The ITV Schools broadcasts gave teachers access to a broad spectrum of teaching resources, such as documentary film with which to illustrate their regular lessons, or songs and stories for children to learn and discuss, and could be considered an early example of multimedia learning. Activities and booklets based on the programmes were available to teachers via the educational officers based at the local ITV companies, allowing students to develop a relationship with the regular broadcasts. Typically, schools were equipped for schools television with a couple of large television receivers, sometimes housed inside a wooden cabinet atop a wheeled trolley which could be moved between classrooms as required.
