### SDGs

This teaching activity contributes to the achievement of the Sustainable Development Goals of the UN 2030 Agenda. ## Learning outcomes

Mathematics: The students will be able to operate with real numbers, to understand the algebraic calculation and the basic properties of the geometrical figures. The student will be able in general to: use the mathematical knowledge and the mathematical tools; to set and solve problems; to learn new concepts on the base of its experience and the previous knowledge. In Statistics the student will learn the main methods and tools for the qualitative and quantitative inferential and descriptive  analysis. In particular: interpret and critically evaluate the statistical information; produce and process raw data; apply the statistical approach to the natual and social sciences topics related to animal production.

In Physics: the student will learn the meaning of the different units of measure; the meaning of the basic physics terms; the basic principls of physics; the student will then be able to follow the successive courses of physiology, food technology, animal production related buildings and machinery.

## Teaching methods

Classroom lessons and group works on case studies

## Assessment methods

The final mark of the integrated course will be calculated as an arithmetic mean of the three different modules.

Concerning the module on Mathematics, the exam includes a written and an oral test. The written one is further divided into two parts: the first is a brief quiz to assess the knowledge of basic concepts, and the second part is a more thorough examination that includes the resolution of some exercises. The oral test is optional, though it is necessary in order to achieve a final grade higher than 28.

The module Staitstics will involve a written test with both multiple choice quesitons and open quesitons.

Ther module Physics involves an oral examination (approximate duration: 30 minutes) during which the understanding of the Mechanics of the material point, of the Fluid Mechanics, and of the Thermodynamics will be assessed.

The marks in each module will be valid for 3 years. That is after the first module exam results the student will have three years to finalize the exams for the remaining two modules of  the integrated course

## Teaching tools
