In code comprehension tasks, students may be asked to explain critical steps of the code. |
|
The ability to automatically assess these self-explanations offers a unique opportunity to understand the current state of student knowledge, |
|
recognize possible misconceptions, and provide feedback. Annotated datasets are needed to train Artificial Intelligence/Machine Learning approaches for the |
|
automated assessment of student explanations. To answer this need, we present a novel corpus called SelfCode which consists of |
|
1,770 sentence pairs of student and expert self-explanations of JAVA code examples along with semantic similarity judgments provided by experts. |

## Data Set Example |
|
| Line of Code | Crowd Sourced Explanation | ExpertExplanation | Annotation Score | |
|
| --- | --- | ---| --- | |
|
| int [] arr = { 1, 2, 3}; | Declares the array we want to use for our assignment | We initialize the array of type int to hold the specified numbers. | 4 | |
|
| int num = 15; | variable decleration: declares the number we are trying to divide | We could initialize it to any positive integer greater than 1. | 1 | |
|
| divisor += 1; | if the loop condition is true, then we increment the divisor by 1 | When the divisor is not a factor of the number, we increment the variable divisor by 1. | 3 | |
|
| int seconds = scan.nextInt(); | Get the number entered by the user. | We read the seconds by calling the nextInt() method because this input is an integer. | 2 | |
|
| System.out.println("Enter an integer: "); | Ask the user to enter an integer. | We prompt the user to enter an integer.| 5 | |
