摘要： 为解决当前分析化学实验教学中常出现的“重结果达标、轻过程规范”问题，本教学团队开展了将标准化理念融入分析化学实验课程的教学实践。在内容层面，教学团队制定了统一教案，明确了教学重难点、讲解逻辑及操作规范；在实践层面，推行“虚拟仿真预习+学生自查”相结合的沉浸式教学模式，助力学生从“机械模仿”转变为“主动规范”。同时依托预实验以规避潜在教学风险，配套提供评分标准；在考核层面，以过程性评价为核心，细化了操作与数据结果的评分标准，引导学生重视实验全流程的标准化。教学实践表明，该方法不仅提升了学生实验操作的规范程度与数据质量，还改善了分析化学实验教学的整体质量，为实验课程教学改革提供了有益思路。

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.
