Demonstration of the Syllabus Coherence with the Curricular Unit's Objectives:
The syllabus presented is consistent with the learning objectives of the curricular unit since there is a large convergence between the table of contents and the knowledge that the student is supposed to acquire in each of the program topics. The fundamental concepts of computer network organization are presented in the introductory chapter; physical and data link layers of the OSI model are presented in the two following chapters and, in the last chapter, local area networks are studied. The learning objectives are achieved by supplementing the theoretical concepts with concrete examples run in lab environment using simulators and network equipment.
Teaching Methodologies (Including Evaluation):
The transmission of knowledge in this syllabus will be with theoretical oriented lectures and practical classes in laboratory environment. The lectures present the fundamental concepts for understanding the items of the program. In practical classes students solve exercises eventually using physical or virtual equipment (in the context of simulators) where suitable. The final grade is calculated according to the following formula:
practical grade = 0,8 * (project) + 0,2 * worksheets
theoretical grade = (theoretical Test 1 + theoretical Test 2) / 2
final Grade = (2 * theoretical grade + Practical grade) / 3
Both the Practical and Theoretical grade have to be positive (> = 9.5).
If any of the components is not positive the curricular unit will not be completed and the positive component will be preserved according to the regulations.
Demonstration of the Coherence between the Teaching Methodologies and the Learning Outcomes:
The teaching/learning methodology applied in this curricular unit as well as its assessment is perfectly aligned with the objectives to be attained by the students at the end of the term. The theoretical concepts are presented, discussed, applied and evaluated in the context of lectures, which guarantees students a solid foundation to understand the challenges facing this area of knowledge. On the other hand, in the practical classes theoretical concepts are used to solve real problems using hardware and software tools. This combination guarantees student training and allow them to meet the scientific goals, essential to a good understanding of the area. The evaluation process including theoretical tests, practical worksheets and projects also guarantees a good balance between theory and practice. The ultimate goal is to train professionals specialized in state-of-the-art techniques and tools but also ensure their ability to follow future technology developments. In this curriculum unit the organization of layered communication systems, the fundamental concepts of data communications and the operation and protocols of local area networks are presented and evaluated in theoretical component. These concepts are then applied in the resolution of the worksheets and projects in the context of practical classes.
