Presenting in a group presents unique challenges for many students.
Consider each group member's role in creating and delivering the presentation. Does everyone need to talk, or can some group members spend their time creating slides or completing other relevant tasks?
Pay special attention to transitions between people. This is especially important when group members have different presentation styles (i.e. one is very quiet and calm, and the next group member is loud and outgoing).
It’s also helpful to consider in advance who will answer which questions. This makes you seem more prepared on the day of the presentation.
Be sure to practice as a group before you present.
