Multiple student teaching apparatus and method

Claim 2

Audiovisual multiple student teaching apparatus including: a. first means for selectively presenting a programmed visual display to each of the students; b. second means, including a pair of headphones, for presenting a programmed audible signal to each student; c. third means for immediately superimposing a secondary audible signal generated by a particular student onto the programmed audible signal presented to that student, through said headphones; d. control means for synchronizing the visual display presented to each student with the programmed audible signal presented to each student; e. means for selectively presenting any one of said secondary audible signals at a remote station; and f. means for superimposing an auxiliary audible signal onto said programmed audible signal presented to each student.

Claim 3

The apparatus of claim 1 wherein said second means includes a tape deck having two output channels, a recording medium having two channels carried on said tape deck, one of said channels having the master programmed information thereon, said tape deck producing one of its outputs in accordance with the programmed information on said one channel of said medium, and amplification means having its input connected to said one of the outputs of said tape deck, said headphones being connected to the output of said amplification means to convert the output of said amplification means into an audible signal for the signal for the student wearing said headphones, said amplification means including a volume control for regulating the amplitude of the output of said amplification means.

Claim 4

The apparatus of claim 1 wherein said third means includes, a conversion device for converting an audible signal generated by the student wearing said headphones into a secondary input operatively connected to said amplification means, said amplification means being constructed and arranged to superimpose said secondary input onto one of the outputs of said tape deck; and secondary volume control means operatively connected to said conversion device for selectively adjusting the amplitude of said secondary signal.

Claim 5

An audiovisual multiple student teaching device comprising: a projection device having an advance mechanism for projecting programmed visual images to the students, a two-channel tape deck; a two-channel tape operably carried by said tape deck and including a first channel having a programmed master signal thereoN and a second channel having a synchronizing signal thereon, said tape deck constructed and arranged to produce a first output in accordance with said programmed master signal and a second output in accordance with said synchronizing signal; an audio amplifier having its input selectively connected to said first output of said tape deck; a sync amplifier having its input selectively connected to said second output of said tape deck, and its output operatively connected to said advance mechanism of said projection device to cause said device to display the next successive visual image to the students in accordance with said synchronizing signal; a plurality of student amplifiers having their inputs connected in parallel to the output of said audio amplifier, each of said student amplifiers operatively connected to a pair of headphones for a particular student; a plurality of student input conversion means, each of said conversion means operatively associated with a particular student amplifier and generating a secondary input signal to said particular student amplifier in response to an audible signal generated by the students wearing said pair of headphones connected to said particular student amplifier, said student amplifier superimposing said secondary input signal onto said output from said audio amplifier and supplying same as an amplified output to said headphone set; a monitoring amplifier; switching means selectively connecting said amplified output of each of said student amplifiers to said monitoring amplifier; a speaker operatively connected to the output of said monitoring amplifier to convert said amplified output from the selected one of said student amplifiers into an audible output; a microphone; a selector switch selectively connecting said microphone to the input of said audio amplifier to superimpose a signal from said microphone onto the output of said audio amplifiers; and, power supply means for supplying amplification power to said audio, sync, student, and monitoring amplifiers.
