Concentration Analysis: A Quantitative Assessment of Student States.
Bao, Lei; Redish, Edward F.
Multiple-choice tests such as the Force Concept Inventory (FCI) provide useful instruments to probe the distribution of student difficulties on a large scale. However, traditional analysis often relies solely on scores (number of students giving the correct answer). This ignores what can be significant and important information: the distribution of wrong answers given by the class. In this paper a new method is introduced called "concentration analysis" to measure how students' responses on multiple-choice questions are distributed. This information can be used to study if the students have common incorrect models or if the question is effective in detecting student models. When combined with information obtained from qualitative research, the method can be used to identify cleanly what FCI results are saying about student knowledge.
