Not really. There is an online MS in Computers Science from Georgia Tech, that's really well regarded and will cost you approximately $8,000 for the whole degree.
A lot of materials science is highly experimental, so it's not super easy to teach advanced skills. I went to a top 10 materials science school for my PhD, and the absolute vast majority of what I learnt was self-taught. However there is a caveat - I self-learnt by doing, and failing multiple times. The advantage of a high ranked school is that the research facilities are top notch and professors bring in external grants, so the research facilities are always maintained at a high standard through overhead costs.
There is also a lot of value in the conversations you have with other students and faculty something that is really hard to reproduce remotely. It's also something where quality matters, I suspect.
Could you supply some examples? I know of Western Governors University, but it only has limited majors.
In particular, do you know of any online degree programs in materials science?
