How to Create Effective English Flashcards
Flashcards are one of the oldest and most reliable vocabulary learning tools in existence. The principle is simple: you see a prompt on one side — a word, phrase, or question — and retrieve the answer from memory before flipping to check. This act of retrieval, not passive re-reading, is what makes flashcards so effective. Psychologists call it the testing effect or retrieval practice effect, and it has been consistently demonstrated across decades of cognitive science research.
What to write on each card
For English vocabulary flashcards, the most common format is word on the front and definition on the back. However, research suggests that richer cards produce better retention. Consider these formats:
Word + example sentence. Instead of "ameliorate: to make better", write "ameliorate" on the front and "The new policy ameliorated the working conditions for all employees" on the back. The context makes the meaning memorable and shows how the word is used in natural speech.
Definition on front, word on back. This productive recall format is harder than recognising a word from its definition, but that additional difficulty improves retention. Use this for advanced learners who want to actively produce vocabulary rather than just recognise it.
Collocations and word families. Vocabulary is not learned in isolation. A card for "make" might have collocations on the back: "make a decision, make a mistake, make an effort, make progress". Learning words in their natural combinations accelerates fluency.
Golden rule: One fact per card. If a word has multiple distinct meanings, create a separate card for each meaning. Overloaded cards are harder to learn and easier to confuse.
Spaced repetition: the science of forgetting
In 1885, German psychologist Hermann Ebbinghaus described what he called the forgetting curve: the rate at which newly learned information decays from memory over time. Without review, we forget roughly 50% of new information within an hour and up to 90% within a week. The solution is not to study harder but to study at the right moments.
Spaced repetition systems (SRS) schedule each card's review just as you are about to forget it. Cards you find easy are shown less and less frequently; cards you find difficult are shown more often. Over time, this algorithm minimises the total study time needed to maintain a vocabulary while maximising long-term retention. Popular SRS applications include Anki, Quizlet, and SuperMemo — all of which use the same underlying principle.
Even without dedicated SRS software, you can apply the principle manually. After creating your deck with this tool, study it daily for the first three days, then every other day for a week, then weekly. Mark cards you struggle with and return to them more frequently.
How to use this tool as a teacher
Teachers can create vocabulary decks for each lesson unit and share the link via Google Classroom, Teams, or email. Students click the link and the flash card exercise opens with the pre-loaded deck immediately — no accounts, no downloads, no barriers. Because the deck data lives in the URL, you can create as many decks as you need and share them at any time.
For speaking lessons, create cards with a question on the front (e.g., "What would you do if you won the lottery?") and grammar prompts or target vocabulary on the back. Students flip the card to check their answer against a model response.
How many cards to study per session
The optimal number of new cards to introduce per study session is generally 10 to 20 for most learners. Introducing too many new cards at once overwhelms working memory and reduces retention. A steady daily practice of 15 new cards with 30–50 review cards takes only 20–30 minutes and is far more effective than marathon weekly study sessions.
Focus on thematic groupings rather than alphabetical lists. A deck themed around "phrasal verbs with GET" produces better retention than a random selection because the shared context creates a rich network of associations in memory.
How to Use This Tool
- Give your deck a name in the "Deck name" field (e.g. "IELTS Vocabulary — Food & Health").
- Click "+ Add card" to add a new card row. Fill in the front (word or question) and back (definition or answer).
- Repeat until you have added all your cards — up to 20 per deck.
- Click "Generate Link" to create a shareable URL encoding your entire deck.
- Copy the link and share it via email, Google Classroom, or any messaging app.
- Anyone who opens the link will see your deck loaded into the Flash Cards exercise immediately.

Frequently Asked Questions
How does the flashcard maker work?
You enter word-definition pairs into the form, then click Generate Link. The tool encodes your cards as a Base64 JSON string and creates a URL that loads them directly into the LexFizz Flash Cards exercise. No data is stored on any server.
Can I share my flashcard deck with students?
Yes. Copy the generated link and share it via email, WhatsApp, Google Classroom, or any messaging app. Anyone who clicks the link will see your deck loaded into the Flash Cards exercise immediately — no account needed.
How many cards can I add?
The flashcard maker supports up to 20 cards per deck. For larger vocabulary lists, consider splitting them into themed decks of 10–15 cards each, which also helps with focused study sessions.
What should I put on the front and back of a flashcard?
For vocabulary cards, put the target word on the front and the definition, translation, or example sentence on the back. You can also put a question on the front and the answer on the back for grammar or comprehension flashcards.
What is spaced repetition and should I use it with flashcards?
Spaced repetition is a learning technique where you review information at increasing intervals — for example: 1 day, 3 days, 7 days, 14 days. Cards you know well are shown less often; cards you struggle with are shown more often. It is scientifically proven to improve long-term retention.
How many flashcards should I study per day?
Research suggests 10–20 new cards per day is optimal for most learners. Reviewing more than 30 new cards per session reduces retention. Consistency matters more than volume — studying 15 cards daily is more effective than studying 100 cards once a week.
Can I edit my flashcard deck after generating a link?
To edit your deck, return to the flashcard maker, update your cards, and generate a new link. The old link remains valid indefinitely as the data is encoded in the URL itself.
Is my flashcard data stored on LexFizz's servers?
No. Your flashcard data is encoded directly into the URL as a Base64 string. Nothing is sent to or stored on LexFizz's servers. The link is completely self-contained.
What makes a good vocabulary flashcard?
Good flashcards are specific, concise, and meaningful. Use the target word in a short example sentence rather than just a definition. Add context (e.g., 'formal', 'informal', 'business') on the back. Avoid making cards too complex — one concept per card is the golden rule.
Can I use the flashcard maker for subjects other than vocabulary?
Yes. The flashcard maker works for any question-answer pair: grammar rules, irregular verbs, phrasal verbs, idioms, country capitals, or historical dates. Use the front for the prompt and the back for the answer.
