摘要：

为了提高实验课程教学效果，提升学生的学习兴趣，培养学生的科学探索精神，充分利用线上教学平台辅助分析化学实验教学。以“维生素C饮料中抗坏血酸含量的测定”实验为例，建立线上线下深度融合的实验课教学模式，优化整个实验教学过程，记录学生的学习过程，改进实验成绩评价方式。该模式可以激发学生的实验热情，使学生的学习由被动变主动，满足学生个性化的学习需求，还有助于培养学生的严谨的科学态度、安全环保意识和实践创新能力，从而实现创新型人才培养。

Abstract:

To improve the effectiveness of experimental courses, enhance interest, and cultivate scientific exploration, an online teaching platform is used to assist with laboratory teaching of analytical chemistry. This study uses the experiment "Determination of the ascorbic acid content in Vitamin C drinks" as a model to establish an experimental teaching approach that thoroughly integrates online and offline modes, optimize the entire experimental teaching process, record the learning process of the students, and improve the method of evaluation to determine the experimental grade of the student. This model can stimulate students' enthusiasm for experimentation, change the learning experience from passive to active, meet personalized learning needs, and assist in creating a rigorous scientific attitude, safety and environmental awareness, and practical innovation ability among students to nurture innovative talents.

Key words: Chemistry experiment teaching model, Autonomy, Creativity
