Research suggests that there is not enough integration of Information and Communication Technologies (ICTs) into subject teaching by graduate teachers across a variety of school settings. This points in part to the inadequacy of preservice teacher preparation. Hence, this research explores the question of how preservice teachers develop the necessary competence to teach, particularly science subjects, using ICTs, by examining the opportunities to learn (OTLs) that are provided at three different South African universities. Keywords: ICT, opportunities to learn, preservice teachers, science teaching, teacher education.
