杂化轨道理论是解释物质分子组成及其空间结构的基础理论,其内容特点是“知识抽象,理论性强”.课标要求学生能掌握杂化轨道理论、价层电子对互斥理论及判断简单分子或离子的空间构型的综合运用.该内容既是学生学习的难点,也是教师教学的难点,在课程实施过程中,采用有效的教学手段显得尤为重要.利用Flash技术将杂化过程制作成动画形式的课件,有利于学生生成直观、形象的知识概念,创设的教学情景也能
Hybrid orbital theory is to explain the composition of matter and its spatial structure of the basic theory, its content is characterized by “knowledge abstraction, strong theory.” The standard requires students to master hybrid orbital theory, the valence electron mutual exclusion theory And to determine the comprehensive use of the spatial configuration of simple molecules or ions.The content is not only a difficult point for students to learn but also a difficult point for teachers to teach.It is very important to adopt effective teaching methods in the process of curriculum implementation.Using Flash technology to hybridize the process Produced as animated forms of courseware, is conducive to students to generate intuitive, image of the concept of knowledge, the creation of teaching scenarios can
