Efforts by universities in sub-Sahara Africa to promote professional development of instructors in course design and delivery by e-learning technologies have often lacked meaningful impacts. This study investigated the impact of collaborative course design on instructors' professional learning about design and delivery of e-learning courses at the Open University of Tanzania (OUT). Six Teacher Design Teams (TDTs), each with 2 instructors, participated in the study, redesigning their print-based courses using an offline Moodle LMS supported by emails and mobile phones. A total of 36 interviews were conducted with 12 instructors, after each of the two workshops and after the course redesign process. Results showed that despite challenges, instructors were satisfied with collaborative course design and they reported that the strategy contributed to their professional learning. Instructors' backgrounds determined the kinds of support needed during course design and delivery.
IntroductionDistance education in sub-Saharan Africa is still characterised by the distribution of printed materials. However, the approach is associated with challenges which hamper student learning (Dzakiria, 2004), including (i) delays in the delivery of course outlines and study materials, and untimely access to learning resources, (ii) lack of regular and effective communication between instructors and students, (iii) lack of immediate feedback from instructors to students about their learning, and (iv) outdated learning resources and (v) feelings of isolation. A similar situation exists at the Open University of Tanzania (OUT) (Mnyanyi & Mbwette, 2009;Nihuka & Voogt, 2011a). E-learning technologies are considered to offer solutions for these problems. However, the application of e-learning technologies in developing countries is limited (e.g. Dzakiria, 2004;Mnyanyi & Mbwette, 2009), due to challenges instructors and students in most developing countries face. According to Resta and Laferriere (2008), only 4% of the African population has access to computers and the Internet. Narrow bandwidth is another challenge. Gakio (2006, p. 41) summarises the state of Internet connectivity in tertiary institutions in Africa as "too little, too expensive and poorly managed; as a result Internet technology becomes even less useful for research and education purposes". Other challenges are the lack of ready access to e-learning technologies by both instructors and students in most developing countries (e.g. Aguti & Fraser, 2006) and limited competencies in e-learning technologies amongst both instructors and students (e.g. Hoven, 2000).

233In an attempt to address challenges related to the limited competencies of instructors with regard to e-learning, OUT has organised professional development programs (mostly workshops and seminars) to prepare instructors for e-learning integration. However, these efforts generally did not lead to changes in instructors' practices. Instructors have continued delivering courses in the traditional way, u...
