课堂教学效率可用如下公式表示:课堂教学效率=有效教学时间/实际教学时间×100%这表明,有效教学时间与实际教学时间之比值越大,教学效率越高;比值越小,教学效率
Classroom teaching efficiency can be expressed by the following formula: Classroom teaching efficiency = effective teaching time / actual teaching time × 100% This shows that the greater the ratio of effective teaching time to actual teaching time, the higher the teaching efficiency; the smaller the ratio, the efficiency of teaching
