Assessment methods and criteria: Assessment of knowledge is provided by current and examination controls.
Current control:
– preparation and implementation of practical classes;
- preparation, execution and protection of laboratory works.
Examination control is carried out during the examination session in written and oral form.
Current monitoring of practical and laboratory classes is carried out in order to identify the student's readiness for classes in the following forms:
• a selective oral survey before the start of classes;
• frontal verification of the performance of preliminary laboratory work;
• evaluation of the student's activity in the course of classes, submitted proposals, original solutions, clarifications and definitions, additions to previous answers, etc.
Критерії оцінювання результатів навчання: - current control (20 points): oral survey; written reports on laboratory work;
- final control (80 points): the examination test is valued at 70 points, the oral component - 10 points.
Порядок та критерії виставляння балів та оцінок: Points for current and exam control are assigned as a percentage of the maximum grade for the educational material of the component based on the following criteria for evaluating the student's knowledge and skills:
100–88% – awarded for a high level of knowledge;
87–80% – awarded for knowledge of the educational material of the component above the average level, including calculations, reasoned answers to the questions asked (a small amount of inaccuracies is possible);
79–71% – a generally correct understanding of the educational material of the component is presented, including calculations, reasoned answers to the questions, which, however, contain certain (insignificant) shortcomings;
70–61% – awarded for mediocre knowledge of the educational material of the component;
60–50% – awarded for weak knowledge of the educational material of the component;
49–26% – presented for ignorance of a significant part of the educational material of the component;
25–00% – awarded for not knowing a significant part of the educational material of the component.
Current and control testing is carried out in the National Security Service and the grade is automatically assigned for all test tasks.
The exam is conducted in written and oral form (the exam test is valued at 70 points, the oral component - 10 points).
The oral examination involves a sample question from different sections of the course and the completion of simple tasks.
