In 1998 the Northern Examination and Assessment Board selected the poem ‘Nothing's Changed’ by the South African writer Tatamkhulu Afrika as the last of its ten Poems from Other Cultures and Traditions. Published in the NEAB Anthology (1998), ‘Nothing's Changed’ became a favourite at GCSE for its vivid depiction of apartheid and its effects. This article revisits Tatamkhulu Afrika's poem, situating it in the context of educational policy, the creation of the NEAB Anthology, the poem's initial use by Devon Curriculum Services in the 1990s, and its emergence as an object of national study in Britain. It examines how the poem was read under the conditions of its anthologisation and the pressures of examination, highlighting how specific reading practices typically stumbled on the problems of history, cultural representativeness, and literature's capacity to offer a transparent window onto experience.  相似文献

Several multiple-probe-across-participants design studies were employed to evaluate the effectiveness of a supplemental tutoring intervention using Read Well (Sprick, Howard, & Fidanque, 1998-2000). In Year 1, we conducted two studies with 7 first-, second-, and third-grade children (1 girl and 6 boys), who were classified as having learning disabilities, having attention-deficit disorder, or being English language learners and were identified by their teachers as poor readers. The results of the two studies indicated that 3 of the 5 children who received Read Well instruction showed improvement in passage fluency. Student performance on other measures of reading and comprehension was varied. Differences in student characteristics and in the amount of Read Well instruction received (2 to 7 weeks) seemed to account for the differences in performance. In Year 2, we implemented the same tutoring intervention for a longer duration (up to 16 weeks) and included 5 children in second and third grades (2 girls and 3 boys) with reading difficulties. Two of these children had previously participated in the Year 1 studies. The results indicated growth in reading, spelling, and comprehension for most children. Overall, the findings from Year 1 and 2 studies indicate the benefits of increased instructional intensity and duration for children who struggle with emerging reading skills.  相似文献

Oral squamous cell carcinoma is one of the most common malignancies recognized. Biomarkers which can predict presence of cancer and its progression can help in better management of these disorders. Over production of lipid peroxidation byproducts and disturbances in antioxidant defense system have been implicated in the pathogenesis of several diseases including oral cancer. Studies have shown a correlation of butyrylcholinesterase (BChE), with tumourigenesis, cell proliferation and cell differentiation. Earlier we have observed a significant elevation in plasma BChE and protein thiols in oral cancer patients which correlated well with stages of cancer. As it was not clear whether the above markers will be altered in saliva of oral cancer patients this study was undertaken. Institutional Ethics Committee gave permission to carry out this study. Total of 55 subjects comprising healthy controls (n = 30) and biopsy proven oral cancer patients (n = 25) consented to participate in this study. Salivary samples from cases were taken before any definitive treatment. Protein thiols and BChE were estimated in salivary samples using validated assay methods. Oral cancer patients had a significant increase in pre-treatment salivary BChE levels (p ≤ 0.001) and a significant decrease (p ≤ 0.001) in salivary thiols as compared to respective values in controls. Salivary protein thiols and BChE may have a role in pathophysiology of oral cancer. Saliva can be used as a potential non-invasive screening tool in oral cancer patients.  相似文献

The present study evaluated the effectiveness of an instructional intervention (schema-based instruction, SBI) that was designed to meet the diverse needs of middle school students by addressing the research literatures from both special education and mathematics education. Specifically, SBI emphasizes the role of the mathematical structure of problems and also provides students with a heuristic to aid and self-monitor problem solving. Further, SBI addresses well-articulated problem solving strategies and supports flexible use of the strategies based on the problem situation. One hundred forty eight seventh-grade students and their teachers participated in a 10-day intervention on learning to solve ratio and proportion word problems, with classrooms randomly assigned to SBI or a control condition. Results suggested that students in SBI treatment classes outperformed students in control classes on a problem solving measure, both at posttest and on a delayed posttest administered 4 months later. However, the two groups’ performance was comparable on a state standardized mathematics achievement test.  相似文献

This study explored the extent to which domain-specific knowledge predicted proportional word problem-solving performance. We tested 411 seventh-grade students on conceptual and procedural fraction knowledge, conceptual and procedural proportion knowledge, and proportional word problem solving. Multiple regression analyses indicated that all four domain-specific knowledge variables (i.e., conceptual and procedural fraction knowledge, conceptual and procedural proportion knowledge) significantly predicted proportional word problem-solving performance. Conceptual fraction and procedural proportion knowledge contributed the most unique variance (10.0 and 6.7%, respectively, of the total variance) to proportional word problem solving. Procedural fraction and conceptual proportion knowledge each also contributed significant unique variance to proportional word problem solving explaining 5.6 and 2.8%, respectively. The results support the notion that both conceptual fraction and proportion knowledge and procedural fraction and proportion knowledge play a major role in understanding individual differences in proportional word problem-solving performance to inform interventions.  相似文献

ABSTRACT

Access to Malaysian government schools is prohibited for refugee children, and hidden refugee schools only reach a minority of Burmese students in Malaysia. This study used a participatory culture-specific consultation (PCSC) approach to examine the perspectives of Burmese refugee teachers on Burmese refugee student socioemotional issues and classroom management using interviews, observations, a preliminary refugee teacher focus group (N = 10: 4 men, 6 women; M age = 26 years), and a primary focus group with refugee teachers who were Burmese refugees (N = 9: 6 men, 3 women; M age = 30 years). First, themes suggested that societal pressures have an effect on the classroom environment. Second, refugee student behavior and emotions ranged from externalizing to internalizing. Third, refugee teachers relied on traditional Burmese methods for managing serious misbehavior. Fourth, with mild misbehaviors, teachers employed more “modern,” student-centered methods. Results inform culture-specific consultation designed to meet refugee education needs.  相似文献

Alstrom’s syndrome (AS) is a rare autosomal recessive ciliopathic condition affecting 1:10,00,000 children. It’s a single gene disorder of ALMS1 on chromosome 2 with multisystem involvement with cone-rod retinal dystrophy causing juvenile blindness, obesity, insulin resistance, type 2 Diabetes mellitus, hypogonadism and sensorineural hearing loss. Till now only 800 patients with this disorder has been identified so far. In this report, we describe the case of a 9-year old male boy from south India. He had been initially referred for polyphagia, polyuria, polydipsia, generalized weakness from 1 weeks. On examination he was demonstrated features suggestive of AS, including blindness, obesity, type 2 diabetes, altered lipid profile, hypogonadism, acanthosis nigricans, seborrheic dermatitis, right ear discharge and episodes of respiratory tract infections. So, diagnosis of AS is critical as it can easily be overlooked because of the many features associated with metabolic syndrome starting at age 7, a relatively early age.  相似文献

The present study demonstrates the possibility of increased lipid peroxidation and protein oxidation in both maternal and fetal erythrocytes as markers of oxygen radical activity during intrauterine growth retardation. The erythrocyte MDA levels were significantly elevated in mothers of IUGR babies when compared to controls (p<0.01). The endogenous protein damage due to oxidative stress was significantly higher in IUGR mothers when compared to controls (p<0.05). Similarly the proteolytic activity in erythrocyte lysates against oxidatively damaged hemoglobin was significantly increased in mothers of IUGR babies compared to controls (p<0.001). In fetuses born with IUGR, both lipid peroxidation and proteolytic activity were significantly increased when compared to normal newborns (p<0.01). The result of this study indicates that oxidative stress was induced both in IUGR babies and their mothers which is manifested as increased lipid peroxidation and protein oxidant damage.  相似文献
