欧拉图解在逻辑学教学中运用十分广泛,其目的是使抽象晦涩的逻辑推理变得更具体、更清晰、更形象,以易于学生理解和掌握.欧拉图解遵循一定的判定依据、步骤和注意事项,在三段推理教学中,它可以加深学生对三段论公理的全面理解和对三段论规则的灵活运用.但该方法也存在着画图时间冗长、画图过程繁琐、缺乏简明性等缺点,需通过建立“案例主导”教学模式,精心设计课前预习,综合运用多媒体资源等方式手段弥补不足.“,”Euler diagram is widely used in logic teaching. Its purpose is to make the abstract and obscure logical reasoning more specific, clearer and more vivid, so as to be easy for students to understand and master. Euler diagram follows certain judgment basis, steps and precautions. In the teaching of syllogism reasoning, it can deepen students\'\' comprehensive understanding of syllogism axioms and flexible application of syllogism rules. However, this method also has some disadvantages, such as long drawing time, cumbersome drawing process and lack of simplicity. It needs to make up for the deficiency by establishing a “case led” teaching mode, carefully designing preclass preview, and comprehensively using multimedia resources.
