Teaching method

Theoretical classes, once a week, lasting 2 hours. Exposition of theoretical material and application examples. Practical classes lasting 2 hours every 15 days, with experimental work and theoretical and practical classes lasting 1 hour every week for resolution of problems.

Evaluation method

Class Types
Solid State Physics classes will have 3 components with the following weekly teaching load:
# T Theoretical – 2 h
# Theoretical-practical TP – 1 h
# P Practical – 1 h (2 h of laboratory, on alternate weeks);
All classes will take place in person.
P classes are mandatory and exclusive to students who do not attend.
The tests and exams are scheduled to be in person.
Theoretical Component
1. The assessment of the theoretical component is carried out through tests or exams.
2. As part of the continuous assessment, 2 tests will be carried out throughout the semester, the grade for which will be rounded to tenths.
3. The T component (CT) grade is the arithmetic mean rounded to the nearest tenth of the grades obtained in the tests or the final exam grade.
4.1 Students who obtain a CT score equal to or higher than 10 points pass the theoretical component.
Theoretical-Practical Component
This component has no direct evaluation.
Practical Component
1. Practical (laboratory) classes will begin in the 2nd week of classes, and are exclusively intended for students who have never attended this CU or students who have lost attendance (for having obtained it more than two years ago).
2.In the first practical class of each shift, the following will be: a) presented in detail the assessment rules for this component; b) registrations for shifts confirmed in person; c) working groups were formed (2 students per group); d) special operating rules within the scope of the current pandemic situation.
3.1 Students who do not satisfy paragraph 2.b may have their registration for the practical shift canceled at CLIP.
4. Students who have had attendance for more than two years will no longer have attendance. To register for practical classes, you must contact the professor responsible for the laboratory classes by email, indicated in order of preference three practical shifts. Depending on availability, they will be enrolled in a shift.
5. Within the limits of available places, changes of shift may be accepted during the first week of practical classes. To do this, students must contact the professor responsible for the laboratory classes by email.
6. In laboratory classes, 5 laboratory projects will be carried out and a brief questionnaire about each project will be submitted at the end of the class; Students will be assessed on their performance, on questionnaires about each experimental activity and on a detailed report to be delivered at the end of the semester on one of the 5 projects carried out that will be indicated by the teacher.
7.1 The final grade for the CP practical component will be calculated using the arithmetic mean of the grade obtained in the reports, with the grade rounded to the nearest tenth.
Any missing reports will be averaged with a rating of 0 points.
8. If necessary and applicable, the teacher reserves the right to carry out an individual or group oral assessment.
9.1 Students who obtain a CP grade equal to or higher than 10 and who have been absent less than or equal to 1, pass the practical component.
Frequency
1. Students who pass the practical component are granted attendance at the curricular unit.
2. The attendance obtained in the last two academic years is valid for the current academic year.
3. The agendas indicating students with attendance obtained in previous years will be published at the beginning of the semester. It is the student''s responsibility to check their status.
Approval
1. Students who pass both the theoretical and practical components simultaneously pass the course unit.
Final Student Ranking
1. The final classification (CF) is the result of the following expression approximated to the units:
CF = CT × 0.7 + CP × 0.3

Grade Improvement
1. Students who wish to improve their grade must comply with the legal registration formalities for this purpose.
2. Students who have passed the course unit in the last two academic years may only improve their grade in the theoretical component.
3. In either of the two cases mentioned in the previous paragraph, the classifications of the other assessment component (CP) contribute in the manner provided for to the new final classification in the event of effective improvement.
4. The new final classification is obtained by following the formula mentioned above.
5. In other cases not covered by the previous numbers, the student will not improve his/her grade.
Additional Rules – Classroom Conduct
1. In order for everyone to benefit from the learning experience, students are required to respect the following rules of conduct in the classroom:
a) Punctuality: Students must be present in the classroom at the start time of class. Teachers will prevent entry to students who arrive more than 5 minutes late;
b) Preparing for classes and participating in discussions: Active participation requires students to prepare the material presented and discussed in class, and to contribute to the discussions;
c) Cell phones, during classes of all Solid State Physics components, unless otherwise instructed by the teacher, must remain switched off and stored until the end of the class.
d) The use of laptops and other electronic devices in classrooms is subject to teacher approval.
Additional Rules – Tests and Exams
1. Each test will essentially focus on all the material taught in the theoretical classes up to the theoretical class prior to the test.
2. The tests are held on the date, time and room previously announced in CLIP.
3.1 Students may only have with them during the assessment test:
a) Writing material;
b) Identification document with photo;
c) Scientific calculating machine, non-programmable and non-graphical.
4. During the tests, the use of electronic devices, such as calculators and cell phones, is not permitted (which must be turned off and cannot be placed on the tables where the test is being carried out).
5. It is not permitted to unstaple the pages of notebooks with the statements and solutions made by students in the test.
6. The test will be invalidated if paragraphs 3, 4 or 5 are not satisfied.
8.1 Students who commit fraud in an assessment test (Test or Exam) will have said test canceled and will automatically fail the subject in the current academic year.
