Spaced Repetition Flashcards for ESL Students

Edooqoo creates spaced repetition flashcards for ESL students using the SM-2 algorithm. Teachers generate flashcard sets from worksheet vocabulary with one click or create cards manually. Students study through the Student Hub portal with optimized review intervals for maximum vocabulary retention.

Spaced repetition is the most scientifically validated method for long-term vocabulary retention. The SM-2 algorithm (SuperMemo 2) calculates optimal review intervals based on how well a student remembers each word. Words that are difficult are reviewed more frequently; words that are easy are spaced further apart. This maximizes learning efficiency.

Unlike standalone flashcard apps (Anki, Quizlet), Edooqoo's flashcards are integrated into the teaching workflow. Vocabulary from worksheets flows directly into flashcard sets. Flashcard performance feeds into the DSLM progress tracking. Teachers see which vocabulary students retain and which needs re-teaching.

Frequently Asked Questions

What is SM-2 algorithm?

SM-2 (SuperMemo 2) is a spaced repetition algorithm that calculates when each flashcard should be reviewed. It tracks an "easiness factor" per card — easy cards are shown less frequently, difficult cards more frequently. This optimizes study time and maximizes retention.

Can students study on their phone?

Yes. The Student Hub and flashcard interface work on any device with a web browser — smartphone, tablet, or computer. No app installation needed.

Can I see what my students are studying?

Yes. Teachers see flashcard sets per student, review statistics, and vocabulary mastery levels. The DSLM integrates flashcard performance into overall progress tracking.

Can I create flashcards without worksheets?

Yes. You can manually create flashcard sets and add individual cards with front text, back text, and optional example sentences. This is useful for ad-hoc vocabulary practice outside of lessons.

Is bidirectional study available?

Yes. Students can study cards in both directions — seeing the word and recalling the definition, or seeing the definition and recalling the word. This strengthens both recognition and production.
