Model of Course Delivery and Faculty Workload
Understanding the effect of delivery format on faculty workload
depends on determining the time required for instruction as class enrollment
Assumptions of the model:
- The web class has grading support so instructor time is 15 min per student.
There is also a "maintenance" time of 1 teaching credit a semester to check links
and revise the web pages. In other words, the technology makes the student's 3-credit web
class a 4-credit class for the instructor.
- The essay class has 4 essay exams per semester. Each takes 20 minutes to write,
but grading takes one-half hour for each student for each test.
- The multiple choice class has 4 exams, each of which takes 8 hours to write.
However, it requires only 1 minute per student to grade each test using
machine-graded answer forms.
- A 3-credit web class takes 8 hours per week, so the maximum enrollment in
the web class, with grading support, should be 32 students for a 40-hour work week.
Since a 3-credit web class takes 4 credits to run, the professor
spends 10.7 hours per week on the class.
- The maximum enrollment in the 3-credit
lecture class should be 20 students for a 40-hour work week or 45 students for
a 56-hour work week.
- Many faculty members work longer than 40 hours and tolerate higher enrollments
with essay exams.
- The rise in hours per week using multiple choice exams is negligible, so very
high enrollments require only a marginal increase in faculty time. Multiple choice
exams which accurately assess student learning are assumed.
- The switch from an essay format to a multiple choice format occurs at
an enrollment of approximately 45 students.
