This Issue Brief uses data from the 2000-01 Teacher Follow-up Survey (TFS) to examine teacher views on the technology in their classrooms. Specifically, teachers reported which types of technology they considered essential for teaching and whether they felt such technology was sufficiently available in their classrooms. In 2000-01, technologies that allowed teachers to communicate with others or access resources outside the classroom (e-mail, the World Wide Web, and telephone) were among the most frequently cited by teachers as being "essential" for their teaching. Most teachers reported that they found their classroom technology to be "sufficiently available." However, teachers with relatively few computers in the classroom reported sufficient availability of technology less often than teachers with more computers.
