Who we are ?
The African Virtual University (AVU) is an innovative educational organization established to serve the countries of Africa. The objective of the AVU is to build capacity and support economic development by leveraging the power of modern telecommunications technology to provide world-class quality education and training programs to students and professionals in Africa. After a successful pilot phase, AVU has been transformed from being a project of the World Bank to an independent reputable Inter-governmental organization based in Nairobi, Kenya with over 57 Learning Centers in 27 African countries
Today : 68 learning Centers in 30 African Countries
What we doThe African Virtual University is working in collaboration with African Universities to identify the most essential program needed for Africa’s development. Upon identifying the programs the AVU partner with best universities in the world to developing content and delivery through our network to African students, professionals and civil servants
The technology model is responsive to the mixed mode delivery and pedagogical models utilizing a Learning Management System (based on WebCT) and satellite based content delivery network (VSAT) for video, online and Internet access.
The AVU Learning Resources :
A key aspect of the AVU ‘s mission is to increase access to quality higher education opportunities across Africa . The traditional residential University model currently adopted by most universities in Africa is unable to meet either current or projected demand . Therefore , there is a need to extend access outside the universities physical campus by developing high quality Open and Distance Learning capacity within AVU Partner Institutions, including those that make use of new technologies for e-learning where appropriate .
The Main Question is : How to expand the reach of the web , e-mail , and other learning resources in Africa ?
