Mike Stieff (Ph.D., Northwestern University) is Associate Professor of Learning Sciences and Chemistry at the University of Illinois-Chicago. His research focus on the development of new pedagogical and curriculum innovations to improve STEM learning. This work addresses three specific goals: (i) identification of the task-specific use of visuo-spatial strategies in scientific problem solving, (ii) characterization of the interaction of visuo-spatial ability and scientific expertise, and (iii) the development of visualization software for teaching high school and college chemistry. He is an expert in the design and evaluation of learning environments, particularly those in undergraduate STEM courses. His current projects explore new theoretical frameworks regarding the role of visualization and diagrammatic reasoning at multiple levels of science instruction and the design of simulations and animations for teaching science.
