Assessment variables allow you to create questions that use different values for each student, presenting them with varied questions and answers.
You can create two kinds of assessment variables in Pearson Connexus: Ranges and Lists.
Variable range values are always numbers. When you create a variable range, you provide a minimum and maximum number. When you use that variable range, Pearson Connexus randomly generates a number using those parameters.
Create a variable range
To create a variable range:
- Select Range and:
- Name the variable range (don't use spaces or special characters).
- Provide the lowest number you want included in the range in the Min field (you can use decimals and negative numbers).
- Provide the highest number you want included in the range in the Max field (you can use decimals and negative numbers).
- Provide the increments between Min and Max that you want included in the Step field. For example, if you specify 1, every whole within the parameters could be used. If you specify 2, only every other whole number can be used (you can use decimals).
- Select Done.
Use a variable range
Once you have created a variable range, you can use it in questions and answer options.
This example uses two variable ranges in a multiple choice question. Here's how they're used:
- Place the variable range Name between dollar signs ($) to signal Pearson Connexus to use the variable range
- Within a question, Pearson Connexus generates the same number for every instance of the variable range. This allows you to create answer options that use the same number that's generated in the question.
- You can create math problems using variable range and have Pearson Connexus show the solution by:
- Typing the math problem in parentheses.
- Adding $eval in front of the parenthesis.
- Adding a comma and a number sign (#) the end of the problem, inside the parentheses.
- You can indicate how many decimal places you'd like included by adding a decimal and the desired number of places as zeros after the number sign (#) and inside the parentheses.
This question is now generated differently for each assessment attempt, as in the two instances shown here.
Variable lists allow you to create a set of items, each of which can be swapped in at random anywhere you want in a question.
Create a variable list
To create a variable list:
- Select List and:
- Name the variable list (don't use spaces or special characters).
- Provide a Group title (don't use spaces or special characters).
- Provide the Values for the items in the list in a list.
- Select Done.
Use a variable list
Once you have created a variable list, you can use it in questions and answer options.
More than one variable list can be part of the same Group, allowing you to align items between multiple variable lists in one question. To do this, you use the same Group title for multiple lists with different Names. For example, one variable list in a Group titled animalgroupings could list animals (with Animals as the Name), and a second list with the same Group title might list the terms used for groupings of those animals (with Terms as the Name). The items align by position in the list, like this:
- Name: Animals, Group: animalgroupings, Values: dogs, cows, crows, geese
- Name: Terms, Group: animalgroupings, Values: pack, herd, murder, flock
This example uses these two variable lists (Animals and Terms) as part of the same Group (animalgroupings) in a multiple choice question. To reference the variable lists in the question, you place Group.Name between dollar signs ($), like this:
This question is now generated differently for each assessment attempt, as in the two instances shown here. Notice that the items from each list align correctly.
