Overall Prediction of Which Teachers Have Students Use Productivity
Software Frequently
Most of this paper has presented analyses of how secondary math, English,
science, and social studies teachers’ use of computers during class time
appears to be affected by the teacher’s general beliefs towards constructivist
teaching and how it is affected by the nature of the teacher’s students—attributed
class ability levels, school SES, and school level, middle- or high school.
However, early in the paper several other factors were also mentioned
as key to the frequency that a teacher used computers during class—access
to clusters of computers in the teacher’s own classroom, their orientation
towards their role (between an outward “professional” orientation and
an inward “private practice”), the amount of technical expertise a teacher
possesses about computers (including their use of computers to accomplish
their own professional tasks), whether their school provides periods of
classtime that are longer than usual (“block-scheduled”), and whether
they typically cover many topics or a smaller number in greater depth.
The final analysis presented here brings all of these other variables
in along with the variables of clientele characteristics and personal
educational philosophy and examines which combination of variables appear
to best predict extensive use of specific types of software by teachers
of specific secondary subjects. A total of 14 combinations of software
type and subject-matter were examined—selected on the basis of their overall
prominence in teaching in that subject and their plausible relationship
to a constructivist teaching practice. Social studies teachers were examined
in terms of their students’ use of email, presentation software (e.g.,
Powerpoint), multimedia authoring environments (e.g., Hyperstudio), the
World Wide Web, and spreadsheet and database software. English teachers
were examined on Powerpoint and Web use by students; science teachers,
on Powerpoint, Web, exploratory software, and spreadsheets; and math teachers,
on exploratory software, Web, and spreadsheets. Word processing was not
examined in this instance because of its common presence in most computer-using
teachers’ classroom practices.
Exhibit 22 provides the result of multiple regression analyses, using
the admittedly crude 4-point dependent variables on which each teacher
responded in terms of the frequency of their students’ use of each type
of software (no use, 1 or 2 occasions, 3 to 9 occasions, 10 or more occasions).
On average, the 9 independent variables explained roughly 14% to 19% of
the variation in these 14 specific combinations of software and subject-matter.
Typically, at least 3 predictor variables had standardized partial regression
coefficients above .10 and at least 1 was above .20 in all but two cases.

The strongest
predictor of frequent use of these types of software by academic secondary
teachers was their technical expertise and use of computers for professional
purposes. The second strongest predictor was the extent of professional
engagement by the teacher—involvement in informal leadership roles at
school and in more formal roles beyond the school. The third strongest
predictor was the number of computers in the teacher’s own classroom.
The teacher’s philosophy was the fourth strongest predictor. One could
argue that technical expertise mediates the effects of a teacher’s philosophy
in that more constructivist teachers may be more apt to become expert
users of computers. However, even with teacher computer expertise taken
out of the equations, both classroom computer density and teacher professional
engagement are stronger predictors of the teacher’s frequent orchestration
of student use of these productivity-oriented types of software.
Compared to these four teacher-specific predictors, student characteristics
were less powerful.[11] However, high ability and, more
strongly, high school-level SES, both characterize social studies students’
greater use of email, presentation, and multimedia authoring software
during class, net of other factors. Those English teachers aided by block
scheduling assign students to do more Web work and Powerpoint presentations.
But consistently, it was the teacher-specific variables—technical expertise,
access to classroom computers, professional engagement, and, to a lesser
extent, having a constructivist philosophy, that predicted their use of
these constructivist-compatible uses of computers during class.
[11]
Note, however, that these regression models were entirely linear ones,
whereas much of the bivariate analyses in this paper pointed to interaction
effects among student and school characteristics and often suggested that
contrasting situations often led to similar levels of computer use.
