The purpose of this study was to describe the differences of teachers with and without National Board Certification in relation to their percentages of student competency in high school physical education. Data from the South Carolina Physical Education Assessment Program (SCPEAP) were used as the measure of student competency. Student competency…

This study examined the effects of training on peer assessment and comments provided regarding oral presentations in EFL (English as a Foreign Language) classrooms. In Study 1, both the treatment and control groups received instruction on skill aspects, but only the treatment group was given an additional 40-minute training on how to rate…

This study determined the effectiveness of Kindergarten Peer-Assisted Learning Strategies (K-PALS) for English Learners (ELs). We compared 20 K-PALS ELs to 20 Control ELs and to 20 K-PALS non-ELs on early reading skill acquisition, using a pretest-posttest control group design with matched samples. We also compared proportions of ELs unresponsive…

A persistent problem in the evaluation of field-based projects is the lack of no-treatment comparison groups. Frequently, potential comparison groups are confounded by socioeconomic, racial, or other factors. Among the possible methods for dealing with this problem are various matching procedures, but they are cumbersome to use with multiple…

A relationship between experimental and statistical controls is considered in an effort to show how this relationship affects the power of an experiment. Statistical rather than experimental controls are often used to reduce the effect of subjects at the extremes of individual difference. This results in attrition of actual experimental subjects.…

The purpose of the study was to determine whether higher shorthand speeds were achieved by high school students in a 1-year shorthand course through the use of Simplified Gregg Shorthand or through the use of Diamond Jubilee (DJ) Gregg Shorthand. The control group consisted of 75 students enrolled in Simplified Shorthand during the years…

In a public school setting administrators are frequently under local pressure to make a new project service available to all eligible children. However, comparable control groups for project evaluation are often absent, and although random assignment to treatment groups remains the most systematic method of providing controls, this is not often…

The relationship of speech training to the written English of selected Negro students using substandard English in an elementary school was investigated. The limitations to the study are: (1) The elementary school is a small rural school with an enrollment of about 500 white and 80 Negro students; (2) The school has only one part-time speech…

The quality of research on groups has been notoriously poor. This article is an attempt to respond to the research and evaluation deficit by providing some methodological approaches that might encourage group researchers and practitioners to attempt high quality research. (Author)

To study the effects of planned seriation experiences on the acquisition and retention of seriation abilities of four-year-old children, fifty children from four preschool centers were assigned to control and experimental groups and tested before and after exposure to the experiences. Data analysis indicated that the experimental group had higher…

Eighty preschoolers participated in a study of the usefulness of the lure-retrieval paradigm. Four treatment conditions were compared: In addition to play and training conditions, a questions condition and an alternative-materials control group were employed. Results prompted discussion of theoretical and methodological issues surrounding the…

The need to attend to both methodological and social concerns is demonstrated in two examples: one where the unchecked effects of the social consequences of a methodologically rigorous research design invalidated the evaluation and a second where explicit trade-offs between methodological rigor and social costs enabled the evaluation to proceed.…

The effects of fluency intervention strategies on students fluency rate, comprehension, and word identification were the focus of this study. Both the experimental and control groups were first grade classes, taught by the same teacher, at Elder Primary School in Sandersville, Georgia. The study was conducted over a 15-week period. The results of…
