Matt, a fellow Google Certified Teacher, recently did a Hangout with Rebecca Vierya. Rebecca and Matt met at the Austin Google Teacher Academy and she shared some of the Android software she and her husband developed to tap into all of the power that phones and tablets possess but isn't easily accessed for learning.
The Vierya's free Suite of Tools at Google Play is simple to use and contains the following apps:
- G-Force Meter - ratio of Fn/Fg
- Linear Accelerometer - acceleration
- Gyroscope - radial velocity
- Barometer - atmospheric pressure
- Roller Coaster - G-Force Meter, Linear Accelerometer, Gyroscope, and Barometer
- Proximeter - periodic motion and timer
- Hygrometer - relative humidity
- Thermometer - temperature
- Magnetometer - magnetic field intensity
- Light Meter - light intensity
- Sound Meter - sound intensity
- Tone Generator - frequency producer
- Orientation - azimuth, roll, pitch
According to the developers, "Useful for education, academia, and industry, this app uses device sensor inputs to collect, record, and export data. in comma separated value (csv) format through a .txt file sent via an e-mail or through Google Drive. All analog data is plotted against elapsed time (or clock time) on a graph. Users can export the data for further analysis in a spreadsheet or plotting tool. The app also allows for a tone generator output."
Through the user interface a number of the sensors can be used together for all kinds of different explorations of math and physics concepts in the real world.
On her own site, Rebecca has compiled a ton of links where the tools have been referenced at all levels of academia from elementary schools to higher education.
