## Learning outcomes of the course unit

1. Knowledge and understanding skills

Understand the basic aspects of classical physics and the physical laws ruling it.

Recognize and exemplify the fundamental laws of Classical Physics, Dynamics, Thermodynamics and Electromagnetism, with particular attention to the principles of conservation.

Explain the meaning of the introduced physical quantities

Remember the fundamental units of measurement

Compare physical systems by detecting analogies and differences

Deferring from direct observation of a simple phenomenon the physical laws that describe it

2. applying knowledge and understanding

Apply the known physical laws to describe the system in question

Apply known physical laws to symbolically set up simple problems

Perform dimensional analysis

Apply the acquired knowledge to expose the relationship between physical quantities

Perform simple exercises with related numerical calculations

Students should be able to orient themselves in the evaluation of analogies and differences between physical systems and the understanding of physical laws. They must have acquired the ability to understand the laws of classical physics in the essential aspects, to perform simple exercises with a reasonable degree of autonomy, to statistically process and measure the results of experiments and to summarize the problems in their essential aspects.

3. Autonomy of judgment

Know how to interpret data for a problem

Know how to analyze definitions

Know how to critically evaluate the validity limits of the developed physical models

Know how to recognize the correct formulation of physical laws.

Know how to attribute a reference frame of physical laws to each phenomenon under investigation

Students at the end of the course will have to demonstrate that they have improved their critical skills and judgment formulation, in particular to interpret the data of a problem, to reflect on the phenomena that they observe, to study independently, to communicate ideas-problems-solutions So to develop those learning skills that are necessary to undertake subsequent studies in the field of biophysics or to engage in related professional activities.

4. Communicative Skills

Be able to explain the Physical Laws of Mechanics, Thermodynamics, Electromagnetism in a clear, synthetic and effective way

5. Learning Skills

Study independently

Link different topics discussed in the course and topics addressed in other subjects (Chemistry, Mathematics, Biology)

Evaluate your degree of understanding by trying to solve similar problems but not identical to those already dealt with in lesson

Read basic texts and even more advanced levels with a reasonable degree of autonomy

Know how to change your conceptual framework in the face of simple problems that you can not immediately determine the solution

## Teaching methods

Teaching activities will take place with lessons, sometimes alternating with a Socratic heuristic approach. The topics discussed will be punctually accompanied by examples and simple exercises that allow the student to understand how to apply the concepts outlined.

Each week, two hours of tutorials will be held within the Idea project, designed to help students with physical education debt in the entrance exam and provide opportunities for exercises on lecture topics.

The slides used during lessons will be uploaded to Elly before the beginning of the course.

The course slides are considered an integral part of the reference material.

It is recommended that non-attending students check the available teaching material and the instructions provided by the teacher through the Elly platform.

## Assessment methods and criteria

The TOLC-F test, developed within the CISIA inter-university consortium, and adopted as access test to the course of studies in CTF for the academic year 2018/2019, will also serve to establish the OFA (Additional Educational Obligations), i.e. the training debits of every student admitted to the CdS of CTF.

As indicated on the admission notice, the score threshold that will determine the assignment of OFA for Physics is 3 out of 7.

For students with OFA in Physics, a support course (Idea Project) is offered to facilitate the recovery of educational debt. Approximately halfway through the semester a test will be given to evaluate the recovery of the educational debt. An additional trial will be given at the end of the semester.

It is not possible to take the exam, the methods of which are described below, if not after having recovered the educational debt.

The summary appraisal of the learning involves a written examination, including 30 closed-ended questions, aimed at assessing the understanding and ability to apply the laws of physics. The duration of the test is 1 hour. Assigning the test score (0-30) is done by counting the exact answers.

During the course 2 partial tests are given, the passing of which allows you to have a bonus point for each test, for a maximum of 2 points, which is summed up to the score obtained in the written test.

Upon completion of the written test, the student may eventually complement the examination with an oral test to improve the score obtained.

To assist in the preparation of the written test, Elly is provided with exemplifying evidence.

Students can use scientific calculators during the test.

Scores will be published on esse3.
