	Teaching Methods
	TEACHING INCLUDES THEORETICAL LECTURES AND CLASSROOM EXERCISES. THE THEORETICAL LESSONS PRESENT THE COURSE CONTENT ACCORDING TO THE REPRESENTATION-TECHNICAL COMMUNICATION PATH. IN THE CLASSROOM EXERCISES, PRACTICAL CASES OF TECHNICAL REPRESENTATION ARE PRESENTED AND DISCUSSED. STUDENTS ARE ALSO ASKED TO CREATE THEM FROM SCRATCH. DURING THE EXERCISES, THERE ARE MOMENTS DEDICATED TO ANALYZING THE STUDENTS' WORK, PROVIDING PERSONALIZED EXPLANATIONS, AND OFFERING GENERAL CLARIFICATIONS OF THE DIFFICULTIES ENCOUNTERED. STUDENTS WORK BY HAND AND WITH THE AUTOCAD SOFTWARE IN A 2D ENVIRONMENT.

	Verification of learning
	THE EVALUATION OF THE ACHIEVEMENT OF THE PREDEFINED OBJECTIVES WILL TAKE PLACE THROUGH A PRACTICAL TEST AND AN ORAL INTERVIEW. THE PRACTICAL TEST WILL CONSIST OF MANUAL EXERCISES IN GRAPHIC CONSTRUCTION OF GEOMETRIC ELEMENTS AND CREATION OF A STANDARDIZED TECHNICAL DRAWING OF A MECHANICAL ELEMENT USING SOFTWARE. THERE WILL ALSO BE AN EXERCISE IN CALCULATING TOLERANCES. THE PRACTICAL TEST WILL BE CONSIDERED PASSED IF EACH EXERCISE IS COMPLETED SUFFICIENTLY. THE PRACTICAL TEST EVALUATION DEPENDS ON THE CORRECTNESS OF THE GRAPHICAL CONSTRUCTION EXERCISE, THE ACCURACY OF THE TOLERANCE CALCULATION, AND THE CORRECTNESS, COMPLETENESS, AND CLARITY OF THE TECHNICAL DRAWING. THE ORAL EXAM AIMS TO VERIFY KNOWLEDGE OF THE PRINCIPLES UNDERPINNING ORTHOGRAPHIC AND ASSONOMETRIC PROJECTIONS, THE RULES OF DRAWING, AND TOLERANCE THEORY CONCEPTS. THE FINAL GRADE IS USUALLY THE AVERAGE OF THE WRITTEN AND ORAL EXAMS. THE FINAL GRADE, EXPRESSED IN THIRTIETHS WITH POSSIBLE HONORS, DEPENDS ON THE OVERALL MATURITY DEMONSTRATED IN RELATION TO THE COURSE CONTENT. HONORS ARE AWARDED WHEN THE CANDIDATE DEMONSTRATES SIGNIFICANT MASTERY OF THE THEORETICAL CONTENT AND HIGH-LEVEL PRACTICAL TECHNICAL REPRESENTATION SKILLS.
