A Classroom Response System (CRS) is technology that helps to promote class participation. CRS systems allows students to answer questions posed by the lecturer in class with the summary results displayed almost immediately on screen. NUS uses two CRS:
Clickers, a physical keypad system;
PeerQuestions, an SMS and web-based system, and
Archipelago, a web application.
NUS uses Turning Point classroom clickers.
This system consists of a radio frequency receiver connected to a computer via USB, a set of response units (one is pictured on the top right) and the TurningPoint software which enables the interactive responses.
PeerQuestions is a virtual classroom response system. Lecturers can ask questions in class, and students can answer via SMS or the web.
Archipelago is a lightweight web application created to inject interactivity into classes.
Students, in team or solo, can response to a wide variety of questions posted by the instructor. Real time collation tools helps the instructor to make sense of the student responses on the fly.
