Assessment methods and criteria: Current monitoring of laboratory classes is carried out in order to identify the student's readiness for classes in the following forms: - a selective oral survey before the start of classes; - assessment of the student's activity in the course of classes, submitted proposals, original solutions, clarifications and definitions, additions to previous answers, etc. Control questions are divided into: a) test tasks - choose the correct answers; b) problematic – creation of problematic situations; c) questions-replies - to identify cause-and-effect relationships; d) situational tasks - to determine the answer according to a certain situation; e) issues of a reproductive nature - determination of practical significance. The final control is carried out based on the results of the current control and performance of the examination work.
