Nowadays, art classes play an increasingly important role in schools in China. But there is still space to improve. Firstly, teachers can't teach every student in one class because there are so many students in the same class, which is inefficient and less interactive; Secondly, students' works are not easy to be preserved and quickly gets lost; Thirdly, teachers are ineffective in receiving, correcting and dispatching assignments; Fourthly, if students do not bring homework home, parents cannot directly understand the progress in the art of their kids. This project aims to improve the teaching efficiency of teachers and increase the interaction with students and parents, saving artwork as well.
