Why Johnny Can't Read—And What You Can Do About It is a 1955 book-length exposé of American reading education by Rudolf Flesch. It was an immediate bestseller for 37 weeks and became an educational cause célèbre.^[1] In the book, the author concluded that the "(look-say)" method (memorization of whole words by sight) was ineffective because it lacked proper phonics training. Additionally, Flesch was critical of the simple stories and limited text and vocabulary of the Dick and Jane style readers that taught students to read by memorization of words.^[2] Flesch also believed that the look-say method did not properly prepare students to read more complex materials in later grade levels.^[3][4]
