A new question has again raised the issue of the scope on our site.
In this case it's about some possible form of internet blocking affecting the student access to resources. Other questions which we have dealt with include classroom layouts, monitoring student screens, note taking, blackboards vs. high-tech tools, Smart Boards, letters of recommendation, an in-house server, hardware choices, and version control setups.
In many cases we have seen questions which would be "in scope" for other sites and have kept them here. The SE rules do not require that a question be on-topic on exactly one site, not that our scope be exclusive to this site, refusing questions which might be better asked elsewhere.
The question addressed here might have gotten answers, or good diagnostic hints, on Super User or Server Fault. It also may have been rejected by either site as off-topic. The issue of a question's topicality here should not be a function of its topicality elsewhere. Rather, the decision should be based on our site's determination of our scope.
It does not seem like an expansion of scope to accept that question, or the others mentioned. Classroom management, student engagement, technical issue, and many other subjects are involved in teaching CS. Some of the issues faced may be common to teaching in general, yet have a twist when applied to the CS field. Others may seem more like a question better suited for programmers or computer scientists, yet have a twist when applied to the classroom. In both cases, while an answer might be forthcoming on a sister site, the answer could be less useful than if the environment of a CS classroom is considered in the problem. Taking that extra element into consideration is something which we can specialize in.
I do not believe, however, that the mere coincidence of an issue involving a CS classroom, or educator, at some level makes any question automatically on topic. "How to replace the hard drive", or "How to configure the network in the classroom", as examples, are not going to have any significantly different answers because there is a CS classroom involved. How to replace the computer's disk drive is pretty much the same at work, at home, in the classroom, or in a cave. Ditto for running cables and connecting computers to a network, or a virtual LAN. "How to configure the classroom server", however, might be different for the CS classroom than for other classrooms, or the office.
The question, "Do some websites block school building/classroom IP networks because they mistake us for possible DDOS?" is one I consider on topic for Computer Science Educators.
