The following guidelines reflect what the Department believes is good teaching practice. They are only guidelines and we would expect the amount of material issued on handouts to vary with the style of the lecturer and the nature of the module.

• Copies of complicated diagrams or equations should normally be issued, where copying down the figures and equations in long-hand would lead to a significant risk of errors in students' notes.
• Pre-prepared notes treating additional, largely non-examinable, material can be helpful to students. For example, these additional notes might explore longer or more complete derivations than can be treated in lectures or provide background reading. Such notes should not, however, be used to extend the amount of material beyond what can normally be taught during lectures. It should always be clear to students what is examinable.
