The 'Choice' tool allows tutors to ask a question and set up radio buttons which students can click to make a selection from a number of possible responses.
Tutors can set this up so students can choose one or more option and can upload their selection.
Top tip: Choices can be useful as a quick poll to stimulate thinking about a topic; to allow the class to vote on a direction for the course, or to gauge progress. For some practical ideas for using the Choice tool and other tools for feedback and formative assessment, visit the Teaching Toolshed pages.
