专题精讲动手操作问题是指通过动手操作对某种现象获得感性认识,再利用数学知识进行思考、探索和解决的一类问题,这类问题通常以折叠、剪拼、操作探究等形式出现,具有较强的实践性,能够有效考查同学们的实践能力、创新能力和直觉思维能力、发散思维能力等综合素质.解答动手操作问题的关键是要学会自觉地运用数学知识去观察、分析、抽象、概括所给的实际问题,揭示其数学本质,并转化为我们所熟悉的数学问题.解答实践操作题的基本步骤为:从实例或实物出发,通过具体操作实验,发现其中可能存在的规律,提出问题,检验猜想.
Thematic explanation The problem of hands-on operation refers to a type of problem that is obtained through the hands-on operation of acquiring perceptual knowledge of certain phenomena and then using mathematical knowledge to think, explore and solve. Such problems usually occur in the form of folding, clipping, operation and inquiry, Has strong practicality, can effectively check the students' practical ability, innovative ability and intuition thinking ability, divergent thinking ability, etc. The key to answering practical problems is to learn to consciously use mathematical knowledge to observe, analyze, abstract , Summarizes the actual problems given, reveals its mathematical nature, and into the familiar mathematical problems.Practical practice questions to answer the basic steps: starting from the instance or in kind, through the specific operation of the experiment, found that there may exist laws, Ask questions and test conjectures.
