Why does highlighting feel so productive, and why does it help so little?
We wrote up what the research says, footnotes included, and how it shaped Parlor.

The bit about "and" is what I'll keep: it says two things happened, not that one caused the other. The waterfall answer has the knowledge and none of the causation. Splitting a pupil's own run-on into lines and asking which causes which makes that easy to see.
Replying to @EnserMark
The second waterfall conversation is the one that fools everyone, the pupil included. Useful that you flag the check as an untested rule of thumb; it makes the rest easier to trust.
891 students' take-home exams: those who wrote their own answer first and then asked AI for feedback got the highest grades. Those who handed the work to AI did worse than students who didn't use AI at all.

The point about conversation being cued stuck with me. "So what happens at the bend?" already does half the retrieval. Looking forward to the "say it out loud with no help" test in part two.
Parlor Study asks you to explain what you read in your own words, then tells you which part of your explanation is off. Lecture notes, concept maps, and book discussions for the classics. Web preview by invitation: parlorstudy.com/?utm_source=…

The hard part is that the finished work looks fine, so grading the output can't show it. Asking for one step explained in the student's own words usually does.
Replying to @teacherhead
What makes cold call work is that everyone has to prepare an answer, not just the student who gets called. The same is true when studying alone: explaining it in your own words beats rereading because there's no one to hide behind.
A student explains a 95% confidence interval. The first half is right. The last sentence quietly turns it into "95% of students fall in this range."
Parlor's feedback points to that sentence, says what's right, and asks for one revision.
