Assessment methods and criteria: Diagnostics of students' knowledge based on the results of the discipline is carried out as follows.
1. Defense of the results of practical work and tests. It is conducted orally by questioning on the topic, methodology and main results obtained during the work.
2. Defense of the results of calculation and graphic work. It is conducted orally by questioning on the topic, methodology and main results obtained during the work. The maximum number of points is 20.
3. Credit control on the results of studying the discipline. The written component consists of three-level theoretical tasks and is conducted in test form in the Virtual Learning Environment. The oral component is based on the results of the written component for a more thorough assessment of knowledge
Критерії оцінювання результатів навчання: Current control.
The current score is formed on the basis of the defense of reports for practical, laboratory and calculation-graphic works in oral form by questioning theoretical material on the methodology and results of research. The maximum possible number of points for the current control is 30 points.
Credit control.
Semester control is realized by solving tasks of the third level.
Tasks of the first level of complexity (provide control of knowledge approximately on the verge of "unsatisfactory-satisfactory" and are evaluated by the same number of points: 3 points - correct answer, 0 points - incorrect answer. The maximum possible number of points in case of providing correct answers to all questions of the task of the first level of difficulty is 15 points.
The tasks of the second level of difficulty provide control of knowledge on the verge of "satisfactory-good" and are evaluated in the range of 0 ... 10 points, depending on the accuracy, conciseness and completeness of the question posed in the task. The maximum possible number of points in case of providing correct answers to all questions of the task of the second level of difficulty is 20 points.
The task of the third level of difficulty provides control of knowledge on the verge of "good-excellent" and is evaluated in the range of 0 ... 15 points, depending on the logic and sequence of solving the problem, completeness of explanation, providing the necessary diagrams and the ability to use reference literature. The maximum possible number of points for a correct answer is 15 points.
The maximum possible number of points for the semester control is 60 points.
Oral component
The oral component, which is assessed at 10 points, is introduced to provide students with the opportunity to supplement the answer to the controversial tasks of the semester control and improve their overall grade.
