When subgoal location was appropriate to the serial pattern, subjects were likely to use a strategy resulting in enhanced rule induction and transfer with increased subgoal density. When subgoal location was not appropriate, subjects tended to use a strategy resulting in considerably reduced role induction and transfer. (Author/PN)

Mastery learning techniques were improved through mathematics instruction based on a validated learning hierarchy, presenting tasks in a sequence consistent with the requirements of the hierarchy, and requiring learners to demonstrate achievement before being allowed to proceed. (Author/GDC)
