The GoogleDocs Form is an efficient way for teachers to collect small pieces of information because it automatically displays the information in a spreadsheet. Teachers can add formulas to those spreadsheets to create multiple-choice quizzes that grade themselves. Since a form can be linked or embedded into a website, wiki or blog, students do not need email accounts to take a quiz. The form works well on any portable computing device or full-blown computer which makes it perfect for use as an Exit Ticket at the end of a lesson. One simple 3-5 question Exit Ticket Quiz has at least three great uses.
