Take a poll of the students in class: How many have used a computer or Internet based intervention? How many have used a mobile health app? How many have played a health video game? How many have used social media for health? Divide the class into small groups based on their participation experience: Try to have one group for each major category. Have the groups discuss their experiences and then report back to the class. Are there similarities or differences across their experiences by category (e.g., mobile app versus game)?
