…a day in the life

“That angle you’re using is risky. Can I show you a better one?”

Why practice what, when, how?

Why?

meaningful dataLearner performance, attention, stress, recent patients, etc.

Scenario/item properties

Why?

smart sense-makingMachine learning…or, simpledecision rules

Why?

Effectivelearning theories

• Zone of proximal development (“flow”)

• Desirable difficulties

What?

individualknowledge/skill/practice gaps

(see “mastery learning”)

When?

at each learner’s“sweet spot”

but takes effort.

How?
