DEVELOPMENT OF CLASSIFICATION FOR CLOSED TEST TASKS

The expediency of inclusion in one test of various types of test tasks (TT's) that adequate to the content of the studied materials and to the purposes of testing in the best way is often marked. However, developers of tests in practice are often forced to be limited and to include in one test several tasks of only one or of two types (- with a choice of one or several answers). This restriction is usually caused both by opportunities of specialized software, and by absence of classification TT's according to their structures. The purpose of the present work was development of classification for closed forms of test tasks according to their structures. For the purpose the principle of the system analysis to the consideration ТT and for investigation of ТT's elements, of TT's elements properties, and of links between TT's elements was applied. Having chosen properties of TT‘s elements and some special kinds of links between TT's elements as criteria, a classification of TT's by structural types was developed and 6 structural types for closed forms of TT's were discovered. The presented work has allowed to determine and to describe invariant structure of the test task, and to make a classification of test tasks by structural types. We consider that the given classification of these TT's structures can form a basis for an estimation of complexity level of TT's made on the basis of the studied materials and will allow in the further to develop test tasks of several complexity levels for pupils of different categories. Developed classification can also serve as a reference point for creation of software intended for the control and estimation of pupils' knowledge.
