Testing for general and inorganic chemistry in the MOODLE system

Abstract

The current epidemiological situation in the world forces the pedagogical community to switch to the use of various forms of education using distance educational technologies. One of the most difficult problems of organizing distance learning is the problem of various forms of monitoring students knowledge. The most promising area for assessing the quality of knowledge is computer testing. Based on many years of experience in the development of computer test tasks, the basic requirements for computer test tasks and for computer tests are formulated, which make it possible to increase the efficiency of their use to control students knowledge. Examples of the correct representation of answer options in tasks with a choice of answer options (in closed test tasks) are given and ways to reduce the probability of guessing the correct answer are considered. With regard to the course "General and Inorganic Chemistry", the features of the use of various forms of test tasks are analyzed using specific examples. For the organization of computer testing of first-year bachelor degree students in the course "General and Inorganic Chemistry" the Moodle system was chosen. This system has various functions for creating tests, as well as for conducting training and control testing. For the convenience of entering test tasks into the Moodle system, these tasks must be converted into GIFT format. After that, GIFT tasks are easily imported into Moodle. Examples of different forms of test items in WORD and GIFT formats are given. The Moodle distance learning system (platform) has introduced a bank of tests for the course "General and Inorganic Chemistry", which is taught to first-year bachelor degree students of the Mendeleev University of Chemical Technology of Russia. The features of using this platform for organizing computer testing when using distance and blended forms of education are shown.
