Abstract
Abstract An electronic learning device (10) for teaching how to tell time is provided. A student provides input to the device, in a preferred embodiment, by a plurality of keys (14) which select the learning activity and its difficulty level. In certain activities, the device (10) request (visually and/or auditorily) the student to engage in a randomly selected time-identification problem. The student's response is compared with the correct response, and the information concerning the appropriateness of the response is provided to the student. In the case of erroneous response, the correct response can be presented to the student both orally and visually. A speech synthesizer (38) (and/or analog and/or digital display) serves to generate a request to the student concerning time identification problems, and comments on the appropriateness of the student's response. In the preferred embodiment, the device is provided with a plurality of operational modes ranging from merely generating an audio signal identifying the correct time to engaging in interactive activities and games related to time identification problems.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
96 words
An electronic learning device comprising: student input means for generating a code representative of time; interrogation (visual and/or auditory) means responsive to said code generated by said student input means to request said student to engage in a selected time-identification problem; comparison means responsive to reading a specific code generated by said input means in response to said request to determine if said specific code corresponds to a correct student response to said time-identification problem; and a display means to effect said request and comment on the appropriateness of response by said student to time-identificatin problems.
Claim 2
Dependent Claim
96 words
An electronic learning device comprising: student input means for generating a code representative of time; interrogation (visual and/or auditory) means responsive to said code generated by said student input means to request said student to engage in a selected time-identification problem; comparison means responsive to reading a specific code generated by said input means in response to said request to determine if said specific code corresponds to a correct student response to said time-identification problem; and a display means to effect said request and comment on the appropriateness of response by said student to time-identificatin problems.
Claim 3
Dependent Claim
16 words
The device of claim 1 wherein said means to effect said request comprises speech synthesis means.
Claim 4
Dependent Claim
27 words
The device of claim 2 including motor means for rotating hands of an analog clock to a selected location indicating an appropriate response to a time-identification problem.
Claim 5
Dependent Claim
15 words
The device of claim 1 wherein said means to effect said request comprises display means.
Claim 6
Dependent Claim
21 words
The device of claim 4 including means for scoring the responses of said student to requests generated by said interrogation means.
Claim 7
Dependent Claim
20 words
The device of claim 5 including a plurality of scoring means for recording scores accumulated by more than one player.
Claim 8
Dependent Claim
28 words
The device of claim 1 including motor means for rotating said hands of an analog clock to a selected location indicating an appropriate response to a time-identification problem.
Claim 9
Dependent Claim
113 words
An electronic learning device comprising: student input means having first input means for generating an input code representative of a selected activity and further input means which generates a code representative of time; interrogation means responsive to said code generated by said student input means to request said student to engage in a selected time-identification problem; comparison means responsive to reading a specific code generated by said further input means in response to said request to determine if said specific code corresponds to a correct student response to said time-identification problem; and a speech synthesis means to effect said request and comment on the appropriateness of responses by said student to time-identification problems.
Claim 10
Dependent Claim
113 words
An electronic learning device comprising: student input means having first input means for generating an input code representative of a selected activity and further input means which generates a code representative of time; interrogation means responsive to said code generated by said student input means to request said student to engage in a selected time-identification problem; comparison means responsive to reading a specific code generated by said further input means in response to said request to determine if said specific code corresponds to a correct student response to said time-identification problem; and a speech synthesis means to effect said request and comment on the appropriateness of responses by said student to time-identification problems.
Claim 11
Dependent Claim
133 words
An electronic learning device comprising: student input means having first input means for generating an input code representative of a selected activity and further input means comprising an analog clock having student operable hands mechanically connected to encoders which generate a code representative of the time identified by the position of said hands; interrogation means responsive to said code generated by said student input means to request said student to engage in a selected time-identification problem; comparison means responsive to reading a specific code generated by said further input means in response to said request to determine if said specific code corresponds to a correct student response to said time-identification problem; and a speech synthesis means to effect said request and comment on the appropriateness of responses by said student to time-identification problems.
Claim 12
Dependent Claim
133 words
An electronic learning device comprising: student input means having first input means for generating an input code representative of a selected activity and further input means comprising an analog clock having student operable hands mechanically connected to encoders which generate a code representative of the time identified by the position of said hands; interrogation means responsive to said code generated by said student input means to request said student to engage in a selected time-identification problem; comparison means responsive to reading a specific code generated by said further input means in response to said request to determine if said specific code corresponds to a correct student response to said time-identification problem; and a speech synthesis means to effect said request and comment on the appropriateness of responses by said student to time-identification problems.
Claim 13
Dependent Claim
24 words
The device of claim 9 wherein said first input means includes means for generating an input code representative of a selected activity difficulty level.
Claim 14
Dependent Claim
30 words
The device of claim 9 wherein said further input means includes student operable keys in response to which a code is generated representative of time identified on a digital clock.
Claim 15
Dependent Claim
27 words
The device of claim 9 including motor means for rotating said hands of said clock to a selected location indicating an appropriate response to a time-identification problem.
