Several school districts in Georgia use two teacher-administered diagnostic assessments of student knowledge of mathematics as part of their multi-tiered system of support in grades K-8: the Global Strategy Stage (GloSS; New Zealand Ministry of Education, 2012) and the Individual Knowledge Assessment of Number (IKAN; New Zealand Ministry of…

This meta-analysis systematically reviewed the most up-to-date literature to determine the effectiveness of reading interventions on measures of word and pseudoword reading, reading comprehension, and passage fluency, and to determine the role intervention and study variables play in moderating the impacts for students at risk for reading…

The purpose of this brief is to present an overall picture of how well early reading interventions are working for students in Grades 1-3. Using a meta-analytic approach, this paper combines findings from several studies to determine the effectiveness of early reading interventions for students who are struggling with learning to read.

The purpose of this efficacy study was to examine the impact of the Teacher Study Group (TSG) professional development program in vocabulary, on teacher knowledge, observed teaching practice, and student vocabulary achievement, when implemented with first grade teachers in Title 1 schools. This multi-site cluster randomized trial was implemented…

Response to intervention (RTI) is a comprehensive early detection and prevention strategy used to identify and support struggling students before they fall behind. An RTI model usually has three tiers or levels of support. Tier 1 is generally defined as classroom instruction provided to all students, tier 2 is typically a preventive intervention…

This article reviews published experimental studies from 2000 to 2012 that evaluated the effects of providing reading interventions to English learners who were at risk for experiencing academic difficulties, including students with learning disabilities. Criteria included: (a) the study was published in a peer-referred journal, (b) the study was…

Replication studies are extremely rare in education. This randomized controlled trial (RCT) is a scale-up replication of Fuchs et al., which in a sample of 139 found a statistically significant positive impact for Number Rockets, a small-group intervention for at-risk first graders that focused on building understanding of number operations. The…

Since 2007, when this technical report was originally issued, the assessment field has made considerable progress in developing valid and reliable screening measures for early mathematics difficulties. This update includes new research published since 2007. It focuses on valid and reliable screening measures for students in kindergarten and first…

Randomized field trials were used to examine the impact of the Teacher Study Group (TSG), a professional development model, on first grade teachers' reading comprehension and vocabulary instruction, their knowledge of these areas, and the comprehension and vocabulary achievement of their students. The multisite study was conducted in three large…

Randomized field trials were used to examine the impact of the Teacher Study Group, a professional development model, on first grade teachers' reading comprehension and vocabulary instruction, their knowledge of these areas, and on the corollary comprehension and vocabulary achievement of their students. The multi-site study was conducted during…

The purpose of this study was to determine the effects of an early numeracy preventative Tier 2 intervention on the mathematics performance of first-grade students with mathematics difficulties. Researchers used a pretest-posttest control group design with randomized assignment of 139 students to the Tier 2 treatment condition and 65 students to…

This study sought to examine the effects of Tier 2 intervention in a multitiered model on the performance of first- and second-grade students who were identified as having mathematics difficulties. A regression discontinuity design was utilized. Participants included 126 (Tier 2, n = 26) first graders and 140 (Tier 2, n = 25) second graders. Tier…
