What Are Cloze Deletion Cards and Why They Work Better Than Regular Flashcards

·6 min read

Standard flashcards show you a term on the front and a definition on the back. They work — but cloze deletion cards take it further by forcing you to recall a word within its original context. Here's what they are, why the research supports them, and how to use them effectively.

What Is Cloze Deletion?

A cloze deletion (also called a "fill-in-the-blank" card) takes a complete sentence and hides one or more key words. You read the sentence and actively recall the missing word from memory.

Example:

Original sentence: "The ephemeral beauty of cherry blossoms draws tourists each spring."

Cloze card: "The [...] beauty of cherry blossoms draws tourists each spring."

Answer: ephemeral (lasting for a very short time)

Why Context Matters: Depth of Processing

Craik & Lockhart (1972) introduced the levels of processing framework, which demonstrates that deeper, more meaningful processing of information leads to stronger memory traces.[4] When you see a word in isolation (standard flashcard), you process it at a relatively shallow level — matching a term to its definition.

Cloze deletion forces a deeper level of processing. You must understand the sentence's meaning, consider what word fits grammatically and semantically, and then retrieve it. This contextual recall engages more of your existing knowledge, creating richer memory associations.

Desirable Difficulty

Bjork & Bjork (2011) coined the concept of desirable difficulties — conditions that make learning harder in the short term but improve long-term retention.[2] Cloze deletion is a textbook example: it's harder than simply recognizing a definition on the back of a card, but that added difficulty is precisely what makes it more effective for long-term recall.

This aligns with the broader testing effect literature. Karpicke & Roediger (2008) showed that retrieval practice — the act of pulling information from memory — dramatically outperforms re-studying for long-term retention.[1] Cloze cards maximize the retrieval demand by requiring recall in context.

Cloze vs. Standard Flashcards: When to Use Each

Use standard flashcards when:

  • • Learning brand-new vocabulary for the first time
  • • Memorizing isolated facts (dates, names, formulas)
  • • You need a quick definition lookup

Use cloze cards when:

  • • You already know the basic definition and want deeper retention
  • • The word needs to be understood in context (academic vocabulary, IELTS/TOEFL)
  • • You want to test whether you can produce the word, not just recognize it
  • • Preparing for writing or speaking sections where production matters

How to Create Cloze Cards in FlashPrep

  1. Generate standard cards first — paste your text or upload a PDF to create vocabulary flashcards
  2. Switch to cloze mode — select any card and convert it to a cloze card by choosing which word to blank out
  3. Use AI suggestions (Pro) — FlashPrep's AI can automatically suggest the best words to blank out in each sentence, based on which words are most valuable for active recall
  4. Study with spaced repetition — cloze cards are reviewed alongside your standard cards, with the SM-2 algorithm scheduling optimal review intervals

Practical Tips

  • ✓One blank per card. Clozing multiple words in one sentence increases cognitive load without proportional benefit.
  • ✓Blank the key concept, not function words. Blanking "the" or "is" teaches nothing. Blank the word that carries the meaning.
  • ✓Keep the sentence natural. Use real sentences from your study material, not artificially constructed ones.
  • ✓Combine with standard cards. Use standard cards to learn definitions, then cloze cards to practice production in context.

The Bottom Line

Cloze deletion cards aren't a replacement for standard flashcards — they're the next step. Once you know a word's definition, cloze cards test whether you can recall it in context, which is closer to how you'll actually need to use it on exam day. The extra difficulty is the point: it's what makes the memory stick.[3]
