Abstract: Previous research has demonstrated that a refutational text challenging the commonly held conception that extrinsic reinforcement is a more effective strategy for motivating learning successfully facilitated conceptual change in preservice teachers. The purpose of this study was to extend this prior research by examining whether a motivational variable-teachers' intrinsic goal orientation-and a contextual variable-a controlling reward structure-moderate the effect of the text on preservice teachers' conceptual change. A sample of 188 undergraduate students enrolled in two upper- and one lower-division foundations of education courses read a refutational or non-refutational text about motivation, received a controlling or non-controlling extra credit reward structure, and completed a pre- and post-test instrument that measured their beliefs about motivating students. The conceptual change measured was separated into an intrinsic and extrinsic subscale to allow for a more specific analysis of the nature of conceptual change. ANCOVAs using intrinsic goal orientation, text type, and reward structure as independent variables, pre-test scores as a covariate, and post-test scores as the dependent variable revealed that (a) pretest beliefs were a significant covariate in the model, and (b) text type, goal orientation, and reward structure interact in significant ways to affect conceptual change. Particularly, post hoc analyses revealed that a controlling reward structure had a significant positive effect on conceptual change on the intrinsic and extrinsic subscale scores of students with low intrinsic goal orientations; however, for students with higher intrinsic goal orientations, a controlling reward structure appeared to undermine conceptual change. In the absence of a controlling reward structure, having a higher intrinsic goal orientation had a positive effect on conceptual change for both subscales. It was also found that regardless of goal orientation, providing participants with refutational text and a conditional reward structure most effectively facilitated conceptual change on the extrinsic subscale. Lastly, the observed conceptual change remained on the intrinsic scale scores and increased on the extrinsic scale scores after a 1-week delay.
