Students can find the pdf of lessons on the Elly (http://elly.veterinaria.unipr.it/2017/)platform or get them directly from the lecturer.
Teaching methods
Lectures will be conducted in presence and contextual transmission in teleconference on the authorized web platform, depending on the sanitary situation and following the current regulations. Lectures will be held hrough the aid of a POWER POINT support.
The power point presentations used to support the lessons will be directly provided by the lecturer to students.
Power point presentations are considered an integral part of the didactic material. Any changes made to the presentations will be promptly reported by the lecturer during the lessons.
Recorded lessons will be available on the Elly platform for 3 days after each lesson.
Assessment methods and criteria
Learning evaluation will take place through summative assessment.
Mode and type of test: written test with closed multiple-choice questions, maximum duration of 35 minutes; the number of questions is 31.
Scale of assessment: the scale of assessment ranges from 0 to 30 cum laude.
Weights and evaluation criteria: Each correct answer has the value of n. 1 points; Unanswered or wrong answers have a value of 0; the 31st correct answer allows the achievement of the laude.
Materials useful to support the test: no paper or electronic material is allowed.
Methods for returning test results: the test results will be sent via email by sending a list listing the serial number of each candidate to which the evaluation will be compiled according to the criteria set.
To the students with diagnosis of specific learning disability (DSA) certified under law n. 170/2010, proper specific support will be provided.
The examination, if not otherwise communicated, will be held in an on-line form.
