About the Multiple choice question in DigiExam
The multiple choice question is a question type that is answered by choosing one or more alternatives. It is possible to choose if one or more alternative needs to be chosen for the multiple choice question to be correctly answered.
When using score based grading multiple choice questions are automatically graded.
When using a grading rubric the multiple choice questions are not automatically graded.
There are two grading options for multiple choice questions, "All or nothing" and "Right minus wrong", they are explained in more detail below.
All or nothing
The student must check all correct alternatives to get the max points. If the student misses any of the correct alternatives or checks any of the incorrect ones, the student is awarded zero points.
In figure 1 below there is an example of a multiple choice question in the edit view of an exam with the grading option "All or nothing" activated.
The examples below are based on the question in figure 1.
Example 1: Student 1 selects Physics and Chemistry and awarded 2 points
Example 2: Student 2 selects Physics and Literature and awarded 0 points
Example 3: Student 3 selects Literature and Medicine and awarded 0 points
Example 4: Student 4 selects Physics and awarded 0 points
Right minus wrong
The student gets plus points for each correct alternative and a minus score for each incorrect alternative. Each alternative is worth the maximum score for the question divided by the number of correct alternatives. The lowest score awarded is zero, so it is not possible to receive minus points (for example -1) for a question.
Figure 2 below shows an example of a multiple choice question that is added to the edit view for an exam with the grading option "Right minus wrong".
The examples below are based on the question in Figure 2.
Example 1: Student 1 selects Canberra, New Delhi and Copenhagen and is awarded 3 points
Example 2: Student 2 selects Canberra and is awarded 1 point
Example 3: Student 3 selects Canberra and New Delhi and is awarded 2 points
Example 4: Student 4 selects Canberra, New Delhi and Gothenburg and is awarded 1 point
Example 5: Student 5 selects all options and is awarded 0 points
Example 6: Student 6 selects no options and is awarded 0 points
Example 7: Student 7 selects Mumbai, Sydney and Gothenburg and is awarded 0 points
Multiple choice question from a student's perspective
The student will see the same multiple choice question structure wether the grading type is "All or nothing" or "Right minus error". See examples of multiple choice questions when the student answers them in Figures 3 and 4 below.
