Spaced Repetition Foundations: Build Your Deck and Review Schedule

By Better Wise

Lesson 1.1: Spaced Repetition Foundations

This is where the whole course starts. Before shadowing drills, before survival phrases, before sitting in an international team meeting, you need a way to stop new words from sliding out of your head. That is what a small deck and a boring daily habit give you.

By the end of this lesson you can:

• Explain in one sentence why reviews spread over time beat studying once
• Design a card that tests exactly one thing
• Build a starter deck of 10 to 20 cards
• Set a 10 to 15 minute daily review slot that survives a busy week
• Spot and repair a card that keeps failing

Why Spacing Beats Cramming

I once learned 200 travel words the night before a trip. By the airport I had maybe 40 left. My brain had not failed me; I had simply asked it to hold everything in one go, with no second chance to pull the words back out.

Your memory decays in a predictable curve, fast at first, then slower. The trick is not to reread a card while the word is still fresh. It is to recall the answer right around the moment you are about to forget it. Every successful effortful recall bends the curve flatter, so the next gap can be longer. That single idea is all spaced repetition means: the same item, at growing gaps.

Two consequences follow, and beginners get both wrong:

1. Reading the answer and thinking "yes, I knew that" does almost nothing. You must produce the answer first, then check.
2. A failed card is information, not a punishment. It tells you the gap was too long, or, more often, that the card was badly written.

Note: Active recall is the engine, spacing is the accelerator. A perfect schedule with passive rereading still leaks words.

Exercise 1: Diagnose the habit

Three learners describe their evening. Which one is doing spaced repetition, and why?

• Mara: rereads a 60-word list every night before bed.
• Tomas: reviews 12 cards, saying the answer out loud before flipping, and skips what is not due.
• Priya: reads the whole deck on Sunday for an hour, then nothing all week.

Tomas. He produces the answer before checking (active recall) and works only the cards that are due (spacing). Mara is rereading passively, so recognition feels like knowledge. Priya has massed her practice into one block, which is the opposite of spacing, and she also gets no daily contact with the language.

Building a Deck You Will Actually Finish

A beginner deck should be tiny and sharp. Ten to twenty cards is plenty for week one. Here are the card rules I use, learned after years of building 900-card decks I abandoned in March.

One card, one fact. If the back of your card has three translations, split it into three cards. You cannot recall a bundle as one unit.

Front = a cue with exactly one answer. "House?" is a weak cue, because casa, maison, huone and dom all want to jump out. "Spanish for house?" is a cue.

Back = the answer plus one small hook. A hook is a sound, a memory, a person. "Casa, sounds like castle, both are places you live." Hooks are personal and often silly. Keep them.

Use sentences early. A word card stores a word. A sentence card stores the word with its grammar and its usage: "¿Dónde está el baño?" teaches the question pattern, not just the noun. Once you can hold a sentence, add those.

Keep the deck honest. If you fail a card three reviews in a row, it is a leech. Do not review it harder; rewrite it smaller or delete it. A leech is a design problem, not a memory problem.

Exercise 2: Repair three bad cards

Rewrite each of these so it follows the rules above.

1. Front: "Train" / Back: "tren, train station, ticket, platform"
2. Front: "What is the Japanese word for the polite way to say thank you when someone hands you something? Give the casual and formal form and when to use each." / Back: a paragraph
3. Front: "おはよう" / Back: "good morning"

1. Split into four cards. One example: Front "Spanish for train?" Back "tren".
2. Too much on one card. Cut it to: Front "Japanese: the everyday thanks when someone hands you something" Back "どうも (dōmo), casual but polite".
3. This one is close to fine, but the back should carry a hook or context: "good morning, used until about 10 or 11 a.m., sounds like Ohio plus gozaimasu later."

A Review Schedule That Fits a Real Day

Most apps handle intervals for you. You still need to know what the numbers mean, because you will be tempted to override them. A common beginner curve looks like this: a new card returns after 1 day, then 3 days, then 7, then 14, then 30. Each success pushes the next gap out.

The habit matters more than the algorithm. Pick a fixed 10 to 15 minute window that already exists in your day: the kettle boiling, the metro ride, the queue at the bakery. Same slot, every day. Ten minutes daily beats a heroic Sunday.

Two rules keep this alive. First, clear the queue before adding new cards; if reviews are piling up, stop adding. Second, a missed day is not a restart. Open the deck, work what is due, move on. It is a missed day, not a failed system.

Exercise 3: Write your week

Choose your daily slot and write it into your calendar now, as a repeating event. Then decide your cap: for example, maximum 15 new cards per week, reviews first. Reply to yourself in one sentence: where, when, how long.

Your answer is correct if it names a time, a place cue, and a duration under 15 minutes.

The point of a review is to _____, not to reread the card. A well designed card tests exactly _____. A new card usually comes back for its first review after about _____. A card you fail three times in a row should be _____ rather than drilled harder. Ten focused minutes _____ beats one long session per week.

Mistakes I Made So You Don't Have To

• The collector's trap. Adding 40 new cards a day feels productive and buries the reviews that actually teach you. Cap new cards weekly.
• Rereading instead of recalling. If your eyes move over the answer before your mouth does, you are studying, not reviewing.
• Skipping the hard cards. The two cards you dread are the two doing the work. Do them first.
• Perfect decks. Rewriting cards for color and order is procrastination with extra steps. Ugly decks get learned.
• No speaking. Say every answer out loud. The mouth learns faster than the eye, and it is the organ you will use on the trip.

Front: What is spaced repetition? Back: Reviewing the same item at growing gaps of time.

Front: Why does spacing beat cramming? Back: Each effortful recall at the edge of forgetting strengthens the memory more than rereading does.

Front: What is active recall? Back: Producing the answer from memory before you check it.

Front: How many facts should one card test? Back: Exactly one.

Front: Typical first review gap for a new card? Back: About one day.

Front: What is a leech card? Back: A card you keep failing, which usually signals bad card design.

Front: What should you do with a leech? Back: Rewrite it smaller or delete it, do not drill it harder.

Front: What belongs on the front of a card? Back: A cue that has exactly one correct answer.

Front: Why split a card with several translations on the back? Back: You cannot recall a bundle as one unit.

Front: Why add sentence cards early? Back: They store a word with its grammar and real usage.

Front: Best daily review dose for a beginner? Back: 10 to 15 minutes in the same slot each day.

Front: Reviews are piling up. What do you do about new cards? Back: Stop adding them and clear the queue first.

Front: You missed two days. How do you restart? Back: Open the deck, work what is due, keep going. No reset needed.

Pocket Takeaways and What Comes Next

You now have the two things this course needs from you: a deck of small, single-fact cards, and a daily slot short enough that you will not negotiate with it. Spacing is not a study trick, it is a way of being honest about how memory works.

Your cards give words a place to live. In the next lesson, Active Listening and Shadowing Drills, you will build the other half: ears and mouth, so the words you review start coming out with the right rhythm.
