Hundreds of amazing teachers post educational videos online every day. At Glean, weve structured and organized these videos, tagged them by educational standard, and wrapped them in interactive tools (like QA and practice exercises). Weve even built technology to pick the ideal teacher for the student based on his/her learning style and ability.
Our technology works by pairing students with the best lessons for them. Together our team of teachers have watched these lessons, studying and collecting a number of details on every lessonsetting, pace, teaching style, grade level, and more！
With Glean, students discover lessons by searching or browsing directly within a subject. Once a topic is chosen, Glean will quickly scan and analyze all the teachers within that topic to find those who match a students learning style closest. And if the video is not quite right for them, tell Glean and it gets better.
