查询词典 affirmative proposition

Even thought the students tell the illustration and the proposition correctly, only few of them know that merely one counter-example is needed to contradict the proposition. Most students are rather inclined to regard the counter-example as restrictions and exceptions just like Lakatos says when the number of counter-example is less and example more than contradict proposition of examples. As a result, they are less able to deny negative proposition.

结果发现即使拥有正确判断图例与命题间关系的学童，在面临同时有正反例图例时，只有极少数学生知道只要一个反例就可驳斥命题，大部分学生在反例较少而正例多时，会倾向如Lakatos所描述把反例视为题目的限制或是特例，而不与有较多正例支持的命题陈述来冲突，故较无法正确拒绝错误命题。

Physics concepts, theorems as well as principles are primary content of physics learning, those knowledge take on the forms by proposition . In chapter 3, the study revealed that physics proposition are mainly obtained by reasoning (inductive reasoning such as tallying method, differentiation method and covariant method, deductive reasoning such as negative expression of hypothetical inference, affirmative expression of hypothetical inference ).Then by the means of experiment, the different condition needed when applying those reasoning was explored.

由于定义性概念、定理和定律等命题知识是物理教学的主要内容，所以在第三章中首先通过研究，表明物理命题主要是运用推理策略获得的(归纳推理策略中的求同策略、差异策略和共变策略，演绎推理策略)；然后通过实验等方法研究使用策略需要的条件；最后依据前面的研究提出适合物理命题学习的任务分析方法。
