Effects of fluency, oral language, and executive function on reading comprehension performance

Reading disability (RD) typically consists of deficits in word reading accuracy and/or reading comprehension. While it is well known that word reading accuracy deficits lead to comprehension deficits (general reading disability, GRD), less is understood about neuropsychological profiles of children who exhibit adequate word reading accuracy but nevertheless develop specific reading comprehension deficits (S-RCD). Establishing the underlying neuropsychological processes associated with different RD types is essential for ultimately understanding core neurobiological bases of reading comprehension. To this end, the present study investigated isolated and contextual word fluency, oral language, and executive function on reading comprehension performance in 56 9- to 14-year-old children [21 typically developing (TD), 18 GRD, and 17 S-RCD]. Results indicated that TD and S-RCD participants read isolated words at a faster rate than participants with GRD; however, both RD groups had contextual word fluency and oral language weaknesses. Additionally, S-RCD participants showed prominent weaknesses in executive function. Implications for understanding the neuropsychological bases for reading comprehension are discussed.

Celebrating Jhumki Basu’s contributions to science education as a scholar and an activist: voices from the field

This metalogue addresses the ways Sreyashi Jhumki Basu mediated our practices in science education and life. We focus on Basu’s uses of critical science agency, democratic science classrooms, and critical feminist ethnography to transform the possibilities for all participants in her research and educational practices. We also examine her use of cases and pedagogical strategies to support youth set practice goals based on conceptions of self and preferred learning trajectories. These strategies allow youth to develop power through the use of disciplinary knowledge and modes of inquiry to support their understanding of themselves as powerful, able to change their position in the world, and make the world more socially just. This (Key Contributors) article acknowledges a life cut short through disease, reflects our personal loss of a friend and colleague, and expresses determination to ensure that her contributions to science education are sustained and continued.

Classroom Management Issues for Teaching Assistants

For many graduate teaching assistants, the task of planning, organizing, motivating, and controlling classroom environments can be overwhelming. Empirical research pertaining to major classroom management problems experienced by TAs is scarce. This article is a report of a survey study regarding TA classroom management at a large, land-grant Research 1 University. The study provides specific information about TAs' perceptions of classroom management experiences and concerns based on TA type, gender, teaching experience, and academic discipline. The results of the study indicate that international and U.S. TAs experienced many common problems, but each of the two types of TAs also had unique problems. More U.S. TAs than international TAs reported experiencing classroom management problems. The years of TA teaching experience were significantly related to the number of classroom management problems and concerns TAs reported. Regression analysis revealed that TA type, teaching experience, and academic discipline, but not gender, were significant predictors of classroom problems and concerns. Discussion of the results, implications, and suggestions for further research are included.     

Embodied cognition as grounding for situatedness and context in mathematics education

In this paper we analyze, from the perspective of 'Embodied Cognition', why learning and cognition are situated and context-dependent. We argue that the nature of situated learning and cognition cannot be fully understood by focusing only on social, cultural and contextual factors. These factors are themselves further situated and made comprehensible by the shared biology and fundamental bodily experiences of human beings. Thus cognition itself is embodied, and the bodily-grounded nature of cognition provides a foundation for social situatedness, entails a reconceptualization of cognition and mathematics itself, and has important consequences for mathematics education. After framing some theoretical notions of embodied cognition in the perspective of modern cognitive science, we analyze a case study – continuity of functions. We use conceptual metaphor theory to show how embodied cognition, while providing grounding for situatedness, also gives fruitful results in analyzing the cognitive difficulties underlying the understanding of continuity. This revised version was published online in July 2006 with corrections to the Cover Date.     

Development of dyslexic subgroups:

There is a consensus that dyslexia is on a continuum with normal reading skill and that dyslexics fall at the low end of the normal range in phonological skills. However, there is still substantial variability in phonological skill among dyslexic children. Recent studies have focused on the high end of the continuum of phonological skills in dyslexics, identifying a “surface” dyslexic, or “delayed” profile in which phonological skills are not out of line with other aspects of word recognition. The present study extended this work to a longitudinal context, and explored differences among subgroups of dyslexics on a battery of component reading skills. Third grade dyslexics (n=72) were classified into two subgroups, phonological dyslexics and delayed dyslexics, based on comparisons to younger normal readers at the same reading level (RL group). The children were tested at two points (in third and fourth grade). The results revealed that the classification of dyslexics produced reliable, stable, and valid groups. About 82 percent of the children remained in the same subgroup category when retested a year later. Phonological dyslexics were lower in phoneme awareness and expressive language. Delayed dyslexics tended to be slower at processing printed letters and words but not at rapid automatic naming of letters, and relied more heavily on phonological recoding in reading for meaning than did phonological dyslexics. A subset of the delayed dyslexics with the traditional “surface dyslexic” pattern (relatively high pseudoword and low exception word reading) was also identified. The surface subgroup resembled the RL group on most measures and was not very stable over one year. The results are discussed in light of current models of dyslexia and recent subgrouping schemes, including the Double-Deficit Hypothesis.     

Case studies of peer assistance for principals

This case study of three different codes of peer assistance for principals was funded by the University of Technology Sydney. Principals from two administrative regions for schooling in NSW were paired according to age, principalship experience and school type, and worked in schools on one of three different modes of peer assistance,viz. peer assistance with facilitator, peer assistance without facilitator, and peer assistance by shadowing. In the first two modes, the principals worked uninterrupted on a negotiated agenda for three days. In the third mode, the principals observed each other’s leadership and management style for two days and provided feedback on the third day. The efficacy of the three models is evaluated and discussed.
