The objective of this study was to evaluate nutrition knowledge, attitudes and practices in Bahrain. A cross-sectional survey was carried out in 1998. Highly statistically significant differences (p less than 0.0001) were observed between practitioners and students in relation to knowledge concerning recommended daily allowance. The results…

Many extant studies on the use of non-parental child care are based on data from the youngest child in the household. To date, it has not been addressed whether this approach introduces bias. We present reasons why child care arrangements for youngest children may differ from those of same-age older children and examine whether the use of child…

The psychological literature currently emphasizes reporting the "effect size" of research findings in addition to the outcome of any tests of significance. However, some confusion may result from the fact that there are three distinct uses of effect sizes in the psychological literature, namely, power analysis, research synthesis, and research…

A study was conducted to investigate the teaching methods valued and used by faculty in Arkansas public higher education institutions at the freshman and sophomore levels. The participants were 336 teachers who responded to a 21 item survey distributed to college teachers in Arkansas. The study sought to collect relevant demographic data and to…

The purpose of this study was to examine students' levels of engagement in educational practices by enrollment status, time of enrollment, and size of college in community colleges. Specifically, this study assessed the quality of the undergraduate education through students' self-reported data about their academic and nonacademic activities. The…

This report summarizes the findings from a national evaluation of mentoring programs funded under the U.S. Department of Education's Student Mentoring Program. The impact evaluation used an experimental design in which students were randomly assigned to a treatment or control group. Thirty-two purposively selected School Mentoring Programs and…

Since the mid-1960s, when illicit drug use burgeoned in the normal youth population, substance use by American young people has proven to be a rapidly changing phenomenon. Smoking, drinking, and illicit drug use are leading causes of morbidity and mortality, both during adolescence as well as later in life. How vigorously the nation responds to…

The number of online education courses available to those seeking higher education have been increasing exponentially, offering opportunities to students who would not otherwise have been able to do so, as well as offering options for those who may have been able to attend classes on campus, but would prefer to pursue their course of study at…

This exploratory research study examined the impact of using feedback from weekly multiple-choice tests on final exam scores and students' IDEA course ratings. The teacher researcher taught two sections (N=33; N=34) of a graduate-level, semester-long, online course in advanced human growth and development. Each section had identical course…

This research explored the degree to which group sizes can differ before the robustness of analysis of variance (ANOVA) and analysis of covariance (ANCOVA) are jeopardized. Monte Carlo methodology was used, allowing for the experimental investigation of potential threats to robustness under conditions common to researchers in education. The…

Conventional statistical significance tests do not inform the researcher regarding the likelihood that results will replicate. One strategy for evaluating result replication is to use a "bootstrap" resampling of a study's data so that the stability of results across numerous configurations of the subjects can be explored. This paper…

This paper summarizes an experiment conducted to examine the counting performance of 7- and 8-year-olds. Analysis of variance was computed on counting errors produced when enumerating a set of squares on a computer screen. The factors included in the analysis were age, gender, array size, error type, proximity, and error form. The primary…

Statistical significance is often inappropriately equated with evaluating result importance and evaluating result replicability, even though these are three somewhat different issues. The prudent researcher must separately assess each of these elements of the "research triumvirate" by using different methods. This paper focuses on two…

Concerned with imprecision in researchers' use of the word, "interpretive," this report draws from the work of Max Weber to describe the characteristics of an interpretive science of organizational communication and then briefly lists some advantages of following the interpretive approach. First examining the role of subjective meaning…

Numerous designs using analysis of variance (ANOVA) to test ordinal hypotheses were assessed using a Monte Carlo simulation. Each statistic was computed on each of over 10,000 random samples drawn from a variety of population conditions. The number of groups, population variance, and patterns of population means were varied. In the non-null…
