Summary

The CodeGrader plugin was developed to ease the burden of Teaching Assistants (TAs) at University of Maryland. Every semester, TAs go through thousands of lines of student code manually, checking it for style, grading it, and reporting back to each student, explaining code style problems to help the students learn to code better.

In 2013, the idea and some code tailored for a couple of specific UMD course was introduced by Dr. Tak Yeon Lee, who shortly obtained his PhD in Human-Computer Interaction from UMD and moved on to Adobe Research. In 2020, another graduate student, Gregory Kramida, led the effort to implement the plugin so it can be used across any Java course in the UMD CS curriculum, introducing static code analysis and modules that can be configured for any UMD Java project using the internal Submit Server. William Kaiyang Siew and Matthew Walter Simmons, both undergraduate teaching assistants at the time, have since aided with the project, which is quickly becoming an indispensable productivity-booster for graders and a great way to issue more meaningful reports to students at a fraction of the time it took for manual grading.

The code is in active development. For submitting issues, feature requests, and contributing to the effort, please see the project repository at

Safety

Risk impact

CodeGrader requires a number of risky permissions that can potentially harm your browser and steal your data. Exercise caution when installing this extension. Review carefully before installing. We recommend that you only install CodeGrader if you trust the publisher.

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypass your security settings, and access your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Risk likelihood

CodeGrader may not be trust-worthy. Avoid installing if possible unless you really trust this publisher.

Risk likelihood measures the probability that a Chrome extension may turn malicious. This is determined by the publisher and the Chrome extension reputation on Chrome Web Store, the amount of time the Chrome extension has been around, and other signals about the Chrome extension. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Chrome extension, especially ones with higher risk impact and/or higher risk likelihood.
