Assessment methods and criteria: - current control (40%) oral questioning, independent written work (40%); - final control (control measure - exam): Written, oral form (60%).
Критерії оцінювання результатів навчання: Current control (PC): Laboratory practice - 30 p Examination control (EC): written component - 60 p oral component - 10 points Together for the discipline (PC+EC) - 100 points Current control of students' knowledge In the process of current control, the memorization and understanding of the program material, the acquisition of the skills and abilities of specific calculations and justifications, elaboration, public and written presentation of certain issues of the discipline are checked. The objects of the current control of the student's knowledge are: - performance of laboratory work; - protection of laboratory work. Evaluation criteria for the performance of the test control task Each of the two levels of the control task is evaluated in a different number of points. At the first level, there are 8 test tasks with 3 answer options. It is evaluated in 0 or 5 test points: 5 points for a correctly established correspondence; 0 points if no correct match is found or no answer is given. At the second level, there are 2 tasks with a definition. The task of the second level is evaluated in 10 test points. A task with an incomplete formulation is evaluated in 0 or 9 test points: 10 points if the correct answer is indicated; 0 points if an incorrect answer is given or no answer is given. Points are withdrawn: a) for mechanical errors, lack of measurement units: 1 point; b) for insignificant small errors - up to 2 points; c) for fundamental errors - up to 50% of the points provided for the evaluation of the task; d) an answer not in accordance with the content of the task is assessed at 0 points. Thus, a test task performed correctly and in its entirety enables a student to receive 60 points. Oral component In the process of the oral component, the memorization and understanding of the program material, the acquisition of the skills and abilities of specific calculations and justifications, elaboration, public presentation of certain issues of the discipline are checked. For competent and complete answers during the oral component, the student will receive 10 points.
Порядок та критерії виставляння балів та оцінок: 100–88 points – (“excellent”) is awarded for a high level of knowledge (some inaccuracies are allowed) of the educational material of the component contained in the main and additional recommended literary sources, the ability to analyze the phenomena being studied in their interrelationship and development, clearly, succinctly, logically, consistently answer the questions, the ability to apply theoretical provisions when solving practical problems; 87–71 points – (“good”) is awarded for a generally correct understanding of the educational material of the component, including calculations, reasoned answers to the questions posed, which, however, contain certain (insignificant) shortcomings, for the ability to apply theoretical provisions when solving practical tasks; 70 – 50 points – (“satisfactory”) awarded for weak knowledge of the component’s educational material, inaccurate or poorly reasoned answers, with a violation of the sequence of presentation, for weak application of theoretical provisions when solving practical problems; 49-26 points - ("not certified" with the possibility of retaking the semester control) is awarded for ignorance of a significant part of the educational material of the component, significant errors in answering questions, inability to apply theoretical provisions when solving practical problems; 25-00 points - ("unsatisfactory" with mandatory re-study) is awarded for ignorance of a significant part of the educational material of the component, significant errors in answering questions, inability to navigate when solving practical problems, ignorance of the main fundamental provisions.
