Assessment methods and criteria: In the process of current and semester controls, the following methods of monitoring the learning outcomes are used: oral survey; written survey; practical examination; standardized control. The frontal oral examination is carried out in laboratory classes. The individual oral examination takes place in laboratory classes as well as during the semester exam. The written survey is used when checking the independent work of students, calculation works, homework, and end semester exam. The practical test of the knowledge takes place during the performance of laboratory work, in the process of which the skills of working with devices, measuring, performing calculations, analyzing the obtained results, drawing conclusions, drawing up a report on the work performed are revealed. At the standardized control, a test technique with a choice of answers is used. Test tasks are used in the examination tickets and independent work of students.
