Results of this study were intended to be practical.
Optimal class sizes from the perspective
of the instructor were thought to be helpful to
policymakers who are trying to establish classsize
limits for online courses. Limitations of
the study were inherent to the research method
employed (i.e., recruitment of participants,
availability and credibility of respondents, and
limitations of the instruments), and results are
likely to be applicable to online courses as
defined in the study. Future research is recommended
to examine class size and interaction
from the perspectives of administrators and of
students.
