Validity of self-reported reading disability by parents of reading-disabled and control children     

Sadie N. Decker  George P. Vogler  J. C. Defries 《Reading and writing》1989,1(4):327-331

Composite reading scores obtained from parents of 125 reading-disabled children and 125 matched control children who participated in the Colorado Family Reading Study were used to test the validity of self-reported reading problems. Parents who reported that they encountered serious difficulty learning to read had significantly lower reading scores than did those who reported no positive history of reading problems. Moreover, this difference was larger for parents of reading-disabled children than for those of controls. Thus, parental self-reports provide a valid index of reading problems.  相似文献   

Validation of an integrated experimental set-up for kinetic and kinematic three-dimensional analyses in a training environment     

Boisnoir A  Decker L  Reine B  Natta F 《Sports biomechanics / International Society of Biomechanics in Sports》2007,6(2):215-223

Biomechanical analyses using synchronized tools [electromyography (EMG), motion capture, force sensors, force platform, and digital camera] are classically performed in a laboratory environment that could influence the performance. We present a system for studying the running sprint start that synchronizes motion capture, EMG, and ground reaction force data. To maximize motion capture (Vicon 612 with six cameras), a special dim environment was created in the stadium. "Classical" tools were combined with "purpose-built" tools intended to analyse the different aspects of movement. For example, a synchronization system was built to create a common time-base for all data recordings and a portable EMG system was synchronized by a cable that was "disconnected" by the athlete's movement out of the blocks. This disconnection represented an independent event recorded by different tools. A "gap" was measured for some sprint start events between kinetic and kinematic (motion capture) data. Calibration results, measurements of time "gap", and duration of the independent event were used to validate the accuracy of motion capture and the synchronization system. The results validate the entire experimental set-up and suggest adjustment values for motion capture data. This environment can be used to study other movements and can easily be applied to several sports.  相似文献   

SPECIFIC COGNITIVE PREDICTORS OF EARLY MATH PROBLEM SOLVING     

Scott L. Decker  Alycia M. Roberts 《Psychology in the schools》2015,52(5):477-488

Development of early math skill depends on a prerequisite level of cognitive development. Identification of specific cognitive skills that are important for math development may not only inform instructional approaches but also inform assessment approaches to identifying children with specific learning problems in math. This study investigated the specific cognitive correlates of math problem solving across early grade levels (1–4) while controlling for basic calculation skills. As expected, basic calculation skill was a significant predictor of math problem solving across the entire sample. However, the addition of cognitive measures almost doubled the variance explained (R² = .61). Additionally, only select cognitive variables contributed to the prediction of math problem solving, and these variables change in importance as children develop higher‐level math skills. Results are discussed within a developmental model, which emphasizes the increasing importance of abstract code representations required in higher levels of math performance.  相似文献

Adept through adaptation: Third culture individuals’ interpersonal sensitivity     

Allyn D. Lyttle  Gina G. Barker  Terri Lynn Cornwell 《Int J Intercult Relat》2011,35(5):686-694

This study evaluated the interpersonal sensitivity of third culture individuals, defined as people who lived in a country other than that of their nationality during their developmental years, by comparing them to mono-cultured individuals. While the notion that third culture individuals develop enhanced perceptual skills as a result of intercultural adaptation is widely accepted in popular and professional literature, this assertion has not been empirically tested. Previous research on intercultural communication competence and adaptation has almost exclusively focused on intercultural exposure among adults. This study collected data from 142 individuals using web-based surveys. The instruments measured two aspects of participants’ interpersonal sensitivity: social and emotional sensitivity. Results showed that third culture individuals have significantly higher social sensitivity than mono-cultured individuals, while mono-cultured individuals reported higher emotional sensitivity. Additionally, no significant correlation was found between greater intercultural experience and increased interpersonal sensitivity.  相似文献   

Classroom instructional quality,exposure to mathematics instruction and mathematics achievement in fifth grade     

Erin R. Ottmar  Lauren E. Decker  Claire E. Cameron  Timothy W. Curby  Sara E. Rimm-Kaufman 《Learning Environments Research》2014,17(2):243-262

This study examined the quality of teacher–child interactions and exposure to mathematics instruction as predictors of 5th grade student’s mathematics achievement. The sample was a subset of the children involved in the NICHD–SECC longitudinal study (N = 657). Results indicate that, even after controlling for student demographic characteristics, more exposure to mathematics instruction was related to increased fifth grade mathematics achievement for both calculations and applied problems assessments, but there was no main effect for improved instructional quality. Findings also indicate that, in classrooms where lower instructional quality was observed, greater exposure to mathematics instruction predicted improved mathematics achievement. Findings are discussed in terms of differing aspects of mathematics instruction and the possible compensatory role of exposure to instruction in classrooms of lower quality.  相似文献   

Autism Spectrum Disorders: Neurobiology and current assessment practices     

Ryan A. Allen  Diana L. Robins  Scott L. Decker 《Psychology in the schools》2008,45(10):905-917

This study reviews recent research related to the neurobiology of Autism Spectrum Disorders (ASDs) an provides an empirical analysis of current assessment practices. Data were collected through a survey of 117 school psychologists. The Childhood Autism Rating Scale (CARS), Gilliam Autism Rating Scale (GARS), and Gilliam Asperger's Disorder Scale (GADS) were the most frequently used measures. Among the less popular, but more intensive instruments, the Autism Diagnostic Observation Schedule (ADOS) appears to be gaining popularity within school‐based evaluations. Generally, respondents approached the assessment of ASDs from a traditional psychoeducational perspective and reported the use of a very narrow range of ASD‐specific instruments. Concerns are raised regarding the inconsistent inclusion of developmental questionnaires, parent/guardian interviews, and medical professionals in the ASD evaluation process. Implications for practice and the training of school psychologists are discussed. © 2008 Wiley Periodicals, Inc.  相似文献

The use of reverse engineering to analyse student computer programs     

Philip Vanneste  Koen Bertels  Bart de Decker 《Instructional Science》1996,24(3):197-221

In this paper, an explanatory program understander that can analyse student solutions for programming assignments is described. The approach uses a number of reverse engineering techniques and is grounded on a cognitive model of procedural programming knowledge. It will be shown that, through the use of reverse engineering techniques, a lot of feedback (e.g. on errors) can be generated without having to use any prior knowledge on what the program is supposed to do. When such information is available, problem-specific feedback can also be generated. Furthermore, the use of the cognitive programming concepts allows one to specify the errors in an understandable way using exactly the same words and concepts as human programmers. This opens interesting possibilities for other uses of the proposed program understanding technique described in this article.  相似文献   

Flexible use of lexical and sublexical information in word recognition     

Greg Decker  Greg B. Simpson  Mark Yates  Lawrence Locker 《Journal of Research in Reading》2003,26(3):280-286

Within the dual‐route framework it is hypothesised that readers exhibit flexibility in their use of lexical and non‐lexical information in word naming. In the present study, participants named high‐ and low‐frequency regular one‐syllable English words embedded within lists of regular or irregular one‐ or two‐syllable English words. A large number of irregular words should bias the reader toward the lexical route, whereas a list consisting exclusively of regular words should allow more efficient use of sublexical information present in the word. Word frequency effects were obtained when the list was dominated by either regular or irregular two‐syllable filler words. Furthermore, there was an interaction between frequency and regularity for the one‐syllable words, indicating that the frequency effect was significantly larger when the fillers were one‐syllable irregular words relative to one‐syllable regular words. These results extend those reported for a shallow orthography, and indicate strategic control over the use of phonological and lexical information in English word recognition.  相似文献
