DETAILED INFORMATION

At the end of the semester, the student can choose between two methods of evaluation: OVERALL EVALUATION or FINAL EXAM.

OVERALL EVALUATION

This assessment method is organised according to the activities described in the previous table. The evaluation process consists of:

- The evaluation of the tasks defined in the Teaching Guide during the Teaching period.

- A final Written Exam during the Examination period.

The assessment aspects evaluated in both parts and their contribution to the final mark are summarized in the following table:

Marks obtained during the Teaching period (as a record of the continuous evaluation process) will be kept until the end of the academic year.

Written Exam

The students have to make a Written Exam that assesses the theoretical and operating aspects of the subject (S2 and S3) at the end of the semester (at the date established in the examination period). This final evaluation is made to assess the extent to which the students have acquired all the competences and learning outcomes established for those aspects. The weight of this exam is the 50% of each of the evaluated aspects (S2 and S3).

Final assessment

The students must obtain a mark higher or equal to 4 (out of 10) in S4 to keep this evaluation method (Laboratory or computer practical work). The students will pass the subject through this evaluation method by getting a mark higher or equal than 5.0 out of 10 in the overall result (continuous evaluation and written exam), but with the condition of obtaining a mark higher or equal to 4.0 in the Written Exam and in S4.

FINAL EXAM EVALUATION

This kind of evaluation is based in only one written exam that evaluates all the aspects of the subject, by assessing the students´ acquisition of all the competences and learning outcomes established in the subject. This exam will take place during the Examination period on a date established by the centre. The final exam is weighted in the following way:

- Attendance and participation (S1), theoretical concepts (S2) and Exercises, problems and study cases (S3): 70%.

- Laboratory and computer practical work (S4): 30%.

In order to pass the subject, the student must have marks higher or equal to 5.0 out of 10 at each part of the final exam.

The students who have already fulfil the requirements of aspect S4 (Laboratory or computer practical work) through the OVERALL EVALUATION, by obtaining a mark higher or equal to 5.0 out of 10 do not have to make this part in the FINAL EXAM evaluation.

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

Using this approach, the following competences will be evaluated:: CB2, CB3, CB4, CB5, CG4, CG9, ST1, ST2 and ST3

Obtaining a positive evaluation indicates that the student has reached the following learning results of the module: 1, 2, 3, 4, 5, 6, 9, 14, 15, 16, 21 and 22.

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.

Any books, notes, documentation, or equipment allowed for the Final Exam and the partial exams of the overall evaluation have to be approved by the lecturer.

Teaching methodology and learning activities

Changes in skills and / or results

-

Changes in theoretical content

-

Changes in practical content

For 50% attendance, it is planned to carry out the practices on a rotating basis and substitute activities that allow said rotation, consisting mainly of carrying out software-type practices, preparation of subsequent hardware practices, analysis of hardware practices already carried out, and problem solving and case studies.

Schedule

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

Evaluation system

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

As a summary, the following tables are added, detailing the weight and format of the final test in Global Assessment:

Ordinary call

Extraordinary call

Resources

Expository classes in large groups or practice groups at 50%

In the case of 50% attendance, the following resources will need to be used: 

Technical means in the classroom:

- Videoconference infrastructure in the classroom or laboratory consisting of a video and audio capture system for use in a videoconference system or virtual classroom such as Google Meet or BigBlueButton.

Individual media (students in non-face-to-face format)

- PC equipment or similar.

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

 Common means (teachers and students):

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

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

Expository lectures in large group or practice groups at 100%

Given that the attendance in the Classes in practice groups is 100%, no exceptional resources are foreseen for them.

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:

- 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.

- 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 video conference 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 video conference 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 video conference 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.

- Before the maximum time indicated in the statement of the exam, each student will send the photographs, compressed in .zip 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 video conference 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. This video conference will be recorded to ensure the quality of the assessment. Unless approved by the responsible of the subject, each student will have the camera and microphone active during the videoconference.

- The exam grade will correspond to the result of correcting the non-invalidated questions of the written exam.

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 resources (teachers and students):

- PC equipment or similar.

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

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

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