One of the unique things about Mathspace is the level of depth to which we accept student working (see Can different methods be used to solve questions?). Because of this, we have a range of feedback tools for the students.

The first, and simplest is the filled green tick.

This means that the student has entered a correct final answer and has completed the question.

The second is the hollow green tick.

This means that the student has entered an intermediate step that is along one of our recommended paths of working. If a student asks for hints, they will receive hints that are specific to this step, to help them move to the next step.

The third is the dotted green tick.

This means that the student has entered a step that we're not expecting, but is mathematically correct. They are marked correct, but we are unable to provide a hint for them. The hint will instead default to the last step in our recommended path of working.

The fourth is the grey question mark.

This means that the student has put in a mathematically invalid statement. Often this is because they have not entered in an equation where required, or they have left an operator hanging (e.g. 3 + ). The accompanying message should indicate what might have gone wrong.

It's important to note that Mathspace does not deduct marks for these. We will only mark mathematically valid statements.

The final symbol is the grey cross.

This means that the student has entered in an incorrect (but mathematically valid) statement. This is the only form of input where students lose marks for the question.
