化学是一门以实验为基础的学科.通过观察演示实验现象以及学生实验,能够让学生体验到学习的乐趣,激发学生学习的兴趣,同时,也能让学生对理论知识有更深刻的理解,并且对学生实事求是的科学态度的培养有着不可替代的作用.为了搞好实验教学,笔者在教学实践过程中进行了探讨和尝试,概括起来可以从如下方面进行实验教学.一、改变演示实验的主体提高教学效果
Chemistry is an experiment-based discipline. By observing and demonstrating experimental phenomena and student experiments, students can experience the joy of learning and stimulate their interest in learning. At the same time, they can also provide students with a deeper understanding of theoretical knowledge. It also plays an irreplaceable role in cultivating the students’ practical attitude towards science. In order to do a good job in experimental teaching, the author has explored and tried during the teaching practice. To sum up, it is possible to conduct experimental teaching from the following aspects. First, change the subject of the demonstration experiment. Improve teaching effectiveness
