CHAPTER 5 :
 New Technology May Boost Artificial Arms
 Artificial arms are clunky and many amputation patients don't even bother to use them because they're difficult to control. But new research suggests that relocated nerves are allowing the brain to communicate directly with artificial arms. Director of the Neural Engineering Center for Artificial Limbs at the Rehabilitation Institute of Chicago. "In the simplest terms, it's a better tool.This will hopefully enable patients to do more of the everyday things that we all take for granted. The new artificial-arm technology is still in the development stages and it will be years before it's improved enough for general use and artificial arms remain very expensive.Then,learning to better connect the brain to the arm through nerves is a big advance.
Therefore, people with arm amputations typically control their artificial limbs by tensing the muscles in their upper body such as the biceps and triceps, to control cables. The devices just aren't good enough to meet their needs. In the new study. Surgically transferring the remaining nerves in the amputated arm to muscles in the chest and upper arm. The nerves then allow electrical signals to more easily reach the artificial arm with the help of a computer. The Luke Skywalker prosthetic hand idea that's been in science fiction will require a lot of technology to come together . The starting to see substantial advances in several of the pieces, but it's going to be a very long process to integrate these pieces into products for patients.

CHAPTER 6 :
 Fairsite first graders integrate technology into everyday learning.
Nowadays,Students learn by a variety of methods, with visual, audio, and tactile (touch) being the most common. A teacher often uses all three in combination. They may show an example on an overhead projector, while saying the steps needed, and the students follow the steps using hands-on materials. In today’s world of technology, teachers have an increased ability to reach their students in interactive ways that combine these different learning styles
The Smart Board works well with the different websites that are connected to our districts curriculum. For example, the new math curriculum has Internet accessible videos that demonstrate the steps needed to complete the math work. Most teachers have the ability to play those videos on their computer screens, or on televisions in their room. However, by using the Smart Board, which is nearly four feet square, every student can sit at their desk and still see. Hence, the students are all comfortable with how the touch screen works; they understand the iRespond is tracking their score, and they know can access the Internet through the SmartBoard. The students are not only learning their reading, writing and they are using technology in a way they believe helps them learn.
