有效教学是指教师遵循教学活动的客观规律,以尽量少的时间、精力和物力的投入,取得尽可能好的教学效果,从而实现特定的教学目标,满足社会和个人教育价值的需求。实践表明,有效的高效课堂必须具备三个要素:基于目标的问题;基于问题生成和问题解决的学生自己的活动;在解决问题和活动的过程中学生思维的发展。 Effective teaching refers to teachers follow the objective laws of teaching activities, with as little as possible time, energy and material inputs, to obtain the best possible teaching results, so as to achieve specific teaching goals and meet the social and personal educational needs. Practice shows that effective and efficient classroom must have three elements: the goal-based problem; based on the problem-solving and problem-solving students ’own activities; and the development of students’ thinking in solving problems and activities.
