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.
