Formula - Form Variant

Question Mode: Formula (with "form" grading variant invoked)

qu.x.y.mode=Formula@

qu.x.y.grading=form@

The Formula - Form Variant question type is a new restricted-grading variant of the Formula question tyep. When this mode is selected, the student response is required not only to be mathematically equal to the correct answer, but also to be expressed in the same form.

Thus

(x-1)(x+1)

(x+1)(x-1)

and

(x^2-1)

would all be graded the same by an ordinary formula question. However, with the Form submode set, only the first two would be graded as equivalent.

Authoring of this question variant is not currently available from within the QBE. Instead, to invoke this grading variant you must edit your EDU question script. You can either specify it in LaTeX or edit the source for the question. When editing the source, you would include a line like "qu.1.1.grading=form@"
