Learning assessment procedures

APPLIED PHYSICS IN MAGNETIC RESONANCE AND QUALITY CONTROL
Written test, composed of 5 open-ended questions, on all the topics covered during the classes. For each response are assigned from 0 to 6 points. The test is designed to assess the comprehension of the subject by means of answer accuracy and text clarity. The estimated time for the test is 50 minutes and is not allowed to consult texts, PC or smartphone.
EQUIPMENT OF MAGNETIC RESONANCE AND TC
Written test, composed of six open-ended questions, on all the topics covered in class. For each response are assigned from 0 to 5 points, with the presence of a question that can lead to the achievement of the praise. The test is designed to assess understanding of matter connecting it to the modules that are found within the Integrated Course. The estimated time for the test is 40 minutes, is not allowed to consult texts, PC or smartphone
APPLIED PHYSICS TO TC AND QUALITY CONTROL – first part
Written test consists of 9 multiple choice questions (3 response hypotheses of which only one is true), plus an open question relating to topics covered in class.
The profit estimate for closed questions is carried out with the following parameters:
3.6 points for each correct answer, 0 points for no answer, - 1 point (less than one point) for each possible wrong answer. The assessment criteria of the open-ended questions are based on partial or full understanding of the student about the main topics covered in class and the skills, capacity for analysis and synthesis of the argument.
Duration of test: 30 minutes. It is not allowed to consult any didactic or electronic device material.
APPLIED PHYSICS TO TC AND QUALITY CONTROL – second part
Written test consists of 15 multiple choice questions (3 response hypotheses of which only one is true). Correctly answer all the questions it enables the achievement of the 30/30 assessment (2 points per question). There are three additional questions in order to achieve the praise. The estimated time for the test is 20 minutes. It is not allowed to consult texts, PC or smartphone.
THE FINAL VOTE RESULT FROM THE WEIGHTED AVERAGE OF VOTES GAINED IN EACH TEST, WITH ROUNDING IN EXCESS TO DECIMAL> 0.50.
