Course abstract

The aim of the study course is to investigate the geometric shapes forming the environment and their mutual relations, to find out the relevant regularities and apply them in solving practical tasks, to promote the development of the student's logical analytical thinking, visual spatial perception and creative abilities. To master the use of graphic methods. Learn to make and read drawings.

Learning outcomes and their assessment

Knows the methods of spatial projection of elements. Students acquire theoretical and practical knowledge of position and metric problem solving methods, as well as orient themselves in the construction of geometric elements, objects and their layouts - 1st and 2nd homework, 2nd test.

Is able to practically apply the standards set by the industry, is able to choose the necessary methods for solving tasks and perform the design of technical documentation. Can read and display simple drawings of geometric elements - 1st test and laboratory work.

Able to use the acquired professional knowledge and drawing skills in studies, practical work and the implementation of creative thinking. Able to independently develop and adjust constructive solutions - 1st and 2nd homework, laboratory work.

Requirements for awarding credit points

A test with a mark is formed as follows:
• developed and successfully defended laboratory works (80%);
• successfully passed tests (20%).

Description of the organization and tasks of students’ independent work

If necessary, the tasks started in the laboratory work must be completed independently, in accordance with the conditions. Presentation of the work takes place after its completion, during the laboratory work.
Homework 1 - Determining the true size of a pyramid section. Full surface layout.
Homework 2 - Determining the true size of a cone section shape. Full surface layout.

Individual independent practical studies, in-depth study of test topics.

Criteria for Evaluating Learning Outcomes

The assessment of the study course test depends on the cumulative assessment of the study course laboratory work, homework and tests.
The test mark is calculated as the arithmetic mean of two tests and the average semester mark, which is calculated as the arithmetic mean of the marks of laboratory work and homework taken in the study course.
A student obtains a successful grade for laboratory work and two homeworks if the work is presented and at least 40% of the conditions for the development of work are met.
A student obtains a successful grade for a test if at least 60% of the tasks have been solved correctly.
