Early literacy is a key developmental milestone for succeeding in school, yet far too many children in America, particularly the most socially vulnerable, are not meeting this key milestone. For example, NAEP data from 2013 shows that over 80% of Black and Latinx students are below proficient in reading by the end of fourth grade, as compared to…

This paper develops models to measure growth in student achievement with a focus on the possibility of differential growth in achievement for low and high-achieving students. We consider a gap-closing model that evaluates the degree to which students in a target group -- students in the bottom quartile of measured achievement -- perform better…

Improving achievement in Science, Technology, Engineering, and Mathematics (STEM) is essential for elevating individual success and solving societal challenges. Yet national and international assessments paint a poor picture of students' STEM competencies (NAEP, 2019; OECD, 2018). An untapped avenue to improve STEM education lies in developing…

Background/Context: Increasing evidence suggests a connection between racial differences in rates of exclusionary discipline (suspensions/expulsions) and academic achievement by (Losen & Martinez, 2020; Reardon et al., 2018). Black students receive out-of-school suspensions and expulsions at disproportionately higher rates, which is associated…

Inequality in the shadow? Cross-national comparisons of the effects of additional instruction on math and science performance based on PISA 2018 data Background Many educational systems worldwide are experiencing a growing demand for shadow education, which often takes the form of outside-school educational activities such as private tutoring…

Background/Context: As part of a national movement to eliminate a global tracking system that disproportionately assigned underserved students to low-level math classes, the Chicago Public Schools (CPS) mandated academic algebra for all students entering high school in 1997. The results were disappointing: low-skill students experienced elevated…

Background: In the immediate aftermath of school closures related to COVID-19, efforts to unpack the impact of the pandemic on student outcomes surged. As schools have returned to fully in-person learning, that focus has shifted towards the implementation and evaluation of interventions to remediate or accelerate impacted learning. However,…

Background/Context: Literacy stands as a pivotal life skill, especially as it strengthens education across subjects. The elementary years are crucial for mastering literacy, yet national assessments show a decline in elementary students' reading proficiency, with only 33% of American fourth graders reading at grade level (National Center for…

Background: Race to the Top era teacher evaluation reforms sought to improve teacher effectiveness and, ultimately, student achievement through either accountability or developmental mechanisms (Donaldson, 2021). Quasi-experimental teacher evaluation studies find mixed results in urban and large-scale settings (Dee & Wyckoff, 2015; Steinberg…

Background: Research has shown that teacher feedback is critical for student learning and well-being (Siegle & McCoach, 2007; Wisniewski et al., 2020). However, teachers often provide more positive feedback to students from high socioeconomic backgrounds than to those from low socioeconomic backgrounds (Rimm-Kaufman et al., 2000; Tobisch &…

Background: Pre-k convergence refers to the tendency for the positive effects of pre-k on children's academic skills to diminish over time, observed across decades of observational and experimental studies (Ansari et al., 2020). Researchers have tested multiple mechanisms to explain convergence, with mixed results; none of the proposed mechanisms…

Background: Over the last twenty years, retention has increased in popularity with policymakers who are concerned with student achievement and aim to end social promotion (i.e., the practice of advancing a student to the next grade level although they have not yet met the academic expectations of their current grade level). Despite calls to expand…

The negative impact of COVID-19 on students persists three years after the onset of the pandemic. A substantial body of research shows that students have yet to recover to their learning trends before the pandemic (Callen et al. 2023, Lewis & Kuhfeld 2023, Cohodes et al., 2022). This suggests that students face a lengthy road to recovery, and…

Background: Observation Studies, Unmeasured Confounding, and Sensitivity Analysis: An important part of educational research is identifying important, potentially causal, factors that influence children's learning from observational studies. However, it is well-known that discovering such factors from observational studies can be biased due to…

Background: Evidence of educational improvement is essential for ensuring that we are providing students with meaningful and optimal learning experiences. But what counts as equitable evidence of educational improvement? Our presentation will discuss one organization's attempt to create an environment in which evidence is contextualized in ways…
