Subject: Quantify the difficulty of physics problems

Assessment methods are broadly recognised as integral to effective instruction. Student performance on tests are a common way for instructors to gauge their instructional effectiveness. However, Lack of alignments of problem difficulty between instructors, institutions, and courses is the major obstacle to make use of authentic student performance data gathered by most classes and used by instructors. In this presentation, I will describe the development and validation of a simple difficulty assessment for assessing open response physics problems’ difficulty. It quantify the difficulty of physics problems. It can be used to compare test or homework problems , or to craft instruction material.
