Diagrams and charts are important because they present information visually. The adage “a picture is worth a thousand words” applies when it comes diagrams and charts. This handout provide a few hints on understanding information visually.

 Overview

  • Don’t skip over diagrams and graphs when reading!
  • These visual aids provide summaries or can illustrate a complex process; understanding how to read them is a very efficient way to learn material.
  • When tackling diagrams or graphs, pay attention to:
    • Captions: What clues about the illustration can you gain from the general description?
    • Labels: Can you define or describe the items labeled? If not, reread the text.
    • Directionality: Are there arrows, numbers or letters that orient the illustration?
  • The Big Picture: Do you notice any trends in data? Can you draw conclusions about relationships among items on a diagram?=

Practice

Review the two examples provided. By answering the questions for each, you’ll see how much information can be gleaned from diagrams and graphs.

Studying with diagrams and graphs

  • Start assigned readings by first reviewing any visual aids provided. This will lay the foundation for understanding the meat of your reading.
  • Review them again right before class. This will help prepare you for lecture.
  • After you have completed a reading assignment, create a visual representation that demonstrates your understanding. This active learning strategy is an effective way to transfer your new learning to your long-term memory.
