Metodi didattici
Teaching activities will include theoretical lessons supplemented by specialized websites and videos viewing. Lessons will also include critical reading of scientific, provided by the teacher. Student-teacher interaction will be encouraged and privileged in order to develop a critical knowledge of the topics. The slides (in PDF format) used to support teaching will be provided to students as part of the study material, lesson by lesson. They will be uploaded in the dedicated platforms. Slides are provided for studying but they cannot used / disclosed for other purposes.
Modalità verifica apprendimento
The assessment of knowledge will consist of an oral examination with questions on main topics. During the oral test the knowledge on the bioprocesses, raw materials, fermentation systems and the ability to communicate by technical and appropriate language.
DETAILED EXPLANATION: An oral exam is scheduled at the end of the course (no intermediate assessments are provided) and this will take place over the course of the educational calendar of the training offer. For each exam, the student who intends to take the test must register using the Esse3 platform.
The interview, lasting about 30-40 minutes, will be semi-structured and composed of 3 general questions on as many parts of the course. The indicators (ascertained characteristics) for the evaluation of the oral exam are:
- ability to use and connect knowledge (30%)
- ability to discuss and deepen topics (40%)
- mastery of scientific-agronomic language (30%)
The evaluation is expressed out of thirty and the final score will progressively reflect the different achievement of the evaluation indicators:
18-20: elementary knowledge of the proposed themes, sufficient expressive skills;
21-23: basic knowledge with no in-depth elements; expression not always appropriate;
24-26: good knowledge, in-depth elements at the request of the teacher with answers that are not always complete and detailed;
27-29: very good and satisfying knowledge; expressive skills and adequate and well-articulated argumentation in an autonomous way;
30 and 30 / honors: solid, complete and adequate knowledge; critical application of the presentation of the arguments, use of an appropriate technical-scientific language.
