The second-generation interactive classroom television system (ICTS), which permits partially sighted students and their teachers to be in continuous two-way visual communication, was installed in Killian Elementary School, Rowland Heights, California, in November 1975. The capabilities of the first system (see R-1537-HEW), which is still in use at Madison Elementary School, Santa Monica, California, have been enlarged from four to eight stations and several major improvements have been made. This report describes the various parts of the new ICTS and how they interact with one another through the improved control system. The illustrated discussion demonstrates the power and versatility of the ICTS in presenting video and audio information to individual students or groups of students. Also described is the design and electronic implementation of the system.
