According to the National Assessment of Educational Progress (NAEP), the average 17-year-old today is no more proficient at reading or mathematics than his counterpart in 1970. Some progress has been made by 9- and 13-year-olds, but the gains evaporate by the time these students reach the end of their K-12 experience. The average 17-year-old…

This study compares 2 measures of reading comprehension: (a) the Woodcock-Johnson Passage Comprehension test, a standard in reading research, and (b) the Diagnostic Assessment of Reading Comprehension (DARC), an innovative measure. Data from 192 Grade 3 Spanish-speaking English language learners (ELLs) were used to fit a series of latent variable…

Although testing accommodations are commonly provided to students with disabilities within large-scale testing programs, research findings on how well accommodations allow for comparable measurement of student knowledge and skill remain inconclusive. The purpose of this study was to examine the extent to which 1 commonly held belief about testing…

This research examined component processes that contribute to performance on one of the new, standards-based reading tests that have become a staple in many states. Participants were 60 Grade 4 students randomly sampled from 7 classrooms in a rural school district. The particular test we studied employed a mixture of traditional (multiple-choice)…

The purpose of this study was to assess the efficacy and practicality of precision reading, a constructive reading intervention, with students with cognitive impairments, extreme academic deficits in reading, and severe social, emotional, and psychiatric problems. As precision reading had shown promise with students with low achievement, learning…

The author was startled by the carelessness and selectivity of Robert Slavin's comments, which give his words the ring of a promotional release rather than of intellectual reflection. He agrees that Slavin is accurate in saying that the scores on reading tests at P.S. 65 in the South Bronx improved during a period in which, among a number of other…

Experiments that assign intact groups to treatment conditions are increasingly common in social research. In educational research, the groups assigned are often schools. The design of group-randomized experiments requires knowledge of the intraclass correlation structure to compute statistical power and sample sizes required to achieve adequate…

The causal effects of a voluntary summer reading intervention on children's reading activities and reading achievement were assessed in a randomized experiment involving 331 children in Grades 1-5. Children were pretested in the spring on a standardized test of reading achievement (Stanford Achievement Test, 10th ed.), on the Elementary Reading…

Mounting pressure in the policy arena to improve teacher productivity either by improving signals that predict teacher performance or through creating incentive contracts based on performance--has spurred two related questions: Are there important determinants of teacher productivity that are not captured by teacher credentials but that can be…

The "District of Columbia School Choice Incentive Act of 2003," passed by the Congress in January 2004, established the first federally funded, private school voucher program in the United States. The purpose of the new scholarship program was to provide low-income residents, particularly those whose children attend schools in need of…

Reading Recovery is part of the Every Child a Reader strategy to enable children to make a good start in reading. Reading Recovery is well known to have impressive effects in the shorter term, but less is known about its long-term effectiveness. The present study followed up at the end of Year 4: 120 comparison children, 73 children who had…

A cost-effectiveness analysis was conducted of Gordon, Kane, and Staiger's (2006) proposal to raise student achievement by identifying and replacing the bottom quartile of novice teachers, using value-added assessment of teacher performance. The cost effectiveness of this proposal was compared to the cost effectiveness of voucher programs, charter…

The "District of Columbia School Choice Incentive Act of 2003," passed by the Congress in January 2004, established the first federally funded, private school voucher program in the United States. The purpose of the new scholarship program was to provide low-income residents, particularly those whose children attend schools in need of…

A comparison of achievement and personal adjustment of Spanish-speaking students in an experimental bilingual school environment at the first grade level was the purpose of the Harlandale instructional project. This evaluation report presents comparative data from the testing program used to establish the effectiveness of bilingual education when…

It has been reasonably well established that test takers can sometimes answer correctly some reading comprehension passages without reading the passages on which the questions are based. This issue was studied with the new Scholastic Aptitude Test (SAT) in a study designed to determine the strategies by which examinees are able to achieve…
