Many seem to believe that researcher-made tests are unnecessary, if not inappropriate, for evaluating reading comprehension interventions. We suggest that this view reflects a zeitgeist in which researcher-made (proximal) tests that align with the researchers' interventions are closely scrutinized and often devalued, whereas commercially developed…

To estimate the long-term effects of the Reading Recovery® intervention, a regression discontinuity design (RD) was implemented in a randomly selected sample of Reading Recovery schools during each year of the federally-funded i3 Scale-Up external evaluation (2011-2015) and also in one additional cohort during the 2016-2017 school year. Long-term…

Young students at risk for reading difficulties are likely to have long-term reading difficulties if they are not provided with evidence-based, supplemental instruction. This pilot study evaluated the feasibility of a Tier 2 reading intervention ("Reading RULES! Kindergarten"; RRK) and its promise to improve outcomes for kindergarten…

Although research provides ample evidence of teaching methods that facilitate students' learning of specific word meanings, the potential of instruction to impact students' general vocabulary knowledge has remained an unanswered question. This article reports on a three-year formative experiment that developed, implemented, and tested a long-term,…

Despite widespread enthusiasm for remedial education programming with refugee populations, there is little rigorous evidence on how to design and implement such programs. We employ a cluster-randomized design of non-equivalent treatment groups to test the impact of access to two types of program enhancement: longer program duration and the…

Multilingualism in education is encouraged in South Africa, and children are expected to become bilingual and biliterate during the early primary grades. Much focus has been placed on measuring literacy in children's first language, often the medium of instruction (MOI), and English, the language typically used as MOI from fourth grade. However,…

Reading and writing are critical to students' success in and outside of school. Because they draw on common sources of knowledge and cognitive processes, involve meaning making, and can be used conjointly to accomplish important learning goals, it is often recommended that reading and writing should be taught together. This meta-analysis tested…

Background: Most funders require non-governmental organisations to evaluate the effectiveness of their programmes. However, in our experience, funders seldom fund evaluation endeavours and organisational staff often lack evaluation skills. Aim: In this outcome evaluation of Living through Learning's (LTL) class-based English-medium Coronation…

We conducted a 14-week experimental study of 2 versions of a relatively comprehensive RC intervention that involved 50 classroom teachers, 15 tutors, and 116 children drawn in equal proportions from grades 3 and 5 in 13 schools in a large urban school district. Students were randomly assigned in equal numbers to the two tutoring conditions and a…

This study assesses the long-term linguistic and academic outcomes associated with different bilingual language education models for low-income dual language learners (DLLs) residing in a bilingual, bicultural context. As part of the Miami School Readiness Project (MSRP), we analyzed the impact of program model on gains in English language…

This ex-post-facto quasi-experimental research design was conducted by selecting a convenient sample of approximately 2,000 3rd grade ELLs who took the regular reading and math English STAAR test during the 2014-15 school year in an urban southern Texas school district. This study was conducted using a quantitative research method of data…

We investigate the impact of a relatively brief cross-curricular intervention, Word Generation, on middle school students' development of taught academic vocabulary. Students (n = 8382) in forty-four middle schools in three urban districts were randomly assigned to treatment or control conditions. Treatment teachers implemented the program with…

We present the results of a study of local education agency (LEA)-based interventions to improve the reading outcomes of struggling readers in sixth grade. The sample included 1,076 intervention students and 3,644 comparison students. Regression discontinuity was used to evaluate intervention impact. The study contributes to the field by…

In critiquing our paper on "The literacy performance of ex-Reading Recovery students between two and four years following participation in the program: Is this intervention effective for students with early reading difficulties?", Schwartz argues that we have engaged in pursuing political and ideological agendas as part of our ongoing…
