物理解题过程可分为四个相互联系的环节所构成,即审题→探索→表述→回顾。审题是解题的前提,是学生进入问题情景和启动思维的起点。审题的过程就是从题中获得信息的过程,而条件信息是必须首要获得的信息,能否获得清晰、准确的条件信息是决定解题成功与否的关键因素。本文通过对几道高考试题的剖析,谈谈物理审题中的条件分析。一、审隐含条件试题中的条件有的显而易见,有的隐藏不露,而且条件的隐含形式多样,审题时一定要从多角度、多方面、多层次地分析和挖掘。例1.(97年全国试题)质量为 M 的木块位于粗糙水平桌面上,若用大小为 F 的水平恒
The process of object comprehension can be divided into four interrelated links, namely, examining → exploring → representation → review. The examination question is the premise of problem solving, and is the starting point for students to enter the problem scene and start thinking. The process of question-questioning is the process of obtaining information from the question, and the conditional information is the information that must be obtained first. Whether clear and accurate conditional information can be obtained is a key factor in determining the success of the problem-solving. This article analyzes the conditions in the physical examination questions by analyzing several high exam questions. I. The conditions in the examination of hidden conditional problems are obvious, some are hidden, and the conditions are implied in various forms. The examination must be analyzed and excavated from multiple perspectives, in many aspects, and in multiple levels. Example 1. (97 national examination questions) Masses of mass M are located on a rough horizontal table, if horizontal constants of size F are used
