Improvisations provides readers with insights and options as they develop new lifespan writing research projects or seek to re-orient existing projects to incorporate a lifespan lens. In Part 1 of this edited collection, contributors consider research methodologies that have been adapted to the particular demands of lifespan writing research, with each methodology given two chapters: one that outlines the process of taking up the methodology, and another that provides a detailed example of the methodology in action. In Part 2, contributors suggest new methodologies for lifespan writing research and highlight challenges that this line of inquiry presents as an ethical and socially conscious research agenda. These chapters, representing both established experts and new voices in writing, literacy, and education research, will be of use to graduate students and novice researchers, accomplished researchers pivoting to this area of study for the first time, and others who want to learn more about lifespan writing research.
