Definition of abbreviation: SD = standard deviation.
*
Difference in knowledge gain between the self-reliant textbook study and the instructional training group (F = 8.811, df = 1, P = 0.007)
†
Difference in skills gain between the self-reliant study and the training group (F = 33.965, df = 1, P < 0.001)
