苏科版《数学》八年级上册“轴对称图形”内容呈现的最大特点是——在探索中不断地进行表达形式多样化的证明.课本安排了折纸、画图、猜想等多种活动,为同学们提供自主探索的空间,引导大家在“做”中感悟轴对称图形的数学本质,然后又通过图形运动法、综合法、分析法、反证法、类比法等探索得到一些结论.现结合课本中的具体例子一一阐述.一、图形运动法图形运动(平移、翻折、旋转)既是探索发现图形旋转的有效手段,也是证明图形性质的一种 Su Ke version of “Mathematics” on the eighth grade “axisymmetric graphics ” The most important feature of the content is - in the exploration of continuous demonstration of the diversity of forms of expression.The textbook arranged origami, drawing, conjecture and other activities, Provide students with the space to explore independently and lead us to comprehend the mathematical essence of axisymmetric graphics in “doing ”, and then get some conclusions through the exploration of graphical motion, synthesis, analytic, contradiction and analogy. Combined with the specific examples in the text one by one.First, graphics movement law graphics movement (translation, flipping, rotation) is both an effective means to explore the discovery of graphics rotation, but also to prove the nature of the graphics
