Google does it again! Yesterday, they announced the creation of forms on Google Docs to allow for quick, easy input of data into a spreadsheet. You can create a form for what info you want and share the form. The form can be sent out as an email, but we have found there are still some kinks with filling it out in the email. However, using the link, you can have people enter their data and it will automatically fill in on your Google Spreadsheet for all to see!
This could be a great tool for in the classroom. Imagine being able to use the data from an experiment run earlier in the day? You can get a better sample space to work with to analyze data. My science and math teachers will love this! Check it out and play around.
