让学生自然解法中的不合理在同伴互助下顿悟,在教师引导下归真,使解题受挫者知错善学,这是我们日常教学中应努力践行的。中考复习时,笔者将苏科版《义务教育教科书·数学》九年级下册第5章“二次函数”复习参考题“探索研究板块”第11题改编成:如图1,在Rt△ABC中,∠ABC=90°,AB=6,BC=8,点P以1 cm/s的速度从点A沿AB向点B运动,同时点Q以
Let the students in the natural solution of the unreasonable peer-assisted under the epiphany, under the guidance of teachers Guizhen, frustrated problem-solving who know the wrong kind of learning, which is our daily teaching should strive to practice. Exam review, the author Su Ke version of “compulsory education textbooks · mathematics” ninth grade volume fifth chapter “quadratic function” review reference questions “to explore the research section” eleventh title into: as shown in Figure 1, In Rt △ ABC, ∠ABC = 90 °, AB = 6, BC = 8, point P moves from point A to point B at a rate of 1 cm / s, while point Q
