VisChem is a research and development project to study the effectiveness of molecular-level visualisation, produce animations of chemical structures and processes at this level, and develop effective learning designs, for a deep understanding of chemistry.
Roy Tasker is currently Professor of Chemistry at Purdue University with primary teaching responsibilities at first-year level, and research interests in the development and use of molecular-level visualisation and interactive multimedia for learning chemistry. Go to VisualizingChemistry.com to see his group’s activities.
Roy Tasker's interests are in how and what students learn in chemistry using interactive multimedia resources—in particular, by implementing learning designs that develop student mental models of the molecular world. In the VisChem project, Roy has led the team shown below to produce molecular-level animations, videos and supporting materials.
Roy Tasker collaborates with other science educators nationally and internationally to develop design principles for creating and presenting effective visualisations of the molecular world, and co-authors a first-year chemistry textbook Chemistry: Human Activity, Chemical Reactivity with an extensive variety of interactive multimedia learning activities. Roy received the Prime Minister’s Award for Australian University Teacher of the Year in 2011, and awarded an Australian National Senior Fellowship (see ScienceVis.com) in 2014 – 2016.
Roy Tasker is currently a consultant for universities on interactive, best-practice teaching with visualisation in face-to-face contexts.In workshops, he demonstrates the use of1) active learning strategies2) student response technologies for data mining to monitor learning gains and affective factors, and3) learning designs informed by an evidence-based cognitive learning model.
The VisChem animations were designed by Roy Tasker in collaboration with Bob Bucat (UWA), Ray Sleet (UTS), and Bill Chia (UWS) in the early 1990s. Rebecca Dalton (UWS) and Debbie Corrigan (Monash) implemented them in teaching contexts and studied their effectiveness.The original animations were produced by Stefan Markworth with assistance from David Hegarty’s team at CADRE, a multimedia production company.
