The engagement aspect of technology is another important benefit. All learners need stimulation and varied learning methods. Technology offers students the chance to "do" as they learn, using hands and minds. Clicking the mouse or typing words on the keyboard gives physical stimulation. Many online activities provide instant visual and/or verbal feedback with congratulations or corrections. Students whose instruction includes music videos are developing their listening skills. When maps, graphs, text or pictures are part of an online lesson, reading and study skills are exercised.
