化学是一门以实验为基础的自然科学,化学实验是化学教学不可分割的一个重要组成部分,培养学生的实验能力,是化学教学的目的之一,而化学实验教学的一个重要目的,就是使学生运用实验的方法去验证和探索物质的性质和变化规律。演示实验是化学教学中常用的直观教学手段,它能使学生加深记忆,便于学生理解和掌握。教学中,教师抓好演示实验教学,提高实验课教学效果,现就本人的经验与各位交流。
Chemistry is a natural science based on experiments. Chemistry experiment is an integral part of chemistry teaching. Cultivating students’ experimental ability is one of the purposes of chemistry teaching. An important purpose of chemistry experiment teaching is to make Students use experimental methods to verify and explore the nature of substances and the laws of change. Demonstration experiment is an intuitive teaching method commonly used in chemistry teaching. It can deepen students’ memory and make them easier for students to understand and master. In teaching, teachers do a good job of demonstrating experimental teaching and improve the effectiveness of experimental teaching. Now we share our experience with you.
