Re-reading your notes the night before a test feels productive, but it barely helps you perform better the next day. And even when it does help, you might ace the quiz on Friday and remember almost nothing by Monday. That's not a personal failing โ€” it's just how the brain works when you study the wrong way. The good news? The same research that reveals the problems also reveals the solutions. Here are key principles we build every course around.

Principle 01
Your brain remembers what it has to think about
Deep Processing

Think about everything that happened to you today. You can probably recall a surprising amount of it: a conversation that caught you off guard, a decision you wrestled with, something that annoyed or pleased you. None of it was on a study list. You remember it because you actually thought about it, reacted to it, connected it to your life. That's deep processing happening naturally.

The more mental effort you invest in engaging with something โ€” analyzing it, questioning it, connecting it to your own life โ€” the more processing occurs and the more firmly it gets stored in your long-term memory. Shallow tasks, like highlighting and re-reading, feel like studying but barely move the needle.

How we apply it

Our Alias Learning Engine asks questions that require students to actually think: apply an idea, evaluate a claim, connect something new to something they already know. It doesn't ask them to memorize. The more mental work a student does with a piece of information, the more securely it sticks.

Principle 02
Memory is a web, not a filing cabinet
Elaborative Encoding

Your brain doesn't store facts in separate folders. It stores them as a web of connections to other ideas, experiences, images, and emotions. The more connections a memory has, the more firmly lodged it is in memory and the easier it is to retrieve later.

For instance, a Civil War battle means more if you've visited the town where it was fought, or if you've seen the movie. A statistics formula sticks better once you've used it to figure out whether a headline is lying to you. Researchers call this elaborative encoding: the brain holds onto information more firmly when it's tied to something real, not floating in isolation.

How we apply it

At enrollment, students fill out an interest survey. Our Alias Learning Engine uses those answers to pull in examples and analogies that are actually relevant to each student. The connections between new material and real life aren't generic, they're personal. That's what makes them stick.

Principle 03
Spread it out โ€” don't cram
Spaced Practice

One of the oldest and most reliable findings in learning research goes back to the 1880s: studying something once for four hours is far less effective than studying it for one hour across four separate sessions. The brain consolidates memories during the gaps between study periods, especially during sleep.

What makes this especially powerful is timing. Returning to material just as you're starting to forget it forces your brain to work to retrieve it, and that effort strengthens the memory each time. You also associate the information with different contexts each time you study it, which makes it easier to recall in different situations later.

How we apply it

Our Alias Learning Engine brings back material from earlier in the course at regular intervals, just often enough that students have to work to retrieve it, but not so often that it becomes rote.

Principle 04
Testing yourself is the best way to study
Retrieval Practice

Trying to remember something is more powerful for learning than re-reading the material. When you struggle to pull information out of memory, even if you get it wrong at first, you strengthen that memory far more than when you passively review notes.

Researchers call this retrieval practice, or the testing effect. It's one of the most consistently replicated findings in learning science, and yet most students use passive review as their main form of studying.

How we apply it

Each module in each class builds on what came before, so students are constantly drawing on earlier material to make sense of new concepts. They have to dig it out of memory or look it up, and both strengthen learning.

Principle 05
You don't always have to try to learn
Incidental Learning

Deep processing happens whenever you're genuinely engaged with material, whether or not you're trying to learn it. When something is meaningful or interesting, the brain processes it deeply on its own.

You can walk out of a film and reconstruct the entire plot, the characters, the ending, without having tried to learn any of it. The movie held your attention, so your brain did the work. Researchers call this incidental learning. Courses designed around material students actually find interesting produce durable knowledge without the grind of forced memorization.

How we apply it

Every course builds toward a project that asks students to apply what they've learned to something they actually care about. The projects are designed to be inherently rewarding, not just assigned work. When students are genuinely invested in the outcome, the learning that leads to it tends to stick.

Principle 06
The sweet spot: not too easy, not too hard
Zone of Proximal Development

In the 1930s, Lev Vygotsky argued that learning happens in a narrow band just beyond what a student can already do, but within reach with some guidance. He called this the Zone of Proximal Development.

Work that's too easy produces little growth. Work that's far too hard leads to frustration and shutdown. The sweet spot is right at the edge of what a student can currently do, where the effort is real but success is achievable.

How we apply it

Our Alias Learning Engine tracks each student's progress and adjusts the difficulty of each interaction accordingly. Every student works at their own edge, not the class average.

See it in action.

The best way to understand how this feels from a student's perspective is to try a lesson yourself.
