ABSTRACT

This study examined the efficacy of a kindergarten mathematics intervention program, ROOTS, focused on developing whole-number understanding in the areas of counting and cardinality and operations and algebraic thinking for students at risk in mathematics. The study utilized a randomized block design with students within classrooms randomly assigned to treatment or control conditions. Measures of mathematics achievement were collected in the fall (pretest) and spring (posttest) in kindergarten and in the winter of first grade (delayed posttest). Significant differences between conditions favoring treatment students were found on four of six measures at posttest. Treatment students reduced the achievement gap with their not-at-risk peers. No effect was found on follow-up first-grade achievement scores. Implications for Tier 2 mathematics instruction in a Response to Intervention model are discussed.  相似文献

This study compared the effects of Tier 2 reading interventions that operated in response‐to‐intervention contexts. Kindergarten children (N = 90) who were identified as at risk for reading difficulties were stratified by school and randomly assigned to receive (a) Early Reading Intervention (ERI; Pearson/Scott Foresman, 2004) modified in response to student performance or (b) their schools’ typical supplemental reading intervention (regrouping and curriculum pacing adjustments). In both conditions, intervention was provided 30 minutes per day in small groups for approximately 100 sessions. Results indicated no statistically significant group differences on any outcome measures. Between‐group effect sizes revealed substantively important differences (Valentine & Cooper, 2003) favoring the ERI responsive condition on multiple measures with effect sizes ranging from .35 to .59. Overall, findings indicated that the majority of students in both Tier 2 intervention conditions performed above the 30th percentile on posttest measures of word reading measures.  相似文献

Abstract

The goal of this study was to assess the effectiveness of an intervention—Quality English and Science Teaching 2—designed to help English language learners (ELLs) and their English proficient classmates develop academic language in science, as required by the Common Core State Standards. The intervention consisted of supplementary instructional materials and professional development. Participants included 1,309 students, of whom 353 were ELLs. Sixty sections taught by 15 teachers in seven middle schools were randomized within teacher to the intervention or the control condition. Treatment effects were tested separately for academic language and science knowledge. For the whole group, results indicated posttest differences favoring the treatment group sections were statistically significant for academic language and science. For ELLs however, posttest differences favored the treatment group for academic language only. Follow-up analyses investigating implementation found that treatment fidelity was related to gains in both academic language and science knowledge for the group as a whole and for ELLs. Effect sizes suggest the intervention was promising in promoting the academic language in science of both ELLs and their English proficient classmates.  相似文献

This study investigates the effects and feasibility of an intervention for first-grade students at risk for reading difficulties or disabilities (RD). The intervention was provided by general education classroom teachers and consisted of 15 min whole-class comprehension lessons (Tier 1) and 30 min Tier 2 intervention sessions in word reading, comprehension, and text reading. First-grade teachers (n = 21), with 4–5 students at risk for reading difficulties and potential reading disability were randomly assigned to treatment or typical practice comparison conditions. Significant group differences were detected on all measures of word reading, decoding, and fluency. Effect sizes were educationally important for all measures of word reading, decoding, and reading comprehension; however, effects on standardized measures were smaller than those in prior studies with similar students in which intervention was typically provided outside the regular classroom. An exploratory analysis indicated that students at different parts of the pretest and posttest distributions responded more and less positively to the intervention, providing insights that may help guide future revisions. The study provides preliminary evidence of the intervention's promise for positively impacting student outcomes.  相似文献

Previous studies have shown that instruction of reading strategies is an effective method for enhancing reading comprehension. However, many of the interventions in these studies focused on small groups of (poor) comprehenders and were provided by research assistants, making it time-consuming and relatively expensive. The authors implemented a strategy intervention to intact classrooms, consisting of reciprocal teaching and delivered by teachers. Participants were 510 typically developing fourth-grade students. A clustered randomized controlled trial was conducted with pretest, posttest, and follow-up measures to assess knowledge of reading strategies and reading comprehension. The results revealed that the intervention had an effect on knowledge of reading strategies at posttest and follow-up. However, the intervention did not affect reading comprehension performance. Together with the results of earlier studies, the present study raises the question whether strategy interventions are the most efficient to improve fourth-grade students' reading comprehension.  相似文献

