Assessment methods and criteria: Assessment of students' knowledge in the discipline "Design of ventilation systems" is carried out in the form of current controls, and semester control of knowledge, which is carried out at the end of the semester. Current control of students' knowledge of the discipline "Design of ventilation systems" includes the following forms of assessment: Assessment during practical work: - Survey or testing of students' knowledge of theoretical material - 0.5 points for each lesson during the semester (8 lessons). Assessment during laboratory work: - Score for performance and defense of laboratory work - 3.0 points for each. Assessment of independent (in particular, individual) work: - Evaluation of the completed individual course project - 20 points. Points are awarded for the correct performance of individual course work and its defense. Semester control of knowledge includes the results of the current control of students' knowledge, which was conducted during the semester, and examination control. Exam tasks are also built on three levels of difficulty. The maximum amount of points for the exam task is 60. The results of the current control (maximum - 40 points) are added to this number. The maximum number of points for the semester control is 100. The actual number of points received by the student is transferred to the state final grade.
