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…

Empirical Education Inc. is the independent evaluator of WestEd's 2012 i3 Development grant for Internet-based Reading Apprenticeship Improving Science Education (iRAISE). This interim report provides an update on the progress of the randomized control trial (RCT) during the 2014-2015 school year. The RCT measures the impact of iRAISE on student…

A theory-driven approach to evaluation (TDE) emphasizes the development and empirical testing of conceptual models to understand the processes and mechanisms through which programs achieve their intended goals. However, most reported applications of TDE are limited to large-scale experimental/quasi-experimental program evaluation designs. Very few…

The impact of an experimental, one-semester suspension of mathematics and English prerequisites from 12 courses is investigated. Data on enrollment, student performance, and instructor opinions are analyzed for the total group, and results concerning English versus mathematics prerequisites are compared. Implications for further research on the…

This article describes a research study that compared the success of the "adventure playground" to that of a conventional playground. (JA)

Augmentative and alternative communication (AAC) as an area of clinical and educational practice involves a myriad of decisions related to the symbols, devices, and strategies from which each client must choose. These decision-making points can be productively informed through evidence from comparative intervention studies. The purpose of this…

THIS STUDY SOUGHT TO COMPARE THE EDUCATIONAL CHANGES OF EDUCABLE MENTALLY RETARDED CHILDREN ENROLLED IN THE EXPERIMENTAL TWO-TRACK PROGRAM WITH THOSE CHANGES OF MATCHED EDUCABLES ENROLLED IN A ONE-TRACK PLAN. ABOUT 1,800 PUPILS IN CLASSES FOR THE EDUCABLE MENTALLY RETARDED PARTICIPATED IN THIS STUDY. THEY HAD IQ'S RANGING FROM 50-75, WERE FROM 6…

This study compares the reading performance of adolescent and adult neoliterates in Burkina Faso who participated in one of three experimental educational programs with the reading performance of neoliterates who took part in a standard (control) educational program. The experimental programs involved training in phonological awareness, training…

The purpose of this paper is to identify some variations among experimental programs and discuss the manner in which such variations seem to affect a program's success. To accomplish this purpose an in-depth analysis of a few major preschool intervention studies is made in terms of four pertinent variables: (1) Curriculum Model (2) Home…

AN EXPERIMENT WAS CONDUCTED TO TEST THE HYPOTHESIS THAT A GRADUATE-LEVEL COURSE COULD BE TAUGHT EFFECTIVELY WITH A SERIES OF TAPE RECORDED LECTURES. A RESEARCH METHODS CLASS WAS DIVIDED INTO TWO SECTIONS WHICH WERE EQUATED ON THE BASIS OF SCHOLASTIC APTITUDE AS WELL AS SCORES ON TWO DIFFERENT TYPES OF ACHIEVEMENT PRETESTS. THE CONTROL SECTION WAS…

The physiological responses of high (HF) and low fit (LF) individuals at given perceived exercise intensities were compared to ranges provided by the American College of Sports Medicine (ACSM). Participants were 7 LF and 8 HF men between the ages of 22 and 26 years. All participants performed a maximum oxygen uptake and lactate threshold test and…

The "Curriculum for Meeting Modern Problems" was tested by the Project Evaluator in 36 Classrooms in 10 communities within the State of Ohio. Two areas of investigation were established. The first area was conceived as follows: Do students who are subjected to the experimental treatment learn to apply their knowledge about behavior and…
