A set of electronic graphic tasks on descriptive geometry adapted for automated assessment systems

The paper raises the problem of quality control of graphic training of technical university students using an automated assessment system. Despite wide access to digital educational resources, the acceptance and checking of drawings and calculation and graphic works in technical universities is still performed manually by teachers. The authors propose replacing the usual forms of graphic tasks on descriptive geometry with electronic metric and positional tasks of a new type. The result of solving such problems is expressed as a number or a short answer and can be compared with the standard using any standard testing system, for example, LMS Moodle. The work presents 20 examples of electronic practical tasks on descriptive geometry, the solution of which can be performed in any graphic editor, and the answer is checked using an automated assessment system. The set of electronic assessment tools developed by the authors contains more than 600 variants of graphic tasks and is designed to check theoretical knowledge and practical skills related to the content of the Descriptive Geometry and Computer Graphics course. The correctness of the tasks is checked automatically by means of the tools of the LMS Moodle electronic learning environment without the participation of the teacher. Pre-designed sets of control parameters, such as area, length, distance, volume, quantity, condition, and type are used for assessment. The system is successfully used for current monitoring of knowledge, skills and abilities of first-year students at the Siberian Transport University. The data from monitoring the learning outcomes indicate the effectiveness of the use of automated diagnostics of the level of development of students’ graphic skills.
