众所周知,化学是一门以实验为基础的自然科学,通过化学实验,能够加深学生对化学概念与化学理论的理解,培养学生实事求是、严肃认真的科学态度,同时也能培养学生观察、归纳、分析问题和解决问题的能力。因此,化学实验教学是提高化学教学质量的有效途径。然而,传统的实验教学就是教师演示—学生操作,单调、低效, As we all know, chemistry is an experiment-based natural science, through chemical experiments, students can deepen their understanding of the concept of chemistry and chemistry, students develop realistic and serious scientific attitude, but also can train students to observe, summarize, analyze Problem and problem solving skills. Therefore, chemical experiment teaching is an effective way to improve the quality of chemistry teaching. However, the traditional experimental teaching is the teacher demonstration - student operation, monotonous, inefficient,
