Integrated courses which the majority of medical schools have now implemented, integrate what was previously learnt at the pre-clinical and clinical stages, to provide a seamless course. Teaching methods can include problem-based learning (PBL) and practical clinical skills.
Integrated courses are the GMC's recommended approach to medicine; instead of teaching anatomy and physiology etc. as separate courses, the idea is to join them into systems (also known as the systems based approach) where you will take a bodily system, such as the circulatory system and consider the anatomy, physiology, biochemistry, pharmacology, pathology of it all at once.
The new integrated approach also encourages early patient contact and self-directed learning. Much of the teaching has a basis in lectures, supplemented with tutorials and your own self-directed work.
However, there have been many interpretations of how this new integrated approach can be implemented, one of the big 'different interpretations' was pioneered by Manchester and is what we refer to as Problem Based Learning (PBL).
There are subtle, theoretical differences between learning styles of integrated learning course provided at medical schools; Problem Based Learning (PBL), Enquiry Based Learning (EBL) and Case Based Learning (CBL), but in most cases the lines between each of these are significantly blurred.
