The phrase 'theoretical class' is correct and can be used in written English.
It is typically used to describe a course that emphasizes the study of scientific principles or concepts, and does not involve physically doing something. For example: I'm taking a theoretical class this semester that focuses on the principles of quantum mechanics.
The 1-min paper was not only highly marked (80%%), but was also demanded by students at the end of the theoretical class because they realised how much they had learnt.
The course provides 490 hours of theoretical class work and students are still required to produce a monograph equivalent to 200 hours work.
In 2012 the subject was renamed "Health, Wellbeing and Physical Education" and has been reduced from 3 to 2 hours a week for all pupils in all grades, with one of these classes delivered in a sports gym and another in a classroom setting as a theoretical class [ 3].
Theoretical classes and even old laboratory experiments are of no appeal to them.
Theoretical classes in technical university teaching provide background information while laboratory practices show practical ways of proceeding in real situations.
In addition to the theoretical classes, which cover the scientific fundamentals, the student participates in workshops on the theme of practice, reading and writing practices, seminars, debates and supervised internships.
The growing concern of teachers to improve their theoretical classes together with the revolution in content and methods brought about by the New Information Technologies combine to offer students a new more attractive, efficient and agreeable form of learning.
The proposed algorithms were empirically tested and compared by using various sets of differently sized test data: some theoretical classes of graphs with known optimal solutions and some special classes of graphs chosen from the literature for the k-minimum spanning tree and Roman domination problems.
In addition, the Swiss VET system has a strong apprenticeship tradition, founded on a "dual" structure that combines theoretical classes at school with practical experience at the workplace.
In this case, besides the written support for theoretical classes, weekly online self-correcting questionnaires (Fig. 3) were developed as a support to the continuous learning of theoretical concepts.
Theoretical classes were given in 5 lectures and 5 practical classes about the e-FAST procedure, including the following windows: pericardial window; hepatorenal and hepatodiaphragmatic interfaces; splenorenal and splenodiaphragmatic interfaces; suprapubic; pulmonary and vena cava evaluation.
