Instructional Technology Resources

Audience Response Systems

Audience Response Systems (ARS) are used in classrooms of all sizes to engage participants by facilitating interactions among the students and the instructor. Instructors use audience response technologies to communicate with learners and collect feedback on questions. Learners respond to these questions using their own web-enabled devices, such as a phone, tablet, or laptop computer.


Columbia’s learning management system, CourseWorks, is at the center of many instructional technology activities. CourseWorks is supplemented and enhanced by other tools that support a range of instructional objectives, such as tools for online collaboration, presentations, lecture capture, audience response, media annotation, and electronic portfolios.
