LTI bridges the gap between eLearning platforms. It allows you to incorporate a rich ecosystem of educational resources into your LMS without the hassle of manual configurations or compatibility issues. This comprehensive guide will delve into the intricacies of LTI Integration with your LMS. LTI empowers you to streamline your eLearning workflow and deliver a unified learning experience for your students.
What is LTI and How LTI Works?
Before diving deep into the implementation of LTI with the LMS process, first, we need to understand the basic LTI key terms like what LTI is and how it works.
Learning Tools Interoperability(LTI) is an educational technical standard developed by the IMS Global Learning Consortium that facilitates communication between an LMS and a wide range of eLearning tools. The latest version of LTI v1.3, completed using OAuth2, OpenID Connect, and JSON Web Tokens.
LTI Workflow
The Learning Tools Interoperability (LTI) standard enables seamless integration of external learning tools into learning management systems (LMSs). This allows instructors to easily incorporate third-party resources into their courses that enhance the learning experience for students.
1. Tool Configuration
The external tool administrator provides the LMS administrator or instructor with a URL, key, and secret for the tool. In the instructor use case, the instructor adds the LTI tool to the course structure using the LMS control panel. In the administrator use case, a "virtual tool" is added to the LMS.
2. LMS Integration
Instructors add the LTI tool as a resource link in the course structure and enter the URL, key, and secret as metadata. The LMS may display the external tool seamlessly within its interface which makes it appear as if it's a native component.
3. User Launch
When students or instructors select the LTI tool, the LMS generates a launch request that includes user identity, course information, role details, a key, and a signature. This launch information is embedded in an HTTP form, created in the user's browser with hidden form fields, and submitted to the external tool using JavaScript.
4. Security Verification
The data in the HTTP form is signed using the OAuth security standard to ensure the integrity of the launch data. The external tool uses the key and signature to verify that the data has not been altered between the time the LMS generated and signed it and the time the external tool received it.
5. Tool Response
After receiving the launch request, the external tool may choose to redirect the user's browser to another URL or immediately render the requested user interface. The tool utilizes the information in the launch request, such as user identity and course details, to customize the user experience.
6. User Interaction
Users interact with the external tool, which may include engaging in educational activities, accessing content, or participating in assessments.
7. Data Exchange
The LTI standard supports the exchange of data between the LMS and the external tool, facilitating the transfer of grades, progress, or other relevant information.
This workflow allows for a cohesive integration of external learning tools. Provides a unified learning experience for both instructors and students without the need for multiple logins or troubles.
LTI Integration: Bridge the Gap in eLearning
LTI integration, short for Learning Tools Interoperability, involves establishing standardized connections and communication channels between different e-learning applications and platforms.
This integration enables a Learning Management System (LMS) to initiate external tools and services securely, granting them access to a predefined set of user data. It streamlines the user experience by allowing students and teachers to engage with various learning tools directly within the main LMS, eliminating the need for separate logins for each tool.
For instance, an instructor seamlessly incorporates an external grading tool, an e-portfolio, a digital textbook, or a video lecture platform into their LMS. With LTI integration, these resources are easily embedded within the LMS. And allow users to access and interact with them as if they were integral components of the original system.
LTI integration extends beyond mere accessibility by enabling data exchange between integrated systems. It facilitates the sharing of user data, such as grades, activity reports, and progress tracking, between the LMS and the integrated tools, providing a holistic view of a learner's progress.
Importance of LTI for eLearning
Learning Tools Interoperability (LTI) has become a crucial standard in the e-learning landscape, playing a pivotal role in enhancing the learning experience and streamlining the integration of external tools into learning management systems (LMSs). Here are some key reasons why LTI is important in eLearning:
Seamless Integration of External Tools
LTI enables the effortless integration of external learning tools into LMSs and eliminates the requirement of manual data entry or custom programming. This allows instructors to easily incorporate a wide range of third-party resources, such as simulations, videos, interactive assessments, and social learning platforms, into their courses.
Enhanced Learning Experience
By providing access to a diverse array of external tools, LTI empowers instructors to create more engaging and interactive learning experiences for their students. Students can explore various learning models and gain exposure to different perspectives that lead to a deeper understanding of the subject matter.
Simplified Tool Management for Instructors and Administrators
LTI simplifies the management of external tools that reduce the burden on both instructors and administrators. Instructors can easily add and configure LTI tools within their courses, while administrators can centrally manage tool configurations and access permissions, ensuring consistency across the LMS.
Enhanced Data Exchange
LTI facilitates the exchange of data between LMSs and external tools that allow seamless grade integration and performance tracking. Instructors can automatically receive grades from external tools. In addition, it eliminates the requirements for manual data entry and streamline the assessment process.
Promotes Open Learning Ecosystem
LTI contributes to the development of an open and interconnected learning ecosystem. By enabling seamless integration with a vast array of external tools, LTI encourages innovation and collaboration among tool developers, content providers, and educational institutions.
Expands Learning Opportunities
LTI extends the reach of learning beyond the boundaries of the LMS. Students can access external tools and resources from anywhere, anytime, using various devices and promote continuous learning and self-directed learning.
Improved Security
LTI incorporates robust security protocols to protect sensitive user data and ensure the integrity of data exchanged between the LMS and external tools. This emphasis on security safeguards the privacy of learners and ensures that their personal information is handled responsibly.
Role of Deep Linking in LTI Protocol
Deep linking is a feature of the Learning Tools Interoperability (LTI) protocol that enables users to navigate directly to specific content within an external tool. This enhances the user experience by providing a more seamless and contextual learning journey.
The LMS sends a new message type called the "Content Item Selection Request Message" to the external tool, including the following information.
- The URL of the content item that the user wants to launch into
- The context of the launch, such as the course or group that the user is currently in
- The external tool then uses this information to launch the user into the specified content item.
Deep linking can be used for a variety of purposes, such as launching users into specific pages or sections of an external tool, activities or assessments within an external tool, and content items within an external tool.
Difference Between SCORM xBlock Vs. LTI Protocol
SCORM (Sharable Content Object Reference Model) and LTI (Learning Tools Interoperability) are two different standards for packaging and delivering eLearning content.
