乙醇与金属钠反应，是学生必须掌握的乙醇的重要化学性质之一，我们对乙醇的实验教学方法进行了一些探索，改进了实验方法，使实验教学达到了预期的效果．下面介绍我们的做法：一．我们设计的本实验的教学方法：１．将演示实验改为边讲边做的学生实验；２．教师演示实验仪器改?
The reaction of ethanol with metallic sodium is one of the important chemical properties of ethanol that students must master. We have conducted some explorations of experimental teaching methods for ethanol, improved experimental methods, and achieved experimental teaching. Here are our practices: 1. The teaching method we designed for this experiment: 1. Change the demonstration experiment to a student experiment done while speaking; 2. Teachers demonstrate the change of experimental instruments?
