Understanding and analyzing data is a crucial aspect of quantitative literacy in the 21st century, leading scholars and policy makers to push for more rigorous instruction in this area rooted in statistical investigation. In this study, we examine 144 upper-elementary mathematics lessons on data and statistics topics to assess the extent to which…

Clinical Question: When assessing a kindergarten student in the area of early reading skills, does dynamic assessment provide additional classification accuracy over and above static, standardized assessments when determining if the student exhibits a difference in early learning experiences or a true disorder? Method: Systematic Review. Study…

In some computerized educational systems, there is evidence of students "wheel-spinning," where a student tries and repeatedly fails at an educational task for learning a skill. This may be particularly concerning in low resource settings. Prior research has focused on predicting and modeling wheel-spinning, but there has been little…

Accurate placement into an initial college mathematics course is a key step toward the successful completion of college mathematics and, eventually, a college degree. Conversely, misplacement in mathematics may lead to a reduced likelihood of course completion and degree attainment. This study investigated the ability of two placement models to…

Items in the mental lexicon have three storage and processing strata, the concept, lemma, and lexeme, which equate to semantic, syntactic and phonological information. Lexical items relate to each other at each stratum. Bilingual lexicons, which contain items from all languages, may contain cognates, items sharing concepts and with overlapping…

Few studies have examined the impact of alcohol on metacognition for witnessed events. We used a 2 × 2 balanced placebo design, where mock witnesses expected and drank alcohol, did not expect but drank alcohol, did not expect nor drank alcohol, or expected but did not drink alcohol. Participants watched a mock crime in a bar-lab, followed by free…

Purpose: The aims of the study were to determine dual-task effects on content accuracy, delivery speed, and perceived effort during narrative discourse in people with moderate, mild, or no aphasia and to explore subjective reactions to retelling a story with a concurrent task. Method: Two studies (1 quantitative and 1 qualitative) were conducted.…

In most countries, it is not compulsory to be trained to work as an interpreter in community settings. A comparison across jurisdictions reveals that different requirements exist, from a simple self-evaluation of language competence, to passing a certification or accreditation test. Even in countries where certification or accreditation systems…

This study examined whether computerized dynamic testing by utilizing a robot would lead to different patterns in children's (aged 6-9 years) potential for learning and strategy use when solving series-completion tasks. The robot, in a "Wizard of Oz" setting, provided instructions and prompts during dynamic testing. It was found that a…

Purpose: This study examined the relationship between language and planning, a higher order executive function skill, in children with specific language impairment (SLI) and typically developing (TD) children. We hypothesized differences between groups in planning performance and in the role of verbal mediation during planning. Method: Thirty-one…

East Tennessee State University developed a workflow to add journal publications to their institutional repository and faculty profiles using three tools: Zotero for entering metadata, SHERPA/RoMEO for checking copyright permissions, and Unpaywall for locating full-text documents. This study evaluates the availability and accuracy of the…

Background: Acquired apraxia of speech (AOS) involves speech-production deficits on both the segmental and suprasegmental levels. Recent research has identified a non-linear interaction between the metrical structure of bisyllabic words and word-production accuracy in German speakers with AOS, with trochaic words (strong-weak stress) being…

Similar estimation biases appear in a wide range of quantitative judgments, across many tasks and domains. Often, these biases (those that occur, for example, when adults or children indicate remembered locations of objects in bounded spaces) are believed to provide evidence of Bayesian or rational cognitive processing, and are explained in terms…

The literature on calibration suggests that students consider a multitude of factors when they self-evaluate task performance. Nevertheless, few studies have focused on calibration within a complex task environment, such as when students are asked to compose written responses based on multiple texts. In this study, we examined the criteria that…

The authors sought to further the understanding of reading processes and their links to comprehension using two reading tasks for elementary-grade students. One hundred sixty-six students in grades 2-5 were randomly assigned to one of two conditions: reading with questions presented concurrently with text or reading with questions presented after…
