Abstract
Abstract A calculator-type educational device for teaching arithmetic which provides features to motivate a student to greater learning progress including means for reporting the student's arithmetic proficiency by means of post-test statistics that are displayed after completion of a problem set. A dual mode of operation is provided, namely, a first mode in which a selected number of problems is presented for a student to solve at his own pace without any specified time limit and a second mode in which the student is presented problems in a specified period of time, the number of problems being determined solely by how rapidly the student can offer a proposed solution to each such problem. An additional unique feature of the present invention is the availability of numerical limits and factor multiples to which the problem parameters are related. The disclosed embodiment incorporates a microprocessor-based programmed computer in a desk-type calculator configuration.

In an electric arithmetic teaching apparatus of the type having: a keyboard having numerical value keys for entering numerical parameters of arithmetic problems to be presented to a student and for entering proposed solutions to problems presented to the student; a display for indicating the numerical parameters of problems presented to the student and the proposed solution entered by the student; and a programmed computer for generating arithmetic problems for presentation, for processing proposed solutions, and for indicating by means of the display whether or not such proposed solutions are correct; the improvement comprising: means on said keyboard, including a key of no numerical value, for selecting a first mode of operation in which a selected number of problems are presented to the student for solution without a time limit; means on said keyboard, including a key of no numerical value, for selecting a second mode of operation in which problems are presented to the student for solution within a selected time limit; and means within said programmed computer responsive to said first mode selecting means and to said second mode selecting means for controlling problem presentation and processing in accordance with the selected mode of operation.
Claim 3
Dependent Claim
88 words
The improvement recited in claim 1, wherein said first mode selecting means comprises: a key on said keyboard which, when depressed in sequence with selected numerical value keys on said keyboard, establishes said number of problems for said first mode in conjunction with said computer responsive means; and wherein said second mode selecting means comprises: a key on said keyboard which, when depressed in sequence with selected numerical value keys on said keyboard, establishes said time limit for said second mode in conjunction with said computer responsive means.
Claim 4
Dependent Claim
75 words
The improvement recited in claim 2 further comprising: means on said keyboard for selecting separate ranges for said numerical parameters to be presented to a student, each such range being defined by an upper limit and a lower limit, each such limit being selectable by means of a key on said keyboard which, when depressed in sequence with selected numerical value keys on said keyboard, establishes said limit in conjunction with said computer responsive means.
Claim 5
Dependent Claim
64 words
The improvement recited in claim 3 further comprising: means on said keyboard for selecting numerical factors of which the respective numerical parameters of problems presented to a student are multiples; said selecting numerical factors means comprising a key on said keyboard which, when depressed in sequence with selected numerical value keys on said keyboard, establishes said factors in conjunction with said computer responsive means.
Claim 6
Dependent Claim
110 words
The improvement recited in claim 4 further comprising: means in said programmed computer and in said display for determining and displaying statistics related to a student's problem solution performance and comprising: means in said programmed computer and in said display for determining and displaying percentage of problems answered correctly; means in said programmed computer and in said display for determining and displaying average response time to answer a problem; means in said programmed computer and in said display for determining and displaying total number of problems presented; and means in said programmed computer and in said display for determining and displaying total elapsed time for doing a set of problems.
Claim 7
Dependent Claim
37 words
