TLDR: Instructional Agents is a new multi-agent large language model (LLM) framework designed to automate the end-to-end generation of high-quality course materials, including syllabi, lecture scripts, slides, and assessments. It simulates role-based collaboration among educational agents (e.g., Teaching Faculty, Instructional Designer) following the ADDIE framework. The system offers four operational modes, from fully autonomous to human-in-the-loop (Full Co-Pilot), allowing flexible control over human involvement. Evaluations across five computer science courses show that while autonomous modes are efficient, human-guided modes significantly improve material quality, reducing educator workload and offering a scalable solution for institutions with limited instructional design capacity.
Preparing high-quality educational materials can be a time-consuming and complex task, often requiring collaboration among various educational professionals. This process typically involves extensive coordination between teaching faculty, instructional designers, and teaching assistants to develop everything from syllabi to lecture slides and assessments.
A new multi-agent large language model (LLM) framework, called Instructional Agents, has been developed to automate the entire process of generating course materials. This innovative system aims to create cohesive and pedagogically sound content, including syllabi, lecture scripts, LaTeX-based slides, and assessments, from start to finish. Unlike many existing AI tools that focus on individual tasks, Instructional Agents simulates a collaborative environment among different educational roles to produce integrated content.
How Instructional Agents Works
The framework operates by mimicking the roles of various educational professionals: Teaching Faculty, Instructional Designer, Teaching Assistant, Course Coordinator, and Program Chair. These agents work together, guided by the well-known ADDIE instructional design framework (Analyze, Design, Develop, Implement, Evaluate), to ensure that learning objectives, assessments, and content are all aligned.
The system functions in four distinct modes, offering flexibility in how much human involvement is desired:
- Autonomous Mode: The system generates all materials without any human intervention beyond the initial course topic.
- Catalog-Guided Mode: It incorporates existing institutional data or instructor preferences (like predefined course structures or policies) to guide content generation.
- Feedback-Guided Mode: Allows human reviewers to provide suggestions for improvement after content is generated, enabling iterative refinement.
- Full Co-Pilot Mode: This mode simulates a true collaborative workflow, pausing after each subtask to solicit real-time user feedback and integrating structured preferences from an educator catalog.
Key Phases of Material Generation
Instructional Agents follows the first three phases of the ADDIE model:
Analyze Phase: This phase focuses on understanding the course goals, student profiles, and logistical constraints. Agents collaborate to define learning objectives, analyze the target audience’s background, and assess available resources.
Design Phase: Here, the course structure and assessment strategies are organized. Agents work together to create a syllabus with weekly topics, outline instructional methods, and design assessments that align with learning objectives. This includes planning for slides and defining assessment types, moving away from traditional exams towards project-based capstone projects.
Develop Phase: In this final phase, the instructional plans are transformed into complete, classroom-ready materials. This involves generating LaTeX-based slides, slide scripts, and assessments. The system also includes validation by expert agents and pilot testing with simulated student agents to ensure quality and usability.

Evaluating the System’s Effectiveness
The researchers evaluated Instructional Agents across five university-level computer science courses. They assessed the quality of generated materials (Learning Objectives, Syllabus, Assessments, Final Slides, Slide Scripts, and the overall Instructional Package) using an adapted Quality Matters rubric, involving both human and automated LLM reviewers.
Key findings include:
- All three tested LLM backends (gpt-4o, gpt-4o-mini, o1-preview) produced high-quality materials, with gpt-4o-mini offering comparable performance at a significantly lower cost.
- Human evaluators provided more nuanced and sensitive assessments of quality compared to automated LLM reviewers, who tended to give more moderate scores.
- Operational modes with greater human involvement, especially Full Co-Pilot Mode, consistently achieved the highest quality scores, improving results by 0.5 to 0.9 points over Autonomous Mode on a 5-point scale.
- There are clear trade-offs between automation, quality, and cost. Autonomous Mode is the most efficient but yields lower quality, while Full Co-Pilot Mode offers the best quality at higher computational and human costs.
While the system significantly reduces development time and human workload, some limitations were noted, such as occasional LaTeX compilation errors for slides and a lack of visual or interactive elements in the generated content. Ethical considerations, including potential biases from training data, are addressed by emphasizing human oversight and review.
Instructional Agents holds significant promise for democratizing access to high-quality education, particularly in underserved or resource-constrained settings by providing a scalable and cost-effective framework for course material generation.
