Accommodations for Students Who Are Deaf or Hard of Hearing in Large-Scale, Standardized Assessments: Surveying the Landscape and Charting a New Direction

Students who are deaf or hard of hearing (SDHH) often use test accommodations when they participate in large-scale, standardized assessments. The purpose of this article is to present findings from the Third Annual Survey of Assessment and Accommodations for Students who are Deaf or Hard of Hearing. The "big five" accommodations were reported by at least two-thirds of the 389 participants: extended time, small group/individual administration, test directions interpreted, test items read aloud, and test items interpreted. In a regression analysis, language used in instruction showed the most significant effects on accommodations use. The article considers these findings in light of a more proactive role for the National Survey in providing evidence for the effectiveness of accommodations with SDHH.     

Response to Intervention Screening and Progress‐Monitoring Practices in 41 Local Schools

This study describes response to intervention (RTI) screening and progress‐monitoring instruments and procedures in 41 local school settings. For screening the schools most often used published reading assessments or commercial products; a three‐times‐per‐year screening schedule was most prevalent. For progress monitoring schools most often relied on published reading assessments; a weekly progress monitoring schedule was most prevalent. The variability between local school practices is discussed with regard to efficiency, equity, and viability of RTI.     

Reading Progress Monitoring for Secondary‐School Students: Reliability,Validity, and Sensitivity to Growth of Reading‐Aloud and Maze‐Selection Measures

The validity and reliability of curriculum‐based measures in reading as indicators of performance and progress for secondary‐school students were examined. Thirty‐five grade 8 students completed reading aloud and maze‐selection measures weekly for 10 weeks. Criterion measures were the state standards test in reading and the Woodcock–Johnson III Test of Achievement. Different time frames for each measure were compared. Most alternate‐form reliability coefficients were above .80. Criterion‐related validity coefficients ranged from .77 to .89. No differences related to time were found. Only maze selection reflected significant growth, with an average increase of 1.29 correct choices per week. Maze growth was related to the reading performance level and to change on the Woodcock–Johnson III from pre‐ to posttest.     

Lighting the world with molecules

Efficient lighting and display have become important concerns in the energy-starved modern world. This has led to new paradigms in lighting and display technologies. Organic molecules provide a new class of active materials for such technologies. This article gives the basic science behind the design of such molecular materials used in displays and lighting.
