Accelerated Christian Education was founded in 1970 by Donald and Esther Howard in Garland, TX, USA. A.C.E. has taken a conventionally-styled textbook and divided it into bite-sized workbooks called PACEs (Packets of Accelerated Christian Education) which are full of self-instructional activities designed to develop thinking skills and create mastery learning. In this video, the system of A.C.E. is fully explained.
