在新课教学中,最重要的一项内容就是如何引入物理概念,使学生全面理解概念的内涵与外延,并学会运用概念分析问题、解决问题。然而,物理概念的引入方法是否恰当,不仅会影响到学生对物理概念的理解和掌握,而且还会影响到能否激发学生的物理学习兴趣,调动他们学习物理的积极性和主动性。因此熟练并灵活运用物理概念的引入技巧在教学中就显得尤为重要。 In the new course teaching, the most important part is how to introduce the concept of physics so that students can fully understand the concept of connotation and extension, and learn to use concepts to analyze and solve problems. However, the proper introduction of physical concepts will not only affect students ’comprehension and mastery of the concept of physics, but also affect whether they can stimulate students’ interest in physics and mobilize their enthusiasm and initiative in studying physics. Therefore, the introduction of skilled and flexible use of physical concepts in teaching is particularly important.
