Assessment methods and criteria: In the process of current and semester control, the following methods are used to monitor the learning outcomes of students: oral examination; written examination; practical test; standardized control. Frontal oral questioning is carried out in laboratory classes. Individual oral questioning takes place during laboratory classes and during the semester exam. Written questioning is used to check the independent work of students, calculations, homework, and semester exams. Practical testing of students' knowledge takes place during laboratory work, which reveals the formation of the ability to work with instruments, make measurements, perform calculations, analyze the results, draw conclusions, and prepare a report on the work performed. The standardized control uses a multiple-choice test methodology. Test tasks are used in examination tickets and in controlling the independent work of students.
