Students directory is designed for educators to quickly browse all of their new students. It gives teachers "everybody in one place" experience, where they can easily access, search and sort their pupils.
To bring more fun and usefulness to the application, students directory has a self practice functionality indicated with a dice fab. It simply calls out a photo of a random student. The teacher guesses and reveals the name. Then self-evaluates herself - which is quite helpful for a person in a learning process. This feature could be a perfect choice during the school breaks.
