Background: Many children with specific language impairment (SLI) in sentence comprehension. These deficits are usually attributed to limitations in the children's understanding of syntax or the lexical items contained in the sentences. This study examines the role that extra-linguistic factors can play in these children's sentence comprehension.…

In simple rule-switching tests, 3- and 4-year-olds can follow each of two sorting rules but sometimes make perseverative errors when switching. Older children make few errors but respond slowly when switching. These age-related changes might reflect the maturation of executive functions (e.g., inhibition). However, they might also reflect…

This study investigates the relationship among (1) college major, (2) knowledge used in reasoning about common health beliefs, and (3) judgment about the accuracy of those beliefs. Seventy-four college students, advanced biology and non-science majors, indicated their agreement or disagreement with commonly believed, but often inaccurate,…

Attending to precision (ATP) is essential in mathematics. This study examined ATP instances through the lens of univocal (functioning to convey information) and dialogic (functioning to generate new meaning) discourse. Analysis of data from five secondary mathematics classrooms focused on whole-class instances of ATP with coding based on the…

We investigated whether students increased their self-assessment accuracy and essay scores over the course of an intervention with a writing strategy intelligent tutoring system, [Writing Pal] (W-Pal). Results indicate that students were able to learn from W-Pal, and that the combination of strategy instruction, game-based practice, and holistic…

The efficacy of animated data visualizations in comparison with static data visualizations is still inconclusive. Some researches resulted that the failure to find out the benefits of animations may relate to the way how they are constructed and perceived. In this paper, we present visual analytics (VA) tool which makes use of enhanced animated…

Archived transcripts from tens of millions of online human tutoring sessions potentially contain important knowledge about how online tutors help, or fail to help, students learn. However, without ways of automatically analyzing these large corpora, any knowledge in this data will remain buried. One way to approach this issue is to train an…

Young adults in the United States have the highest rate of migration compared with other age groups. The most common reasons for moving among all ages are job, housing, or family related. Many of these moves are made between the ages of 18 to 34, an age group marked by various life course transitions associated with moving. These include getting a…

Component Universe Score Profile analysis (CUSP) is introduced in this paper as a psychometric alternative to multivariate profile analysis. The theoretical foundations of CUSP analysis are reviewed, which include multivariate generalizability theory and constrained principal components analysis. Because CUSP is a combination of generalizability…

Over the years, less attention is given to students' spelling skills compared to other areas of literacy achievement like word reading and passage comprehension in relationship to nonmainstream dialect usage. Considering that English spelling is based on the phonological and morphological structures of Mainstream American English (MAE), it is…

In line with the frontal hypothesis of aging, the ability to plan ahead undergoes substantial change during normal aging. Although impairments on the Tower of London planning task were reported earlier, associations between age-related declines and specific cognitive demands on planning have not been studied. Here we investigated the impact of…

Private speech utterances (PS) from 24 preschool children and 24 adults were obtained under (noninteracting) listener present and listener absent conditions using 2 tasks with an identical structure. Children produced significantly more PS in the listener present condition. Similar results were obtained with adults, albeit with a reduced incidence…

Introduction: This paper aims to determine how appropriate information literacy instruction is for preparing students for these unmediated searches using commercial search engines and the Web. Method. A survey was designed using the 2000 Association of College and Research Libraries literacy competency standards for higher education. Survey…

Purpose: The purpose of this study was to determine listeners' ability to learn talker identity from speech produced with an electrolarynx, explore source and filter differentiation in talker identification, and describe acoustic-phonetic changes associated with electrolarynx use. Method: Healthy adult control listeners learned to identify…

Purpose: This study was designed to examine the relationships among minority dialect use, language ability, and young African American English (AAE)-speaking children's understanding and awareness of Mainstream American English (MAE). Method: Eighty-three 4- to 8-year-old AAE-speaking children participated in 2 experimental tasks. One task…
