An alternative to, or even follow on from writing assignments can be having students record video. There are many different versions of this, from having students record quick responses to asynchronous discussions, to having students create short documentary or educational videos.
Nowadays, students have access to digital cameras, either standalone, webcam (connected to PCs) or in phones. As such they can record video. Many have experience posting video to popular social media sites. Student videos can be a great way for students to present a topic.
A variation on student video can be screencast or slideshow videos. Here, students present a series of images or video clips, while providing a narration. They may not appear in the video, but instead try out being a documentary filmmaker.
It is possible to have students post video to open video hosting services like YouTube. In some cases this may be appropriate. For example, you may have student teams composing explainer videos for the general public, with the understanding, from the course outset, that student work will be public.
However, in may other cases you may wish to keep student video creations available only within your course. In that case, you can configure a special Panopto resource so your students can "hand in" video assignments to you. COLI even has available a tutorial you can drop into your course, that shows students how to upload their video to Panopto via a D2L dropbox.
Just as you can create video notes in D2L, so can students, at least within discussions. Like you, students are limited to three minutes in length, but that's ideal for discussions (versus more formal presentations.) If you need to, review the Video Note process here. This is something your students can quickly learn to do without the added steps of sourcing and learning a specialized video recording application.
Many of the discussion plans described previously can be adapted to have students record Video Notes.
Moreover, Video Notes can be an choice instead of a requirement. Remember that for learners, choices, however small, can be empowering. You may have the same prompt (discuss this topic, at this length...) but offer students the chance to either craft a written contribution, or record their thoughts via webcam. This gives students opportunities to select the medium without adding additional assessment burden for you.
You've scaffolded a composition assignment - an essay, research paper, report, proposal project - and just handed back drafts with lots of text feedback. How can you be sure they've read and really understand the feedback? Offer some extra credit if they record a Video Note back to you summarizing your feedback to them!
