ABSTRACT:
A learning apparatus in which a memory contains a first plurality of data units and a second plurality of data units each of which is related to a unit of the first program. Switches are provided for switching between the first and second pluralities of data units and for switching between the units within the selected plurality. Reading means are provided for reading a designated unit of data from the memory, based on a signal from the operation switch, thus making it possible to access and reproduce any desired program or articles related to the program. In another embodiment, a control memory holds the addresses of the data units, and the reading means obtains the address of the selected data unit from the control memory and reads the data at that address. The apparatus is uniquely suited for audio teaching material, such as languages, but may be used with any information which may be organized into logically related units.
