Study: Implicit Instruction Rated More Interesting Than Explicit Instruction

My Post I Wish You’d Read From Start To Finish

Marbleslides Madness!

Justin Brennan:

After spending 8 years as an engineer prior to teaching, I always felt that I’d include all kinds of stuff from my engineering life into teaching. However, now that I am slightly wiser and more humbled, that stuff is too specialized, only interesting to me and maybe 2 other kids on a good day.

2015 Remainders

Let’s close out 2015. In this remainders edition:

  • Eight new blog subscriptions from November & December.
  • Five essential 2015 posts from this blog.
  • Three bloggers I envy.
  • Seventeen Great Classroom Action posts I never got around to posting.


  • We successfully goaded Brett Gilland into tweeting and blogging. His writing features art, wit, and insight for days. Best follow of my fall quarter.
  • Jason D’Arcangelo is an elementary math coach, making him rare company online.
  • Kendra Lomax does interesting work in elementary math education also, most recently with the University of Washington’s Teacher Education by Design project.
  • Damian Watson just came off a two-year blogging hiatus with a post featuring Malcolm Swan, Andrew Stadel, and cognitive conflict, which pushes all three of my buttons.
  • Meryl Polak likewise came off a maternity leave to post about her experience designing and implementing a 3 Act Math task.
  • Geoff Wake was one of my colleagues at the Shell Centre when I set up a tent in their offices several years ago. Great guy. Interesting thinker. I’m excited to see him maintaining a blog.
  • Jenn Vadnais does consistently interesting work with the Desmos Activity Builder. I’m tuned in, hoping to learn how she works.
  • Glen Lewis blogs thoughtfully about technology, learning, and engagement in math education.

These blogs are each low volume, producing maybe one post per month. There is zero risk of getting overwhelmed here. Just toss them in Feedly or some other RSS reader and enjoy their insight whenever they find the time to share it.

Honorable Mentions

I don’t have a lot of envy in me for other Internet math ed types — their followers, retweets, subscribers, etc. Just keep working. What does turn me green, what I do covet, though, is another blogger’s ability to stir up conversation, to mobilize and collect the intellect of his or her readers. In 2015, that was Dylan Kane, the blogger whose posts invariably had me clicking through to the comments to see what he managed to provoke from his readers, then scratching my head trying to figure out how he did it.

If your heart belongs to elementary math education, the best moderators I have found there are Tracy Zager and Joe Schwartz.

My Year in Review

If you’ve come to this blog only recently, here are five posts that received a lot of traffic and commentary this year:

Looking for favorites from the wider online math education community? Check out the #MTBOS2015 hashtag. If I had to award my own MVP, it’d be Elizabeth Statmore’s “How People Learn” and how people learn where she turns essential research into manageable practice.

Great Classroom Action

And now, shamefully presented without commentary, seventeen posts I read in 2015 that had me check myself and think, “That classroom action is great!” I haven’t shared these yet and it’s time to clean the cabinet.

October Remainders

Quality over quantity this last month. Still, I could use a little more quantity. Let us know your new subscriptions and follows in the comments.

I’m bringing this feature back on the encouragement of Tracy Zager and because I ought to have more to show for the truly inappropriate sums of time I spend trawling the mathtwitterblogosphere.

New Blog Subscriptions

  • Patty Stephens is an instructional leader in Washington state. I’m hoping she writes more about her Teacher Fellows program, which attempts to build teaching capacity throughout the state. (Ditto Bryan Meyer about his Teacher Partnership Program, while I’m here.)
  • Bridget Dunbar has been blogging and tweeting for years but left her first comment on my blog last week, pointing me to her exceptional post comparing the pros and cons of three representations of the same problem.
  • Ryan Muller is a software developer who writes about education research at his Learnstream blog. He seems curiously unaffected by education research’s typical turf wars, just happy to read and write about what he reads. Refreshing.
  • Timothy McEvoy writes thoughtfully and critically about math edtech, a genre of writing that is in short supply.
  • Tom Bennison runs the #mathsjournalclub chat on Twitter — a discussion group for math education research, which is the kind of social unit I’m already missing from grad school.
  • Julie Reulbach offers us all a daily photo and caption from her innovative algebra classes. Yes, please.
  • Kris Boulton applies our headache metaphor to a question about slope. Watch how his subtle alterations to the same task make its mental controversy more acute. More like this, please.
  • John A. Pelesko and Michelle Cirillo are a university-level mathematician and math education researcher, respectively, and have paired up for a blog dedicated exclusively to mathematical modeling! Their post “Is this mathematical modeling?gets it.
  • Sam Shah’s new group blog around good questioning strategies had me at “Sam Shah’s new group blog.”
  • Nathan Kontny writes breezy narratives about entrepreneurship, at least one of which (on audience) is still rattling around my head one month later.
