Study Search is an Australian search engine specifically designed for students.
Here’s how it describes itself:
“studysearch.com.au is a customised Google search engine developed for Australian Primary and Secondary school students.
studysearch.com.au uses the power of Google’s search engine combined with a growing database of educational websites. When a search is done Google checks our database and gives those sites priority in the search results. The student is still doing a full Google search but the results are tuned to display sites that are more relevant.”
It has sections for both primary and secondary school students. It doesn’t have visual screenshots, but I have to say I was impressed with the accessibility of the sites that came up in my searches.
I’m adding it to my website under Search Engines.
