Clinical outcomes of treatment with idebenone in Leber's hereditary optic neuropathy in the Netherlands:A national cohort study
Purpose The purpose of the study was to present results from a national Dutch cohort of patients with Leber's Hereditary Optic Neuropathy (LHON) treated with idebenone. Methods The multicentre, open-label, retrospective evaluation of the long-term outcome of idebenone treatment of Dutch LHON patients on visual function and on thickness of the retinal ganglion cell layer. Patients included in the analysis had a confirmed mutation in their mitochondrial DNA encoding either of the seven subunits of complex I, had a reported loss of vision in at least one eye and had a follow-up of more than 6 months after their treatment was started. Control visits involved routine clinical examinations of visual function and retinal structure at (1) the start of treatment, (2) nadir (time of lowest visual acuity), (3) the time of recovery (if any), (4) the time of termination of treatment and (5) more than 6 months after termination of the treatment. Results Data from 72 patients were analysed. Treatment duration was 23.8 +/- 14.4 (mean +/- SD) months. A positive response, that is either a clinically relevant recovery (CRR) or a clinically relevant stabilization (CRS), occurred in 53% and 11% of the patients, respectively. The magnitude of CRR was 0.41 +/- 1.54 logMAR. CRR of visual acuity is associated with recovery of colour discrimination. The thickness of both the ganglion cell complex (GCC) and the retinal nerve fibre layer (RNFL) is irreversibly reduced. Conclusion Our results confirm that idebenone may help to restore or maintain visual function. Whether this effect will persist is still unknown. Thinning of retinal neural tissue appears to be permanent
To what extent is behaviour a problem in English schools?:Exploring the scale and prevalence of deficits in classroom climate
The working atmosphere in the classroom is an important variable in the process of education in schools, with several studies suggesting that classroom climate is an important influence on pupil attainment. There are wide differences in the extent to which classroom climate is considered to be a problem in English schools. Some ‘official’ reports suggest that behaviour in schools is ‘satisfactory or better’ in the vast majority of schools; other sources have pointed to behaviour being a serious and widespread problem. The paper details four studies conducted over the past decade which aimed to explore these disparities. The aim of the research was to gain a more accurate insight into the extent to which deficits in classroom climate limit educational attainment and equality of educational opportunity in English schools. The findings question the suggestion that behaviour is satisfactory or better in 99.7% of English schools and the concluding section suggests ways in which deficits in classroom climate might be addressed. Although the study is limited to classrooms in England, OECD studies suggest that deficits in the working atmosphere in classrooms occur in many countries. The study therefore has potential relevance for education systems in other countries
Swimming against the tide: A case study of an integrated social studies department
A recent trend in developed countries’ school curricula has been the transition from disciplinary to generic forms of knowledge, resulting in an emphasis on interdisciplinary organisation and more active forms of learning. Subject specialists are increasingly expected to demonstrate how their subject interconnects and equips pupils with key life skills. Such a change requires a major cultural shift and has been controversial, particularly in Scotland where Curriculum for Excellence, the latest curriculum reform, has seen this debate re-emerge. A detailed empirical case study of one secondary school Social Studies department that has already negotiated these shifts is presented. The case study provides insights into how school and department structures and cultures conducive to a more integrated approach have been developed. Leadership, increased opportunities for teachers to exercise greater autonomy in their work, sources of impetus and support for innovation, and the co-construction of meaning through dialogue are important themes in this process. This case study connects with current policy and provides an insight into strategies that other schools might employ when seeking to embed integrative practices. The department is identified as a significant locus for innovation and one which appears to challenge the norm
Successful learning: balancing self-regulation with instructional planning
Many recent studies have stressed the importance of teacher
candidates’ (TCs) self-regulated learning (SRL) skills for successful
learning. Because of the promising consequences of SRL for
academic performance, teacher educators (TEs) are encouraged to
increase TCs’ SRL opportunities in educational programs. Because
of the difficulty and complexity for TEs to successfully guide TCs
towards SRL, the present study contributes to the discussion how
to best facilitate TEs in finding a balance between student- and
teacher-control. For this purpose, a conceptual model is presented.
The model draws upon literature related to the perspective of the
learner, the teacher and the learning task. Besides the context of
teacher education, the model is beneficial for higher education as
well as teaching and teacher professionalization. It will help
instructors provide a more balanced approach between teacherand
student-controlled learning, and support students develop
essential SRL skills
Californian Science Students' Perceptions of their Classoom Learning Environments.
