Many students understand a practical better than they can say it aloud. Smart viva preparation uses repeated oral frames, probable questions, and calm rehearsal.
Teach answer frames
Students answer better when they know how to begin: aim, principle, observation, inference, or precaution.
Oral confidence rises when sentence structure becomes familiar.
Practise short and often
Two-minute viva rounds across the term work better than last-minute marathon sessions.
Short oral practice normalises speaking chemistry clearly.
- Keep a rotating question list.
- Use peer viva in pairs.
- Correct language gently but precisely.
Practical takeaways for teachers
- Teach sentence frames for oral answers.
- Use short repeated viva practice through the term.
