Comparison of and Difference Between any two things.

Diffen is a difference engine that lets you compare anything.

Diffen will compare two terms and instantly produce a table with similiarites and differences. Students can search geometric figures, presidents, countries, affected vs effected, and much more. This site utilizes higher order thinking skills, since comparison of attributes requires analysis. Examples and tips are also included. The information can be mailed, tweeted, embeded or added to Google +. "Cite this article:" is available for the students to use during their research. It is a great tool to link to a teacher page, as there is no log on required. For comparison results, and more tips, it is optional but teachers can create an account.
