Reddit reviews How People Learn: Brain, Mind, Experience, and School: Expanded Edition (Informal Learning)

Sounds like you are in a similar boat to what I was a few years ago. I'm now in my 4th year of teaching high school CS, and loving it! This will be my second year teaching at a private school in Chicago, and the demand during my job search last year was very high. I know that's still true of private schools, and the same for public schools here, with the new CS for All requirement. In my experience, many private schools will hire you with just an undergrad degree and some kind of teaching related experience, without the need for any formal education certification to get started. Although public schools really have a need for CS educators right now, private schools might be worth looking into, as there are typically fewer formal requirements. I'd recommend taking any opportunities to get some teaching experience that you can get, whether more camps, tutoring, being a teaching assistant, etc, as that will help you get started either way.

So demand is high and the job is challenging but very rewarding. Salary is, perhaps understandably, less than what you'd make doing a lot of programming jobs. I'm confident that I would be making significantly more money as a software developer, but I didn't find that kind of work to be what I enjoyed.

As you start looking into this, I'd recommend getting familiar with the typical high school curriculum. The standard courses at many schools tend to be AP Computer Science Principles and AP Computer Science A. AP CS A is an object oriented Java course, similar to many first semester college courses, but AP CSP is much more broad and less about just programming. You can find the AP CSP curriculum information on its site. Some common pre-made curriculums for that include Code.org, BJC, Mobile CSP, and a few more. You might also take a look at the K12 CS Framework, which many schools are using to guide their curriculum, to see what kind of stuff is valued in high school CS programs. Other good resources are the Computer Science Teachers Association (CSTA) Website and as someone else mentioned, SIGCSE. Both have conferences that I've been to and would highly recommend.

In terms of teaching and lesson planning, there are a ton of books I've found useful. A couple of general purpose standouts on learning science, lesson planning, classroom management, etc include How People Learn and McTighe's stuff on Understanding By Design (a lesson planning idea) like this one.

Happy to answer other questions if you have them, too! CS Teachers are seriously needed all over the place.

how people learn is one that was used in my undergrad psych program at ucla, and again in my credentialing program (again, through ucla).

are you looking at it from a cognitive or biological point of view?

That's a big question that can't just be answered in a reddit post. A good introduction and thorough overview is Bransford's 'How People Learn'.
