三怎样设计选择题 1.什么是“两面设计”?(正面设计和反面设计) 一个问题和这个问题的答案,在思考的顺序上,究竟谁先谁后,这对科研和教学来讲,情况是不同的。科研课题的设计中,答案在先,问题在后。例如问题:什么是梯形?设计者是先有答案,即梯形的定义,后有问题。即对梯形的定义发问.因此,教学习题的设计是从答案出发的,答案,既是问题的终点。也是问题的起点。从这个意义上讲,答案,既是问题的终点,也是问题的起点,从这个意义上讲,答案,是习题设计的中心。这里所说的答案,自然是正确答案,如“什么是梯形”这个问题的正确答案就是:一组对边平行,另一组对边不平行的四边形。对于普通题,设
III. How to design multiple choice questions 1. What is “two-sided design”? (front design and negative design) The answer to a question and this question, in the order of thinking, who is first and foremost, this is the case for scientific research and teaching. It is different. In the design of research projects, the answer is first and the problem is later. For example, the question: What is a trapezoid? The designer is the first answer, that is, the definition of the trapezoid, after the problem. That is, the definition of the trapezoid is asked. Therefore, the design of the teaching question is based on the answer and the answer is the end of the question. It is also the starting point of the problem. In this sense, the answer is both the end of the problem and the starting point of the problem. In this sense, the answer is the center of the problem design. The answer here is naturally the correct answer. The correct answer to the question “What is a trapezoid?” is: a set of quadrilaterals with parallel sides and nonparallel parallels with the other side. For normal questions, set
