This study investigated the impact of a dynamic geometry (DG)-centered teacher professional development program on high school geometry teachers' content knowledge and their students' geometry learning. 64 geometry teachers were randomly assigned to an experimental (DG) group and a control group. Both groups received appropriate and relevant…

In 2009, Vanderbilt University's Peabody Research Institute, in coordination with the Tennessee Department of Education's Division of Curriculum and Instruction, initiated a rigorous, independent evaluation of the state's Voluntary Prekindergarten program (TN- VPK). TN-VPK is a full-day prekindergarten program for four-year-old children expected…

Dynamic Assessment (DA), is grounded in Vygotsky's idea on Sociocultural Theory (SCT) of mind, his concept of Zone of Proximal Development (ZPD) and its related metaphor; scaffolding. This study examined the effects of dynamic assessment on improving reading comprehension of Iranian intermediate students who were learning English as a foreign…

Rhythm for Reading is a programme which aims to improve children's reading ability by taking part in rhythm-based exercises such as stamping, clapping and chanting, while reading musical notation.

Purpose: The past decade has seen considerable debate about how to best evaluate the efficacy of educational improvement initiatives, and members of the educational leadership research community have entered the debate with great energy. Throughout this debate, the use of randomized experiments has been a particularly contentious subject. This…

Two intervention approaches designed to address the multifaceted academic and cognitive difficulties of low-income children who enter pre-K with very low math knowledge were tested in a randomized experiment. Blocking on classroom, children who met screening criteria were assigned to a Math + Attention condition in which the Pre-Kindergarten…

We surveyed researchers in the health and exercise sciences to explore different areas and magnitudes of bias in researchers' decision making. Participants were presented with scenarios (testing a central hypothesis with p = 0.06 or p = 0.04) in a random order and surveyed about what they would do in each scenario. Participants showed significant…

Over 200 million children under the age of 5 are not fulfilling their developmental potential due to poverty, poor health, and lack of cognitive stimulation. Experiences in early childhood have long term-effects on brain development and thus the cognitive and social-emotional skills that promote children's school success. Further, early childhood…

Each year, the Interagency Autism Coordinating Committee (IACC) releases its annual list of scientific advances that represent significant progress in the field. The 20 studies selected have given new insight into the underlying biology of autism spectrum disorder (ASD) and potential risk factors, examined the state of the science in early…

Data-based instructional programs have proliferated in American schools despite limited evidence of their effectiveness in improving educator practice and raising student achievement. We report results from a two-year school-randomized evaluation of the Achievement Network (ANet), a program providing schools with standards-aligned interim…

Community colleges nationwide are looking for solutions to help students complete developmental (remedial) math--a known barrier to graduation. Some are offering computer-assisted, modular developmental math courses that allow students to earn credits incrementally and move through the curriculum at their own pace. One of these modularized…

Looked-after children and young people (LACYP) are educationally disadvantaged compared to the general population. A systematic review was conducted of randomised controlled trials evaluating interventions aimed at LACYP aged =18 years. Restrictions were not placed on delivery setting or delivery agent.
