  1. Analysis of dialogues in education Applying DST to teacher-student interactions Henderien Steenbeek Steffie van der Steen

  2. 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 question 2) Test your hypotheses

  3. 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

  4. 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

  5. Example of the research setting

  6. 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?

  7. Example of a coding system

  8. 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)

  9. Introduction to Mediacoder

  10. Construction of coding system

  11. First data analysis in Excel • Making a time serial illustration of your data
