Learning activities and methodology
Four different teaching/learning activities will be used: theoretical lectures, problem-solving sessions, problem solving assignment and formative evaluation assessment tests. 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 group. PROBLEM SOLVING-SESSIONS AND PROBLEM-SOLVING ASSIGNMENTS(2,64 ECTS) For problem-solving sessions, students will be given problem statements in advance. Sometimes they will be required to meet in or off class time with fellow students to made solution easier. Problem solving will include common review of solutions and instructor-led correction. These should help ground knoledge and develop the ability to analyse and transmit information relevant to problem-solving. Common review is expected to improve opinion exchange between instructors and students. Each one of these sessions could inclue a shoft continuous assessment test about the topics studied during the week. PRACTICAL EXERCISES (0,86 ECTS) Two practcical exercises will be held a week past the end of units 2 and 4. CAD software tools will be used to simulate the behaviour of circuits whose analysis and synthesis have been studied in the previuous weeks. The student will be able to apply the studied topics to a simple engineering problem. 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. Collective tutoring sessions will be held after evaluative assessment sessions and their marks are made public to provide feedback to the group about the solution and assessment results.
