Transitioning grade data from LTI 1.1's Basic Outcomes to LTI 1.3's AGS involves addressing differences in how scores and feedback are handled. The main hurdle lies in reconciling Basic Outcomes' single-score approach with AGS's expanded capabilities, which include multiple score types, detailed feedback, flexible grading scales, and asynchronous updates.
Feature | Basic Outcomes (LTI 1.1) | AGS (LTI 1.3) |
---|---|---|
Score Types | Single numeric score | Multiple score types |
Feedback | Limited text | Detailed feedback with timestamps |
Grade Scale | 0–1.0 scale only | Flexible scoring scales |
Update Method | Synchronous updates | REST-based services |
To ensure grades remain accurate and consistent, a translation layer is essential. This layer should:
Synchronizing grades effectively also depends on a solid user mapping strategy to align data across versions.
To maintain consistent user identities between LTI 1.1 and LTI 1.3, map LTI 1.1's user_id/context_id to LTI 1.3's JWT sub claims. A persistent identity management system is critical to ensure users are recognized as the same individual, even when accessing content through both versions. This requires a robust mapping database that connects older LTI 1.1 identifiers with LTI 1.3 claims, preserving user data, permissions, and history.
Key components of identity management include:
Once data and identity mapping are in place, transferring content between LTI versions becomes more manageable. Adapting deep linking plays a key role in ensuring smooth content migration.
An effective content transfer strategy includes:
For the best results, implement a version control system to monitor content changes across LTI versions. This approach not only ensures consistency but also provides the ability to roll back changes if necessary.
In mixed LTI environments, ensuring secure connections is non-negotiable. Every connection, including endpoints, must utilize HTTPS with TLS 1.2 or higher to protect data during transmission.
Here’s a breakdown of the key components for a secure connection framework:
Security Component | LTI 1.3 Requirement | Implementation Method |
---|---|---|
Protocol | HTTPS with TLS 1.2+ | Configure server settings accordingly |
JWT Validation | Compliant with IMS Security Framework | Use automated validation services |
Token Handling | Time-sensitive, signed tokens | Employ JWT validation middleware |
These elements create a solid foundation for secure, cross-version communication.
Beyond secure connections, managing permissions effectively is another critical layer of protection. As organizations migrate from older systems to LTI 1.3, permission mapping becomes essential to close security loopholes. Collaboration between IT security teams and instructional designers ensures that permissions meet both technical and educational needs.
Key practices for managing permissions include:
After updating permissions, it’s vital to align user roles across systems. A role mapping matrix ensures that legacy roles translate smoothly to their LTI 1.3 equivalents, maintaining consistent access levels.
Legacy Role | LTI 1.3 Equivalent | Access Level |
---|---|---|
Instructor | Faculty | Full course management |
Teaching Assistant | Mentor | Limited course management |
Student | Learner | Content access only |
Administrator | System Admin | Platform-wide access |
For example, a large university successfully integrated LTI 1.3 tools into its legacy LMS by enforcing TLS 1.2+ for all connections, automating JWT validation, and using custom middleware for role mapping. Regular security audits and IMS Global conformance testing ensured compliance and prevented unauthorized access, delivering a secure and seamless experience for users.
To maintain ongoing security compliance, consider these steps:
Lastly, using IMS Global’s conformance test suites regularly ensures that your security measures remain effective and up to date with the latest standards.
Shifting to LTI 1.3 requires thoughtful and systematic preparation. This phase tackles earlier hurdles, such as compatibility with older systems and complex authentication processes.
Creating a well-structured update timeline that aligns with the academic calendar is key to minimizing disruptions. Start by thoroughly evaluating your current LTI integrations, classifying them into essential tools and supplementary ones. This evaluation lays the groundwork for a step-by-step implementation plan.
Phase | Timing | Activities |
---|---|---|
Assessment | Summer Break | Inventory tools, check compatibility |
Testing | Fall Semester | Pilot non-critical tools |
Implementation | Winter Break | Upgrade critical systems |
Full Deployment | Spring Semester | Roll out campus-wide |
By adhering to this phased schedule, you can automate system integrations to make the transition smoother.
