Calculated multichoice questions are like multichoice questions with the additional property that the elements to select can include formula results from numeric values that are selected randomly from a set when the quiz is taken.
They use the same wildcards than Calculated questions and their wildcards can be shared with other Calculated multichoice or regular Calculated questions.
The main difference is that text and the formula can be included in the answer choice as {=…}.
Text added to choice
In this example we want the user to see text in the answer along with the answer. Given a question written by the instructor as:
Calculate the area of a rectangle where l = {A} cm and h = {B}cm.
The correct answer choice text written by the instructor would be:
The rectangle's area is {={A}*{B}} cm2.
The correct answer’s choice will display as:
The rectangle area is 10.0 cm2
The variables picked by the dataset in the example were {A} = 4.0 {B} = 2.5 .
Showing a formula as a choice
In this example, we want the user to demonstrate they know how to correctly factor out a binomial equation. We want every user to have a unique problem to solve.
For example, the instructor enters the question as:
Given the binomial equation 3x2+5xy+2y2, where x = {A} and y={B} how would you simplify it before solving it?
The correct choice would be written:
This polynomial can be reduced to (3*{A}+2*{B})({A}+{B}).
This choice would display as:
This polynomial can be reduced to (3+4)(1+2).
