Textmapping is a graphic organizer technique that uses colored markers and mapping to visually represent the organization of a text. It focuses on pre-reading and highlighting key elements like headings, keywords, and subsections. Teachers say it helps struggling readers comprehend texts by making the structure and organization explicit. It is particularly helpful for visual, kinesthetic, and global learners. The process involves identifying relevant text features and marking them on a graphic to create a visual record of understanding.
