有效性是课堂教学的生命。有效教学可以最大限度达到教育教学目的和教学效果。提高课堂教学的有效性是每一个教师都应该加以思考、探究的问题。如果学生不想学或者学了之后没有收获,即使教师教得再辛苦,也是无效教学。同样如果学生学得很辛苦,但没有得到应有的发展,也是无效或低效教学。 Effectiveness is the life of classroom teaching. Effective teaching can maximize education and teaching purposes and teaching effectiveness. Improving the effectiveness of classroom teaching is an issue that every teacher should think and explore. If the students do not want to learn or did not learn after learning, even if the teacher taught hard, it is invalid teaching. Similarly, if students learn very hard, but did not get due development, but also ineffective or inefficient teaching.
