Introduction

The use of mobile devices in teaching and learning follows and increasingtrend.

In physics teaching, smartphones and tablets can be used not only asknowledge facilitators, but also as powerfull experimental tools thanks totheir sensors: accelerometer, gyroscope, magnetometer, sound, light, ...

Students can use their own smartphones either in teaching laboratories orin daily activities.

Our work

• Developing apps:• Learning apps with theory, examples, tests, simulations, ...• (learning) Apps to use the smartphone as an experimental tool.

• Thinking on how to use the smartphone in laboratory or everydayactivities experiments.

Other experiments in everyday activities:

Traveling from home to the university

Di�erent sensors: The students canmeasure simultaneously accelerations,light and sound intensities, magnetic�elds, position, etc.

Analysis: Dependences, repeatability,experimental noise, ... all of themcharacteristics of the scienti�cexperimental work.

Conclusions

Using mobile devices can rise interest on physics, ease its understandingand increase engagement in physics subjects, opening also the possibility ofmore active learning techniques.

By analyzing everyday activities, the students can observe nature, test theirknowledge and acquire abilities necessary in the experimental work in thelaboratory.

The use of smartphones as experimental tools can help building low costlaboratories and enhance learning in less favored environments.

To have reliable results on the in�uence on students' academic results andengagement more data are required: di�erent students and conditions,more learning experiments ...
