Somewhere in Oklahoma there is a school district that needs to review its hiring practices.
I have been having thoughts about switching careers and focusing more on technology in the private sector.
I'm wondering if those thoughts were prompted by others.
I've changed directions in the generic "IT" field a few times, and it all boiled down to "What do I actually WANT to be doing? What am I doing in my spare time in IT that is distracting me from my day job?" I then enter that field, already having experience and connections in the sub-field that I want to be working in.
So for him, I think the question is, "What am I enjoying teaching right now? What do I dig into in more detail at home after I've done my prep work? What do I spend extra time helping students with?" In those areas, start hanging out on online forums and discussing your passion areas with likeminded techies. Find out about what's happening there in the private sector.
Leverage what you know and what you like; if you don't like what you're doing (that doesn't seem to be the case), then retrain yourself. This is important: in IT, you need to be constantly learning new things; taking courses and getting credentials comes at the end, after you've got some experience under your belt -- the creds are to prove you know what you're doing, not to train you how to do it.
Since you don't have any programming languages, you obviously haven't got a CompSci degree, so you're looking at "lower" IT work (services, not design). This means that you'll likely be working for lower wages, and need a lot of on-the-job training.
So, start at helpdesk, find out what you like and don't, and work your way up inside a company once you've got the experience under your belt. As you have teacher training, working with customers and explaining things in simple terms shouldn't be difficult -- working from a script may bore you to death however.
