Applying a Gesture Taxonomy to Introductory Computing Concepts.

Gestures, or spontaneous hand movements produced when talking, are an untapped resource for understanding student knowledge in computing education. This paper develops a conceptual framework to support future studies of learning and teaching that incorporate gesture studies in programming contexts. In particular, this paper introduces how gesture has been used to study teaching and learning in another discipline, mathematics; critically reviews and interprets what concepts and methods may be most relevant to programming contexts; and also discusses what unique challenges programming contexts present to studies of gesture (e.g. differences in abstract versus concrete). We ground our understandings of gesture by using an observational study where we observed novice students learning to program. This paper concludes by suggesting potential avenues for future research in computing education that incorporate analyses of gesture in studies of teaching and learning.
