Abstract To address the pedagogical challenges in the traditional copper sulfate crystal preparation experiment,invisibility of crystal growth,difficulty in controlling experimental conditions,and oversimplified assessment,a digital experimental system was constructed by integrating microchemical technology and digital microscopic imaging.This system enables precise regulation of crystallization conditions,real-time capture and recording of the microscopic dynamics of crystal growth,and establishes a data platform for comparison and analysis.The study finds that the system achieves visual presentation and parametric analysis of the crystallization process,allowing students to intuitively establish quantitative relationships between experimental conditions and crystal morphology as well as growth kinetics.Teaching practice demonstrates that this mode transforms the traditional operation-oriented experiment into a data-driven inquiry process,effectively enhancing students’ abilities in experimental design,process analysis,and scientific thinking.It promotes the digital transformation of experimental teaching from outcome-oriented to process-oriented,and from experience-based judgment to data-supported methodology,thereby providing a replicable solution for the modernization of classic chemistry experiments.
