This study examined the cost-effectiveness of a 50-lesson mathematics intervention program focused on whole number concepts for at-risk kindergarten students, ROOTS. The study utilized a randomized...

A concerning number of students enter kindergarten facing an intractable variation of mathematics difficulties (MD). This study investigated the impact of an explicit, core kindergarten mathematics program on the mathematical outcomes of kindergartners who demonstrated risk for severe MD at kindergarten entry and examined whether these students improved from a category of high MD risk (i.e.

This pilot study examined the promise of a Tier 2 Grade 6 intervention program for students at risk for difficulties in mathematics. The study utilized a quasi-experimental design. The final sample included 112 students in treatment (Promoting Algebra Readiness) and 86 students in control (standard district practice) conditions. The Promoting Algebra Readiness program consisted of 93 lessons across four strands focused on key concepts and applications of fractions. Measures of mathematics achievement were collected at pretest and posttest. Feasibility and usability data indicated favorable impressions by users and strong levels of implementation fidelity. Gain scores of treatment students were significantly greater than those of control peers on two of four proximal measures of mathematics achievement. Positive nonsignificant effects were found on additional proximal and distal measures. Implications for educators delivering instruction for at-risk students in multitier service delivery models are discussed.

States are increasingly recommending that districts and schools use multi-tiered systems of support (MTSS) to improve reading outcomes for all students. States have also suggested MTSS is a viable service delivery model in response to new state legislation to screen, identify, and treat students with word-level reading disability (i.e., dyslexia). One model of MTSS that utilizes Enhanced Core Reading Instruction (ECRI MTSS), has demonstrated significant increases in students’ early acquisition of foundational reading skills (Smith et al., 2016). The purpose of this study was to conduct a conceptual replication of the Smith’s (2016) original impact study. In a cluster-randomized controlled trial, 44 schools were randomly assigned to the ECRI MTSS treatment or a business-as-usual (BAU) MTSS control condition. Across conditions, 754 students were assigned to receive Tier 2 intervention in addition to Tier 1 instruction. Impact data indicate moderate to strong effects on student decoding, word reading, and fluency skills for students in the ECRI MTSS schools. Results suggest that schools can use ECRI MTSS to improve foundational reading skills for struggling early readers, including students with or at risk for word-level reading disabilities (i.e., dyslexia).

This study examined whether the efficacy of ROOTS, a 50-lesson mathematics intervention program focused on whole number concepts for at-risk kindergarten students, differed by group size an...

One commonly used strategy used in attempts to decrease racial disproportionality in school discipline across the country is sharing data with school administrators that discipline disparities are a problem in their schools with the assumption that it will increase attention to equity and improve outcomes. The purpose of this study was to assess the effects of providing monthly disciplinary equity reports to school administrators in 35 schools on levels of (a) disciplinary equity report viewing, (b) disciplinary equity, and (c) inclusion of disciplinary equity into school improvement plan goals. We used a small, double-blind randomized controlled trial in which half of the schools were randomly assigned to receive either monthly disciplinary equity reports or monthly general discipline reports. Results showed that schools receiving the equity reports had significantly increased rates of viewing equity reports but no meaningful change in disciplinary equity or equity goal setting.

Instructional interactions that occur between teachers and students around foundational mathematics topics are critical for supporting mathematical proficiency among students with mathematics learning disabilities (MLD). This study investigated whether the initial mathematics skill of 880 kindergarten students at risk of MLD predicted the quantity and quality of explicit instructional interactions (i.e., overt teacher modeling, student practice opportunities, and academic feedback) experienced during an empirically validated Tier 2 kindergarten mathematics intervention. It also examined whether the quantity and quality of such instructional interactions predicted gains in student mathematics achievement. Researchers conducted 740 direct observations of 255 intervention groups within a multiyear, randomized controlled trial. Results suggested that intervention groups with lower initial mathematics skill received higher rates of academic feedback and made more frequent errors. In addition, more frequent and higher quality academic feedback and group practice opportunities predicted increased mathematics achievement. Implications for investigating the active ingredients of mathematics interventions are discussed.

