摘要
针对离子键与共价键在教学中存在本质分离、联系割裂和忽视“证据推理”素养发展目标的问题,依据元素周期律中金属性和非金属性的递变规律进行推理,并寻找证据进行证实或证伪,以认清离子键与共价键的静电作用的成键本质和辩证统一的关系,发展学生证据推理的核心素养,提高学生的逻辑思维能力。
In view of the problems of the separation of the essence,the separation of the connection and the neglect of the development goal of“evidence reasoning”literacy in the teaching of ionic bond and covalent bond,by reasoning according to the changing law of metal and nonmetal in the periodic law of elements and searching for evidence to prove or falsify,we can recognize the bonding essence and dialectical unity of the electrostatic action of ionic bond and covalent bond,to develop the core quality of students’evidence reasoning,improve students’logical thinking ability.
