Recent implementation of Nebraska's Standards-based Teacher-led Assessment and Reporting System (STARS) introduced a unique opportunity to examine the benefits and drawbacks of a teacher-led state assessment system. STARS is unique among state assessment systems in that statewide tests are replaced by locally developed assessments designed by teachers. Benefits of this system are found to be greater teacher use of results for instructional planning, greater diagnostic utility of the assessments, and gains in assessment literacy. Disadvantages include the time-consuming and stressful nature of creating localized assessments. Compatibility of STARS with the requirements of the No Child Left Behind Act are discussed.  相似文献

The most frequently requested accommodation among students with learning disabilities (LD) in postsecondary settings is extended test time. The frequency with which this accommodation is requested and granted compels disability service providers to become knowledgeable about the factors that influence the need for, and appropriateness of, the accommodation. Moreover, the synthesis of these factors becomes the basis for determining if the accommodation is reasonable under federal law. The purpose of this article is to present a step‐by‐step model to be used as a decision‐making process when considering the accommodation of extended test time for postsecondary students with LD. The model is designed to assist disability service providers in the analysis and synthesis of information collected from (1) the student's diagnostic evaluation, (2) the course or classroom test to be accommodated, and (3) student interviews. A list of diagnostic tests from the four most frequently administered test batteries used with adults is provided, along with a concise explanation of how characteristics of LD impact reading, writing, and math, and relate to the need for extended time. This information can be used to determine if extended test time is a reasonable accommodation and to estimate how much additional time to provide.  相似文献

This study examined literacy instruction in 14 first‐grade classrooms of English learners (ELs) in three schools in a large urban school district in southern California over a two‐year period. Pre‐ and posttest measures of oral‐reading fluency for 186 first graders, representing 11 native languages, were the outcome data. Reading‐fluency data were examined in reference to ratings of literacy practices using the English Learners Classroom Observation Instrument (ELCOI). Results indicated a moderately strong correlation (r= 0.65) between ELCOI rating and gain in oral‐reading fluency at the end of first grade. We report patterns of ELs who read below the oral‐reading fluency benchmark thresholds and patterns of students who were ultimately labeled with learning disabilities. Instructional practices of teachers rated “high” and “low” are discussed. Educational implications and recommendations for future research are discussed.  相似文献
