Ask HN: Opinions on cheating and modern computer science education

So it turns out that I'll be teaching a pretty typical CS course this coming fall at a local university as a part-time professor. I have some time to consider how I want to structure the course before I review my plan with the department. So I was hoping to get the HN community's take on two things that I am having a hard time balancing in my plan:

    - Improving learning and modernizing classroom procedures
    - Preventing cheating

Basically, I'm interested in the possibility of using Git, Github, and a CI testing service to deliver, collect, and (at least partially) grade assignments via the most commonly used VCS workflow used by projects hosted on the platform. That is: everyone forks, pulls down, pushes up upon completion, submits PR for testing/review.

Overall I like the idea because it would expose them to these basic workflow & development lifecycle concepts early. Later, if they take well to it, I would like to explore creating assignments that are multi-stage and legitimately collaborative between me and them (perhaps organized into small groups). I think there is a lot of potential for learning there. And the platform removes a lot of the tedious parts of the process on my end.

But, there is a pretty big catch to running a course my preferred way though: other students will see each other's pull requests (ie. their completed assignments). In the minds of most faculty, the concern is that this would promote cheating. Academic integrity is something institutions need to protect to ensure the future value of their degree offerings, and enforcing individual assessments of all learning objectives is the way used to achieve that.

The on-again-off-again professor in me agrees with that, but the working software engineer in me is a lot less sure.

Any thoughts on this from the software professional side of the tracks? I'm asking the same to other professors that I know as well. I'm interesting in contrasting the two perspectives.
