How can the concept of open education appear as a collection of images?
Use your internet search schools to find openly-licensed images, or better yet, take your own photos, to collect at least 5 images that convey the idea of being an Open Educator. Then use an app such as Pic Collage or Insta Pic Frames to create a multiple image collage. Post your final image at a public UR: (e.g. DropBox, GoogleDrive, Flickr).
