iNaturalist is a web site, and an app, for sharing pictures and observations of plants and animals. Thanks to Richard Byrne at Free Tech for Teachers for posting!
"CCL4s provides an interface for entering observation data as well as access to all the Content Standards for Mathematics K-12 and the ISTE NETS.S. The collected observation data can be shared via email or with our unique built-in instant meeting. The graphs are very interactive and allow observers to merge different observations to compare and contrast different teachers or the same teacher over time. Using the Timeline feature, observers can track the observed Look-fors through time."
This product from the School Improvement Network facilitates administrative classroom walkthroughs in that it leverages the camera capabilities of the iPad/iPhone/iPod Touch and integrates it with assessment tools designed to give teachers constructive feedback.
Though this version of the app doesn't have as many features, it's free! With an iPhone or iPad, students can create time lapse recordings so as to improve observational skills, document a laboratory, or create a digital story.
