"In every case where we implemented check-your-understanding questions, 15%-50% (usually 15%-25%) didn't do them. This sounds bad. But on the flip side, this meant that 50%-85% (usually 75%-85%) of students were doing the questions, and doing them for he right reason and for the right person."
--Peter Liljedahl, Building Thinking Classrooms in Mathematics, p. 125.
Is It A Battle Worth Fighting?
The first time I read the chapter on homework/practice/check-your-understanding questions, my main takeaway was that Liljedahl's research and advice were intended to convey the message that homework might not be a battle worth fighting. Certain negative outcomes, he found, were prevalent when practice problems were checked, certain other problems were prevalent when it was not checked, and the fewest problems were prevalent when they were re-branded as Check-Your-Understanding Questions (CYUs) and answer keys were provided.
In the grand scheme of things, I've chosen to surrender. I assign check-your-understanding questions (CYUs) as prescribed. I provide answer keys as prescribed. I don't check them as prescribed.
By the book. And a bunch of the kids don't do them. But... There's more to love about check-your-understanding questions than meets the eye. BTC says "Thou ShalL Not Check" when it comes to CYU's, but it Never Says "Parents Shall Not Check"
I love this joke from comedian Daliso Chaponda where he says, "the Bible says you shall not steal, but nowhere does it say you shall not swap."
Nobody loves a good technicality more than I do.
Admittedly, however, increasing completion isn't my main motivation for adding that guardian signature line to my CYU's.
The bigger reason is that I have this at the ready whenever we have a parent-initiated "why isn't Suzie doing better in math" parent-teacher conference. "Why don't we start by looking through Suzie's math binder and seeing how often she is getting her check your understanding questions done and signed. While she gets the binder out, how is that nightly check in going? Quite well, I've presumed, since you haven't emailed me that she doesn't understand it in quite some time." *Flips through Suzie's binder* "It would appear that we aren't taking advantage of all the opportunities to stay on track right now, so why don't we start there before we look into anything extra for Suzie." The CYUs are my CYA, if nothing else. CYUs Free Me Not To Make Study Guides
At younger grades, where I've spent the bulk of my teaching career, parents loathe homework, but they love study guides.
And CYU's are my permission not to make them.
CYU's are a great "closing Activity" option
Liljedahl refers to consolidation, note-making, and check-your-understanding questions as "closing activities." They the activities intended to help a student move from a messy, group-based understanding to a tidier, individually-owned understanding.
I plan all three every day. I don't always get to all three every day, but I plan them. I'm also starting to inch my way toward more flexibility with which ones I use each day and how. There are days where the thinking tasks goes so well, and I can manage everything through hints and extensions well enough that we don't need to consolidate. I also have - and have always had - a complicated relationship with notes. And to be honest, most of my students avoid the note-making practice as much as they avoid the check-your-understanding questions. Most 6th graders aren't using notes after making or taking them, so I often question why we spend so much time giving them notes in traditional classrooms, or providing time to make them in Thinking Classrooms.
Retrieval Practice > Check-Your-Understanding Questions
One of the biggest reasons I don't stress about the fact that most of my students aren't doing CYU's is that, frankly, they're learning at high levels without them.
One of the biggest reasons that they're learning at high levels without them is that I start every day with a heavy dose of retrieval practice. CYUs are all about memory. The thinking tasks is designed to build understanding, consolidation and note-making are designed to formalize the vocabulary, conventions, and organization behind that understanding, and CYUs are designed to help students remember the skill and move the student toward automaticity. CYUs, then are designed to combat the inevitability that is... forgetting. I write often that forgetting is normal, that we should expect it, that we should teach students how it works, and that we should build systems that make forgetting and remembering a guilt-free, routine experience in classes of any sort. Since forgetting is predictable, we know much about predicting it. Namely, we know how quickly and how often we should deal with it:
Retrieval practice is a must. We're going to need to do it whether kids did their CYUs or not. The kids who did, we would expect, will have a 15-20% head start, but that's it.
In truth, if memory is what we seek (and it should be), retrieval practice is far more effective for getting there than CYUs or traditional practice sets. When it comes to affecting long-term memory, retrieval practice > check your understanding questions. TLDR - So what's the Plan?
In summary, even though the lack of CYU completion still frustrates me, I've built a system where the kids still do really well. It goes like this.
Frankly, that's it when it comes to CYUs. That said, there are a few more details and some downstream thinking that go into that system, too:
Winston Churchill often quoted as having said "democracy is the worst form of government, except for all of the other ones." An easy way to summarize Liljedah's chapter on check-your-understanding questions, I think, is unchecked CYUs are the worst system for homework and practice, except for all the other ones. The kids aren't doing the check your understanding questions! I know they're not. And I'm not stressing about it. Because they're learning at high levels anyways. In the end, I've just accepted it and reallocated my time, effort, and frustration to the other practices.
