In this paper, I assess labor market returns of a substantial skill upgrade: college enrollment of the vocationally trained, non-traditional students who do not have the formal entry requirement. Using propensity-score-adjusted regressions and the National Educational Panel Study, I find that these enrollees face high opportunity costs as they…

Pre-college student participation in science fairs, robotics competitions, computing contests and other science, technology, engineering, and mathematics (STEM) competitions increases every year in the United States. This is despite the fact that little is known about the relationship between STEM competition participation and career interest in…

The study aimed to develop a typology of victimization based on the extent to which students experienced face-to-face (traditional) victimization and/or cyber-victimization and, consequently, manifested fear and avoidance. The sample consisted of 497 adolescents (ages 12- 18) who took the 2011 School Crime Supplement of the National Crime…

The purpose of this study was to examine the effects of criteria-referenced formative assessment (CRFA) on students' achievement in theater arts. The role of type of task in differentiating the treatment-achievement relationship was explored. The analytical sample included 520 fifth-grade students from 13 schools in New York City. Schools were…

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…

We recorded visual event-related brain potentials from 32 adult male participants (16 high-functioning participants diagnosed with autism spectrum disorder (ASD) and 16 control participants, ranging in age from 18 to 53 years) during a three-stimulus oddball paradigm. Target and non-target stimulus probability was varied across three probability…

How do young children learn about causal structure in an uncertain and variable world? We tested whether they can use observed probabilistic information to solve causal learning problems. In two experiments, 24-month-olds observed an adult produce a probabilistic pattern of causal evidence. The toddlers then were given an opportunity to design…

A behavioral skills training procedure that consisted of video instructions, video rehearsal, and video testing was used to teach 4 recreational gamblers a specific skill in playing blackjack (sometimes called "card counting"). A multiple baseline design was used to evaluate intervention effects on card-counting accuracy and chips won or…

A new probability-based standard setting technique, the Objective Borderline Method (OBM), was introduced recently. This was based on a mathematical model of how test scores relate to student ability. The present study refined the model and tested it using 2500 simulated data-sets. The OBM was feasible to use. On average, the OBM performed well…

Recent literature has underscored the critical role of treatment effect variation in estimating and understanding causal effects. This approach, however, is in contrast to much of the foundational research on causal inference. Linear models, for example, classically rely on constant treatment effect assumptions, or treatment effects defined by…

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…

The article presents an attempt to analyse Monty's dilemma by means of conversational formula-free dialogues and to simulate the problem by composing isomorphic stories. The crucial roles of specifying the underlying scenarios and explicating epistemic and probabilistic assumptions are highlighted.

Since the seminal introduction of the propensity score (PS) by Rosenbaum and Rubin, PS-based methods have been widely used for drawing causal inferences in the behavioral and social sciences. However, the PS approach depends on the ignorability assumption: there are no unobserved confounders once observed covariates are taken into account. For…
