Data distributions can be represented using different external representations, such as histograms and boxplots. Although the role of external representations has been extensively studied in mathematics, this is less the case in statistics. This study helps to fill this gap by systematically varying the representation that accompanies a task…

The authors assessed correct model identification rates of Akaike's information criterion (AIC), corrected criterion (AICC), consistent AIC (CAIC), Hannon and Quinn's information criterion (HQIC), and Bayesian information criterion (BIC) for selecting among cross-classified random effects models. Performance of default values for the 5…

This study examines the potential benefits of rhyme on young children's word retention during shared reading. In two experiments, 2- to 4-year-old children heard their parent read either a rhymed or non-rhymed version of the same animal story, and were then tested on how many animal names they subsequently recognized from the story in Experiment 1…

The 2007-10 growth spurt (18 percent over three years) in U.S. undergraduate economics degrees stalled out in 2011. Degrees awarded have been relatively constant over the past three years.

This study aims to investigate the students' learning assessment practices used by Jordanian teachers of mathematics for grades (1-6) in Amman. The sample of the study consists of (402) teachers. A questionnaire of (72) items are developed on four domains, namely: questions, homework, exams, and alternative strategies. Validity and reliability are…

The purpose of this study was to explore the degree of grain size of the attributes and the sample sizes that can support accurate parameter recovery with the General Diagnostic Model (GDM) for a large-scale international assessment. In this resampling study, bootstrap samples were obtained from the 2003 Grade 8 TIMSS in Mathematics at varying…

A workforce that can adapt to the fast changing global dynamics is critical for sustainable growth and development. Secondary level segment in the education cycle of a Kenyan plays a key role in the development of this workforce and is important since it de-links one from elementary (primary) learning, provides a chance for one to complete the…

This "First Look" contains national and state totals of revenues and expenditures for public elementary and secondary education for school year 2013-14. This "First Look" includes revenues by source and expenditures by function and object, including current expenditures per pupil and instructional expenditures per pupil. This…

In light of the emergence of statistical analysis techniques based on data mining in education sciences, and the potential they offer to detect non-trivial information in large databases, this paper presents a procedure used to detect factors linked to academic achievement in large-scale assessments. The study is based on a non-experimental,…

The purpose of this study is to investigate physical education teacher attitudes towards the effectiveness of sport activities in north-east Badia. The study population consisted of all teachers of physical education who are studying curriculum of physical education in schools affiliated to the Directorate of Education of the brigade desert…

The use of e-learning techniques in higher education is becoming ever more frequent. In some institutions, e-learning has completely replaced the traditional teaching methods, while in others it supplements classical courses. The paper presents a study conducted in a member institution of the University of Ljubljana that provides public…

This publication provides data on Australian Qualifications Framework (AQF) programs completed from 2010 to 2014 in Australia's government-funded vocational education and training (VET) system (broadly defined as all activity delivered by government providers and government-funded activity delivered by community education and other registered…

We describe a web-based interactive graphic that can be used as a resource in introductory classes in mathematical statistics. This interactive graphic presents 76 common univariate distributions and gives details on (a) various features of the distribution such as the functional form of the probability density function and cumulative distribution…

Subscores, also known as domain scores, diagnostic scores, or trait scores, can help determine test-takers' relative strengths and weaknesses and appropriately focus remediation. However, subscores often have poor psychometric properties, particularly reliability and distinctiveness (Folske, Gessaroli, & Swanson, 1999; Monaghan, 2006;…

This dissertation examines two related questions. "How do mixed membership models work?" and "Can mixed membership be used to model how students use multiple strategies to solve problems?". Mixed membership models have been used in thousands of applications from text and image processing to genetic microarray analysis. Yet…
