Application Mixed Diagnostic Tests in Blended Education and Training

Abstract

Relevance of computer based learning and testing of students are discussed. Construction of mixed diagnostic tests that are a compromise between unconditional and conditional components is used in order to develop blended education and training. It is proposed for control, monitoring students' knowledge, professional and personal skills and abilities, and designing learning trajectory of courses for every student. We suggest a technique for construction of optimal mixed diagnostic tests that is based only on the experts' knowledge about problem area. KEY WORDS Intelligent pattern recognition, tree of mixed diagnostic tests, learning trajectory, blended education and training.

Mixed diagnostic tests structure for learning and testing systems

“…We demonstrated that utilizing the mixed diagnostic tests in blended education and training for assessing knowledge, professional and personal skills and abilities. The proposed approach for developing the MDT uses methods of fuzzy and threshold logic [11].…”

“…The approach uses pattern recognition methods. An implementation of the MDT in intelligent learning and training systems was presented [11].…”

“…The main concepts used in our paper are the following [11]: Respondent (a person/student participating in a testing process). Diagnostic test (a test, providing to define the level of the respondent's knowledge and skills in comparison with a predetermined level).…”

“…The score is compared with threshold value pu, after which there is an appeal to any other unconditional test component determined on the MDT tree, moves to the conditional component of the test, or to the recommendations to return back for learning the corresponding topic [11]. The above step is based on methods of fuzzy and threshold logic.…”

“…Today it is one of the popular and useful means of learning assessment. A number of innovative assessment technologies were developed on the base of the MDT [11,12].…”
