- 2. Introduction The use of mobile devices in teaching and learning follows and increasing trend. In physics teaching, smartphones and tablets can be used not only as knowledge facilitators, but also as powerfull experimental tools thanks to their sensors: accelerometer, gyroscope, magnetometer, sound, light, ... Students can use their own smartphones either in teaching laboratories or in daily activities. González et al. (UVa, UFSC) Learning Physics with Smartphones TEEM'15 2 / 14

Conclusions Using mobile devices can rise interest on physics, ease its understanding and increase engagement in physics subjects, opening also the possibility of more active learning techniques. By analyzing everyday activities, the students can observe nature, test their knowledge and acquire abilities necessary in the experimental work in the laboratory. The use of smartphones as experimental tools can help building low cost laboratories and enhance learning in less favored environments. To have reliable results on the inuence on students' academic results and engagement more data are required: dierent students and conditions, more learning experiments ... González et al.
