Desktop computers, laptops, and tablets will continue to be used in schools due to their ability to access digital documents and the internet. Touchscreen technology allows for more interactive lessons and will likely become more common. SMART boards are an interactive teaching tool that engages students and facilitates discussion. Overhead projectors are becoming obsolete as information can now be easily updated on SMART boards and computers rather than printed transparencies. However, printers and scanners will remain important for obtaining hard copies of documents and digitizing physical materials.
