Welcome to Experimental Physics 1, the first physics course of the Chemistry Bachelors. As the instructor for this course, I look forward to helping you gain knowledge and develop methods that will be useful in your career. My goals for this course are to provide you reasoning and problem solving skills, confidence, knowledge, and technical expertise that will help you in your curricula and in your profession. In particular, I hope to help you learn how to use scientific reasoning to reach informed decisions in real-world situations.
(KNOWLEDGE AND UNDERSTANDING) acquire the basic knowledge on the foundations of classical mechanics: kinematics, dynamics, oscillations and waves.
(SKILLS) learn how to define a solution of a problem as a procedure to develope. In particular, you will be trained to solve a problem starting from a qualitative analysis classifying it on the basis of structural characteristics rather than on superficial aspects. You will be able to solve problems through the use of several tools as graphs, diagrams, limits, conservation laws.
(SELF-JUDGEMENT) be continuously stimulated to develope a critical approach on the understanding, the elaboration, and the use of concepts. You will acquire the ability to establish in a self-confident way if the results makes sense (use of "common-sense").
(COMMUNICATION SKILLS) learn how to present ideas organizing their knowledge hierarchically. You will learn how to simplify complex problems in their essential terms. Through the organization of the lectures, you will be trained to compare their ideas with your mates illustrating possible solutions to peers.
(LEARNING SKILLS) develop a methodology of study and analysis that will allow you to interprete and delve into problems of classical physics that will be encounter through your studies.

48 hours of lecturing activity
and tutoring activity modules
Teaching is in presence, it could be delivered online or in mixed mode based on the sanitary situation.
Didactic interaction methods and techniques in presence and online:
- classroom dialogue requested by the teacher, in presence or via chat
- combination of frontal and interactive teaching with the use of IT tools and different supports (video-projections and blackboard)
Integrative teaching methods and techniques:
- student teacher interaction: Communication by e-mail or meetings on a multimedia platform
- interaction between contents: Video and pdf of the lessons on sites indicated by the teacher
If deemed necessary by the teacher and at the request of the students, it will be possible to do an ongoing test
Verification of learning
To set up the monitoring and evaluation:
- Possible ongoing written test
- Written test and oral exam.
For the criteria for awarding the final grade:
- We shall assign defined grades to the portion of the written test as to the part of oral presentation.
The results of these assessments will determine the overall evaluation of the student.
