Five main types of organizers
Graphic organizers are valuable instructional tools. Unlike many tools that just have one purpose, graphic organizers are flexible and endless in application. One common trait found among graphic organizers is that they show the order and completeness of a student's thought process - strengths and weaknesses of understanding become clearly evident. Many graphic organizers show different aspects of an issue/problem - in close and also the big picture. Since many graphic organizers use short words or phrases, they are ideal for many types of learners, including English Language Learners with intermediate proficiency.
Although five main types of organizers are mentioned in this piece, many others exist, or will soon be created. See examples below.
