This article considers the profound impact that Paul R. Pintrich had on the field of achievement motivation, specifically achievement goal theory. The article highlights Pintrich's groundbreaking research and theorizing, beginning with his early work integrating research on motivation and cognition and ending with his development of a multiple goals and multiple pathways to learning model. The article concludes with a discussion of 3 important directions for future research: (a) the testing and refinement of Pintrich's (2000a, 2000c) 2 * 2 model of achievement goals, (b) the advancement of methodology to better assess and analyze multiple goal pursuit, and (c) the continued expansion of research on achievement goals to include culture and context.
