Diffen is a free collection of comparisons that people all over the world help write and maintain, similar to how people write and maintain wikis.
First, you enter two items or objects into the search bars:
Based on information on Wikipedia, Diffen takes those two objects and pops out a comparison of the two in chart format. For example, the image below shows a portion of the chart I received when I compared “Golden Retriever” and “Labrador Retriever”:
As you can see, the comparison is in depth and arranged into subcategories for easier comparison. The possibilities this comparison tool has in the classroom are endless, from compare and contrast papers to research for debates and argumentative essays. I myself am amazed by the vast amount of content Diffen can compare, and hope that you find this useful in your own classroom!
