Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? Meta-analytic research synthesized qualitatively indicates PBL outperforms traditional instruction on long-term retention measures. → Strobel 2009
Evidence¶
Strobel 2009¶
Strobel, J., & van Barneveld, A. (2009). When is PBL More Effective? A Meta-synthesis of Meta-analyses Comparing PBL to Conventional Classrooms. Interdisciplinary Journal of Problem-Based Learning, 3(1). https://doi.org/10.7771/1541-5015.1046
q2 · i? · qualitative · r?
A qualitative meta-synthesis of prior meta-analyses comparing PBL with traditional instruction. The synthesis reports that "PBL was superior when it comes to long-term retention"; no pooled effect size is printed in the available text.
"Findings indicated that PBL was superior when it comes to long-term retention, skill development and satisfaction of students and teachers"
Discussion¶
Learner Variables¶
- Long-Term Memory — outcome: instruction changes it
