I wonder, if the distance teachers are willing travel to learn after leaving University diminishes over time.
Take technology out the loop [the thing that brings learning ridiculously close] and consider the teaching strategies re-thought, re-worked or added to over time. Do teachers, once they get the job that most suits their lifestyle – close to home, fits in with their kids lives etc. – simply let themselves go? I don’t mean bludging, not caring or not meeting the job requirements — but stop being life long learners, happy to have achieved an orbit. If so, I wonder what triggers someone to get back on the road.
I can’t figure out why some teachers will create amazing resources and push the envelope, while others stop learning and start complaining. After all there are material costs not benefits to working at night on the hidden-curriculum.Yet those who are giving up more time and spending more money do it despite the lassitude of others and inertia of their environment. Mmmm, spiky Friday thoughts. If you have time, I’d love to hear from anyone about why they decided to keep edu-fit.
Playable 
I guess I do it because I feel a higher sense of purpose. Our responsibility is huge. Also, it makes me excited about seeing kids and they get excited about seeing me and that makes teaching fun.
Maybe they stop thinking of their career as a series of projects, and see it as a continuous job.
If you see teaching like an office job (I’ve done both), it is a daily grind. Skills are learned only to make the job easier, rarely to make it more interesting.
If you see teaching as a series of projects (each semester is a project), then there is a repeating opportunity to improve, to fix things, to make it better. I complain too, for sure, but my complaints are almost immediately followed by “next semester, I’m gonna try….”
