让事例穿插在技工院校物理教学中

On the Infiltration of Examples into Physics Teaching in Technician Colleges

在技校物理教学中适当地穿插事例,并加之一些形体语言,不仅可以提高学生的注意力,而且可以降低对知识点的理解难度。本文分别举例说明了如何在重力做功及重力势能、超重与失重、力矩、惯性、动量定理、新温度概念的建立、分子运动论、转动惯量等知识点的教学中,形象地融入一些事例,增强物理课的教学效果。需要注意的是:融入的事例,应与所授的物理知识相匹配;难度也应和技校学生的专业和知识层次相适应,只有这样才能使技校物理教学受益。

To properly infiltrate examples into physics teaching combined with some body languages in technician colleges can not only improve students＇ attention, but also reduce the difficulty of understanding knowledge. This paper illustrates how to vividly infiltrate examples into the teaching of gravity acting and gravitational potential energy, overweight and weightlessness, moment of force, inertia, theorem of momentum, establishment of the new concept of temperature, kinetic theory of molecules, and moment of inertia, in order to enhance the teaching effect of physics course. The following issues should be noticed： the examples infiltrated into it should match the physics knowledge instructed;the difficulty of examples should adapt to the professional and knowledge level of technician college students. Only through the above can benefit physics teaching in technician colleges.
