Abstract Title: Investigating the Effectiveness of Two Instructional Interventions for Fluid Dynamics
Abstract: In this study, we compare the effectiveness of a 20-minute guided inquiry session that uses the PhET simulation "Fluid Pressure and Flow" to a twice-watched 10-minute video that integrates voice-over explanations and real life examples with recorded demonstrations using the same simulation. We will discuss the theory behind the design for these two different instructional activities and present the activities themselves. Students were assessed pre- and post-activity on a variety of questions regarding fluid speed and pressure in pipes. An additional posttest was given five weeks after the activity to assess the long term effects of this intervention. Posttest scores show that while both interventions were beneficial to students in the short term, improving their scores by an average of 18%, only the video intervention showed any significant long term improvement in student ability to correctly answer these fluid flow questions.
