Research Description:

My Ph.D. dissertation topic is problem solving assessment, and my thesis adviser is Dr. Ken Heller. I am revising a problem solving scoring rubric to evaluate written solutions to physics problems that was used in previous research at the University of Minnesota.

I completed initial testing of a draft rubric on student and instructor solutions in summer 2007 [see AAPT summer 2007 talk and poster], piloted the instrument with graduate students in fall 2007 - spring 2008 [see AAPT summer 2008 talk and poster], and plan to continue further studies of reliability and validity.


Problem Solving Rubric Categories:

Recent rubric versions evaluate physics problem solving across five dimensions:

  1. Useful Description: representing information from the problem statement symbolically, visually, and/or in writing

  2. Physics Approach: selecting relevant physics concepts and principles to apply to the problem

  3. Specific Application of Physics: applying physics concepts and principles to the specific conditions in the problem

  4. Mathematical Procedures: applying math rules and procedures in the context of physics

  5. Logical Progression: the overall solution process is clear, focused toward a goal, and logically connected (consistent)