This study utilised the What Is Happening In this Class (WIHIC) questionnaire to examine factors that influence Californian student perceptions of their learning environment. Data were collected from 665 USA middle school science students in 11 Californian schools. Several background variables were included in the study to investigate their effects on students’ perceptions, such as student and teacher gender, student ethnic background and socio-economic status (SES), and student age. Class and school variables, such as class ethnic composition, class size and school socioeconomic status were also collected. A hierarchical analysis of variance was conducted to investigate separate and joint effects of these variables. Results from this study indicate that some scales of the WIHIC are more inclined to measure personal or idiosyncratic features of student perceptions of their learning environment whereas other scales contain more variance at the class level. Also, it was found that different variables affect different scale scores. A variable that consistently affected students' perceptions, regardless of the element of interest in the learning environment was student gender. Generally speaking girls perceived their learning environment more positively than did boys
Field-study science classrooms as positive and enjoyable learning environments
We investigated differences between field-study classrooms and traditional science classrooms in terms of the learning environment and students’ attitudes to science, as well as the differential effectiveness of field-study classrooms for students differing in sex and English proficiency. A modified version of selected scales from the What Is Happening In this Class? questionnaire was used to assess the learning environment, whereas students’ attitudes were assessed with a shortened version of a scale from the Test of Science Related Attitudes. A sample of 765 grade 5 students from 17 schools responded to the learning environment and attitude scales in terms of both their traditional science classrooms and classrooms at a field-study centre in Florida. Large effect sizes supported the effectiveness of the field-studies classroom in terms of both the learning environment and student attitudes. Relative to the home school science class, the field-study class was considerably more effective for students with limited English proficiency than for native English speakers
Learning environments research in English classrooms
Although learning environments research has thrived for decades in many countries and school subjects, English classroom environment research is still in its infancy. This article paves the way for expanding research on English classroom environments by (1) reviewing the limited past research in English classrooms and (2) reporting the first study of English learning environments in Singaporean primary schools. For a sample of 441 grade 6 students, past research in other subjects was replicated in that a modified version of the What Is Happening In this Class? questionnaire was cross-validated, classroom environment was found to vary with the determinants of student sex and ethnicity, and associations emerged between students’ attitudes and the nature of the classroom environment
Schools, teachers, and curriculum change: A balancing act?
Educational change is a fact of life for teachers across the world, as schools are subjected to constant and ubiquitous pressures to innovate. And, yet, many school practices remain remarkably persistent in the face of such innovation. This paradox of innovation without change is perplexing for policymakers and practitioners alike. This paper investigates the gap between policy and practice, between innovation and the changes in social practices that occur in response to such innovation. It draws upon empirical data from two case studies in Scotland — schools responding to new curriculum policy—exploring contrasting approaches to the management of innovation. One is a laissez faire approach, and the other a more directive managerial strategy. Through an analytical separation of culture, structure, and agency, derived from the social theory of Margaret Archer, the paper sheds light on the social processes that accompanied innovation in these two settings demonstrating how teacher culture and differing management styles impact upon externally initiated policy
The Influence of Education and Socialization on Radicalization: An Exploration of Theoretical Presumptions and Empirical Research
Background and Objective: Research into radicalization does not pay much attention to education. This is remarkable and possibly misses an important influence on the process of radicalization. Therefore this article sets out to explore the relation between education on the one hand and the onset or prevention of radicalization on the other hand. Method: This article is a theoretical literature review. It has analyzed empirical studies-mainly from European countries-about the educational aims, content and style of Muslim parents and parents with (extreme) right-wing sympathies. Results: Research examining similarity in right-wing sympathies between parents and children yields mixed results, but studies among adolescents point to a significant concordance. Research also showed that authoritarian parenting may play a significant role. Similar research among Muslim families was not found. While raising children with distrust and an authoritarian style are prevalent, the impact on adolescents has not been investigated. The empirical literature we reviewed does not give sufficient evidence to conclude that democratic ideal in and an authoritative style of education are conducive to the development of a democratic attitude. Conclusion: There is a knowledge gap with regard to the influence of education on the onset or the prevention of radicalization. Schools and families are underappreciated sources of informal social control and social capital and therefore the gap should be closed. If there is a better understanding of the effect of education, policy as well as interventions can be developed to assist parents and teachers in preventing radicalization. © 2011 The Author(s)
A diversidade em sala de aula e a relação professor-aluno
O presente estudo teve como objetivo identificar as percepções de professores quanto à relação professor-aluno, a partir da aplicação da Escala de Relacionamento Professor-Aluno, versão reduzida e traduzida da Student-Teacher Relationship Scale, relacionando seus domínios a características dos discentes, no que tange às variáveis necessidade educacional especial, sexo, cor/raça, série e idade. Na pesquisa, 21 professoras regentes de seis escolas públicas da cidade de Juiz de Fora, no estado de Minas Gerais, avaliaram a relação que mantêm com todos os discentes de suas turmas, perfazendo um total de 495 escalas referentes a estudantes de salas-alvo, do primeiro ao quinto ano do Ensino Fundamental. Constatou-se que a relação professor-aluno é mais conflituosa e menos positiva quando se trata de discentes do sexo masculino e com necessidade educacional especial. Observou-se uma relação mais positiva com estudantes nos anos iniciais de escolarização, e mais negativa quanto mais velho fosse o aluno. Estudos adicionais são recomendados
