Statistics education has become an increasingly important component of the mathematics education of today's citizens. In part to address the call for a more statistically literate citizenship, The "Guidelines for Assessment and Instruction in Statistics Education (GAISE)" were developed in 2005 by the American Statistical Association. These…

In the context of a theoretical model of expected profit maximization, this paper shows how historic institutional data can be used to assist enrollment managers in determining the level of financial aid for students with varying demographic and quality characteristics. Optimal tuition pricing in conjunction with empirical estimation of…

In this experiment, syntactic constraints on the retrieval of orthography were investigated using homophones embedded in sentence contexts. Participants typed auditorily presented sentences that included a contextually appropriate homophone that either shared part of speech with its homophone competitor (i.e., was syntactically unambiguous) or had…

This study used an ecobehavioral approach to investigate the conditional probability that English language learning (ELL) students would engage in academic tasks in urban middle school content area classrooms within different instructional grouping configurations. These configurations included whole class, small group, one-to-one, and individual…

Ecuador's 2008 Constitution--and a subsequent law on higher education passed in its wake--effectively suspended student fees for public universities. The goal of this reform was to increase equality of opportunity. In this article I use newly-available individual-level retrospective information from the 2001 Census to explore gender and ethnic…

Often the differences students see in science and mathematics classrooms are in perspective, approach, or application. Understanding those differences can help teachers to present a unified picture of mathematics and science to their students. In this article, the science teacher is given a glimpse of the treatment of topics shared by both…

The first exam in a typical first-semester general chemistry course is used to identify students at risk of failing the course. The performance at Hunter College of 667 students on the first exam in general chemistry in seven different classes between fall 2000 and fall 2005 was correlated with the students' final score in the course. The…

A study was undertaken to implement a series of chance games and activities in a Year 7 classroom, and investigate the students' knowledge about probability concepts, as well as their attitudes to chance. Initially, the project involved selecting a set of appropriate learning activities to develop key probability concepts which are integral to the…

Aim: The aim of this study was to elucidate factors related to the high rate of mental health disorders seen in those with impaired hearing, including social factors and audiological measures. Method: A representative sample of 95 pupils (47 females, 48 males; mean age 11y 1mo, range 6y 5mo to 16y, SD 2y 7mo) with hearing impairments of at least…

Clinical research has found a strong association between negative affect and returning to alcohol use after a period of abstinence. Yet little is known about the probability of a lapse given a particular level of negative affect or whether there is a reciprocal relationship between negative affect and alcohol use across time. The goal of the…

Objective: The authors identified the principal components of bar and nightclub expectancy in college students and the associations between these factors and the risk behavior of nightclubbing. Participants: A total of 4,384 undergraduates enrolled at a large, public university participated. Methods: In the first phase (July-September 2007), the…

Purpose: The purpose of this paper is to measure the relative effect of relevant explanatory variable on smoking tendency and smoking intensity. Design/methodology/approach: Using survey data collected by the Israeli Bureau of Statistics in 2003-2004, a probit procedure is estimated for analyzing factors that affect the probability of being a…

Using social network analysis, we investigated the characteristics of social networks composed of positive relationships (positive network: PN) and negative relationships (negative network: NN) in classrooms of Japanese 3- and 4-year-olds. Analysis of "density" showed that PNs were denser than NNs among 4-year-olds but that this was not…

Prior research indicates that the married enjoy higher levels of well-being than the unmarried, including unmarried cohabiters. Yet, comparisons of married and unmarried persons routinely exclude partnered gays and lesbians. Using a large probability sample, this study assessed how the well-being of partnered gays and lesbians (282) compares with…

Recent trends in the labor force participation of women have brought much public attention to the issue of women opting out. This paper explores the decision of working women to exit the labor market at a time of major transition--the birth of a child--utilizing linked vital statistics, administrative employer, and state welfare records. The…
