04 Parameters (LTI)
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.
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.
|  |
Additional parameters (2)In this section, configure fixed key values, such as content ID, language, etc. | |
Individual assessment and user dataAssign 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.
Specific instructions for connecting the programming learning tool are provided at Connection to the algo.bwinf platform (Nation wide computer science competitions).
User-dependent key-values
| Transfer of | Examples | General expert syntax | Example from a test course |
|---|---|---|---|
User attributes and user configuration
| Transfer of the study program | getUserProperty("[string]") | getUserProperty("studySubject") |
| Transfer of the system language | getUserProperty("language") | ||
| Membership of a specific learning group | Membership transfer to the “Beginners” learning group | inLearningGroup("[string]") | inLearningGroup("Beginners") |
| Assessment data | Score for section 1 - Score transfer of an ONYX test | getOnyxTestOutcome("[string1]","[string2]") | getOnyxTestOutcome("1670470101589006009","SCORE") |
| Assessment of course section 2 - Course element passed | getPassed("[integer]") | getPassed("84389429397045") | |
| Learning progress or processing status | Transfer of the launched trials of a course element | getAttempts("[integer]") | getAttempts("1670470101589006009") |
| Processing status (course progress). | getProgress("[integer]") | getProgress("1670470101585115009") | |
| A combination of multiple pieces of information | getUserProperty("[string1]") + getUserProperty("[string2]") + getUserProperty("[string]") | getUserProperty("firstName") + getUserProperty("language") + getUserProperty("studySubject") |
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
