You did it yoooour way

What happens if the student introduces a correct answer that we were not expecting? In other words, what happens if he gives an expression that is mathematically equivalent to the expected one, but that looks completely different to it?

Not many systems are going to be able to detect such equivalence. If the system does not contain a powerful mathematical tool, you can simply forget about it. WIRIS quizzes has built-in functionalities that check the student's answer in a mathematical fashion, so we can't show anything on the side of the teacher. It just happens.

Let us now turn to which type of equivalence we can expect. It is not simply detecting that «math xmlns=¨http://www.w3.org/1998/Math/MathML¨»«mo»-«/mo»«mn»1«/mn»«mo»+«/mo»«mi»x«/mi»«/math» is equivalent to «math xmlns=¨http://www.w3.org/1998/Math/MathML¨»«mi»x«/mi»«mo»-«/mo»«mn»1«/mn»«/math», or that «math xmlns=¨http://www.w3.org/1998/Math/MathML¨»«msup»«mi»x«/mi»«mn»2«/mn»«/msup»«mo»-«/mo»«mn»1«/mn»«/math» is equivalent to «math xmlns=¨http://www.w3.org/1998/Math/MathML¨»«mfenced»«mrow»«mi»x«/mi»«mo»+«/mo»«mn»1«/mn»«/mrow»«/mfenced»«mo»§#183;«/mo»«mfenced»«mrow»«mi»x«/mi»«mo»-«/mo»«mn»1«/mn»«/mrow»«/mfenced»«/math». WIRIS quizzes performs powerful mathematical computations in order to detect equivalences such as the following example:

A quiz system that doesn't detect such equivalences will create doubts or distress in the students. It reduces students' willingness to work and is the source of mistrust among a very well connected community: your class. Avoid such a situation by providing a sound system that can handle the unexpected.
