This book introduces six general procedures for teaching grammar to learners of English as a second language. The procedures are designed to encourage learners to notice, explore and practice grammar in context. Each description and discussion of a procedure is followed by two sample lesson plans together with sample texts and worksheets. Teachers can either use these 'as is' or adapt them for their own students. The lessons are suitable for a wide range of students from beginning learners to advanced learners. A final chapter provides examples of lessons in which several procedures are combined. In addition, before each sample lesson plan, the grammar focus of the lesson is briefly explained for the teacher. These procedures all illustrate how grammar can be taught through texts, and they are based on an understanding of the latest research on pedagogical grammar and the role of language awareness and discovery in second language learning and provide teachers with principles they can apply in developing their own teaching materials and activities. The grammar explanations preceding each teaching plan provide a fresh look at English grammar drawing on work in systemic functional linguistics.

This study evaluates the differing claims of the Aspect Hypothesis (Anderson & Shirai 1996) and the Sentential Aspect Hypothesis (Sharma & Deo 2009) for perfective marking by L1 English learners of Mandarin. The AH predicts a narrow focus on inherent lexical aspect (the verb and predicate) in determining the use of the perfective marker le, whilst the SAH suggests that – subject to L1 influence – perfective marking agrees with the final derived aspectual class of the sentence. To test these claims data were collected using a controlled le-insertion task, combined with oral corpus data. The results show that learners’ perfective marking patterns with the sentential aspectual class and not inherent lexical aspect (where these differ), and that overall the sentential aspectual class better predicts learners’ assignment of perfective marking than lexical aspect.

Situated within a Systemic Functional Linguistics genre paradigm, this study adopted a function-based linguistic approach to examine the argument structures in English writing produced by Chinese university students of English as foreign language (EFL). Their English writing was contrasted with three other sets of argumentative essays in order to explore differences and similarities in the use of argument structures. The four sets of essays were produced by three groups of university students: native English- and Chinese-speaking university students and Chinese university EFL students. Participants’ interviews and questionnaire responses were also collected. The study found that most native English-speaking participants used an analytical arguing strategy, while most Chinese-speaking university participants preferred a hortatory argument structure both in their English and Chinese writing. It was also found that Chinese participants’ English writing was influenced by both English and Chinese.

This study contributes to ongoing discussions on how measures of lexical diversity (LD) can help discriminate between essays from second language learners of English, whose work has been assessed as belonging to levels B1 to C2 of the Common European Framework of Reference (CEFR). The focus is in particular on how different operationalisations of what constitutes a “different word” (type) impact on the LD measures themselves and on their ability to discriminate between CEFR levels. The results show that basic measures of LD, such as the number of different words, the TTR (Templin 1957) and the Index of Guiraud (Guiraud 1954) explain more variance in the CEFR levels than sophisticated measures, such as D (Malvern et al. 2004), HD-D (McCarthy and Jarvis 2007) and MTLD (McCarthy 2005) provided text length is kept constant across texts. A simple count of different words (defined as lemma’s and not as word families) was the best predictor of CEFR levels and explained 22 percent of the variance in overall scores on the Pearson Test of English Academic in essays written by 176 test takers.

Interest in third language (L3) acquisition has increased exponentially in recent years, due to its potential to inform long-lasting debates in theoretical linguistics, language acquisition and psycholinguistics. Researchers investigating child and adult L3 acquisition have, from the very beginning, considered the many different cognitive factors that constrain and condition the initial state and development of newly acquired languages, and their models have duly evolved to incorporate insights from the most recent findings in psycholinguistics, neurolinguistics and cognitive psychology. The articles in this Special Issue of Bilingualism: Language and Cognition, in dealing with issues such as age of acquisition, attrition, relearning, cognitive economy or the reliance on different memory systems –to name a few–, provide an accurate portrayal of current inquiry in the field, and are a particularly fine example of how instrumental research in language acquisition and other cognitive domains can be to one another.

Methods of approaching the study of discourse have developed rapidly in the last ten years, influenced by a growing interdisciplinary spirit among linguistics and anthropology, sociology, cognitive and cultural psychology and cultural studies, as well as among established sub-fields within linguistics itself. Among the more recent developments are an increasing ‘critical’ turn in discourse analysis, a growing interest in historical, ethnographic and corpus-based approaches to discourse, more concern with the social contexts in which discourse occurs, the social actions that it is used to take and the identities that are constructed through it, as well as a revaluation of what counts as ‘discourse’ to include multi-modal texts and interaction. Advances in Discourse Studies brings together contributions from leading scholars in the field, investigating the historical and theoretical relationships between new advances in discourse studies and pointing towards new directions for the future of the discipline. Featuring discussion questions, classroom projects and recommended readings at the end of each section, as well as case studies illustrating each approach discussed, this is an invaluable resource for students of interdisciplinary discourse analysis.

