Teaching method

The problem-solving sessions consist of a presentation of the subject, along with illustrative examples.

Practical classes consist of problem solving and analysis. Students will be required to previously prepare exercises that will be presented on the board for the class, with subsequent group discussion. These exercises will be chosen from a list provided by the teachers.

Any doubts are clarified during classes or in sessions designed to assist students or even in sessions arranged directly between student and teacher.

Evaluation method

The Continuous Assessment of the curricular unit comprises:

Theoretical-Practical Assessment: two written tests, each lasting 1h30 minutes, to be carried out during the semester. Each test will be classified between 0 and 8 values.

Summative Assessment: delivery of solved exercises. In each class, two exercises will be choosen to be delivered the resolution in the next class. Among all the students who deliver the resolution, two will be chosen to present their resolution on the board. The final grade for this component, between 0 and 4, will be assigned by the teacher based on the quality and quantity of resolutions delivered. In this evaluation component, more than a correct resolution, the student''s work will be valued.

Frequency: Frequencyis obtained by delivering solutions for the exercises in more than 5 classes. Students with student-worker status and students who attended the previous edition of the curricular unit are exempt from obtaining it. Only students with Frequency will have final classification in the curricular unit.

A student who meets the Frequency criterion will have a final classification by Continuous Assessment equal to T1 + T2 + AS, rounded to the nearest integer. Where T1 and T2 are the final grades of the first and second test, respectively, and AS is the Summative Assessment grade. The student will obtain approval in the curricular unit, by Continuous Assessment, if this classification is equal to or greater than 10 values.

Final Exam: Students who have not been approved by Continuous Assessment and who have obtained Frequency of the curricular unit, can take an Final Exam. This is a written exam, lasting 3 hours, which evaluates all the contents taught in the curricular unit. The exam is divided into two parts, each one classified from 0 to 8 values, whose evaluated material corresponds, respectively, to the first and second test. The final grade will be T1 + T2 + AS, where T1 and T2 are the final grades of the first and second part. The student is approved if it is greater than or equal to 10 values.

Classification Improvement: Students approved in the curricular unit may request, upon compliance with all the conditions imposed by NOVA FCT, Classification Improvement by taking the Final Exam. The final grade will be T1 + T2 + AS.

On the day of the test, students must present themselves with a blank test booklet, writing material and official identification document. All tests and examinations must be carried out without consultation and without the use of any computational calculation material.

Working students, or other students who for some reason cannot attend practical classes, can ask the teacher to be evaluated without the Summative Assessment component. In that case the final Continuous Assessment or Exam grades will be calculated according to the formula (T1 + T2)5/4. In this situation the Frequency is given automatically. Attention: this request must be made by the end of the second week of classes, otherwise the student will be assessed with the Continuous Assessment component.

In any omitted situation, the NOVA FCT Assessment Regulation, of 31 July, 2020, applies.
