Course abstract

The aim of the study course is to present the methods and ways of evaluation of the economic efficiency of agricultural machinery, including calculation of machine costs, machinery exploitation, economic evaluation of technological lines and production objects.

Learning outcomes and their assessment

Knowledge - on ways of evaluation of the economic efficiency of agricultural machinery, comparing the existing and the new technological solution as well as several new solutions. Knowledge is assessed in laboratories and practical work, as well as in tests.
Skills - to know the technological processes of livestock production, as well as to develop their modernization projects in order to improve the quality of the produced products and achieve high work results. Skills are assessed in practical work and tests.

Competence – to acquire knowledge and skills to be able to evaluate the economic efficiency of application of agricultural machines in definite conditions of production. Competences are assessed in laboratory work and tests.

Requirements for awarding credit points

The type of test is a test with a mark. In order to receive the test, it is necessary to have developed practical work and written tests with a positive evaluation.

Description of the organization and tasks of students’ independent work

Preparation for tests using the literature indicated in the study program and consulting with the lecturer of the study course.

Criteria for Evaluating Learning Outcomes

The evaluation of the study course exam depends on the average evaluation of the study course tests. A student can obtain a successful assessment of the test if at least 50% of the test questions are answered correctly. The examination mark is calculated as the arithmetic mean of the average results of the passed tests.