From emails relating to adoption over the Internet to discussions in the airline cockpit, the spoken or written texts we produce can have significant social consequences. The area of Mediated Discourse Analysis considers texts in their social and cultural contexts to explore the actions individuals take with texts - and the consequences of those actions. Discourse in Action: brings together leading scholars from around the world in the area of Mediated Discourse Analysis reveals ways in which its theory and methodology can be used in research into contemporary social situations explores real situations and draws on real data in each chapter shows how analysis of texts in their social contexts broadens our understanding of the real world. Taken together, the chapters provide a comprehensive overview to the field and present a range of current studies that address some of the most important questions facing students and researchers in linguistics, education, communication studies and other fields.

Much of the work in intercultural communication studies in the past decade, especially in the field of applied linguistics, has been devoted to ‘disinventing’ the notion of culture. The problem with the word ‘culture’ as it has been used in anthropology, sociology, and in everyday life, it has been pointed out, is that it is used as a noun, conceived of as something ‘solid,’ an essential set of traits or characteristics of certain people or groups, something people ‘have’ rather than something they ‘do’ (Scollon, Scollon, & Jones, 2012). Among the most famous statements of this position is Brain Street’s classic paper ‘Culture is a Verb’ (1993), in which he argues that culture should be treated as ‘a signifying process the active construction of meaning rather than the static and reified or nominalizing’ sense in which the word is often used in anthropology, some linguistics circles, and in everyday conversation.

This paper will consider the relationship between discourse analysis and creativity and elucidate the ways in which a discourse analytical approach to creativity might be distinguished from the ‘language and creativity’ approaches which currently dominate applied linguistics and sociolinguistics. In the ‘discourse and creativity’ approach I will be describing, creativity is located not in language per se, but in the strategic ways people use language in concrete situations in order to stimulate social change. I will explore how aspects of this approach are reflected in work carried out within the paradigm of world Englishes.

This paper explores the relationship between discourse and action in practices involved in making and consuming texts. Texts are produced through the process of ‘entextualization’ in which strips of action and discourse are extracted from their original contexts and recontextualized into other situations. Different technologies for turning actions into texts affect the kinds of social actions and social identities that are made possible both at moments of entextualization and at future moments of recontextualization. In particular, I focus on how digital technologies affect the practices and participation structures around entextualization. Digital photography and video have had a profound effect on social practices and relationships around the making of texts. Specifically, they have made processes of entextualization more immediate, more contingent and more communal. Implications of these features of digital text making are discussed in light of previous work on literacy and orality.

We investigate the practices by which bilingual university students in Hong Kong appropriate texts in producing utterances, particularly written texts. Following Wertsch and his colleagues we ask: • To what extent do our students appropriate texts in constructing their own discourses? • What linguistic means do they use to do this? • What can these processes tell us about what they now can do with discourse representation; and • What do we need to teach them? This research shows that our students' writing displays considerable intertextuality and interdiscursivity. Responses to this writing in tutorial sessions indicate that they are skilled at orchestrating the multiple voices within their own discourses. The commonly stated concern that our students do not know how to do quotation and citation correctly is somewhat misplaced and researchers need to move the focus away from the mechanisms of citation and attribution to the social practices of textual appropriation.

Using the novel technique of topic modelling, this paper examines thematic patterns and their changes over time in a large corpus of corporate social responsibility (CSR) reports produced in the oil sector. Whereas previous research on corporate communications has been small-scale or interested in selected lexical aspects and thematic categories identified ex ante, our approach allows for thematic patterns to emerge from the data. The analysis reveals a number of major trends and topic shifts pointing to changing practices of CSR. Nowadays ‘people’, ‘communities’ and ‘rights’ seem to be given more prominence, whereas ‘environmental protection’ appears to be less relevant. Using more established corpus-based methods, we subsequently explore two top phrases - ‘human rights’ and ‘climate change’ that were identified as representative of the shifting thematic patterns. Our approach strikes a balance between the purely quantitative and qualitative methodologies and offers applied linguists new ways of exploring discourse in large collections of texts.

Early American crania show a different morphological pattern from the one shared by late Native Americans. Although the origin of the diachronic morphological diversity seen on the continents is still debated, the distinct morphology of early Americans is well documented and widely dispersed. This morphology has been described extensively for South America, where larger samples are available. Here we test the hypotheses that the morphology of Early Americans results from retention of the morphological pattern of Late Pleistocene modern humans and that the occupation of the New World precedes the morphological differentiation that gave rise to recent Eurasian and American morphology. We compare Early American samples with European Upper Paleolithic skulls, the East Asian Zhoukoudian Upper Cave specimens and a series of 20 modern human reference crania. Canonical Analysis and Minimum Spanning Tree were used to assess the morphological affinities among the series, while Mantel and Dow-Cheverud tests based on Mahalanobis Squared Distances were used to test different evolutionary scenarios. Our results show strong morphological affinities among the early series irrespective of geographical origin, which together with the matrix analyses results favor the scenario of a late morphological differentiation of modern humans. We conclude that the geographic differentiation of modern human morphology is a late phenomenon that occurred after the initial settlement of the Americas. Am J Phys Anthropol 144:442-453, 2011.
