The Core Trio
Retention Rate
Percentage of cards successfully recalled during review.
Target: 80% - 90%
Ease Factor
A multiplier that determines how much the interval grows.
Default: 250% (2.5x)
Interval
The length of time before the next review.
Growth: Exponential
The "Ease" Lever
High Ease (>250%)
Material is mastered too quickly or is too easy. Intervals explode, potentially missing the "desirable difficulty" window.
Low Ease (<200%)
Material is significantly difficult. Cards cluster together (Ease Hell), increasing daily workload and frustration.
Calculation Engine
Inew = Iold × E
Previous Interval (Iold) 10 Days
Ease Factor (E) 250%
Next Interval 25 Days
Is 100% Good?
The 100% Trap
If a student has 100% retention, they aren't working hard enough. The intervals are too short. You are wasting instructional time on over-learning.
The <75% Danger Zone
Retention below 75% indicates cognitive overload or flawed card design. The student is guessing, not recalling.
The Sweet Spot: 85%
Balances effort with success.
Maximizes the spacing effect.
Builds self-efficacy without boredom.

Diagnosing the Persistent Failures
Lesson 2: Identifying and Fixing Memory Bottlenecks
What is a "Leech"?
The Definition
A card that is consistently forgotten after being learned. In Anki, the default threshold is 8 lapses.
The Cost
Leeches consume disproportionate amounts of time without yielding long-term retention. They are the primary cause of "SRS Burnout."
Historical Data Pattern
Review #14 Again
Review #13 Again
Review #12 Good
Review #11 Again
Why do cards fail?
Bad Design
The card contains too much information, is ambiguous, or lacks context.
Missing Foundation
The student is trying to memorize a complex fact before understanding the underlying concept.
Interference
The card is too similar to another card, causing "cross-wiring" in memory.
Surgery vs. Euthanasia
The Surgery (Fixing)
Simplify (Atomize) the content.
Add a visual mnemonic or image.
Add a personal "context" hint.
The Euthanasia (Deleting)
Delete if material is non-essential.
Suspend until foundational knowledge is built.
Re-teach from scratch offline first.

System Tuning Slides System Tuning
Customizing the Algorithm for Diverse Learners
Lesson 3: When Defaults Fail the Student
The Default Bias
Most SRS algorithms (Anki/SuperMemo) are tuned for "Average" memory profiles.
Default Ease: 250%
Assumes the student will remember the material 2.5x longer each time they succeed.
For students with executive function or working memory deficits, this multiplier is often too aggressive.
Retention Impact
!
Multiplier too high → Retention drops → Frustration → Quit
✓
Multiplier tuned → Retention 85% → Flow state → Success
Instructional Levers
Lever 1: Starting Ease
Reduce for students with lower baseline retention (e.g., 250% → 180%).
Slows down initial interval growth
Lever 2: Max Interval
Cap the maximum days between reviews (e.g., No more than 90 days).
Prevents cards from "disappearing"
Lever 3: Lapse Penalty
Adjust how far back a card goes when forgotten (e.g., 0% vs 20% of old interval).
Determines the "cost" of forgetting
The "Hard Reset"
When to clear the deck?
Review pile exceeds 500+ cards and is 2+ weeks overdue.
Significant change in medication or student status.
Foundational gaps identified that make current cards "noise".
Protocol
Resetting isn't failure; it's calibration. Reschedule reviews to 'New' and start with adjusted settings based on previous data.

The Case of Leo
Leo is an 8th-grade student with ADHD and severe working memory deficits. Using default SRS settings (250% ease), he has hit a "Wall of Reviews." His retention has dropped to 62%, and he now has 400 cards overdue. He feels overwhelmed and wants to stop using the system entirely.

Lesson 4: Turning Metrics into Motivation
The Transparency Gap
"Black Box" Learning
Student studies, forgets, and repeats. They feel like learning is random or based on "how smart they are."
Data-Transparent Learning
Student sees their forgetting curve. They understand that forgetting is a biological fact, not a personal failure.
The Goal
Move from Compliance to Agency
Student says: "I'm doing these 20 cards because I can see my retention is dipping below 80%."

Key Discussion Points:

"Your brain is designed to filter out junk. We have to prove this isn't junk."
2

3
"This graph shows you're ready for a review today."

Part 1: Translating the Curve
"When a student with executive function deficits sees a graph showing their forgetting curve, they might interpret it as 'I am failing' rather than 'This is how memory works'."
Task: Write a 3-sentence explanation you would use to explain a forgetting curve to a 10th-grade student who feels discouraged by having to review 'old' material.

The Translation Problem
Avoid "Engine Talk"
"The student has a 210% Ease Factor and an average interval of 14 days with 85% retention on a deck of 400 cards."
Outcome: Parents and IEP teams are confused and tuned out.
Embrace "Outcome Talk"
"The student currently retains 85% of their core biology vocabulary over a 2-week period without needing daily re-teaching."
Outcome: Clear evidence of long-term functional retention.

Volume
Total number of concepts successfully integrated into long-term memory.
Durability
