Assessment methods

Module "Industrial Microbiology": Learning content from the students was found during the course, through questions and insights. At the end of the same it will be made an oral examination, both on topics discussed during the course, through the presentation of a paper in the form of theme. In it the student will analyze an industrial microbiology article selected on the basis of the arguments developed during the lessons.

Module "Fermentation" Chemistry: Learning content from the students was found either during the course, through questions and insights, that at the end of the same, through a) the presentation of a paper in the form of theme in which ' student elucidates 3 or 4 main topics of the course, b) the establishment of a review work on a topic chosen from those discussed in class, c) a final talk on topics discussed during the course.
