Jim Slotta is an associate level professor of education in the Ontario Institute for Studies in Education (OISE) at The University of Toronto. He holds the Canada Research Chair in education and technology and co-directs
the NSF-funded center called Technology-Enhanced Learning in Science(TELS). His research employs technology-enhanced learning environments to
investigate cognitive models of learning and instruction. He also promotes the development of open source materials for the learning sciences, and led the development of the Scalable Architecture for Interactive Learning
(SAIL). Slotta and his team are currently developing an open source technology framework for smart classroom research called SAIL Smart Space, which supports investigations of a new pedagogical model for knowledge communities and inquiry.

has focused on ways of optimizing students’ learning, especially in domains of sciences. Her early research investigated children’s competence as a function of knowledge and differences between novices and experts. More recently, she has focused on the origin of misconceptions, and explored approaches to teaching emergent, robustly misconceived processes. She has also published many articles on how students learn from generating self-explanations, from being tutored, from collaborating, and from observing and overhearing tutorial dialogues. Recently she introduced a framework that can differentiate students’ learning activities as active, constructive or interactive. Two of her papers have been ranked #1 and #7 most highly cited articles published by the journal Cognitive Science. Micki Chi is currently a Professor in the Mary Lou Fulton Institute and Graduate School of Education, Payne Hall/Box 0611, at Arizona State University, Tempe, AZ 85287-0611.
