Rogde, Kristin; Melby-Lervåg, Monica; Lervåg, Arne – Journal of Research on Educational Effectiveness, 2016
Second-language learners display poorer general language skills in the language used at school than their monolingual peers, which is a concern because general language skills (vocabulary, grammar, language expression, and comprehension) provide the foundation for later academic success. In a randomized controlled trial, we examined the efficacy…

Cowan, James; Goldhaber, Dan – Journal of Research on Educational Effectiveness, 2016
We study the effectiveness of teachers certified by the National Board for Professional Teaching Standards (NBPTS) in Washington State, which has one of the largest populations of National Board-Certified Teachers (NBCTs) in the nation. Based on value-added models in math and reading, we find that NBPTS-certified teachers are about 0.01-0.05…

Goldhaber, Dan; Chaplin, Duncan Dunbar – Journal of Research on Educational Effectiveness, 2015
In an influential paper, Jesse Rothstein (2010) shows that standard value-added models (VAMs) suggest implausible and large future teacher effects on past student achievement. This is the basis of a falsification test that "appears" to indicate bias in typical VAM estimates of teacher contributions to student learning on standardized…

Zamarro, Gema; Engberg, John; Saavedra, Juan Esteban; Steele, Jennifer – Journal of Research on Educational Effectiveness, 2015
This article investigates the use of teacher value-added estimates to assess the distribution of effective teaching across students of varying socioeconomic disadvantage in the presence of classroom composition effects. We examine, via simulations, how accurately commonly used teacher value-added estimators recover the rank correlation between…

Isenberg, Eric; Teh, Bing-ru; Walsh, Elias – Journal of Research on Educational Effectiveness, 2015
Researchers often presume that it is better to use administrative data from grades 4 and 5 than data from grades 6 through 8 for conducting research on teacher effectiveness that uses value-added models because (1) elementary school teachers teach all subjects to their students in self-contained classrooms and (2) classrooms are more homogenous at…

Isenberg, Eric; Walsh, Elias – Journal of Research on Educational Effectiveness, 2015
We outline the options available to policymakers for addressing co-teaching in a value-added model. Building on earlier work, we propose an improvement to a method of accounting for co-teaching that treats co-teachers as teams, with each teacher receiving equal credit for co-taught students. Hock and Isenberg (2012) described a method known as the…

Parsons, Eric; Koedel, Cory; Podgursky, Michael; Ehlert, Mark; Xiang, P. Brett – Journal of Research on Educational Effectiveness, 2015
There is increased policy interest in extending test-based evaluations in K-12 education to include student achievement in high school. High school achievement is typically measured by performance on end-of-course exams (EOCs), which test course-specific standards in a variety of subjects. However, unlike standardized tests in the early grades,…

Johnson, Matthew T.; Lipscomb, Stephen; Gill, Brian – Journal of Research on Educational Effectiveness, 2015
Teacher value-added models (VAMs) must isolate teachers' contributions to student achievement to be valid. Well-known VAMs use different specifications, however, leaving policymakers with little clear guidance for constructing a valid model. We examine the sensitivity of teacher value-added estimates under different models based on whether they…

Weiss, Michael J.; Mayer, Alexander K.; Cullinan, Dan; Ratledge, Alyssa; Sommo, Colleen; Diamond, John – Journal of Research on Educational Effectiveness, 2015
Community colleges play a vital role in higher education, enrolling more than one in every three postsecondary students. While their market share has grown over the past 50 years, students' success rates remain low. Consequently, community college stakeholders are searching with mounting urgency for strategies that increase rates of success. We…

Vadasy, Patricia F.; Sanders, Elizabeth A.; Nelson, J. Ron – Journal of Research on Educational Effectiveness, 2015
A two-cohort cluster-randomized trial was conducted to estimate effects of small-group supplemental vocabulary instruction for at-risk kindergarten English learners (ELs). Connections students received explicit instruction in high-frequency decodable root words, and interactive book reading (IBR) students were taught the same words in a storybook…

Caro, Daniel H. – Journal of Research on Educational Effectiveness, 2015
This paper applies the causal mediation framework proposed by Kosuke Imai and colleagues (Imai, Keele, & Tingley, 2010) to educational research by examining the causal mediating role of early literacy activities in parental education influences on reading performance. The paper argues that the study of causal mediation is particularly relevant…

Springer, Matthew G.; Rosenquist, Brooks A.; Swain, Walker A. – Journal of Research on Educational Effectiveness, 2015
In recent years, the largely punitive accountability measures imposed by the 2001 No Child Left Behind Act have given way to an emphasis on financial incentives. Although most policy interventions have focused primarily on linking teacher compensation to student test scores, several recent studies have examined the prospects for the use of…

Scammacca, Nancy K.; Fall, Anna-Mária; Roberts, Greg – Journal of Research on Educational Effectiveness, 2015
Effect sizes are commonly reported for the results of educational interventions. However, researchers struggle with interpreting their magnitude in a way that transcends generic guidelines. Effect sizes can be interpreted in a meaningful context by benchmarking them against typical growth for students in the normative distribution. Such benchmarks…

Clarke, Ben; Baker, Scott; Smolkowski, Keith; Doabler, Christian; Strand Cary, Mari; Fien, Hank – Journal of Research on Educational Effectiveness, 2015
This study examined the efficacy of a core kindergarten mathematics program, Early Learning in Mathematics (ELM), a 120-lesson program with four content strands: (a) number operations, (b) geometry, (c) measurement, and (d) vocabulary. The study utilized a randomized block design, with 129 classrooms randomly assigned within schools to treatment…

Jackson, Jacob S. – Journal of Research on Educational Effectiveness, 2015
States are currently seeking ways to improve alignment between K-12 and postsecondary education and better prepare students for postsecondary schooling. Some states have begun implementing policies that inform high school students that they are not ready for college-level courses well before they graduate, in order to give both notice and time to…
