Lucida for teachers

At a glance

Why flashcards work in school

Retrieval practice means asking students to recall what they learned instead of rereading it, and research in schools supports it. In three experiments with sixth graders, low-stakes quizzes raised scores on chapter and semester exams (Roediger and colleagues, 2011). The retrieval practice guide from Agarwal and colleagues advises keeping it low-stakes or no-stakes, doing it often, spacing it out, and giving feedback. Flashcards and live games show the answer right after each try, and Lucida’s schedule spaces the reviews for you.

Run a unit, step by step

• 1. Make the deck. Type cards, import them, make cards in Lucida from your slides, or ask your own AI to draft cards. Lucida shows the cards it makes before they are saved, and with your own AI you can turn on Let me check AI cards first, so you read them before students do.
• 2. Share it by link. Open the deck’s settings, choose Sharing, pick Link only (or Public), and post the link where your students look.
• 3. Let students study it. They sign in, then study the deck as it is or make a copy of their own. Their schedule, streak and scores stay theirs and never go to you.
• 4. Use Live for review days. Open a room from the deck on your computer, show the code on the big screen, and students join on their phones.
• 5. See the hardest cards (Pro). On a deck you share, Pro shows which cards people miss most, as percentages without names.
• 6. Improve the deck. Students can suggest fixes. You take or skip each one, and everyone studying the deck gets the update.

Live games for review days

From any deck of yours, choose Play live, pick how many questions (5, 10 or 20) and the time for each (10, 20 or 30 seconds), then open the room and show the 6-digit code on the big screen. Students go to lucida.cards/join on their phones and type the code and a name. A room holds up to 60 players, and players need no account.

Everyone answers the same multiple-choice questions for points, and a leaderboard follows each question. Live games aren’t graded and don’t save a report, so keep the points for fun. You can also start a game from a topic you type, which counts as one of your daily makes. See live games.

Privacy and student data

• Students must be 13 or older. Lucida’s terms require it, and its privacy policy says it isn’t meant for younger children.
• When students study your shared deck, their schedule, streak and scores never go to you.
• Lucida’s privacy policy says it shows no ads, doesn’t sell your data, and doesn’t use cards to train AI models. Supabase stores the data in the United States, and students can export or delete it.
• When you make cards in Lucida, the text, pictures or audio you add go to an AI service to write the cards. Lucida asks for services that say they don’t keep it or train on it.
• People who join a live game give a name and nothing else: no account and no email.
• The privacy policy doesn’t mention school-specific privacy laws, so check with your school before you use Lucida with students.

Verified teachers

Teachers can ask to be verified, in Settings, with a school email or a link that shows where they teach. The Lucida team reviews each request. A verified teacher gets a check on their profile and can mark shared decks as Checked, which shows a badge until the deck changes. Discover has a Checked by teachers section. The badge means one teacher checked the deck, and it isn’t a guarantee. See shared decks.

What Lucida doesn’t do for teachers

• There’s no gradebook, roster import, or link to school systems.
• You can’t assign a deck to students or set a due date.
• There are no per-student answer reports. On Pro, you can see which cards on a deck you share people miss most, as percentages without names.
• Live games aren’t graded and don’t save a report.
• Lucida isn’t for students under 13.
• Everything needs an internet connection.
