Mechanisms of Effect Size Differences Between Researcher Developed and Independently Developed Outcomes: A Meta-Analysis of Item-Level Data
Topics: MethodsDifferences in effect sizes between researcher developed (RD) and independently developed (ID) outcome measures are widely documented but poorly understood in education research. We conduct a meta-analysis using item-level outcome data to test potential mechanisms that explain differences in… more →
Did Mathematics Achievement Gaps for Students with Disabilities Widen after the Introduction of the Common Core and its Aligned Assessments?
This study addresses the important yet underexplored question of whether the Common Core State Standards in Mathematics, which emphasize critical thinking and problem-solving, as well as the computer-based assessments aligned with the Common Core, have facilitated or hindered learning for… more →
A Quantitative Study of Mathematical Language in Upper Elementary Classrooms
Topics: MethodsThis study provides the first large-scale quantitative exploration of mathematical language use in upper elementary U.S. classrooms. Our approach employs natural language processing techniques to describe variation in teachers’ and students’ use of mathematical language in 1,657 fourth and fifth… more →
Scaffolding Middle-School Mathematics Curricula With Large Language Models
Topics: MethodsTags: Mathematics educationDespite well-designed curriculum materials, teachers often face challenges in their implementation due to diverse classroom needs. This paper investigates whether Large Language Models (LLMs) can support middle-school math teachers by helping create high-quality curriculum scaffolds, which we… more →
STEM teacher workforce in high-need schools resilient despite shrinking supply and increasing demand
Topics: MethodsThe teacher workforce in science, technology, engineering, and math (STEM) has been a perpetual weak spot in public schools’ teaching rosters. Prior reports show the pipeline of new STEM teachers into the profession is weak while demand for instruction in STEM fields continues to grow. This… more →
The Effect of Student-Tutor Ratios: Experimental Evidence from a Pilot Online Math Tutoring Program
Topics: Student LearningTags: Tutoring, Mathematics educationBudget constraints and limited supplies of local tutors have caused many K-12 school districts to pivot from individual tutoring in-person toward small-group tutoring online to expand access to personalized instruction. We conduct a field experiment to explore the effect of increasing student-… more →
Sustained Effects of Small-Group Instruction in Mathematics
Topics: Student LearningTags: Mathematics educationRecent research suggests that using additional teachers to provide small-group instruction or tutoring substantially improves student learning. However, treatment effects on test scores can fade over time, and less is known about the lasting effects of such interventions. We leverage data from a… more →
Does Feedback on Talk Time Increase Student Engagement? Evidence from a Randomized Controlled Trial on a Math Tutoring Platform
Topics: Student LearningProviding ample opportunities for students to express their thinking is pivotal to their learning of mathematical concepts. We introduce the Talk Meter, which provides in-the-moment automated feedback on student-teacher talk ratios. We conduct a randomized controlled trial on a virtual math… more →
Early Algebra Affects Peer Composition
Topics: Student LearningAlthough existing research suggests that students benefit on a range of outcomes when they enroll in early algebra classes, policy efforts that accelerate algebra enrollment for large numbers of students often have negative effects. Explanations for this apparent contradiction often emphasize… more →
The long-term distributional impacts of a full-year interleaving math program in Nigeria
Topics: Student LearningThis study reports the findings from a year-long randomized evaluation assessing the impact of assigning 62 classrooms in Nigeria to receive either blocked or interleaved math problem sets. Blocked practice sessions focused on a single skill at a time. Interleaved problem sets alternated between… more →
Can brick phones bridge the digital learning divide? Evidence from SMS-based math practice
Topics: Student LearningHardware requirements are a barrier to widespread adoption of digital learning software among low-income populations. We investigate the demand among smallholder-farming households for a simple, adaptive math learning tool that can be accessed by widely available ``brick'' phones, and its effect… more →
Online tutoring works: Experimental evidence from a program with vulnerable children
Topics: Student LearningWe provide evidence from a randomized controlled trial on the effectiveness of a novel, 100-percent online math tutoring program, targeted at secondary school students from highly disadvantaged neighborhoods. The intensive, eight-week-long program was delivered by qualified math teachers in… more →
Ahead of the Game? Course-Taking Patterns under a Math Pathways Reform
A controversial, equity-focused mathematics reform in the San Francisco Unified School District (SFUSD) featured delaying Algebra I until ninth grade for all students. This descriptive study examines student-level longitudinal data on mathematics course-taking across successive cohorts of SFUSD… more →
When Girls Outperform Boys: The Gender Gap in High School Math Grades
Topics: Student LearningAcross an array of educational outcomes, evidence suggests that girls outperform boys on average. For example, in Chicago, ninth-grade girls earn math GPAs that are 0.29 points higher than boys on average. This paper examines explanations for this gap, such as girl-boy differences in academic… more →
The NCTE Transcripts: A Dataset of Elementary Math Classroom Transcripts
Topics: MethodsClassroom discourse is a core medium of instruction --- analyzing it can provide a window into teaching and learning as well as driving the development of new tools for improving instruction. We introduce the largest dataset of mathematics classroom transcripts available to researchers, and… more →
Stay-at-Home Peer Mothers and Gender Norms: Short-run Effects on Educational Outcomes
Topics: Families and CommunitiesIncreased exposure to gender-role information affects a girl's educational performance. Utilizing the classroom randomization in Chinese middle schools, we find that the increased presence of stay-at-home peer mothers significantly reduces a girl's performance in mathematics. This exposure also… more →
Do STEM Students Vote?
Topics: Policy, Politics, and GovernanceFor decades, pundits, politicians, college administrators, and academics have lamented the dismal rates of civic engagement among students who enroll in courses and eventually major in science, technology, engineering, and mathematics (i.e., STEM) fields. However, the research supporting this… more →
U.S. Middle School Mathematics Instruction, 2016
Topics: Student LearningIn recent decades, U.S. education leaders have advocated for more intellectually ambitious mathematics instruction in classrooms. Evidence about whether more ambitious mathematics instruction has filtered into contemporary classrooms, however, is largely anecdotal. To address this issue, we… more →
Challenges and Tradeoffs of “Good” Teaching: The Pursuit of Multiple Educational Outcomes
Topics: Teacher and Leader DevelopmentThe pursuit of multiple educational outcomes makes teaching a complex craft subject to potential conflicts and competing commitments. Using a dataset in which teachers were randomly assigned to students paired with videotapes of instruction, we both document and unpack such a tradeoff. Upper-… more →
Design and Analytic Features for Reducing Biases in Skill-Building Intervention Impact Forecasts
Topics: MethodsTags: Mathematics educationDespite policy relevance, longer-term evaluations of educational interventions are relatively rare. A common approach to this problem has been to rely on longitudinal research to determine targets for intervention by looking at the correlation between children’s early skills (e.g., preschool… more →
