引例(2012全国大纲卷理12)正方形ABCD的边长为1,点E在边AB上,点F在边BC上,AE=BF=3/7,动点P从E出发沿直线向F运动,每当碰到正方形的边时反弹,反弹时反射角等于入射角,当点P第一次碰到E时,P与正方形的边碰撞的次数为()A.16 B.14 C.12 D.10本题作为选择题压轴题出现,相对较难,能力要求较高,解题时需进行一些探索,从中发现规律后才可能正确解答.笔者从探究性学习的模式对此试题加以探讨开发利用,供参阅.1策略探究探究1从简单做起,归纳、猜想
For example, the side length of the square ABCD is 1, the point E is on the side AB, the point F is on the side BC, AE = BF = 3/7, and the moving point P moves from F to E in a straight line , Bounce each time the square edge bounces, the bounce angle is equal to the angle of incidence, when the first point P hit E, P and the square side of the collision number of () A.16 B.14 C.12 D.10 This question as a multiple choice questions finale appeared, relatively difficult, higher ability requirements, the problem-solving need to be some exploration, from which the law may be the correct answer.
