This paper explores the nation's changing child population based on data from the 2010 census. While the number of U.S. children increased only slightly, the demographic shifts within the population were considerable. Some areas of the country (Nevada and Texas) and some demographic groups (including children of mixed race) grew significantly,…

This article points out an unexpected but common misconception by students dealing with the exponential distribution.

Understanding instructors' perceptions of distance education transactions is becoming increasingly important as the mode of distance learning has become not only accepted, but preferred by many students. A need for more empirical data was evident as anecdotal information still dominates the research literature. The study focused on the faculty of…

Congenital amusia is a neurogenetic disorder that affects the processing of musical pitch in speakers of non-tonal languages like English and French. We assessed whether this musical disorder exists among speakers of Mandarin Chinese who use pitch to alter the meaning of words. Using the Montreal Battery of Evaluation of Amusia, we tested 117…

On the 2009 AP[c] Statistics Exam, students were asked to create a statistic to measure skewness in a distribution. This paper explores several of the most popular student responses and evaluates which statistic performs best when sampling from various skewed populations. (Contains 8 figures, 3 tables, and 4 footnotes.)

The purpose of this study was to examine higher education administrators' perceptions of the effectiveness of the Academic Quality Improvement Project (AQIP) as compared to the Program to Evaluate and Advance Quality (PEAQ) within the North Central Association of Colleges and Schools (NCA). The Higher Learning Commission (HLC), a commission of the…

Proposition 209 banned the use of racial preferences in admissions at public colleges in California. We analyze unique data for all applicants and enrollees within the University of California (UC) system before and after Prop 209. After Prop 209, graduation rates increased by 4.4%. We present evidence that certain institutions are better at…

Sourcing data from the National VET Provider Collection and the Higher Education Statistics Collection, this publication provides a summary of participation in tertiary education and training in Australia. It covers participation in Australian Qualifications Framework certificate I qualifications through to doctorates by research, as well as…

When taking mathematics courses, students will sometimes ask their recurring question, "When will I ever use this in real life?" Educators are often unable to provide a direct connection between what they are teaching in the classroom and a real-life application. However, when such an opportunity does arise, they should seize it and…

This study analyzes the increase in school segregation in Delaware from a quantitative perspective. The article tests the hypothesis that the declaration of unitary status that released the Wilmington area school districts from their desegregation order caused the increase in segregation. The research reveals that the declaration of unitary status…

Problem Statement: Preservice teachers acquire the knowledge and skills needed for elementary mathematics education by themselves obtaining quality university educations and by being actively involved in mathematics. Thus, it is essential to make room in teacher education for student-centered projects and activities. Purpose of Study: This study…

The noncentral chi-square approximation of the distribution of the likelihood ratio (LR) test statistic is a critical part of the methodology in structural equation modeling. Recently, it was argued by some authors that in certain situations normal distributions may give a better approximation of the distribution of the LR test statistic. The main…

This article considers effects of construction frequency, form, function, and prototypicality on second language acquisition (SLA). It investigates these relationships by focusing on naturalistic SLA in the European Science Foundation corpus (Perdue, 1993) of the English verb-argument constructions (VACs): verb locative (VL), verb object locative…

Through a review of the literature on the test-frequency effect, we identified several underlying factors that may determine student learning outcome beyond the number of tests administered in a course. A realignment of the conceptual framework of the test-frequency effect with these variables is therefore proposed for future research. However,…

The aim of the current study is to validate the invariance of major profile patterns derived from multidimensional scaling (MDS) by bootstrapping. Profile Analysis via Multidimensional Scaling (PAMS) was employed to obtain profiles and bootstrapping was used to construct the sampling distributions of the profile coordinates and the empirical…
