PPP is a paradigm or model used to describe typical stages of a presentation of new language. It means presentation, production and practice. The practice stage aims to provide opportunities for learners to use the target structure. Criticism of this paradigm argues that the freer 'practice' stage may not elicit the target language as it is designed to do, as in this meaning-based stage, students communicate with any language they can. It is not clear that forcing students to use certain structures to communicate in a practice activity will necessarily mean they will use these structures spontaneously later.
Example
The teacher presents and illustrates the communicative purpose of a new structure 'If I was you…' for advice. Then learners use prompts to complete sentences with the correct forms of the verbs. They practise by giving each other advice.
In the classroom
Despite current doubts about the usefulness of the practice stage in the PPP model, it is still a common framework to find in classes and in materials.
