高速公路的修建,连结两地的公路明明可以修筑成直线段,但技术员却总是要有意地设计几处弯道。原来据心理学的研究,司机驾车长时间行驶在平直的道路上时,视觉容易疲劳,心理容易麻痹,注意力容易分散,也就容易发生事故。一定数量的弯道,则可以有效地克服这种现象使司机一直处于警醒戒备状态,以保证行车的安全。数学教学过程中的“弯道”表现于教师的故意出错或设计陷阱,诱使学生失误出错,再利用这些契机实现多方面的教育目标,这就是被教育心理学所命名
The construction of the expressway, the road connecting the two places can obviously be built into a straight line, but the technician has always intentionally designed several corners. According to the original psychology of the study, the driver driving a long time driving in a straight road, the visual fatigue, psychological paralysis easily, attention easily dispersed, it is prone to accidents. A certain number of corners, you can effectively overcome this phenomenon so that drivers have been on alert alert, to ensure traffic safety. Mathematical teaching process “bend ” is manifested in the teacher's intentional mistakes or design pitfalls to induce students to make mistakes, and then use these opportunities to achieve a wide range of educational goals, which is named by the educational psychology
