Assessment methods and criteria: Forms of control: 1. Current control in practical and laboratory classes is carried out in order to determine the readiness of students for classes in the following forms: - selective oral survey before the start of classes. - frontal standardized survey with tests lasting 5-10 minutes. - frontal check of homework completion. - Calling individual students to the board to solve problems independently, written answers to individual questions asked during the laboratory class. - assessment of student activity in the course of classes, proposals made, original solutions, clarifications and definitions, additions to previous answers, etc. 2. Examination control is carried out in order to determine the level of students' knowledge in the following forms: - a frontal standardized survey using tests posted in the VNS of Lviv Polytechnic, lasting 20 minutes. - written examination paper lasting 70 minutes. - oral examination 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. The oral examination involves the teacher asking questions (tasks), preparing students to answer and demonstrate their knowledge, correcting and self-controlling the answers given in the process, analyzing and evaluating them. Criteria for evaluating the learning outcomes of students: - work in practical classes - 15 points; - work in laboratory classes - 15 points; - examination control - 70 points (written component - 60 points, oral component - 10 points). Total for the discipline - 100 points
