Instructor diagnosis of pilot trainee errors was studied in the context of instrument flying using a computer simulation system called ORLY. ORLY was used to record student pilot runs on a number of instrument flying tasks. These runs were subsequently replayed to instructor pilots who diagnosed student errors and hypothesized the underlying…

Diagnostic/prescriptive mathematics was examined to ask whether a sufficient body of professional knowledge and practices exist to warrant its inclusion in teacher preparation. Argues that diagnostic/prescriptive mathematics does constitute an appropriate topic for consideration as content in revised teacher preparation programs. (PK)
