Remedial Teaching System - Why Using Technology


Why using technology is making a difference?

The cost of technology hardware has gone down drastically. Today you get low specification but good quality tablets below USD $100. Such tablets can carry the whole curriculum for Primary and Secondary levels for formal education; including TVET. Through this technological advancement, a learner can carry thousands of books in a tiny device weighting less than 0.15 Kg. Using such tablets, we are promoting four important concepts:

  • Reducing the degradation of the environment by avoiding cutting trees due to the need of papers to produce textbooks
  • Usage of Open Educational Resources (OERs) widely and freely available and of high quality. Doing so, we reduce the purchasing or the production of expensive textbooks that most developing countries find difficult to afford.
  • Schools kids are exposed to the usage of technologies that is a requirement for this 21st Century.
  • Usage of renewable energy, such as solar energy to power the equipment hosting/accessing the content.

The remedial teaching system (RTS) is using the above four concepts to enhance the quality teaching and learning we are talking about. This system has been designed and being implemented by Africans to empower rural areas in Africa using existing technologies adapted to the African context in a sustainable way.

 The Remedial Teaching System (RTS) Interface 

This model has been designed for disadvantaged rural schools and with this in mind, we designed a system that is accommodating schools with no access to electricity and even no access to the Internet. Such system will permit learners in disadvantaged communities to get access to quality materials through a well engineered eLearning and mLearning systems.

As electricity in rural and urban areas in Africa is still a serious challenge, the whole system is powered by low cost solar energy and a hotspot is mounted within the school perimeter. Using such configuration, learners using low specification tablets will be able to access quality learning materials hosted on a low cost server.


The same system will facilitate access to quality Climate Change Education for Sustainable Development (CCESD) and DRR learning resources through integration approach while teaching any subject. One of the challenge of  CCESD integration in the curriculum is lack of resources for schools. Printing of such resources to serve all schools in every school in Africa is unrealistic due to cost involved and environmentally unfriendly.
