What happens in the viva-voce?

The course's sequence: the paper's presentation to the class → the teacher's-and-peers' comments, feedback and suggestions → the final paper (feedback incorporated) → the viva-voce.The presentation's preparation:1. The time discipline — the convener's slot (usually 10–15 minutes); the rehearsal; the timing.2. The structure's distillation — the problem, the questions, the method, the findings, the proposal (the paper's whole in the frame).3. The slides' craft — the points, not the paragraphs; the case's citation on the slide; the visual where it aids (the structure's diagram); the readable font's discipline.4. The delivery — the notes-not-reading; the audience's eye; the pace; the technical terms' introduction; the timing's respect.
