Abstract
Abstract A movable record, such as a magnetic tape stores instructional items in paragraph form; associated with each instructional item is a code, recorded on the tape, indicative of a correct answer. A student-operated keyboard is provided which, upon depression of a key indicative of the correct answer, as instructed by the instructional item recorded on the tape, will provide a signal which is compared with a signal derived from the code recorded on the tape and, upon coincidence, causes the tape to proceed to the next instructional item. Upon non-coincidence, an''''error response'''' is indicated; the next, or a subsidiary instructional item will be displayed to the student when a predetermined number of incorrect answers has been counted. The ends of items and switch-over of mode of the receiver (from sound for the student to decoding) is controlled by a special frequency recorded on the tape.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
263 words
Teaching machine comprising a movable recording means to store instructional items thereon for presentation to a student, said movable recording means having a magnetic track to record, in form of magnetic digital pulses in a predetermined sequence, a code indicative of a correct answer to represent binary numbers in the predetermined sequence; transducer means associated with said recording means and having an output device providing a human recognizable output from said storage means, and further providing an output electrical signal representative of the code of the correct answer; a student operated keyboard, recording studenT-generated answers entered thereon; indicator circuits indicating correct and incorrect answers entered in said keyboard; a first storage circuit storing the code indicative of the correct answer provided by said recording means; means responsive to operation of a plurality of keys of said keyboard in the sequence of their operation and providing coded signals arranged in a binary digital code, in which a unique number is assigned to each key, said code being similar to said recorded code, the operation of a selected number of predetermined keys in a specific sequence providing a response code comprising unique binary numbers in said sequence; and comparator means comparing the code stored in said first storage means and the answer code provided by said keyboard, the output of said comparator means being connected to said indicator circuit to indicate match and mismatch of said codes and thus correct and incorrect answers detected by coincidence, or non-coincidence of the keyboard generated answer code and the recorded code, in said sequences, in said comparator means.
Claim 2
Dependent Claim
263 words
Teaching machine comprising a movable recording means to store instructional items thereon for presentation to a student, said movable recording means having a magnetic track to record, in form of magnetic digital pulses in a predetermined sequence, a code indicative of a correct answer to represent binary numbers in the predetermined sequence; transducer means associated with said recording means and having an output device providing a human recognizable output from said storage means, and further providing an output electrical signal representative of the code of the correct answer; a student operated keyboard, recording studenT-generated answers entered thereon; indicator circuits indicating correct and incorrect answers entered in said keyboard; a first storage circuit storing the code indicative of the correct answer provided by said recording means; means responsive to operation of a plurality of keys of said keyboard in the sequence of their operation and providing coded signals arranged in a binary digital code, in which a unique number is assigned to each key, said code being similar to said recorded code, the operation of a selected number of predetermined keys in a specific sequence providing a response code comprising unique binary numbers in said sequence; and comparator means comparing the code stored in said first storage means and the answer code provided by said keyboard, the output of said comparator means being connected to said indicator circuit to indicate match and mismatch of said codes and thus correct and incorrect answers detected by coincidence, or non-coincidence of the keyboard generated answer code and the recorded code, in said sequences, in said comparator means.
Claim 3
Dependent Claim
32 words
Teaching machine according to claim 1, including a second storage circuit storing the answer code derived from said keyboard, the outputs of both said storage circuits being applied to said comparator means.
Claim 4
Dependent Claim
60 words
Teaching machine according to claim 2, wherein said keyboard contains alphanumeric representations and an additional special key (17), said special key controlling advance of said recording means, and clearance of said storage circuits (10, 16); said machine including a counter means counting correct and incorrect answers, said special key further re-setting at least one of said counter means to zero.
Claim 5
Dependent Claim
22 words
Teaching machine according to claim 3, wherein each key, except the special key, is associated with a plurality of separate alpha-numerical representations.
Claim 6
Dependent Claim
50 words
Teaching machine according to claim 1, wherein said instruction items are stored in the form of recorded sound signals on the sound track of the movable recording means, and covering a first frequency band; and control signals having a frequency outside said frequency band are recorded on said recording means.
Claim 7
Dependent Claim
40 words
Teaching machine according to claim 1, wherein said instruction items are stored in the form of recorded sound signals on said recording means on one track thereof; and control signals are recorded on said recording means on another parallel track.
Claim 8
Dependent Claim
32 words
Teaching machine according to claim 1, including human readable read-out means connected to said keyboard and having the coded signals applied thereto to provide a human readable output of the student''s answer.
Claim 9
Dependent Claim
47 words
Teaching machine according to claim 7, including a further input connected to said read-out means to apply the code delivered from said record means thereto to provide, additionally, a human readable output of the correct answer to enable checking of the correct answer against the student''s answer.
Claim 10
Dependent Claim
62 words
Teaching machine according to claim 1, including a counter means (26) connected to count correct and mistaken replies, and connected to the output of said comparator means, said counter, upon counting a correct answer, or upon a predetermined number of incorrect answers having been counted, controlling further movement of said movable recording means to present a further instruction item to the student.
Claim 11
Dependent Claim
53 words
Teaching machine according to claim 9, wherein said recording means has primary instruction items and secondary instruction items recorded thereon; and said counter means, upon counting to a predetermined count of mistaken answers, control said transducer means and said movable recording means to provide a human recognizable output from a secondary instruction item.
Claim 12
Dependent Claim
78 words
Teaching machine according to claim 1, wherein said transducer means includes a signal-responsive means; said recording means has a signal having a predetermined characteristic recorded thereon indicative that the end of An instructional item has been reached, said signal-responsive means responding to said predetermined characteristic; and a switch-over means is provided responsive to said signal-responsive means, connected to interrupt interconnection of said transducer means to the output device and connect said transducer means to said first storage means.
Claim 13
Dependent Claim
22 words
Teaching machine according to claim 11, wherein said switch-over means is further connected to stop continued movement of said movable recording means.
