Teachers' knowledge plays a central role in technology integration. In this study we analyze situations, where there is some divergence between the mathematical results and the information offered by the graphing calculator (lack of mathematical fidelity), putting the focus in the teachers and in their approaches. The goal of this study is to…

Powerful learning environments (PLEs) are based on a social constructivist theory of learning, providing a stimulating, resource-rich and inquiry-supportive environment for student self-regulated learning. Fidelity of implementation (FOI) for such PLEs is dependent on several factors, the most critical factor being the teacher's belief system,…

This study investigated the effect a computer intervention program has on student proficiency in the Algebra 1 End of Course (EOC) examination. This study utilized the intervention math program IXL Math, a computerized program that targets individual students' skill practice and supports students' need to accelerate mastery of Algebra 1 skills in…

Background: Schools increasingly prioritize social-emotional competence and bullying and cyberbullying prevention, so the development of novel, low-cost, and high-yield programs addressing these topics is important. Further, rigorous assessment of interventions prior to widespread dissemination is crucial. Objective: This study assesses the…

Purpose: The purpose of the study was to evaluate the implementation and impact of the IDEA Public Schools' Mathematics Curriculum Redesign (MCR) effort, funded by an Innovation and Research (EIR) grant. Methods: The study used a quasi-experimental matching design to examine the effect of MCR on student achievement outcomes. The study compared…

The purpose of this study is to evaluate the implementation and impacts of the Building Assets, Reducing Risks (BARR) model in its first year of implementation in 66 schools across the U.S. and to document scale-up progress during the Investing in Innovation (i3) grant period (2017-2021). The impact evaluation included 21,529 9th grade students…

Despite its promise to help teachers meet the needs of diverse learners, district usage of Achieve3000® among most students with access to it remains far below the optimal level necessary for them to realize literacy growth and college and career readiness. Only a tiny minority of students (402 out of about 111,000) seem to be engaging Achieve3000…

In the United States today, more jobs than ever before require at least some postsecondary education. Yet too many young adults are either not enrolling or not succeeding in college. This scenario exists across many different types of communities, but schools in rural areas, particularly those with large populations of low-income students, face…

The authors examine the results for students with disabilities from a 2-year randomized controlled trial with students identified in ninth grade and followed through 10th grade in their allotted condition group. Prior to ninth grade, students with disabilities who met criteria for low reading comprehension (i.e., through failure on the state…

Assessing fidelity of implementation is becoming increasingly important in education research, in particular as a tool for understanding variations in treatment effectiveness. Fidelity of implementation is defined as "the determination of how well an intervention is implemented in comparison with the original program design during an efficacy…

Background/Context: Billions of dollars are spent annually on professional development (PD) for educators, yet few randomized controlled trials (RCT) have demonstrated the ultimate impact PD has on student learning. Further, while policymakers and others speak to the role schools should play in developing students' civic awareness, RCTs of PD…

This study used a multiple probe design across participants to examine the effects of classroom simulation using static picture prompts to teach students to make a purchase using a debit card and track expenses by subtracting purchase amounts and adding deposits into a check register. Results demonstrated a functional relation between simulated…

A 2-year, randomized control trial with 9th to 10th grade students with significant reading problems was provided for 50 minutes a day in small groups. Comparison students were provided an elective class and treatment students the reading intervention. Students were identified as demonstrating reading difficulties through failure on their state…

Sustained professional development can support STEM (Science, Technology, Engineering, and Mathematics) reform. The authors describe a 3-year study of sustained professional development for 3 diverse urban schools across the salient factors of fidelity of implementation of project-based learning, development of professional learning communities,…

Proficiency in writing increases opportunities in higher education, employment, and social relationships. Many students in the United States, however, are struggling writers. In particular, the writing performance of students with disabilities in secondary grades continues to lag behind grade level peers. The purpose of this article was to review…
