This article is written in response to the article published in issue 39.3 of this journal, in November 2005, on the nature of the Key Stage 2 National Curriculum reading tests: ‘Examining England's National Curriculum assessments: an analysis of the KS2 reading test questions’ by Anne Kispal of the National Foundation for Educational Research. It argues that, far from providing a valid and rewarding assessment experience for pupils as Kispal suggests, the primary English tests at the end of KS2 are invalid as a measuring instrument and are having a damaging effect on pedagogy. The tests and the information on them provided by the Qualifications and Curriculum Agency are based on a misleading unidimensional conception of reading literacy attainment. Because the test assessment simply adds together marks achieved for very different cognitive skills, it propagates a dysfunctional model of literacy pedagogy that conflates and confuses two separate developmental trajectories – word reading and text comprehension. The article goes on to argue that the unidimensionality of the national tests and their pedagogic apparatus has constricted the primary English curriculum in ways that are damaging for young pupils and for the national need for creativity and enterprise. 相似文献

This article describes the development and implementation of a curriculum model that seeks to integrate the study of different types of text in a coherent and meaningful way. An explanation of the rationale behind the model is given and supported by exemplar tasks designed by teachers working within the context of an integrated English, media and drama curriculum. The impact of the model at the end of its first year of operation is evaluated and further areas of development are highlighted. 相似文献

The paper describes the design and implementation of an action research project that set out to raise standards of reading at KS2. Changes to teaching developed by project teachers are outlined, and quantitative and qualitative findings relating to children’s progress are analysed. A particular analysis is made of patterns of teaching in those classes in which boys, as well as girls, made significant progress in their reading. 相似文献

This article concerns the ways in which moving image media enable secondary school students to improve their print literacy standards. It examines productive ways of using moving image media with literary texts to support and enhance the literacy skills of students. It contends that informed use of media enhances students' abilities in critically evaluating, consuming and producing texts and that engaging with print and media texts develops the literacy practices of students. 相似文献

This article considers the pedagogic assumptions of four writers in the post‐war period who have contributed significantly in the UK to the teaching of poetry writing to children (Hughes, 1967; Brownjohn, 1980, 1982 and 1990, collected in 1994; Pirrie, 1987, republished in 1994; Rosen, 1989). This article critiques the approaches of these writers, and the assumptions underlying their practice, in the light of recent writing theory (Bereiter and Scardamalia, 1987; Sharples, 1999), which introduces the concepts of ‘content’ and ‘rhetorical’ space in writing. I argue that current recommendations (DfEE, 1998) are also flawed in that they provide teachers with a limited view of what poetry is, taking little account of the interrelationship between form and content in creating meaning. The article takes the form of an analysis of the intersection of these recommendations and the core literature described above arguing that their differing emphases place teachers at a disadvantage when thinking about pedagogy in this area. 相似文献

This paper reviews changes to the key stage 3 curriculum at a leading comprehensive school. The nature and practical concerns of the changes are described. These move beyond a fresh approach to content; they include issues about engaging students actively in learning for the future, planning around the school's distinctive ethos and expertise in ICT, and using curriculum as a vehicle for providing energy for new staff and heads of department to engage in learning leadership. Theoretical models of curriculum are examined to locate thinking at Brooke Weston CTC in a conceptual framework. The paper suggests that futuristic curriculum development resonates with some classical curriculum models that have been ignored over the past two decades of the National Curriculum. 相似文献

Changes in the teaching of reading during the past decade include a shift away from a previous emphasis on ‘one‐to‐one’ learning experiences to a focus upon more communal forms of learning which place the teacher center stage. With the teacher's role thus highlighted, teacher–pupil interaction in practice has come under the spotlight, with a number of studies raising concerns about the quality of teaching taking place and suggesting this is featuring more traditional patterns of ‘IRF’ exchanges between teachers and pupils, which are limiting to children's learning. This article reports on a small‐scale study into teacher–pupil interaction styles during three Key Stage 1 ‘shared reading’ sessions – an activity in which teacher and children work together on an enlarged, illustrated text, with the teacher explicitly modeling components of the reading process to children. The article considers the more tacit modelling taking place during these sessions and how particular linguistic patterning used by teachers frames reading as an educational and cultural activity in ways that position children differentially in relation to it. In particular, it considers how variation in the use of the IRF exchange can mediate different cultural meanings about what it is to engage with text as a reader. 相似文献

