Blendspace's power comes from the ease with which it is able to create flipped classroom modules. You literally drag and drop web elements onto the canvas and share. As a learning technology, Blendspace is extremely powerful because it teaches students "how to teach themselves" by familiarizing them with the place and time shifting of a flipped classroom. Moreover, it also emphasizes to students that classroom face-to-face time should be valued as it gives students valuable "practice" time to collaborate with each other and with subject matter experts. Once familiar with this methodology, students become more independent, effective, and discerning lifelong learners. While it offers premium subscription services, the free basic service is enough for educators to get started effectively. The vast library of flipped modules created by millions of educators can be freely adapted and used making Blendspace a truly effective learning technology.
