Imagine this: you open a lesson screen and find a full 25-page PDF pasted into a textbox. No breaks. No questions. No clear goal. Somewhere in there is probably a helpful sentence and some lifechanging content. But, you’re five paragraphs deep and still trying to figure out why you're reading about workplace stress when the lesson title said “Conflict Resolution Basics.”
Now imagine that screen is being read on a tablet. In a correctional facility. With tons of action around you. No clickable links. No coffee.
In the wise words of Scooby-Doo: “Ruh-roh.”

What it is:
Chunking is the process of breaking down long, complex content into smaller, manageable parts—each with a single purpose. In adult learning, it’s the difference between “Tell me everything about budgeting” and “Let’s start with what a budget is.”
What the science says:
According to Miller’s Law, our working memory can hold about 4 meaningful items at a time (Cowan, 2010). Too much info at once? Learners start triaging and drop what feels non-essential. Chunking increases comprehension and retention—especially for novice learners (Sweller, 1988; Mayer, 2009).
And yes, this works especially well in high-stress environments where distractions, anxiety, or low reading stamina are in play—like incarceration.
The problem with uploading a 60-minute video or 10-page PDF and calling it “a lesson” is that it assumes learners already know how to:
Pace themselves
Filter what matters
Stay engaged for long stretches
Self-regulate when confused
But incarcerated learners often return to education after years (or decades) away. Many face trauma, shame, cognitive fatigue, or simply lack the scaffolding to manage massive info dumps.
So no, the 1-hour video is not more “thorough.” It’s just more overwhelming.
Let’s walk through exactly how to break it down, no guesswork required.
Meh: Upload it all on one screen with the title “Leadership Part 1.”
Better:
Break it into 5–8 minute clips, each focused on one specific skill or story
Add a 1–2 sentence summary before each clip: “In this clip, you'll hear about how Marcus learned to stay calm in high-pressure situations.”
Follow each video with a reflection question, recap, or scenario
Why it works: Learners pause more often, engage more deeply, and feel the dopamine hit of clicking “next.”
Meh: Paste it onto one screen and say “Read this.”
Better:
Summarize key takeaways and divide into 3–5 parts
Use 100–150 words of body text per screen max
Turn complex sections into bullet lists, short scenarios, or glossary-style definitions
Add a multiple-choice or open-ended question every few screens to reinforce the point
Pro tip: If it takes you more than 2 minutes to read it, it’s too long for one screen.
Meh: Export as a PDF and upload the whole thing.
Better:
Break it into a series of short lessons or modules
Each lesson = one concept (e.g., “Goal Setting,” “Time Management,” “Building Self-Trust”)
Use visuals sparingly and always pair them with simple language
Integrate mini-assessments every few screens: “What’s one goal you’ve set and stuck with?”
Bonus tip: If the slides weren’t engaging in a live workshop, they won’t be engaging online either. Rebuild them for Edovo screens, not just transfer.
Let’s bust a few myths:
❌ It’s not just hitting “Continue” every few lines
Chunking = cognitive clarity, not formatting tricks.
❌ It’s not dumbing things down
It’s smart design that respects attention span and brain load.
❌ It’s not optional
In digital learning—especially behind walls—chunking is the delivery method. You don’t get handouts, lectures, or verbal cues. You get a screen. Make it count.
Chunking works—and we’ve got the research receipts.
Chen & Wu (2015) found that learners in multimedia environments retained significantly more information when content was presented in well-structured chunks rather than continuous streams. Breaking up video into segments of under 6 minutes led to higher comprehension and engagement—especially when paired with guiding questions or short activities.
Clark & Mayer (2016) reinforce this with decades of e-learning research: when content is divided into digestible segments and spaced with interaction, learners not only remember more, they also feel more confident and motivated. (Yes, even without confetti cannons.)
Paas & Sweller (2012) emphasize that cognitive load hits differently for adult learners—especially those re-entering education. Adults bring rich life experience, but they also face barriers like anxiety, trauma, and long gaps since formal schooling. Chunking helps balance that load by reducing unnecessary processing and letting learners focus on relevant content.
Even more importantly, adult learners benefit from immediate relevance. As Kirschner et al. (2006) caution, throwing learners into the deep end without structured guidance (i.e., without chunking or scaffolding) leads to failure—not resilience. Chunking is a key way to provide that guidance without overwhelming autonomy.
Learners retain more when content is short, focused, and spaced
Limit each screen to 1 concept, 75–150 words, or a 2–5 min task
Break long videos into clips, long texts into summaries, and decks into modules
Each chunk should end with a question, action, or pause to reflect
(Still not just here to look smart—they’re why this works.)