Universal screening is a critical component of school-based prevention systems. Screening data enable educators to target students for supplemental intervention, align resources to meet needs, and identify students who may be at risk for learning disabilities. One major requirement of the screening process is that all students are included to gain an accurate picture of school performance. It is therefore surprising that few evaluations of screening systems have focused on English language measures and their use with English learners. In this article, we aim to evaluate common screening thresholds, 54 across Grades k–3, to determine the extent to which they may differ between English learners and English proficient students. Results indicate that many thresholds are consistent between groups with some exceptions in kindergarten. We discuss implications for screening assessment and decision making but suggest that similar cut scores across groups do not imply similar intervention strategies.

Well-designed mathematics instruction focused on concepts and problem-solving skills associated with measurement and data analysis can build a foundational understanding for more advanced mathematics. This study investigated the efficacy of the Precision Mathematics Level 1 (PM-L1) intervention, a Tier 2 print- and technology-based mathematics intervention designed to increase first-grade students’ conceptual understanding and problem-solving skills around the areas of measurement and data analysis. Employing a randomized controlled trial, 96 first-grade students at risk for mathematics difficulties were randomly assigned within classrooms to either a treatment (PM-L1) or a control (business-as-usual) condition. A statistically significant positive effect was found on one of five outcome measures, with the other four showing positive but nonsignificant results. Results also suggested preliminary evidence of differential response based on students’ number sense and early literacy risk status. Implications for using mathematics interventions focused on measurement and data analysis to build comprehensive, multitiered service delivery models in mathematics are discussed.

Oregon’s Effective Behavioral and Instructional Support Systems (EBISS) initiative was implemented in 25 school districts. The initiative trained and coached district leaders and teachers in the use of the EBISS model through the lens of implementation science. The EBISS model integrates school-wide positive behavior intervention and supports (SWPBIS) and the school-wide reading model (SWRM) to improve schools for all students and to reduce the number of students at risk of learning difficulties. Proximal outcomes included gains in the number of building-level SWPBIS and SWRM implementation teams and the activities of those teams. Distal outcomes included statistically significant gains in oral reading fluency (ORF) in first and third grades and marginally significant decreases in the percentage of students in the intensive category for reading in second and fourth grades. These findings suggest that to optimize improvements in teacher and student outcomes, a rigorous system of professional development and coaching appears necessary.

In this overview of implementation science and implementation fidelity in the field of learning disabilities, authors provide a brief summary of current research related to implementation science followed by an introduction of the articles in this special series. Authors emphasize the relationship between the effectiveness of interventions and the difficulty of their implementation, highlighting the importance of considering both when adopting new interventions in the field of learning disabilities. The authors then turn their attention to the need for implementation science and implementation fidelity to be considered at all stages of research from program or intervention development to efficacy and effectiveness trials through large-scale implementation in real-world settings. An overview of active implementation frameworks as proposed by the National Implementation Research Network as well as a discussion on the importance of research–practice partnerships when implementing programs and interventions in the field of learning disabilities are also included.

English learners (ELs) represent a rapidly growing subgroup in US schools. Yet, converging evidence suggests that a concerning number of ELs struggle to reach proficient levels in mathematics. The purpose of this multi-site randomized controlled trial was to examine the treatment effects of a Tier 2 mathematics intervention on the mathematical outcomes of kindergarten ELs with mathematics difficulties (MD). Additionally, recognizing that students differently benefit from early mathematics interventions, the study also examined whether specific student-level variables predicted ELs’ differential response to the intervention. A total of 295 ELs from 138 kindergarten classrooms participated in the study. Findings indicated overall treatment effects on five mathematics outcome measures. Results also suggested that the intervention worked equally well across a diverse sample of at-risk ELs with varying mathematics skills and English proficiency levels. Implications in terms of using principles of explicit instruction to improve the design of mathematics interventions and furthering the knowledge base of effective instruction for ELs with MD are discussed.

Implementation of evidence-based practices (EBPs) is paramount to students’ development of mathematics proficiency. This study investigated “practice-based evidence” of interventionists’ actual use of explicit mathematics instruction, a well-established EBP. Specifically, this study analyzed direct observation data collected in a federally funded efficacy trial involving a Tier 2 first-grade mathematics intervention to examine whether the quantity and quality of explicit mathematics instruction was associated with the mathematics outcomes of 470 first-grade students with or at risk for mathematics learning disabilities. Associations between group-level pretreatment skill levels and the quality and quantity of explicit mathematics instructional practices used in the intervention were also explored. Findings suggested significant associations between positive gains in student mathematics outcomes and (a) lower rates of incorrectly answered mathematics-focused questions, and (b) the rate in which interventionists delivered group-level practice opportunities and offered academic feedback. Significant associations were also found between initial student mathematics performance and rates of student errors and the quality of explicit instruction. Implications for using direct observation to document enacted EBPs are discussed.

