Recognise different types of information
Lectures are intended to transmit information in three different ways:
Lectures contain factual material given verbally or on board or screen.
Most lectures contain an element of conceptual integration of the material. Many lecturers concentrate on concepts, on the premise that knowledge of the bare facts can be gained from books.
Sources of further relevant material may also be given.
Facts and references can be noted down as they are presented, often in the same form.
Concepts require analysis and interpretation of the material which is generally difficult to describe adequately in narrative form, especially if there are complex relationships involved.
