Teaching methodology

The teaching of the course is structured in theory/problems sessions and laboratory sessions.

Theory/problems sessions: 2 hours per week.
The instructors can present some of the course content using slides or other material available at Atenea. Problems will be aimed to help and test learning. Sometimes, students may be required to have fully or partially solved problems before class, so the possible solutions will be discussed in class. At other times, the problem will be raised and resolved during class, using cooperative learning techniques. There will be also sessions in which students will be required to prepare on their own and present to the class a certain topic.

Laboratory sessions: 2 hours per week.
During the first 4 weeks of the course, and after a brief introduction, the students will be required to complete a certain number of tasks using the computer in accordance with a work plan.
Durant the remaining weeks of the course, the students, in groups of 3-4, will design and implement a web project. The lab sessions will be used to work in the project, discuss and fix doubts and problems, plan and manage goals, and present results.

Evaluation methodology

Final Grade = 50% NTP + 50% NLAB

NTP = theory and exercises mark
NLAB = laboratory grade mark

NTP is computed from C1 (Test 1), C2 (Test 2), P1 (Presentation 1) and P2 (Presentation 2) marks applying the following formula:

NTP= 30% C1 + 30% C2 + 20% P1 + 20% P2

NLAB is computed from IntroLAB (Introductory sessions to web technologies) and Project marks applying the following formula:

NLAB = 30% IntroLAB + 70% Project

Presentations (P1 and P2) and Project involve group work. In these cases, the student will have a personalized note that will be calculated based on the assessment that the teacher will make on the overall quality of the item (presentation or project), the assessment that the teacher will make on the student's contribution within the group and the assessment that the fellow group members will make on the contribution of the student to the group.

The assessment of the transversal competence assigned to the course (G7.3) is obtained from the following formula:

Numeric G7.3 Grade = 60% Project + 40% ((P1 + P2) / 2)

And will have values A, B, C, D according to the following distribution:

G7.3 Grade = A if Numeric G7.3 Grade is in [8.5, 10]
G7.3 Grade = B if Numeric G7.3 Grade is in [7, 8.4]
G7.3 Grade = C if Numeric G7.3 Grade is in [5, 6.9]
G7.3 Grade = D if Numeric G7.3 Grade is less than 5
