To memorize essential formulae, grouped in a document composed by the teacher; to understand the text of a problem and of theoretical questions;
D2 - APPLYING KNOWLEDGE AND UNDERSTANDING
To correctly employ formulae and concepts; to be able to autonomously solve physics problems, aplied to the proposed topics; to be able to understand the text of a problem and of theoretical questions;
D3 - MAKING JUDGMENTS
To be able to analyze physics problems and evaluate the simplest and most time saving way to solve it; to know how to answer questions on the physics programme in a critical way
D4 - COMMUNICATION SKILLS
To be able to answer questions in a synthetic and rigorous way; to be able to express in an immediately understandable language concepts and comments to multiple answer questions; to ask the teacher for help when needed;
D5 - LEARNING SKILLS
To be able to identify the best studying methodology and to change his/her approach to face problems and questions of physics, in case the results are not those desired; to be able to judge if basic mathematics, needed to solve physics problems, is sufficiently mastered.

Teacher's slides

## Teaching methods

Lessons will be given in presence and supported by videorecorded materials. Teaching activities will be carried out via slide-based lessons and exercises. We will use for exercises the Wooclap platform (smartphone with QR code reading is necessary) that ensures a high degree of interaction between students and teacher, and allows to give your answers anonimously. Slides will be uploaded in advance on the Elly platform once a week. To download the slides it is necessary that students subscribes to the the course at the elly platform. Slides are considered integral part of the teaching material. Teaching methods and exam modalities could change, due to the SARS-CoV-2 emergency. Variations will be communicated in due time.

## Assessment methods and criteria

Written examination, built of 11 mutiple choice questions. Each completely correct answer has a value of 3 points (33 points = 30 cum laude; it is worth 31 for the average with the other modules); no penalties for uncorrect answers. Teaching methods and exam modalities could change, due to the SARS-CoV-2 emergency. Variations will be communicated in due time.
Students with SLD, SEN or disability must send request in order to be able to take advantage of compensatory and / or dispensatory measures during the examination at least 10 working days before the scheduled date for the examination. Request, by e-mail, must be addressed to the teacher of the course and, in cc, to the Contact person of Department (contact persons list and their email aivable at the following address: http://www.cai.unipr.it/it/student-con-dsa-e-con-bes/42/ ) and to the Reception and Inclusion Center (cai@unipr.it )

Students will be received on thursday (10:30-12:00) at the Physics building (Campus) or via the Teams platform. The teacher will further be available for half a hour after the Physics lesson, at the Dept. of Veterinary Science. For further information and questions the teacher is available via e-mail at aba.losi@unipr.it
