Learning outcome: formation of judgments

• To understand the modern understanding of the physical picture of the surrounding world and the state of scientific and technological progress; to use the knowledge of physical laws and phenomena for a competent judgment of man-made processes occurring in nature and society.

Learning outcome: communicative abilities

• The ability to work in a team, the ability to navigate the flow of new scientific and technical information, to master new advanced technologies and participate in their creation, to be ready for geographical and social mobility in the face of increasing dynamism of change and uncertainty.

Learning outcome: learning skills or learning abilities

• Have the skills of conducting a physical experiment, working with measuring devices, calculating and processing the data obtained; find individual ways of self-education in the future.

Teaching methods

When conducting training sessions, the following educational technologies are provided: - interactive lecture (using the following active forms of learning: guided discussion or conversation; moderation; demonstration of slides or educational films; brainstorming; motivational speech); - building scenarios for various situations based on the specified conditions; - information and communication technology (for example, classes in a computer class using professional software packages); - search and research (independent research activity of students in the learning process); - the solution of educational tasks.

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.

The evaluating policy of learning outcomes by work type

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:

 

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:
