Marie Clay Principles of writing development
Described children's interactions with the writing in books and their imitation of this - principles of development.
Recurring principal - when a child only knows a limited number of letters repeatedly use these to create a message.
Directional principal - reading and writing from left to right, using a return sweep to start the process again.
Generating principal - realise there are only a limited number of letters to use, but that these can be met mixed and matched in different ways.
Inventory principle - begin to package knowledge, together into list of the letters and words that he or she knows.
