Quill (Empirical) is a nonprofit developer of free, interactive learning tools. Their mission is to make students active players in their education by presenting students with problems to solve and allowing them to construct solutions. In this environment students take charge of their own education. They support students, teachers, and parents. Teachers can sign up their classes and monitor their students' progress. They are currently working on parental accounts so that parents can receive report cards on their students' progress. They currently support middle school students studying English. They cover all of the grammatical concepts from the Common Core State Standards for grades 1-8. They intend to expand our coverage to high school students, college students, ESL students, SAT / ACT students, and foreign language students.
