Automatic Parameterized Generation of Test

The contribution deals with a proposal and implementation of a test generator from the prepared tasks of varied topics. The structure of questions in the individual tests can be controlled by input parameters which are described in the proposal. Then a simple format of an introductory bank of tasks containing, among others, also basic elements of the mathematical typesetting is proposed and described. Control information is also part of the input data which is complemented by parameters for each question influencing its listing in the generated tests. Together with the proposed modular architecture of the generator basic objects of its construction are described on the basis of the principles of the object-oriented programming and of the application of polymorphism by which flexible functionality of the generator is ensured. In the following part the process of solving a combination of the test questions according to the set parameters by means of the methods called depth-first search of tree and backtracking is illustrated. In the end the possibilities of choice of various output formats of the generated tests and the functionality of comparing the congruence of tests and the choice of the best test combinations are shown. The generator outputs are represented by an example of tasks generated in the required format, by a final matrix of the comparison of the congruence of the generated tests and by a proposal of a suitable combination of tests with regard to the requirement of minimizing the congruence between different test groups.
