[EX Q]: Article: In the near future,we may be using our eyes to operate our smart-phones and tablets,even when it comes to playing popular games like Fruit Ninja. The Gaze Group has been developing eye-controlled computer technology for nearly 20 years.But those devices have been firstly designed to help those with disabilities,and are very expensive. "After a while,we figured out that probably the best way is to go for a mass-market way," says Gaze's Sune Alstrup Johansen."where everybody would have this available." Johansen and some of his colleagues have formed a new company,the Eye Tribe,which is hoping to develop the technology on a mass commercial level. The technology works with the help of the computing device toward the user's face. After making sure of the user's eye movements,the technology is then able to easily find where a person's eyes are moving,and then allow the eyes to control a cursor . "Our software can then determine the location of the eyes and know where you're looking on the screen to make sure what you're looking at,"reads an explanation on the Eye Tribe site. There has been a gradual change toward hands-free technology in recent years, particularly in the gaming world.Recently Xbox released the Kinect device,which lets users control their Xbox and play certain games using only their hands,legs and voices. But still,most of these devices have been more of a _ than a practical way to use one's hands to control a mobile device.Johansen said a replaceable filter would be a cheap,convenient way for most consumers. And even as companies like The Eye Tribe work to create such a product for the average user, making the eye-controlled technology more accessible and less expensive will have similar benefits for physically disabled users.

[EX Q]: Article: Becoming a teacher is one of the best ways to make a difference in the life of a child and even older students. Here are some great scholarships and grant opportunities to get the ball rolling on your dreams of becoming a teacher. Straightforward Teacher Program This is one of the most popular and unique scholarships available for students working towards becoming teachers. The foundation offers their scholarships every three months as opposed to each year. During each payment, four students receive a $500 scholarship. Prezell Robinson Scholarship Program While this scholarship is available only to students in the state of North Carolina, it is so incredibly helpful that many students choose to study in the state for the only purpose of receiving it. It is offered to college students who come from low-income high schools or families that are interested in pursuing a long term career in education at any level. New York State Scholarship Program Officials in the state of New York founded this program to award students who want to give back to their community through their ability to teach. The catch for this scholarship is that the students must be pursuing a teaching career in mathematics or science at the secondary level. Also, because the program was designed to improve the education system in New York, the candidates must sign a service contract agreeing to work full time within the state for at least five years after graduation. Coca-Cola Scholarships You may have many opportunities for grants and scholarships through The Coca Cola Foundation. There is the Coca Cola Teaching Foundation that will provide free money for students pursuing an education in the teaching field. This is the most obvious for teachers, but do not be afraid to check out their other offers. Funds For Teachers Not all scholarships or grants are for students entering or already in college. The Funds for Teachers scholarships are for graduates who are already working in the field, but want to improve their possibilities, skills and education in an effort to increase their ability to teach the students that cross their path more effectively. Teachers in PreK through 12th grade are applicable no matter where they teach or what subject they specialize in.
Question: How many students get their scholarships each year according to the Straightforward Teacher Program ?

[EX Q]: Article: Dr. Paul Kelly, head of Monkeseaton Community High School in North Tyneside, said it would mean the end of sleeping in lessons before lunch, after experiments showed teenagers could have different body clocks from adults and younger children. Russell Foster, an Oxford professor of neuroscience , tested the memory of 200 Monkseaton pupils at 9 am and 2 pm using pairs of words, and discovered a 9% improvement in the afternoon. Students correctly identified 51% of word pairs in the latest session, compared with 42% in the morning. Tayler McCullough, 15, one of the test subjects, said the majority of students would welcome the extra hours in bed, "I'm extremely hard to get up in the morning. One or two people like to get to school early, but most of us would be up for going in later. I'm sure it would make a big difference to our learning ability." Kelly is _ that a change of school timetable will have a meaningful effect on exam performance. He wants his school's governors to approve his plan and put the new time-table in place before the opening of Monkseaton's new timetable in place before the opening of Monkseaton's new school building, the most technologically advanced in the country, in September. Kelly hopes his latest idea will be just as successful. "We have to be practical. But this proves that, by starting later, children's learning improves, as does their health." Foster said, "This is preliminary data, but what's exciting is that it matches more detailed studies carried out in Canada and the US. Teenagers get up late not because they are lazy but because they are biologically programmed to do so."