This study examined the role of initial skill in moderating intervention effects of a 50-lesson mathematics intervention program, ROOTS, for at-risk kindergarten students focused on developing whole-number concepts and skills. The study utilized a randomized block design with at-risk students ( n = 592) within classrooms ( n = 60) randomly assigned to one of two treatment conditions (a small group of two to five students) or control condition. Proximal and distal measures were collected in the fall (pretest), spring (posttest), and winter of first grade (delayed posttest). Analyses examined the moderating effects of initial student achievement level on mathematics outcomes. Results indicated that initial skill moderated student outcomes but the relationship did not differ by group size. Implications for tiered mathematics instruction are discussed.

Group size and treatment intensity are understudied topics in mathematics intervention research. This study examined whether the treatment intensity and overall intervention effects of an empirically validated Tier 2 mathematics intervention varied between intervention groups with 2:1 and 5:1 student-teacher ratios. Student practice opportunities and the quality of explicit instruction served as treatment intensity metrics. A total of 465 kindergarten students with mathematics difficulties from 136 intervention groups participated. Results suggested comparable performances between the 2:1 and 5:1 intervention groups on six outcome measures. Observation data indicated that student practice differed by group size. Students in the 5:1 groups received more opportunities to practice with their peers, while students in the 2:1 groups participated in more frequent and higher quality individualized practice opportunities. Implications in terms of delivering Tier 2 interventions in small-group formats and engaging at-risk learners in meaningful practice opportunities are discussed.

The present study examined the extent to which racial disproportionality in office discipline referrals (ODRs) exists between American Indian/Alaska Native (AIAN) and White students in elementary ( n = 140), middle ( n = 67), and high ( n = 48) schools. A multilevel logistic regression model was applied to examine overall levels of ODR disproportionality. For school levels with significant disproportionality, patterns of ODRs were analyzed to examine disproportionality of subjectively defined ODRs within the contexts of (a) student ethnicity, (b) time of day, (c) location, (d) severity of problem behavior, and (e) student gender. Results showed a sizable difference in subjective ODRs between AIAN and White students at the high school level.

A growing body of research suggests that the effects of core mathematics instruction on student mathematics outcomes may not be uniform across different skill levels in mathematics. This study investigated the extent to which observed components of explicit mathematics instruction explained why students’ initial mathematics achievement was previously found to moderate the treatment impact of an empirically validated, core kindergarten mathematics program. Instructional components examined were as follows: (a) teacher demonstrations and explanations of mathematical concepts, (b) group and individual student practice opportunities, and (c) teacher-delivered academic feedback. Findings suggest that the rate in which teachers facilitated individual student practice opportunities during core mathematics instruction explained the program’s differential effectiveness. Implications in terms of differentiating practice opportunities for at-risk learners and utilizing classroom observation data to test potential mediating variables of academic interventions are discussed.

Accumulating research has established explicit mathematics instruction as an evidence-based teaching practice. This study utilized observation data from a multi-year efficacy trial to examine the longitudinal effects of a core kindergarten mathematics program on the use of explicit mathematics instruction among two distinct groups of teachers: one group that used standard practices in Year 1 of the efficacy trial and the core program in Year 2, and a second group that used the core program in both years. Targeted teaching practices consisted of teacher models, student practice opportunities, and teacher-provided academic feedback. Implementation of the program in Year 2 was found to increase the mean rates of teaching practices of teachers who used standard teaching practices in Year 1. Effect sizes are also suggestive of a positive impact of a second year of implementation with the core program. Implications for designing explicit mathematics programs and investigating evidence-based practices in future research are discussed.

This study examines measurement of creative ideational behaviors alongside factors of student engagement that may play a role in the development of students’ creative potential during early adolescence in school. Two studies used exploratory and confirmatory factor analyses, cross-validation, and invariance testing of 2 extant measures with multiple samples of 6th grade students in the United States. Key findings show that reduced versions of the Runco Ideational Behavior Scale for Students (RIBS-C) and the student engagement instrument (SEI) demonstrated a close fit to the data and sufficient evidence of reliability and validity. In addition, flexibility in creative ideation showed consistently high correlations with relational support with peers and teachers and educational aspiration and relevance. Results provide greater precision for future measurement and support for developmental and sociocultural theories of creativity in the learning environment. This study also reinforces the cognitive perspecti...

