以一次初中物理课堂教学观摩活动为例,针对初中物理课堂教学中的实验探究活动,提出问题情境的创设应符合学生的认知规律,服务于课堂教学目标;围绕所创设的问题情境,应让学生自主设计问题解决的步骤,尽享问题解决的过程;问题解决的设计过程应科学、规范、完整,有利于探究得出正确的结论;适时发挥评价功能,促进问题高效、科学地解决.
Taking a middle school physics classroom teaching activity as an example, this paper proposes that the creation of a problem context should meet the students’ cognition rules and serve the goal of classroom teaching. In view of the problem situations created, we should make Students should independently design the steps to solve the problem and enjoy the process of problem solving. The design process of the problem solving should be scientific, standardized and complete, which is conducive to finding the correct conclusion. It should also give full play to the evaluation function to promote the efficient and scientific solution of the problem.
