新课程标准对高中化学实验的要求越来越高,可化学实验课堂教学因为教师不重视、学校条件不具备,教学效果存在低效和无效性。教师在教学过程中,必须合理把实验分类,使演示实验和学生分组实验有机结合,课前充分准备,课上目标明确,课后认真总结,使实验课堂实现高效率。
The requirements of the new curriculum standard for high school chemistry experiments are getting higher and higher. However, the teaching of chemistry experiment is inefficient and ineffective because teachers do not attach importance to the conditions of the schools and the conditions of schools do not have them. Teachers in the teaching process must be reasonable classification of the experiment, the demonstration experiment and the students grouping experiment organically, fully prepared before the class, a clear goal, after class conscientiously sum up, so that the experimental classroom to achieve high efficiency.