We report on a practitioner implementation of Fusion, a first-grade mathematics intervention. Studies such as this evaluation of a loose implementation under realistic conditions are important to curriculum developers’ understanding of how evidence-based programs and tools work under a variety of implementation scenarios. In this quasi-experimental study, first-grade students ( n = 253) in 10 schools were assigned to treatment ( n = 154) or control ( n = 99). Rather than randomly assigning students, schools assigned those students most at risk to treatment and, typically, those less at risk to control. School staff administered pre- and postassessments and led Fusion sessions approximately 30 min per day, 3 days per week. The intervention resulted in a significant positive effect on a researcher-developed first-grade math measure. The implementation of Fusion and feedback from school staff provided insights to guide the curriculum development process.

The purpose of this replication study was to examine the impact of the Teacher Study Group (TSG) professional development in vocabulary on first-grade teachers' knowledge of vocabulary instruction and observed teaching practice, and on students' vocabulary knowledge. Sixty-two schools from 16 districts in four states were randomly assigned to treatment and control conditions. A total of 182 first-grade teachers and their 1,811 students formed the sample. Treatment teachers received the TSG professional development from October to March. Teachers in the business-as-usual control condition received school/district professional development. A multilevel analysis was conducted to detect impacts. Significant impacts were found for teacher knowledge and observed teaching practice. No impacts were found at the student level.

This study investigated the psychometric properties of the Elementary Social Behaviour Assessment (ESBA), a teacher-report measure of students’ social skills and academic engagement adapted for use in Norwegian schools. At two times, 8 weeks apart, 151 teachers rated 793 students in Grades 1–6 on the ESBA and the Social Skills Rating System Teacher’s form (SSRS-T). Exploratory factor analysis with the first assessment suggested one or possibly two factors. Confirmatory factor analysis with the second assessment confirmed the one- or two-factor models but did not offer strong evidence for one over the other. The ESBA demonstrated good to excellent reliability. Strong concurrent and predictive correlations with the SSRS-T established criterion validity. The school and teacher levels explained only a limited amount of the total variance in ESBA scores, suggesting that teachers rate students quite similarly. The Norwegian-adapted ESBA paralleled the reliability and validity evidence from US samples.

Research Findings: This observation study investigated the prevalence and correlates of learning contexts provided to preschool-age children in 133 registered child care homes in below-average-income neighborhoods in the U.S. Pacific Northwest. On average, 30% of the observed proportion of time was spent in structured teacher-led activities, 51% in free-choice activities, 10% in routine activities, 1% in watching video/TV, and 7% in transition. Home-based child care providers gave significantly more positive recognition during structured teacher-led activities, and children engaged in more prosocial behavior during free-choice time. Directives and noncompliance occurred more often during transitions. A higher child-to-caregiver ratio was associated with more time spent in free-choice time, and caregiver experience and education were not associated with the time spent in specific learning contexts. Practice or Policy: Similar to preschool and center-based child care, current practice in home-based ...

Opportunities for practice play a critical role in learning complex behaviors. In the context of explicit mathematics instruction, practice facilitates systematic opportunities for students with mathematics difficulties (MD) to learn new mathematics content and apply such knowledge and skills to novel mathematics problems. This study explored whether there is an optimal amount of student practice that teachers should provide in core mathematics instruction to maximize the mathematics achievement of kindergarten students with MD, a so called “Goldilocks effect,” as opposed to simply “more is better.” Results from observation data collected in a large-scale efficacy trial supported the latter rather than the former. Specifically, we found that three individual practice opportunities for every explicit teacher demonstration of mathematical content was associated with increased mathematics achievement for students with MD relative to fewer practice opportunities. Implications for facilitating frequent student practice opportunities during core mathematics instruction and designing professional development for teachers who work with students with MD are discussed.

This study evaluated the long-term impact of schoolwide positive behavioural interventions and supports (PBIS) on student academic achievement. In this quasi-experimental study, academic achievement data were collected over 9 years. The 21 elementary, middle, and high schools that achieved moderate to high fidelity to the Save & Civil Schools’ PBIS model were matched with 28 control schools to assess academic gains. There were 5 years of baseline data (no intervention in treatment schools) and 4 years of intervention data, including 1 year of maintenance. Results indicate that implementation of the PBIS programme was significantly associated with increased student academic achievement (p = .001) and that the rate of change for students’ academic achievement in treatment schools was greater than for students in control schools. This study suggests that PBIS programmes, such as Safe & Civil Schools’ Foundations, may complement other efforts to improve academic outcomes.

