To measure individual difference in latent attributes more precisely, this study proposed a new cognitive diagnosis model (CDM), which is referred as the probabilistic-inputs, noisy conjunctive (PINC) model, by treating the deterministic binary latent attributes as probabilistic, and directly estimating the probability in the model. Simulation…

In this article, I utilize a regression discontinuity design to estimate the effects of Tulsa Achieves--a prevalent and understudied type of tuition-free college program. In contrast to concerns regarding tuition-free community college suppressing bachelor's degree attainment, I find that Tulsa Achieves increased the likelihood of transferring to…

A free higher education policy was implemented in Ecuador in 2008. This article analyzes whether the effect of this policy has contributed to eliminating access barriers through the evaluation of a set of socioeconomic, demographic variables, and others related to educational policies concerning the admission process implemented in 2012. It is…

Approximately one in 10 children in the United States is diagnosed with attention-deficit/hyperactivity disorder (ADHD), a disability that can negatively affect academic achievement, yet relatively few children with ADHD are in special education. To better understand factors that determine which students with ADHD are in special education, we…

The purpose of this study was to examine the enrollment patterns in Vermont's universal, mixed-delivery prekindergarten (preK) program and the child characteristics associated with the likelihood of being enrolled in different program types. This study describes the characteristics of children enrolled in universal preK programs in 2016/17, which…

Vermont passed universal prekindergarten (preK) legislation in 2014 (Act 166) in an effort to increase access to quality preK programs for all young children in the state. Act 166 provides state funded preK to all olds (and to 5 year olds who are not eligible for kindergarten). Families can enroll their children at no cost in any prequalified preK…

Vermont passed universal prekindergarten (preK) legislation in 2014 (Act 166) in an effort to increase access to high-quality preK programs for all young children in the state. Act 166 provides state-funded preK to all 3- and 4-year-olds (and to 5-year-olds who are not eligible for kindergarten). Families can enroll their children at no cost in…

These are the appendixes for the report "Enrollment Rates of Children in Universal Prekindergarten Programs in Vermont in 2016/17. REL 2020-015." The purpose of this study was to examine the enrollment patterns in Vermont's universal, mixed-delivery prekindergarten (preK) program and the child characteristics associated with the…

To increase opportunities for students to take more advanced math courses in high school, many school districts enroll grade 8 students in Algebra I, a gateway course for advanced math. But students who take Algebra I in grade 8 and skip other math courses, such as grade 8 general math, might miss opportunities to develop the foundational…

For 25 years, nearly 3,000 colleges and universities have used the Ruffalo Noel Levitz (RNL) Satisfaction-Priorities Surveys to assess their students, strengthen the student experience, increase student success and completion, and prioritize campus planning initiatives. The surveys are valued so highly because they reveal where institutions are…

This article provides a brief overview and comparison of three matching approaches in forming comparable groups for a study comparing test administration modes (i.e., computer-based tests [CBT] and paper-and-pencil tests [PPT]): (a) a propensity score matching approach proposed in this article, (b) the propensity score matching approach used by…

This article describes the incorporation of a dice game (piggy) to teach food safety hazards and risk in an engaging way in HACCP classes. Each player accumulates points by rolling two dice, but loses points in a turn when rolling a 7, or all accumulated points when rolling two consecutive doubles. This game helps explain the difference between a…

Estimating the prerequisite structure of skills is a crucial issue in domain modeling. Students usually learn skills in sequence since the preliminary skills need to be learned prior to the complex skills. The prerequisite relations between skills underlie the design of learning sequence and adaptation strategies for tutoring systems. The…

Despite the popularity of propensity score (PS) techniques they are not yet well studied for matching multilevel data where selection into treatment takes place among level-one units within clusters. This paper suggests a PS matching strategy that tries to avoid the disadvantages of within- and across-cluster matching. The idea is to first…

In this article, we propose using the Bayes factors (BF) to evaluate person fit in item response theory models under the framework of Bayesian evaluation of an informative diagnostic hypothesis. We first discuss the theoretical foundation for this application and how to analyze person fit using BF. To demonstrate the feasibility of this approach,…
