In this article, the authors share their experiences as art teacher educators using social media in innovative ways that stretch and strengthen modality in lesson design. Specifically, they explore their process of using the popular blog site Tumblr as a format to design what they have termed "tumbling lessons" with preservice art educators at their respective universities. This approach to teaching-learning lesson design was inspired by Tumblr's use of seven distinct modalities: text, photo, quote, link, chat, audio, and video. The authors believe this format offers "any" teacher a structure for engaging with multimodal lesson design. Working through the various Tumblr modalities prompts the development of dynamic, responsive lessons in the art classroom and beyond.