Abstract

This research investigated the immediate and long-term effects of a Tier 2 intervention for beginning readers identified as having a high probability of reading failure using a randomized control trial. First-grade participants (n = 123) were randomly assigned either to a 25-session intervention targeting key reading components, including decoding, spelling, word recognition, fluency, and comprehension, or to a no-treatment control condition. Analyses of immediate posttests (end of first grade) indicated significant differences in measures of Decodable Word Fluency (effect size = .40) favoring the intervention group. Within the intervention group, tutor ratings of attention were significantly related to growth in Passage Reading Fluency and Spelling Fluency. Longitudinal assessments (end of second grade) indicated no significant differences by group. Analysis of responder status indicated that students defined as responders maintained gains to the end of second grade.  相似文献

This study evaluated a positive parenting program to Brazilian mothers who used corporal punishment with their children. The intervention was conducted in four agencies serving vulnerable children, and at a home replica laboratory at the University. Mothers who admitted using corporal punishment were randomly assigned between experimental (n = 20) and control group (n = 20). The program consisted of 12 individual sessions using one unit from Projeto Parceria (Partnership Project), with specific guidelines and materials on positive parenting, followed by observational sessions of mother-child interaction with live coaching and a video feedback session in the lab. The study used an equivalent group experimental design with pre/post-test and follow-up, in randomized controlled trials. Measures involved: Initial Interview; Strengths and Difficulties Questionnaire (SDQ) – parent and child versions; Beck Depression Inventory (BDI); observational sessions with a protocol; and a Program Evaluation by participants. Analysis of mixed models for repeated measures revealed significant positive effects on the BDI and SDQ total scores, as well as less Conduct problems and Hyperactivity in SDQ measures from the experimental group mothers, comparing pre with post-test. Observational data also indicated significant improvement in positive interaction from the experimental group mothers at post-test, in comparison with controls. No significant results were found, however, in children’s observational measures. Limitations of the study involved using a restricted sample, among others. Implications for future research are suggested.  相似文献

This article describes a field experiment with a pretest–posttest control group design which investigated the potential of reading picture books to children for supporting their mathematical understanding. The study involved 384 children from 18 kindergarten classes in 18 schools in the Netherlands. During three months, the children in the nine experimental classes were read picture books. Data analysis revealed that, when controlled for relevant covariates, the picture book reading programme had a positive effect (d = .13) on kindergartners’ mathematics performance as measured by a project test containing items on number, measurement and geometry. Compared to the increase from pretest to posttest in the control group, the increase in the experimental group was 22% larger. No significant differential intervention effects were found between subgroups based on kindergarten year, age, home language, socio-economic status and mathematics and language ability, but a significant intervention effect was found for girls and not for boys.  相似文献

We tested the effectiveness of the intervention program designed to enhance children's math motivation by simultaneously strengthening their growth mindsets and weakening their gender stereotypes. Both the intervention and control programs consisted of six bi-weekly 40-min sessions that were evenly distributed over three months and administered during regular school hours. Repeated measures analyses of variance with group (between-subject factor: intervention vs. control) and time (within-subject factor: pretest vs. posttest) revealed significant Group × Time interactions for all outcomes but test anxiety. Growth mindset, perceived competence, persistence, and achievement of the intervention group increased, while those of the control group decreased. Gender stereotypic beliefs exhibited the opposite pattern. Also, growth mindset and gender stereotypes correlated negatively only for the intervention group. Path analysis demonstrated that the growth mindset of students after the intervention predicted their math persistence and achievement directly and indirectly via their perceived competence in math.  相似文献

