MECCANIZZAZIONE E DIGITALIZZAZIONE DEI PROCESSI PRODUTTIVI AGRICOLIModule MACCHINE AGRICOLE ED ELEMENTI DI FISICA APPLICATA
Academic Year 2024/2025 - Teacher: Giampaolo SCHILLACIExpected Learning Outcomes
Ability to apply knowledge and understanding abilities, becoming able to make conversions between the units of measurement of different systems (International System and Technical System) in professional consultations and field situations, to apply knowledge of physical quantities in concrete field and construction site situations, to competently select agricultural machinery according to objectives.
Making judgment in the selection of agricultural machinery and use procedures according to the knowledge learned during the lectures and exercises included in the Course.
Communication skills are developed during lectures, exercises, and Exam Simulations, during which the Student comes into contact with and then uses the appropriate terms and learns to use language consistent with the Discipline.
Learning skills is an implicit objective of the Course, which aims to impart useful elements to face the world of work and higher level studies.
Course Structure
In case the teaching is given in a blended or distance mode, the necessary variations may be introduced in order to comply with the syllabus provided and given in the syllabus.
During the exam, the technical paper that each student will write from the classroom exercises will be discussed.
Verification of learning may also be carried out electronically, should conditions require it.
Information for students with disabilities and/or learning disorders.
As a guarantee of equal opportunities and in compliance with current regulations, students can ask for a personal interview in order to plan any compensatory and/or dispensatory measures, based on their specific needs and on learning objectives of the discipline. It is also possible to refer to the departmental contacts of CInAP (Center for Active and Participatory Inclusion - Services for Disabilities and/or learning disorders)
If conditions require teaching given in a hybrid mode or remotely, necessary changes may be introduced to what previously stated in order to comply with the program.

Learning Assessment
Learning Assessment Procedures
Final oral exam.
During the exam there will be a recognition of the agricultural machinery studied in the course.
Evaluation of the oral interview is based on relevance, correctness, comprehensibility of answers, ability to make connections between program topics and report examples consistent with the topic under discussion, quality of content, and ownership of technical language.Exercises are available on Studium. Simulation of Examination without classroom or telematic grading.
Verification of learning may also be conducted telematically, should conditions require it.
Negative:
Knowledge and understanding of the topic: Important shortcomings. Significant inaccuracies
Ability to analyze and synthetize: Irrelevant. Frequent generalizations. Inability to synthesize
Use of references: Completely inappropriate
18-20:
Knowledge and understanding of the topic: At the threshold level. Obvious imperfections
Analysis and synthesis skills: Just enough skills
Use of references: just appropriate
Topics are expounded, but incompletely, and the examination proceeds through supportive interventions by the lecturer
21-23
Knowledge and understanding of the topic: Routine knowledge
Ability to analyze and synthesize: ability of correct analysis and synthesis. Argue logically and consistently
Using references: Use standard references
Topics are expounded in an overall sufficient manner through moderate supportive interventions by the lecturer
24-26
Knowledge and understanding of the topic: Good knowledge
Analysis and synthesis skills: good analysis and synthesis skills. The arguments are consistently expressed
Using references: Use of standard references
27-29
Knowledge and understanding of the topic: Knowledge more than good
Ability to analyze and synthesize: considerable abilities of analysis and synthesis
Use of references: the topic has been explored in depth
30-30 e lode
Knowledge and understanding of the topic: Excellent knowledge
Ability to analyze and synthesize: excellent abilities of analysis and synthesis.
