The Cox proportional hazards model and the accelerated failure time model are frequently used in survival data analysis. They are powerful, yet have limitation due to their model assumptions. Quantile regression offers a semiparametric approach to model data with possible heterogeneity. It is particularly powerful for censored responses, where the…

This paper analyzes five linear equating models for the "nonequivalent groups with anchor test" (NEAT) design with internal anchors (i.e., the anchor test is part of the full test). The analysis employs a two-dimensional framework. The first dimension contrasts two general approaches to developing the equating relationship. Under a "parameter…

The goal of this research is to understand how students define teaching effectiveness. By using multivariate regression analysis of 8,000+ student evaluations of teaching compiled by a School of Criminal Justice at a Midwestern public university, this paper explores the relationships between individual indicators of instructor performance (e.g.…

Higher education in Australia is undergoing a comprehensive reform with particular focus on higher levels of attainment by increasing access to university study for Australians from all backgrounds. To support the government's ambition of around 217,000 additional graduates by 2025, it has committed to removing caps and funding student places on…

Reflection on events at work, including errors is often as a means to learn effectively through work. In a cross-sectional field study in the banking sector, we investigated attitudes towards workplace errors (i.e. error orientation) as predictors of reflective activity. We assumed the organisational climate for psychological safety to have a…

The purpose of this research is to develop an understanding of the factors that support or constrain the individual's sharing knowledge in the organization. The current study seeks to explore whether personality (self-efficacy and self-esteem) and situational (cognitive appraisal: threat versus challenge) characteristics influence participants'…

For the purposes of tailoring physics instruction in accordance with the needs and abilities of the students it is useful to explore the knowledge structure of students of different ability levels. In order to precisely differentiate the successive, characteristic states of student achievement it is necessary to use test items that possess…

Students receive abundant information about their educational performance, but how this information affects future educational-investment decisions is not well understood. Increasingly common sources of information are state-mandated standardized tests. On these tests, students receive a score and a label that summarizes their performance. Using a…

The revision and renewal of the Elementary and Secondary Education Act of 1965 will likely expand its parental involvement component to engage educators, parents, and community partners in supporting public education for children. This revisions call for best practices, but current literature fails to identify specific activities associated…

Instructional strategies in science that fail to identify students' initial understanding of scientific concepts may leave students' flawed ideas unchanged, thus affecting their ability to synthesize, differentiate, and connect to new information in science. The purpose of this quantitative study was to examine the relationship between concept…

Improvement of educational attainment in schools in urban, disadvantaged areas is an important priority for policy--particularly in countries like England which have a long tail at the bottom of the educational distribution and where there is much concern about low social mobility. An anomaly in the spatial dimension of school funding policy in…

The size and dynamism of the Web poses challenges for all its stakeholders, which include producers/consumers of content, and advertisers who want to place advertisements next to relevant content. A critical piece of information for the stakeholders is the demographics of the consumers who are likely to visit a given web site. However, predicting…

This study presents a case for applying a transformation (Box and Cox, 1964) of the criterion used in predictive validity studies. The goals of the transformation were to better meet the assumptions of the linear regression model and to reduce the residual variance of fitted (i.e., predicted) values. Using data for the 2008 cohort of first-time,…

This study uses Monte Carlo simulations to demonstrate that regression-discontinuity designs arrive at biased estimates when attributes related to outcomes predict heaping in the running variable. After showing that our usual diagnostics are poorly suited to identifying this type of problem, we provide alternatives. We also demonstrate how the…

There is a common misperception that test scores do not predict above a minimum threshold (Sackett, Borneman, & Connelly, 2008). That is, test scores may be useful for identifying students with very low levels of ability; however, higher scores are considered unrelated to higher performance for those above a certain threshold. This study aims…
