>From the Lucas Educational Foundation newsletter:

In one of the largest school implementations to date,
District 230 in the Chicago suburb of Orland Park has
equipped its three high schools with 2,200 handheld
computers. According to English, biology, and social
studies teachers in the district, use of the handhelds
has increased student productivity and efficiency across
all disciplines. In just one example, Laura Ritchey had
her biology students use the handhelds to create an
"ecological footprint," a measurement of the human
impact on nature. Sidestepping the tradition of handing
out paper assignments, Ritchey "beamed" the assignments
to her students' handheld computers via an infrared ray.
The students then used their handhelds to collect field
data and instantly input the data into the school
computer for further analysis.
