Example of Audience Response System (ARS) question and the remote that is used in many of the bridge inspection courses

ARS enables participants to provide instant feedback to the instructor and fellow participantsinstructor and fellow participants

• Participants use the remote to select the answer

• Once the answer is selected by the participant, the signal from the remote is sent to a receiver that is plugged into the computer via USB port

• After the participants are done selecting the answers, the instructor closes polling and the answers of the participants appears with the correct answer appearing

• Group discussion follows based on answers provided by the participants
