as the molecular…

Williamson, Vickie M.; Lane, Sarah M.; Gilbreath, Travis; Tasker, Roy; Ashkenazi, Guy; Williamson, Kenneth C.; Macfarlane, Ronald D. – Journal of Chemical Education, 2012
A prior study showed that students best make predictions about the outcome of opening a valve between two flasks containing a fluid or vacuum when they view both a demonstration video and a particulate animation, but the study showed no influence from the order in which these visualizations were used. The purpose of this current research was to…

Velazquez-Marcano, Alexandra; Williamson, Vickie M.; Ashkenazi, Guy; Tasker, Roy; Williamson, Kenneth C. – Journal of Science Education and Technology, 2004
Different visualization techniques have been used for teaching chemistry concepts. Previous studies have shown that when molecular animations and video demonstrations are used, students seem to better correlate all three levels of representation: macroscopic, submicroscopic, and symbolic. This thinking process allows the students to improve their…
