Signing up your teachers with a Google Form
Create a google form like this one that will allow your teachers to share what they plan to do when they visit your library. This kind of form can be easily adapted to your own use. (NOTE: Don't submit on the WJHS form. Instead, visit templates here or here and make your own.) Data is collected into a spreadsheet inside of your Google Docs account. Even if your teachers are reluctant to fill it out, you can use it yourself!
(You can also use this idea to create a "follow-up" form: [LINK] )
