在初中化学的教学中,元素与化合物知识在教学中特别重要,元素与化合物贯穿整个知识框架,其他知识都是围绕它拓展。如何根据元素与化合物知识的特点进行教学,科学地组织和指导学生的学习活动,激法学生的学习主动性和能动性,培养和发展学生的学习能力,是非常重要的。如何进行该知识的教学,本人有以下几点认识。一、课堂设计合理课堂教学设计应以探究教学为主,体现探究、合作学习,把时间还给学生。在学习元素与化合物知识时,先由学生自行阅读和理解,教师引导,营造一种合作探究的气氛,通过探讨、引导,让学生由求知到理解,从宏观上认识物质。在学习二氧化碳和一氧化碳的知识时,让学生阅读教材,提
In junior high school chemistry teaching, element and compound knowledge is particularly important in teaching, elements and compounds throughout the knowledge framework, other knowledge is around it to expand. It is very important to teach according to the characteristics of element and compound knowledge, to organize and guide students’ learning activities scientifically, and to stimulate the initiative and initiative of students and to develop and develop their learning abilities. How to carry out the teaching of this knowledge, I have the following understanding. First, the class design is reasonable Teaching design should be based on inquiry teaching, reflecting exploration, cooperative learning, the time back to students. When learning the knowledge of elements and compounds, students should read and understand them first. Teachers should guide and create an atmosphere of cooperation and exploration. By exploring and guiding students to make knowledge and understanding, they should understand the matter macroscopically. In learning carbon dioxide and carbon monoxide knowledge, allow students to read teaching materials, mention
