This study used simulation (a) to compare the kernel equating method to traditional equipercentile equating methods under the equivalent-groups (EG) design and the nonequivalent-groups with anchor test (NEAT) design and (b) to apply the parametric bootstrap method for estimating standard errors of equating. A two-parameter logistic item response…

The use of random numbers is pervasive in today's world. Random numbers have practical applications in such far-flung arenas as computer simulations, cryptography, gambling, the legal system, statistical sampling, and even the war on terrorism. Evaluating the randomness of extremely large samples is a complex, intricate process. However, the…

Purpose: Language sample analysis is considered by many to be the gold standard for documenting children's oral language skills. One limitation, however, is the time required for collection and transcription of language samples. The goal of this study was to determine if stable language sample measures could be generated using relatively short…

In measurement research, data simulations are a commonly used analytical technique. While simulation designs have many benefits, it is unclear if these artificially generated datasets are able to accurately capture real examinee item response behaviors. This potential lack of comparability may have important implications for administration of…

Single subject research methodology is commonly used and cited in special education courses and journals. This article reviews the types of single subject research designs published in eight refereed journals between 1983 and 2007 used to answer applied research questions. Single subject designs were categorized as withdrawal/reversal, time…

The Problem: This study was designed to analyze the evaluation criteria of the instruments used to evaluate superintendents, the job descriptions for those superintendents, and the goals written as part of their Individual Administrator Professional Development Plans (IAPDPs) to determine whether superintendents are being held accountable for…

Seeking to increase conceptual understanding by sustaining adolescents' engagement and interest in secondary science classrooms, an intervention, the Engagement Model of Academic Literacy for Learning (EngageALL), was designed to implement a disciplinary literacy approach and organize instruction according to characteristics of student interest…

As the accountability standards for schools throughout the nation become more pressing, the relationship between the school superintendent and the local school board has become even more critical to a school's success. A clearer picture of the desired competencies of school superintendents by local boards of education should assist both parties in…

This study identified historical continuities and discontinuities across a century of secondary research published in "English Journal" (1912-1966) and "Research in the Teaching of English" (1967-2011). It highlights considerable methodological continuity across six decades of "English Journal" and some shifts in research emphases that tended to…

The purpose of this study is to measure and present the academic expectation and satisfaction levels of senior class students within Faculty of Economics and Administrative Sciences Faculty of Education of Afyon Kocatepe University comparatively. The population of the study are the students Faculty of Economics and Administrative Sciences and…

When two or more univariate population means are compared, the proportion of variation in the dependent variable accounted for by population group membership is eta-squared. This effect size can be generalized by using multivariate measures of association, based on the multivariate analysis of variance (MANOVA) statistics, to establish whether…

The PIRLS 2011 international database includes data for all questionnaires administered as part of the PIRLS 2011 assessment. This supplement contains the international version of the PIRLS 2011 background questionnaires and curriculum questionnaires in the following 5 sections: (1) Student Questionnaire; (2) Home Questionnaire (Learning to Read…

This longitudinal study examined the relationship between pedagogical continuity in literacy education and early literacy development by comparing Chinese children in Hong Kong and Shenzhen. Stratified random sampling was used to select 24 preschool and Primary 1 classes in four communities catering to middle-class families in each city. The 24…

Computer games are purported to be effective instructional tools that enhance motivation and improve engagement. The aim of this study was to investigate how tertiary student experiences change when instruction was computer game based compared to lecture based, and whether experiences differed between high and low achieving students. Participants…

Continuous exponential families may be employed to find continuous distributions with the same initial moments as the discrete distributions encountered in typical applications of classical equating. These continuous distributions provide distribution functions and quantile functions that may be employed in equating. To illustrate, an application…
