该课通过物质分离与提纯、溶液配制、污水处理等一系列学科核心活动,实现离子反应核心概念在促进学生认识发展方面的功能与价值,丰富和发展学生认识电解质溶液的角度,如宏观的物质种类、物质现象,微观的微粒种类、相互作用以及微粒的数量,使学生在面对水溶液问题时,能够形成并固化下来一套明确的、宏观微观相结合、定性定量相结合的分析思路。 Through a series of disciplinary core activities such as material separation and purification, solution preparation and sewage treatment, this course realizes the function and value of the core concept of ion reaction in promoting students ’understanding of development, enriching and developing students’ understanding of electrolyte solution, such as macroscopic substance Species, physical phenomena, the type of micro-particles, the interaction and the number of particles so that students in the face of aqueous solution, the formation and curing of a set of clear, macro-micro combination of qualitative and quantitative analysis of ideas.
