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. These trailblazers all began their careers in technology, but now they’re developing “platforms” in the broader sense, enabling a new generation of Africans to reshape their future.

Each speaker offers their unique perspective, but a common theme from all of the talks is that Africa is rising rapidly. Through their courage and determination, Africa’s trailblazers can inspire us all to persevere, whether we work on the continent or not.


Learning through Collaboration

It’s always interesting to browse TED: Ideas Worth Spreading.  TED is like a virtual symposium of talented thinkers and doers.  The videos are bite-sized nuggets that can be sampled anytime you like—how cool is that? I’d like to get through most of them and catalogue my top picks for bold new insights.

Speaking of which, here’s a gem: It’s Rice University professor Richard Baraniuk (TED, 06) discussing his vision of creating a free online learning system based on collaboration among global instructors and learners.

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…