The purpose of this closely aligned conceptual replication study was to investigate the efficacy of a Tier 2 kindergarten mathematics intervention. The replication study differed from the initial randomized controlled trial on three important elements: geographical region, timing of the intervention, and instructional context of the counterfactual. Similar to the original investigation, however, the current study tested the same intervention, used the same outcome measures and statistical analyses, and involved the same population of learners. A total of 319 kindergarten students with mathematics difficulties from 36 kindergarten classrooms participated in the study. Students who were randomly assigned to the treatment condition received the intervention in small-group formats, with 2 or 5 students per group. Control students participated in a no-treatment control condition. Significant effects on proximal and distal measures of mathematics achievement were found. Effect sizes obtained for all measures fell within or exceeded the upper bound of the effects reported in the initial study. Implications for systematically situating replication studies in larger frameworks of intervention research and reporting rates of treatment response across replication studies are discussed.

There is a dearth of research on Tier 1 instruction designed to improve the mathematics achievement of English learners. This study examined the impact of a core kindergarten mathematics curriculum on the mathematics achievement of Spanish-speaking English learners (SS-ELs). Secondary aims tested for differential response to the curriculum among SS-ELs as a function of (a) mathematics skills at the beginning of kindergarten, (b) the number of SS-ELs in classrooms, and (c) the frequency of mathematical discourse during core mathematics instruction. Data analyzed in the study were generated from a recent large-scale efficacy trial. Participants were 556 SS-ELs from 66 kindergarten classrooms. Results suggest SS-ELs in treatment classrooms made greater gains than SS-ELs in comparison classrooms on mathematics measures across the school year. Evidence of differential response to the curriculum among SS-ELs was not found. The importance of core mathematics instruction and implications for school psych...

This study examines the effect of 30 min of small group explicit instruction on reading outcomes for first-grade Spanish-speaking English learners (ELs) at risk of reading difficulties. Participants were 78 ELs from seven schools who were receiving Spanish only, or Spanish and English, whole group reading instruction in first grade. Students were rank-ordered within schools and then randomly assigned to a treatment condition ( n = 39) or a comparison condition ( n = 39). Students in the treatment condition received instruction on transition elements that supported their transfer of skills from Spanish to English. Students in the comparison condition received Business as Usual instruction from a variety of commercially available programs. Findings indicated that ELs in both conditions made significant gains from pretest to posttest on all reading outcomes even though instruction in the treatment condition focused significantly more on higher order skills (i.e., vocabulary, comprehension, and transition elements) whereas instruction in the comparison condition focused significantly more on lower order skills (i.e., phonics, word work, and sentence reading). Implications for practice and future research are discussed.

A critical aspect of intervention research is investigating the active ingredients that underlie intensive interventions and their theories of change. This study explored the rate of instructional interactions within treatment groups to determine whether they offered explanatory power of an empirically validated Tier 2 kindergarten mathematics intervention. Direct observations were conducted in 46 interventions groups, involving approximately 228 students. Multilevel structural equation models revealed that fall mathematics achievement significantly and negatively predicted the rate of academic feedback. Specifically, intervention groups with lower student mathematics achievement at the start of the kindergarten year received higher rates of academic feedback. Analyses also suggested that latent rates of instructional interactions were not significantly correlated with gains on student mathematics outcomes. Implications are discussed in relation to specifying the underlying mechanisms to intensify mathematics interventions, documenting local adaptation of intervention implementation, and examining possible threshold effects of instructional interactions.

Racial disparities in rates of exclusionary school discipline are well documented and seemingly intractable. However, emerging theories on implicit bias show promise in identifying effective interventions. In this study, we used school discipline data from 1,666 elementary schools and 483,686 office discipline referrals to identify specific situations in which disproportionality was more likely. Results were largely consistent with our theoretical model, indicating increased racial and gender disproportionality for subjectively defined behaviors, in classrooms, and for incidents classified as more severe. The time of day also substantially affected disproportionality. These findings can be used to pinpoint specific student-teacher interactions for intervention.

