How does AI&EdAIED today compare to 25 years ago? This paper addresses this evolution by identifying six trends. The trends are ongoing and will influence learning technologies going forward. First, the physicality of interactions and the physical space of the learner became genuine components of digital education. The frontier between the…

Despite consensus that school absenteeism has negative consequences for children's life outcomes, until recently, little was known about the prevalence of absenteeism or its potential to moderate the impacts of school-based interventions. This study provides evidence from a randomized experiment of a preschool intervention involving 1,876 children…

The study utilized data from the Beginning Postsecondary Students Longitudinal Study (BPS:04/09) to examine factors that affect 4-year college students' likelihoods of completing a science, technology, engineering, or mathematics (STEM) bachelor's degree within 6 years of entering college. Results highlight the lasting influence of high school…

This longitudinal study of 78 Canadian English-speaking students examined the applicability of the stability, cumulative, and compensatory models in reading comprehension development. Archival government-mandated assessments of reading comprehension at Grades 3, 6, and 10, and the Canadian Test of Basic Skills measure of reading comprehension…

Learning from visual representations is enhanced when learners appropriately integrate corresponding visual and verbal information. This study examined the effects of two methods of promoting integration, color coding and labeling, on learning about probabilistic reasoning from a table and text. Undergraduate students (N = 98) were randomly…

This dissertation is comprised of three essays, all of which focus on various impacts of economic recession.

Study abroad can be a life-changing experience, but evidence of its effectiveness is mixed. We examine the experience of studying abroad at colleges in the US and China, which are the largest receiving and sending countries of international students respectively. Using data from two comparable national surveys that follow the same design, we…

High levels of school connectedness have been shown to be associated with positive outcomes for adolescents (e.g., higher levels of self-worth and higher test scores); however, the impact of school connectedness during early adolescence has not been studied in relation to school-related outcomes during later adolescence. The current study explores…

The purpose of this study was to determine the influence, if any; assignment to an inclusive secondary language arts classroom setting has on the academic performance of grade 11 nondisabled general education students in two suburban New Jersey High Schools. Using a sampling process known as Propensity Score Matching (PSM), a statistical technique…

The paper describes a biology tutoring system with adaptive question selection. Questions were selected for presentation to the student based on their utilities, which were estimated from the chance that the student's competence would increase if the questions were asked. Competence was represented by the probability of mastery of a set of biology…

A declining trend in adolescents' interest in science learning and attitudes towards science-related careers has been reported during recent years. There has been a call for more motivating learning environments that inspire students to develop interest towards science. This study examines students' interest development in STEM subjects in an…

School performance pressures apply disproportionately to tested grades and subjects. Using longitudinal administrative data--including achievement data from untested grades--and teacher survey data from a large urban district, we examine schools' responses to those pressures in assigning teachers to high-stakes and low-stakes classrooms. We find…
