Much debate surrounds the issue of whether allowing candidates to listen to recordings twice is more desirable in language tests than offering just one opportunity. Using regression models, this study investigates, analyses and interconnects both item difficulty and stimulus length in relation to the frequency of stimulus presentation and its…

AAAS Project 2061 is collaborating with BSCS in the development a curriculum unit that connects core chemistry and biochemistry ideas in order to help eighth grade students build the conceptual foundation needed for high…

We evaluated the narrative and expository writing samples of 12 adolescents with language-learning disabilities (LLD) in Grades 6 to 12 for elements of microstructure (e.g., productivity, grammatical complexity) and macrostructure (genre-specific text structure elements) using an experimental measure. Writing samples were elicited with…

The potential of computer-based assessments for capturing complex learning outcomes has been discussed; however, relatively little is understood about how to leverage such potential for summative and accountability purposes. The aim of this study is to develop and validate a multimedia-based assessment of scientific inquiry abilities (MASIA) to…

The purpose of this study was to develop and gather validity evidence for silent reading fluency passages. A number of passages were written following a traditional story grammar structure (character, setting, events) and placed on a computer for students to read silently. We describe in detail, the manner in which content-related evidence was…

The purpose of this study was to document the instrument development of maze measures for grades 3-8. Each maze passage contained twelve omitted words that students filled in by choosing the best-fit word from among the provided options. In this technical report, we describe the process of creating, reviewing, and pilot testing the maze measures.…
