After the initial idea of having a computer adaptive game here is what we are planning to do:
Have a video lecture of 10 - 30 minutes on a basic topic like tables or basic algebra. This video lecture is shown to the learners.
After the lecture is shown, the learners can play "The game" through our SMS gaming system. Learners are sent messages containing questions that will quiz them on the topics of lecture. If the learner answers correctly then a more advanced question will be sent. If the learner fails to answer the question then a hint will be sent to the learner guiding her on how to attempt the question.
So with the method of teaching settled and the SMS gaming system almost ready we will be soon in position to conduct our first test.
