Variables in Xerte Online Toolkits

April 29th, 2019 at 12:04

Xerte Online Toolkits includes an optional property called ‘Variables’ – a powerful yet under-used feature which can help add variety to projects and increase the chances of them being reused by students. Instead of hard coding a calculation or example onto a page, such as 1 + 2 = 3, variables allow you to instead use a + b = c where the value of each of these variables is calculated and inserted (according to the parameters set by you in the Xerte editor) when the project is viewed. This means that every time a project is viewed a new set of questions or examples can be displayed, helping to ensure that students understand the logic behind what they are learning rather than just memorising a single example.

The Xerte editor allows you to set a number of parameters that are be used to calculate a variable’s value on each view of the project. A value can be chosen from between minimum and maximum figures (at an increment of your choice), a value can be chosen randomly from a list, the number of decimal places and significant figures can be selected and specific values can be excluded from being allowed. Variables can also be created that rely on the value of other variables.
