Abstract: With the advent of laptop computers and network technology, many classrooms are now being
equipped with Internet connections, either through wired connections or wireless infrastructure. Internet
access provides students an additional source from which to obtain course-related information. However,
constant access to the Internet can be a distraction. This distraction could potentially cause impaired
learning performance. Instructors need a mechanism to control how students access the Internet; and
researchers need a mechanism to monitor students' computer activities and engagement. To fulfill these
two needs, we propose a simple Classroom Network Access Control (CNAC) system. Our system
consists of two major parts: the Ethernet bridge as a core and the web-based control panel as the user
interface. The CNAC system is designed to be easily deployed and the simple and intuitive web-based
control panel provides a user-friendly configuration interface for instructors. Through this powerful, yet
flexible interface, instructors can easily set classroom Internet access rules.
