Grade-It is addressing one of the most challenging problems in STEM education: how to automate the assessment of quantitative constructed-response problems (QCRPs), commonly known as “word problems”. This includes two use cases, assessment (automated scoring for partial credit) and learning (providing timely, specific, detailed feedback to students so they can learn to solve word problems more effectively).

Grade-It is the first software system that is able to meaningfully assess QCRPs for partial credit, replacing the expert human grader with a sophisticated algorithm combining deep search of the solution space with analysis of algebraic equivalence to detect elements of the student’s work that correspond to steps in the grading rubric. More accurate grading for partial-credit problems at a higher efficiency and lower cost, and instant, specific feedback to support students’ development of the higher-order problem-solving skills that are essential in STEM.

Our platform is intuitive and easy to use. It can be used for upper elementary to university STEM classes.

Grade-It will soon be commercially available.
