Exploros is a collaborative learning experience delivery platform for teachers and students.
The content is good but the digital classroom needs a lot of work. There are few options for control for teachers and the interface could be more intuitive and less clunky, and it should allow for better use of student data. Overall it is useful it terms of content but not very useful as a digital classroom tool.
