This paper introduces and exemplifies a qualitative method for studying learning, "microgenetic learning analysis" (MLA), which is aimed jointly at developing theory and at establishing useful empirical results. Among modern methodologies, the focus on theory is somewhat distinctive. We use two strategies to describe MLA. First, we develop a…

Although noting the value of baby diaries, proposes a revival of similar methods that would enable researchers to address some of the fundamental issues in child…
