Methods of Provision

Conventional

Teaching Methods

The teacher holds lessons on theoretical topics which are constantly followed by calculation exercises that allow the student to continually self-check his learning process. During the lessons and exercises the student is encouraged to participate directly through questions and requests for further information on the topics covered.

Evaluation methods

Verification of learning:

MODULE 1 [Prof. Zazzini]

The preparation of the students will be verified orally. An in-depth knowledge of the topics both at a theoretical level and through calculation exercises or through the analytical or graphic solution of problems will be required, with particular attention to those relating to the thermo-hygrometric behaviour of buildings. Special emphasis will also be given to verifying the abilities acquired by students in identifying the most effective procedures for analysing phenomena, identifying problems and proposing solutions, always with particular attention to the issue of the energy behaviour of building structures. The evaluation will be made explicit by a vote expressed in 30/30

MODULE 2 [Prof. Montelpare]
The exam grade is expressed in 30/30. The course offers the optional possibility to do four intermediate partial test, that allow to have a partial or total exemption of the final oral exam. The final oral exam consists of applied exercises from which theoretical questions are formulated on the course arguments.
