The courses are brought to the schools as preinstalled apps on physical devices - the education of the teachers runs "offline". But how can you transfer the progress data of a teacher back into our online world to make it possible to react to potential problems? How can you use one handheld for teaching multiple teachers and still ensure that the quizz results stay confidential and are associated with the correct teacher? How can you find room for improvements of the courses? And how can you motivate teachers to stick with it and continue with the next module?
Although access to the Internet is not a given in rural Zambia, you can always find a GSM-capable mobile phone. Thus, the transfer of progress data is done via text messages.
Teachers send a code containing a user identifier, course identifier, and the result of the quizz to a phone number that is associated with our backend. Our software solution receives and processes the text message. A Web app makes it possible for the administrators to view and analyze this data and to encourage teachers again via the "offline"-channel of text messages to continue their education!
