Annotating text involves adding purposeful notes, keywords, phrases, definitions and connections to sections of text. It promotes student interest and engagement by giving them a focused purpose for reading and writing. Annotating helps students clarify ideas, ask relevant questions, and develop analytical thinking about the text. The purpose of annotation is defined based on learning targets, and students are taught to annotate by highlighting key parts of text and writing notes to explain their relevance. Annotating causes deeper processing of information and increased recall.
