化学是一门以实验为基础的学科,化学实验在整个化学课堂教学中有着不可代替的作用。然而,当下的高中化学实验教学实际存在很多无效现象。笔者认为,提高高中化学实验教学有效性,教师充分认识实验教学对培养学生能力的重要作用;用化学实验激发学生的求知欲望;重视实验教学的过程;做好演示实验;实现化学实验教学的转变;借助多媒体技术。
Chemistry is an experiment-based discipline. Chemistry experiments play an irreplaceable role in the entire chemistry classroom teaching. However, the current high school chemistry experiment teaching actually has many invalid phenomena. In my opinion, to improve the effectiveness of high school chemistry experiment teaching, teachers fully understand the important role of experimental teaching in cultivating students ’abilities; using chemistry experiment to stimulate students’ curiosity desire; paying attention to the process of experimental teaching; doing demonstration experiment; realizing the transformation of chemistry experiment teaching With multimedia technology.
