Web offers real time access to the entire web. Search results can be filtered by reading level and subject area. To achieve this real time filtering, Choosito! uses advanced natural language technology to analyze the content of each webpage. Choosito! evaluates the reading difficulty of each webpage (first elementary school grades to high school and above) and its thematic content (science, language arts, socials studies, etc). the Teachers' Library is a dynamic, ever growing library that contains sites added by educators.
