In lieu of a conclusion, the book ends with a survey of the basic reference and research tools currently available to scholars and enthusiasts alike.

This chapter describes tools that have been used to measure the effectiveness of corrective feedback ranging from classic instruments such as interactive tasks, to innovative methods recently adopted from related fields like psychology and educational measurement. As part of describing these measurement tools, we also discuss how factors in their use, such as the instructions, the participants, and their roles, need to be considered when assessing the efficacy of feedback. We describe tools used in classrooms and laboratory settings, including introspective methods such as think-alouds, immediate recalls, stimulated recall, interviews, journals, blogs, and uptake sheets, as well as external measurements. We outline the use of tasks in both face-to-face and computer-mediated contexts. We conclude our chapter with a discussion of future directions in measuring the effectiveness of corrective feedback on linguistic development and pedagogical implications.
