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

Today’s program› Introduction
Origin of the data we’re working with today Coding video data – how to? Introduction to Mediacoder (Bos & Steenbeek, 2006)
› Make your own coding system and code data
› First analysis with your codings

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)

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)
