This is a very good example on how technology can in no time leap and narrows the gap in education but I would want to air my concern on it.
On this and many forums there has been a concerted effort to want to access material held elsewhere at no cost to the person seeking the item(s). This is a false sense of justifiable "reditribution/gain" of material on the basis of costs. I know that some items (books/CDs/DVDs) may be unfavourably priced but that is an argument for another day. What I want to stress here is the false sense of gain that results in the kuchakachua mentality that does appear to be an accepted phenomenon in Tanzania at the moment. The gain is false because it is accepted that without having an attachment to something: full attainment of that things benefit will not be achieved, why? You do not have the attachment in this case, a monetary attachment where the cost you incur propels you to want to gain maximum benefit from it. You will strive to say if its a book, to go over and over its pages to gain the content. On the other hand if you didn't develop that attachment, it becomes yet another pdf, another CD-ROM brimming full of applications that you promise yourself that one day, yes one day you will get round to making use of it. That is the false attachment in my argument.
For your noble idea, this is my suggestion. There will be a cost involved in developing the said materials. You will find it increasingly hard to gain access to teachers to give you the material and if you succeed, there is the added cost to gather the material, quality check the content to ensure it falls within the syllabus in use and finally the cost of media and distribution. Unless there is a cost to the end user, believe me, if you supply CD-ROMS or DVD media, they will quickly get a new use for them, maybe decorations, maybe tea cosies and never attain what you have in mind.
As a people we don't have a good record in keeping/using to its fullest the things we get from donations, a recent article in the papers cited a water supply facility somewhere in DSM where a favourable drinks company built the facility and within a week, all the taps had mysteriously grown legs and disappeared. However, if this was implemented to have a management cost to the recipients, then they would have felt a need to keep/protect this vital resource that has been brought to their neighbourhood. Mzungu comes and shows us how to relieve ourselves, builds latrines and the like and in no time, we dismantle them through misuse and wait say for another Mzungu to come and save us again.
Enough of my rants but suggestion you propose is good, very good but the caution I put before you should help your suggestions and those who run with it some food for thought.
