Dr. Ellen J. Yezierski (Ph.D. in Curriculum & Instruction/Chemistry Education, Arizona State University) is a Professor of Chemistry in the Department of Chemistry & Biochemistry and the Director of the Center for Teaching Excellence at Miami University. She is the co-developer of the NSF-funded Target Inquiry Professional Development Program and a former high school chemistry teacher. Her research group focuses on improving conceptual understanding of chemistry by examining the dynamics of teaching and teacher change. The goal of their work is to markedly reform instruction and improve chemistry learning across a variety of grade levels (high school and college). Current projects focus on instructional change and its outcomes using
the VisChem Approach (storyboarding chemical phenomena supported with dynamic molecular-level animations) and the evaluation of YouTube chemistry videos using Mayer's Multimedia Principles. In the VisChem project, Dr. Yezierski is now focusing on disseminating the VisChem Approach through the VisChem Community of Practice.

Dr. Roy Tasker has a Ph.D. in synthetic inorganic chemistry from Otago University, NZ, and is currently a Professor of Chemistry at Western Sydney University. He still supervises three graduate students from his time at Purdue University (2015 – 2018), co-authors the third edition of Chemistry: Human Activity and Chemical Reactivity, and is active in research on exploring the potential of immersive virtual reality learning environments for learning molecular-level chemistry.

His main focus is the development of learning designs for specific chemistry concepts, using the integrated suite of VisChem molecular-level animations and simulations, and informed by research in the cognitive challenges of multimedia learning (the VisChem Learning Approach).

In 2011 he received the Prime Minister’s Award for Australian University Teacher of the Year, and in 2014 – 2015 was seconded from university duties to conduct national workshops on the use of visualisation in tertiary science teaching in his Australian National Senior Teaching Fellowship (ScienceVis.com.au).
