摘要： 在数智技术发展的背景下，针对无机化学混合式教学中存在的问题，初步探索了无机化学“数智化”教学改革策略。建设知识图谱，开设AI助教，将知识图谱与AI助教应用于无机化学教学中，构建AI赋能的无机化学教学模式。以“沉淀溶解平衡”的教学为例，说明知识图谱、AI助教在学生学习中智能导学、伴学的应用情况，以及在教师精准把握学情、优化教学策略中的作用。通过课后测和课程考核成绩证明这种AI赋能的教学能够提高学生的学习意愿。

Abstract: In the context of advancing digital intelligence technologies, this study preliminarily explores reform strategies for “digital intelligence” in the blended teaching of inorganic chemistry, aiming to address existing challenges. A knowledge graph was constructed, and an AI teaching assistant was implemented, both of which were integrated into the blended curriculum to develop an AI-enhanced teaching model for inorganic chemistry. Using “precipitation dissolution equilibrium” as a case study, we demonstrate how the knowledge graph and AI teaching assistant facilitate intelligent guidance and accompaniment in students’ learning. Additionally, we highlight the role of educators in accurately assessing student learning conditions and optimizing teaching strategies. Results from post-class assessments and course evaluations indicate that this AI-enhanced approach significantly improves students’ motivation to learn.
