Abstract

Abstract:

Instrumental analysis laboratory is one of the important courses in chemistry and related profession. Combining with the course characteristic and training objective, comparative teaching method has been brought into the classroom teaching. The meaning and function of the comparative teaching method have been pointed out. The practice and application of comparing in laboratory teaching have been introduced. The method has enhanced students' knowledge to all kinds of instruments functions and the features stimulated students' interest in experiment and the innovation spirit. Their cognitive abilities have been continuously built, enriched, improved and developed in the process of comparing. Good teaching results have been achieved.

Key words: Instrumental analysis, Comparative teaching method, Laboratory teaching
