|---|---|
| KNOWLEDGE AND UNDERSTANDING THIS COURSE WILL PROVIDE FUNDAMENTAL CONCEPTS OF THE DISCRETE STRUCTURES, WITH EMPHASYS ON APPLICATIONS. STUDENTS WILL GET USED TO FORMALIZE PROBLEMS PROPERLY AND TO THINK STRICTLY. APPLYING KNOWLEDGE AND UNDERSTANDING COURSE AIMS ALSO TO ENABLE STUDENTS TO SOLVE SIMPLE PROBLEMS AND EXERCISES APPLYING THE ACQUIRED THEORETICAL KNOWLEDGE. IN PARTICULAR, STUDENTS SHOULD BE ABLE TO PERFORM SET AND MATRICES OPERATIONS, TO FIND CORRESPONDENCES, APPLICATIONS, ORDINGS AND LATTICES, EQUIVALENCE RELATIONS, PARTITIONS, ALGEBRAIC STRUCTURES AND SUBSTRUCTURES, TO USE THE EUCLIDEAN ALGORITHM AND THE INDUCTION PRINCIPLE, TO SOLVE SYSTEMS OF LINEAR AND CONGRUENTIAL EQUATIONS, TO DETERMINE BASES AND DIMENSION OF A VECTOR SPACE, CARTESIAN AND PARAMETRIC EQUATIONS OF LINES AND PLANES IN THE EUCLIDEAN SPACE |

| Teaching Methods | |
|---|---|
| THIS COURSE CONSISTS ON THEORETICAL LESSONS AND EXERCITATIVE LESSONS. DURING THEORETICAL LESSONS STUDENTS LEARN BASIC NOTIONS AND SEVERAL TECHNIQUES TO PROVE RESULTS. DURING EXERCITATIVE LESSONS STUDENT LEARN HOW THE GAINED THEORETICAL KNOWLEDGE MAY BE USED TO SOLVE SIMPLE PROBLEMS. |
| Verification of learning | |
|---|---|
| THE LEVEL OF ACHIEVEMENT OF THE TEACHING OBJECTIVES IS CERTIFIED BY PASSING AN EXAM WITH OVER 30 POINTS EVALUATION. VERIFICATION INVOLVES A WRITTEN TEST AND ORAL EXAM THAT TAKE PLACE ON DIFFERENT CALENDARED DAYS. THE WRITTEN TEST, WHICH LASTS ABOUT 2 HOURS, CONSISTS OF 4 EXERCISES RELATING TO THE SUBJECTS OF THE COURSE. THE EXERCISES PROPOSED ARE SIMILAR TO THOSE RESOLVED DURING CLASS LESSONS. STUDENTS WHO GET A SCORE OF AT LEAST 18/30 ARE ADMITTED TO THE ORAL EXAM. THE ORAL EXAM CONSISTS OF A DISCUSSION ON THE TOPICS OF THE COURSE, AND IS PASSED IF THE STUDENT REACHES A MINIMUM OF 18/30. THE FINAL VOTE COMES FROM THE AVERAGE OF THE WRITTEN TEST AND ORAL EXAM. THE MINIMUM VOTE FOR PASSING THE EXAM IS 18/30. |
