Based on your search query, I recommend Gradescope as a suitable EdTech tool for managing homework.

Gradescope is a powerful tool that allows teachers to grade both individual student assignments and exams. It uses artificial intelligence to assist in grading written exams and homework, making the process more efficient.

One of the key features that could be particularly useful for you is the Dynamic Point Adjustment Rubric. This feature allows you to change grading criteria even while grading, ensuring flexibility and adaptability to different student responses.

Another feature that could be beneficial is the Integration with Learning Systems. If you're already using learning systems like Canvas or Brightspace, Gradescope can easily sync with these platforms, simplifying the process of adding class rosters and pushing grades.

Lastly, Gradescope provides Consistent Feedback across multiple submissions, ensuring uniform grading and fair assessment for all students.

Remember, Gradescope offers a free basic plan that includes dynamic rubrics, basic assignment types, statistics, and a student mobile app. So, you can try it out and see if it meets your needs before deciding on a paid plan.
