Empirical Grammar is personalized grammar lessons. Students proofread essays laden with errors and then receive personalized homework.
Empirical is a not for profit developer of interactive knowledge. Interactive knowledge is knowledge gained through experience. There is a significant problem in digital education today. Publishers tend to equate watching videos with learning. This is a problem because we retain very little of what we are told, but we retain far more of what we do ourselves. At Empirical we create problem sets for students to interact with and solve.
