To establish which factors predict student intentions to contribute towards an OpenCourseWare site, an online questionnaire was distributed among University of Queensland students via email. The 320 participants completed items that were based on the theory of planned behaviour and were designed to measure attitudes, subjective norms and perceived behavioural control. Measures of altruistic motivation were also included as a predictor for intentions to contribute. Overall, attitudes, subjective norms, perceived behavioural control and altruistic motivation explained 43.1% of the variance in students' intentions to contribute. Attitudes and altruistic motivation were the strongest predictors, accounting for 7.49% and 7.12%, respectively, with subjective norms accounting for 3.9%. Perceived behavioural control was not found to contribute to the explanatory model. The implications for universities creating new OpenCourseWare sites are discussed. Further research should investigate the effects of barriers on student intentions to develop and contribute and should examine the determinants of faculty support. (Contains 3 figures and 4 tables.)
