The goal of the current study is to examine the degree to which measures of quality of implementation and student engagement moderate pretest--posttest changes in mediating variables that are targeted by DARE "keepin' it REAL." DARE officers (10 elementary school, five middle school) taught DARE "keepin' it REAL lessons to 1,017…

The purpose of this evaluation was to examine the impact of i-Ready Personalized Instruction that met Curriculum Associates' recommended usage levels on mathematics achievement, as measured by the Massachusetts Comprehensive Assessment System (MCAS) mathematics assessment. This study compared mathematics achievement growth of students who used…

The purpose of this evaluation was to examine the impact of i-Ready Personalized Instruction that met Curriculum Associates' recommended usage levels on ELA achievement, as measured by the Massachusetts Comprehensive Assessment System (MCAS) ELA assessment. This study compared the ELA achievement growth in the 2020-21 school year of students who…

Data from a large-scale math intervention program were used to evaluate the degree to which implementation fidelity (IF) and interventionist content knowledge were associated with student outcomes. Data were available for 33 interventionists serving 658 students in Grades 4-6 across one school year. A series of multilevel models were fit to the…

This study addresses the effectiveness of a nationally used core reading program that reflects the research-based practices recommended by the National Reading Panel. This and other similar programs are increasingly used to prevent reading difficulties and ensure that all children are reading at or above grade level by the end of third grade. The…

This study examined the hypothesis that assisted writing during reading improves reading comprehension. The hypothesis was derived from sociocognitive and constructivist theory and research and implemented in the form of a curricular intervention called Writing Intensive Reading Comprehension after its main feature of bringing together reading…

These appendices accompany the report "Final Report of the i3 Impact Study of Making Sense of SCIENCE, 2016-17 through 2017-18." Science education has experienced a significant transition over the last decade, catalyzed by a re-envisioning of what students should know and be able to do in science. That re-envisioning culminated in the…

This study evaluated the efficacy of Accelerated Reader, a computer-based learning program, at improving student reading. Accelerated Reader is a progress-monitoring, assessment, and practice tool that supports classroom instruction and guides independent reading. Researchers used a randomized controlled trial to evaluate the program with 344…

The purpose of this study was to examine the effects of Mentoring Mathematical Minds (M3) units on gains in mathematics achievement and English proficiency of mathematically promising English language learners (MPELLs) in the third grade. The M3 program, developed by Gavin et al., was implemented for 1 year with treatment MPELLs (n = 86) but not…

First Step to Success (First Step; Walker et al., 1997, 1998) is a secondary-level intervention for students with behavior problems in early elementary school. The purposes of this study were to assess whether effects in student behavior and academics at posttest shown in a recent efficacy trial (Walker et al., 2009) were maintained at follow-up…
