This writing workshop term refers to the period before beginning a unit of study when a class explores several examples of texts within a genre. 

 

During this time, teachers and students read and enjoy these books interactively as readers. After the stories have been shared, they may be studied and read like a writer for the purpose of gaining a better understanding of how texts within a given unit of study are crafted.
  

Immersion is an important phase of each unit of study because it helps children understand how different types of writing are constructed and how they are meant to sound.
