Speaking is a central yet complex area of language acquisition. The assessment of this crucial skill is equally complex because of its interactive nature. This book takes teachers and language testers through the research on the assessment of speaking as well as through current tests of speaking. The book then guides language testers through the stages of test tasks, rating practices and design.

This book examines the crucial role that sound file selection plays in assessing listening ability and introduces the reader to the procedure of textmapping, which explores how to exploit a sound file. The book discusses the role of the task identifier, the task instructions and the example, and analyses the strengths and weaknesses of different test methods. Guidelines for developing listening items, and procedures that can be used in peer review and task revision are also provided. A range of sample listening tasks illustrates the benefits of following the test development approach described in the book. Developing Listening Tests also provides insights into the advantages that field trials, statistical analyses and standard setting can offer the language test developer in determining how well their tasks work. This practical book will be of interest to researchers, language testers, testing commissions, and teachers engaged in assessing listening performance around the world.

While research into aspects of standardised language tests is growing, the area of classroom-based language assessment (CBLA) is still not well-defined and relatively under-researched. Studies investigating CBLA practices within the ESL/EFL school contexts as well as the tertiary level have stressed the need for further research as the picture is not yet complete. The volume aims to address this challenge by presenting a wide scope of research interests that discuss theoretical and practical underpinnings of CBLA. It is also meant to promote the notion of CBLA for a wide membership of the language teaching and testing community covering topics that consider both realities and prospects of CBLA in the assessment world.

This contemporary presentation of statistical methods features extensive use of graphical displays for exploring data and for displaying the analysis. The authors demonstrate how to analyze data—showing code, graphics, and accompanying tabular listings—for all the methods they cover. They emphasize how to construct and interpret graphs. They discuss principles of graphical design. They identify situations where visual impressions from graphs may need confirmation from traditional tabular results. All chapters have exercises. The authors provide and discuss R functions for all the new graphical display formats. All graphs and tabular output in the book were constructed using these functions. Complete R scripts for all examples and figures are provided for readers to use as models for their own analyses. This book can serve as a standalone text for statistics majors at the master’s level and for other quantitatively oriented disciplines at the doctoral level, and as a reference book for researchers. In-depth discussions of regression analysis, analysis of variance, and design of experiments are followed by introductions to analysis of discrete bivariate data, nonparametrics, logistic regression, and ARIMA time series modeling. The authors illustrate classical concepts and techniques with a variety of case studies using both newer graphical tools and traditional tabular displays. The Second Edition features graphs that are completely redrawn using the more powerful graphics infrastructure provided by R's lattice package. There are new sections in several of the chapters, revised sections in all chapters and several completely new appendices. New graphical material includes: • an expanded chapter on graphics • a section on graphing Likert Scale Data to build on the importance of rating scales in fields from population studies to psychometrics • a discussion on design of graphics that will work for readers with color-deficient vision • an expanded discussion on the design of multi-panel graphics • expanded and new sections in the discrete bivariate statistics capter on the use of mosaic plots for contingency tables including the n×2×2 tables for which the Mantel–Haenszel–Cochran test is appropriate • an interactive (using the shiny package) presentation of the graphics for the normal and t-tables that is introduced early and used in many chapters The new appendices include discussions of R, the HH package designed for R (the material in the HH package was distributed as a set of standalone functions with the First Edition of this book), the R Commander package, the RExcel system, the shiny package, and a minimal discussion on writing R packages. There is a new appendix on computational precision illustrating and explaining the FAQ (Frequently Asked Questions) about the differences between the familiar real number system and the less-familiar floating point system used in computers. The probability distributions appendix has been expanded to include more distributions (all the distributions in base R) and to include graphs of each. The editing appendix from the First Edition has been split into four expanded appendices—on working style, writing style, use of a powerful editor, and use of LaTeX for document preparation.
