创设问题情境,激发学生探究的兴趣,培养探究能力,这是物理教师应具有的素质。科学发展史上,几乎每一次质的飞跃都从问题开始,可见问题是科学创新的起源,所以新课程标准大力提倡探究性学习,即问题解决式学习。探究性学习旨在培养学生分析问题、解决问题,以至发现、提出问题的能力,从而提高学生的科学探究能力。这就要求教师在教学中必须把学生要学习的内容巧妙地转化为问题情境。教师是教学过程中问题情境 The creation of a problem situation, to stimulate students interest in exploring and cultivating the ability to explore, this is the physical teachers should have the quality.
