化学是一门以实验为基础的学科,实验教学具有丰富的探究性功能,可以激发学生学习化学的兴趣,帮助学生形成化学概念,获得化学知识和实验技能,培养观察和实验能力,还有助于培养实事求是、严肃认真的科学态度和科学的学习方法.目前中学化学实验教学的“无效教学”和“低效教学”现状与新课程标准的要求格格不入,所以加强中学化学实验课的有效、高效的课堂教学已迫在眉睫. Chemistry is an experiment-based discipline. Experimental teaching is rich in exploratory functions that stimulate students’ interest in learning chemistry, help students to form chemical concepts, gain knowledge of chemistry and experimental skills, develop observation and experimental skills, and help At present, the status quo of “invalid teaching” and “inefficient teaching” in chemistry experiment teaching in high schools is incompatible with the requirements of the new curriculum standards, so strengthening the chemistry experiment class in middle schools The effective and efficient classroom teaching is imminent.
