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? Five reviewed studies report PBL improved vocabulary acquisition, including environment-related vocabulary and vocabulary in writing tasks. → Guo Qian 2024

q2 · i? · quant-synthesis · r2
Narrative synthesis of five studies (Studies 4, 5, 11, 19, 23) on vocabulary acquisition, including mixed-method and quasi-experimental designs. Study 23 combined PBL with VR and reported "significant improvements in vocabulary acquisition and increased motivation".
"Chen et al. [36] found that a PBL approach combined with virtual reality (VR) technology led to significant improvements in vocabulary acquisition and increased motivation among engineering students in Taiwan."
