Increase in efficiency of process of testing of students on the basis of methods of excess coding and the filtration

One of the responsible moments in educational process - assessment of knowledge of the student. Today it most often conducting testing. At the same time, it should be noted that the student is an active element of a training system and, as a rule, aims in implementation process system of function of control. These purposes can not match the purpose of system (teacher). In the course of testing there is no direct contact with the teacher. What leads to errors of assessment of knowledge. It is offered to consider in case of a process improvement of testing it as system of information transfer in the channel with noise and to consider “activity” of two-level system the student - the teacher. Consideration of the learning system as a two-level active information system allows us to describe the testing process using a channel matrix and propose the same methods for combating noise of testing that are used in information systems to isolate the “right” signal from noisy: excessive coding and filtering.
