According to Wilhelm von Humboldt (1767), humans seek to "seize as much of the world as possible, and connect with it as closely as can be done". Reading, writing, speaking, and listening are the keys to different worlds. Through literacy skills one doesn't only receive access to a wide variety of environments, but also the opportunity to express oneself and to communicate. Written language is a basic cultural skill, and its acquisition requires very fundamental capabilities that are necessary to be able to encode letters, mentally convert them into words and vice versa, to translate words into letters, and to produce them on paper (or another medium).
Written language acquisition therefore does not begin with the writing of letters or whole sentences, but instead with simple movements that mimic writing, which children already practice in preschool. From the first doodles, through mastery of the alphabet, to perfection of spelling and expression, is a long, arduous, extremely interesting, unbelievably important and highly complex process, which children undergo with a wide variety of requirements and in a variety of ways.
We want to understand this process for all children, and to support the view that many paths can lead to the same goal, also in school.
