Search engines are tools designed to help users find relevant web pages by searching for keywords. They work by having huge databases of web page files that are assembled automatically. Some key search engines include Google, Yahoo, and Bing. Search engines can be used educationally to help students find resources for projects and papers. While they are useful for visual and interpersonal learners, auditory, musical, tactile, and intrapersonal learners may benefit less due to a lack of audio content or an individual focus. Overall, search engines have been important learning technologies for students and educators.
