No, It’s not an arch-villain from a comic book...

...The Shuffler is a tool your language learners will come to love.

Every learner is unique - just like every DynEd course. Our content is multi-layered with varying degrees of language complexity, even within a lesson. The Shuffler allows us to personalize the learning experience. Each learner has different life experiences with English learning, and we don't want to bore learners with what they have mastered already.

When the Shuffler detects mastery of concepts, it makes the content more complex. Likewise, when the Shuffler detects the learner is being challenged by new concepts, the Shuffler eases up the difficulty level. This constant adjusting of content ensures that the learner is neither frustrated nor bored. It's why students will spend hundreds of hours mastering their English skills in DynEd courses and how we make their time perfectly challenging and interesting.

While the Shuffler quietly and seamlessly goes about its job of adjusting the content, our system is analyzing the study data and providing the learner with automated Tutor messages. For more information about how DynEd uses big data, see How we do it.