This study reports the results of a cluster RCT evaluating the impact of Enhanced Core Reading Instruction on reading achievement of grade 1 at-risk readers. Forty-four elementary schools, blocked by district, were randomly assigned to condition. In both conditions, at-risk readers received 90 minutes of whole-group instruction (Tier 1) plus an additional 30 minutes of daily, small-group intervention (Tier 2). In the treatment condition, Tier 1 instruction included enhancements to the core program and Tier 2 intervention was highly aligned with the core program. In the comparison condition, Tier 1 instruction used the same core program as treatment schools in the district and Tier 2 intervention followed standard district protocol. Significant treatment effects were found on measures of phonemic decoding and oral reading fluency from fall to winter and word reading from fall to spring. Student- and classroom-level variables predicted student response to instruction differentially by condition.

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.

The purpose of this study was to investigate the incremental validity of a set of domain general cognitive measures added to a traditional screening battery of early numeracy measures. The sample consisted of 458 kindergarten students of whom 285 were designated as severely at-risk for mathematics difficulty. Hierarchical multiple regression results indicated that Wechsler Abbreviated Scales of Intelligence (WASI) Matrix Reasoning and Vocabulary subtests, and Digit Span Forward and Backward measures explained a small, but unique portion of the variance in kindergarten students' mathematics performance on the Test of Early Mathematics Ability-Third Edition (TEMA-3) when controlling for Early Numeracy Curriculum Based Measurement (EN-CBM) screening measures (R² change = .01). Furthermore, the incremental validity of the domain general cognitive measures was relatively stronger for the severely at-risk sample. We discuss results from the study in light of instructional decision-making and note the findings do not justify adding domain general cognitive assessments to mathematics screening batteries.

This comprehensive evaluation of the Dynamic Indicators of Basic Early Literacy Skills Sixth Edition (DIBELS6) set of measures gives a practical illustration of signal detection methods, the methods used to determine the value of screening and diagnostic systems, and offers an updated set of cut scores (decision thresholds). Data were drawn from a sample of 13,507 English-proficient students in kindergarten through Grade 3, with more than 4,500 students per grade level. Results indicate that most DIBELS6 measures accurately predict comprehensive test performance and that previously published decision thresholds for DIBELS6 are generally appropriate with some key exceptions. For example, the performance of phoneme segmentation fluency did not always meet expectations. The revised DIBELS6 decision thresholds can satisfactorily identify students who may require additional supports.

Objective: In order to improve our understanding of where to target interventions, the study examined the extent to which school discipline disproportionality between African American and White students was attributable to teachers’ decisions regarding subjectively versus non-subjectively defined behaviors. Method: The sample consisted of office discipline referral (ODR) records for 1,154,686 students enrolled in 1,824 US schools. Analyses compared the relative contributions of disproportionality in ODRs for subjectively and objectively defined behaviors to overall disproportionality, controlling for relevant school characteristics. Results: Results showed that disproportionality in subjective ODRs explained the vast majority of variance in total disproportionality. Conclusions: These findings suggest that providing educators with strategies to neutralize the effects of implicit and other subtle forms of bias, which are known to influence ambiguous and discretionary decisions, may be a promising avenue for achieving equity in school discipline.

With the increased number of schools adopting social-emotional learning (SEL) programming, there is increased emphasis on the role of implementation in obtaining desired outcomes. Despite this, the current knowledge of the active ingredients of SEL programming is lacking, and there is a need to move from a focus on "whether" implementation matters to "what" aspects of implementation matter. To address this gap, the current study utilizes a latent class approach with data from year 1 of a randomized controlled trial of Second Step® (61 schools, 321 teachers, over 7300 students). Latent classes of implementation were identified, then used to predict student outcomes. Teachers reported on multiple dimensions of implementation (adherence, dosage, competency), as well as student outcomes. Observational data were also used to assess classroom behavior (academic engagement and disruptive behavior). Results suggest that a three-class model fits the data best, labeled as high-quality, low-engagement, and low-adherence classes. Only the low-engagement class showed significant associations with poorer outcomes, when compared to the high-quality class (not the low-adherence class). Findings are discussed in terms of implications for program development and implementation science more broadly.

