Tables 1 and 2 show that the number of suburban districts is over-represented
in the USEIT sample, whereas the number of urban districts is underrepresented;
and the number of white students is over-represented, whereas
the number of students on free and reduced lunch is under-represented when
compared to Massachusetts’ districts. Note that USEIT researchers did not aim
to generalize findings from this study but intended to investigate which district-
and school-level supports translated to regular use of IT in the interested
21 districts. The USEIT district sample was a purposive sample designed to
respond to the needs of a group of school districts in Massachusetts. Generalization
of findings from the study discussed here is limited to schools with

studies conducted to date that includes multiple data sources collected
at different hierarchical levels (i.e., district, school, classroom, and student).
The USEIT study included surveys of district-level personnel, principals,
