the actual sample from?<br />
D.5 If the individuals in the actual sample are<br />
involved with an educational institution, what type<br />
of institution is it?<br />
102<br />
equal numbers of schools (~8% to 12%) within each<br />
of the nine classifications<br />
cells.<br />
School sample for science and social studies<br />
The final sample consisted of 103 elementary<br />
schools (82 % participation) and 58 middle schools<br />
(92% participation), for a total of 161 schools. Of<br />
the 103 elementary schools, 87 were from the<br />
initial 126 that were sampled, and of the 58 middle<br />
schools, 44 were from the initial 63 that were<br />
sampled. The remaining schools were from<br />
the list of alternate schools for each classification<br />
cell. This sample repre<strong>sen</strong>ted<br />
schools from 22 of 24 systems or counties in Maryland,<br />
and there were approximately<br />
equal numbers of schools (~9% to 13%) within each<br />
of the nine classification<br />
cells. In summary, during the 2 years, 251 schools<br />
participated in the<br />
study.<br />
Final sample for the study.<br />
As a result of questionnaire nonresponse, the<br />
linking of the questionnaire data to the mean scale<br />
scores for schools reduced the sample sizes. The<br />
final samples for this study consisted of 86 of 90<br />
schools for mathematics and language arts (reading<br />
and writing), 116 of 161 schools for science,<br />
and 111 of 161 schools for social studies. The samples<br />
for science and social<br />
studies were reduced disproportionately more than<br />
for the other content areas<br />
because both teacher and student questionnaire<br />
data were linked to science and social<br />
studies MSPAP performance data (listwise deletion).<br />
Less reduction in the<br />
sample would have occurred if only teacher questionnaire<br />
data were analyzed with<br />
the science and social studies performance data.<br />
However, student evidential variables<br />
could not have been examined.<br />
