  • Math hashtags on Twitter

    Back in November, Judy Larsen posted this tweet about math hashtags. Judy’s question got me thinking about all the math hashtags that really are used on Twitter. What are they? To answer this question, I downloaded the #MTBoS and #ITeachMath hashtags using NodeXL software, and went through all the hashtags mentioned in those data sets.…

  • Calculating betweenness centrality using NodeXL

    For my dissertation, a statistic I used to determine who was at the “center” of the network was the centrality calculation. This was not done by hand. I used software called NodeXL to do the downloading, calculating, and visualization of the network. The statistic ended up choosing to use is called the Betweenness Centrality, which…

  • PhD: Y’all need to get some sleep 2

    Wow. So much to learn when dealing with software packages and analysis. It turns out that our computers do a TON of processing behind the scenes. When I send a tweet, Tweetdeck and / or Twitter shows the time of tweet as being a couple of minutes ago, and then the time counts from there.…

  • Writing my methods section: a mixed method look at TMC17 part 2

    On to the qualitative analysis.

The problem, then, is that there is not a clear definition of the ‘community.’ Anyone who says they are a member…

I thought this…

  • #Made4Math–homework research

    Homework, to give, nor not? How much to give? How much is too much? What purpose does it serve? What is the purpose in assigning it? I will be honest, I don’t have answers to these questions, but I do have some research, some documents downloaded that may help you shape your own answers to…
