I regularly teach Git to students at the senior level that are building RoR applications. Even though we only cover the basics, they seem to struggle quite a bit with both the concepts and the mechanics. They are on Windows for the most part, and are required to push their code to Bitbucket. The seniors have suggested that I introduce the topic much earlier in the curriculum in a sophomore level Java class. The students in that class have had one prior programming class, but generally are still struggling with the basics. I've been thinking about using Mercurial at the sophomore level instead of Git to see if that eases the introduction to the concepts. Any thoughts one way or the other?

Sorry - should have been clearer. These are undergrads in a 4 year bachelor of science technology program. They are not CS majors, so they have limited programming background in general.

#4I guess that they are simply not accustomed to work in command line, given
that Windows gives terrible terminal and shell. I would rather expose them to
Linux (or maybe BSD), possibly through providing them shell accounts on some
server and requiring code to be built primarly there. Then it should not be
too difficult to jump from working with files in command line to working with
version control in the same command line.

You are definitely right that they are not comfortable in the command line. They do get exposed to it quite a bit in the curriculum, but not prior to the Java class. I have been using Vagrant in the senior class, and quite a few of the students end up installing Linux for RoR dev. It might be too much for the sophomores however.

Or it may not be too much. My whole university year was required to use some
unix variant starting with the first semester, where we learned C (so add
memory management and pointers arithmetic to things to learn, and I didn't
even start with mathematics we were taught at the same time; computer usage
was not the only totally new subject for us).
Of course I agree that it's not an insignificant load. Learning how to write programs at all is difficult enough, and what I propose is just adding learning new environment on top of it. On the other hand, a shell server with compilers and editors already installed may be a good start. This way students get stable environment which already works, so they can focus on learning how to use it instead of struggling with administering it.

If using the commandline is the main problem, why not use a git GUI interface? (Would Github's be of any use?)
I'm not saying learning the commandline is not important, but that would split the learning load so they only have to learn one new concept at a time (only cmd or vcs instead of both together).

#8On whether to use Git or Mercurial, my gut suggests you teach Git, but if you have the ability, poll alumns of the program and/or companies who are nabbing grads to see what they have/haven't used. Personally, I've never been around an environment that uses Mercurial, but that's just my particular situation.
Also, the basics of version control should be taught in the very first programming class. You can then expand on the basics in further courses.

My gut has been Git as well, since I have always used it in commercial development. My guess is that the companies the students are going to use Perforce or a commercial tool since most end up in energy / oil related companies that tend not to use open source at all. That said, I'll see if I can get more info on what they are using. I don't have control over the first class they take (yet) but I do agree with getting them started early. Most of the programs (CS,EE, etc.) don't even teach version control at all at the undergrad level, so I am doing what I can to remedy that issue.

>given that Windows gives terrible terminal and shell
Though the command set is a little verbose I think powershell is pretty nice. If you get posh-git(https://github.com/dahlbyk/posh-git) and use powershell it makes the git experience on windows quite pleasurable.
