I saw these tweets (which I have put together in a Storify) from Dan Krutka today that demonstrated a new — at least, to me — neat idea on how to use photos in lesson.  He uses the famous image from Martin Luther King, Jr’s assassination, but it could be used with many other photos, including ones that are not well-known.  It could incorporate vocabulary acquisition and metacognition, especially with English Language Learners.  I’m definitely adding it to The Best Ways To Use Photos In Lessons.
