Practicing clinicians frequently offer judgments about aspects of swallowing physiology rather than performing actual measurements. Little is known about the accuracy of those judgments. The purpose of this preliminary study was to explore agreement of clinicians' judgments of pharyngeal swallow response time (PSRT) with temporal measurements of…

The 12th iteration of the International Conference on Educational Data Mining (EDM 2019) is organized under the auspices of the International Educational Data Mining Society in Montreal, Canada. The theme of this year's conference is EDM in Open-Ended Domains. As EDM has matured it has increasingly been applied to open-ended and ill-defined tasks…

According to Keller's Model of Motivation, one technique for increasing learners' motivation, and thus their mental effort, involves increasing the personal relevance of the material. When instruction is perceived as relevant, learners perceive that important personal needs are being met by the learning situation. The purpose of this study was to…

This report describes a simulation of adults' retrieval of arithmetic facts from a network-based memory representation. The goals of the simulation project are to: demonstrate in specific form the nature of a spreading activation model of mental arithmetic; account for three important reaction time effects observed in laboratory investigations;…

A study evaluated the validity of the use of digital dexterity and reaction time as variables to predict students' gross typing speed. To gather data for the study, researchers tested approximately 120 students from three typing classes at Jefferson Community College in Louisiana and one typing class at the University of Louisville (Kentucky). In…

To determine whether children's knowledge of arithmetic facts becomes increasingly "automatic" with age, 7-year-olds, 11-year-olds, and adults were given a number-matching task for which mental arithmetic should have been irrelevant. Specifically, students were required to verify the presence of a probe number in a previously presented pair (e.g.,…

In a study of the relationship between speed of information processing and general intelligence, vocational college students (50 black males and 56 white males) took eight different reaction time tests measuring the speed with which individuals perform various elementary cognitive processes, and a group test of scholastic aptitude (the Armed…

The use of time in school, specifically the portion of time defined as active responding time, has been shown to correlate significantly with achievement. The comprehensive observational methodology of the academic engaged time studies provides the basis for systematically investigating student responding time and elements of the educational…

A computer model of memory (based on input, retrieval, and reaction time) was applied to the rapid processing of simple arithmetic facts (addition, subtraction, and multiplication) by 18 educable retarded adolescents when compared with 18 nonretarded fourth graders (of equal mental age) and 18 normal adolescents. Results for addition indicated…

A three-year longitudinal study was conducted with 895 Head Start children to examine the development of self-regulatory abilities during the preschool years. The purpose was to discover, given the behaviors measured, whether there is convergent and discriminant validity for the existence of one or more dimensions of self requlatory behaviors…

The model described in this paper for the teaching of beginning shorthand through the use of computer-assisted instruction attempted to prevent incorrect responses from occurring during the acquisition of correct responses to beginning shorthand symbols. (Author)

Sixth- and seventh-grade teachers were trained to maintain an average teacher wait time of three to five seconds during mathematics and language arts lessons. Longer waits were associated with higher achievement, improved teacher and student discourse, and greater time spent in cognitive processing. (GDC)

In response to a request from the North Carolina Division of Social Services (DSS), Center for Child and Family Policy at The Terry Sanford Institute at Duke University evaluated the Multiple Response System reform for families reported for child maltreatment. The North Carolina State Legislature has mandated the evaluation of five key aspects of…

Groups of mentally retarded subjects matched for sex, chronological age, mental age, and length of institutionalization were observed on three reaction time tasks for which pre-response complexity varied. Down's Syndrome subjects did not differ from epileptic and undifferentiated retarded subjects in reaction time performance on any of the tasks.…

When Chinese adults tried to name the color of characters which represented conflicting color words, they showed greater interference than did English speaking readers of the same task in English. This effect cannot be attributed to bilingualism. There may be fundamental differences in the perceptual demands of reading Chinese and English.…
