Why ChatGPT Fails at Instructional Design (and How Sarah Got Her Sanity Back)

A learning designer in a green sweater reviews her laptop with a pen poised over course notes at a sunlit home office desk.

A Golden Retriever in a Spacesuit

A few months ago, a senior instructional designer named Sarah shared a realization with me. She said that asking a standard Large Language Model (LLM) to design a comprehensive curriculum is a lot like asking a golden retriever to build a space shuttle. You get an impressive amount of effort, boundless enthusiasm, and a lot of tail-wagging, but the final product is absolutely not flight-ready.

It’s a funny image, but we need that kind of humor right now. My feed is full of breathless posts about how ChatGPT can build a fully functioning training deck in three seconds flat. The implication? Instructional design has been solved by an algorithm. But anyone who actually does the work knows this is an exaggeration.

The Magic Wand Illusion

The argument for generic AI usually goes like this: It can vomit out text at warp speed. It can give you ten scenarios before your coffee gets cold. Just type in your SME notes, cast a spell, and you’re done.

Sarah bought into the magic wand theory. She was staring down a mountain of raw interview transcripts and a deadline that belonged in a sci-fi novel. She opened up a standard chat tool, hoping it would respect Bloom's Taxonomy, follow Gagné's 9 Events, and format everything cleanly.

Technically, the AI could do it. But only if Sarah was willing to write 400-word prompt chains and barter with a chatbot that periodically forgot its own rules. ("No, please stop using bullet points inside table cells!") Instead of becoming a super-powered designer, Sarah found herself handed a brand new full-time job: prompt whisperer.

Babysitting the Machine

Look closely at what happens when you rely solely on generic LLMs for complex instructional design. Generic models simply predict the next most likely word. They are designed to sound confident, not to understand the human brain.

Sarah found herself trapped in a comedy of errors. First, there was the scope drift. The AI constantly generated exercises that wandered away from core learning objectives, adding fluff that spiked the learner's cognitive load. Then came the hallucinations. Because these tools prioritize smooth prose over factual accuracy, she had to play detective, catching the AI casually making up industry statistics.

Finally, the copy-paste nightmare. Tweaking a single objective didn't magically update her slides or facilitator notes. She was acting as a human copy machine across dozens of disconnected files.

She wasn't saving time. She was spending more energy babysitting a bright but reckless toddler than she was actually designing learning experiences. Prompt fatigue was giving her afternoon headaches.

The Right Tool for the Real Job

Here is the core issue. Instructional design isn't about generating words quickly. It's about cognitive scaffolding, managing working memory, and aligning practice with performance. Generic AI doesn't know learning science.

Sarah realized she didn't need to write better prompts; she needed software that understood pedagogy out of the box.

When she switched to a purpose-built engine like Nuralia, the dynamic shifted entirely. Because Nuralia has cognitive frameworks (like Gagné’s and Bloom’s) hardcoded into its architecture, the AI naturally constrains its outputs. Sarah didn't have to enforce the rules; the platform did it for her. It automatically synced her master blueprint downstream to her slides and facilitator guides. It stripped out the decorative fluff and strictly used her SME data.

Reclaiming the Architect Role

None of this means AI doesn't have a place in our field. It absolutely does.

But designers who thrive won't be the ones writing the longest ChatGPT prompts. They will be the ones who leverage science-backed tools to handle the heavy lifting of generation, so they can get back to their real job: being strategic learning architects. They will spend their time diagnosing performance problems, consulting with stakeholders, and ensuring the cognitive depth is right.

So, before we declare that generic chatbots have mastered instructional design, let’s be clear: fast text generation is not sound learning design. The wisdom to know how people actually learn is the scarce resource and that matters more today than ever.
