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? In one included study, second-year students did not exhibit improved performance compared to first-year counterparts after bilingual instruction, and the authors invoke the Threshold Hypothesis as an explanation. → Ji Pengyu 2026

Evidence¶

Ji Pengyu 2026¶

Ji Pengyu, Li Qianqian, Li Na, Zhang Lin. (2026). The efficacy of bilingual immunology teaching on undergraduates in China: a systematic review and meta-analysis. BMC Medical Education. https://doi.org/10.1186/s12909-026-08725-7

q2 · i? · quant-synthesis · r1

The review reports, from one included study spanning multiple academic years (300 first-year and 180 second-year undergraduates), that sophomores did not improve relative to freshmen, prompting separate cohort meta-analyses. The authors attribute this partly to sophomores having reached the required English proficiency threshold.

"The findings revealed that, following bilingual instruction, second-year students did not exhibit improved performance compared to their first-year counterparts. Consequently, separate meta-analysis was conducted for each cohort."

Discussion¶

Learner Variables¶

English-Learner Status — moderator: an instructional effect differs with it
Reading and Language — moderator: an instructional effect differs with it

Teaching students in a language they understand benefits both language learning and broader learning — a broader claim this one bears on
Low English proficiency screener scores in pre-k relate to lower academic performance but not to attendance — related
Evidence for bilingual immunology teaching rests on few, mostly moderate-quality non-randomized studies with substantial heterogeneity — related
Bilingual immunology teaching significantly improves undergraduates' competence in English application — related
