基于不协调决策信息系统的有效教学影响因素分析

Analysis of Factors of Effective Teaching Based on Inconsistent Decision Information Systems

有效教学理念的推广与实施是新课程改革的重点项目之一,然而在深入贯彻有效教学方针的过程中,教学效果不明显等问题不断凸显。首先根据粗糙集约简理论给出约简算法。其次在对有效教学影响因素进行实地调查研究的基础上,通过随机抽样得到有关有效教学影响因素分析表,并将其转化为决策信息系统。然后利用约简算法对有效教学影响因素实例进行分析,得到分布约简、最大分布约简、分配约简、下近似约简和上近似约简。最后对有效教学影响因素决策信息系统的约简结果进行解释,从而指导有效教学方案的制定,提高有效教学的效果。

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 a- bout factors of effective teaching was constructed based on investigations about factors of effective teaching and ran- domly 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, assign- ment 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.
