Resumen: An educational variable‐rate application (VRA) sprayer was developed and laboratory tested at the University of Seville (Spain). It was designed and built during 2009 by the undergraduate engineering students in a Precision Agriculture course and used as a teaching model in an Agricultural Machinery course during 2010. The first stage involved mounting all the instrumentation, sensors, and the hydraulic system on a metal platform. The second stage involved mounting a DGPS receiver, flowmeter, automated application control system, and all necessary electrical connections to the platform. Preliminary calibration tests of the equipment at a constant speed of 0.375 m s‐1 (1.35 km h‐1) showed good performance for pressure (kPa) and application rate (L ha‐1) (R2 = 0.998, p < 0.001). To evaluate the teaching method based on the prototype, a short‐answer assessment test was conducted consisting of ten multiple‐choice questions, each with one possible correct answer. Data were analyzed...
