In the absence of clear incentives, achievement tests may be subject to the effect of slipping where item response functions have upper asymptotes below one. Slipping reduces score precision for higher latent scores and distorts test developers' understandings of item and test information. A multidimensional four-parameter normal ogive model was…

Purpose: Position effects may influence examinees' test performances in several ways and trigger other psychometric issues, such as Differential Item Functioning (DIF) .This study aims to supply test forms in which items in the test are ordered differently, depending on their difficulty level (from easy to difficult or difficult to easy), to…

While it is known that over 500,000 individuals in the State of Indiana have not obtained a High School Diploma or Equivalency (StatsIndiana, 2015), limited empirical information exists on Indiana students pursuing adult basic education along with implications for a state that has changed its adult basic education high stakes high school…

There has been a wealth of research conducted on the high school dropouts spanning several decades. It is estimated that compared with those who complete high school, the average high school dropout costs the economy approximately $250,000 more over his or her lifetime in terms of lower tax contributions, higher reliance on Medicaid and Medicare,…

The purpose of this study was to examine the effects of proactive student-success coaching, informed by predictive analytics, on student academic performance and persistence. Specifically, semester GPA and semester-to-semester student persistence were the investigated outcomes. Uniquely, the community college focused the intervention on only…

Low motivation to perform well on a test is a potentially problematic source of construct-irrelevant variance (Messick, 1980), especially when there are low or no stakes attached to performance. That is, interpretations of test scores as indicators of students' knowledge and skills may be compromised if those students do not put forth the effort…

Facing the increased demand for accountability, colleges and universities nationwide embarked on various initiatives to increase college attainment. One such effort is the Florida state statute, commonly referred to as excess hour surcharge policy, which was implemented at 12 state universities effective July 2009. The Florida legislature intends…

One of the highest ambitions in educational technology is the move towards personalized learning. To this end, computerized adaptive learning (CAL) systems are developed. A popular method to track the development of student ability and item difficulty, in CAL systems, is the Elo Rating System (ERS). The ERS allows for dynamic model parameters by…

Utah's public technical colleges offer vocational certificate programs at a low cost to students, as required by statute. Certificates are accredited by the Council on Occupational Education and provide students with competencies necessary for entry into gainful employment. The ability of students to attain marketable skills at a low cost and in a…

This study examines the relationship between Cycle 1 of the Houston Independent School District (HISD) College Success Initiative and students' preparation for, enrollment in, and persistence in college. Rates of FAFSA submission, two-year applications, four-year applications, and on-time college enrollment all significantly increased during Cycle…

Time dependence is of fundamental importance for the description of quantum systems, but is particularly difficult for students to master. We describe the development and evaluation of a combined simulation-tutorial to support the development of visual understanding of time dependence in quantum mechanics. The associated interactive simulation…

Objective: This study reevaluates the effects of a randomized controlled trial (RCT) of job search interventions on labor force participation. In the trial, various methods of job search interventions were included, of which about half were research-based JOBS (Job Opportunity and Basic Skills) interventions and the other half were practice-based,…

We estimate the percentage of eligible students who do not take up their federal need-based student financial aid entitlements in a microsimulation model for the German Socio-Economic Panel Study 2002--2013. We find that about 40% of the eligible low-income students do not take up their entitlements. Non-take-up is inversely and rather…

This paper studies the effect of exposure to female and male "high-achievers" in high school on the long-run educational outcomes of their peers. Using data from a recent cohort of students in the United States, we identify a causal effect by exploiting quasi-random variation in the exposure of students to peers with highly educated…

The motivating example for this paper comes from a distributed health data network, the International Consortium of Orthopaedic Registries (ICOR), which aims to examine risk factors for orthopedic device failure for registries around the world. Unfortunately, regulatory, privacy, and propriety concerns made sharing of raw data impossible, even if…
