有一次上数学课,老师讲到关键处,孩子们学的正投入。忽然,教室窗外传来了鼓号声,孩子们循声望去。原来是学校的鼓号队、花束队为了完成宣传任务在临时彩排呢。孩子们不时地望望窗外,一副心不在焉的样子。数学老师拍拍黑板,叫学生们把注意力收回来,学生们虽然表面上把眼睛转回了黑板,但是老师能看出来,学生的心没有回来。数学老师正要发脾气,忽然心生一计,笑呵呵地对学生说:“我们学校的鼓乐队很有气魄,花束队绚丽无比,这样吧,转过头我们一起欣赏三分钟,好好过过瘾。”听了老师的话,孩子们开始有点怀疑,确信后看了不到两分钟就全都坐好等着老师上课了。结果虽然外面有伴奏,孩子们的注意力并没有受多少影响。 请结合材料分析张老师处理此事的方法,谈谈你对课堂意外情况的认识和处理方法。
