Item Challenges and Instructors’ Intention to Adopt and Use Open Educational Resources in Higher Education in Tanzania(Higher Education, 2014) Mtebe, Joel S.; Raisamo, RoopeHigher education in Tanzania like in many other Sub-Saharan countries suffers from unavailability of quality teaching and learning resources due to lack of tradition, competence, and experience to develop such resources. Nevertheless, there are thousands of open educational resources (OER) freely available in the public domain that can potentially improve the quality of existing resources or help to develop new courses. The uptake and reuse of these resources in higher learning institutions (HLIs) in Tanzania has been very low. The study applied the unified theory of acceptance and use of technology (UTAUT) model to elicit instructors’ intention to adopt and use OER in teaching. The paper also investigated challenges that hinder instructors to adopt and use OER. A sample of 104 instructors selected randomly from five HLIs was collected and tested against the research model using regression analysis. The study found effort expectancy had significant positive effect on instructors’ intention to use OER while performance expectancy, facilitating conditions, and social influence did not have significant effect. Challenges that were found to hinder instructors to adopt and use OER are discussed. The findings of this study will help those who are involved in OER implementation to find strategies that will maximize OER adoption and usage in higher education in Tanzania.Item eLearning Cost Analysis of On-Premise versus Cloud-hosted Implementation in Sub-Saharan Countries(Management Information Systems and Higher Education, 2014-04) Mtebe, Joel S.; Raisamo, RoopeThe cost of acquiring, managing, and maintaining ICT infrastructure is one of the main factors that hinder educational institutions in Sub-Saharan countries to adopt and implement eLearning. Recently, cloud computing has emerged as a new computing paradigm for delivering cost effective computing services that can be used to harness eLearning. However, the adoption of cloud computing in higher education in Sub-Saharan countries is very low. Although there are many factors that may influence educational institutions to adopt cloud services, cost effectiveness is often a key factor. Far too little is known on how much the use of cloud computing can be cost effective in delivering eLearning services. This paper compares the cost of hosting eLearning services between on-premise and cloud-hosted approaches in higher education, taking Tanzania as a case study. The study found that institutions can significantly reduce the cost of eLearning implementation by adopting a cloud-hosted approach. The findings of this study serve as a base for educational institutions seeking cost effective alternatives to implement eLearning in developing countriesItem Investigating Perceived Barriers to the Use of Open Educational Resources in Higher Education in Tanzania(Curriculum and Social Inquiry, 2014) Mtebe, Joel S.; Raisamo, RoopeThe past few years have seen increasingly rapid development and use of open educational resources (OER) in higher education institutions (HEIs) in developing countries. These resources are believed to be able to widen access, reduce the costs, and improve the quality of education. However, there exist several challenges that hinder the adoption and use of these resources. The majority of challenges mentioned in the literature do not have empirically grounded evidence and they assume Sub-Saharan countries face similar challenges. Nonetheless, despite commonalities that exist amongst these countries, there also exists considerable diversity, and they face different challenges. Accordingly, this study investigated the perceived barriers to the use of OER in 11 HEIs in Tanzania. The empirical data was generated through semi-structured interviews with a random sample of 92 instructors as well as a review of important documents. Findings revealed that lack of access to computers and the Internet, low Internet bandwidth, absence of policies, and lack of skills to create and/or use OER are the main barriers to the use of OER in HEIs in Tanzania. Contrary to findings elsewhere in Africa, the study revealed that lack of trust in others’ resources, lack of interest in creating and/or using OER, and lack of time to find suitable materials were not considered to be barriers. These findings provide a new understanding of the barriers to the use of OER in HEIs and should therefore assist those who are involved in OER implementation to find mitigating strategies that will maximize their usage.Item Investigating students’ behavioural intention to adopt and use mobile learning in higher education in East Africa(Educational Assessment, Evaluation, and Research, 2014) Mtebe, Joel S.; Raisamo, RoopeRecent penetration of mobile technologies and its services in East Africa has provided a new platform for institutions to widen access to education through mobile learning. Mobile technologies provide learners with flexibility and ubiquity to learn anytime and anywhere via wireless Internet. However, far too little research has been conducted to investigate factors that contribute towards students' adoption and use of mobile learning in East Africa. We applied the Unified Theory of Acceptance and Use of Technology (UTAUT) model to investigate students’ behavioural intention to adopt and use mobile learning in higher education in East Africa. A sample of 823 students selected from five higher learning institutions was collected and tested against the research model using regression analysis. The results showed that, four factors: performance expectancy, effort expectancy, social influence, and facilitating conditions had significant positive effects on students’ mobile learning acceptance with performance expectancy being the strongest predictor. These findings will enable those who are involved in the implementation of mobile learning to develop mobile services that are relevant and acceptable to learners in higher education in East Africa.Item A Model for Assessing Learning Management System Success in Higher Education in Sub-Saharan Countries(Computational Engineering, 2014) Mtebe, Joel S.; Raisamo, RoopeIn recent years, there has been an increasing adoption of various Learning Management Systems (LMS) in higher education in Sub-Saharan countries. Despite the perceived benefits of these systems to leverage challenges facing education sector in the region, studies show that the majority of them tend to fail; partially or totally. This paper presents a model for evaluating LMS deployed in Higher Education Institutions in Sub-Saharan countries through adopting and extending the updated DeLone and McLean information system success model. The proposed model and the instrument have been validated through a survey of 200 students enrolled in various courses offered via Moodle LMS at University of Dar es Salaam, Tanzania. The findings of this study will help those who are involved in the implementation of LMS in higher education in Sub-Saharan countries to evaluate their existing systems and/or to prepare corrective measures and strategies to avoid future LMS failures
