Dyslexia assessment in Arabic

Despite advancements in empirical studies of developmental dyslexia, progress on methods of dyslexia assessment have been hampered by ongoing debate concerning diverse issues such as the role and validity of IQ in the assessment process, labelling and definitions ( Miles, 1994 ; Stanovich, 1991, 1992 ). With the emergence of cross-linguistic studies of dyslexia came the realisation that the manifestation of dyslexia is different in different languages ( Goulandris, 2003 ; Smythe, Everatt & Salter, 2004 ). It follows that the assessment of dyslexia should consider specific linguistic features of the language spoken by the individual to be assessed. This paper argues for the need of culture-fair assessment and calls for considerations to be given when assessing monolingual Arabic-speaking individuals with dyslexia which would take into account the specific linguistic feature of the Arabic language.     

When Classrooms Matter: implications of between‐classroom variability for educational policy in Israel

This study assesses several policy implications of within‐school, between‐classroom variability in pupil achievement. It diverges from current school effect studies by directly modelling pupil achievement in the Jerusalem public primary school system. This three‐level study includes pupils, classrooms and schools, thus allowing an appropriate estimate of the variations between these three levels. The findings show that between‐classroom variability is consistently greater than the estimated variation between schools. These findings contrast with traditional school‐level analyses that usually ignore within‐school variability. In the light of these findings we address three educational and policy issues. First, we probe into the moral consequences of between‐classroom, within‐school variability, specifically focusing on issues of choice and commitment. Second, we scrutinize the administrative policy of ‘social integration’ and reflect on some educational consequences that result from our findings. Third, we assess the Israeli version of ‘school league tables’ and discuss their usefulness as a means of resource allocation     

Literacy ability and phonological processing skills amongst dyslexic and non-dyslexic speakers of Arabic

This paper investigates the relationship between phonological processing and reading ability amongst grade 4 and grade 5 Arabic speaking children in Egypt. In addition to measuring reading level, the study assessed the children’s ability to identify rhymes, delete individual phonemes from words, retain and manipulate sequences of digit names and rapidly access verbal labels. Further literacy and literacy-related tasks required children to decode novel letter strings, to distinguish similar words, to identify words within letter chains and to correctly spell dictated text. A non-verbal ability measure was also included to allow comparisons to be made between a group of poor readers with good non-verbal skills (dyslexics) with a control group of chronological-age-matched normal readers with equivalent average scores on the non-verbal task. Results indicated relationships between literacy ability, decoding and phonological processing within this cohort, as well as identifying differences between dyslexic and control groups that suggest Arabic dyslexics show signs of poor phonological skills. The study supports the view that Arabic dyslexic children have impairments in the phonological processing domain.

Raman crystal lasers in the visible and near-infrared

Raman lasers based on potassium gadolinium tungstate and lead tungstate crystals pumped bya≈120 ps Nd: YAG laser at 1.064 μm were developed. High reflection mirrors for the Stokes wavelength have been used to generate near-infrared and eye safe spectral region of 1.15–1.32 μm. Second harmonic generation of the generated Raman lasers was observed. Eifficient multiple Stokes and anti-Stokes picosecond generation in 64 crystals have been shown to exhibit stimulated Raman scattering on about 700 lines covering the whole visible and near-infrared spectrum. All stimulated Raman scattering (SRS) wavelengths in the visible and near-infrared spectrum are identified and attributed to the SRS-active vibration modes of these crystals.     

School Organization and Market Ecology: a realist sociological look at the infrastructure of school choice

Programs of school choice are based largely on the idea of a free market’. Recent reform efforts have been based on the assumption that market‐driven educational systems would bring higher achievement levels and greater satisfaction among clients. According to popular views, parents would shop for a school just as they do for any other commodity and competition between schools would ensue, with each school trying to improve itself thereby attracting consumers. There is a major drawback to this reasoning. Markets are rarely completely free from regulation and control, and the desires of individuals do not fully explain the social facts of school choice. As a complement to current school choice studies, a structural explanation of school choice within the theory of network analysis is presented. The study analyses choice in terms of inter‐school student transfers and explains choice as the combined result of two factors. The first is the organization of student mobility in schools, in terms of vacant positions (timing and volume) and student body composition, which posits nine ideal types of school organization. The second factor is the ecology of the market, given in the number of schools in each type. Research conducted in a large city in Israel serves as an example for the approach. The more general implications of the study suggest directions for the theoretical refinement of mobility and attainment studies in sociology.     

Can we administer the scholarship of teaching? Lessons from outstanding professors in higher education

Boyer’s call for the study of the “scholarship of teaching” has rekindled interest in outstanding teaching in higher education. However, most studies of teaching quality and student experiences in higher education have paid little attention to intense, meaningful key experiences and were limited in answering the pertinent question: Can universities administer excellent instruction? The current paper attempts to answer this question by providing exploratory evidence of key experiences in higher education. It is based on evidence from a large qualitative study of such episodes, using retrospective accounts provided by adults who speak about their best educational experiences in higher education. The results are grouped under three major thematic headings. The first describes the centrality of personalized student–teacher relations. The second focuses on the ways in which identification and integrity provided students with models to emulate; and the third tells of excellence in the skills of teaching. These results point that the administration of the scholarship of teaching is an intricate endeavor.
