Abstract: A distance education method to be implemented by a server device, and includes transmitting education course material to a client electronic device, which prompts for user input of a response to an interactive inquiry of the education course material and transmits the response to a server device, providing a solution to the interactive inquiry to the client electronic device, which prompts for user input of a correction to the response and transmits the correction to the server device, and generating an evaluation result, which is associated with a user learning outcome of the education course material, based on the correction and the solution.

Abstract: A sound repeater unit is to be used with an audio input equipment, such as a cassette or video tape recorder, and an audio output equipment, such as a television set or a loudspeaker. The audio input equipment has a control unit which is actuated so as to operate the audio input equipment in a paused state. The sound repeater unit includes a pause control circuit receiving an activating signal from the control unit and a programmable signal repeating circuit controlled by the pause control circuit so as to record continuously an audio frequency output of the audio input equipment while overwriting a previously recorded audio frequency output of the latter. The pause control circuit further controls the signal repeating circuit so as to output repeatedly a portion of the audio frequency output, which portion was recorded within a predetermined time period immediately before the audio input equipment was paused.
