Lumi Cards provides school communication system for teachers, students and parents, which was developed based on our belief that students achievements could be improved just by better communication of homeworks, quiz preparations and other announcements through online. Lumi Cards makes the communication among teachers, students and parents easier and manageable. This communication application enables many parents to pay close attention to their children’s daily works which will add up to make big differences at the end. Teachers can send homework assignments, announcements, flashcards, other information and quizzes. Students can view all announcements, flashcards, and take quizzes through this application. The application also supports Member-Link among parent and student accounts that enables monitoring of the student’s Lumi Cards activities and all announcements and messages to the student’s account.
