Prerequisites

There are no official prerequisites, but the student must master the notation of UML class diagrams, the object orientation concepts and their programming in some language, preferably Java.

Objectives

  • Once the purpose of a software has been determined through the analysis of requirements, software developers design a solution. This goes from the architecture of its components (classes, modules ...) to implementation in some programming language. This course covers mainly two key aspects of the design: object-oriented design, with emphasis on design patterns, and user interface design.
  • The learning method relies on a project (the practicum) or put another way, we 'learn to do': all concepts addressed in the theory are necessary in order to design and implement a software application, starting with a statement that plays the role of requirements document. The practicum is about the design and implementation (but not requirements analysis, testing, version control or quality assurance, which belong to other courses) of an application.

  2. Identify, manage and resolve conflicts.
  3. Design a user interface based on customer specifications .
  4. Identify the paradigm that best adapts to a design problem in a specific computer software system taking into account the accessibility, ergonomic, usability and security requirements.
  5. Design and document software solutions.
  6. Conceive network technology based systems, applications and services, including Internet, Web, e-commerce, multimedia, interactive services and mobile computers.
  7. Know and apply the specific software components for communications based computational problems.
  8. Maintain a proactive and dynamic attitude with regard to the development of one's own professional career, personal growth and continuing education. Be able to cope with adversities.
  9. Develop curiosity and creativity.
  10. Work cooperatively.
  11. Accept and respect the role of the various team members, and its different levels of dependence.

  • Theory classes In them, the teacher introduces the theoretical contents and gives useful references (books, articles, web pages) so that the student can then continue their learning, as well as develop the software application proposed. The slides used in these classes should not be taken as a the only source, because they are used to explain in a more agile way. Ina addition, you need to study the recommended books, and articles, open access book chapters and others that we will indicate.
  • Problem classes. In these classes we will mainly present and assess exercises, small design plus implementation problems, or the application of specific UX techniques.
  • Practical sessions. The students will have formed at the beginning of the course small groups. In the practical classes students come to 1) show their work to the instructor and pose questions, and 2) given that the practice will be divided into milestones, the weeks that correspond to a milestone, it is evaluated The corresponding part in situ, according to a scale that will be included in the practicum handout. Therefore, the practical sessions are *not* for doing the practicum.

In order to present exercises and the practicum, each group of students must bring a laptop.

All the lecture notes, slides and more, plus the detailed schedule of the course are in Campus Virtual.

Annotation: within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.

Assessment

Continuous assessment activities

Title Weight Hours ECTS Learning outcomes
group assessment 50% 4 0.16 1, 3, 4, 5, 6, 7, 8, 9
individual assessment 50% 3 0.12 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11

The course follows a continued assessment system. This consists of a group assessment part and another individual assessment. The note of the first (PR) is obtained by making the marks of the practical goals (M1, M2, M3). The second (EX) of the average of two tests written during the quarter (EX1, EX2), or a retake exam (EXR1, EXR2). The suffixes 1 and 2 refer to the 2 parts of the course, before and after the first exam EX1.

The algorithm for calculating the final mark (FM) is the following (all marks are over 10):

// EX1, EX2 examens parcials

// EXR1, EXR2 examen de recuperació

// M1, M2, M3 notes de les 3 fites de pràctiques

// FM nota final

EX = ( max(EX1, EXR1) + max(EX2, EXR2) ) / 2.

if (M1>0) and (M2>0) and (M3>0) {

PR = (M1 + M2 + M3) / 3.

} else {

PR = 0.

}

if (EX >=5.) and (PR >=5.) {

FM =(EX + PR) / 2.

} else { // EX<5. o PR<5.

FM = min(EX, PR)

}

The practicum

  • The realization of the practicum is essential to assimilate the concepts of theory. The first thing we want to make sure is that the practicum has really been done by the group that delivers it, and that each member of the group has contributed to the same extent as the others. The second is that the practicum is done progressively during the course, in parallel with the theory. That's why we will do the following:
  • The mark for the practice is obtained by combining the grade of the parts into which it is divided. Each part will be evaluated in situ in one of the practical sessions that we will announce at the beginning of the course (the milestones). The points that can be obtained from each part will be specified in the handout. These assessments have no retake, afterwards.
  • On the evaluation days of the practicum (milestones), if as a resultof the answers to the questions posed by the teacher during the assessment, we have doubts about the authorship or contribution of some of member of the group, then the mark will change from group to individual and depending of how much and what part of the practice each member has done.

The exercices

  • We will propose some exercises that are optional. These exercises are done group, the same than the practicum (all or a subset of its members). The exercises may add points to the theory mark EX, with an upper bound of 10. We say 'may' because obtaining these extra points is conditioned to a validation test in order to verify that the student has effectively completed the exercise he has delivered. We will do these validation tests only once and they do not have retake afterwards.

Other

  • We do not preserve the mark of the practicum, exercises or exams from previous courses. Students taking again the course do not receive any differentiated treatment.
  • If an exam or part of the practicum is not delivered, the mark for that part is zero. The final grade will be ‘no-avaluable’ if nothing to be evaluated has been delivered, either exam, practicum or exercise.
  • Milestones are assessments equivalent to written exams. If a student does not show up, the mark is zero.
  • Only the students that are in the class when we assess an exercise will receive a mark.
  • MH marks will be awarded at the discretion of students with a final final grade of 9.0 and taking into account all kinds of work done (exams, practicum and exercises).
  • The dates of continuous evaluation and delivery of works will be published on the virtual campus of the subject and may be subject to change in response to possible incidents. It will always be reported through the virtual campus, which will be the communicationmechanism between teachers and students.
  • For written exam-type assessment activities, a place, date and time of revision will be indicated in which the student will be able to review the activity with the teacher. If the student does not show up for this review, this activity will not be reviewed later.
  • If a student finds that they are unable to attend an assessment activity (exam or practical assignment milestone), there is a “protocol for requesting the rescheduling of assessment activities” through which the student can make this request.
  • This course does not follow the "avaluació única" system.
  • Notwithstanding other disciplinary measures that are deemed appropriate, and in accordance with the current academic regulations, the irregularities committed by the student who can lead to a variation of the qualification of an act of self- evaluation. Therefore, plagiarizing, copying or letting copying the practice or any other evaluation activity will imply fail with a zero and can not be recovered in the same academic year. If this activity has a minimum associated mark, then the student won't pass the course.
  • In this course, the use of Artificial Intelligence (AI) technologies is not allowed in any of its phases, unless it is specified during the class. Any work that includes fragments generated with AI will be considered a lack of academic honesty and may lead to a partial or total penalty in the grade of the activity, or greater sanctions in serious cases.
