The 21 Principles: Inspire to Learn (A Teacher's Journal) is a series of informational learning tools developed and designed to assist teachers with classroom management through activity planning. The 21 Principles was developed and implemented during author and teacher Morgan Punkston's fifteen years in the classroom through a desire to improve and promote her students' studies. Morgan's teaching principles were first introduced in the middle grades and have proven to be highly adaptable in high school and adult education classrooms. With The 21 Principles: Inspire to Learn (A Teacher's Journal) , other educators have a powerful opportunity to "Grow from a zero to a hero," just as Morgan did in her highly rewarding teaching career.
