programs, and promoting the effective use of technology as an
everyday tool for students.
There are three award categories:
 materials by grade groups (K4, 58, etc.)
 materials by content area (e.g., science and mathematics)
 materials that can be used in teacher education (tools
to be used by college faculty in teaching prospective
teachers)
New changes to the rules make it easier to participate, and
the deadline for 1999 entries has been extended to March 31.
