Concept-Based Tracking

Traditional apps track which sentences you've completed. But completing a sentence doesn't mean you've learned its components—and what happens when the content updates?

What It Is

Concept-based tracking means the system monitors your knowledge of underlying concepts—individual words, grammar patterns, structures—not just surface-level phrases. When you practice "the cat is sleeping," your exposure to the word "cat," the present progressive tense, and the verb "sleep" all update separately.

Why It Matters

A single phrase teaches multiple concepts at once. When you later encounter "the dog is running," the system knows you already have a foundation in present progressive, even though you've never seen that exact sentence. Your progress compounds across everything you learn.

This also means your progress is durable. If we update the curriculum—add phrases, reorganize levels, improve content—your underlying concept knowledge remains intact. You're not starting over because a sentence changed.

What Goes Wrong Without It

Apps that track phrase completion create fragile progress. You "finish" a lesson, but the system doesn't know which specific concepts you've actually learned. If you struggle with a sentence, it can't tell whether the problem is vocabulary, grammar, or something else.

Worse, progress in these systems often resets when content updates. Your "completed" lessons become invalid, and you're asked to redo material you already know.

How The Method Implements This

Every phrase is decomposed into its constituent concepts: vocabulary, grammar patterns, structures. When you practice, each concept's exposure count and timing updates independently.

The system knows that "the cat is sleeping" and "the dog is running" share present progressive. If you've seen progressive verbs many times across different phrases, the system spaces out future exposures. If you've only seen "cat" once, it comes back sooner.

Each concept also has a difficulty rating. Simple vocabulary needs fewer repetitions than complex grammar. The system handles this automatically.

This same architecture powers recall exercises. When you attempt to produce a phrase on your own, your self-assessment updates the confidence of every concept in that phrase—the individual words, grammar patterns, and structures. A single recall attempt on "the cat is sleeping" adjusts your tracked confidence in "cat," "sleep," and present progressive simultaneously. This means recall results compound across your entire learning history, just like phrase exposure does.
