Research On The Development Of Data Collection And Management For Teacher Observation And Evaluation System

Along with the rapid development of the cause of education, teacher evaluationdata collection and management has become an important part of the education sector.This system has more in-depth study of data mining technology on the number ofreferences.There is an important data processing method in data mining, it is the rough settheory, rough and theory is a deal with fuzzy and uncertain knowledge of the newmathematical tools. Information goes through the rough and methods of treatment, inorder to gain valuable knowledge. This system is to draw on the basis of the results ofprevious studies, a new teacher evaluation method based on rough set theory.Through the use of the nature of the tolerance relationship, a new approach tocalculate the compatibility class, while the introduction of restrictions given a newtheorem of the nuclear properties of the generalized decision function and prove itscorrectness. As heuristic information, followed by property to the amount ofinformation given to attribute reduction in incomplete information system based onthe amount of information, this reduction method can reduce the computationalcomplexity to calculate the number of speed reduction also increased, by proved thatthe method is simple and effective. The final reduction method through the newprogram will draw simple rules, some reference for teacher evaluation.
