This article reviews research on the achievement outcomes of elementary mathematics programs. 85 rigorous experimental studies evaluated 64 programs in grades K-5. Programs were organized in 6 categories. Particularly positive outcomes were found for tutoring programs. Positive outcomes were seen in studies focused on professional development for…

Zambia faces many challenges common to low- and middle-income countries as it seeks to improve its education system, including low literacy rates for young Zambians and low public expenditure on education. In the past 20 years, Zambia's school system has expanded to reach more children in rural areas, primarily through community schools, which are…

The Massachusetts Department of Elementary and Secondary Education (DESE), like other state education agencies, recognizes that a key lever to turning around low-performing schools is the quality of instruction and thus embeds a schoolwide instructional quality measure into its monitoring process. Massachusetts' schoolwide quality instruction…

This paper reports math and reading academic achievement and growth in grades 2 to 8 for Hispanic participants and nonparticipants of a Spanish-English dual language program. I apply a piecewise multilevel growth model to administrative data from a large school district that enrolls a substantial English Learner student population. Dual language…

This randomized controlled trial examined effects of the MyTeachingPartner-Math/Science intervention on the quality and quantity of teachers' mathematics and science instruction, and children's mathematics and science outcomes in 140 pre-kindergarten classrooms. Teachers participated in the intervention for two years with consecutive cohorts of…

Georgia's Pre-K Longitudinal Study followed a statewide sample of 1,169 children who attended Georgia's Pre-K Program in 2013-14 through their 4th grade year in 2018-19. The study was conducted by researchers at the Frank Porter Graham (FPG) Child Development Institute at the University of North Carolina at Chapel Hill. The following summary…

Children start preschool with large individual differences in their early numerical abilities. Little is known about the importance of heterogeneous patterns that exist within these individual differences. A person-centered analytic approach might be helpful to unravel these patterns and the cognitive and environmental factors that are associated…

Causal search algorithms have been effectively applied in different fields including biology, genetics, climate science, medicine, and neuroscience. However, there have been scant applications of these methods in social and behavioral sciences. This article provides an illustrative example of how causal search algorithms can shed light on…

We used time-varying effect modelling of two very large samples of fourth-grade students (N[subscript reading] = 148,240, N[subscript mathematics] = 152,220) to investigate associations between adoption and over-time implementation of a de facto cap on special education service receipt and over-time likelihoods of disability identification from…

The pursuit of multiple educational outcomes makes teaching a complex craft subject to potential conflicts and competing commitments. Using a data set in which teachers were randomly assigned to classes paired with videotaped lessons, we both document and unpack such a tradeoff. Upper-elementary teachers who excel at raising students' math test…

The purpose of this study was to assess the effectiveness of explicit instruction, compared to constructivist instruction, in teaching subtraction in schools with a high concentration of students from a disadvantaged social background: eighty-seven second graders (mean age in months = 90.95, SD = 5.30). Two groups received explicit versus…

The purpose of this study was to conduct a direct replication of the study of Bressoux and Bianco of 2004 regarding long-term effects of teachers in primary education on language and mathematics achievement of students. They found a short-term effect of the teacher in the same grade, but they did not find a long-term effect of the teacher of the…

The investigation attempted to find out the competence evidence among the grade 9 mathematics teachers in the secondary schools of Dumaguete City, Philippines. Survey and correlational methods of research were employed with the aid of questionnaire-checklist to profile the teachers' number of years in teaching Mathematics, training and seminars…

In this paper, we tell a story of iterative design and continual improvement of an asynchronous technological resource, pencasts, to support development of students' modeling skills while studying at home. Our students were typically engineering majors, enrolled in differential equations as a prerequisite for their subsequent engineering courses.…

Radical subject acceleration, or moving students through a subject area faster than is typical, including skipping grades, is a widely accepted approach to support students who are gifted and talented. This is done in order to match the student's cognitive level and learning needs. This case study explored radical subject acceleration for gifted…
