Blazing Trails in Africa

Wednesday, January 4th, 2012

Accra, Ghana

In reflecting on the year ending, my thoughts turn again to Africa, home of six of the world’s top 10 fastest growing economies. Africa’s mobile revolution is spawning exciting, new opportunities for entrepreneurs and engineers. For practitioners eager to experience the impact of their work, there’s no more dynamic and interesting place to be than Africa today.

With that in mind, I’d like to share three short but inspiring talks given in 2011 by three of Africa’s best and brightest pioneers.

He’s realizing his vision with Connexions, a collaborative software platform that enables anyone to create, share, modify and vet learning material accessible, at no charge, through Creative Commons licensing.

Currently, their content is accessed by over 850,000 users per month — a critical mass of global learners — making it one of the world’s most popular OER sites.

What’s next, I think, is the rise of global knowledge networks and learner-driven content made possible by the new generation of collaborative tools like wikis. Big things come from small steps…
