“电解质”是人教版必修1第二章“化学物质及其变化”第二节的教学内容。本课题属于概念原理知识的教学。从教材的体系看,电解质、非电解质是初中学习溶液导电性、酸碱盐电离知识的延续和深化,又是学习电解质溶液理论知识的基础,在教材中具有承上启下的作用。通过这节课的学习,建立电离的概念,引导学生从微观离子角度认识水溶液中的电解质,发展了学生的微粒观,帮助学生形成用微观实质解释宏观现象的化学思想。 “Electrolyte ” is the teaching content of the second chapter of “PEP 1 compulsory 1 Chemical substances and their changes”. The subject belongs to the concept of the principle of knowledge teaching. From the teaching material system, electrolytes and non-electrolytes are the continuation and deepening of knowledge of junior high school learning solution conductivity and acid-base salt ionization, and are also the basis for learning the theoretical knowledge of electrolyte solution. Through the study of this lesson, the concept of ionization was established to guide students to understand the electrolyte in aqueous solution from the perspective of micro-ion, to develop the concept of students’ particles and to help students to form a chemistry idea that uses macroscopic interpretation of macroscopic phenomena.
