Dear Trainers,...

Letting trainees discover learning points should be encouraged in a training room. One obvious practical benefit is stronger knowledge retention.
Here is a sample of an inductive way to present aspects related to oral communication.

Give the participants two sets of dialog showing different interlocutors, setting, language choice but similar topic. Ask them to memorize the lines and then perform them in front of the class. After that, ask questions leading to aspects involved in oral communication, e.g:

1. Who are in the dialog?
2. What are their relationship?
3. How do you know?
4. Would you use the same language with different interlocutors?
5. What else makes you would change the language? Is it the setting?
6. Tell me what you think will happen to the dialog if they were conducted via telephone?
7. What can you conclude from the above the questions?

Happy trying :)
