Abstract

A system for using a computer to record and grade answers to problems that have numerical answers, where problem statements have alphanumeric parameters that are replaced by digits taken from an identification code. Students are asked to solve the same problem statements with either the same or distinct identification codes; in the latter case, each must perform a different calculation to get the correct answer. Each student is provided with a transportable memory means such as a floppy diskette which is specially programmed to prompt for answers and record them in a computer-readable form. Grading then consists of using said memory means as input to a computer program that reads the currently recorded answers, determines which are correct, informs the student of the results, and records the results on a system file which provides current information for the instructor but is inaccessible to the students. Incorrect answers can be reworked and resubmitted as needed during a time period specified by the instructor.

Claims

1. A system for grading answers to a set of problem statements submitted to a group of students, each problem statement including selectable alphanumeric parameters, each parameter representing a number to be selected from one of a plurality of unique identification codes, each code comprising a plurality of numerals in a predetermined order, including;

a. a transportable preprogrammed student memory means which requests and stores a unique identification code as well as information from the student comprising answers to problem statements;

b. grading means, including receptacle means to read student memory means in order to receive said unique identification code, determine the correct answers in accordance with said unique identification code and use the correct answers to grade the submitted answers, store the results on one or more electronic memory means, and report results;

c. grading apparatus, wherein said receptacle means receives said student memory device, reads said identification code and answer information from said student memory device, determines the correct answers in accordance with said unique identification code, and uses said correct answers to grade the submitted answers.

2. The invention of claim 1 wherein said identification code assigned to each student is different than the identification code assigned to any other student, hence results in answers unique to that student.

3. The invention of claim 1 wherein said problems submitted to said students are selected from a larger set of problem statements stored in a manner which allows problem statements to be displayed either in terms of selectable parameters or with specific selected values.

4. The invention of claim 1 including display means to receive said student memory means and to display said requests for information from said student.

5. The invention of claim 4 wherein said display means includes information input means to receive responses from said student to said requests for information and record said responses on said student memory means.

6. The invention of claim 4 wherein messages to said student can be recorded on said student memory device and displayed on said display means.

7. The invention of claim 1 wherein said student memory means includes means to request messages from said student, display said requests for messages from said student and record said messages on said student memory means.

8. The invention of claim 1 wherein said grading apparatus includes system memory means to store answers to said problem statements for sets of identification codes and to record results of comparison of answers stored in said system memory means with said student memory device in said system memory means and on said student memory device.

9. The invention of claim 8 wherein said grading apparatus includes receptacle means to receive said student memory device and transmit information stored on said student memory device to said grading apparatus system memory means wherein said receptacle means and said grading apparatus system memory means are separated by barrier means and said system memory means is inaccessible to said student.

10. The invention of claim 8 wherein said grading apparatus includes calendar means, said problem statements include time periods during which answers are to be submitted and said grading apparatus includes means to verify that response to problem statements are submitted within the permissible time period.

11. The invention of claim 8 wherein said grading apparatus is adapted to receive answers to problem statements according to identification codes and hold same in said system memory means for comparison with answers submitted from said student memory device.

12. The invention of claim 1 wherein said grading apparatus determines answers to said problem statements upon receipt of a unique identification code.
