当前,在课改新理念下成长一代的学生,思维活跃,充满着对知识的渴望,头脑中蕴藏着无限的智慧和潜力,往往在课堂上生成一些教师想不到的“问题”.本文记录一堂习题课,让我们看到了学生的聪明才智.题目已知:如图1,梯形ABCD中,AB∥CD,以AD为边作平行四边形ACED,DC的延长线交BE于点F.求证:EF=FB.
At present, the students who have grown up under the new idea of curriculum reform have active thinking and are full of the desire for knowledge. The mind contains infinite wisdom and potential, often generating some “problems” that the teacher can not think of in the classroom. The subject is known: As shown in Figure 1, trapezoidal ABCD, AB // CD, with AD as the side of the parallelogram ACED, DC extension of the line to pay BE at point F. Verify: EF = FB.
