Example
Reading time: 1minThis option is advantageous when, for instance, we want to ask different types of questions (like in Cloze question type), but we have to use a grading function.
As an example, we will give the students a point P , and two vectors u, v , and we will ask them some questions:
- Does P belong to a given line?
- Is u parallel to a given vector?
- Give the equation of the plane with vectors u and v and passing through P
- Give a linearly independent vector concerning u and v
- Give a vector orthogonal to u and v
We can use a multichoice question type; for the third, we can use a short answer question type with the Equivalent equations validation property selected. We should use a grading function for the last two questions because there are infinite solutions. Hence, we will create a Cloze question type for the first three questions and a short answer question type with a grading function for the last two. We will fix the random seed for each student so that the vectors u and v are the same in the two questions.
For the first question, select Equivalent equations on the Validation tab and write the following algorithm:
The statement would look like:
For the second question, the algorithm will be
A quiz with both questions will be shown as
Note that the vectors u and v are the same in both questions. Then, for instance, a student can answer the normal vector of the plane as the orthogonal vector.
