Teaching Reform Strategy for Inorganic Chemistry Theory——Taking Valence Shell Electron Pair Repulsion Theory as an Example
In college chemistry teaching,inorganic chemistry is an important professional course in the teaching of chemistry majors.This course is usually arranged to be studied in the first year,which is the basis for learning other chemistry courses.The application of valence shell electron pair repulsion theory is also the key content of inorganic chemistry,which introduces the spatial configuration of speculated molecules.The teaching reform strategy is an effective measure taken by teachers in order to improve the teaching quality and consider the basic elements organically under the guidance of a certain goal.This paper takes the important knowledge point valence layer electron pair repulsion theory in the chapter of molecular structure as an example,and uses the knowledge students have mastered and the internal connection between the number of central atoms and lone electrons to guide students to better understand the knowledge point and learn to calculate and judge the spatial arrangement types of molecules,stimulate students'interest in learning chemistry,and at the same time,conduct moral thinking,thereby enhancing the quality of the course,to improve the teaching design of valence shell electron pair repulsion theory and thereby enhance the effectiveness of classroom teaching.
