Bit off topic concerning Unit 7 but thought this might help you with your radio drama essays, this will also coming in handy with your scriptwriting work and also are just very important to know as creative media professionals - which you all are!
Here are three key theories relating to narrative and character development which is as I understand was your primary concern so I put together a very short description of each to help you get started!
Todorov:
Todorov stated that all films/programmes etc should begin with an 'equilibrium' (a state of calm), then an 'agent of disruption' come along and causes a disequilibrium (a period of distress). This problem should then be resolved by the protagonist and therefore causes a brand new equilibrium. This is narrative theory and can sometimes be classed as 'The Hollywood Narrative' as it is the most common.
Strauss:
Strauss suggested that the main focus in a narrative is conflict and he stated that this can be caused mainly by binary opposites clashing. A few examples of this are 'hell and heaven', 'good and bad', 'black and white' and 'fire and water', but these are often represented through actual characters.
Propp:
Vladimir Propp conducted a theory in the twentieth century about narrative and character representation. He stated that their are eight key characters and these are he hero, the villain, the donor, the dispatcher, the false hero, the helper, the princess and her father. A character can often have a few of these traits in a drama.
Hope this helps a bit!
