The number of English learners (ELs) who do not reclassify as English proficient after the first five years of schooling has increased in the Houston area and the state of Texas. ELs are a diverse population of students with varying levels of English proficiency. Many students who begin school as an EL reclassify as English proficient in a timely…

The current study evaluated whether goal-setting practices that account for seasonal developmental patterns of reading growth decreased the number of weeks data needed to be collected in order to yield accurate response to intervention decisions for a sample of 224 third-grade students. The extent to which more complex decision-making practices…

Delayed feedback during categorization training has been hypothesized to differentially affect 2 systems that underlie learning for rule-based (RB) or information-integration (II) structures. We tested an alternative possibility: that II learning requires more precise item representations than RB learning, and so is harmed more by a delay interval…

The Big Data for Education Spoke of the NSF Northeast Big Data Innovation Hub and ETS co-sponsored an educational data mining competition in which contestants were asked to predict efficient time use on the NAEP 8th grade mathematics computer-based assessment, based on the log file of a student's actions on a prior portion of the assessment. In…

Reclassification is a crucial outcome for English learner (EL) students' academic progress. Though ELs spend a large portion of their academic time with general education teachers, we know little about the role general education teachers play in developing ELs' English language proficiency. Drawing from a longitudinal administrative dataset from…

This report summarizes findings from a 2016 study that estimated the time it takes English learner students to be reclassified as former English learner students in seven Washington state school districts. The study found that it took students who entered kindergarten as English learner students a median of 3.8 years to develop the English…

How long does it typically take English learner students to develop English language proficiency? And how does this time vary by student characteristics such as English proficiency at entry to kindergarten, gender, and home language? The answers to these questions can provide valuable information to districts and schools. Regional Educational…

This study uses 9 years of longitudinal, student-level data from the Los Angeles Unified School District to provide updated, empirically-based estimates of the time necessary for English learners (ELs) to become reclassified as proficient in English, as well as factors associated with variation in time to reclassification. To illustrate how…

We examined how feedback delay and stimulus offset timing affected declarative, rule-based and procedural, information-integration category-learning. We predicted that small feedback delays of several hundred milliseconds would lead to the best information-integration learning based on a highly regarded neurobiological model of learning in the…

Two studies investigated the effectiveness of dynamic and static visualizations for a perceptual learning task (locomotion pattern classification). In Study 1, seventy-five students viewed either dynamic, static-sequential, or static-simultaneous visualizations. For tasks of intermediate difficulty, dynamic visualizations led to better…

How does variability between members of a category influence infants' category learning? We explore the impact of the order in which different items are sampled on category formation. Two groups of 10-months-olds were presented with a series of exemplars to be organized into a single category. In a low distance group, the order of presentation…

The present study was commissioned by the Massachusetts Department of Elementary and Secondary Education (ESE) to provide a profile of Massachusetts English Language Learners (ELLs) and policy recommendations for improving their outcomes. ESE was concerned about previous study findings that most of these learners exited ELL instructional programs…

This brief describes findings on the percentage of English learner students entering school in kindergarten in seven Washington school districts who developed the English proficiency necessary to be reclassified as former English learner students and the average time to reclassification. Eighty-five percent of English learner students who entered…

The aim of the present study was to explore the spatial organization of auditory time and the effects of the manipulation of spatial attention on such a representation. In two experiments, we asked 28 adults to classify the duration of auditory stimuli as "short" or "long". Stimuli were tones of high or low pitch, delivered left or right of the…

Previous studies have found a late frontal-central audiovisual interaction during the time period about 150-220 ms post-stimulus. However, it is unclear to which process is this audiovisual interaction related: to processing of acoustical features or to classification of stimuli? To investigate this question, event-related potentials were recorded…
