A radio-controlled teaching device comprising a teacher transmitter unit and a plurality of student receiver units for maintaining student alertness during oral reading of written textual material, for the oral administration of multiple-choice or true or false test material, and for the preparation and presentation of recorded programmed instructional material. The teacher transmitter unit contains a tone generator and radio transmitter which transmits discrete tone signals, either under manual control of the teacher or automatically under the control of a plural channel instructional tape recording. Each student receiver unit contains timers, a logic circuit, and a radio receiver which receives the above tone signals (which are transparent to the students) and provides a short time period during which the student is expected to respond by briefly closing a response switch. The short time periods correspond to portions of a text being orally read, such as the end of a paragraph, proper nouns, verbs, etc., which the teacher wishes to emphasize, or to the correct answer of a multiple-choice or true or false question which is also being orally read, or to a designated point within a recorded programmed lesson which is being played back by a tape player. If the student responds during the above time period, he receives a “right”score which is displayed on a digital readout. If the student responds at any time other than the above time period, he receives a “wrong”score which is also displayed. Whether or not the teacher wishes to record the scores, the students are aware they are individually challenged by the teaching device.
