New Pictorial Representations and Supporting Text of Sound Standing Waves of Air Columns in a Tube
  Location: KFC Courts
  Date: Tuesday, Aug.02
  Time: 5:15PM - 6:00PM
  Author: Liang Zeng, The University of Texas-Pan American
  Co-Author(s): Corpuz Edgar, Chris Smith, Jennifer Rodriguez
  Abstract: New pictorial representations of sound standing waves of air columns in a tube were drawn for the first three harmonics in an open-open tube as well as in an open-closed tube. Supporting text describing air molecule motion over time was also provided. These representations and supporting text were designed to reveal the main characteristics of the physical mechanisms of sound standing waves in these two different types of tubes. Through a pilot study utilizing surveys and student interviews, we investigated the differences in the effects on student learning of underlying physics concepts between the new pictorial representations and the existing ones in an introductory physics textbook. The implications of our results for teaching were discussed.
