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…

The "Census in Schools Educator Update" is sent to educators and educational organizations periodically to keep them informed about current and upcoming census data and to provide ideas about how to use data in the classroom. This issue of the "Census in Schools Educator Update" newsletter includes the following items: (1) Census in Schools and…

This paper presents an agent-based educational environment to teach argument analysis (ALES). The idea is based on the Argumentation Interchange Format Ontology (AIF)using "Walton Theory". ALES uses different mining techniques to manage a highly structured arguments repertoire. This repertoire was designed, developed and implemented by us. Our aim…

Principals are often overwhelmed by the sheer amount of data they have and are unsure how to use the information. When the authors talk about "data," they mean all the information principals have or might collect that can support their work with teachers to make their school more rigorous. The authors believe that data can guide decision making,…

Factor-analytic research is common in the study of constructs and measures in psychological assessment. Latent factors can represent traits as continuous underlying dimensions or as discrete categories. When examining the distributions of estimated scores on latent factors, one would expect unimodal distributions for dimensional data and bimodal…

Using statistic indicators as vectors of information relative to the operational status of a phenomenon, including a religious one, is unanimously accepted. By introducing a system of statistic indicators we can also analyze the interfacing areas of a phenomenon. In this context, we have elaborated a system of statistic indicators specific to the…

This article discusses the effect of clustering on statistical tests conducted with school environment data. Because most school environment studies involve the collection of data from teachers nested within schools, the hierarchical nature to these data cannot be ignored. In particular, this article considers the influence of intraschool…

Caregivers reported on sleep in a convenience sample of 90 children with fragile X syndrome utilizing a standardized assessment tool, the Children's Sleep Habits Questionnaire (CSHQ), and a 14-day sleep diary. CSHQ data indicated that 47% of participants had sleep problems at a level that suggested referral and further evaluation. Sleep diary data…

Formative assessment provides a means to successfully scaffold learning. Unfortunately, few teachers understand the pedagogical implications of such scaffolding or their role in utilizing formative assessments. The purpose of our study was to develop an understanding of the experience of being a teacher that is seeking to improve learning through…

Introductory business statistics students often receive little guidance on how to apply the methods they learn to further business objectives they may one day face. And those students may fail to see the continuity among the topics taught in an introductory course if they learn those methods outside a context that provides a unifying framework.…

If you are looking for an organic approach to purpose-driven professional learning, this is the book for you. Award-winning educator Lois Brown Easton's latest work provides a compelling case study in narrative form, a chronological PLC planning outline, and first-hand "lessons learned" about how PLCs develop, mature, and sustain themselves. You…

Education and earnings interact in complex and often unexpected ways--but there are rules to the game. "The College Payoff," a new paper from the Georgetown University Center on Education and the Workforce, uses in-depth data analysis to identify, illuminate and elucidate those rules. This executive summary provides a glimpse of the education and…

Making the transition from arithmetic to mathematics, especially algebra, is critical to future academic and economic success, yet many students find this transition difficult and success in algebra elusive. This paper reports on the outcomes achieved from a three year course of professional development, POWERSOURCE[c], that helped teachers apply…

"Achieving Fluency" presents the understandings that all teachers need to play a role in the education of students who struggle: those with disabilities and those who simply lack essential foundational knowledge. This book serves teachers and supervisors by sharing increasingly intensive instructional interventions for struggling students on…

Previous research served as the platform for this study's research question: Does math anxiety mediate the relation between parental involvement and mathematics achievement? The primary purpose of this study was to examine this mediation model in a sample of at-risk second graders. Due to previous research, the investigators hypothesized that math…
