Analysing the Role of the Teacher in Early Reading: A lesson for researchers

This paper describes two parts of a research study that examined the role of the teacher of reading in the child's first year of school. Traditional research into reading has tended to examine the child's reading behaviour or the methods used by teachers. Research into teacher effectiveness tends to be large scale and uses standardised measures of performance and analysis of task design. This paper argues that teaching, particularly with younger children, is a complex process that cannot be easily defined. The design adopted by researchers will influence findings and, above all, if research into teaching does not involve the teachers themselves, then it is unlikely that new definitions of teaching will arise. The author discusses how the inclusion in the research project of teachers' own perceptions of their role revealed different and contradictory findings to those of more established studies .     

Productive Usability: Fostering Civic Engagement and Creating More Useful Online Spaces for Public Deliberation

This article offers productive usability as a usability approach that focuses on the usefulness of civic Web sites. Although some sites meet traditional usability standards, civic sites might fail to support technical literacy, productive inquiry, collaboration, and a multidimensional perspective—all essential ingredients for citizen-initiated change online. In this article, we map productive usability onto broader philosophies of usability and offer a framework for rethinking usability in civic settings and for teaching productive usability.     

The Promise of Ecological Inquiry in Writing Research

Ecological inquiry (EI) in research of academic and workplace writing explores interactions between individuals and environments as these entities interpenetrate. This article provides a brief history from the past 3 decades of developments in writing theory. It then outlines the key tenets of EI, highlights how EI is compatible with other models, and presents new and interesting possibilities afforded by this type of inquiry.     

Discursive strategies and learning of the school language: an ethnographic study in a classroom with high ethnic and linguistic diversity / Estrategias discursivas y aprendizaje de la lengua escolar: un estudio etnográfico en un aula de alta diversidad étnica y lingüística

Abstract

Research on the dialogic and intersubjective nature of children’s learning has emphasised the study of educational discourse and the semiotic mechanisms involved in understanding the students’ constructive activity. These studies have been carried out in classrooms where there was continuity between the language of instruction and the students’ first language. However, the number of classrooms in which students have an initial language which is not the language of instruction is increasing. This article analyses the educational discourse in a multilingual classroom when the teacher interacts with seven students in a teaching unit about language. The study uses interactional ethnography. The results show the use of teacher inquiry into the students’ beliefs about the task and the semiotic procedures used to construct a shared intersubjective framework. The discussion emphasises the similarity of some of these procedures with those used in the family in the initial stages of language acquisition, as well as the variations which the teacher uses of the social and specific framework of reference.     

Personal inquiry learning trajectories in geography: technological support across contexts

Student engagement in the design and implementation of inquiries is an effective way for them to learn about the inquiry process and the domain being studied. However, inquiry learning in geography can be challenging for teachers and students due to the complexity of scientific inquiry and the diversity of pupils' and teachers' knowledge and abilities. To address this, the Personal Inquiry project has designed a tool kit that includes nQuire, a Web-based tool to support students through the inquiry process. Here, we identify when, across five lessons comprising an inquiry into microclimates, nQuire was used by a teacher and a case study group of her 12 to 13-year-old students, and the ways in which they adopted nQuire as a tool to facilitate the creation of a coherent and cumulative inquiry learning experience over time. We found that students' use of nQuire supported them in capturing and representing their evolving understanding of inquiry, in defining and supporting their progression through the process of inquiry and in resourcing their cognitive engagement in data interpretation and representation. nQuire supported the students in accumulating and integrating new understandings across contexts and over time. In this way, nQuire successfully resourced and supported the students' learning journeys or trajectories. We conclude that nQuire can be an effective tool for supporting teachers' and students' understanding of the nature of inquiry and how to design and implement inquiries of their own.     

Letting experience in at the front door and bringing theory through the back: Exploring the Pedagogical Possibilities of Situated Self-Narration in Teacher Education

As a means of exploring what ‘learning through experience’ in teacher education might look like, situated self-narration is both conceptualized and performed here as the discursive practice through which already familiar and remembered experience may re-presented and re-organized from a forward-looking vantage point. Drawing on poststructuralist views of language and subjectivity and framed by a “pedagogy of possibility” (Simon, 1992 Simon, R. 1992. Teaching against the grain: Texts for a pedagogy of possibility, Westport, CN: Greenwood Publishing Group.  [Google Scholar]), situated self-narration involves three main discursive strategies: interruption, interrogation and interpretation. By way of illustration, I use memory to interrupt my relationship to the dominant narrative of ‘English Teacher as avid reader’ and interrogate my everyday experiences of being a girl as mediated by popular culture, in both cases, drawing on a poststructuralist understanding of identity as an evolving constellation of discursive practices and foregrounding the distinctive qualities of one’s experiences as a possible source of agency. I consider the pedagogical possibilities of such identity work in the context of English teacher education, specifically in terms of teaching theory through the back door (Luke, 1993). I engage what it means to say that the way we “word the world” matters (St. Pierre, 2000 St. Pierre, E. 2000. Poststructural feminism in education: An overview. Qualitative Studies in Education, 13(5): 477–515. [Taylor & Francis Online] , [Google Scholar]) through my own interpreted experience as an evolving yet situated subjectivity; a consciousness-that-teaches.
