Educational device for programmed instruction
Abstract
Abstract TO REINFORCE THE LEANING PROCESS, PARTICULARLY IN RESPECT TO A FOREIGN LANGUAGE, A STUDENT LISTENS TO THE PLAYBACK OF INSTRUCTIONAL MATERIAL RECORDED ON TAPE AND SUBSEQUENTLY RECORDS HIS RESPONSE THERETO ON APPROPRIATE AREAS OF THE TAPE. IF THE INSTRUCTIONAL MATERIAL IS STORED ON AND PLAYED BACK FROM ONE TRACK OF A MULTIPLE-TRACED TAPE FED IN ONE DIRECTION THROUGH A BIDIRECTIONAL TAPE RECORDER, AND IF THE STUDENT''S RESPONSE IS RECORDED ON ANOTHER OF THE TRACKS OF THE TAPE IN THE OPPOSITE DIRECTION, REVERSAL OF THE DIRECTION OF MOVEMENT OF THE TAPE AFTER EACH OPERATION REPRESENTS CYCLICAL MOTION WHICH MAY BE REPEATED AS OFTEN AS DESIRED. THE REVERSAL OF THE TAPE DIRECTION IS AUTOMATIC AND CONTROLLED BY CUE MARKS RECORDED ADJACENT TO THE ENTRIES. THE LENGTH OF EACH CYCLE, AND THE NUMBER OF REPETITIVE CYCLES CAN BE REGULATED MANUALLY AS WELL AS AUTOMATICALLY.
