Details the Fairfax County, Virginia elementary science program, a key feature of which is the use of self-contained kits and instructional materials. Shows how the curriculum has improved students' achievement tests scores and is beginning to be adapted for mathematics, computer, and music education. (SK)

Describes changes and effects of the Israeli paper-and-pencil matriculation examination in biology since first analysis in 1972.
