Teachers spend most of their time in school in classrooms, and their instruction and teaching practices may be affected by classroom context such as class size. We examine whether teacher effects interact with classroom context such as class size. Specifically, we seek to determine whether teacher effects are more pronounced in small classes than…

As part of their undergraduate mathematics curriculum, students at Brock University learn to create and use computer-based tools with dynamic, visual interfaces, called Exploratory Objects, developed for the purpose of conducting pure or applied mathematical investigations. A student's Development Process Model of creating and using an…

Parents of children with autism spectrum disorders (ASD) use a wide range of interventions including poorly evidenced dietary interventions. To investigate parents' and professionals' experience of dietary interventions and attitudes towards a proposed trial to evaluate the gluten free casein free diet (GFCFD). Survey of UK parents of…

Achieving fluency with basic subtraction and add-with-8 or -9 combinations is difficult for primary grade children. A 9-month training experiment entailed evaluating the efficacy of software designed to promote such fluency via guided learning of reasoning strategies. Seventy-five eligible first graders were randomly assigned to one of three…

The purpose of this study was to determine the effects of specific practice strategy use on university string players' performance. Participants ('N" = 40) volunteered for the study and were string players enrolled in orchestra at a major research university. Within a pretest-posttest designed study, participants were assigned to…

People of Hispanic origin, including monolingual Spanish speakers, have experienced difficulty identifying with a race category on U.S. demographic surveys. As part of a larger research effort by the U.S. Census Bureau to improve race and Hispanic origin questions for the 2020 Census, we tested experimental versions of race and Hispanic origin…

Pondering a math problem while she swings her sneakered feet from a chair, 12-year-old Andrea Guevara is helping researchers design an assessment that will shape the learning of 19 million students. The 8th grader, who came to the United States from Ecuador three years ago, is trying out two ways of providing English-language support on a…

This paper presents the results of a rigorous experiment examining the impact of pay for performance on student achievement and instructional practice. This study, conducted by the National Center on Performance Incentives in partnership with the RAND Corporation examines an experimental pay for performance program administered via a randomized…

Two proposed style assessment instruments are employed to explore the learning styles of non-English major college students in the EFL (English as a Foreign Language) context in Chinese universities. It was found that their overall learning preferences in English language learning demonstrate a tendency, so that discovering the students' learning…

An educational intervention's effectiveness is judged by whether it produces positive outcomes for students, with the randomized controlled trial (CRT) as a valuable tool for determining intervention effects. However, the intervention-as-implemented in an experiment frequently differs from the intervention-as-designed, making it unclear whether…
