Students use computers at school for interactive learning, powerpoint presentations, and to promote digital education. Computers are used occasionally, like in computer class or for projects. Using computers makes lessons more interesting and interactive. Research is often done digitally, while projects are sometimes created as powerpoint presentations. Smart boards make lessons more demonstrative and engaging for students, but they are costly and may expose students to harmful rays. Mobile phones are generally not allowed at school due to distractions and potential discrimination.
