在解析几何的教学过程中,思维定势起着重要作用.在笔者的教学中,很多学生一遇到解析几何中的运算问题:死算,最后一定能够得到我们所要的答案.这就是思维定势,思维定势影响着问题的解决.笔者从教学中举出两个例子,说明思维定势在解析几何运算中的正迁移和负迁移.例1已知椭圆的中心是原点O,焦点在x轴上,短轴的端 In the teaching of analytic geometry, mindset plays an important role in the teaching of the author, many students encounter analytic geometry problems: dead end, and finally be able to get the answer we want .This is thinking Potential, thinking set the situation affects the solution of the problem.The author gives two examples from teaching, thinking that the trend of thinking in the analytical geometry of the positive and negative migration migration.Example 1 known elliptical center is the origin O, the focus is on x-axis, short axis of the end