This article presents the results of an evaluation of Positive Family Support, an ecological family intervention and treatment approach to parent supports and family management training developed from a history of basic and translational research. This effectiveness trial, with 41 public middle schools randomly assigned to intervention or control, examined student-, teacher-, and parent-reported outcomes, as well as math and reading scores and school attendance. Multilevel analyses suggested that for students at risk for behavior problems, immediate-intervention schools outperformed control schools on parent-reported negative school contacts for students at risk for behavior problems. Implementation, however, was hampered by several challenges, including school funding cuts, lack of staff time to provide parenting supports, and staff turnover. Given that preventive interventions are generally cost effective, it is critical that researchers continue their efforts to refine these interventions and find ways to support schools' implementation of evidence-based programs that can reduce problem behavior. This article is part of a special issue "Parental Engagement in School-Based Interventions".

This study reported findings from a longitudinal randomized controlled trial of Carescapes, a professional development program for home-based child-care providers in promoting children's social competence. Participants included 134 child-care providers and 310 children, ages 3-5 years, in Oregon. The Carescapes intervention group made significant improvements in observed caregiver responsiveness and monitoring, and showed decreased caregiver-reported child problem behavior and improved parent-reported peer relationships compared to the control group. Increased caregiver-reported cooperation skills were found for the intervention group at follow-up. No differences in condition were found for kindergarten teacher-reported social-behavioral, classroom, and academic skills. Moderation effects on children's behavior and peer relations were found for child age and exposure to the intervention child care.

This article describes a follow-up study that experimentally evaluated the effects of supplemental reading instruction for children in kindergarten through Grade 3. Students from 10 elementary schools in three school districts were screened using the Dynamic Indicators of Basic Early Literacy Skills. Two hundred fifty-six K—2 students were identified for participation, then randomly assigned to receive or not receive 2 years of supplemental reading instruction that taught basic decoding and comprehension skills. Reading ability was measured in the fall prior to the first year of the intervention and again in the spring of Years 1, 2, and 3. At the end of the 2-year intervention, children who received the supplemental instruction performed better on measures of word attack, word identification, oral reading fluency, vocabulary, and reading comprehension. One year after the intervention, children in the supplemental instruction group still showed greater improvement in word attack and oral reading fluency than the comparison students.

This study examined the efficacy of a Tier 2 kindergarten mathematics intervention program, ROOTS, focused on developing whole number understanding for students at risk in mathematics. A total of 29 classrooms were randomly assigned to treatment (ROOTS) or control (standard district practices) conditions. Measures of mathematics achievement were collected at pretest and posttest. Treatment and control students did not differ on mathematics assessments at pretest. Gain scores of at-risk intervention students were significantly greater than those of control peers, and the gains of at-risk treatment students were greater than the gains of peers not at risk, effectively reducing the achievement gap. Implications for Tier 2 mathematics instruction in a response to intervention (RtI) model are discussed.

This article discusses a study that experimentally evaluated the effects of supplemental instruction in reading for students in kindergarten through Grade 3. Using the Dynamic Indicators of Basic Early Literacy Skills (DIBELS) and a measure of oral reading fluency, 256 students in kindergarten through second grade (158 Hispanic, 98 non-Hispanic) were screened. Students were then randomly assigned to receive or not receive supplemental reading instruction focused on phonological awareness and decoding skills. Reading skill was assessed in the fall of the first year of participation and again in the spring of Years 1 and 2 (Times 2 and 3). Children who received the supplemental reading instruction performed significantly better on measures of word attack skills at Time 2 and on measures of word attack, word identification, oral reading fluency, vocabulary, and reading comprehension at Time 3. There were no differences in the effectiveness of instruction as a function of Hispanic students' level of English proficiency or as a function of student gender or grade.

This paper reports the effects of a two-year supplemental reading program for kindergarten through third grade students that focused on the development of decoding skills and reading fluency. Two hundred ninety-nine students were identified for participation and were randomly assigned to the supplemental instruction or to a no-treatment control group. Participants’ reading ability was assessed in the fall, before the first year of the intervention, and again in the spring of years 1, 2, 3, and 4. At the end of the two-year intervention, students who received the supplemental instruction performed significantly better than their matched controls on measures of entry level reading skills (i.e., letter-word identification and word attack), oral reading fluency, vocabulary, and comprehension. The benefits of the instruction were still clear two years after instruction had ended with students in the supplemental-instruction condition still showing significantly greater growth on the measure of oral reading fluency. Hispanic students benefited from the supplemental reading instruction in English as much as or more than non-Hispanic students. Results support the value of supplemental instruction focused on the development of word recognition skills for helping students at risk for reading failure.
