课堂提问可以充分地激发学生的思维活动,使学生通过独立思考来获取知识;同时它又能活跃课堂气氛,集中学生的注意力,强化教学效果。但是课堂提问的效果与教师课前是否作精心的教学设计有密切关系。提问设计和提问时应注意以下几点: 一、忌问题的题意不明确课堂提问中,提出的每一个问题,都应该题意清楚,要求明确,使学生一听便知道准备回答什么,从哪些方面去思考推理判断。例如试比较S与Cl的性质并解释。这个问题是要求学生比较S和Cl的元素性质还是其单质性质?比较物理性质还是化学性质?是从原子结构上上解释还是从它们在元素周期表中所处的位置去解译?这种问题,学生难以回答。另外口头提问时,句子不宜过长,转弯抹角不宜过多,不必做文字游
