Two member onset consonant clusters with /s/ as the first member (#sC onsets) behave differently from other double onset consonant clusters in English. Phonological explanations of children's consonant cluster production have been posited to predict children's speech acquisition. The aim of this study was to consider the role of the Sonority…

The purpose of the current study is to document phonological change from a multidimensional perspective for a 3-year-old boy with phonological disorder by comparing three measures: (1) accuracy of consonant productions, (2) dynamic assessment, and (3) acoustic analysis. The methods included collecting a sample of the targets /s, [image omitted],…

A theory of attending and reinforcement in conditional discriminations (Nevin, Davison, & Shahan, 2005) is extended to working memory in delayed matching to sample by adding terms for disruption of attending during the retention interval. Like its predecessor, the theory assumes that reinforcers and disruptors affect the independent probabilities…

One of the challenges for educators is composing well-written, specifically stated outcomes of student learning. Developmental teacher training is a program designed to improve the effectiveness of university instructors. The program focuses on improving course methodology by guiding instructors through the development of correctly written and…

[Slides] presented at AERA in Denver, CO in April 2010. This study examined the relationship between students' self-reported high school grade point average (HSGPA) from the SAT Questionnaire and their HSGPA provided by the colleges and universities they attend. The purpose of this research was to offer updated information on the relatedness of…

Being able to use other languages is an essential tool for the modern world. While the image of the world as "a global village" is indeed popular, it does not always correspond to reality. A village would tend to be relatively homogeneous in terms of culture and language. Surely, this monocultural, monolingual picture does not reflect the…

The purpose of this evaluation of Scholastic's "System 44" conducted by RMC Research was to expand the existing research on students with learning disabilities by conducting a randomized study of struggling readers with approximately half of the sample comprised of students with learning disabilities. Specifically, this evaluation…

This is sixth and last in a series of children's novels about the U.S. Civil War. The volume is not intended to be historical narrative of the particular period of the war in which its scenes are laid, the incidents accurately conform to the facts, and especially to the spirit, of the eventful years in which they are placed, as recorded, and as…

To examine the extent to which differences in the initial encoding of information affect preschoolers' vulnerability to suggestion, 4 groups of 4-year-olds (N = 54) individually participated in a simulated shopping event in which they were asked to purchase 6 items from a specially constructed grocery store. Half the children had only 1…

The purpose of the current study was to examine whether log-linear smoothing of observed score distributions in small samples results in more accurate differential item functioning (DIF) estimates under the simultaneous item bias test (SIBTEST) framework. Data from a teacher certification test were analyzed using White candidates in the reference…

Jaw movement patterns were examined longitudinally in a 3-year-old male with childhood apraxia of speech (CAS) and compared with a typically developing control group. The child with CAS was followed for 8 months, until he began accurately and consistently producing the bilabial phonemes /p/, /b/, and /m/. A movement tracking system was used to…

This investigation examined the effects of currently available word prediction software programs that support phonetic/inventive spelling on the quality of journal writing by six students with severe writing and/or spelling difficulties in grades three through six during a month-long summer writing program. A changing conditions single-subject…

Adaptive quadrature is applied to marginal maximum likelihood estimation for item response models with normal ability distributions. Even in one dimension, significant gains in speed and accuracy of computation may be achieved.

The 11th International Conference on Educational Data Mining (EDM 2018) is held under the auspices of the International Educational Data Mining Society at the Templeton Landing in Buffalo, New York. This year's EDM conference was highly competitive, with 145 long and short paper submissions. Of these, 23 were accepted as full papers and 37…

One class of parent-child interaction that has recently received attention is a mother's engagement with her child at a mental level. The current study operationalizes this notion by asking the mothers of 354 7- to 11-year-old children drawn from a larger community sample (N=659) to guess the responses of their children, who, in turn, were asked…
