About Debrief
You don't really know it until your explanation survives a question.
Debrief is a teach-back tool. Instead of grading you, it acts like a sharp, curious friend: you explain something out loud, and it finds the one spot where your understanding gives way. Then it helps you fix it.
The idea
Learning happens when you generate, not when you review.
Decades of research on retrieval practice and generative learning point the same way: you learn by pulling an idea out of your own head and putting it into words, then checking it against reality. Not by reading it one more time.
Debrief is built as that loop. It asks you to explain from memory, reveals a specific gap instead of a grade, gives just enough instruction to close it, and asks you to use the repaired idea in a new situation. Diagnosis and teaching stay separate, so you never leave with only a judgment.
What Debrief believes
Explaining reveals the gaps
Rereading feels like learning but hides what you don't know. Producing an explanation from memory forces the gaps into the open, where they can be fixed.
Diagnose, then teach
A grade tells you nothing you can act on. Debrief finds the one sentence where your reasoning breaks, then teaches to that exact point, not the whole topic.
Understanding is a thing you watch move
Every claim your explanation carries has a state. As you answer, you watch it shift from unclear to solid. Progress you can see, not a score you're handed.
Most tools tell you whether you were right. Debrief shows you where you stopped being sure, and stays with you until the explanation holds.
