Teaching methods

The teaching activities include (1) the theoretical course (14 sessions of 2 hours each), (2) the guided exercises (16 sessions of 2 hours each), (3) a practical laboratory work (4 sessions of 2 hours each), (4) the ReflexSciences tests (see below), (5) the tutorial, and (6) the workshops organized by the AccESST unit (optional). It is essential to have a simple scientific calculator for the supervised exercise sessions and the practical laboratory work.
The different subjects are presented in the theoretical course via slides and blackboard notes. The fundamental concepts are illustrated using applications from modern life, short films or animations, and experiments. The guided exercises play an essential role in the comprehension of the theoretical course and allow the application of the studied theoretical concepts to real problems. The list of problems to be solved during an exercise session and a list of additional problems appears on the LPHY1101 MoodleUCLouvain websitesite no later than one week prior to the exercise session. Preparation of the problems to be solved is crucial. Participation in the practical laboratory sessions is mandatory. Students are asked to read Section 1 (Introduction to measurement uncertainties) of the laboratory handbook and the associated slides, and to perform the related online test. This test is open to participation on Monday of S5 and closed on Wednesday of S8. A description of the tasks to be carried out in the laboratory together with an introductory video appear on the LPHY1101 MoodleUCLouvain website approximately one week prior to each session. It is essential that this description be read carefully, the video be watched and the online test be performed to access the session. A laboratory report must be written and submitted at the end of the session. This report is evaluated. Each week, a ReflexSciences test (short video and multiple-choice questions) is proposed on the LPHY1101 MoodleUCLouvain website. The time to answer this test is limited. The purpose is to measure the (fine) understanding of the subjects studied the previous week. Each test is corrected during the guided exercise session that follows. A tutorial, during which the students may ask their questions to the teaching team, is held several times during the semester. The best approach is to work consistently throughout the semester. In particular, it is essential that students regularly solve the exercises themselves, and do not simply read the solutions.

Evaluation methods

The test on measurement uncertainties, the entrance tests to laboratories and the laboratory reports count for 20% of the final mark. This part of the mark will be used for each session and cannot be updated. The exam during the January session (and the other sessions) is written, lasts three hours and counts for 80% of the final mark. If the score obtained in the ReflexSciences tests (see above) is greater than or equal to 10/20 (14/20), a bonus point (two bonus points) is (are) awarded, provided that the mark obtained at the exam is greater or equal to 8.5/20.
The exam includes various problems similar to those solved in the guided exercise sessions (one of these problems is taken from the list of problems proposed in the sessions) and some questions that aim to check that the concepts and developments presented during the theoretical course have well been mastered (comprehension questions, demonstrations, true or false with or without justification, multiple-choice questions or sentences to complete).
All the subjects addressed during the theoretical lessons and the guided exercise sessions must be known for the exam. However, the students have access to a form with the main formulas, which is posted on the LPHY1101 MoodleUCLouvain website.
It is essential to bring a simple scientific calculator to the exam.
The modalities mentioned above are valid whatever the exam session.
In case of force majeure, the modalities of teaching and examination will be reassessed according to the situation and the rules in force.

Online resources

The slides and the short films or animations projected during the theoretical course, the list of exercises to be solved, the supports for practical laboratory work, exam examples and other useful documents are made available to students on the MoodleUCLouvain website of LPHY1101.
