Compared to traditional instructor-led training, computer-delivered trainin
g typically offers learners more control over their instruction. In learner
-controlled environments, learner choices regarding practice level, time on
task, and attention are expected to be critical determinants of training e
ffectiveness. To examine the effect of learner choices in computer-based tr
aining, a study was conducted with 78 employees taking an Intranet-delivere
d training course. Learner choices were assessed and predicted with goal or
ientation (mastery and performance) and learning self-efficacy, as well as
age, education, and computer experience. Results indicate considerable vari
ability among trainees in practice level and time on task, which both predi
ct knowledge gain. Performance orientation interacted with learning self-ef
ficacy to determine practice level, and mastery orientation had an unexpect
ed negative effect. Implications for the use of computers to deliver traini
ng and for future research are discussed.
