Survey123 (http://survey123.esri.com) is a powerful technology for field data collection. As of this post it is still in Beta, but it is sufficiently stable and robust to deserve attention by educators. ((Updates in the last week solved some key issues.)) Watch even just the first 7 minutes of the intro video (on YouTube), and you'll get a sense. The power of the app comes from designing a well-tuned survey using a spreadsheet -- something every educator should be able to do. Even more powerful: kids can build these, with PCs, Macs, Chomebooks, and tablets.
The first challenge in any project is figuring out the mission; the second challenge is figuring out how to meet the mission. I've crafted a simple survey that meets both challenges quickly, for any school with an ArcGIS Online Organization. (K12 schools in the US should see http://www.esri.com/connected.) The survey attached to this entry lets educators ask students some "non-invasive" questions, in English or Spanish. After seeing the Survey123 video linked above, it helps to do a survey, and then study how the survey was built, before thinking about building one's own. This survey uses some tricks that would be important in schools but are barely mentioned in the video or help file -- setting up a second language, making the feature service build itself in the default language, crafting responses that need e.g. exactly 3 alphanumeric characters or 5 numbers, and so on.

I look forward to comments!
