In the human brain, a great deal of synaptic pruning occurs in early childhood. This pruning appears to be:.
A. The unfortunate result of insufficiently stimulating home and school environments.
B. The result of the fact that the cortex is slowly taking over responsibility for functions that have previously been controlled by other parts of the brain.
C. Due to an imbalance of important nutrients, and especially to low levels of the B vitamins in many children's diets.
D. An adaptive process that allows children to deal more efficiently with their environment.

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.
