Good practice for pupils learning English as an additional language; lessons from effective literacy teachers in inner city primary schools.

This article presents observations and discussion of the successful teaching of English to pupils, in English primary schools, for whom English is an additional language (EAL). It draws on research in Year 2 (6/7year old) classes in three inner-city primary schools carried out in 2003 and 2005. Three recognised, effective teachers of literacy were selected for case study; all worked in successful schools where results for literacy, measured by national tests, were in line with or better than national averages. Following analyses of lesson observations and interviews with the teachers, their Headteachers and the EAL co-ordinators in the schools, a number of common elements in their practice emerged. Discussion centres on how these pedagogical features supported effective learning environments for the early literacy development of bilingual children, and on the implications for the practice of teaching English to all pupils.

Endothelin-1 promotes phosphorylation of CREB transcription factor in primary cultures of neonatal rat cardiac myocytes: implications for the regulation of c-jun expression.

Cardiac myocyte hypertrophy is associated with an increase in expression of immediate early genes (e.g. c-jun) via activation of pre-existing transcription factors. The activity of CREB transcription factor is regulated through phosphorylation of Ser-133 by one of several protein kinases (e.g. protein kinase A (PKA), p90 ribosomal S6 kinases (RSKs) and the related kinase, MSK1). A cell-permeable form of cAMP, hypertrophic agonists (endothelin-1 (ET-1), phenylephrine (PE)) and hyperosmotic shock all promoted phosphorylation of CREB(Ser-133) in rat neonatal cardiac myocytes. The response to endothelin-1 required the extracellular signal-regulated kinase cascade which stimulates both RSKs and MSK1. Phosphorylation of CREB(Ser-133) in response to ET-1 was not associated with any increase in DNA binding to a consensus cAMP-response element (CRE). The rat c-jun promoter contains elements which may bind either c-Jun/ATF2 or CREB/ATF1 dimers. Using extracts from rat cardiac myocytes, we identified at least two complexes which bind to the most proximal of these elements, one of which contained CREB and the other c-Jun. Thus, phosphorylation and activation of CREB in cardiac myocytes may be effected by a range of different stimuli to influence the expression of immediate early genes such as c-jun.
