How I Use It
My students and I have used this search engine in addition to school-purchased databases for research purposes (smaller text-based questions or larger inquiry tasks). The perk of this search engine is the credibility of the sources; however, like with all search engines, students must be taught how to use effectively and safely use a search engine.
As an educator, I think this branch of Google search engine is great. The credible, relevant sources gained through key word searches allows my students to perform better searches regarding some topics that sometimes 'open the floodgate' on other search engines. Sources must still be checked for reliability.
