Assessment methods and criteria: Interviewing and admission to laboratory work; Defense of laboratory work; Testing; Performance of laboratory work on individual tasks;
Критерії оцінювання результатів навчання: The task of the current control is a systematic check of understanding and assimilation of the program material, performance of laboratory work, skills to independently work on writing a report, abstract, ability to publicly, in writing or in electronic format present certain material. Preparation, performance and defense of reports on laboratory work are assessed by 1-2 points for group laboratory work and 2-4 points for work performed on an individual task. The task of the final examination control is a final check of the depth of the student's assimilation of the program material of the discipline, logic and relationships between its individual sections, the ability to creatively use the acquired knowledge; the ability to form one's attitude to a certain professional problem arising from the content of the educational component, etc. The assessment of oral and written test tasks of examination control depends on the form of the test task: 4. the correct answer to closed test tasks of the first level of complexity with one correct answer is estimated at 2...4 points, the incorrect answer is estimated at 0 points. There can be no intermediate assessment for these tasks; 5. correct answers to closed test tasks of the second and third levels of complexity with a choice of several correct answers, to establish correspondence, nested answers, missing words and the correct sequence, which, depending on the complexity, are estimated at 4...10 points. The criteria for assessing answers and completing tasks are: • completeness of the disclosure of the question; • integrity, systematicity and reasoning; • logic of presentation, speech culture; • analytical reasoning, ability to make comparisons, conclusions; • accuracy of the written work. The assessment of the student's learning outcomes is carried out according to a 100-point scale.
