RDiagram is a simple tool to create a complex database. The emphasis is being put on ’simple’ since it is easy to use for anyone. It does not mean overtime work for anyone. Generally, 45 minutes is too short for most students to understand the complexity of a material. Textbook explanations are often dry and have already been taught in other lessons. For these reasons, private tutors and parents are helpful as they can explain the same things from different perspectives, through different examples. It would be naive to think that most families have these opportunities. Typically, there is no chance of going to private lessons in such families where parents themselves cannot help to understand 7th grade Physics. Computers are present in every family, even in less wealthy homes. Moreover, if there is a computer, rDiagram is available to them, filled with knowledge created by students in a student language for students.
