New knowledge tracing models are continuously being proposed, even at a pace where state-of-the-art models cannot be compared with each other at the time of publication. This leads to a situation where ranking models is hard, and the underlying reasons of the models' performance -- be it architectural choices, hyperparameter tuning, performance…

Proactive preliminary minimum sample size determination can be useful for the early planning stages of a latent variable modeling study to set a realistic scope, long before the model and population are finalized. This study examined existing methods and proposed a new method for proactive preliminary minimum sample size determination.

In preparation for online administration of the ACT® test, ACT conducted studies to examine the comparability of scores between online and paper administrations, including a timing study in fall 2013, a mode comparability study in spring 2014, and a second mode comparability study in spring 2015. This report presents major findings from these…

The purpose of this study was to examine the extent to which the measures that make up each of the three separate accountability indices of school performance in South Carolina could be used to create an overall, reliable index of school performance. Data from public elementary, middle, and high schools in 2012/13 were used in confirmatory factor…

The Research Alliance for New York City Schools examined Department of Education (DOE) School Survey data from 2008-2010 to better understand the richness and complexities of the information elicited by the Survey from parents, students, and teachers. This document provides the appendices to the technical report "New York City School Survey…

This technical document provides guidance to educators on the creation and interpretation of survey instruments, particularly as they relate to an analysis of program implementation. Illustrative examples are drawn from a survey of educators related to the use of the easyCBM learning system. This document includes specific sections on…

Within the general framework of a multifactor term structure model, the fundamental partial differential equation (PDE) satisfied by a default-free zero-coupon bond price is derived via a martingale-oriented approach. Using this PDE, a result characterizing a model belonging to an exponential affine class is established using only a system of…

Combines costs of fund raising and college-relations data for each of 3 years from 17 colleges and universities with the schools' institutional characteristics to predict ratios of alumni donors to each school's total alumni. With factor analysis, classifies expenditure and institutional variables according to fund-raising effort, donor wealth,…

New Zealand librarians, using 95 indicators of performance, rated their libraries highest on service indicators and lowest on local government relations. Factor analysis was used to derive 13 dimensions of effectiveness. The indicators ranked highest in a prior survey of stakeholders are spread across nine of the dimensions, which fit four models…

The multiplicity of variables describing the financial conditions of postsecondary institutions makes it difficult to assess changes in higher education finance from year to year and to find the relationship between these finance variables and average faculty salaries. This study sought to determine if a small number of factors could be derived to…

Recent developments in dichotomous factor analysis based on multidimensional item response models (Bock and Aitkin, 1981; Muthen, 1978) provide an effective method for exploring the dimensionality of questionnaire items. Implemented in the TESTFACT program, this "full information" item factor analysis accounts not only for the pairwise…

Over the past 15 years a body of research has investigated organizational transitions in adolescent development. Researchers studying school transitions exclusively ask whether significant transition affects students' social and psychological development. To test the presence of transition effects, researchers have typically observed mean…

This technical report describes the development, pilot testing, and revision of a survey instrument designed to measure secondary school teachers' perceptions of their efficacy working with students from diverse backgrounds. A brief review of relevant literature frames the current study in the context of survey development that is technically…

This study examined the relationship between perceptions of diversity and overall satisfaction in students at the University of Maryland at College Park. An anonymous 100-item questionnaire on cultural attitudes and climate was mailed to first and third year students, with mail and phone call follow-ups resulting in an overall return rate of 60…
