Abstract: To address the prevalent issue in analytical chemistry laboratory instruction that overemphasizes result compliance while neglecting procedural standardization, our teaching team implemented a teaching practice incorporating standardization principles into the curriculum. At the content level, we developed unified teaching protocols specifying key concepts, instructional logic, and operational standards. The practical implementation features an immersive “virtual simulation + student self-assessment” hybrid model, effectively transitioning students from passive imitation to active standardization compliance. Pre-laboratory pilot studies were conducted to mitigate potential instructional risks, accompanied by established evaluation metrics. Our assessment framework emphasizes process-oriented evaluation, with detailed scoring rubrics for both operational procedures and data quality to reinforce standardization throughout the experimental workflow. This pedagogical practice has demonstrated significant improvements in students' operational standardization and data reliability, while enhancing overall instructional quality in analytical chemistry laboratories, offering valuable insights for experimental course reform.
