Why is it important to learn about different technology tools when they are constantly changing? It is important to learn the basics before we delve into more advanced technologies. On p. 59 of our book, Morrison and Lowther write, "We begin by grouping digital tools into four categories: computers, mobile devices, peripherals, and data storage." The technologies within each of these tools are changing, but we need to learn how to use the basic fundamental tools to continue to move forward.
Most desktop computers do the same things as mobile devices, so why do teachers need to use both? Both the desktop and mobile devices have pros and cons, but are different in scope. Desktop computers are limited by immobility. They also are bulky and take up a lot of workspace. Mobile devices, such as digital recorders or e-book readers are much smaller. They are portable. But, they have a smaller battery life. They could be more easily dropped and broken. But, they serve some of the same functions that could be done on a desktop computer. So in deciding the best to use it would be best to first determine what your needs and budget are.
How can the cost of digital devices be justified when the functions they perform are often limited in number and scope? David Nagel, THE Journal (2011), writes an interesting article entitled, "Will Smart Phones Eliminate the Digital Divide?" Smart phones are one of the newest digital devices. The can replace a number of other devices, including a digital camera, gps, e-readers, email, and the list goes on. If this article is correct, and I agree with it, soon every child will have access to one. They are relatively inexpensive, portable, and replace most other devices. They don't break as easily as desktop computers and can do just about as much.
