Student assessment is a central component of instruction. Learning is affected by students' current knowledge and is facilitated when new knowledge and skills are consistent with and build upon current knowledge. The purpose of this project was to develop and validate a computer-delivered diagnostic formative assessment of geometric conceptions in the middle grades and to develop instructional resources to assist teachers in addressing flawed or underdeveloped conceptions identified by the a...

In this project, researchers developed NimbleTools, a universally designed test delivery platform that provides accessibility for students with disabilities. This project expanded the accessibility features that were in an initial beta version. For deaf and hearing-impaired students, the new features provided additional access to tests for through the use of signing. For blind students, the features included interactivity with electronic Braille displays. For students with language processin...

In this project, the researchers proposed to develop a set of computer-based algebra short tests, called testlets, that can provide teachers with information that they can use to guide instruction for individual students and groups of students who share similar problems with algebraic concepts. The researchers proposed that this tool would make classroom assessment a more instructionally useful component of teaching and learning. During the early 2000s, the tests used for mathematics achieve...
