教学的“有效性”是指,在教学活动中,教师采用各种方法和手段,用最少的时间、最小的精力投入,取得尽可能多的教学效果,实现特定的教学目标,满足社会和个人的教育价值需求而组织实施的活动。具体而言,教学的有效性包括三种含义,即有效果、有效率、有效益。这与“向课堂40分钟要效率”有相通之处,不过它的范围似乎更宽泛。 Teaching “validity ” refers to the teaching activities, teachers use various methods and means, with the least amount of time and effort, as much as possible to achieve the teaching effect, to achieve specific teaching goals, to meet the community And the educational needs of individuals and organize the implementation of activities. Specifically, the effectiveness of teaching includes three meanings: effective, efficient and effective. This is in line with the 40-minute efficiency in the classroom, though its scope seems broader.
