Teachers are usually good at accommodating. When I was much younger (Grade 7 or 8) I once asked a teacher about this and it was agreed that I could film my presentation and she would show it in class to ensure the class received the information I was presenting on. This was in the mid 90s, so using the libary's video editing tools/hardware, I added titles and effects (mostly old-school wipes and fades) to justify the video (on VHS) presentation instead of just presenting in class. I was actually more embarrassed to watch the video with the class than I think I would have been just to speak and stutter so I never tried this again.
