LIST OF THEORETICAL EXERCISES

- Exercises Unit 1 and 2

- Exercises Unit 3

- Exercises Unit 4

The development of large group and small group lectures will be focused on promoting quality teaching by giving priority to activities that foster inclusive and equitable learning (Quality education, SDG-4).

A1. Lectures with large group of students

They are based on the explanation of the theory concepts, exercises and practical problems of the course.

In this activity, the following competences will be evaluated: CB6, CB7, CB8, CB9, CB10, CE1, CG4, CG5, CG6, CG7, CG8, CG9, CG10, CT1, CT2, CT3, CT4, CT5, CT6 and CT7. Obtaining a positive evaluation indicates that the student has reached the following learning results of the module: 13, 14, 15.

A2. Lectures with small groups

They are based on the explanation of the practical units in the lab including the execution by the students and resolution of problems in class.

In this activity, the following competences will be evaluated: CB6, CB7, CB8, CB9, CB10, CE1, CG4, CG5, CG6, CG7, CG8, CG9, CG10, CT1, CT2, CT3, CT4, CT5, CT6 and CT7. Obtaining a positive evaluation indicates that the student has reached the following learning results of the module: 13, 14, 15.

The use of electronic devices both in classes and exams is forbidden except that they are required for the right develoment of learning activities and always with the authorization of the lecturer.

Only those students who are entitled to online access according to the current regulations will be allowed.

Students with special educational needs should contact the Student Attention Service (Servicio de Atención y Ayudas al Estudiante) in order to receive the appropriate academic support

At the end of the term the students can choose between two assessment modalities:   CONTINUOUS ASSESSMENT   or  FINAL EXAM. In both assessment modalities, the use of electronic devices in classes and exams is forbidden except that they are required for the right develoment of learning activities and always with the authorization of the lecturer. 

Continuous Assessment

The Continuous Assessment modality will be carried out according to the outcomes of the activities planned in the syllabus and described in the section "Methodology and activities", in addition to those described in the section "Detailed description of the Continuous Assessment" that will be weighted by considering the aspects and percentages detailed in the above table. 

During the teaching period, it will be evaluated aspects S2 and S3 in a single exam including Unit 1 and Unit 2, while during the examination period it will be evaluated Unit 3 and Unit 4. The evaluation of Unit 3 and Unit 4, according to Continuous Assessment, will take place in the same date of the official exam of the subject established by the Centre.

Continuous Assessment evaluation will be only available during Ordinary call. Consequently, during Extraordinary call only Final Exam evaluation will be possible.

The S4 aspect will be assessed after the completion of each practical of the course according to the lecturer's decision. The date of such assessments will be set by the lecturer. The evaluation of each practice may be oral, handwritten or by means of computer.

To pass the subject, the student has to get a mark higher or equal than 5.0 out of 10 in the overall result of the evaluated aspects, as  long as the student has obtained a mark higher or equal than 4.0 out of 10 in each one of those assessed aspects (S2 and S3) and S4. In the case that S4 mark (obtained in the Continuous Assessment) or (S2 and S3) mark of the official exam is lower than 4.0 out of 10, the mark that will appear in the record of the subject will be the  minimum mark of the two previous ones, so   the student must follow the Final Exam modality.

Using this approach, the following competences will be evaluated: CB6, CB7, CB8, CB9, CB10, CE1, CG4, CG5, CG6, CG7, CG8, CG9, CG10, CT1, CT2, CT3, CT4, CT5, CT6 and CT7. Obtaining a positive evaluation indicates that the student has reached the following learning results of the module: 13, 14, 15.

Final Exam

In the FINAL EXAM modality, an exam will be held on the day set for the course within the exam period, which will cover all the course contents, ensuring that students have acquired the competences and learning outcomes established for the course. The two parts of this written exam are weighed as follows:

- Part 1: Attendance and participation, theoretical concepts and completion of study cases or exercises assignments (S1, S2, and S3): 70%.

- Part 2: Laboratory/computer practical work (S4): 30%.

The specific conditions, as well as the material and/or documentation that may be used in the Final Exam will be established by the lecturer.

In order to pass the subject, the student must have marks higher or equal to 5.0 out of 10 in each of the two parts.