This paper describes a small‐scale writing project in which a class of KS 2 primary pupils were invited to import their own narrative interests into a task designed by their teacher and the researcher within the constraints of the National Literacy Strategy. By employing an adventure genre, based on problem and puzzle solving, pupils were encouraged to introduce familiar scenarios and characters from their favourite stories in books, comics, videos or computer games. The work produced has been analyzed to highlight the different ways in which boys and girls engaged with key aspects of narrative and how this enabled discussion of gendered literacy practices in which boys and girls held an equal stake. The author discusses the importance of developing strategies by means of which children's understanding and transformations of their preferred modes of narrative pleasures can be housed within the current literacy framework. 相似文献

The Year 6 National Curriculum reading test has become a familiar and established annual experience at the end of the primary phase in schools throughout England. From 1993 onwards, each year the national reading test for 11‐year‐olds has consisted of a different set of texts, accompanied by a different set of questions. With over a decade's accumulation of national assessment materials, the National Foundation for Educational Research decided to fund a project to take stock of the reading test, scrutinise what children have been expected to do over the years, and track the evolution of the assessment. A new taxonomy of question focuses, introduced by the Qualifications and Curriculum Authority in 2003 , provided the opportune moment to conduct a retrospective re‐categorisation of all the questions that had ever appeared in a Key Stage 2 reading test. This paper reports on that exercise and reveals that some forms of questioning remain constant and reappear every year, while others are subject to variation. 相似文献

The significance of this article lies in Bob Sproson's willingness to ask difficult questions and to provoke further questions in the mind of the reader. The shift in thinking which allows us to consider 14–19 education as a whole makes the work of support services such as the one described here particularly interesting, with implications far beyond the group of students at KS4 described here as ‘difficult to manage’. As Bob Sproson argues, college placement is no panacea, but requires careful preparation and attention to the needs and views of each student and to the development of mutually respectful relationships between teachers and students. Implied in this article is a radically new view of young people and their educational needs post–14. 相似文献

It is widely assumed that increasing the number of teaching assistants (TAs) in the classroom will be beneficial to children, and this is one important aim of the recently implemented Workforce Agreement. But there are still significant gaps in knowledge about many aspects of their deployment and impact. The Class Size and Pupil—Adult Ratios (CSPAR) KS2 study built on earlier findings when the pupils were in reception and Key Stage (KS) 1, and investigated: (1) the deployment of TAs in classrooms and how key parties involved perceived this; and (2) the effect of TAs on interactions involving pupils and teachers in the same classrooms, and on pupil attainments. The study had a longitudinal, mixed method and multi‐informant design. Methods of data collection included: (for the whole sample) questionnaires completed by TAs, teachers and head teachers, assessments of pupil attainments in mathematics, English and science, data on pupil background, and (for a sub‐sample) case studies and a systematic observation study. This study found that the TA's role in KS2 is predominantly a direct one, in the sense of face‐to‐face interactions supporting certain pupils. There was no evidence that the presence of TAs, or any characteristic of TAs, had a measurable effect on pupil attainment. However, results were clear in showing that TAs had an indirect effect on teaching, e.g. pupils had a more active form of interaction with the teacher and there was more individualised teacher attention. This supported teachers' views that TAs are effective in supporting them in this way. The authors conclude that more attention needs to be paid to what they call the pedagogical role of TAs so that they can be used effectively to help teachers and pupils, particularly in the context of the enhanced roles for TAs being introduced as part of the Government's remodelling agenda. 相似文献
