Students are complied to enroll in the FCT Moodle e-learning platform through which the course will be managed. The platform will contain the Learning Topics (LT) of classroom lectures contents and documents preparation of pactical activities ( PA). A visit to the PAs learning units is mandatory. The teaching- learning includes face moments and moments of e- Learning , including:
Online theoretical lectures
Online practical sessions
Preparation of classes asynchronous component
Two tests and a final exam on person or online
The methodology conforms generally a e-Learning philosophy and seeks to quantify the work of students allowing the application of the " Bologna paradigm.
Online theoretical lectures
The online lectures of two hours on Zoom platform are supported by presentations and include demonstrations conduction and problem solving. A constructivist pedagogical perspective is embraced.
Lessons-tests ( asynchronous component)
The contents of the theoretical classes comprise Learning Units (LU), which follow the recommended bibliography. Some Learning Units will have a mandatory multiple-choice self-assessment test lesson associated with them.
Online practical sessions
The experimental sessions, of 1 -2 hour, take place online. Students enroll in groups of 2-3 elements in one of four classes available, using the CLIP platform for up to 18-20 students per class. Schedule and distribution map of the work by groups, are detailed in the platform. Each group performs a set of practical activities from the following :
PA 1 – Image formation
PA 2 - Reflection and refraction: Mirrors lenses and diopters
PA 3 – Introduction do Ray Tracing Software: how to set a lens
PA 4 – Solving geometric optics issues with ray tracing software I: paraxial and seidel analysis; aberration plots (astigmatism, distortion &lateral colour)
PA 5 – Solving geometric optics issues : with ray tracing software II: ray fan related plots; setting up and analyzing tilts and decenters
PA 6 – Light interference
PA 7 – Diffraction by slits.
PA 8 – Diffraction grating and applications
TP- Thematic projects
Each group presents two integrated reports, of practical activities PA1 and PA2 and another of the practical activities PA6 to PA8, which are uploaded in the Moodle platform after the respective experimental session, take place. These activity reports will be all evaluated and the final mark attributed (CPA) will be average of the grades attained in each report. There may be an individual discussion with students about the activities planned for each session, as a result reports marks can reflect this issue. The thematic project activities will be carried out in the last 4 weeks of classes, the last one being dedicated to its presentation and discussion. The final classification of this evaluation element, CTP, will include the report of this activity and its presentation and discussion.
Preparation of practical classes
The practical online sessions have to be previously prepared by students using LUs designated Practical Activities (PAs) in asynchronous component (for example: AP1 –Image formation). The PAs define objectives for the proposed activities and help the student to explore contents and orientate the preparation of the practical activity. As searching through these documents, the student should consult all related topics (links), taking notes of statements or expressions, or making copies in order to build your memorandum to assist the practical activity.
Online Activities – (3 evaluation elements)
Pactical – Pratical grade (3 evaluation elements)
Theoretical - 2 tests (2 evaluation elements)
Note: The tests can be in person or online
The evaluation of the experimental component is based on weekly laboratorial sessions spread over 1-2 hours according with graduation course and the delivery reports of these activities.
- Required presence and execution of at least 4 practical activities including a project with this last one compulsory
- Compulsory delivery of two reports of practical activities PA1, PA2 and PA6, PA7 and PA8, plus an integrated report of one thematic project.
- The final practical mark, per student, for each activity work delivered, will be rounded up to tenth and will take into account the individual performance in the execution of the work during the class (prior preparation of the work by the student, participation and execution of the work, answers to questions asked by the teacher about the work in progress).
- If necessary and applicable the teacher reserves the right to do an oral assessment.
- The final classification of the practical component (PC) will be the weighted average of the grades of the individual obtained in the practical activities AP1, AP2, AP6, AP7 and AP8 (and of oral evaluation if applicable), PAC, and the grade obtained in the project TP, TPC, in the following proportion:
PC = 0.4.PAC + 0.6TPC
Obligation of score equal or higher than 9.5 to obtain frequency (rounded to the nearest tenth).
The evaluation of the theoretical-practical component results from the two tests, with 1,5 hours each booth performed over the semester.
There is no mandatory minimum score for each test, but there is the condition for the arithmetic average of the tests scores to be greater or equal than 9.5 for approval in theoretical-practical component (each test is rounded to the nearest tenth before calculating the average, the average is rounded to the nearest tenth for the calculation of the final grade).
The attendance to the course is acquired through the execution of all the online activities available and a minimum practical grade of 9.5.
- If the student doesn’t obtain attendance, he fails the course, regardless of the marks obtained in the theoretical component (test scores).
- It is necessary to obtain attendace to access the exam.
- The minimum exam grade to get approved is 9.5 (rounded to the nearest tenth)
- With attendance and approval in tests
- Final Grade = 60% average of the tests (rounded to the nearest tenth) + 40% practical (rounded to the nearest tenth)
- With frequency and approval in exam
→ Final Grade = 60% exam grade (rounded to the nearest tenth) + 40% frequency grade (rounded to the nearest tenth)
- The Minimum Score for Final Grade approval is 10 (rounded to the nearest unit)
-Grade above 16 values in any theoretical component requires defense in oral test
Students with previous frequency should contact the teacher to confirm the frequency grade to be considered this year.
