1) give myself some structure in my only full month of summer vacation
Yeah, that worked out pretty well. I wrote some of these posts in the early morning around breakfast time, or at least they got started then. About half of the posts were prompted by "oh crap, it's about 8pm and I haven't written yet!"
2) encourage a "less is more" approach in my own blogging, after a string of very long submissions
This goal was somewhat successful, although some posts were fairly long. I split a couple of topics across two or three days, which helped me continue the challenge. That is a strategy I can use in future blogging (and should probably apply in the classroom too, instead of cramming topics/activities into a shorter timescale).
3) "think out loud" about where I want to take my classroom next year ... I'm on the fence between blowing everything up (TTOG, gamification...) vs. staying the course with minor tweaks
I did this a little less than I expected in the blog, although I've filled about 10 notebook pages with plans and ideas. More importantly, I succeeded in preventing myself from yet another system overhaul: no throwing out grades, no year-long gamification, none of the revolutionary thoughts I entertained in June.... I need a 'normal' year, and a chance to try out the ideas that never got a chance in 2016-17. I know the cool thing this summer is to Shift This! and I like/respect Joy Kirr's approach, but that's not the right thing for me now. Minor tweaks FTW!
4) connect with some other flipping bloggers by adding some links to their posts & starting/encouraging dialogue between us
This might be the best success of all, because the #flipblogs concept somehow emerged from my personal blogging challenge and some good-natured ribbing from Matthew Moore and Crystal Kirch.
