Are you going to teach all new vocabulary the same way???????
A- Passive vocabulary. It includes words that Ss need to understand when they encounter them during reading or listening i.e. when they listen to others saying them or when they come across them during reading. This sort of vocabulary is sometimes called 'receptive vocabulary since Ss use it for 'decoding' the message.
b- Active vocabulary. It refers to those words that Ss need not only to understand an oral or a written message but also to send an oral or a written message. Ss use active vocabulary items to produce messages. Hence it is sometimes called 'productive' vocabulary.
