Who would love it: Teachers, students, and parents.

Why it's good: Teachers can use it to make the grading process easier, to assess student performance, or to complement their lesson plans. Students can engage with learning material in a variety of ways, and they can also participate in online discussions with their classmates or other learners around the world. By making classwork easily available and offering access to resources, learners, and educators around the world, Edmodo provides a comprehensive setting for the online education experience and ensures that students remain safe and focused.

Why it's relevant: Edmodo has more than 48 million users and continues to expand both nationally and internationally. Recently, the company announced a partnership with Cambridge and Oxford University Presses, both of which will put resources from their renowned collections online and develop content for schools in the U.K.
