化学是九年级学生新增的一门学科,也是学生最为喜欢的课程。与其说是喜欢化学课程,倒不如说,他们喜欢千奇百怪的现象,变化多端的化学实验。对学生而言,不仅化学实验是形象的、具体的,而且相对于理科的枯燥,化学现象奇特且吸引人,可以动手操作,通过学生自己的观察、分析和动手,可以得到理论知识的升华,而且化学实验也是自由的、自主的,但有时会因为课堂组织的不完善,学生准备的不充分,而被“凑热闹”钻了空子,严重影响实际实验教学的效果和质量。如何上好一堂化学实验课,笔者认为应该注意以下几点:一、精心准备,做好课堂演示实验教师演示实验,不仅对于培养学生良好的实验习惯有着非常 Chemistry is a new addition to ninth graders and is also the student’s favorite course. Rather than like chemistry courses, Rather than say that they like all kinds of strange phenomena, varied chemistry experiments. For students, not only chemical experiments are vivid, concrete, but also relative to the dryness of science, chemical phenomena are peculiar and attractive, and can be hands-on operation. Through the students’ own observation, analysis and practice, the theoretical knowledge can be sublimated, And chemical experiments are free and autonomous, but sometimes because of imperfect classroom organization, inadequate preparation for students, and “get along” got the loophole, seriously affecting the effectiveness and quality of experimental teaching. How to take a good chemistry experiment class, I think we should pay attention to the following points: First, well prepared to do a good job in the classroom Experimental teacher demonstration experiment, not only for students to develop good experimental habits have a very
