In One Teacher's Journey, Mary Groesch describes the training and experiences that molded her into the progressive educator she was for over 30 years. Likening this journey to one where a caterpillar is transformed into a butterfly, Groesch outlines her progressive philosophy through classroom narratives. One may ask after reading the book, "What would American education look like if progressive practice was the norm, rather than the traditional practice and testing culture of today?"
