What is Isomorphs

The purpose of this chapter is to describe and illustrate a template-based method for automatically generating test items. This method can be used to produce a large numbers of high-quality items both quickly and efficiency. To highlight the practicality and feasibility of automatic item generation, we demonstrate the application of this method in the content area of junior high school science. We also describe the results from a study designed to evaluate the quality of the generated science items. Our chapter is divided into four sections. In section one, we describe the methodology. In the section two, we illustrate the method using items generated for a junior high school physics curriculum. In section three, we present the results from a study designed to evaluate the quality of the generated science items. In section four, we conclude the chapter and identify one important area for future research.