Students who have passed the S4 aspect (laboratory/computer practical work) of the course, through CONTINUOUS ASSESSMENT, with a grade equal to or higher than 5.0 out of 10, will not have to take Part 2 corresponding to this aspect in the exam. The same grade obtained in the CONTINUOUS ASSESSMENT will be assigned to this part.

Those aspects successfully completed with a mark higher or equal to 5.0 will be considered passing during the academic year.

When S4 mark of the official exam or (S2 and S3) mark of the official exam is lower than 4.0 out of 10, the mark that will appear in the record of the subject will be the minimum mark of the two previous ones.

Using this approach, the following competences will be evaluated: CB6, CB7, CB8, CB9, CB10, CE1, CG4, CG5, CG6, CG7, CG8, CG9, CG10, CT1, CT2, CT3, CT4, CT5, CT6 and CT7. Obtaining a positive evaluation indicates that the student has reached the following learning results of the module: 13, 14, 15.

DETAILED DESCRIPTION OF THE CONTINUOUS EVALUATION

For those students whose assessment is carried out using continuous evaluation, it will be based on the monitoring and implementation of the activities in the four categories detailed in the table below, that make up the total of the evaluable elements of the subject:  

S1: Attendance, 10%.  

S2: Theoretical concepts of subject, 30%.  

S3: Exercises, problems and study cases, 30%.  

S4: Lab/Computer Practices, 30%.

Each of these blocks will be detailed as follows. In each block, the following competences will be evaluated: CB6, CB7, CB8, CB9, CB10, CE1, CG4, CG5, CG6, CG7, CG8, CG9, CG10, CT1, CT2, CT3, CT4, CT5, CT6 and CT7. Obtaining a positive evaluation indicates that the student has reached the following learning results of the module: 13, 14, 15.

S1. Attendance (10%)  
This aspect will be assessed in terms of attendance at large group and small group classes. Failure to collaborate in maintaining a good working environment in the classroom and obstructing the work of the lecturer in any session will result in an attendance mark equals 0.  
If there are activities organized by the Telecommunication Engineering department and the attendance has been recommended by the lecturer responsible for the subject, then 75% of the S1 mark will be due to the attendance in class and the remaining 25% will be due to the attendance at all the above activities organized by the Telecommunication Engineering Department and have been recommended by the lecturer responsible of the subject. If there is more than one organized activity, then each activity will have an equal weight within 25% of the S1 mark.

S2. Theoretical concepts S2 (30%)  
The evaluation of the theoretical concepts will be carried out by means of evaluation tests or exercises proposed in class by the lecturer. Each test will be evaluated separately and the student will be able to obtain a mark between 0 and 10 points. The weight of each test in the final evaluation is equal. Thus, a single test will be performed considering together Unit 1 and Unit 2 with a weight of 100%. The mark to be obtained will be between 0 and 10, extrapolating correspondingly to the range between 0% and 30%. This value coincides with the total value of the assessment of this section. 

S3. Exercises, problems and study cases S3 (30%)  
The evaluation of exercises will be carried out through evaluation tests or exercises proposed in class by the lecturer. Each test will be evaluated separately and the student will be able to obtain a mark between 0 and 10 points. The weight of each test in the final evaluation is equal. Thus, a single test will be performed considering together Unit 1 and Unit 2 with a weight of 100%. The mark obtained will be between 0 and 10 points, extrapolating correspondingly to the range between 0% and 30%. This value coincides with the total value of the assessment of this section. 

S4. Laboratory or computer practice work S4 (30%)  
The evaluation of the practical concepts will be carried out by means of evaluation tests or exercises proposed in class by the lecturer. Each test will be evaluated separately and the student will be able to obtain a mark between 0 and 10 points. The weight of each test in the final assesment is equal. Thus, two tests will be carried out: i) First test: MATLAB seminar and Practice 1; ii) Second test: Practice 2 and Practice 3; with weights of 50%. The mark to be obtained will be between 0 and 10 points, extrapolating correspondingly to the range between 0% and 30%.

Teaching methodology and learning activities 

Schedule

The schedule can vary mainly due to the change from multi-modal scenario to the online one.

