Abstract Title: Effectiveness of Modified Fluid Flow Diagrams for Student with and without Prior Instruction
Abstract: Diagrams are ubiquitous in STEM. These diagrams serve a range of purposes, such as problem-solving tools, displaying data, and communicating a concept. This study investigated modifications to pressure and fluid speed gauges and their effects on students' ability to rank fluid pressures or speeds. We presented students with fluid flow diagrams for incompressible fluid flowing through pipes with varying diameters and depths. These diagrams used pressure gauges and arrows to indicate fluid pressure and speed. We modified these gauges based on theories of visual attention and affordance and investigated the effects on student responses and student learning for students with and without prior instruction on fluid flow. Findings indicate that these visually modified images were more effective than standard images for teaching students about pressure and fluid speed independent of prior student instruction. Also, we observed interesting interactions between prior instruction and student learning with the different diagram types.
