Citizen science and inquiry learning
●Citizen science engages millions of people worldwide in scientific activities: e.g. counting birds in gardens, classifying astronomy observations
●Citizens may learn about the topic, but no change in attitudes to science or knowledge of the scientific process (Bossard, Lewenstein & Bonney, 2005)
●Inquiry learning can help people to engage in and understand the scientific process by carrying out investigations to address personally meaningful problems.
●Can we combine these?

Sense-it missions
How can you use a smartphone or tablet to:-Measure the height of a tree?-Create a noise map of your city or school? -Find whether birds are scared by city noise?-Discover whether it rains more when the atmospheric pressure is low?
-Find which is the fastest lift (elevator) in your country?

Calibration of sensors
●Eight mobile devices placed under bulb at distance of 1 meter
●Calculated illuminance: 67 lux●Actual readings ranged from 33 to 1000 lux●Mobile sensor readings may not be accurate!●Software for light sensors in older model
devices does not record continuous values
●Other sensors, e.g. air pressure, may give continuous values, but may not be accurate

User engagement
●300 users●56 missions created, 29 by users●Examples: ●Registro de la luz solar (measure the sunlight at noon over several days)●Air pressure and rainfall (does it rain when the pressure is low?)●How loud can you scream?

Evaluation
●Design-based research: identified and addressed usability issues●Engagement profiles (cluster analysis of user actions): ●Engagement profiles of ‘loyal’, ‘hardworking’, ‘persistent’, ‘lurking’, ‘visiting’●‘Volunteers with an existing bond with other members stay linked the longest;
science experts are mostly ‘visitors’●Need to help volunteers to bond, and scientists to contribute more●Engagement ended when facilitator left
●Evidence of science learning:●“I tried measuring through the window and with the window open, I got a big
difference (and yes, the windows were just washed :p ). I knew windows absorb some light but the difference was really big.” (Belgium, Record the Sunlight)
●“Belgrade has a good average. I wouldn't expect this!” (‘Germany, Record the Sunlight)
●“I wasn't aware of how a noisy neighbourhood I live!!! ;-)” (Argentina, Noise Map)
●How to create a sustainable community?
