====== Adaptive Content: Source Interaction > Open Answer ======

**Source Interactions** can be thought of as links to Interactivity pages with instructions to record performance on them in specific ways. It is possible to add several Source Interactions to an **Adaptive Content** page to create the effect of a dashboard.

The **Open Answer** Interaction Type (selected from a drop-down list - see table below) displays responses to open-answer tasks on **Model Answer** pages, by the learner and all other learners.

==== New Source Interaction > Open Answer: Core Properties ====

^ **Property** ^ **Description** ^ **Type** ^ **Additional information** ^
| Title | Title for this Source Interaction | Text |   |
| Introduction | Text that is displayed before performance data | Text+ |   |
| Interaction type | Select **Open Answer** from the drop-down | Drop-down |   |
| URL of Xerte source installation | The URL of the Xerte installation from which the data is retrieved - you need to end this with a forward-slash (e.g. [[https://xerte.org.uk/]]). | URL |   |
| ID of Xerte learning object | The ID of the Xerte project from which the data is retrieved - this can be the same learning object or another one within the same installation | Number | The ID is automatically generated when the project is created, and can be read from the Project Details. |
| Tracking Label of source | This makes a link between the Interactivity page, whose data you want to display, and this Adaptive Content page.  You need to a) add a Tracking Label **on the Interactivity page**, as an Optional Property and b) enter the same Tracking Label **in the Source Interaction properties**. You must use **unique labels**, with underscores, numbers and letters, but no other types of character. | Text | It is a good idea to use short, but meaningful, Tracking Labels, because these are also displayed to learners on the Results Page.  |

==== Source Interaction > Open Answer: Language Options ====

Some of these relate to the text used to introduce scores, number of questions on an Interactivity page, and numbers of learners completing the page. Others relate to labels on graphs and their axes.
