Hi! I think it's hard to generate actionable data using SBG. For example, the article you linked to suggests making better multiple choice (MC) items. But MC is a deal-breaker for me. 10 MC items gives me less insight into student thinking than 1-2 free response questions with work shown.

Do you happen to recall which one your students found to be the easiest? Here's what I've got for #15, though I've only done the problem transformationally at this point. Really follows nicely from our review of functions in Precalc Unit 1.

@mattryanelateach.bsky.social Want to talk about Daniel's post? I actually think that doing more of what that class teaches is one of the necessary solutions to the replication crisis in social sciences.

I've never introduced the definition of radians by having students calculate arc length. That's nice! Very cool.

Apparently technology might literally cause the brain the use a different network of neurons that causes students to think more intuitively but less deliberatively?

Leaders performing symbolic or rhetorical acts probably increase demoralization. Dems need leaders to step up who can make things happen in the real world. We need folks who can show flexing the power we still have. Even if it has little effect. To remind our side we've still got tenacity & wit.

Regarding demoralization, I'm reminded of how Churchill suddenly reversed Londoners' demoralization by having antiaircraft crews blast away ineffectually during the Blitz, just so folks knew their side was firing back. From Erik Larson's The Splendid and the Vile:

I like what you're saying, but I think you're describing what good teaching looks like once you get out of the "logic" unit and into the real content. I'm asking how we can do better with the unit that comes before that content: the formal logic unit. It's too disconnected from future material.

Or students can write an equation that uses a given theorem to express what's shown in a diagram. Like:
Given: "If two angles are same-side interior angles of each other, then they are supplementary."
Given: In the picture, the marked angles are same-side interior angles.

I guess I'm amplifying this part and adding that it's not just a matter of skill but also resource allocation. If fidelity matters to you, you have to put resources into making it feasible. I hope I'm not thread-jacking, but here's a quick example.

I don't know if the fine print would allow something like this, but sometimes its' cost-efficient to put in something like this new park in Hoboken, NY to keep the water out of people's homes.

Pre-pandemic, I would have said that this result was bogus even with their cherry-picked students. But the pandemic showed that for the kids they're serving, absence of instruction had little to no effect? Does this affect anyone's sense of instructional practice?

That's where Dan's post showed me how disappointing Unbound Academy's results seem to be. Their student-teacher ratio is actually lower than most public schools'. This is not the kind of system I could let run in the corner of my room while I'm conducting interventions and having kids work.

I love this paragraph from @dylanpkane.bsky.social's post about conceptual learning. One of my big criticisms of the IM curriculum is that they don't smear topics over 1-2 weeks like this. Smearing is better!

Sorry, I was reacting to the decline of the average score, not difficulties with the lowest scores. If the narrative from the article is on target, that would be bad imo:

This graph is pretty brutal. Do you think maybe there's pressure (impacted by Covid) not to leave the weakest students behind, and therefore teachers are teaching less content?
