Assessment methods and criteria: Students' knowledge is assessed using the following methods: 1. Defense of reports for laboratory works in oral form by surveying the theoretical material on the topic of the work and research methodology. 2. Current express control by means of a virtual educational environment or oral survey, tests, practical works, assessment of activity and submitted proposals. 3. Conducting a written exam based on the results of studying the discipline, which consists of tasks of various levels of difficulty. 4. Conducting the oral component based on the results of the written exam.
