Using a "naïve" specification, this paper estimates the relationship between 36 high school characteristics and 24 student outcomes controlling for students' pre-high school characteristics. The goal of this exploration is not to generate casual estimates, but rather to: (a) compare the size of the relationships to determine which inputs…

This article provides a detailed discussion of the theory and practice of modern regression discontinuity (RD) analysis for estimating the effects of interventions or treatments. Part 1 briefly chronicles the history of RD analysis and summarizes its past applications. Part 2 explains how in theory an RD analysis can identify an average effect of…

This paper considers how the idea of "discipline" can best be conceptualised, both in general and particular terms. Much previous research has employed a strong essentialist approach, a model of disciplines which exaggerates the homogeneity of specific disciplinary features and accords disciplines generative powers which they rarely…

This paper examines the causal impacts of Hong Kong's 1971 policy of free compulsory education on students' educational attainment. Using a regression discontinuity method and Hong Kong Census data, this study compares children born just before and just after the month in which the compulsory-education law came into effect. The results show that…

Item response theory parameters have to be estimated, and because of the estimation process, they do have uncertainty in them. In most large-scale testing programs, the parameters are stored in item banks, and automated test assembly algorithms are applied to assemble operational test forms. These algorithms treat item parameters as fixed values,…

In this article, a 2-way multigroup common factor model (MG-CFM) is presented. The MG-CFM can be used to estimate interaction effects between 2 grouping variables on 1 or more hypothesized latent variables. For testing the significance of such interactions, a likelihood ratio test is presented. In a simulation study, the robustness of the…

Recently a new mean scaled and skewness adjusted test statistic was developed for evaluating structural equation models in small samples and with potentially nonnormal data, but this statistic has received only limited evaluation. The performance of this statistic is compared to normal theory maximum likelihood and 2 well-known robust test…

Curriculum-Based Measures in writing (CBM-W) assesses a variety of fluency-based components of writing. While support exists for the use of CBM measures in the area of writing, there is a need to conduct further validation studies to investigate the utility of these measures within elementary and secondary classrooms. Since only countable indices…

"Student Debt and the Class of 2014" is the tenth annual report on the student loan debt of recent graduates from four-year colleges. It documents the latest rise in student loan debt and finds considerable variation among states as well as colleges. It also includes a new analysis of how debt at graduation has changed over the last…

Minnesota Reading Corps is the largest AmeriCorps State program in the country. Its mission is to help every Minnesota child become a proficient reader by the end of third grade. To meet this goal, the Minnesota Reading Corps and its host organization, ServeMinnesota Action Network, engages a diverse group of AmeriCorps members to provide…

Many research studies involving Pearson correlations are conducted in settings where one of the two variables has a restricted range in the sample. For example, this situation occurs when tests are used for selecting candidates for employment or university admission. Often after selection, there is interest in correlating the selection variable,…

Do teachers assess same-race students more favorably? This paper uses nationally representative data on teacher assessments of student ability that can be compared with test scores to determine whether teachers give better assessments to same-race students. The data set follows students from kindergarten to grade 5, a period during which racial…

Research on the effectiveness of competence-based education (CB-education) across educational contexts and levels requires a new evaluation measurement. This study explores the face validity, construct validity, and robustness of a competency self-report instrument that is aligned with contemporary competence theory and with current educational…

A simulation study was conducted to explore the performance of the linear logistic test model (LLTM) when the relationships between items and cognitive components were misspecified. Factors manipulated included percent of misspecification (0%, 1%, 5%, 10%, and 15%), form of misspecification (under-specification, balanced misspecification, and…

Compressed sensing (CS) is an emerging signal acquisition framework that goes against the traditional Nyquist sampling paradigm. CS demonstrates that a sparse, or compressible, signal can be acquired using a low rate acquisition process. Since noise is always present in practical data acquisition systems, sensing and reconstruction methods are…
