Diary studies involve language learners or teachers keeping journals over time using introspection. This allows insight into aspects of the language learning process not normally accessible. A few published diary studies have looked at different aspects of the learning and teaching process, but findings are difficult to compare due to small sample sizes. To analyze diaries, one should consider the content, context, and form of the narrative. Diaries provide qualitative data about factors influencing individuals' language learning experiences and processes.
