Teaching methodologies

- Module of mechanical engineering
Seminars and study visits to companies with the execution of synthesis reports;
Practical activities to produce a small mechanical systems involving, assembly, measurement, graphing representation and elaboration of a technical descriptive;
- Module of technical drawing
Practical activities for the execution of various freehand drawings from physical models and graphical representations of various methods;
Laboratory classes for performing several drawings in CAD systems;
Elaboration of a final project in CAD.

Demonstration of the teaching methodologies coherence with the curricular unit's intended learning outcomes

- Module of mechanical engineering
Several thematic seminars and study visits to companies are held where it is transmitted to the students the main areas of the Mechanical Engineer activity and what its role in the society. The implementation of a mandatory report requires students to acquire skills of synthesis and writing.
Practical activities allow developing skills with handling equipment and mechanical measurement and preparation of technical descriptive.

- Module of technical drawing
In practical activities of technical drawing, in which students have to perform several freehand drawings, allow developing reading skills, interpretation and graphic representation of technical drawings.
The CAD laboratory classes and mandatory enforcement of a final project requires the student to develop skills in the area of CAD and looking for solutions to future progress in the area.

Assessment methodologies and evidences

The evaluation is continuous. Works will be evaluated in the classroom and outside the classroom. Whenever it is not possible for the student to carry out the work in class, he must execute them outside the class and hand them over to the teacher.

List of works to evaluate and minimum notes:

- Seminar module (15% of the final grade in IEM, minimum grade 9.5 val (extrapolated to 20 values)).

Synthesis report summarizing the presentations assisted. At least each student must attend at least 10 sessions (excluding the opening session). (8%)
Presentation of the project developed (7%)

- Technical drawing module (85% of final grade in IEM, minimum grade 9.5 val (extrapolated to 20 values)).


Freehand exercises performed during practical classes (35%)
CAD: Test15%
CAD Design: 35%
Works with evaluation Accept / Not accepted distributed throughout the classes and submitted in the moodle platform. Works not delivered or not accepted have a penalty of 0.5 val / work on the module note.



It is recommended that works be delivered the week following the class assignment. Each work has a certain limit to be delivered, as it appears in moodle. A single penalty of 3 val. is applyed to non-fulfillment of the delivery date. After the deadline of 05/02/2018 no more works are accepted for evaluation in the normal season.

All the works evaluated are identified in the moodle platform.

The works / project are subject to oral discussion.
