Roslyn Hing School on long Island recently started a pilot program using iPads in some classrooms.
A growing number of schools across the U.S.are multimedia,history through gamse and math with step-by -step animation(动画）of complex problems.
As part of a pilot program,Roslyn High School handed out 47 iPads on Dec.20,2010 to the students and teachers in two humanities(人文学科）classes. The school district hopes to provide iPads eventually to all 1,100 of its students.
The iPads are to be used in class and at hom during the school year to replace texbooks,allow students to correspond with teachers and tum in papers and homework tasks,and preserve a rocord of student work in digital files.
“It allows us to extend the classes beyond these four walls.”said larry Reiff,an English teacher at Roslyn who now posts all his course mateials online.
But educators are still divided over whether practices to give every student a laptop have made a difference academically.
“Thre is very little evidence that kids learn more,faster of better by using these machines,”said Larry Cuban,a retried professor of eduction at Staford University.“IPads are excellent tools to attract kids,but then the fieshness wears off and you eget int hard-core problems of teaching and learning.”
But school leaders say the iPad is not just a cool new toy but rather a powerful and multifunctional tool with a number of applications,including thousands with educational uses.
“If there isn't an application that does something I need ,there will be sooner or later,”said Mr.Reiff,who said he now used an application that includes all of Shakespare's plays.

Ants have a reputation for strength,organization and teamwork.But researchers have now discovered that a key secret to the success of ants is their ability to identify the importance of age in the work place.
A study of Gentral American leaf-cutter ants has shown that the younger and stronger members are give the toughest job of cutting therough the leaves they harvest.Their sharp youn teeth do this job effectively,but as they get older their teeth become relatively worn and blunt.
But rather than being retired or abandoned by the group,the ageing ants are given a new role more suyted to their physical abilities.They become carriers and teansport the leaves back to the kingdom where they are harvested for food.
The findings by researchers from the University of Oregon and the Oregong State University support previous research showin the survival of a leaf-cutter kingdom depends on the efficiency(效率）of is workers.
“Cuting leaves is hard work,”said Dr.Robert Schofield,who led the research team.“Much of the cutting is done with a V-shaped blade(刀片）between teeth on their jaws.This blade starts out as sharp as the sharpest razor blade that humans have developed.”But over rime the teeth become blunter and the cutting job slows down.The team estimated that,because of this age-related wear,a colony(蚁群)spent twice the energy cutting leaves than it would if all the ants had sharp blades.Its findings support the idea that wear and break can be significant problems for insects as well as largre animals.
Like humans,leaf-cuttre ant recognize that older members of the group can still make a worhwhile contribution to society.“This study shows an advantage of social living that we are familiar with,”said Dr.Schofield.
