Correct answers
In order for the automatic grading to decide if a student’s answer is correct, at least one correct answer needs to be specified. The answer(s) fields can be found under the Answers tab.
An answer is made up of three parts:
- The actual answer
- A grade
- Optional feedback
It is also possible to specify multiple correct (and partially correct) answers.
Answer
The first field is the actual answer to the question.
There are two main things to know about an answer:
- The correct answer(s) must be written in LaTeX.
- ‘*’ can be used as a wildcard to match any characters.
LaTeX
Since the student’s answer is based on a WYSIWYG editor, the correct answer(s) must comply with the LaTeX generated by the editor.
For example, the expression
| [[/assets/images/latex_integral.svg | alt=definite integral of x times sin(x squared) from 1 to 2”]] |
will be evaluated to
\int_1^2x\sin\left(x^2\right)dx
by the WYSIWYG editor.
To ease the LaTeX authoring, the WYSIWYG editor might be available from the question editing form at a later stage. However, for now, the LaTeX must be manually authored.
One trick to speed up the authoring process, is to preview the question and use it’s WYSIWYG editor. The process is described here.
Wildcard
‘*’ can be used as a wildcard to match any characters.
Assume the teacher’s correct answer is written as this:
2x+*
A student response as the following
2x+3
will be marked as correct.
Grade
A grade needs to be specified for the answer. This is steps of percentage, ranging from 5% to 100%. It is also possible to specify a wrong/neutral answer, by giving it a grade of “None”.
- One of the answers should have a score of 100% so it is possible to get full marks for the question.
Feedback
The specific feedback is shown to the student after the question is completed. It is optional and can be left blank. However, it is a great way to give tailored feedback to the student. Remember, in addition to correct answers, one may provide feedback for a partially correct or even wrong answer. An example of where this can be especially useful, is when there is a known common misconception or pitfall that a lot of students do struggle with.
Multiple answers
It is possible to create multiple answers.
