The Idea-Map is a specialized set of graphical organizers. Like all other graphical organizers, these tools help students produce visual representations of the main concepts of a document.
The Idea-Map is unique because of its simplified form. Compared with other (more exotic) graphical organizers, Idea-Maps are relatively simple block charts that represent a document's progression of ideas in vertical (top to bottom) or horizontal (left to right) fashion.
Lenski, Wham, and Johns (1999) describe four types of Idea-Maps:
The Enumeration (Description) Idea-Map prompts students to identify main ideas and list possible definitions, related terms, or examples.
The Compare and Contrast Idea-Map asks students how two related concepts are alike and different and then to chart these comparisons on a Venn diagram.
The Time Order or Sequence Idea-Map helps students uncover the logical progression of ideas in a documentfrom earliest to latest, from most to least important, etc.and, then, to place specific items or details within this sequence.
The Problem and Solution Idea-Map allows students to investigate and analyze possible solutions to problems.
