Teaching method

There are two hours of lectures, one hour of preparation for the lab exercises and a lab session of two hours each week.

Lectures are problem-driven. They start with a concrete problem, which motivates the presentation of some computer systems topic, some data type or some programming language construct, and end with the complete source code of a program that solves it.

In the lab classes, students design, implement and test programs for solving simple problems in Science and Engineering fields.

Evaluation method

Evaluation Rules

Assessment Components

The assessment consists of two components: the laboratory component and the theoretical-practical component.

***** Laboratory Component and Frequency *****

The laboratory component consists of two practical assignments, carried out in a group of two students (or individually, in justified cases) outside the class period, with the work being partially carried out in a practical class.

The evaluation of the works is done individually, during the corresponding tests, which will include a group of questions related to the respective works. The evaluation of these groups depends on the final grade given to the works, but not on the test grades.

The grade of the laboratory component (CompL) is obtained by the weighted average of two practical assignments (TP1 and TP2):
 
    • CompL = 0.4 TP1 + 0.6 TP2.

To obtain frequency it is necessary that CompL ≥ 8.0.

***** Theoretical-Practical Component *****

The theoretical-practical component consists of two tests (during class time) or an exam (at the time of recourse). The three tests are individual, written and without consultation.

The grade of the theoretical-practical component (CompTP) is the arithmetic mean of the test scores (T1 and T2) or the exam grade (Ex):

    • CompTP = max (0.5 T1 + 0.5 T2 , Ex).

To obtain approval, CompTP ≥ 8.0 is required.

*****   Final grade   *****
The final grade (NF) of students with frequency is calculated as follows:
    • NF = CompTP,                     if CompTP < 8.0;
    • NF = 0.4 CompL + 0.6 CompTP,    if CompTP ≥ 8.0 .

All grades are rounded to the nearest decimal, on a scale from 0 to 20, except for the final grade (NF) which is rounded to the nearest integer.

***** Rankings Obtained in Previous Years *****
Students who have attended UC since the year 2018/19 (when the Python language was used) can keep this grade.
If they want to keep the previous frequency, they must not enroll in practical classes and this grade corresponds to the CompL above. If they enroll in practical classes, the CompL grade will be the grade obtained this year (2021/22).
