In my school we have an MIS that seems to have evolved from an Access Database created in the 90s, that manages all student data, but has no API. We also have a VLE that was designed to look pretty, but offers almost no functionality and has a UI that is tortuous to use and actually lengthens the time it takes to mark work and record results.
Every teacher I work with has a different way of operating. Some write assignments on the board and take in hard copies. Other's use the official VLE. Some use email or shared network drives, and others Edmodo or whatever platform is flavour of the month.
Work is marked and fed back to students, and then inevitable placed in an Excel spreadsheet, exported as a CSV or transcribed into a paper mark book, only then to be then double entered into our MIS at a later date.
The system is a mess, and every new Edtech tool I see just adds to the confusion - another URL to remember, another username, password, interface. I wonder how many Edtech startups have founders that were actual teachers, or bring teachers on board at an early stage. Judging by the tools on offer, I would guess that it's not many.
There are a couple of exceptions. EdX, I think, is an amazing platform, but even though it is OpenSource, it is well beyond the capabilities of most schools to set up an in-house platform. Codecademy seem to genuinely want to engage with teachers (in the UK at least) but where are the Codecademy startups for Geography or French or Science.
In my own teaching I find myself increasingly shunning new Edtech tools, and now barely bother clicking on the links I receive in my inbox every day. Until Edtech startups really engage with teachers, rather than just treating them as beta testers, I really don't see anything in the future other than increasing fragmentation and frustration.
