Consider the car driving around a circular track. Once started, the driver maintains a speed of 45 m/h. Compare the driver's velocity with his acceleration in this case. A) The car is accelerating because it is changing direction but the velocity is constant. B) The car is traveling at a constant rate of speed so it is not accelerating and the velocity does not change. C) Acceleration is the change in velocity so the car is experiencing a change in velocity and it is accelerating. D) The car is traveling at a constant rate of speed so it is not accelerating but the velocity changes because the direction the car travels is constantly changing.

Schools are being forced to embrace computers. unlike their "digital immigrant" teachers, these students are "digital natives", born into a world where technology is an integral part of everyday life. almost every student has access to a multitude of computers, laptops and tablet devices. it would be crazy to assume an assignment would  notbe written on computer in this day and age.many schools now have a 1-to-1 computer policy, and many districts and states in the united states have mandated computers or ipads across the state for every student,  including los angeles, the second largest school district in the country.but the thing is, when they tried it in la, it wasn't the success they hoped for. that's because the tablets weren't used as much as they expected. rather, it appeared there was a gap between the digital native's love of technology and their use of it in the classroom.this conflicted relationship with computers is also underscored by much of the literature on education. it is also highlighted in professional development and conferences such as  edutech.
