Obviously, photos can be great educational tools with English Language Learners and with any students (see The Best Ways To Use Photos In Lessons). I post about many photo galleries, also called slideshows. To do it in a little more organized way, though, I recently began this weekly feature called “Photo Galleries Of The Week.” This post is a “round-up” of online slideshows I’m adding to various “The Best…” lists:

Astronomy Photographer of the Year 2011 shortlist – in pictures is from The Guardian. I’m adding it to The Best Images Taken In Space.

Sinkholes around the world is a Guardian slideshow.

Haven and Hell: The World’s Largest Refugee Camp. I’m adding it to The Best Sites For Learning About World Refugee Day.

Dadaab: the largest refugee camp in the world — audio slideshow is from The Guardian. I’m adding it to the same “The Best” list.

50 Most Extraordinary Churches of the World
