Google Search by Reading Level
I'm beginning to wonder if I couldn't do an entire year of Google tips! The ability to filter search results by reading level was apparently added in early December 2010.
Here are the description and directions from Google support:
Sometimes you may want to limit your search results to a specific reading level. For instance, a junior high school teacher looking for content for her students or a second-language learner might want web pages written at a basic reading level. A scientist searching for the latest findings from the experts may want to limit results to those at advanced reading levels. To limit your search results to a specific reading level, follow these steps:
1. On the search results page, click Advanced Search below the search box.
2. Next to "Reading level" within the "Need more tools" section, select your desired reading level (basic, intermediate, or advanced) or choose to show all results annotated with reading levels.
3. Click Advanced search at the bottom of the page.
4. At any time, you can click the X in the right corner of the blue bar beneath the search box to go back to seeing all results.
The image at right shows part of the results for a "solar eclipse" Google search with annotated results. Clicking on any of the three levels will limit the results displayed to those meeting the criteria for that level. You will notice, too, that the reading level is indicated for each entry.
A Google employee explains the method used to determine the reading level:
The feature is based primarily on statistical models we built with the help of teachers. We paid teachers to classify pages for different reading levels, and then took their classifications to build a statistical model. With this model, we can compare the words on any webpage with the words in the model to classify reading levels. We also use data from Google Scholar, since most of the articles in Scholar are advanced.
