Learning outcomes

The course aims to develop knowledge of biology, biochemistry and genetics related to physiological and pathological processes in order to understand how health and disease changes in individuals at different stages of life. This knowledge will allow nursing students to understand which kind of cellular processes are common to all living organisms and in particular the basic mechanisms in the regulation of metabolic activity, reproduction and cellular interactions. Moreover the course will focus on the basic concepts of genetics, the most common genetic diseases, and their transmission rules.

Assessment methods and criteria

------------------------
MM: BIOCHIMICA
------------------------
To overcome the module of Biochemistry, students must demonstrate that they have understood the basic concepts of biochemistry, biological macromolecules and metabolic transformations. The exam consists of a written test with 15 multiple choice questions and 3 open questions, to be briefly answered in a limited space, covering the didactic content throughout the course. The final score will be expressed in thirty's (/30) and the module of Biochemistry will be passed if the overall assessment of the integrated course is greater than or equal to 18/30.
------------------------
MM: BIOLOGIA APPLICATA
------------------------
The assessment of learning outcomes envisages a written test to ensure knowledge of the topics under consideration. The written test potentially covers all the topics listed in the program. It is articulated in groups of question-related to the main themes of the course (life macromolecules, cell biology, cell interactions, genetic information flow, mendelian inheritance, human genetics). Items are formulated as multiple answer questions and open answer questions. The answer to each item requires knowledge of biological terminology, ability to interpret genealogy trees, ability to systematically connect knowledge of biology and genetic molecules, ability to describe and exemplify biological structures. The examination will be validated with a minimum score of 18/30. The overall evaluation of the answers to the questions is expressed in thirty/30. To help the student to understand the contents and the formulation of the items, the examination tests submitted in the previous year will be discussed in the classroom with the students of the following year.
