3.4 Speaking
 Presentations – signposts and stepping 
stones
1
1 There are many kinds of presentations, including: sales or product 
presentations; academic presentations about a project; a presentation at 
a job interview, etc.
2 The answer to this question will enable you to distinguish those students 
who have never given a presentation and those who have a lot of 
experience. It is useful to ask students who has given a presentation 
in 
English
; and who will give a presentation in the future. If students have 
never given a presentation, they can share their experiences of being part 
of the audience in a good and bad presentation.
3 A huge range of answers are possible here: prepare; research the 
audience fi rst; use notes; don’t read aloud; divide the presentation into 
3 / 4 / 5 parts; use prompt cards; do not speak too quietly; use graphics, 
etc. If presentations are very important for your group, collate the 
answers to question 3 on the board and encourage students to write 
them down.
