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:
- selective oral survey before the start of classes;
- evaluation of the student's activity in the process of classes, submitted proposals, original solutions, clarifications and definitions, additions to previous answers, etcControl 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 control work.
