The exercise types 'Radio Button' and ‘Radio Button Random’ require users to select precisely one answer choice from a defined list of options.
❗ Note: This exercise type is very similar to “Multiple Choice (Random)”. The difference is that in Multiple Choice (Random), students can select one or multiple answers instead of having to select precisely one answer.
Options can be added by clicking on “+Add” -> “New option” in the Texts tab of the exercise.
You can add as many options as you like. Your exercise will look as follows:
And the student will see the following:
Options can contain text, but also images, applets, tables and other items. It is also possible to use variables in the options. Every option has a number, which can be used to refer to this option in the Solutions or Negative feedback tab.
Difference between Radio Button and Radio Button Random
In Radio Button, the options are displayed to the student in the order in which you define them, e.g. Option 1, Option 2, Option 3 …
In Radio Button Random, the options are displayed to the student in random order.
To define a solution, put the number of the option that has the correct solution in the Definition field.
You can define multiple correct solutions by clicking “+ Add solution”. If multiple correct solutions are defined, the student will get full grades if they select one of the options that were defined as correct.
Defining negative feedback is similar to defining solutions. Put the number of the option that you want to give feedback on in the Definition field.
If the box “opposite evaluation” is checked, the feedback rule will be hit when the option in the Definition field is not selected.
