随着新课程的实施,在物理教学过程中,探究成为物理课堂教学的主要方式,在探究活动过程中,归纳总结得出结论是很重要的一环.探究结果是探究活动的成果,如何有效直观地呈现出来,关系到整个探究活动的成败.探究结果的呈现要求准确、简洁、真实、直观、便于记忆和表达,通常有以下几种表达方式:语言表达这是在初中物理探究结果表达方式中使用最为广泛的一种.它一般适用于定性描述物理特性或物理规律,通常是用控制变量法、比较法进行研究,最后归纳并用语言描述.如导体电阻的大小与导体的材料、长度、横截面积以及温度有关;二力平衡的条件:作用在同一物体上的两个力大小相等、方向相反,并且作用在同一条直线上(同体、等值、反向、共线)等等.它要求归纳者具有一定的逻辑思维、推理、归纳总结和简洁、准确的语言表达能力.
With the implementation of the new curriculum, in the process of physics teaching, to explore the main way to become a physical classroom teaching, and to conclude and conclude is a very important part in the process of inquiry activities. The result of the inquiry is the result of the inquiry activity and how effective Intuitively, it is related to the success or failure of the whole inquiry activity.The presentation of the inquiry results requires accurate, concise, authentic, intuitive and easy to remember and express, and usually has the following expressions: Language Expression This is the expression of the result of inquiry in junior middle school physics It is generally used in the qualitative description of physical properties or physical laws, usually controlled variable method, comparative method to study, and finally summarized and described in language such as the size of the conductor resistance and the conductor material, length, Cross-sectional area and temperature; the conditions of the balance of the two forces: the two forces acting on the same object are equal in size and opposite in direction, and act on the same straight line (same body, equivalent, reverse, collinear) and so on. It requires the inducer to have a certain degree of logical thinking, reasoning, summarizing and concise, accurate language skills.
