  • Grow readers who engage with texts — and with one another.

    When students know the words, learning thrives.

    When the words make sense, reading becomes more meaningful. When reading is more fulfilling, students tend to read more and contribute more in class. Imagine what a virtuous cycle of word learning would look like in your classroom.

We teach the whole word.

Truly learning a word means more than memorizing a single definition. teaches words by systematically exposing students to a wide array of question types, real-world examples, and activities. On, students only master a word after they have demonstrated an understanding of all of the word's meanings, and have encountered it in multiple contexts.

Our approach is particularly effective at teaching Tier II academic vocabulary words, most of which have multiple meanings.

Oasis, discovered.

Let's take a closer look at how we teach oasis. We use over 50 different questions and 10 different question types to teach both the literal and figurative meanings of the word. No one student will see every question — we choose which questions to give each student based on their overall ability level, progress towards mastery, and history with the word.

We’re not afraid to get personal.

On, each student gets their own Personalized Learning Program. Students have control over their learning program and can add words, adjust priorities, and see their progress over time.

We work with students on all the words in their learning program, and focus their energy on the words that are giving them the most trouble. While students can control the words in their learning program, words will also be added if a student struggles with words on an assignment. This ensures that students learn the words they need to know — even after you’ve moved on to the next unit.

Every student is unique — that's why we're adaptive.

We use the millions of questions answered every day on to build statistical models of how each individual learns (and forgets) new words. This allows us to identify the gaps in individual students’ vocabulary knowledge and work with students to overcome those gaps by teaching each learner differently. adapts to each student’s unique ability in three ways:

  1. We give you questions that are appropriate for you. When you first learn a word, or are learning a word that is more of a “reach” word for you, we give easier questions that provide more “scaffolding”. As you master a word, we give you harder questions that test nuance and peripheral meanings.
  2. We follow up at just the right time. We use our models to space how long we’ll wait to ask you follow-up questions on a word. As you gain knowledge, we’ll wait longer between brush-up questions.
  3. We pick words that are right for you. By comparing you to other students like you, we can predict which words you are likely to need help with (your vocabulary gaps). As we make predictions, we'll test you on these words and add them to your learning program if necessary.
