04 Parameters (LTI)

Last modified by Anna Paul-Hasenfuss on 16.02.2026

Whenever external learning content is integrated into a course via the LTI tool course element, the learning platform transfers information to the external tool when the LTI link is used. This data transfer enables the tool to clearly identify the course, the participant, and the respective situation of use.

Apart from anonymous context information, you can specify which additional information should be sent to the LTI tool in the Parameters tab of the LTI Tool course element.

Information

Exact data transfer depends on the LTI settings in the course and the requirements of the integrated tool. Check the Data and parameters transfer via LTI page for general information on data transfer to an LTI tool.

Configurations in the parameters tab

The following areas are available:

User Data (1)

Activate the checkboxes for the optional user information you require.

The participant is required to actively consent to the transfer of this data in the course view before they can use the LTI tool.

Kurseditor - Tab Parameter1_de.png

Additional parameters (2)

In this section, configure fixed key values, such as content ID, language, etc.

Individual assessment and user data

Assign a separate parameter name (3) in this section and enter the required user-dependent values such as user attributes, user settings, evaluation or progress data via expert rule (4) in the text field. The result of the entered expert rule is transferred to the LTI tool as a string. The Preview button (5) offers a test evaluation.

The participant is required to actively consent to the transfer of this data before they can use the LTI tool.

Configuration of the values - examples

Key values

Example configuration with a fixed key-value pair from a connection to a programming learning tool. The transferred parameter “task=juice-setvar-interactive” only shows the user the specific programming task in the course run.

Information

Which key-value parameters can be transferred depends on the connected LTI tool and should be documented there.

Specific instructions for connecting the programming learning tool are provided at Connection to the algo.bwinf platform (Nation wide computer science competitions).

Further examples of creating expert rules can be found in the section Application examples for expert rules and Expert syntax.

Information

Using an IMS test tool is a good way to check the technical aspects of transferred data. Further information on creation and configuration can be found on the page https://lti-ri.imsglobal.org/lti/tools
