| THE AIM OF THIS COURSE IS TO MAKE STUDENTS FAMILIAR WITH THE MATHEMATICAL LANGUAGE, THE ABSTRACT FORMULATION OF A PROBLEM AND WITH THE STRICT REASONING. WE WILL STUDY ALGEBRAIC STRUCTURES AND, IN PARTICULAR, GROUPS, RINGS AND VECTOR SPACES. 1. KNOWLEDGE AND UNDERSTANDING: THIS COURSE WILL PROVIDE AN INTRODUCTION TO THE SET THEORY, AND TO THE GENERAL THEORY OF ALGEBRAIC STRUCTURES, WITH EMPHASYS ON PROPERTIES OF GROUPS, RINGS AND VECTOR SPACES. 2. APPLYING KNOWLEDGE AND UNDERSTANDING: COURSE AIM IS ALSO TO ENABLE STUDENTS TO IDENTIFY FINITE AND INFINITE SETS OF ANY CARDINALITY, AND TO USE ALGEBRAIC STRUCTURES LIKE GROUPS, RINGS AND VECTOR SPACES. THE COURSE WILL TEND TO ENCOURAGE THE STUDENT'S ABILITY TO EXPOSE THE ACQUIRED KNOWLEDGE CLEARLY AND RIGOROUSLY. ANOTHER GOAL OF THIS COURSE IS HABITING THE STUDENT TO FORMULATE PROBLEMS AND TO REASON STRICTLY. THE STUDENT MUST BE ABLE TO ENCOUNTER DEFINITIONS, PROBLEMS AND THEOREMS REGARDING THE CONTENT OF THE TEACHING IN A CORRECT AND STRICT WAY. IT MUST ALSO BE ABLE TO SOLVE EXERCISES. |

| Teaching Methods | |
|---|---|
| THE COURSE INCLUDES 112 HOURS OF CLASSROOM TEACHING, DIVIDED IN TWO MODULES. FOR EACH MODULE THERE ARE 32 HOURS OF LESSONS AND 24 HOURS OF PRACTICE. COURSE ATTENDANCE IS STRONGLY RECOMMENDED EVEN IF NOT MANDATORY. THEORETICAL LESSONS WILL BE CONSTANTLY ALTERNATED WITH HOURS OF PRACTICE, DURING WHICH EXAMPLES AND EXERCISES WILL BE PRESENTED THAT ILLUSTRATE METHODS AND CONTEXTS OF USE OF WHAT EXPLAINED. |
| Verification of learning | |
|---|---|
| THE AIM OF THE EXAMINATION IS TO EVALUATE THE FAMILIARITY OF THE STUDENT WITH THE MATHEMATICAL LANGUAGE, THE ABSTRACT FORMULATION OF A PROBLEM AND WITH THE STRICT REASONING. FOR BOTH MODULES, STUDENT HAVE TO PASS A WRITTEN TEST AND AN ORAL INTERVIEW. THE FIRST WRITTEN TEST, WHICH CAN ALSO BE TAKEN AT THE END OF THE FIRST MODULE, INCLUDES EXERCISES ON SET THEORY, COMBINATORIAL CALCULUS, CONGRUENCES BETWEEN INTEGERS AND ORDER RELATIONS. IN CASE OF SATISFACTORY RESULTS OF THE TEST (WITH MINIMUM VOTE OF 18/30) THE STUDENT WILL TAKE THE FIRST ORAL INTERVIEW, BY WHICH THE KNOWLEDGE ACQUIRED ON THE TOPICS COVERED IN THE FIRST MODULE WILL BE ASSESSED. THE SECOND WRITTEN TEST INCLUDES EXERCISES ON GROUPS, RINGS AND VECTOR SPACES. IN CASE OF SATISFACTORY RESULTS OF THE TEST (WITH MINIMUM VOTE OF 18/30), THE STUDENT WILL TAKE A SECOND ORAL INTERVIEW BY WHICH THE KNOWLEDGE ACQUIRED ABOUT THE TOPICS COVERED IN THE SECOND MODULE WILL BE ASSESSED. IN THE FINAL EVALUATION (OUT OF 30), THE WRITTEN AND ORAL EXAMS RELATED TO THE TWO MODULES WILL COUNT IN AN EQUAL WAY. THE EXCELLENCE MAY BE REACHED BY STUDENTS WHO PROVE THEIR ABILITY TO APPLY THE ACQUIRED KNOWLEDGE AND SKILLS EVEN IN DIFFERENT CONTEXTS WITH RESPECT TO THOSE PROPOSED DURING THE LESSONS. |
