Assessment methods and criteria: Current control during practical and 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;
• frontal verification of homework:
- calling individual students to the board for independent problem solving, written answers to individual questions and written problem solving;
- assessment of student activity in the process of classes, submitted proposals, original solutions, clarifications and definitions, additions to previous answers, etc.;
- surveys and reports during practical and laboratory classes;
- defense of laboratory work, evaluation of reports for laboratory work.
Examination control is carried out in order to determine the level of student knowledge acquisition in the following forms:
- frontal standardized survey using tests posted in the Lviv Polytechnic Information Center, for 20 minutes;
- written examination work for 90 minutes;
- oral survey to assess the level of knowledge acquisition and achievement of learning outcomes. It consists in finding out the level of knowledge of students through direct contact with them during a test interview. Oral survey involves the teacher posing questions (tasks), preparing students to answer and demonstrate their knowledge, self-control and correcting errors during the answer, analysis and evaluation of the answer.
Final control is carried out by summing up the results of current control and semester examination control.
