This book provides a clear introduction to the main methods of analyzing samples of learner language by examining the theoretical and research bases for each.

He is co-author of Analysing Learner Language, and author of Second Language Acquisition, SLA Research and Language Teaching, The Study of Language Acquisition, which won the English Speaking Union's Duke of Edinburgh Book Competition, Understanding Second Language Acquisition, which won the BAAL Book Prize, and Task-based Language Learning and Teaching, all published by Oxford University Press.
I absolutely love this book. Now I am not a genius or nerd. I used this in my SLA coursework and every class since then (functional and generative syntax, FLA, critical theoretical an applied linguistics, etc etc etc. I really enjoy this book as it teaches methodology and research basics using the scientific method. It has been critical to my high scores on term papers for these linguistics courses, as it presents the rubrics and great background information (and exercises) for data collection and analysis. I admit it might be more difficult to read and apply this information without instruction. However you may find something within the free online syllabi to augment that need. Definitely a recommended reading for linguistic students and professors alike.
A great resource for researchers in the language learning field. Ellis and Barkhuizen clearly lay out research methods and applications, along with outcomes and issues.
