Online social networks (OSNs), until recently, were tagged as child's play until they caused massive revolutions with upheaval of whole nations. This clearly announced the coming in of a new era with the empowerment of the masses through technology. Facebook, Twitter, YouTube and many others have changed the way interaction occurs. The world's largest universities have created their pages on the main OSNs, particularly those operating on the Open Distance Learning (ODL) mode. However, besides showcasing the activities of universities, these OSNs play an important role in the communication process. It is often assumed that student satisfaction can be measured in terms of student “likes” alone. However, this is misleading as comments reveal another “darker” picture of ODL. This study proceeds by a case study, based on a qualitative content analysis of the Facebook pages of some major ODL institutions. Findings reveal that there are some common problems faced by the student population which include simple queries about fees to complex advice on how to proceed during an interview. This mine of information could serve as a database to understand the student experience and serve as a basis for setting up viable solutions which will promote the image of ODL institutions in bridging frontiers with students.

A number of South African municipalities have embraced the use of advanced information technology to improve their services to citizens. However, this is not a common practice across the country; there are still municipalities within South Africa who have not automated their information systems for better service delivery to the public. This study develops a data model that can be applied by municipalities across South Africa as the basis for automating their information systems for service delivery. A combination of qualitative and quantitative methods is used. Preliminary data is collected using: (1) literature review, (2) observation at a selected local Municipality and (3) online related resources at two additional municipalities. The collected data is analysed and a generic conceptual municipality data model is drawn. Finally, the data model is further implemented in Oracle to create a test database for future Semantic Web processing.

The pilot study in the Iringa region, Tanzania, indicates how the modular interactive tiles can be used for playful physical rehabilitation for many diverse patient groups (handicapped children, stroke, cardiac, diabetic patients, etc.) in both urban and rural areas, and how it motivates the users through play to perform the physical rehabilitative actions. The system can be easily used by rehabilitation workers, and through the modularity it is robust to failure (e.g. power failure) in remote areas. The analyses of the use by many different user groups was condensed to a higher abstraction level to provide insight on the generalisation over the different user groups, and to provide pointers of opportunities and the means to meet these opportunities through subsequent development in the next cycles in the iterative research method. The pilot study indicates that the system can be a flexible and adaptive playful technology for rehabilitation in sub-Saharan Africa.

Approximately more than eight hundred (800) First Year Students at the University of Namibia in 2010 and 2011 were enrolled in Mathematics class against a few teaching staff. As such this resulted in a challenge to individual students' attention, which yielded low passing rate. To improve that, the students in their spare time tried to make use of computer services to revise and practice their Mathematics concepts. However, that was challenged by the fact that only a few students owned personal computers and the rest were deprived of such facilities. Nonetheless, in this era, the majority if not all students owned one or more mobile phones that had similar functions as that of computers. Hence, in order to improve the performance of all the students doing Mathematics, the m-Leaming System Enhancing Mathematical Concepts (m-LSEMC) was envisaged to accord opportunity to all learners in utilizing mobile phones during their spare time. The envisaged system was administered and yielded better passing rate.

ICT can contribute to the development and efficiency of education management and administration. Efforts to introduce ICT in teaching, learning and assessment aim to help meet a wide variety of goals in the education sector. This paper is based on a research project that was carried out in Strathmore University by @iLabAfrica, funded by the Kenya Education Network (KENET). The research was driven by challenges facing traditional assessment of large classes. It aimed at identifying e-assessment tools, evaluating if differences existed between performances of students examined with traditional assessment and those examined with e-assessment and investigating the feasibility of implementing e-assessment to complement eLeaming in the University. Findings revealed that a variety of tools existed and that e-assessment was better than traditional assessment in terms of students' performance, management of large classes, flexibility and cost effectiveness.

Mobile services and mobile content is available to diverse users in possession of the necessary mobile phones. However, some of the mobile services and mobile content is text intensive and this discounts low literate users in participation in the related mobile applications. Exploring typical challenges experienced by low literate users and adapting these mobile applications using visual interfaces can provide low literate users with usable access to mobile services and mobile content.

The development and roll-out of ICT and information systems in Africa has steadily increased in recent years as African nations attempt to bridge the gap between the digital divide. This increasing reliance on information systems has introduced many security risks, the existence of which has prompted the greater necessity to protect these systems. The use of knowledge-based, token-based and biometrics-based authentication security controls have contributed greatly in protecting information assets. However, it is also known that these systems have become increasingly susceptible to be being compromised. This reality has inspired research into additional authentication methods. Speaker recognition is one such method that offers many unique benefits, however it is not widely used. There are also no open and complete speaker recognition systems that could be found that may assist in the research process. This paper will provide an overview of speaker recognition along with the potential benefits and limitations, many of which are applicable in the African context. This paper also present an open identification and authentication enabled speaker recognition software prototype intended to serve as a platform for speaker recognition learning, experimentation and research.

This report describes the background, and related theories, results and reflections based on a research - innovation (R&I) model comprising multi-stakeholder co-creative workshops. The resulting new concepts, solutions and prototypes produced in a short limited time-scale are extraordinary compared to the outcome of standard research and innovation approaches. The developed prototypes and work-processes and the performed R&I model have in a positive way changed attitudes among many key stakeholders, leading to the start of new R&D programs pushing development of citizen centric services towards building a foundation for “positive living areas”.

Many young college and university lecturers working in remote rural areas or working in foreign countries away from home are deprived of the opportunity of pursuing post graduate university degrees because of a number of logistical problems such as distance from a university offering a PhD degree or restrictions in their temporary country of residence. These problems are compounded if there are connectivity problems such as low bandwidth Internet. This paper describes a programme designed by Sudan University of Science and Technology which issued a call for PhD supervisors from around the world. One supervisor from South Africa took up the challenge and implemented a “flipped classroom” model which worked well in constrained environments with low connectivity.
