In this quasi-experimental pretest-posttest study we examined the effects of differentiated instruction (DI) in within-class ability groupings of 246 Montenegrin fourth-graders and their ability to solve algebraic equations. We assessed 2 parallel student groups at equal achievement levels to compare DI, in which teaching and work modes were…

This implementation project focused on supporting teachers who provide mathematics instruction and/or intervention to students with mathematics learning disabilities (MLD) and mathematics difficulties (MD). The research team worked with three schools, over three years. Instructional delivery differed across schools, primarily in setting and amount…

The potential of tasks to foster mathematical learning and understanding is an important aspect of instruction and their implementation in teaching is thus often viewed to be positively related to the quality of instruction. Both the selection of tasks as well as their implementation in the classroom depend on many factors, with teachers'…

The "Coding Our Future" intervention aimed to develop and implement a Computer Science (CS) curriculum, and to train teachers to offer computer science courses in elementary and middle schools. Its goals were to enhance students' competency and self-efficacy in computer science and to boost the enrollment of underrepresented students in…

The Innovative STEM--Computer Science and Engineering Design (STEM CSED) project (Award #: U411C190169), funded by an Early-Phase Education Innovation and Research (EIR) grant, sought to strengthen math achievement and foster positive attitudes toward STEM and computer science among students in Waukegan Community Unit School District #60, a large,…

We explored the challenges, limitations, and potential effectiveness of a large-scale computerized working memory and numeracy intervention in the classroom with children at risk of mathematical learning disabilities (n = 428, M[subscript age] = 83.85 months, 41% female). Children were assigned to four different treatment protocols (working memory…

This multi-method study evaluated the alignment of the Eureka Math Pre-K-5 curriculum with the district's RFP 4478.1, its effectiveness for students and teachers, and the fidelity of lesson implementation in Pre-K-5 classrooms. Data from staff surveys, student performance, and classroom observations were analyzed. Staff generally agreed that the…

This study evaluates the first year of implementation of "How Are the Children" (HATC), a project-based social-emotional learning (SEL) curriculum designed to enhance high school student's social-emotional (SE) development. Through documentary filmmaking and lessons based on SE competencies, HATC aims to provide SEL support that…

In December 2022, Rock Island-Milan School District #41 (RIMSD), in partnership with the Connect with Kids Network (CWK) and Empirical Education, received an early-phase Education Innovation and Research (EIR) grant from the U.S. Department of Education. RIMSD contracted with Empirical Education to conduct a one-year teacher-level randomized…

Principals are the second-largest school-based contributor to K-12 students' academic progress. However, there is little research evaluating whether efforts to develop principals' skills improve school effectiveness. We conducted randomized controlled trial studies of the impacts of a professional development program called the Executive…

In this qualitative case study, we investigated the role of an advanced math curriculum with language scaffolding on the development of geometric and visual-spatial reasoning skills in young mathematically promising English learners (MPELs). Specifically, we examined the effects of providing MPELs with challenging and supportive math curriculum to…

Existing literature on the impact of Common Core State Standards in Math has shown little benefit, but has not examined variation in outcomes based on implementation strategies, student subgroups, or outcomes other than test scores. We use a difference-in-differences approach with school fixed effects to compare outcomes in pre- and post-standards…

This research evaluated the implementation of a climate science curriculum intervention for students in Grades 4 and 5, including those who were typically achieving and those with difficulties in mathematics, reading, or both. Pre- and posttests of measurement and climate change science concepts were administered at the beginning and end of each…

This study investigates the effect of E-learning (EL), blended learning (BL) and flipped learning (FL) approaches on the mathematics achievement, self-regulation and mathematics self-efficacy. Participants consist of 163 first-year students attending an associate degree program (a 2-year program) of a state university. The EL, BL and FL settings…

Mathematics requirements are a significant barrier to completing a college credential for many college students. In an effort to change the tide, colleges across the country are working to implement mathematics pathways, which encourages all students to enroll in one of several college-level mathematics courses that best aligns with their chosen…
