Learner Preferences and Achievement Under Differing Amounts of Learner Practice.
Peer reviewed Peer reviewed
Schnackenberg, Heidi L.; Sullivan, Howard J.; Leader, Lars F.; Jones, Elizabeth E. K. – Educational Technology Research and Development, 1998
Examines the effects of program mode (i.e., a lean program version containing a basic amount of learner practice versus a full mode containing expanded practice) and learner preference (matched or unmatched) for amount of practice on the achievement, time-in-program, and attitudes of university undergraduate students. Students preferred the lean…
