By 
Zimbabwean AI expert William Sachiti who is also CEO of UK-based start-up Academy of Robotics has published an open-source technology known as ‘Trees of Knowledge’ to improve access to education through smartphones in Africa. This free-to-develop technology enables a tree or rural landmark to broadcast a wifi connection providing access to a pre-loaded package of educational content. The wifi connection and content comes from a micro-computer moulded into the landmark to protect it from theft or damage. ‘Trees of Knowledge’ will convert trees and rural landmarks into educational wifi hubs in Africa
A community-driven,
secure and cost-free solution
Anyone within a roughly 100m radius can then access the
content on any mobile device free of charge. Users can also charge their phone
by plugging it into the accompanying solar-powered battery charging station.
The micro-computers will run on the power equivalent of a small rechargeable
battery and can run for years without maintenance. All the user needs is a
wifi-enabled device such as a phone, tablet, laptop or computer. There is no
need for the phone to be connected to a carrier or any network provider,
removing the issue of expensive data charges.
The technology uses a basic computer like the
Raspberry Pi computers which have been used in refugee camps in Lebanon by
UNICEF as part of its Raspberry Pi for Learning initiative (https://uni.cf/2OcP0zc).
A global crisis in education
Globally there are 258 million children out of school and UNESCO’s (https://bit.ly/2S17bci) new report Education Progress (https://bit.ly/2tew0Jn) highlights that the problem is particularly acute in
Sub-Saharan Africa where the population of primary-school aged children has
doubled since 1990 and 1 in 5 children of primary school age are out of school.
However, this is also a region witnessing rapid growth in smartphone adoption.
Already more than 23% of people in Sub-Saharan Africa have access to a
smartphone – a number which the GSMA estimates (https://bit.ly/2Oeyoaa) will rise to 39% in the next five years.
AI expert and serial entrepreneur, William
Sachiti, who was educated in Zimbabwe before moving to the UK where he started
his first technology company at 19 years old highlights the challenges:
“One of the challenges in
providing education through smartphones is that, while many people have access
to a basic smartphone of some description, in many areas 3G coverage is still
patchy. The data costs are high for most people and in rural areas keeping the
phones charged is a problem when there is limited or no electricity. Trees of
Knowledge aims to address all these challenges.”Sachiti adds:
“Every day millions of children
walk for hours to get to school in the hope – often a vain hope – that they
will find a teacher present at their school. In other cases, children are
unable to attend school because they need to take care of the family’s cattle
or support their families in other ways.
There is an urgent need to
improve access to education for these children. For many children their classes
are taught gathered under the shade of a large tree, so ‘Trees of Knowledge’
seemed a natural technical extension of this existing system.”
Recently, UNESCO Director-General, Audrey
Azoulay noted, “Rethinking tomorrow’s education must be done
collectively.”Sachiti believes that Africa’s burgeoning
tech ecosystem can play a vital role in this collective effort. His words:
“While
many programmes already exist to fix this problem, it is still not enough. With
the growth of the developer community in Africa, I believe we have the
opportunity to simply release the technology and let local communities build it
themselves. If this technology reaches one or two more children, then I feel it
would be a success.”
The pre-loaded educational content is likely to
be largely video-based and would be free to access by anyone at any time.
Whilst the system can work with existing educational content packages,
ultimately Sachiti hopes that content can also come from local educators.
