Self-Directed Learning In Problem-Based Learning: A Meta-Analysis, Heather Leary, Andrew Walker, Brett E. Shelton
Heather Leary, Ph.D.
This paper presents a meta-analysis focused on self-directed learning in problem-based learning when compared with a traditional learning approach. A total of 75 outcomes from 38 studies were used in the analysis which resulted in a statistically significant overall medium effect size of g = 0.45, favoring problem-based learning. Subgroup analyses conducted focused on four aspects of self-directed learning. Both personal autonomy (g = 0.51, z(47) = 6.4, p = 0.01) and independent pursuit of learning (g = 0.66, z(2) = 3.49, p = 0.01) report statistically significant positive effect sizes. Three of eight disciplines reported statistically significant effect sizes …

Problem based learning (PBL) in its most current form originated in Medical Education but has since been used in a variety of disciplines (Savery & Duffy, 1995) at a variety of educational levels (Savery, 2006). Although recent meta analyses have been conducted (Dochy, Segers, Van den Bossche, & Gijbels, 2003; Gijbels, Dochy, Van den Bossche, & Segers, 2005) that attempted to go beyond medical education, they found only one study in economics and were unable to explain large portions of the variance across results. This work builds upon their efforts as a meta-analysis that crosses disciplines as well as categorizes …
