The purpose of this technical appendix is to share more detailed results and to describe more fully the sample and methods used in the research included in the brief, "The Widening Achievement Divide during COVID-19." The authors investigated two main research questions in this brief: (1) To what degree have students' reading and math…

The current exploratory study used data on students in grades six through 12 in North Carolina to examine the effectiveness of their mathematics teachers. Its purpose was fourfold: (1) to identify teacher qualification indicators that are most important for predicting students' math scores; (2) to empirically identify teacher qualification…

This quantitative study examined the proportions of students enrolling in and completing transfer-level math pre- and post-Assembly Bill 705 (AB 705), as well as different predictors affecting the completion of transfer-level math within the first year. The study drew attention to the relationship between students' race/ethnicity and the…

Background/Context: Early childhood education research has consistently found evidence of immediate, positive effects on developmental outcomes. Despite these strong initial benefits, follow-up analyses often reveal that these effects fadeout in the years following participation (e.g., Bailey et al., 2017, Clements et al., 2013; Lipsey et al.…

Background: Malawi's primary education system made progress in increasing access to school over the last decade, but is challenged to provide quality learning in the face of expanding enrollment (World Bank 2021). By Standard 4, 19 percent of students still score zero on Standard 1 math items and only 22 percent are able to comprehend a short…

National mathematics achievement results show that elementary students in the United States are not increasing in cognitive ability or critical thinking skills (NAEP, 2020). For this increase, mathematically promising students require more opportunities for cognitively demanding mathematics instruction. As a result, this descriptive study focused…

We examined the additive associations of two motivational beliefs (growth mindset and academic self-efficacy) and self-regulation with mathematics and English Language Arts (ELA) scores, as well as the interplay of students' beliefs and self-regulation skills, controlling for previous test scores. We tested whether these pathways differed across…

We evaluate the effects of grade retention on students' academic, attendance, and disciplinary outcomes in Indiana. Using a regression discontinuity design, we show that third grade retention increases achievement in English Language Arts (ELA) and math immediately and substantially, and the effects persist into middle school. We find no evidence…

Bandura's influential theory has been used to argue that teachers with high self-efficacy will be more effective at increasing pupil achievement--and a voluminous empirical literature has repeatedly documented associations consistent with this claim. However, few studies have considered whether these correlations reflect an underlying causal…

We examine whether and how teachers' major fields in college affect students' achievement, exploiting within-student variation across subfields in natural science (i.e. physics, chemistry, biology, and Earth science). Using middle-school students' data from the TIMSS and controlling for student-teacher fixed effects, we find that teachers improve…

Using a case study approach, we explored the science and math classroom experiences of urban high school students. Our purposeful sample included 11 high-achieving students (mostly minoritized students) who graduated from the same school and participated in an out-of-school science and medicine/health program. Using 35 semistructured interviews…

The purpose of this evaluation was to examine the impact of i-Ready Personalized Instruction on math achievement, as measured by SBA scores. We compared "striving learner" students who were assigned to use i-Ready Personalized Instruction (Treatment students) and "striving learner" students assigned to only receive i-Ready…

Inequities have existed in formal public education since its inception in the United States. The educational experiences and outcomes for Black students have historically lagged behind their non-Hispanic, and White peers. This dissertation uses data from The Early Childhood Longitudinal Survey for the Kindergarten Class of 2011 (ECLS-K: 2011) to…

In 2010, Teach For America (TFA) launched a major expansion effort, funded in part by a five-year Investing in Innovation scale-up grant from the U.S. Department of Education. To examine the effectiveness of TFA elementary school teachers in the second year of the scale-up, we recruited thirty-six schools from ten states and randomly assigned…

This study examined the effect of implementing personal devices into a fifth-grade mathematics classroom. Thirty-eight fifth graders participated in this eight-week project with a focus on six students to track their growth. During this study, students engaged in technology-based stations that pertained to our geometry unit and coordinate unit.…
