Birnbaum's models for the assessment of quality of dough «linear algebra, analytical geometry»

Quality of the "Linear Algebra, Analytical Geometry" test by means of the modern theory of testing is investigated, namely, two models of Birnbaum are under construction: two- parametrical and three-parametrical. The two-parametrical model unlike one-parametrical1 Lidia A. Muratova, Cand. of Tech. Sci., Associate Professor of Higher Mathematics and Applied Informatics Departmentmodel Russia contains the parameter characterizing the differentiating ability of a task. In three-parametrical model appears also the third parameter considering guessing of the correct answer. At this stage the analysis of the results received according to dough is made and according to recommendations the conclusion about use of these or those tasks is drawn. Further information functions of separate tasks and all dough are based. Thus is used that fact that the amount of information (received by means of this task) about the level of knowledge, in inverse proportion to a standard error of measurement of this level. The result on information function speaks about goodness of test tasks.
