Presentation sharing uses desktop sharing technology to allow a presenter to share their screen with remote viewers. The presenter can display a PowerPoint presentation, photos, videos or other content for a group to see. Unlike collaborative sharing where all participants can edit content, presentation sharing is one-directional from the presenter to the audience. The presenter sends an invitation with a link and access code for attendees to join the online presentation. Using presentation sharing in the classroom allows teachers to add a visual component to lessons to engage visual learners. Students can watch presentations during class and review them later to help learn and memorize lesson aspects.
