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? Across three reviewed studies, students in problem-based learning environments significantly outperformed comparison groups (instructor-led or lecture) on CT skills. → Dawit T. Tiruneh 2014

q2 · i? · review · r3
Synthesis of the review of three PBL studies, in which problems were addressed through small group discussion without explicit CT instruction. In Sendag and Odabasi's online PBL study, the PBL group "significantly outperformed" the instructor-led group; the other two studies also found PBL groups significantly outperformed lecture groups.
"They found that students in the online PBL group significantly outperformed those in the online instructor-led group."
Discussion¶
Learner Variables¶
- Critical Thinking — outcome: instruction changes it
Related Claims¶
- Direct CT instruction combined with modeling, coaching, and discussion yields more consistent CT improvement than implicit teaching strategies — reports the opposite
- Inquiry-based learning strategies in laboratory courses are reported to significantly improve critical thinking skills — related
- AI-supported PBL students obtain significantly higher posttest computational thinking scores than traditional-lecture students when controlling pretest scores — related
- Student engagement is higher during PBL than during traditional instruction — related
- AI-supported PBL students obtain significantly higher posttest academic achievement scores in robotics programming than traditional-lecture students when controlling pretest scores — a narrower finding that bears on this claim
- The scope of PBL implementation shaped discussion quality: hybrid lecture-based implementation reduced uncertainty but yielded less critical discussion than full PBL — related
- Effects of P(j)BL on CT are mixed across studies, with positive, null, and negative findings reported — reports the opposite
