Abstract: To popularize and apply the idea of effective teaching is one of important projects about curricular reform.However,many problems such as unremarkable teaching effect occur in the process of effective teaching.According to the theory of attribute reduction in rough set,an algorithm was firstly obtained for attribute reduction.Then a table about factors of effective teaching was constructed based on investigations about factors of effective teaching and randomly sampling,and transformed into a decision information system.Using the attribute reduction algorithm,the factors about effective teaching were also analyzed in order to obtain distribution reducts,maximum distribution reducts,assignment reducts,lower approximate reducts and upper approximate reducts attribute reducts.Finally the results of attribute reduction and attribu-te analysis were explained to guide the plan of effective teaching and further to improve teaching effect.

Key words: Rough set,Effective teaching,Attribute reduction,Inconsistent decision information systems
