Abstract To address the contradiction between high cognitive demands and low learning efficacy, this study implements a four-dimensional synergistic deep lesson preparation mode, integrating knowledge deconstruction, learning analytics anchoring, instructional design, and value integration, in physical chemistry education. Teaching practice spanning 11 cohorts(2012-2023, N=689) demonstrates that deep preparation significantly enhances academic outcomes during full implementation(2017-2019 cohorts):average scores increase by 12. 8%(p<0. 001), standard deviation decreases by 42%, and low-score outliers reduce by 76%, with 46% of the 2017 cohort opting for postgraduate studies in physical chemistry. The 2018 cohort achieves a peak average score of 84. 91(95% CI:83. 9~85. 9), exhibiting a leptokurtic distribution. The mode’s innovation repositions the core of pedagogical reform onto systematic, evidence-informed preparation, leveraging data-driven design and blended instructional techniques to scaffold the transition from abstract knowledge to applied engineering competence.
