Advanced Research

Originally developed by Stanford University, our Redbird suite of offerings are uniquely positioned at the intersection of learning science and advanced technology.

Redbird was originally created to carry forward the research mission of Stanford’s Educational Program for Gifted Youth (EPGY). EPGY, a 24-year-long research project at Stanford, was dedicated to developing computer-based multimedia courses in Mathematics, Physics, English, Computer Programming and other subjects.

By combining more than two decades worth of educational science research gathered from EPGY with highly adaptive learning technology, Redbird has since evolved into a suite of learning solutions that are designed to meet the needs of all students, no matter their skill level.

The World’s Leader in Adaptive Learning

Stanford Professor Patrick Suppes, who is widely considered the pioneer of personalized instructional models, evaluated personalized adaptive learning for more than 50 years. His research proves that adaptive learning works for all types of students, ranging from the gifted to the remedial, and for students working by themselves independently, at home, or in groups at school. His award-winning research has led to accelerated learning outcomes for students across the globe, regardless of aptitude, learning environment, or demographics.

Ongoing Research

Current and planned research projects and collaborators include:


Research with senior faculty at Stanford’s Department of Mathematics drives the development of Redbird Mathematics, and efficacy studies inform further enhancements. This interdependence of foundational research and efficacy studies ensure that Redbird Mathematics will continually evolve to address the instructional needs and goals of students, educators, and parents.

Language Arts and Writing

An ongoing, multi-year research project at Stanford’s Center for the Study of Language and Information (CSLI) continues to guide the development of Redbird Language Arts & Writing. The product uses language analysis technology to evaluate more complex writing, including the identification of errors in the meanings of sentences. By looking beyond grammatical structure, this semantic evaluation technology can provide feedback on what is being expressed, not just how it is expressed.
