AGRICULTURAL MECHANICS
Academic Year 2022/2023 - Teacher: Giampaolo SCHILLACIExpected Learning Outcomes
Knowledge of agricultural machinery and the main components, of the related regulations and techniques of use, in order to increase their effectiveness and conversely reduce the negative impacts on the environment and crops, the risks towards operators. Knowledge of the selection criteria based on the objectives of the intervention to be carried out, respecting the constraints imposed by agronomic aspects, product hygiene, environmental protection and operator safety.
Course Structure
Lectures, with presentations of case studies, technical examination, drafting of technical papers.
If teaching is given in a mixed formula or remotely, necessary changes may be introduced to what was previously stated in order to comply with the provided and reported Syllabus.
Learning assessment may also be carried out on line, should the conditions require it.
As a guarantee of equal opportunities and in compliance with current laws, interested students can ask for a personal interview in order to plan any compensatory and/or dispensatory measures, based on their specific needs and on teaching objectives of the discipline.
It is also possible to ask the departmental contacts of CInAP (Center for Active and Participatory Integration - Services for Disabilities and/or DSAs), in our Dept.

Detailed Course Content
The course deals with a first (short) part of mechanics elements; the second part concern agricultural machines (from seeding to harvesting), taking into account setting of machines for a correct use, their impact on environment and about safe aspects.

Learning Assessment
Learning Assessment Procedures
The evaluation of the oral interview is based on the relevance, correctness, comprehensibility of the answers, on the ability to make connections between the topics of the program and to report examples consistent with the topic under discussion, on the quality of the contents, on the property of the technical language .
Verification of learning can also be carried out electronically, should the conditions require it.
Examples of frequently asked questions and / or exercises
Adherence
