To achieve desired success, tutorial materials and workbooks must adequately support a good educational program. Since its founding, Daekyo has placed a high priority on the development of tutorials that reflect the underlying philosophy of the E.nopi education system. Over 200 staff members at the Daekyo Educational Research Institute are involved in research on all aspects of education and teaching that include the development of tutorials, students' diverse educational behaviors, work habits, and individual preferences. The Daekyo Educational Research Institute was founded in 1985 with a vision to emerge as a world-class research institute for the development of tutorials and other educational materials. Daekyo's development team strives to create age-appropriate problem sets for mathematics, graphical presentations of problems that can be readily understood by students globally, teaching tools and guidelines for instructors, and several other materials to support effective teaching and learning.

Without a firm understanding of child psychology and expected age-related behavior, the development of tutorials would be less student-centric than those products developed by the E.nopi educational institution.
