In regard to suggesting alternatives, here is a thought: Since educational institutes use software in almost every category,it is not possible to suggest all the alternatives. Every field might have very specific type of software requirements to do the job.
Some fields of education require a lot of software, some do not depend on software at all. Theoretical mathematics require no software at all. Electronics, Computer Science etc. probably require a lot of software. I think we can only give basic level alternatives like for hosting lectures, uploading notes, videos, recording classes etc.
In addition, they should teach students the concept of free software as well.
