Cycle: Base disciplines
Goal
- Acquaintance with modern ways of protecting building structures from corrosion, the rules of corrosion wear in the verification calculations, the rational design of elements and assemblies.
Objective
- Study the general principles of protection of building structures of industrial buildings and structures against corrosion.
Learning outcome: knowledge and understanding
- Ability to classify the environment by the degree of impact on building structures and the physical state.
Learning outcome: applying knowledge and understanding
- Ability to choose the most resistant building materials and structural solutions depending on the type and aggressiveness of the environment.
Learning outcome: formation of judgments
- Ability to justify the choice of corrosion-resistant materials adapted to a particular corrosive environment and develop design solutions that exclude corrosive wear.
Learning outcome: communicative abilities
- Ability to use normative and technical documentation in the design of corrosion protection.
Learning outcome: learning skills or learning abilities
- Ability to implement new ways and methods of corrosion protection, development of innovative design solutions.
Teaching methods
- Traditional technologies are envisaged for teaching: classroom lessons and students' independent work. Lecture course is presented in multimedia form. When presenting lecture material at the beginning and at the end of the lecture motivational speech is used. Text, audio and video information, graphs, tables, etc. are used in the lecture-presentation and practical classes.
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.

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 | |
| D | 1.0 | 50-54 | |
| FX | 0.5 | 25-49 | Unsatisfactory |
| F | 0 | 0-24 |
