Moby Vocabulary is the fastest way to learn new words and ensures that students remember words for a lifetime. With Moby's adaptive pretest, students are presented with only the words they are not familiar with, allowing them to focus their efforts on learning new words. After learning a new word, students have the opportunity to practice its meaning by matching it with the appropriate definition, sentence, and picture. Moby Vocabulary's review cycle then ensures that the new vocabulary words are retained long-term.

Teachers have the flexibility to begin Moby Vocabulary with a pretest to assess each student's current word level, or manually set their level themselves. They can then choose to let Moby find the words the student is unfamiliar with or create their own customized word lists. Regardless of the method chosen, Moby Vocabulary's effective Find-Learn-Practice-Review cycle ensures efficient and lasting learning.
