Teaching methods
The following interactive technologies are used in studying the discipline: the method of assignments, the method of presenting information, the method of remote sensing. Lectures are given using multimedia equipment. Each lecture is accompanied by showing lecture demonstrations (slides and video clips). To master the discipline, interactive databases, space images of different resolutions, topographic maps of different scales are used. During practical work, a trip to natural areas and work with modern city plans and maps is carried out. In combination with extracurricular work this contributes to the formation and development of professional skills of students.
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.
