An Item Response Curves Analysis of the Force Concept Inventory

Force Concept Inventory

Every student begins physics with a well-established system of commonsense beliefs about how the physical world works derived from years of personal experience. Over the last decade, physics education research has established that these beliefs play a dominant role in introductory physics. Instruction that does not take them into account is almost totally ineffective, at least for the majority ...

Item response analysis of the inventory of depressive symptomatology

BACKGROUND: Both the clinician (IDS-C(30)) and self-report (IDS-SR(30)) versions of the 30-item Inventory of Depressive Symptomatology have acceptable psychiatric properties and have been used in various clinical studies. These two scales, however, have not been compared using item response theory (IRT) methods to determine whether the standard scoring methods are optimal. METHODS: Data were de...

Bayesian Estimation of Item Response Curves

We will consider dichotomous responses to a set of test items which are designed to measure the abilities of individuals. We assume that each item is characterized by an item response curve, a function of ability which is indexed by unknown parameters called item parameters. We consider a Bayesian method for estimating these parameters when the abilities of the individuals are assumed to have a...
