Abstract
An audio-visual educational aid which coordinates reading of textual material with an audio presentation of the material. An audio reproduction of the material is made on a recording medium together with audio player control signals. A student reader 'reads along' with the audio reproduction, and is provided with a control button which he is to depress upon reaching the end of a predefined portion of textual material, such as the end of a line. If the button is not depressed within a pre-determined time, circuitry within the educational aid stops the audio player and prevents it from resuming until a restart button is depressed, and a punitive time delay has lapsed. The length of the time delay is increased with each stoppage of the player. Various additional features are incorporated into the educational aid to provide reinforcement to the reader.
