Here are some suggestions to ensure your kickoff meetings are successful.
Hold the meeting over Video Conference, and ask everyone to have their video on. Try joining a couple minutes ahead to ensure your audio works well.
Have everyone introduce themselves.
Everyone should have the project details in front of them.
The company representative should introduce the scope of the project the students will be working on, and the expected deliverables.
The students should ensure they're clear on what's being asked of them, and ask any preliminary questions they may have.
Everyone should confirm the milestone due dates, as well as due date of the final submission.
Clarify how often you'll be communicating, and through what channels. Set a date for a future check-in meeting.
One team member should document what you've agreed on, and follow up with this in writing.
