Teaching Methodologies and Assessment Criteria The classes combine theory with practice. The teacher introduces the concepts, states and proves the fundamental results, provides examples and applications. The students are encouraged to participate in the classes, to interact with the teacher and colleagues and to work independently, by solving exercises, guided reading, problem formulation and problem solving.
The evaluation carried out during the teaching-learning process consists of two written tests, and 10 Maple T.A. homework assignments.
Language Portuguese. Tutorial support is available in English.
