Assessment methods

Written examination with the aim to evaluate if the student has acquired the knowledge related to the topics that have been treated during the course.

The written exam will consist of 60 questions (either multiple choice questions or very short questions with open answers)(time:120 min); each multiple choice question will present a little number of alternatives and can have more than one exact answer.  In case of open questions, the answer must not exceed the available space. The score ranges between 0 (zero) and 1 (one) depending on whether the answer is exact and pertinent to the question. No answer will have a score equal to zero.The exam will be considered as passed if the total score is equal or above 36 points.

The student will not have the possibility to use textbooks, memos or data storage devices.

The final grade of the integrated course of Biotechnologies applied to animal production comes from the final evaluations of the different teachings that make it up, weighted on the CFU of each course.

EVALUATION OF STUDENTS WITH SPECIAL EDUCATIONAL NEEDS. Particular attention will be given to the evaluation of students certified in accordance with Law 104/90 and Law 170/2010, or students who are recognized as having a special educational need (BES).
