The model consists of five stages: Empathize, Define, Ideate, Prototype and Test. Taking the high‑school‑biology practical project “self‑built PCR thermocycler” as a carrier, teachers guide students to integrate multidisciplinary knowledge to complete the design, fabrication and functional verification of a PCR thermocycler. Students’ interdisciplinary literacy advances gradually at the knowledge, thinking, practice and affect levels, and students transform from “instrument users” to “innovative designers”.Design thinking, Interdisciplinary literacy, Self‑built PCR thermocycler, Secondary school biology experimental teaching
