I was reviewing an edition of Dr. Barbara Honeycutt’s Lecture Breakers Weekly, where she wrote:

After an experiential activity, discussion, reading, or lecture, give students time to write the one idea they took away from the experience. What is their one takeaway? What’s the main idea they learned? What do they remember?

This can be written as a reflective blog post or journal entry, or students might post it on a discussion board so they can share their ideas with their colleagues. Or, they can create an audio clip (podcast), video, or drawing to explain their One Takeaway.

From DSC:
This made me think of tools like VoiceThread — where you can leave a voice/audio message, an audio/video-based message, a text-based entry/response, and/or attach other kinds of graphics and files.

That is, a multimedia-based exit ticket. It seems to me that this could work in online- as well as blended-based learning environments.
