Ms. Okafor knows something most education researchers don't: there are seventeen different reasons a student might not understand fractions, and each one requires a different approach. She figured this out over three decades of watching kids struggle and then not struggle.
She's retiring in June. She's made peace with it. What she hasn't made peace with is that all of it — the heuristics, the diagnostic questions, the specific ways she reframes a concept when the first explanation doesn't land — will have nowhere to go.
Her department head suggested something last fall. Over eight sessions, Ms. Okafor worked with a WisdomTwin interviewer to map out what she knew: not lesson plans, but the reasoning underneath them.
The result lives on school-issued tablets in her district. New teachers can open it when they're stuck. A student can open it when they're lost. The twin asks first and explains second — the way Ms. Okafor always did.
Ms. Okafor stops by the classroom sometimes. She likes knowing it's still working.
