Early education is replete with debates about "academic" versus "play" approaches. We evaluated 2 interventions, the "Building Blocks" (BB) mathematics curriculum and the BB synthesized with scaffolding of play to promote executive function (BBSEF), compared to a business-as-usual (BAU) control using a 3-armed cluster…

Adolescents with disabilities have great difficulty with academic content in middle school, and their teachers have difficulty teaching them to understand and use academic language. We taught teachers of 6th grade students with Learning Disabilities, over half of whom were also English Language Learners (ELL), to implement about 15 minutes of…

This experimental study examined the efficacy of a multicomponent reading intervention compared to a business-as-usual comparison condition on the reading comprehension and content area vocabulary outcomes of adolescent students with low reading comprehension. We randomly assigned 9th-grade students with low reading comprehension to a…

This randomized controlled trial examined the efficacy of an elementary school service-learning program, Connect Science (CS), on classroom practices and students' science achievement, civic engagement, and social skills. Fourth grade teachers were enrolled into intervention versus control conditions resulting in 41 classrooms (20 intervention)…

This project tested the effects of adding instruction of trios of children in patterning, mathematics, early literacy, or social studies to ongoing instruction in kindergartens. Children were randomly assigned to trios which were randomly assigned to one of four kinds of instruction. A quarter of the trios received patterning instruction with a…

Students who drop out of their science, technology, engineering, and math (STEM) majors commonly report that they lack skills critical to STEM learning and career pursuits. Many training programs exist to develop students' learning skills and they typically achieve small to medium effects on behaviors and performance. However, these programs…

Despite widespread efforts to address barriers to college success, low-income and first-generation students continue to complete college at substantially lower rates that their more advantaged peers. A review of causal research to date has linked comprehensive interventions (e.g. programs that provide students with a combination of financial,…

Children from low-income families are at greater risk for poor social-emotional development and physical health and may be in need of intervention. This study examined the extent to which the "Positive Action" ("PA") preschool lessons improved low-income children's social-emotional competence and health behaviors. Mixed…

Students with writing difficulties may have difficulty when writing informational text with source material due to (a) inexperience with such text and (b) difficulties reading and understanding source material. Teaching students to take notes related to informational text using text structures (e.g., description, compare/contrast) may help them…

This study tests the influence of a video-based, analysis-of-practice professional development (PD) program on upper-elementary teachers' science content knowledge, pedagogical content knowledge, and teaching practice and on their students' achievement. Using a cluster-randomized experimental design, the study compares the outcomes for teachers in…

This study evaluated the efficacy of the Word Learning Strategies (WLS) supplementary program designed to develop upper-elementary students' vocabulary skills in order to improve reading comprehension. The study used a true, group-randomized, experimental design, which randomly assigned 46 4th grade classrooms (n=1324 students) from 12 districts…

Interactive book reading (IBR) has proven effective for increasing children's lexicons with most of the results based on students' learning of nouns. Little is known about the application of IBR to instructional verbs (i.e., words used during the instruction of academic content). To address this gap, 122 prekindergarten children were recruited…

Observation and performance feedback to support traditional training methods are central tools for preservice practitioner preparation and in-service practitioner professional development. Research highlights how some specific characteristics of feedback (e.g., the latency between behavior and feedback) can impact the effectiveness. One method of…

The purpose of this study was to explore the efficacy of fractions intervention with and without an embedded self-regulation (SR) component for third-grade students at risk for mathematics disabilities. Fractions intervention focused on magnitude understanding and word problems. Embedded SR was designed to support a growth mindset (fostering…

"U-Pace" instruction, comprised of concept mastery and amplified assistance, has shown promise in increasing undergraduate success. To evaluate the efficacy of "U-Pace" instruction for students at risk for college noncompletion and students not at risk and to determine whether concept mastery, amplified assistance, or both…
