We are developing an easy-to-use problem-solving assessment rubric to assess students' problem-solving skills based on their written problem solutions. The rubric has been tested for validity, reliability, and utility and that work is described in the doctoral dissertation of Jennifer Docktor (click here). The rubric has five categories:
Useful Description: representing information from the problem statement symbolically, visually, and/or in writing
Physics Approach: selecting relevant physics concepts and principles to apply to the problem
Specific Application of Physics: applying physics concepts and principles to the specific conditions in the problem
Mathematical Procedures: applying math rules and procedures in the context of physics
Logical Progression: the overall solution process is clear, focused toward a goal, and logically connected (consistent)
The rubric can be used either for research purposes or for general assessment purposes. For research purposes, a high inter-rater reliability is important. We have developed training materials to help novices learn to use the rubric for either purpose.

These materials help people learn how to apply the problem-solving rubric to score students' written problem solutions.
This is a more rigorous training process to achieve a high inter-rater reliability. Some repetition of the training process may be necessary. Sample student solutions used in the training and instructions are included.
