1. Informal chats can be improved by warm up for more structured tasks like having role plays, mini presentations and oral commentaries.

2. For group discussion activities this can be improved by giving record and review. Here students record their discussions, they listen and watch for clarity, vocabulary and interaction. Or teachers can even base discussion on specific tasks and involve students in peer assessing.

3. Formal debates, teachers can use rubrics for peer assessment, to check for clarity, use of examples, rebuttal quality, and persuasiveness.

4. Role play situations, students can be assigned clear and contextual roles. Make each role realistic and linked to a clear communication purpose. An advantage of this activity, gives students a reason to speak and encourage context appropriate language.
