The primary aim of the present study was to investigate whether variations exist in child and parent attributions in predicting child academic achievement within a culture and between cultures. Participants were 158 students and their parents from three different primary schools in Hong Kong, including one British international school consisting…

Background: Speaking rate has implications for both clinical practice and an understanding of normal and disordered communication processes. Fundamental information on speaking rate is required by the clinician for the appropriate management of those disorders with disturbances of rate or those in which rate modification strategies are applied.…

Dropping out of school has been presented as a serious problem affecting gifted students, with some authors suggesting that 20% or more of dropouts could be gifted (e.g., Rimm, 1995; Robertson, 1991). Longitudinal data from North Carolina were used to investigate high-school dropout rates among gifted students (N = 7916) who had participated in a…

This article looks at how children between the ages of 4 and 8 years report they feel when they are exposed to passive smoking and how they react in these situations. Data were collected annually from a cohort of 250 primary school children, which was tracked from their Reception Classes to Year 3 across six Liverpool schools. Quantitative and…

When she was asked to write an article on how she used quantitative research methods in her doctoral dissertation, the author eagerly jumped at the chance. Not because she is some sort of expert on the topic, but rather because she wishes someone had given her some insights into the journey she was about to embark on. Although the course work for…

Background: We used variable threshold models which accounted for age and gender differences to investigate the genetic and environmental influences on DSM-IV conduct disorder (CD) at the level of symptoms, aggressive versus non-aggressive domains, and full-scale. Method: A community sample of 1100 twin pairs (age 11-18) was interviewed using the…

Business students are typically introduced to the concept of process management in their introductory course on operations management. A very important learning outcome here is an appreciation that the management of processes is a key to the management of quality. Some of the related concepts are qualitative, such as strategic and behavioral…

Teaching quantitative courses can be challenging. Similarly, layout modeling and lean production concepts can be difficult to grasp in an introductory OM (operations management) class. This article describes a simulation model developed in PROMODEL to facilitate the learning of layout modeling and lean manufacturing. Simulation allows for the…

This study presents a continuing investigation of influences on outcomes achieved by students working in groups of three on tasks related to chance and data. Earlier research described final mathematical outcomes and identified 17 factors influencing three types of short-term outcomes for groups working in an "isolated setting." The current report…

Admissions data and first-year grade point average (GPA) data from 11 graduate management schools were analyzed to evaluate the predictive validity of Graduate Management Admission Test[R] (GMAT[R]) scores and the extent to which predictive validity held across sex and race/ethnicity. The results indicated GMAT verbal and quantitative scores had…

This study investigated the effect of Computer Assisted Language Learning (CALL) on elementary-prep school students' improvement in English as a foreign language (EFL). Eightythree students in Al-Tamayoz Elementary-prep School, United Arab Emirates, were selected and divided into experimental and control groups (43 and 40 participants…

This study investigated introductory statistics students' conceptual understanding of the standard deviation. A computer environment was designed to promote students' ability to coordinate characteristics of variation of values about the mean with the size of the standard deviation as a measure of that variation. Twelve students participated in an…

Children and adolescents in the United States are increasingly overweight at younger ages. Many studies have investigated the issue from the perspective of professionals and other adults. This study assessed early adolescents' perceptions regarding the magnitude of, effects of, causes of, solutions for, and learning preferences related to…

This paper describes a classroom teaching experiment, concerning the concept of probability, with children aged 5 in a kindergarten school. The teaching experiment was based on constructivist and interactionist theories about the learning of school mathematics and lasted one month. The collection of the information was based on the tape-recorded…

A quasi-experimental research design with quantitative and qualitative methodologies was conducted to explore reactions of 21 students to treatment manuals for substance abuse. Students were randomized to experimental (n = 11) and attention-control (n = 10) groups involving exposure to one of two manual-based therapy interventions. Quantitative…
