Showing mathematical "work"
One important aspect that math teachers in the regular classroom
use to grade homework turned in involves following a student's "work," or
the specific steps a student used to solve a particular problem.
Since there is no reasonably inexpensive, compatible software in
existence that allows this to be easily done on-line, CLASS™ courses
provided very limited opportunity for students to show their work
on graded exams and assignments.
E-mail correspondence, with the limitations of the standard keyboard,
was really the only option for a student to show the teacher how
a particular math problem was solved. Hence, graded answers are either
right or wrong, no matter what effort was given in solving the problem.
This is a limitation that on-line teachers and learners must deal
with until an appropriate software programs are developed.
