Overview of MathNet57789
MathNet57789 is a dataset of K-12 students’ handwritten images given as a response to answering open-ended math questions. The dataset is collected from the ASSISTments online learning platform over the 2019-2023 school years, from grade 2 through high school students. The dataset consists of images that are redacted of Personally Identifiable Information(PII) by cropping the background and masking off any remaining PII with black rectangular boxes.
Data Source
This dataset includes two files: 1. MathNet57789 Problem Logs and 2. Problem Bodies.
MathNet57789 Problem Logs points to students' answers given as a response to math problems and this dataset maps to the Problem Bodies on the problem_id. Problem Bodies includes the math problems that students are answering.
The images in the MathNet57789 dataset were created during a joint project between Dr. Heffernan’s lab at WPI and ASSISTments, where students upload their handwritten math work and receive feedback from teachers. Dr. Heffernan’s lab is releasing this data set as part of their responsibility to release de-identified data under the tenets of Open Science as part of receiving NSF grants.
Sharing Agreement
This dataset is licensed under CC-BY-NC-4.0. We require that this dataset is used for research and educational purposes following this Responsible Use Guidelines.
We have taken measures to de-identify these images and are confident that they are free of PII. In the event that you encounter any PII, like their names. We ask you to report the file name to us and delete the image. Please report the details including the file name of such images by emailing etrials@assistments.org.
Describing the Dataset
The dataset was reviewed by a group of students at WPI who manually looked into the individual images in this dataset and cropped these images to remove any backgrounds, then masked off the remaining PIIs with black rectangular boxes. Blank or empty images were removed from the dataset.
The Mathnet57789 dataset contains 57,789 handwritten images from 21,212 different students answering 192 different math problems in the ASSISTments learning platform. Below is the summary statistics of the dataset:
