化学是一门研究物质的组成、结构、性质及其变化规律的自然科学.在平时的化学教学中不仅要让学生掌握基本概念、基本原理,更应该让学生具备化学学科的各种能力,如动手操作能力,思维概括能力,实验推理能力,快速解题能力等.而快速解题能力是基于各种能力基础之上,是学生综合能力的体现.学生在理解基础知识的同时对化学解题有一个全面的掌 Chemistry is a natural science that studies the composition, structure, nature and variation of matter, and in normal chemistry teaching, students not only need to master the basic concepts and basic principles, but also have the ability to possess a variety of chemical disciplines such as Hands-on ability, thinking ability, experimental reasoning ability, rapid problem-solving ability, etc. The rapid problem-solving ability is based on a variety of abilities, is the embodiment of the comprehensive ability of students.Students understand the basics at the same time chemical problems Have a comprehensive hand
