传统无机化学实验课程“教师讲授+演示”后照方抓药的教学模式导致学生缺乏思考，无法达成本课程在大学化学学习中的基础性和专业性教学目标。“对分课堂+学生演示”的参与式教学方法旨在引领学生通过课前自主学习、课堂交流讨论，在师生、生生互动基础上形成个人实验方案，是凸显教师主导和学生主体性的教学模式，是以学会学习和提升自主学习能力为教学目标的教学变革，实践证明具有一定的变革价值。The teaching mode of traditional inorganic chemistry experiment course is based menu followed by teaching and demonstration, which leads the student lack of thinking and enable to achieve the teaching objectives in university chemistry study. The participatory teaching method of "PAD + demonstrations by students" aims to guide students through self-study before class, class discussion, based on the interaction between students and teachers form personal experiment scheme. This kind of teaching model highlights teacher's leading and student's subjectivity. The teaching reform aims at learning and improving the ability of autonomous learning.
