Methodologies
Methodologies Description
Problem solving Problem solving lectures where a problem to solve is exposed. First, the student tries to solve the problem for a while, considering different aspects to solve it. Finally, the problem is solved in the blackboard, showing the typical errors of the solutions provided by the students.
Laboratory practice In laboratory classes, teachers present the knowledge needed to acquire the proposed skills and students will do exercises that will lead them to develop their operative skills.
Mixed objective/subjective test It consists in a final exam that will contain both questions related to theoretical issues and problems to solve.
Guest lecture / keynote speech Classroom lectures. In them, the fundamental contents of the subject will be exposed. They are devoted to showing objectives, motivation, concept development, utility, and summary.

Personalized attention
Methodologies
Laboratory practice
Problem solving
Description
After proposing a problem, the teacher discusses with students the possible solutions and standard errors until a satisfactory solution is achieved.


In the laboratory, there will be (semi) personalized support. The teacher attends specific questions to each student or group.

Assessment
Methodologies Competencies Description Qualification
Mixed objective/subjective test A18 B1 B3 B4 Both at the FIRST OPPORTUNITY and in the SECOND OPPORTUNITY to pass the course, it is necessary to pass a conventional written test which will represent 75% of the global grade.

To pass the course globally it is necessary to obtain in the mixed test a minimum grade of 3.5 (over 7.5). If that minimum grade is not achieved, the maximum grade cannot exceed 4.5 (and therefore the course is failed)

Percentage: 75%
Top grade: 7.5 points
Minimum compensable Note: 3.5 (over 7.5)
75
Laboratory practice A18 A19 B1 B3 B4 C3 For the first opportunity, it has two components:

-SQL language Test on the computer in classroom practices (Percentage: 15% - Maximum grade 1.5 pt).

-Design a database (Percentage: 10% - Maximum grade 1 pt).

For the second opportunity, you can only recover or improve the grade of the SQL language test, by performing a series of written exercises added to the mixed test (Percentage: 15% - Maximum grade 1.5 pt).

Assessment comments
  •  In the FIRST OPPORTUNITY, students that do not take the written exam will obtain a grade of "Non presentado" (Absent).
  •  If a student passes the course in the FIRST OPPORTUNITY, he/she will not be able to be evaluated in the SECOND OPPORTUNITY for extra credit.
  • If a student fails the course in the FIRST OPPORTUNITY, he/she can retake the SQL language test, the written test or both in the SECOND OPPORTUNITY.
  • If a student decides to not retake a test, he/she will keep the grade for that test obtained in the first opportunity.
  • If a student decides to retake a test, the final grade for that test will be the one obtained during the second opportunity (which can be higher or lower than the one obtained in the first opportunity).
  • In the SECOND OPPORTUNITY, students that do not re-take any of the tests (written test and/or SQL language test) will obtain a grade of "Non presentado" (Absent).
  • ACADEMIC DISPENSATION: Students officially enrolled part-time who have been granted an official dispensation from attending classes, as stipulated in the regulations of this University, will be able to do (and submit) all (or part) of the practices by their own. In the case that the activities require specific equipment, or are scheduled for a specific date and time, a viable alternative will be provided, where possible, at their request.

    ADVANCED OPPORTUNITY: The assessment for the advanced opportunity will consist of a written exam that will compute for the 100% of the grade.
