Social Learning for Your Class

Are you an educator looking for a simple collaborative, adaptive learning solution? Brainscape allows teachers and professors to create a "flipped classroom" in minutes. You can either:

  1. Make your own flashcards to share with your students (and encourage students to suggest edits & improvements); OR:
  2. Have students collaborate to create the flashcards together.

Students can study their adaptive flashcards online or in the Brainscape mobile app, and all their progress is kept in sync across devices.

And from your Teacher Dashboard, you can easily see how much your students are studying, and which topics students need the most help on.

Proven Cognitive Science

Brainscape works by guaranteeing that each concept is repeated in just the right of time for your brain’s maximum benefit.

As you rate your confidence in each flashcard, on a scale of 1-5, our Confidence-Based Repetition™ learning system optimizes your personal study stream, helping you learn more than twice as fast and retain information for longer.

This unique application of spaced repetition combines the key mental activities of Active Recall, Metacognition, and Spaced Repetition more effectively than any other learning tool. Each step of the Brainscape learning process activates your hippocampus to maximize the strength of new neuron connections in your prefrontal cortex.
