Assessment of the student's knowledge
Teacher oversees various tasks related to ongoing assessment and determines students' current performance twice during each academic period. Ratings 1 and 2 are formulated based on the outcomes of this ongoing assessment. The student's learning achievements are assessed using a 100-point scale, and the final grades P1 and P2 are calculated as the average of their ongoing performance evaluations. The teacher evaluates the student's work throughout the academic period in alignment with the assignment submission schedule for the discipline. The assessment system may incorporate a mix of written and oral, group and individual formats.

| Excellent | Good | Satisfactory | Unsatisfactory | |
| Review of lecture notes and individual oral interview | Demonstrates systemic theoretical knowledge, knows terminology, logically and consistently explains the essence of phenomena and processes, makes reasoned conclusions and generalizations, gives examples, shows fluency in monologue speech and the ability to quickly respond to clarifying questions | Demonstrates solid theoretical knowledge, knows terminology, logically and consistently explains the essence of phenomena and processes, makes reasoned conclusions and generalizations, gives examples, shows fluency in monologue speech, but at the same time makes minor mistakes that he corrects independently or with minor correction by the teacher | Demonstrates shallow theoretical knowledge, shows poorly formed skills in analyzing phenomena and processes, insufficient ability to draw reasoned conclusions and give examples, shows insufficient fluency in monologue speech, terminology, logic and consistency of presentation, makes mistakes that can only be corrected by a teacher. | Demonstrates systemic theoretical knowledge, knows terminology, logically and consistently explains the essence of phenomena and processes, makes reasoned conclusions and generalizations, gives examples, shows fluency in monologue speech and the ability to quickly respond to clarifying questions |
| Protection of practical tasks | Completed the practical work in full with the necessary sequence of actions; in response, correctly and accurately performs all records, tables, drawings, graphs, calculations, correctly performs error analysis. When answering questions, he correctly understands the essence of the question, gives an accurate definition and interpretation of the main concepts; accompanies the answer with new applications, is able to apply knowledge in a new situation; can establish a connection between the studied and previously studied material, as well as with the material acquired in the study of other disciplines | I fulfilled the requirements for the "5" rating, but 2-3 shortcomings were made. The student's answer to the questions meets the basic requirements for answering 5, but is given without applying knowledge in a new situation, without making connections with previously studied material and material learned from studying other disciplines; one mistake or no more than two shortcomings are made, the student can correct them independently or with a little help from a teacher | I have not completed the work completely, but at least 50% of the volume of practical work, which allows me to obtain correct results and conclusions; errors were made during the work. When answering the questions, the student correctly understands the essence of the question, but in the answer there are separate problems in mastering the questions of the course, which do not prevent further assimilation of the program material; no more than one gross error and two shortcomings were made | Completed the practical work in full with the necessary sequence of actions; in response, correctly and accurately performs all records, tables, drawings, graphs, calculations, correctly performs error analysis. When answering questions, he correctly understands the essence of the question, gives an accurate definition and interpretation of the main concepts; accompanies the answer with new applications, is able to apply knowledge in a new situation; can establish a connection between the studied and previously studied material, as well as with the material acquired in the study of other disciplines |
| Written work, defense | A complete and complete picture of the topic, including the history of the topic, leading scientists, modern vision, methods and techniques for preventing negative consequences | The origin and problems of the problem have not been fully disclosed. In general, complete knowledge is demonstrated, perhaps insufficiently systematized knowledge | Episodic, fragmentary knowledge, not systematized. | A complete and complete picture of the topic, including the history of the topic, leading scientists, modern vision, methods and techniques for preventing negative consequences |
| Milestone testing | Corresponds to the points for the answered questions (90-100) | Corresponds to the points for the answered questions (70-89) | Corresponds to the points for the answered questions (50-69) | Corresponds to the points for the answered questions (90-100) |
Evaluation form
The student's final grade in the course is calculated on a 100 point grading scale, it includes:
- 40% of the examination result;
- 60% of current control result.
The final grade is calculated by the formula:
| FG = 0,6 | MT1+MT2 | +0,4E |
| 2 |
Where Midterm 1, Midterm 2are digital equivalents of the grades of Midterm 1 and 2;
E is a digital equivalent of the exam grade.
Final alphabetical grade and its equivalent in points:
The letter grading system for students' academic achievements, corresponding to the numerical equivalent on a four-point scale:
| Alphabetical grade | Numerical value | Points (%) | Traditional grade |
|---|---|---|---|
| A | 4.0 | 95-100 | Excellent |
| A- | 3.67 | 90-94 | |
| B+ | 3.33 | 85-89 | Good |
| B | 3.0 | 80-84 | |
| B- | 2.67 | 75-79 | |
| C+ | 2.33 | 70-74 | |
| C | 2.0 | 65-69 | Satisfactory |
| C- | 1.67 | 60-64 | |
| D+ | 1.33 | 55-59 | |
