Ultrasound motion detectors and associated computer software have been widely used to help students learn concepts related to motion and graphing. Associated software provides a rich set of representations and spontaneous calculations (e.g., velocity, acceleration). However, multiple representations do not necessarily lead to scientific understanding. Without practicing the transformations among multiple representations, students may not develop the scientific habit of mind of systematically organizing their knowledge. In this Walking Out Graphs lesson, students experience several types of representations used to describe motion, including words, sentences, equations, graphs, data tables, and actions. The most important theme of this lesson is that students have to understand the consistency among these representations and form the habit of transforming among these representations.
