The goal of the current study was to compare two forms of dynamic assessment and standard assessment of preschool children's phonological awareness. The first form of dynamic assessment was a form of scaffolding in which item formats were modified in response to an error so as to make the task easier or more explicit. The second form of dynamic assessment was direct instruction of the phonological awareness tasks. The results indicate that preschool children's phonological awareness can be assessed using standard assessment procedures, provided the items require processing units larger than the individual phoneme. No advantage was found in reliability or validity for either dynamic assessment condition relative to the standard assessment condition. Dynamic assessment does not appear to improve reliability or validity of phonological awareness assessments when preschool children are given tasks that they can perform using standard administration procedures.

The relative effectiveness of two computer-assisted instructional programs designed to provide instruction and practice in foundational reading skills was examined. First-grade students at risk for reading disabilities received approximately 80 h of small-group instruction in four 50-min sessions per week from October through May. Approximately half of the instruction was delivered by specially trained teachers to prepare students for their work on the computer, and half was delivered by the computer programs. At the end of first grade, there were no differences in student reading performance between students assigned to the different intervention conditions, but the combined-intervention students performed significantly better than control students who had been exposed to their school's normal reading program. Significant differences were obtained for phonemic awareness, phonemic decoding, reading accuracy, rapid automatic naming, and reading comprehension. A follow-up test at the end of second grade showed a similar pattern of differences, although only differences in phonemic awareness, phonemic decoding, and rapid naming remained statistically reliable.

The primary purpose of this longitudinal correlational study was to examine relations between phonological processing abilities and emerging individual differences in math computation skills and also to investigate the source of covariation between reading and math computation skills in a random sample (n = 201). Phonological memory, rate of access to phonological codes in long-term memory, and phonological awareness were uniquely associated with growth in estimated total number of computation procedures mastered (general computation skills) from 92.5 to 134.8 months in age, although the contributions of the first two abilities were developmentally limited. Phonological processing almost completely accounted for the associations between reading and general computation skills. Evidence of bidirectional relations between general computation skills and simple arithmetic problem solving speed was found.

The effectiveness of a phonologically based reading program delivered to first- through sixth-grade impaired readers in small groups (3–5) was examined. The 115 students from a predominantly low socioeconomic school were selected based on poor phonetic decoding and word-level reading skills, then matched and randomly assigned to one of two groups. The treatment group received the Spell Read program for eight weeks while the no-treatment control received only regular classroom reading instruction. At posttest-1 the treatment group performed significantly better than the controls on phonological awareness and decoding, reading accuracy, comprehension and spelling. Except for fluency, effect sizes were strong for most measures across all grades. Improved reading skills as a result of the phonological program were evident regardless of level of deficiency prior to instruction, and were not limited to specific grades. Outcome scores at posttest-2 after the control group was also given the Spell Read program indicated similar growth in reading. Results provide supportive evidence for small-group instruction as an effective remedial alternative for deficient readers.

Sixty children with severe reading disabilities were randomly assigned to two instructional programs that incorporated principles of effective instruction but differed in depth and extent of instruction in phonemic awareness and phonemic decoding skills. All children received 67.5 hours of one-to-one instruction in two 50-minute sessions per day for 8 weeks. Both instructional programs produced very large improvements in generalized reading skills that were stable over a 2-year follow-up period. When compared to the growth in broad reading ability that the participants made during their previous 16 months in learning disabilities resource rooms, their growth during the intervention produced effect sizes of 4.4 for one of the interventions and 3.9 for the other. Although the children's average scores on reading accuracy and comprehension were in the average range at the end of the follow-up period, measures of reading rate showed continued severe impairment for most of the children. Within 1 year following the intervention, 40% of the children were found to be no longer in need of special education services. The two methods of instruction were not differentially effective for children who entered the study with different levels of phonological ability, and the best overall predictors of long-term growth were resource room teacher ratings of attention/behavior, general verbal ability, and prior levels of component reading skills.

The aim of this longitudinal study was to further ourunderstanding of the reasons for social classdifferences in growth of decoding and readingcomprehension skills from beginning kindergarten throughchildren's fourth grade year. Participants wereenrolled in five public schools in a moderately sizedsouthern American city (n = 197). We examined ifbeginning kindergarten levels of three kinds ofreading related abilities explained social classdifferences in growth of reading skills during thetime periods of beginning kindergarten to children'sfirst-, second-, third-, and fourth-grade years. Thereading related abilities were phonological awareness,rate of access to phonological information inlong-term memory, and print knowledge. We found thatthe reasons for social class differences in growth ofreading skills depended on the time interval that wasconsidered. During the earliest time interval, socialclass differences in growth of decoding skills werecompletely accounted for by performance on the controlmeasures of general verbal intelligence and prior wordreading skills. During the remaining time periods,social class differences in growth of decoding andreading comprehension skills persisted whenperformance on the three kinds of reading relatedabilities and the control measures were accounted for. The greatest attenuation of SES differences in growthof reading skills occurred when beginning kindergartenlevels of print knowledge were taken into account.

The relative effectiveness of 3 instructional approaches for the prevention of reading disabilities in young children with weak phonological skills was examined. Two programs varying in the intensity of instruction in phonemic decoding were contrasted with each other and with a 3rd approach that supported the children's regular classroom reading program. The children were provided with 88 hr of one-to-one instruction beginning the second semester of kindergarten and extending through 2nd grade. The most phonemically explicit condition produced the strongest growth in word level reading skills, but there were no differences between groups in reading comprehension. Word level skills of children in the strongest group were in the middle of the average range. Growth curve analyses showed that beginning phonological skills, home background, and ratings of classroom behavior all predicted unique variance in growth of word level skills.

This article addresses questions about instruction for children with severe reading disabilities in 2 ways. First, outcomes from 3 recent studies are examined within the context of a hierarchy of instructional goals derived from current theory about the processes involved in acquisition of reading skill. This analysis suggests that we still have much to learn about effective instruction for children with the most severe reading disabilities. The second part of the article reports preliminary results from a 2½-year prevention project in which 138 children received instruction by 3 different methods. The primary instructional contrast involved the intensity and degree of explicitness of instruction in phonological awareness and phonetic decoding strategies for word reading. Results showed a clear advantage in phonetic reading ability for 1 group of children at the end of the second grade. However, this group did not show corresponding advantages in word-reading vocabulary or reading comprehension. The article concludes with a discussion of weaknesses in current research that suggest questions for future intervention studies.
