http://www.polleverywhere.com/ in my Web 2.0 tool. This tool allows immediate live 100% audience participation during presentations using phones, laptops or tablets to text a response. Each poll allows 40 responses for the free version. It works with any mobile device including flip phones that can be used to send texts. Responses can be both multiple choice, true/false and/or open ended. Once you've created polls with a correct answer, you run a report to calculate how each respondent scored - and how they rank in terms of correct responses and average time to answer correctly. Polleverywhere can be used to take attendance, take a quiz, vote, take participation grades, or for individual or team competition. This tool can be embedded in Power Point or Keynote. Polleverywhere is free but can be upgraded if needed to a paid account.
I learned to use the "Bump" app to download my contacts, files and photos from an Android smart phone to an Apple iPHONE 5c. I was told that since Android and Apple products could not be blue-toothed and it was not possible to move the information between the two without using cloud storage. However, the app "Bump" makes the transfer between the two possible. Yeah!