ABSTRACT

The authors’ purpose was to explore the effects of a supplementary, guided, silent reading intervention with 80 struggling third-grade readers who were retained at grade level as a result of poor performance on the reading portion of a criterion referenced state assessment. The students were distributed in 11 elementary schools in a large, urban school district in the state of Florida. A matched, quasi-experimental design was constructed using propensity scores for this study. Students in the guided, silent reading intervention, Reading Plus, evidenced higher, statistically significant mean scores on the Florida Comprehensive Assessment Test criterion assessment measure of reading at posttest. The effect size, favoring the guided, silent reading intervention group was large, 1 full standard deviation, when comparing the 2 comparison groups’ mean posttest scores. As such, the results indicate a large advantage for providing struggling third-grade readers guided silent reading fluency practice in a computer-based practice environment. No significant difference was found between the treatment and control group on the Stanford Achievement Test–10 (SAT-10) posttest scores, although posttest scores for the treatment group trended higher than the control. After conducting a power analysis, it was determined that the sample size (n = 80) was too small to provide sufficient statistical power to detect a difference in third-grade students’ SAT-10 scores.  相似文献

Research Findings: Within the flourishing area of research demonstrating the efficacy of emotion-based interventions carried out by trained teachers in educational contexts in increasing children’s emotional skills, this study makes an original contribution to the existing literature by focusing on the effects of this kind of intervention on toddlers’ prosocial and aggressive behavior. Ninety-five 26- to 36-month-olds participated in a 2-month intervention in which trained teachers read emotion-based stories to small groups of children and then either involved them in conversations about emotions (experimental condition) or did not (control condition). Even after we controlled for age and general language ability, the children in the experimental condition were found to outperform the control group on measures of emotion knowledge and emotional-state talk. Furthermore, the intervention fostered gains in prosocial behavior, whereas it did not have a significant effect on the frequency of aggressive actions, which was lower at posttest in both groups. The positive effect of the training program on participants’ prosocial behavior was no longer significant when we controlled for gains in emotion knowledge and emotional-state talk. Practice or Policy: The results encourage the implementation of early educational programs focused on emotion knowledge in order to foster children’s prosocial behavior toward peers.  相似文献

Abstract

This article reports the outcomes of an experimental evaluation of Read Well Kindergarten (RWK), a program that focuses on the development of vocabulary, phonological awareness, alphabetic understanding, and decoding. Kindergarten teachers in 24 elementary schools in New Mexico and Oregon were randomly assigned, by school, to teach RWK or their own program. Treatment teachers received 2 days of training and taught daily lessons. Project staff assessed 1,520 students at pretest and 1,428 at posttest with measures of vocabulary, phonological awareness, alphabetic understanding, and decoding. Follow-up testing was conducted in fall and spring of first grade. Analyses of final outcomes revealed a statistically significant difference favoring intervention students on curriculum-based measures of sight words and decodable words. Although these results did not generalize to standardized measures, follow-up analyses indicated that the impact of RWK rested on the rate of opportunities for independent student practice for letter names, letter sounds, sight words, and oral reading fluency, collected at the end of kindergarten. The findings suggest the potential efficacy of RWK in conjunction with frequent opportunities for independent practice for developing beginning reading skills.  相似文献

Abstract

We provide data 3 to 4 years postintervention for four samples of English language learners from two sequential Grade 1 cohorts who received supplemental Grade 1 reading interventions in Spanish or English and for whom the language of instruction for intervention was matched with language of core reading instruction. Participants were 300 students at risk for reading difficulties who were randomly assigned to intervention or comparison groups; there were 186 students from the four samples assessed in both languages (Spanish, English) 3 or 4 years after intervention completion (Spring Grade 4 or 5). Findings from the Spanish study revealed few statistically significant differences in favor of intervention students on Spanish measures, although effect sizes generally favored this group (median d = +0.33). Findings from the English study also revealed few statistically significant differences in favor of intervention students, though again, effect sizes were positive (median d = +0.23). Transfer effects were generally small, though nearly all were positive. Although the effects were small, receipt of intervention in Grade 1 was associated with clinically significant gains in a variety of literacy-related domains 3 to 4 years after the termination of supplemental instruction.  相似文献

