Methods, systems, and media for identifying and scoring assignment answers

1. A system for identifying and scoring assignment answers, comprising:

a memory; and

a hardware processor coupled to the memory and configured to:

receive a definition of an assignment having a plurality of questions;

identify correct answers to the questions;

receive student answers to the questions for a student;

create a converted answer for one of the student answers based on at least one of: spell-checking the one of the student answers; converting the one of the student answers based on a mathematical rule; converting the one of the student answers based on a mathematical property; converting a letter of the one of the student answers to a number; and normalizing the one of the student answers to use a particular notation;

before determining whether the student answer is correct, present the converted answer to the student for verification;

determine whether the student answer is correct by comparing the converted answer to a corresponding one of the correct answers; and

determine a grade on the assignment for the student based on the comparing the converted answer to the corresponding one of the correct answers.

2. The system of claim 1 , wherein the hardware processor is also configured to correct at least one of the student answers.

3. The system of claim 1 , wherein the hardware processor is also configured to perform character recognition on an image to produce the student answers.

4. The system of claim 1 , wherein the hardware processor is also configured to identify student answers based on a template of the assignment.

5. The system of claim 1 , wherein the creating the converted answer is based at least on converting the one of the student answers based on a mathematical property, and wherein the mathematical property is one of a commutative property and a distributive property.

6. The system of claim 1 , wherein the creating the converted answer is also based on a type of answer expected as the one of the student answers.

7. A method for identifying and scoring assignment answers, comprising:

receiving a definition of an assignment having a plurality of questions;

identifying correct answers to the questions;

receiving student answers to the questions for a student;

creating a converted answer for one of the student answers based on at least one of: spell-checking the one of the student answers; converting the one of the student answers based on a mathematical rule; converting the one of the student answers based on a mathematical property; converting a letter of the one of the student answers to a number; and normalizing the one of the student answers to use a particular notation, using a hardware processor;

before determining whether the student answer is correct, presenting the converted answer to the student for verification;

determining whether the student answer is correct by comparing the converted answer to a corresponding one of the correct answers using the hardware processor; and

determining a grade on the assignment for the student based on the comparing the converted answer to the corresponding one of the correct answers.

8. The method of claim 7 , further comprising correcting at least one of the student answers.

9. The method of claim 7 , further comprising performing character recognition on an image to produce the student answers.

10. The method of claim 7 , further comprising identifying student answers based on a template of the assignment.

11. The method of claim 7 ,

wherein the creating the converted answer is based at least on converting the one of the student answers based on a mathematical property, and wherein the mathematical property is one of a commutative property and a distributive property.

12. The method of claim 7 , wherein the creating the converted answer is also based on a type of answer expected as the one of the student answers.

13. A non-transitory computer-readable medium containing computer-executable instructions that, when executed by a processor, cause the processor to perform a method for identifying and scoring assignment answers, the method comprising:

receiving a definition of an assignment having a plurality of questions;

identifying correct answers to the questions;

receiving student answers to the questions for a student;

creating a converted answer for one of the student answers based on at least one of: spell-checking the one of the student answers; converting the one of the student answers based on a mathematical rule; converting the one of the student answers based on a mathematical property; converting a letter of the one of the student answers to a number; and normalizing the one of the student answers to use a particular notation;

before determining whether the student answer is correct, presenting the converted answer to the student for verification;

determining whether the student answer is correct by comparing the converted answer to a corresponding one of the correct answers; and

determining a grade on the assignment for the student based on the comparing the converted answer to the corresponding one of the correct answers.

14. The non-transitory computer readable medium of claim 13 , wherein the method further comprises correcting at least one of the student answers.

15. The non-transitory computer readable medium of claim 13 , wherein the method further comprises performing character recognition on an image to produce the student answers.

16. The non-transitory computer readable medium of claim 13 , wherein the method further comprises identifying student answers based on a template of the assignment.

17. The non-transitory computer readable medium of claim 13 , wherein the creating the converted answer is based at least on converting the one of the student answers based on a mathematical property, and wherein the mathematical property is one of a commutative property and a distributive property.

18. The non-transitory computer-readable medium of claim 13 , wherein the creating the converted answer is also based on a type of answer expected as the one of the student answers.
