Psychometric models of student conceptions in science: Reconciling qualitative studies and distractor-driven assessment instruments
1998
Journal of Research in Science Teaching
We stand poised to marry the fruits of qualitative research on children's conceptions with the machinery of psychometrics. This merger allows us to build upon studies of limited groups of subjects to generalize to the larger population of learners. This is accomplished by reformulating multiple choice tests to reflect gains in understanding cognitive development. This study uses psychometric modeling to rank the appeal of a variety of children's astronomical ideas on a single uniform scale.
