This refers to an understanding of the organizational and functional properties of written text. This encompasses knowing that print conveys meaning, recognizing the directionality of text (left to right, top to bottom), understanding the use of spaces and punctuation, and differentiating between letters, words, and sentences. For instance, a child demonstrating an understanding of this knows to start reading at the top left of a page and to follow the text across the page to the right.
Possessing this knowledge is fundamental to learning how to read. It allows emerging readers to interact with books and written materials in a meaningful way, facilitating comprehension and building a foundation for literacy skills. Its development has been recognized as a critical early indicator of reading success since research in the field began to solidify in the late 20th century, leading to targeted instruction methods.
