This article explores the legacy of Paul Pintrich in regard to theory and research in conceptual change. Specifically, this article reviews his vision for a view of conceptual change--a vision that integrated motivation and affect within a broader view of cognition in the classroom (Pintrich, 1999; Pintrich & Sinatra, 2003). This article describes 2 models inspired by his 1993 article, Beyond Cold Conceptual Change (Pintrich, Marx, & Boyle, 1993): Dole and Sinatra's (1998) Cognitive Reconstruction of Knowledge Model and the Cognitive-Affective Model of Conceptual Change (Gregoire, 2003), as well as our own personal view of intentional conceptual change (Sinatra & Pintrich, 2003). This article argues that the field may be changed inexorably by Pintrich's vision. Finally, this article describes Paul's ideas for future research in conceptual change.
