生活中有许多问题值得我们去探索、去发现,如果我们在学生的数学入门阶段就有意识培养他们的积极主动的探索精神,对他们的终身发展将是意义深远的。比如,在学习了比例的知识后,让学生测量校内旗杆的高度。每组开始了测量活动,两天后,做了详细汇报:第一种方法,我们用目测的方法测出旗杆的高度大约是12米;第二种方法,在一个阳光灿烂的早上,我们几个同学站立在旗杆旁先测出身高再测出影长发现影长与身高的 There are many questions in life that deserve our exploration, and find out that if we consciously cultivate their proactive exploration spirit in our students’ introductory maths, they will be of far-reaching significance to their lifelong development. For example, after learning the ratio of knowledge, let the students measure the height of school flagpoles. Each group began the measurement activities, two days later, made a detailed report: The first method, we use the visual method to measure the height of the flagpole is about 12 meters; The second method, in a sunny morning, a few of us Students standing next to the flagpole to measure the height and then found the shadow length and height
