一、开放性问题的类型开放性问题是相对传统封闭性问题而言第一类:条件开放型,即问题条件不完备或满足结论的条件不唯一.例如:给定一个盛有适量水的量筒,请你再选用一个实验器材,测量一小块矿石的密度.学生可根据学过的物理原理增添不同的实验器材来解决上述问题.第二类:结论开放型,即在给定的条件下,结论不唯一.例如:边长为 a、密度为ρ的正方
First, the type of openness issues is a relatively open type of issues compared to traditional closed issues in the first category: conditional open type, that is, the problem conditions are not complete or meet the conclusion of the conditions are not unique. For example: given a suitable amount of water measuring cylinder , Please choose a laboratory equipment to measure the density of a small piece of ore. Students can add different experimental equipment to solve the above problems based on the physical principles learned. The second category: Conclusion open type, that is, under given conditions , The conclusion is not unique. For example: square with side length a and density ρ
