有一位伟人曾说过,提出问题某种意义上比解决问题更重要.一切科学探究都始于问题.课堂教学中的设问,既是老师引出话题的一种形式,也是启发式教学的常用模式,更是探究式学习的一个重要环节.精到的课堂教学设问,可以起到引导课堂教学的方向.引起学生注意,启发学生思维和化解教学难点的作用.课堂提问的针对性、适时性、层次性和创造性,反映教师对教材的理解和对学生的了解,体现教师的知识素养和艺术修养.下面通过高中《物理》“简谐运动”课堂教学一节中的几个片段谈谈物理课堂设问的几点体会.一、设问应具有针对性学生学习物理概念时,由于对其外延内涵理解不清或者“前概念”干扰因素等,造成概念模糊,针对概念易模糊处设问,通过前后左右旁敲侧击,可以使概念在“锤炼”中变得清晰.
One great man once said that raising a question is more important than solving a problem in the sense that all scientific inquiry starts with the problem.Asking questions in the classroom is not only a form of the teacher’s topic but also a common mode of heuristic teaching , But also an important part of inquiry-based learning.Exquisite classroom teaching questions, can guide the direction of classroom teaching.Get attention to students to inspire students thinking and resolve the difficulty of teaching the role of the classroom questions targeted, timely , Level and creativity, reflecting the teacher’s understanding of the teaching materials and understanding of students, reflect the teachers’ knowledge and artistic accomplishment.Through the high school “Physics” “Simple harmonic motion ” class teaching several sections First, set the question should have targeted students to learn the concept of physics, due to its lack of understanding of the extension of the content or “preconception ” interference factors, resulting in the concept of ambiguity, the concept of easy Ambiguity ask, by around knocking on the side, you can make the concept of “temper ” become clear.
