Discussion Boards in an AI World

A common pattern looks like this: a student copies your discussion prompt into a large language model (LLM) like ChatGPT or Gemini and pastes the generated answer as their own post. When it’s time to reply to peers, they copy a classmate’s response back into the LLM and paste the “peer reply” it provides. The result? A conversation of bots talking to bots: efficient, maybe, but not conducive to learning.

The good news is that we can design discussion boards that invite authentic student thinking and make AI shortcuts unattractive or easy to spot. Here are five proven strategies.

Use Multimedia to Change the Medium of Expression

Discussion boards don’t have to be all text. Try formats like:

  • a narrated two-minute video (with captions) explaining a concept, experience, or reflection.
  • an annotated image or infographic that visually represents an argument, process, or comparison.
  • a brief podcast-style reflection sharing insights or relevant stories.

For peer responses, invite students to engage through the same or complementary media, such as replying to a classmate’s video reflection with their own video response or providing embedded feedback by adding comments or highlights directly within a copy of a classmate’s infographic.

Ask for Highly Specific, Personalized, Contextual Responses

LLMs are good at generic writing but often falter when prompts are tied to unique contexts. For example:

  • “Identify a challenge or opportunity in your local community. Describe the issue in detail and propose one actionable improvement.”
  • “Analyze hospital staffing data from your own department and propose a scheduling solution.”
  • “Think back to a formative learning experience from your own education or career. Describe the setting, what made it memorable, and how it shaped your approach to learning or professional growth.”

Gather student context early (e.g., interests, workplaces, local issues). By getting to know your students and asking them to work through personal/local applications, you should be able to identify whether discussion posts accurately reflect their experiences and perspectives.

Lean Into Authentic Assessments

Authentic assessments ask students to apply course knowledge and skills to complex situations that mirror the real world. Have your students tackle realistic, context-rich tasks that require applying course concepts and defending their decisions, such as:

  • designing a training plan for their workplace.
  • analyzing a local environmental issue.
  • developing a community outreach proposal.

Require them to explain the how and why of each choice and to reflect on possible next steps.

Require Course-Specific Evidence

Ask students to support their ideas with specific references to course materials, such as timestamps in lectures, quotes from assigned readings, or references to previously covered topics. Prompts might include:

  • “Refer to at least one example, quote, or concept from this week’s video lecture. Include the timestamp and explain how it connects to your post.”
  • “Cite a specific quote from one of our assigned readings that supports or challenges your argument.”
  • “Reference a key concept or application from last week and explain how it connects to this discussion.”

Clearly state these expectations in your discussion instructions and grading criteria so students understand that references to course materials are required components of participation.

Have Students Keep an AI Usage Log

Explicitly allow students to use AI but ask them to document:

  • the exact AI prompts they used.
  • the raw AI output.
  • how they revised or built upon it.

This transparency discourages wholesale copy-paste. Mismatches between the declared process and the final post can quickly flag questionable work.

The Big Picture: Make It Worth Answering

These strategies should help you avoid the dreaded “AI talking to AI,” but they’re only part of our recommended approach. Students often turn to AI because it seems faster or easier. When you make a strong case that your discussion boards are worth their time and creativity, that temptation drops.

Ultimately, students are more likely to engage honestly if the discussion is dynamic, relevant, and uniquely theirs. When discussions spark curiosity and ownership, authentic participation outshines anything a bot can produce.
