The Evolution of Classroom Technology: The Journey from Pen to Keyboard Infographic
Education and technology has always been in perfect harmony. Right from the days when chalkboards were invented during the 18th century till the interactive whiteboards started revolutionizing classroom learning, when magic lanterns paved the way to overhead projectors, and came pencil and paper, education has gone hand-in-hand with technology. The Evolution of Classroom Technology: The Journey from Pen to Keyboard Infographic tracks the evolution of technology in classrooms; for it’s not just important to know where the future is heading to in education, the past also matters!
Ancient technology in classroom

- 1996: The internet, which was by then considered a computer network used mostly by NASA physicists and academics, slowly entered into homes and educational institutions by 1996.
- 1999: Technology in the classroom reached new heights with interactive whiteboards which blended handwritten notes with interactive technology in 1999. Earlier versions of these whiteboards were connected to desktop computers through wires, whilst the latest ones are compatible with smartphones and tablets.
- 2007: 2007-2010 was the age for smartphones and tablets. The concept of classroom slates got a revamp with iPads which is taking classroom education to new heights.
Classroom technology in the future
- Biometrics: Biometrics, the science that recognizes people on behavioral or physical qualities, is surely the answer to student disposition in the classroom and develop teaching materials accordingly.
- Wearable-glass: Wearable devices in education is the next big thing to watch out. Virtual reality headgears, wristbands, smart watches will take education to the next level.
- Multi-touch: Multi-touch surfaces like desks or workstations can work wonder for students to collaborate with their peers around the world. Videos, online resources and other virtual tools available in the single swipe of the desk.
