For Class A, the student mode age was 20 years old (32.9%, n=23). There were

20 students (28.6%) who reported their age as 21years of age and 10 students (14.3%)

who were 19 years of age. Almost half of Class A were juniors (48.6%, n=34), while

30% (n=21) were seniors and 18.6% (n=13) were sophomores. There were only two

(2.9%) freshman enrolled in the class that participated in this study.

 Students were asked how many courses they had taken in the subject area similar

to Class A. Respondents reported that 17.4% (n=12) had taken no courses, 68.1% (n=47)

had taken one to two courses, 13.0% (n=9) had taken three to four courses and 1.4%

(n=l) had taken more than four courses in the subject area. There was one student that

did not answer this specific question.

 Regarding the number of problem sets taking more than an hour to complete in a

typical week 52.9% (n=37) student participants in Class A claimed that none of the

assigned problem sets had taken more than an hour. However, 38.6% (n=27) claimed one

or two problem sets and 8.6% (n=6) of the respondents claimed three to four problem sets

assigned in class had taken more than an hour to complete.

Class B

 Class B was a three hour course focused on the principles of quantitative genetics

as applied to domesticated animals. Particular attention was given to farm animal

industries including beef, dairy, equine and poultry. Although the final grade was

calculated from exams and quizzes, mathematical problem sets were used throughout this

course in the form of homework assignments. The course was required for students in the

animal science department. The faculty member providing instruction for Class B was a

male at 54 years of age. He had taught at the University of Florida for 29 years and had

no other teaching experiences. Instruments were administered in class, but completed
