Course abstract

The aim of the study course is to investigate the geometric shapes forming the surrounding environment and their mutual relations, to find out the relevant regularities and to apply them in solving their practical problems, to encourage the student to develop logically analytical thinking, visual spatial perception and creative ability.

Learning outcomes and their assessment

Knowledge - understanding of spatial projection methods 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.

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

Competences - is 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 the constructive solutions of the equipment - 1st and 2nd homework, laboratory work.

15. Cone cutting with a plane. Determining the true size of the cutting section of a cone. Development of a cone (Lecture - 1h, 2nd homework).
16. 2.Test work: surface cutting with a plane. The actual size of the cutting area (Laboratory works - 1h).

Requirements for awarding credit points

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

Description of the organization and tasks of students’ independent work

The tasks set in the laboratory works must be completed independently, in accordance with the conditions specified in the laboratory work. Presentation of the work takes place after its completion, during laboratory work.

1st homework - Determining the true size of the cutting section of a pyramid. Development of a pyramid.
2nd homework - Determining the true size of the cutting section of a cone. Development of a cone.

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

Criteria for Evaluating Learning Outcomes

The evaluation of the study course test depends on the cumulative evaluation 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.
