In this study we examined the effects of online follow-up and online peer interaction following a face-to face professional development workshop on attitudes towards that professional development and completion of a professional development task. School librarians were invited to work online on a three page plan outlining interventions a library…

A major tenet of both the Individuals with Disabilities Education Act and the No Child Left Behind Act is the identification and use of evidence-based practices, or those instructional techniques shown by research as most likely to improve student outcomes meaningfully. However, much confusion exists regarding the meaning and potential…

Using evidence-based practices, or those instructional techniques shown by research to improve student outcomes meaningfully, increases the performance of students with disabilities and should therefore be a priority for special educators. But how does a practice come to be considered evidence based? The unique characteristics of group…

Tests of mean equality proposed by Alexander and Govern (1994) and Tsakok (1978) were compared to the well-known procedures of Brown and Forsythe (1974), James (1951), and Welch (1951) for their ability to limit the number of Type I errors in one-way designs where the underlying distributions were nonnormal, variances were nonhomogeneous, and…

This digest offers tips on designing questionnaires and on avoiding common design errors. The following useful suggestions are offered: (1) keep the questionnaire brief and concise; (2) get feedback on the initial list of questions developed; (3) locate personal or confidential questions at the end of the questionnaire; (4) put categories in…

With the advent of the computer and user-friendly statistical software packages, factor analysis has become accessible to most researchers. However, conventional factor analysis, or R-technique, is only useful for research concerning types or groups of variables. Educational and psychological researchers are often interested in types of people,…

The 1994 National Assessment of Educational Progress (NAEP) monitored the performance of students in American schools in reading, U.S. history, geography, mathematics, science, and writing. The sample involved more than 135,000 public and private school students who were 9, 13, or 17 years old and/or in grades 4, 8, and 12. This technical report…

Social penetration has been described by S.W. Littlejohn (1992) as "the process of increasing disclosure and intimacy in a relationship." The phrase "social penetration" originated with I. Altman and D. Taylor, the foremost researchers in this area. From other theories, Altman and Taylor developed a unified theory which…

This paper discusses self-assessment--i.e., the act of evaluating or monitoring one's own level of knowledge, performance, and understanding--in a metacognitive framework, taking into account the contexts in which self-assessment occurs. It begins with a brief review of metacognitive and social psychology theories that pertain to self-assessment.…

A study examined the mass media research literature to determine if there was a dominant paradigm in the field. The mass media research published in eight communication journals from 1965 to 1989 was content analyzed to identify paradigm, orientation (focus and theory), data (type, source, and sample), methodology (type and manipulation), and…

In psychological and special education research, group comparison experimental designs are more often used than single subject experimental designs. However, the application of group designs poses many difficulties, such as the collection of large numbers of homogeneous subjects for a particular experimental condition, the averaging of individual…

This paper addresses research issues and strategies with regard to studying the educational treatment of the black college athlete. The paper begins with an explanation of four intitial premises, after which problem areas are identified indicating that: for athletic students, admissions may be based primarily on athletic promise; in the high…

Although it is widely known that special assumptions are needed for univariate analysis of repeated measures data, researchers seldom examine their data for violation of these assumptions. This paper reviews ways in which repeated measures analyses are usually handled and describes limitations of these methods. A design with two within subject…

Experimenters sometimes wish to estimate for a particular dependent variable the proportion of total group variance that is associated with mean differences among fixed treatments or subject classifications. Hays (1981) represents this proportion by the parameter omega squared. A point estimate may be easily computed as a function of the number of…
