Based on the analysis of a specially compiled corpus of internationally recognized English as a foreign language (EFL) reading tests at different levels of proficiency, this volume explores the relation between the complexity of written texts and the difficulty of reading comprehension tests. It brings together linguistic investigations into the text-inherent complexity of the tests and a study of the data derived from their administration to groups of Italian university students. The study of text complexity draws on corpus linguistics, text linguistics and systemic functional linguistics. Both quantitative and qualitative analyses are carried out on the language used in the reading texts and in the related tasks that make up the corpus of tests. The assessment of test difficulty, on the other hand, is informed by research on language testing, and, in particular, by findings and methodologies of Classical Test Theory and Item Response Theory. Relevant aspects of these theories are used to analyze and interpret both the data obtained from the administration of the tests and the data collected by means of feedback questionnaires completed by test takers. The application of such diverse methodologies and the subsequent comparison of the results of the analyses has brought out interesting correlations between text-inherent complexity, perceived test difficulty and actual test difficulty.

Using corpus-based analyses, the book challenges widely held beliefs about grammatical complexity, academic writing, and linguistic change in written English.

Language complexity has recently attracted considerable attention from linguists of many different persuasions. This volume – a thematic selection of papers from the conference Approaches to Complexity in Language, held in Helsinki, August 2005 – is the first collection of articles devoted to the topic. The sixteen chapters of the volume approach the notion of language complexity from a variety of perspectives. The papers are divided into three thematic sections that reflect the central themes of the book: Typology and theory, Contact and change, Creoles and pidgins. The book is mainly intended for typologists, historical linguists, contact linguists and creolists, as well as all linguists interested in language complexity in general. As the first collective volume on a very topical theme, the book is expected to be of lasting interest to the linguistic community.

This book characterises the diverse morphological complexity we find in the languages of the world. Richly illustrated, examples are drawn from dozens of different languages and are subjected to rigorous quantitative analysis. It will be ideal reading for academic researchers and graduate students of linguistics, with a special interest in morphology and English language.

This book studies linguistic complexity and the processes by which it arises and is maintained, focusing not so much on what one can say in a language as how it is said. Complexity is not seen as synonymous with “difficulty” but as an objective property of a system — a measure of the amount of information needed to describe or reconstruct it. Grammatical complexity is the result of historical processes often subsumed under the rubric of grammaticalization and involves what can be called mature linguistic phenomena, that is, features that take time to develop. The nature and characteristics of such processes are discussed in detail, as well as the external and internal factors that favor or disfavor stability and change in language.

With the advent and increasing popularity of Computer Supported Collaborative Learning (CSCL) and e-learning technologies, the need of automatic assessment and of teacher/tutor support for the two tightly intertwined activities of comprehension of reading materials and of collaboration among peers has grown significantly. In this context, a polyphonic model of discourse derived from Bakhtin’s work as a paradigm is used for analyzing both general texts and CSCL conversations in a unique framework focused on different facets of textual cohesion. As specificity of our analysis, the individual learning perspective is focused on the identification of reading strategies and on providing a multi-dimensional textual complexity model, whereas the collaborative learning dimension is centered on the evaluation of participants’ involvement, as well as on collaboration assessment. Our approach based on advanced Natural Language Processing techniques provides a qualitative estimation of the learning process and enhances understanding as a “mediator of learning” by providing automated feedback to both learners and teachers or tutors. The main benefits are its flexibility, extensibility and nevertheless specificity for covering multiple stages, starting from reading classroom materials, to discussing on specific topics in a collaborative manner and finishing the feedback loop by verbalizing metacognitive thoughts.
