Boolify – Boolean Searching

http://www.boolify.org/

This is a visual, interactive site which is good for illustrating to younger and middle school students the value of using Boolean search techniques. It could also be used as an introduction for senior students for a lesson on searching online databases.

To use it, you drag and drop coloured puzzle pieces onto the board – green for your search terms, blue for ‘and’, red for ‘not’.  As each piece is placed on the board, the number of results is shown below, along with the list of results.  Students can easily watch the number of results decrease each time they place a new piece on the board, which effectively shows them the benefits of using multiple search terms and Boolean operators.

The site also has a couple of lesson outlines for teaching Boolean logic, as well as links to videos on YouTube and TeacherTube.
