Women and minorities remain underrepresented in chemistry bachelor's degree attainment in the United States, despite efforts to improve their early chemistry achievement through supplemental academic programs and active-learning approaches. We propose an additional strategy for addressing these disparities: course-based, social-psychological…

The purpose of this study is to evaluate the Advancement Via Individual Determination (AVID) program and to derive estimates of program costs. We used the Coarsened Exact Matching approach to match AVID students with non-AVID students on 40 baseline characteristics. After matching, we estimated group differences in high-school graduation and…

I conduct a statewide experiment in Michigan with nearly 50,000 high-achieving high school seniors. Treated students are mailed a letter encouraging them to consider college and providing them with the web address of a college information website. I find that very high-achieving, low-income students, and very high-achieving, minority students are…

Most U.S. classrooms serve students with various linguistic and academic needs. Tier-I universal approaches support English language learners (ELLs) without segregating them into a different track and thereby constraining future learning opportunities. The current study examines whether Word Generation (WG), a Tier-I discussion-based program…

A classroom randomized efficacy trial conducted over four years in 7 community-based preschool and 6 Head Start programs investigated effects of the Second Step Early Learning (SSEL) curriculum on end of preschool executive functioning (EF) and social-emotional (SE) skills in low-income children. Outcomes are reported for n=770 four-year-olds…

Many college students abandon their goal of completing a degree in science, technology, engineering, or math (STEM) when confronted with challenging introductory-level science courses. In the U.S., this trend is more pronounced for underrepresented minority (URM) and first-generation (FG) students, and contributes to persisting racial and…

Learning communities are a high impact activity that can influence students' likelihood for success. Colorado State University (CSU) created the Key Communities (Key) program, which is open to all students but targets students that have persistently lower graduation and retention rates. The majority of Key students are under-represented…

There are many approaches to solving the problem of underrepresentation of some racial and ethnic groups and women in scientific and technical disciplines. Here, the authors evaluate the association of a summer bridge program with the graduation rate of underrepresented minority (URM) students at a selective technical university. They demonstrate…

A theoretical analysis of the development of numerical representations indicated that playing linear number board games should enhance preschoolers' numerical knowledge and ability to acquire new numerical knowledge. The effect on knowledge of numerical magnitudes was predicted to be larger when the game was played with a linear board than with a…

This study examines the impact of "Disaggregate Instruction" on students' science learning. "Disaggregate Instruction" is the idea that science teaching and learning can be separated into conceptual and discursive components. Using randomly assigned experimental and control groups, 49 fifth-grade students received web-based…

In this article, we report kindergarten student and teacher outcomes from a quasi-experimental evaluation of The Superkids, a systematic, phonics-based, comprehensive K-2 reading program. We recruited 23 kindergarten teachers to implement The Superkids program from a diverse, yet predominantly ethnic minority, group of classrooms from across the…

Our research project was guided by the assumption that students who learn to understand phenomena in everyday terms prior to being taught scientific language will develop improved understanding of new concepts. We used web-based software to teach students using a "content-first" approach that allowed students to transition from…

In this article, the authors report achievement outcomes of a multisite cluster randomized field trial of Open Court Reading 2005 (OCR), a K-6 literacy curriculum published by SRA/McGraw-Hill. The participants are 49 first-grade through fifth-grade classrooms from predominantly minority and poor contexts across the nation. Blocking by grade level…

This article describes EXCEL, a program that encourages youth underrepresented in higher education to enroll in higher education, specifically at the sponsoring university. Eighty-three eighth grade students with GPA of B and above and standardized test scores at grade level or above were randomly assigned to the program or to a control group. The…

The Reading Rescue tutoring intervention model was investigated with 64 low-socioeconomic status, language-minority first graders with reading difficulties. School staff provided tutoring in phonological awareness, systematic phonics, vocabulary, fluency, and reading comprehension. Tutored students made significantly greater gains reading words…
