Dissertation Themes

As I’ve wrapped up numerous cycles of qualitative coding of interview data for my dissertation, Into the edu-verse: New teachers’ agency in self-directed learning with social media, I used geom_tile() in {ggplot2} to create heatmap plots to help me quickly visualize how thematic codes varied by interview participant and by modality.

I’ve shared the code to produce these plots in a GitHub repository, and you can also view on RPubs a variety of different heatmaps I created en route to these final plots.

My research focuses on networked learning, specifically, how social media platforms can support induction and ongoing professional learning for K-20 educators.
