DST approach to interactions› A DST / process approach to study interactions

entails observing behavior or phenomena

› It is useful to convert these observations in codings to:

1) Describe the interaction in light of your research question2) Test your hypotheses

Origin of the video data› Longitudinal micro-developmental study on young

children’s understanding of scientific concepts

› Research question: how does understanding of scientific concepts develop, taking into account the real-time interactions that constitute this process and the vast amount of intra-individual variability?

› Data collection: 10 visits in 3 years, hands-on exploration of air pressure/gravity tasks under guidance of the researcher, who asks questions

Coding systems› Usually based on theory, or the behavior you

wish to study› Only relevant behaviors/utterances are coded› Exhaustive coding systems code all (or most)

behaviors, and usually have a “other” category› Should be reliable, i.e. categories cannot be

ambiguous (it should be clear which behavior belongs to which category)

Rabbit or duck?

Make your own coding system› On your laptops: a few minutes of video data

from the longitudinal study

› Coding systems can be made for utterances, behavior, emotions, motivation, manipulations of the material, understanding of a task, etcetera...

› After constructing the coding system: code the data using Mediacoder (Bos & Steenbeek, 2006)
