It is possible to use different books, if appropriate to the course contents.
The slides of the lessons will be given, as well as a collection of exercises for practice workout.
Teaching methods
Oral lessons in the classroom. In the lessons, the topics of the classic physics will be presented and explained. The arguments will be completed by several examples and exercises to the aim of both understanding the possible applications of the explained concepts and solving problems (of the same kind as those seen during the lessons). In the classroom will be shown, as possible, demonstrative experiments or web applet.
For the oral lessons, the teacher will use some slides that will be part of the educational material. These slides will be uploaded on the "Elly" platform some days before the beginning of each new argument. These slides, however, have to be integrated with textbooks and with the notes that students take during the lessons. To download the slides, the on-line registration to the course is needed. A collection of exercises to practice workout will be given.
Students that have not obtained the minimum marks in the initial test must follow the lessons of "IDEA" project (see below in "Altre informazioni").
Students have to check on the "Elly" platform the availability of the educational material and the notices from the teacher.
Assessment methods and criteria
Written exam in presence. It consists of 3 problems and 5 questions (both multiple choice and open question); the student must explain their answer exhaustively. The maximum mark will be 30. Laude will be given if the maximum mark will be obtained, together with the use of a good terminology. Exam will be passed with a minimum mark of 18. However, also mark between 15 and 17 will be assigned; in such a case, the student must perform an oral exam. The marks under 15 will be classified “insufficient”, which means that the student have not passed the exam.
Students can use a pocket calculator only.
The written exam will last 100 minutes. At the end of the exam, the teacher will explain the resolution of the problems and the answer to the questions.
The students can improve the final evaluation with an oral exam, that, in case, will be performed in a couple of days after the publications of the exam score on the "Elly" platform. After this date, the exam score will be published on the "ESSE3" platform.
The students can see their performance after taking an appointment with the teacher.
Partial proofs in itinere:
During the course the students could take two partial proofs, at the end of each of the following arguments: mechanics+fluids; thermodynamics+electromagnetism+optics. The data of the proofs will be communicated on the “Elly” platform, on which the students will sign up to each proof. Also in this case, the proof consists of a written exam, with 4 problems and 5 questions (both multiple choice and open question); the student must explain their answer exhaustively.
Rules for the partial proofs:
- Marks from 15 to 30 will be assigned. The marks under 15 will be classified “insufficient”.
- With a mark “insufficient” in one of the proofs, the student cannot obtain the exoneration from the final exam.
- If the mean of the marks obtained in the two proofs is 18 or greater, the student will obtain the exoneration from the final exam and the mean of the marks will be registered as final marks after the registration on the “ESSE3” platform, but only when the student have taken the exam of Mathematics.
- If the mean of the marks obtained in the two proofs is less then 18, the student must take an oral exam.
The results and the mean of the two proofs will be previously uploaded on the “Elly” platform, with the indication of the possible exoneration form the final exam.
Also if the student has obtained a positive results, he can take the oral examination to improve the final evaluation.
Students that want to register to the degree course in Pharmacy must pass an initial test (TOLC-F). Students that register to the degree course in Pharmacy without obtaining the minimum marks in Physics, must attend the lessons of the IDEA project (see below).
Other information
The course takes part in the IDEA Project, benefitting by the help of a high school teacher that, in a dedicated time (two hours at a week), will go thoroughly into the exercises and problems. This project is useful for each student, but it is particularly addressed to the ones that have not obtained the minimum marks in Physics in the initial test.
