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.

q3 i3 Problem-solving effects are significant for ≤5 weeks and >5 weeks, RCTs and quasi-experiments, small and large samples, and sophomores and seniors, but not third-year students (SMD = 1.74, P = 0.15). → Zou Ya 2026

Evidence¶

Zou Ya 2026¶

Zou Ya, Xie Wenzhao, Huang Hui, Liu Dan, Zhou Qing, Yi Qifeng, Tong Xiaoliang, Mao Ping. (2026). The effects of case-based, problem-based, and team-based learning on nursing students’ problem-solving, self-directed learning, and communication skills: a systematic review and meta-analysis. BMC Medical Education. https://doi.org/10.1186/s12909-026-08602-3

q3 · i3 · quant-synthesis · r3

Study-design subgroup analysis for problem-solving abilities (Table 4): both RCTs and quasi-experimental designs show significant effects, with a larger point estimate in RCTs. Duration, sample-size, and grade subgroups are also reported as significant except third-year students.

"the subgroup analysis revealed that both RCTs (SMD = 1.08, 95% CI: 0.27–1.78, I2 = 96%, P < 0.001) and quasi-experimental studies with control groups (SMD = 0.51, 95% CI: 0.11–0.83, I2 = 93%, P < 0.001) demonstrated that modern teaching methods could significantly enhanced the problem-solving abilities of nursing students, although the effect size was larger in RCTs"

q3 · i? · quant-synthesis · r3

Grade subgroup for problem-solving (Table 4): third-year (junior) students show no significant effect, with very high heterogeneity ("I2 = 97%").

"the third-year students did not (SMD = 1.74, 95% CI: -0.65-4.13, I2 = 97%, P = 0.15)"

Discussion¶

Learner Variables¶

Problem Solving — moderator: an instructional effect differs with it

Modern teaching methods significantly improve nursing students' communication skills (SMD = 1.80) — related
Modern teaching methods significantly improve nursing students' problem-solving abilities (SMD = 1.05) — a broader claim this one bears on
Communication-skill effects of modern teaching methods are significant only for short durations (≤5 weeks) and second-year students — related
ECE benefits both junior and senior preclinical dental students, with a larger pooled effect in junior students — related
