Abstract: Fundamental operation instruction constitutes a vital component of chemical laboratory education. This article delineates the pedagogical explorations and implementations by the Basic Chemistry Experiment Teaching Group at Wuhan University in fundamental operation training. The team has established a five-step closed-loop instructional model that concurrently develops technical skills and critical thinking abilities, thereby transforming the teaching paradigm from “unidirectional delivery” to “cyclical refinement”. This methodological framework serves as a crucial mechanism for ensuring consistent enhancement of instructional outcomes.
