Abstract

A computer assisted instructional information delivery system having at least two stations. One station for an instructor and one or more stations for students. An interactive monitor is positioned in each station. Each interactive monitor displays instructional information in visual form as inputted by a stylus or light pen on the interactive monitor. A network communication system operated by a central processing unit and corresponding software, communicates the instructional information from the stylus as inputted on one of the interactive monitors and selectively displays the instructional information simultaneously and concurrently onto any or all of the interactive monitors of the stations.
