Learning activities and methodology
Three different teaching/learning activities will be used: theoretical lectures, problem-solving sessions and lab sessions. ECTS credits include in all cases an allotment for personal work and team problem-solving work. THEORETICAL LECTURES (2,48 ECTS) Theoretical lectures will include the use of blackboard and slide material to illustrate main concepts in subject. The explanation of theoretical concepts will be complemented with exercises and problem solution sketches. These lectures will require personal initiative and research plus theoretical study: he/she might be asked to develop particular concepts or apply them to specific problem instances either individually or in the group. PROBLEM SOLVING-SESSIONS AND PROBLEM-SOLVING ASSIGNMENTS (2,64 ECTS) For problem-solving sessions, students will be given problem statements in advance. Problem solving will include common review of solutions and instructor-led correction. These should help ground knowledge and develop the ability to analyze and transmit information relevant to problem-solving. The common review is expected to improve opinion exchange between instructors and students. The last minutes of these classes could be spent taking a short assessment test on the content seen during the week. LABORATORY TESTS (0.86 ECTS) It is intended to carry out two "software" laboratory in computer classroom where the student can simulate the circuits that have been analyzed or designed in the theoretical sessions. With these simulations, students can evaluate the success of the analysis and design techniques learned in class. Individual tutoring sessions are intended to involve specific, clearly defined aspects. Appointments will be managed through the learning management system being used during the course. If required, collective tutoring sessions will be held to provide feedback to the group about the solution and assessment results.
