Problem Roulette (PR), an online study service at the University of Michigan, offers points-free formative practice to students preparing for examinations in introductory science, technology, engineering, and mathematics courses. Using four years of PR data involving millions of problem attempts by thousands of students, we quantify the benefits…

Machine translation post-editing (MTPE) has become a common practice in translation industry, which calls much attention in academia. However, little research has been carried out to investigate students' cognitive and motivational individual differences in MTPE. The purpose of the present study was to examine the predictive effects of…

Many connectives, such as "therefore" and "however," are used very frequently in the written modality. Their acquisition thus represents an important milestone in developing written language competences. In this article, we assess the development of competence with such connectives by native French speakers in a sentence-level…

In the hours following the 2020 COVID-19 outbreak and subsequent shutdown, educators across the nation were suddenly tasked with teaching online. As Jen Vanek describes in "Supporting Quality Instruction: Building Teacher Capacity as Instructional Designers (Part 1 of 3)" (EJ1344704), the majority of educators had to quickly learn and…

Educational technology is shifting toward facilitating personalized learning. Such personalization, however, requires a detailed understanding of students' problem-solving processes. Sequence analysis (SA) is a promising approach to gaining granular insights into student problem solving; however, existing techniques are difficult to interpret…

How do diagrams and illustrations affect mathematical problem solving? Past research suggests that diagrams should promote correct performance. However, illustrations may provide a supportive context for problem solving, or they may distract students with seductive details. Moreover, effects may not be uniform across student subgroups. This study…

While personality is relatively stable over time, it is also subject to change across the entire lifespan. On a macro-analytical level, empirical research has identified patterns of normative and differential development that are affected by biological and environmental factors, specific life events, and social role investments. On a…

Purpose: Children with autism spectrum disorder (ASD) demonstrate many mechanisms of lexical acquisition that support language in typical development; however, 1 notable exception is the shape bias. The bases of these children's difficulties with the shape bias are not well understood, and the current study explored potential sources of individual…

Atypical visual perception has increasingly been described in individuals with autism spectrum disorders (ASD) and linked to quantitative, autism-like features that are present in children and adults without ASD. We investigated whether individual differences in visual processing skills were related to quantitative measures of autism traits in a…

The present research aimed to determine the circumstances under which comprehension between paper and e-readers is comparable and what role working memory plays in successful comprehension of text presented in these formats. Narrative and expository texts were presented in electronic and paper formats to determine whether readers glean different…

The focus of this study was the ability of adolescents and young adults with Down syndrome to infer meaning from facial expressions in the absence of emotion labels and use this inference in order to adjust their behavior. Participants with Down syndrome (N = 19, mean nonverbal mental age of 5.8 years) and 4- to 7-year-old typically developing…

From a theoretical perspective, most discussions of statistical learning (SL) have focused on the possible "statistical" properties that are the object of learning. Much less attention has been given to defining what "learning" is in the context of "statistical learning." One major difficulty is that SL research has…

Both popular press and academic research laud the benefits of creativity. Malevolent creativity, however, is the application of creativity to intentionally harm others. This study examines predictors of malevolent creativity, considering both contextual and individual difference influences. Social information processing theory suggests that…

Gesture is an integral part of children's communicative repertoire. However, little is known about the neurobiology of speech and gesture integration in the developing brain. We investigated how 8- to 10-year-old children processed gesture that was essential to understanding a set of narratives. We asked whether the functional neuroanatomy of…

Purpose: The purpose of this study is to quantify the interactions of the 3 vocalization subsystems of respiration, phonation, and resonance before, during, and after a perturbation to the larynx (temporarily induced unilateral vocal fold paralysis) in 10 vocally healthy participants. Using dynamic systems theory as a guide, we hypothesized that…
