We conducted a 14-week experimental study of 2 versions of a relatively comprehensive RC intervention that involved 50 classroom teachers, 15 tutors, and 116 children drawn in equal proportions from grades 3 and 5 in 13 schools in a large urban school district. Students were randomly assigned in equal numbers to the two tutoring conditions and a…

Argumentative thinking requires not only the "skill" to apply argumentative strategies such as supporting theories with evidence but also the "will" to apply these strategies by considering argumentative thinking to be both reasonable and worthwhile. Focusing on direct instruction for the initial acquisition of both skill and…

Students training to become primary school teachers appear to have little awareness of the core concepts of geography (teaching). To ensure that future primary school teachers are able to develop their pupils' geographical awareness, a six weeks programme was developed. The characteristics of this programme -- named Consciously Teaching Geography…

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…

Project GOAL is a systematic dropout prevention model including individual and peer-mediated group interventions for at-risk students. This article provides an overview of the Project GOAL model and describes a 2-year experimental pilot study of Project GOAL with a cohort of eighth-and ninth-grade students in a low-income school district in the…

This study investigated the effectiveness of oral metalinguistic feedback and recasts as well as the effect of focused tasks (FT) in the development of implicit and explicit knowledge during video-conference interactions. This was accomplished by partial replication of a study performed in a classroom setting. Three groups of Brazilian EFL…

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…

Adapting support contingently to student needs by first diagnosing their current understanding, that is, scaffolding, is considered a key aspect of excellent teaching. The use of classroom scaffolding is rare, however. We therefore investigated the benefits to teachers of a professional development program that was based upon a model of contingent…

Districts expend a considerable amount of time, effort, and resources providing student performance data to teachers to inform instruction, and examining those data for organizational decision-making. Yet rarely, if ever, are these outcome data connected to what goes on in classrooms. In this experimental study, the author reports on the…

This experimental study investigated whether computer-based video games facilitate children's cognitive learning. In comparison to traditional computer-assisted instruction (CAI), this study explored the impact of the varied types of instructional delivery strategies on children's learning achievement. One major research null hypothesis was…

Solution-focused counseling departs from problem-solving strategies by identifying what individuals are already doing well and building on those strengths. Presents the basic concepts of solution-focused counseling and their applications to groups, group session descriptions with case illustrations, and the preliminary results of a counselor…

The Evaluation of the Emergency School Assistance Program (ESAP) for the 1971-72 school year is the first application of full-blown experimental design with randomized experimental and control cases in a federal evaluation of a large scale program. It is also one of the very few evaluations which has shown that federal programs can raise tested…

The second of two final reports covering the second phase of a research program designed to maximize social and occupational adjustment of rural youth presented baseline data gathered for use in a future (February 1974) evaluation of program effectiveness. A model program for rural youth in the North Central States, the results of previous…

The project was designed to demonstrate the feasibility and effectiveness of providing faster, more relevant, and more comprehensive diagnostic services to vocational rehabilitation clients with a wide range of disabilities.
