Snapchat is probably the most popular social media app among those under 30. What distinguishes it from other such apps is that it allows users to add cartoon-like images and text to their photos and videos. While this playful interaction between users may seem like the antithesis of serious learning, Tara Martin (2017) found a way to channel student interest in sharing annotated images toward an educational purpose by creating what she calls a BookSnap. Instead of snapping selfies, a student makes a BookSnap by taking a photo of a passage from a book, article, or other source and adding images and text to interpret and reflect on what they read (Figure 1). These can be emotions, thoughts, or feelings provoked by their reading.
