• Resumen

  • Smartphones are already taking part of the everyday life of more than two and a half billion people. University students are one ofthe population groups in which smartphone penetration is more intense. Applications for activities organization, voting,translation, information sharing, flashcarding, etc. are already of general use. However, despite the considerable big number ofavailable data acquisition and analysis applications, few learning activities take advantage of the smartphone physical interfacingcapabilities (accelerometers, gyroscopes, magnetometer, microphone, camera, flashlight, loudspeaker), which, due to the presentcomputing power of smartphones, are excellent. This leads to infer that smartphones could be a relevant tool for enhancing theteaching-learning process in technical studies. Students attending to engineering careers are an especially adequate target forsmartphone aided teaching due to their training in the use of computers and other electronic equipment and their strong previousknowledge in fields as programming or quantitative data management. In this work, the data acquisition capability of smartphonesis studied, different teaching-learning activities based on this capability are proposed, and the impact of the introduction of threerepresentative smartphone-based learning activities, as balancing of shafts, evaluation of stick-slip instabilities or machine acousticpower measurement, is analyzed.
