Abstract: A portable, self-powered teaching machine which provides the student with programmed audio instructional material in conjunction with a monaural or stereo cassette tape recorder/player, such as is available in the classroom. An audio frequency detection and switching circuit in the teaching device responds to control signals recorded within the programmed lesson, resulting in deactivation of the cassette recorder/player at certain intervals. At certain intervals, the student is instructed to insert a coded panel displaying interrogative visual information into a frame on the face of the teaching machine. Upon insertion, coded indicia on the panel establish a singular, correct response circuit in conjunction with sensing means adjacent to the panel. Response switches are contained on the teaching device which, if manipulated correctly by the student in accordance with a correct manner, will cause the cassette recorder/player to again be activated. A student response may be either numerical or alphabetical in nature, in accordance with what is required, and may consist of the identification, in proper order, of the exact letters of a word, portion of a word, a numerical value, or portion of a numerical value without reference to multiple choice identification. Other than prescribing a specific programmed lesson cassette for the student, according to his or her educational needs, little or no teacher involvement is necessary.
