Learning outcomes
The course aims at giving students the principles and the fundamental concepts of Soil Mechanics. At the end of the class, the students understand the behaviour of soils as engineering materials and the main experimental methodologies for the determination of their physical and mechanical parameters. The final goal is to provide a sound basic knowledge for solving simple geotechnical problems as well as for carrying out the subsequent work on Geotechnical Engineering.

Teaching methods
Each lesson will start with a theoretical overview of the key concepts, followed by their application through guided problem-solving activities conducted collaboratively by the professor and the students.
Assessment methods
Assessment is based on a final exam, aimed at assessing the understanding of concepts and the acquisition of related competences. The exam consists of a preliminary written test, which requires the solution of numerical exercises, and a final oral session, which deals with more theoretical issues. The exam, in both written and oral parts, concern all the topics developed during the lessons.
Higher grades will be awarded to students who can demonstrate an organic understanding of the subject, a capacity of presenting the course contents in a clear and concise way and an ability of critically discussing the results achieved. To obtain a passing grade, students are required to show their knowledge of at least the key concepts of the subject, some ability for their critical application and a correct use of technical language. A failing grade will be awarded if the student shows knowledge gaps in key-concepts of the subject, inappropriate use of language, and/or logic failures in the analysis of the subject.