The feasibility of creating a training program to facilitate the development of a generalized ability to use elaboration as an individual learning strategy was investigated. Seventy-five ninth graders were randomly assigned to a training/ experimental, control, or posttest-only group. Data analyses for the immediate posttest revealed significant mean differences favoring the experimental group on the free recall and Trial 2 of the paired-associate learning tasks. On the delayed posttest, significant differences favoring the experimental group were obtained for the reading comprehension task and Trial 1 of the serial learning task. These results provide evidence that students can be trained to use elaboration to enhance learning.  相似文献

The purpose of this study was to determine the effectiveness of an inquiry approach to science and language teaching to further develop classification and oral communication skills of bilingual Mexican American third graders. A random sample consisting of 64 subjects was selected for experimental and control groups from a population of 120 bilingual Mexican American third graders. The Solomon Four-Group experimental design was employed. Pre- and posttesting was performed by use of the Goldstein-Sheerer Object Sorting Test, (GSOST) and the Test of Oral Communication Skills, (TOCS). The experimental group participated in a sequential series of science lessons which required manipulation of objects, exploration, peer interaction, and teacher-pupil interaction. The children made observations and comparisons of familiar objects and then grouped them on the basis of perceived and inferred attributes. Children worked individually and in small groups. Analysis of variance procedures was used on the posttest scores to determine if there was a significant improvement in classification and oral communication skills in the experimental group. The results on the posttest scores indicated a significant improvement at the 0.01 level for the experimental group in both classification and oral communication skills. It was concluded that participation in the science inquiry lessons facilitated the development of classification and oral communication skills of bilingual children.  相似文献

Abstract

In this experimental study we examined the effects of integrating teacher-directed knowledge-building and student-regulated comprehension practices in 7th- to 10th-grade English language arts classes. We also investigated the effect of instructional quality and whether integrating practices differentially benefitted students with lower entry-level reading comprehension. The study was conducted in 6 schools, involving 17 teachers and 921 students. Teachers’ English language arts classes were randomly assigned to intervention (n = 36) or typical practice comparison (n = 29) conditions, and all teachers taught in both conditions. Students in both conditions grew significantly from pretest to posttest on proximal measures of narrative (ES =.09) and expository comprehension (ES =.22), as well as a standardized distal comprehension measure (ES =.46); however, no statistically significant between-group differences were found. Although intervention fidelity did not significantly influence outcomes, observational data indicated that teachers increasingly incorporated comprehension practices in their typical instruction. Effect sizes indicated a differential influence of entry-level reading comprehension on proximal and distal comprehension with higher performing readers in the intervention condition benefiting more than their lower performing peers on expository comprehension.  相似文献

In typical development, gestures precede and predict language development. This study examines the developmental sequence of expressive communication and relations between specific gestural and language milestones in toddlers with autism spectrum disorder (ASD), who demonstrate marked difficulty with gesture production and language. Communication skills across five stages (gestures, word approximations, first words, gesture-word combinations, and two-word combinations) were assessed monthly by blind raters for toddlers with ASD participating in an randomized control trial of parent-mediated treatment (N = 42, 12–30 months). Findings revealed that toddlers acquired skills following a reliable (vs. idiosyncratic) sequence and the majority of toddlers combined gestures with words before combining words in speech, but in contrast to the pattern observed in typical development, a significant subset acquired pointing after first words.  相似文献

ABSTRACT

The purpose of this set of analyses, conducted on a randomized control trial examining the effects of a fourth-grade fraction intervention, was to assess the initial academic deficit severity hypothesis. With this hypothesis, at-risk students with more severe initial academic deficits are expected to profit less from intervention than do students with less severe initial academic deficits. Moderation analyses indicated that students with varying degrees of initial academic deficits benefited comparably from the intervention, such that effect sizes comparing intervention against control students were similar across the range of initial academic deficits. In a similar way, across the range of initial academic deficits, intervention students' posttest (spring) calculation performance was normalized (one standard error of measurement above the 25th percentile of a not-at-risk normative group's spring performance). On the most distal fractions outcome, however, normalized performance was achieved for intervention students with less severe initial academic deficits. Findings are discussed in terms of methods for judging intervention efficacy and for making individual decisions about when students should exit intervention.  相似文献
