Assessment methods

Concerning the teaching unit Heat Transfer (Graduate Course) the exam consists in an oral test. The test is oriented to the evaluation of the achievement of the capability to formulate, from a physico-mathematical viewpoint, and solve problems of heat conduction. The test is also oriented to the evaluation of the achievement of an appropriate knowledge on the basic topics of the course under the theoretical perspective. The final mark, less or equal than 30 (positive outcome is greater or equal than 18), expresses the overall evaluation on the theoretical knowledge and on the practical ability with respect to problem solving.

The final mark on the entire integrated course made of Heat Transfer (Graduate Course) and Heat and Fluid Flow (Graduate Course) is the arithmetic mean of the marks obtained in the two separated exams: Heat Transfer (Graduate Course); Heat and Fluid Flow (Graduate Course). The partial mark in one of two modules of the integrated course is valid for twelve months. If within twelve months the student does not pass the exam on the whole integrated course, the mark on the single module loses its validity.
