Understanding the ‘Lexia’ in dyslexia: A multidisciplinary team approach to learning disabilities

The historical roots of the IQ-achievement discrepancy definition of learning disability are discussed as a reference point for explaining why this definition came into being and why it is inadequate for dealing with the variety of learning and developmental disabilities that present in school settings. A proposal is offered and justified for defining learning disabilities on the basis of profiles for multiple developmental domains that affect learning. In this proposal, developmental dyslexia is differentiated from other learning disabilities. Developmental dyslexia is defined as uneven development (dissociation) between word reading and higher-level processes in the functional reading system. Dyslexics may struggle with word reading because of deficits in phonological processes, orthographic-phonological connections, and/or fluency (rate, automaticity, or executive coordination). The need for both national and international classification schemes for defining specific learning and developmental disabilities for the purposes of educational services and research is emphasized.

The Strong African American Families Program: translating research into prevention programming

A randomized prevention trial contrasted families who took part in the Strong African American Families Program (SAAF), a preventive intervention for rural African American mothers and their 11-year-olds, with control families. SAAF is based on a contextual model positing that regulated, communicative parenting causes changes in factors protecting youths from early alcohol use and sexual activity. Parenting variables included involvement-vigilance, racial socialization, communication about sex, and clear expectations for alcohol use. Youth protective factors included negative attitudes about early alcohol use and sexual activity, negative images of drinking youths, resistance efficacy, a goal-directed future orientation, and acceptance of parental influence. Intervention-induced changes in parenting mediated the effect of intervention group influences on changes in protective factors over a 7-month period.     

A process model of writing development across the life span

In this article, we provide an overview of writing development from a product perspective and from a process perspective. Then we discuss modifications of the most influential process model of skilled adult writing to explain beginning and developing writing, including a proposed developmental sequence of the emergence of cognitive processes in writing. Next we report the results of two recent dissertations by the second and third authors supervised by the first author aimed toward contrasting developmental issues: (a) specifying the algorithms or rules of thumb beginning and developing writers may use during on-line planning; and (b) investigating the further development of writing processes among skilled adult writers. In the first study, development was conceptualized as a linear process across age groups. In the second study, development was conceptualized as a horizontal process within skilled adult writers who expanded their expertise. Finally, we consider the developmental constraints and the instructional constraints on writing development and argue for a model of writing development in which endogenous and exogenous process variables interact to determine the outcome of the writing development process.     

Women teachers and professional development: gender issues in the training programmes of the Aga Khan Education Service, Northern Areas, Pakistan

In the area of this study, teaching continues to provide the vast majority of formal sector jobs available to women. Within teaching, women's restricted access to training is addressed by AKES, whose programmes appear to meet women's immediate needs for localised training. Nevertheless, women remain largely unrepresented beyond the lowliest levels of the Service. This paper considers why this is so, and explores strategies for facilitating their professional and career development. It stresses the need for a contextualised, gender-aware approach to teacher education, and an avoidance of a simple correlation between girls' and women's education and their broader empowerment.     

Risk factors in early child development: Is prenatal cocaine/poly-drug exposure a key variable?

In order to explore the possible confounding effects of age, race, sex, and socioeconomic status on developmental outcomes of prenatal cocaine exposure, two matched samples of preschoolers (20 children with cocaine/polydrug in utero exposure and 20 children with no prenatal drug exposure) were compared on the Stanford-Binet: 4th ed. (S-B: 4th ed.), Social Skills Rating System, Vineland Adaptive Behavior Scale—Survey Form, Preschool Language Scale: 3rd ed. (PLS: 3rd ed.), and the Child Behavior Checklist. None of the 40 children had attended or were currently enrolled in preschool programs. Both groups had scores approximately one standard deviation below the expected mean in social skills, auditory comprehension, and expressive language. Likewise, externalizing behavior difficulties were approximately one standard deviation above the mean for both groups. Results suggest in utero drug exposure had no independent impact on cognitive, social, language, and behavioral developmental outcomes when the confounding variables of age, ethnicity, gender, and SES were controlled. © 1997 John Wiley & Sons, Inc.     

Work placement experience: should I stay or should I go?

The opportunity to experience work placements that complement taught and practical courses in higher education has become a central strand of many undergraduate degree programmes. While there is tacit agreement that such placements are a good thing, in recent years the numbers of students opting for work placements has been declining. This paper uses a mixed method research design to probe the learning outcomes, attitudes and perceptions of undergraduate students who choose not to go on a work placement. Findings highlight some areas of concern that could be considered by institutions of higher education working to enhance good practice in students’ work placement experiences.     

The Kinematics and Kinetics of the Running Pattern of Two-, Four-, and Six-Year-Old Children

Abstract

Selected kinematic and kinetic variables in the running pattern of 2-, 4-, and 6-year-old children were investigated. Cinematographic records and force-plate tracings were used to study the running patterns of the 28 Caucasian subjects, 15 male and 13 female. A 2 × 3 (sex × age) factorial analysis of variance was used to determine whether effects of variation between and within age and sex factors for each of the dependent variables of selected kinematic (displacement and velocity) and kinetic (ground reaction force) variables were significant. The running speeds improved with age. Although height and weight gains influenced the improvement shown in performance, certain biomechanical variables also contributed to the development of the running pattern. In the majority of the selected kinematic and kinetic variables there were significant differences between the 2-year-old group and the other two groups. Where there were significant differences in the variables, the differences tended to be in displacement, velocity, and magnitude of force measures, rather than in time of occurrence measures. Significant differences between male and female subjects appeared in five kinematic variables related to the swing leg.     

Predicting response to early reading intervention from verbal IQ, reading-related language abilities, attention ratings, and verbal IQ-word reading discrepancy: failure to validate discrepancy method

Additional analyses of a previously published study addressed three questions about growth in word reading during early reading intervention: (1) How well do Verbal IQ, reading-related language abilities (phonological, rapid naming, and orthographic), and attention ratings predict reading growth? (2) How well do language deficits predict reading growth? and (3) How well does Verbal IQ-word reading discrepancy predict reading growth? Univariate analyses showed that Verbal IQ, phonological skills, orthographic skills, rapid automatized naming (RAN), and attention ratings predicted the response to early intervention, but multivariate analyses based on a combination of predictors for real-word reading and pseudoword reading showed that Verbal IQ was not the best unique predictor. Students with double or triple deficits in language skills (RAN, phonological, and orthographic processing) responded more slowly to early intervention than students without language deficits. Verbal IQ-word reading discrepancy did not predict the response to early intervention in reading. Overall results supported the use of reading-related language and attention measures rather than IQ-achievement discrepancy in identifying candidates for early reading intervention.     

Impacts of an Early Childhood Mathematics and Science Intervention on Teaching Practices and Child Outcomes

abstract

This randomized controlled trial examined effects of the MyTeachingPartner-Math/Science intervention on the quality and quantity of teachers’ mathematics and science instruction, and children’s mathematics and science outcomes in 140 pre-kindergarten classrooms. Teachers participated in the intervention for two years with consecutive cohorts of children. Results from Year 1 are considered experimental, however due to high levels of attrition, results from Year 2 are considered quasi-experimental. Across both years, intervention teachers exhibited higher quality and quantity of instruction. In Year 1, there were no significant effects of the intervention on children’s outcomes. In Year 2, children in intervention classrooms made greater gains in teachers’ ratings of mathematics and science skills and performed better on a spring assessment of science skills. These results have implications for designing and evaluating professional development aimed at supporting children’s mathematics and science knowledge and skills.
