在课堂教学中,常常会出现教师事先难以精确预料的问题情景与偶发事件,经常会有与课前预设不一致甚至相矛盾的意外情况发生。面对如此之多的有价值的动态生成性资源,独具慧眼的教师会善于捕捉并及时纳入于临场设计之中,巧妙运用于教学活动之中,使课堂流光溢彩。 In classroom teaching, teachers often appear difficult to accurately predict the situation in advance and accidental events, often with pre-class inconsistent or even contradictory accidents occur. In the face of so many valuable and dynamically generated resources, discerning teachers are adept at catching and integrating timely on-the-spot design, cleverly applied in teaching activities to make the classroom enjoyable.