Evaluation system (Ordinary and Extraordinary call)

There are no changes in the evaluation format (weights of each section) or in what is specified in the detailed evaluation.

Since the evaluation of the subject is continuous, there will only be an exam in the event that the student opts for the Single Test Evaluation, which is summarized in the following tables:

Resources

Given that the attendance in the large group lectures and in the classes in practice groups is 100%, no exceptional resources are foreseen for them.

In the multimodal and / or non-face-to-face scenario, when appropriate, the teaching staff involved in teaching, reserves the right not to give consent for the capture, publication, retransmission or reproduction of their speech, image, voice and explanations, in the exercise of his teaching functions, in the field of the University of Jaén.

Teaching methodology and learning activities 

Schedule

The schedule can vary mainly due to the change from multimodal scenario to the online one.

Evaluation system (Ordinary and Extraordinary call)

There are no changes in the evaluation format with respect to the 100% in person class mode. However, the tests of continuous evaluation of the aspects S2, S3 and S4 of the 100% in-person and Multimodal modalities that take place during the teaching period become a synchronous online exams in the online modality.

The synchronous online exam, both theory-problem (S2-S3) and practice (S4), will be organized in a written assessment by video  conference. The synchronous online exam will be carried out by means of the following actions, arranged here in temporal order:

- It will be organized at the same day and time for all students.

- At the latest one week before the date of the exam, and following the instructions of the responsible person for the subject, the students must inform the teacher of their intention to take the synchronous online exam. If a student does not communicate his/her intention to take the exam, then his/her personal interview by videconference will be in the following days of the date of the exam.

- Before the day of the exam, the responsible of the subject will communicate to each student the exact time of the validation interview of the exam, and the link to access the videoconference for both the part related to the problem-theory exam (S2-S3) and the practice exam (S4). Those  students that do not confirm their assistance may be cited to the validation interview in the next days of the official date.

- In the day and time of the schedule established for the official exam of the subject, the first part of the videoconference exam will be started. At that time, the  responsible of the subject will distribute by electronic means the statement of the exam to each student. The exam sent to each student may be different in content (questions or input data) but of similar requirement. The objective is, in cases where it is possible, to randomly distribute exams among the students. This videoconference will be recorded to check the identity of each student. Unless approved by the responsible of the subject, each student will maintain the camera and microphone active during the videoconference. If the student is absent from the videoconference, this may be a reason for expulsion, which will not happen due to mere technical problems.

- Each student will send the photographs, in .zip of pdf format, of the solutions he/she has made in relation to the exam received. The student is solely responsible for ensuring the quality of the photos of solutions. If a photograph with the solutions does not have enough quality to know perfectly what the student has answered in his/her answer, this question will not be corrected in the assessment.

- The second part of the exam will consist of a videoconference interview with each student to validate the contents delivered, at the time indicated, with a maximum of 10 minutes. The purpose of these interviews is to corroborate the authorship of the answers given in the first part by means of complementary questions on the assessment test. If a student does not correctly answer a question in the second  part, then the question in the first part with which it is linked will be invalidated. In this manner, the exam grade will correspond to the result of correcting the non-invalidated questions of the written exam. This videoconference will be recorded to ensure the quality of the assessment.

- If due to technical problems of any student his/her videoconference cannot be carried out normally, an examination of incidents will be considered in the synchronous online mode.

Resources

Since all the teaching, either in the exposition classes in large groups or in the classes in practice groups, be taught online, the following resources will need to be used:

Common telematic means (teachers and students):

- PC or similar equipment and Internet connection with sufficient bandwidth to correctly receive both the audio as well as video broadcast. 

- Videoconference system or virtual classroom, such as Google Meet or BigBlueButton.

- Use of interactive tools: screen sharing to use comments as a whiteboard virtual in PDF presentations. 

- Use of the teaching platform of the University of Jaén: messaging, forums, tasks, activities and media of evaluation. 

- Remote access to the equipment in the assigned laboratory to be able to use the practice software in case required.

In the multimodal and / or non-face-to-face scenario, when appropriate, the teaching staff involved in teaching, reserves the right not to give consent for the capture, publication, retransmission or reproduction of their speech, image, voice and explanations of chair, in the exercise of his teaching functions, in the field of the University of Jaén.
