This article contains an interesting graphic of an institution’s investment in software, comparing commercial and open source. The differences in planning and training, it seems to me, explains a whole lot about how technology is implemented in educational settings these days.
This article also contains what I think is a very pithy explanation for why so much commercial educational technology sucks:
“…education has been treated as a market of learning rather than an environment for learning.”
[emphasis in original]
Once again, it becomes clear how utterly inappropriate it is to apply capitalist models to education.
