LLM-Driven Course Generation

Leveraging skills-based content modeling and emerging LLM technologies, I designed and built a Python-based course content generation pipeline. The system integrates with OpenAI’s API to produce structured, educational materials from metadata, embeds multiple layers of quality assurance, and enables human-in-the-loop editorial review. This solo project proved that automated course generation can meet rigorous educational standards while achieving massive gains in speed, consistency, and scalability.

Introduction

Developing on my prior work in skills-based content modeling, I set out to explore whether emerging large language model (LLM) technologies could fundamentally change the economics and speed of course creation. What began as an experiment in Airtable evolved into a fully custom Python pipeline directly integrated with OpenAI’s GPT-4 API. The objective was ambitious: transform metadata into complete, pedagogically sound courses in hours instead of months, while maintaining human oversight and brand integrity.

The Challenge

Traditional course development at scale is slow, costly, and resource-intensive. It can take months for instructional designers, subject matter experts, and content editors to produce a single high-quality course. For my client, this pace was at odds with the evolving demands of students and the rapid proliferation of new skill areas in the market.

The goal was ambitious: radically shorten development timelines without compromising the educational integrity of the output. That meant tackling several core challenges: maintaining context across multiple AI-generated outputs, automating quality checks that could match human judgment, building a technically sophisticated pipeline with minimal engineering support, and integrating an efficient human review process without negating the speed gains of automation.

Key Objectives

Automate Content Generation

Build a pipeline that transforms structured skill and course metadata into complete, coherent educational materials.

Maintain Pedagogical Quality

Ensure AI-generated content meets established educational standards and aligns with institutional goals.

Enable Human Oversight

Integrate intuitive editorial tools for review, refinement, and regeneration of content.

Establish Quality Controls

Implement automated validation for coherence, context, style, and standards compliance.

Prove Scalability

Demonstrate the feasibility of rapid, high-volume course generation without quality loss.

Integrate with Existing Systems

Output content in formats compatible with the institution’s design system and platform requirements.

Approach

Phase 1 — Proof of Concept
I began by storing structured skills metadata in Airtable and testing prompt engineering with GPT-3.5 to produce basic text blocks. This allowed me to explore chain-of-thought prompting and iterative refinement.

Phase 2 — Custom Pipeline Development
Realizing Airtable’s limitations, I built a Python pipeline to handle prompt orchestration, context management, and structured JSON output via GPT function calling. Outputs were mapped to our design system and rendered as React components.

Phase 3 — Quality Assurance Layer
Introduced coherence scoring, topic modeling, perplexity/burstiness checks, and automated alignment against educational standards. Created a quality metrics dashboard for real-time feedback.

Phase 4 — Human-in-the-Loop
Developed an editorial interface allowing reviewers to edit, approve, or regenerate specific content blocks. This safeguarded quality and ensured brand consistency while preserving AI speed gains.

Test
Building upon the skills-based instructional content model I designed, I considered how a hierarchal structured content model like this might serve a prompting logic change, passing down direction from parent to child to drive instructional content writing at a lesson level.
Each skills contains a set of objectives, and prompting rules can be attached to each objective node as a means for driving instructions towards complexity.

Solution

The resulting system was a carefully orchestrated blend of automation, quality assurance, and human oversight; a pipeline that could take structured skill metadata and output complete, platform-ready courses in hours.

At its core was a Python-based AI generation engine integrated with OpenAI’s GPT-4 API. Prompts were engineered to produce structured JSON outputs that mapped directly to the institution’s design system, ensuring that generated content was both pedagogically structured and immediately publishable.

To safeguard quality, I implemented a multi-layer validation system. Coherence scoring ensured that lesson modules flowed logically; topic modeling detected unwanted context shifts; perplexity and burstiness checks maintained a natural writing style; and automated standards alignment verified that outputs met educational and institutional benchmarks.

Recognizing that AI alone could not account for nuance, I developed a human-in-the-loop editorial interface. Editors could review AI-generated modules, make inline adjustments, regenerate sections where necessary, and push final content directly into the production pipeline. This ensured that the system didn’t just automate content creation — it empowered human reviewers to focus on the areas where judgment, empathy, and institutional voice mattered most.

Finally, seamless design system integration ensured consistent styling, accessibility, and responsiveness across all generated content. This meant that the leap from metadata to published, branded course material was frictionless, repeatable, and scalable.

The result was a transformation in how course materials could be produced: a months-long process compressed into a matter of hours, without sacrificing the quality and integrity that define effective education.

Reflection

This project demonstrated that LLMs can meaningfully automate course development without lowering quality, provided there’s strong content architecture, rigorous QA, and human oversight. It’s a proof point for “instructional content as commodity,” lowering barriers to creating high-quality educational experiences at scale. Yet it also reinforced that AI is an assistant, not a replacement, for the human judgment, creativity, and ethics that shape great learning.
