It is my hope that research and analysis on the subject of 'teacher  cognition' can provide insights to improve teacher education and  development. Here are some suggested readings to get started.

Intro (except):
I  cannot count the number of times a graduate student or colleague has  asked me for an article or book that provides an overview of the  research on language teacher cognition. In fact, these sorts of requests  have been so common in recent years that I even toyed with the idea of  writing such a book myself. Thank goodness Simon Borg has finally  written that book. In Teacher Cognition and Language Education: Research  and Practice, Borg provides a comprehensive overview of the research to  date on what language teachers think, know and believe and the complex  relationship to their instructional practices. In doing so he brings a  greater sense of unity and coherence to a somewhat disparate body of  research that has focused on “the complex, practically-oriented,  personalized, and context-sensitive networks of knowledge, thoughts, and  beliefs that language teachers draw on in their work” (p. 272).

Intro (excerpt):
Over  the past decade, applied linguistics research focusing on language  teachers has shown that what teachers do in the classroom is  inextricably linked to what they know, think and believe. As a result,  recent investigations on language teachers and teacher education have  moved away from focusing exclusively on teachers’ observable behaviours  and towards exploring the links between their mental processes and their  classroom practices. An impressive and ever-growing volume of studies  has been published on the subject with numerous cognitive constructs  investigated, ranging from teachers’ knowledge, beliefs and conceptions  to their images, perceptions, maxims and personal theories. Because of  this variety, it can be a rather overwhelming experience to try and make  sense of the results and to find one’s way around this rather  perplexing domain of inquiry. Simon Borg fully recognises the  fragmentation of the field, so the overview he offers in this book comes  as a much needed ‘spring-cleaning’ project. Not only does he manage to  fulfil his aim to “impose some structure on this field” (p. 280), but  what the reader ends up with as a result of Borg’s meticulous  re-organising, untangling and de-cluttering is a clearly-marked and  easy-to-navigate map of the language teacher cognition territory.
The  text is divided into two main parts, the first dedicated to conceptual  issues while the second part surveys and critically appraises the  methodological options available to researchers in this domain. In the  introductory chapter of the conceptual part, Borg provides a detailed  historical overview of the development of the field in both the  mainstream education and language teacher education literature, followed  by a list of key readings. He categorises studies in language teacher  cognition into four types (each covered by one chapter), the first two  exploring cognitions of pre-service and in-service teachers,  respectively, and the latter two investigating teachers’ cognitions in  relation to specific curricular areas, namely grammar and literacy.  Borg’s classification system works well and, along with compact  summaries throughout the book and highly useful thematic tables  describing lists of studies, the coverage fulfils its purpose and does  the field justice.

Abstract:
Language  teacher cognition research is a growing field. In recent years  several  features of language teacher cognitions have been noted: they  can be  complex, ranging over a number of different subjects; they can be   dynamic, changing over time and under different influences; and they   can be systems, forming unified and cohesive personal or practical   theories. However, as yet there is no single theoretical framework for   studying language teacher cognitions. In this article I propose that   complex systems theory might offer such a framework. I offer an   exploratory investigation of the applicability of complex systems theory   by focusing on the re-analysis of a previously published case study of   the practical theory of an English language teacher teaching EFL in   Armenia. I do this by discussing and presenting evidence of   heterogeneity, dynamics, non-linearity, openness, and adaptation, which   characterize complex systems, and are displayed by the EFL teacher's   cognitions. I conclude by suggesting that complex systems theory is   compatible with other lines of research, is able to be developed in   field-specific ways, offers several lines of research as well as   different methodological approaches, and has practical implications for   language teacher development.
